Smartphones usually rely on batteries to provide power, and the size and capacity of the battery are limited by the overall size and weight of the smartphone, and cannot be made too large. How to reduce the power consumption of smart phones and extend the standby time of smart phones has become an important issue in the industry.

In order to solve this problem, the prior art provides a power saving mode of a smart phone, in which some functions or hardware modules of the smart phone will be in a closed state, or the hardware module will be operated in a low power state, thereby Reduce the consumption of electricity. There are also many ways in which a smartphone can enter a power saving mode. For example, the smart phone automatically enters the power saving mode during the power saving period, or the smart phone automatically enters the power saving mode when the remaining battery power is less than a certain threshold. However, this type of mode of entering a power saving mode cannot be controlled by the user and lacks flexibility.

In order to allow the mobile terminal to enter the power saving mode from the normal mode, there are multiple implementations. One of the ways is that when the mobile terminal receives an instruction from the user to enter the power saving mode, the mobile terminal enters the power saving mode. There are various ways for the user to issue the command, such as voice commands, tap operations, touch operations, shaking mobile terminals, and the like. Another way is to enter the power saving mode when the mobile terminal detects that some conditions are met, for example, the mobile terminal detects that the remaining power is less than a certain threshold, or detects that the power saving time period currently set by the user, or combines The state in which the user holds the mobile terminal and the current usage state of the mobile terminal determines that the mobile terminal is currently idle (the implementation manner thereof may refer to the Chinese application CN201210112165.9).

Correspondingly, in order to let the mobile terminal enter the normal mode from the power saving mode, there are also multiple implementation manners. One of the ways is that when the mobile terminal receives an instruction from the user to enter the power saving mode, the mobile terminal enters the power saving mode. There are various ways for the user to issue the command, such as voice commands, tap operations, touch operations, shaking mobile terminals, and the like. When the mobile terminal detects that some conditions are met, the power saving mode is exited, for example, the mobile terminal detects that the remaining power is greater than a certain threshold, or detects a time period that is currently outside the power saving time period set by the user, or combines The state in which the user holds the mobile terminal and the current usage state of the mobile terminal determines that the mobile terminal is currently used by the user (the implementation manner thereof may refer to the Chinese application CN201210112165.9).

In the prior art, as in U.S. Application No. 8,118,747 B2, a solution for allowing the handheld electronic device to enter the power saving mode and exit the power saving mode is also provided. The solution detects the acceleration on the X-axis, the acceleration on the Y-axis, and the acceleration on the Z-axis through the gravity sensor of the handheld electronic device, and determines whether the acceleration on the three axes falls within a preset range, and if so, the hand-held The electronic device enters a power saving mode, and if not, the handheld electronic device returns to a normal operating mode. The solution does not consider the case where the handheld electronic device is held by the user. When the user holds the handheld electronic device and the handheld electronic device maintains a horizontal posture facing downward, according to the solution, the handheld electronic device enters the power saving manner. Mode, however, since the user is holding the handheld electronic device at this time, it usually means that the user still wants to use the handheld electronic device at this time. If the power saving mode is entered, it is easy for the user to use some functions that are turned off because of entering the power saving mode. Thereby affecting the normal use of the handheld electronic device by the user. On the other hand, the solution does not return to the normal operation mode when the handheld electronic device is picked up by the user in a horizontally facing downward posture, and when the user picks up the handheld electronic device, the user usually wants to use it. The handheld electronic device, therefore, also causes a misjudgment of exiting the power saving mode, thereby affecting the user experience.

In the embodiment of the present invention, a function of quickly entering/entering the power saving mode is provided, where “/” indicates “or”, and the fast entry/exit power saving mode function combines the power saving mode and the power saving mode. Two The function enables the user to conveniently enter the power saving mode and exit the power saving mode by changing the placement mode of the mobile terminal, and the accuracy is relatively high. When the user turns on the function, when the mobile terminal is placed horizontally in a face-down direction and is placed on the stationary object instead of the user's hand, the mobile terminal enters the power saving mode without the user's operation. At this time, the situation that the mobile terminal still enters the power saving mode when the mobile terminal is held by the user does not occur, thereby reducing the misjudgment of entering the power saving mode and improving the accuracy of entering the power saving mode. When the state of the mobile terminal changes and is no longer in the state of the stationary object placed horizontally downward, for example, picked up by the user or turned into vertical, the mobile terminal enters the normal state without the user's operation. Mode, the way of exiting the power saving mode can recognize that the user picks up the mobile terminal in a direction facing downward, can reduce the false judgment of exiting the power saving mode, and improve the accuracy of exiting the power saving mode. When the user does not enable the function, the mobile terminal can perform normal work with reference to the prior art. One implementation manner is to add an option or button of the function of quickly entering or leaving the power saving mode to the power management interface or the shortcut function menu in the mobile terminal, and the user selects to turn on and off. Another implementation manner is that a certain hardware button or button in the mobile terminal is associated with the function of the fast entry/exit power saving mode, and the user can implement the function of the fast entry/exit power saving mode by operating the hardware button. Turn it on and off. In another implementation manner, other functions such as a voice, a gesture, and the like are defined to implement the function of quickly entering/entering the power saving mode, which is not limited by the present invention.

It can be understood that the function of quickly entering the power saving mode and the function of quickly leaving the power saving mode can be separately selected and controlled by the user as two independent options. If the user only enables the function of quickly entering the power saving mode without turning on the function of quickly exiting the power saving mode, the mobile terminal only supports changing the placement mode of the mobile terminal, so that the mobile terminal can conveniently enter the power saving mode without supporting the change of the mobile terminal. The way the terminal is placed allows the mobile terminal to conveniently exit the power saving mode. The reverse is also similar, and will not be repeated here.

The first duration and the second duration in the embodiment of the present invention may be the same or different, and the present invention does not limit this. In one embodiment, the first duration is used to determine whether the mobile terminal is in a horizontally placed, face down orientation. If the accelerations detected by the gravitational acceleration sensor on the X axis, the Y axis, and the Z axis are respectively maintained at 0, 0, -9.8 m/s ² for the first duration, it is determined that the mobile terminal is face down The state of the horizontal placement. In another embodiment, the second duration is used to determine if the mobile terminal is placed on a stationary object. If the noise detected by the gravitational acceleration sensor is below the noise threshold for the second duration, it is determined that the mobile terminal is placed on a stationary object without being held by the user.

The energy threshold in the embodiment of the present invention is used to determine whether there is object coverage on the front side of the mobile terminal, and the energy threshold may be set to a value close to the energy emitted by the infrared sensor, for example, 90% of the energy emitted by the infrared sensor or 80%, etc., the invention is not limited thereto.

The pressure threshold value in the embodiment of the present invention is used for determining the force on the back side of the mobile terminal, and the pressure threshold value may be set to a value close to 0, such as 0.1 Newton or 0.05 Newton, etc., when the pressure detected by the pressure sensor Below the pressure threshold, there is no object contact on the back of the mobile terminal, and the pressure detected by the pressure sensor is higher than the pressure threshold, indicating that there is object contact on the back of the mobile terminal.

The numerical ranges of "close" and "about" given in the embodiments of the present invention are merely examples, and those skilled in the art may also set other numerical ranges according to experimental data or user habits and the like.

Hereinafter, the mobile terminal is taken as an example for the mobile phone. It can be understood that the following embodiments are also applicable to other mobile terminals having a gravity sensor.

The memory 120 is used to store software programs and modules, and the processor 180 executes various functional applications and data processing of the mobile phone 100 by running software programs and modules stored in the memory 120. The memory 120 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application required for at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may be stored. Data created according to the use of the mobile phone 100 (such as audio data, phone book, etc.). Moreover, memory 120 can include high speed random access memory, and can also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 130 is configured to receive input numeric or character information, and generate a key signal input related to user settings and function control of the mobile phone 100. Specifically, the input unit 130 may include a touch panel 131 and other input devices 132. A touch panel 131, also referred to as a touch screen, can collect users in it a touch operation on or near (such as a user using a finger or a stylus or the like on the touch panel 131 or in the vicinity of the touch panel 131), and driving the corresponding connection device according to a preset program . The touch panel 131 includes two parts of a touch detection device and a touch controller. Wherein, the touch detection device detects the touch orientation of the user, and detects a signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts the touch information into contact coordinates, and sends the touch information. The processor 180 is provided and can receive commands from the processor 180 and execute them. In addition, the touch panel 131 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 131, the input unit 130 may also include other input devices 132. Specifically, other input devices 132 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control buttons, switch buttons, etc.), trackballs, mice, joysticks, and the like.

The display unit 140 is for displaying information input by the user or information provided to the user and various menus of the mobile phone 100. The display unit 140 may include a display panel 141. Alternatively, the display panel 141 may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), or the like. Further, the touch panel 131 can cover the display panel 141. When the touch panel 131 detects a touch operation on or near the touch panel 131, the touch panel 131 transmits to the processor 180 to determine the type of the touch event, and then the processor 180 according to the touch event. The type provides a corresponding visual output on display panel 141. Although the touch panel 131 and the display panel 141 are used as two independent modules to implement the input and input functions of the mobile phone 100 in FIG. 1, in some embodiments, the touch panel 131 may be integrated with the display panel 141. The input and output functions of the mobile phone 100 are implemented. The screen of the embodiment of the present invention includes at least one of the touch panel 131 and the display panel 141. Specifically, the display panel 141 is configured to display an interface for setting a function of the fast entry/exit power saving mode, and the touch panel 131 is configured to receive an instruction input by the user to enable the fast entry/exit power saving mode, and close the An instruction to quickly enter/leave the function of the power saving mode.

It should be noted that the mobile phone usually includes a front side, a back side and a side side. The front and back of the phone are opposite, with four sides between the front and back. The front side of the mobile phone generally includes a display panel 141, and optionally, a touch panel 131 and some buttons. The back of the phone generally includes a camera, optional, and some manufacturers' logos. At least one of the following is generally provided on the side of the mobile phone: a volume button, a power button, a power port, a USB port, and a headphone jack. As shown in Figure 2a, the back of the phone touches the desktop, and the front and sides of the phone do not touch the desktop. As shown in Figure 2b, the front of the phone touches the desktop, and the back and sides of the phone do not touch the desktop. As shown in FIG. 3b, the user holds the mobile phone, wherein the user's thumb touches the front of the mobile phone, and the user's index finger and middle finger touch the side and back of the mobile phone.

It should be noted that the following uses the same surface of the touch panel 131 and the display panel 141 on the mobile phone as an example. When the mobile phone is placed face down (as shown in FIGS. 2b and 3b), it also means This means that the mobile phone is placed with the touch panel 131 facing down and 141 also facing down. When the mobile phone is placed in a face-up manner (as shown in FIGS. 2a and 3a), it means that the mobile phone is also placed in such a manner that the touch panel 131 is upward and the display panel 141 is also upward. It can be understood that the touch panel 131 and the display panel 141 can also be located on different faces of the mobile phone. In this case, the determination can be made based on the placement mode of the display panel 141.

The mobile phone 100 also includes a gravity sensor 150 that is capable of detecting the component of the gravitational acceleration in various directions (typically the three axes of the three-dimensional Cartesian coordinate system of the handset) for identifying the status of the handset.

The unit in which the gravity sensor 150 can detect the component of the gravitational acceleration may be meters per second ² (m/s ² ), or g, where 1 g = 9.8 m/s ² (m/s ² ). The relationship between the three-dimensional Cartesian coordinate system and the mobile phone can be as shown in FIG. 2a (other coordinate systems can also be used, which is not limited in the embodiment of the present invention), wherein the mobile phone 100 faces up according to the touch panel 131 (or the display panel 141). The orientation is placed on the desktop 200 and the desktop 200 is horizontal. Hereinafter, the touch panel 131 will be described as an example. The origin of the coordinate system is the geometric center of the mobile phone or the touch panel 13, the Z axis is perpendicular to the touch panel 131, and points to the direction other than the front side of the touch panel 131 (ie, the side on which the user performs the touch operation), the X axis and the Y axis. The axis is in a horizontal plane, the X axis is parallel to the shorter side of the touch panel 131, and points to the right side as shown in the figure, the Y axis is parallel to the longer side of the touch panel 131, and is pointed as shown in the figure. Above. After the mobile phone is stabilized on the desktop 200, the accelerations on the X-axis and the Y-axis detected by the gravity sensor 150 are both 0, and the acceleration on the Z-axis detected by the gravity sensor 150 is approximately equal to the standard gravity acceleration 1 g=9.8 m/sec ² (m/s ² ). The same three-dimensional Cartesian coordinate system is still used. When the mobile phone 100 is placed on the desktop 200 in the downward direction of the touch panel 131 (as shown in FIG. 2b), and the desktop 200 is horizontal, the mobile phone is on the desktop 200. After the upper stabilization, the accelerations on the X-axis and the Y-axis detected by the gravity sensor 150 are both 0, and the acceleration on the Z-axis detected by the gravity sensor 150 is approximately equal to the acceleration of gravity -9.8 m/s ² . Therefore, by determining whether the acceleration on the Z-axis is negative, it can be determined whether the touch panel 131 is facing downward or not, and whether the acceleration of the X-axis and the Y-axis direction is 0 or not, whether the touch panel 131 is horizontal or not can be determined. If you consider that the desktop placed on the phone is not absolutely level, determine if the acceleration in the X-axis and Y-axis directions is a small value close to 0 (for example, between -1 m / s ² to 1 m / s ² or other intervals) Specifically, it may be set by a user or set by experimental data to determine whether the touch panel 131 is substantially horizontal.

The gravity sensor 150 can also detect the noise of the acceleration, that is, the amount of change in the gravitational acceleration, for example:

. It can be understood that the noise of the acceleration may also be other calculation manners, which is not limited by the embodiment of the present invention. When the mobile phone 100 is placed on an object that is stationary (ie, not moving), such as a horizontal desktop, and is not held in the user's hand, the time curve of the noise of the acceleration detected by the gravity sensor 150 is as shown in FIG. The abscissa is milliseconds (ms) and the ordinate is g. From this curve, when the mobile phone is placed on a stationary object, such as a horizontal, non-moving desktop, and is not held in the user's hand, the detected acceleration noise is relatively small, generally less than 0.004 g. When the mobile phone 100 is held in the hand by the stationary user and remains stable (for example, as shown in FIGS. 3a and 3b), the time curve of the noise of the acceleration detected by the gravity sensor 150 is as shown in FIG. 5, which is measured in the figure. The value of the noise of the acceleration is generally greater than 0.1 g. This small noise is mainly caused by the influence of the user's pulse and minute jitter. It can be seen that the values of the noise of the accelerations in FIG. 4 and FIG. 5 are significantly different. By determining whether the noise of the acceleration detected by the gravity sensor 150 is less than a noise threshold, it can be determined whether the mobile phone 100 is placed on a stationary object. If the noise threshold is set small enough, such as 0.004g, it can be relatively accurately determined whether the mobile phone 100 is held by the user.

It should be noted that the noise threshold mentioned in the embodiment of the present invention may be set to other values in addition to 0.004 g. If the mobile phone is placed on a stationary desktop, the gravity sensor 150 can detect the acceleration noise as G1; the mobile phone is stably held by the user in the hand, and when the user is stationary, the gravity sensor 150 can detect the acceleration noise as G2; The user carries it in a pocket or a backpack, and when the user is exercising, such as walking, running, or riding a vehicle, the gravity 150 can detect the acceleration noise as G3. Since G3>G2>G1. Setting the noise threshold G0 to be greater than G1 and less than any value of G2, for example, setting G0 to any value between 0.0038 g and 0.01 g, such as 0.004 g, by comparing the noise of the acceleration detected by the gravity sensor with The noise threshold can determine that the mobile phone is placed on a stationary object, rather than being carried by a moving user in a pocket or backpack, or even held by a stationary user.

The mobile phone 100 further includes a pressure sensor 151 disposed on the back of the mobile phone 100 (i.e., without the touch panel 131 and the side of the display panel 141). The pressure sensor is used to detect the pressure on the back of the mobile phone. For accurate measurement, it can be evenly distributed over the entire area of the back, or the back pressure sensor can be placed in a designated area on the back of the mobile phone according to the specific situation, such as the rear camera on the back. Near, around the four corners and around the four sides. Hereinafter, the pressure sensor 151 is uniformly distributed over the entire area of the back surface as an example. When the current state of the mobile phone is that the touch panel 131 (or the display panel 141) is placed on the object upward, the pressure sensor detects the location. The force on the back of the phone is M1, the M1 is greater than 0, which is generally the gravity of the mobile phone itself; when the current state of the mobile phone is that the touch panel 131 (or the display panel 141) is placed down on the object, the pressure sensor detects the back of the mobile phone. When the current state of the mobile phone is the user's grip, the pressure sensor detects that the force on the back of the mobile terminal is M2, and M2 is generally greater than zero.

The handset 100 may also include other sensors, such as infrared sensors (not shown). The infrared sensor is placed on the front of the phone. The infrared sensor is used for detecting the reflected energy and wavelength. If the reflected energy is relatively large (greater than an energy threshold), the energy emitted by the infrared sensor is close to the front surface of the mobile phone 100, if the reflected energy is reflected. Very small (less than one energy threshold), indicating that there is no object obstruction on the front of the mobile phone 100. There may be one infrared sensor, which is disposed above the display panel 141, or near the front camera, or at least two, which are respectively disposed above and below the display panel 141.

The mobile phone 100 may further include a light sensor, which may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 141 according to the brightness of the ambient light, and the proximity sensor may move when the mobile phone 100 moves to the ear , the display panel 141 and/or the backlight are turned off. Other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and the like that can be configured in the mobile phone 100 will not be described herein. There may be one light sensor disposed above the display panel 141 or near the front camera, or at least two, respectively disposed above and below the display panel 141.

The audio circuit 160, the speaker 161, and the microphone 162 provide an audio interface between the user and the handset 100. The audio circuit 160 transmits the received audio signal converted by the audio data to the speaker 161, and is converted into a sound signal output by the speaker 161. On the other hand, the microphone 162 converts the collected sound signal into an electrical signal, which is received by the audio circuit 160. It is then converted to audio data, which is then output to RF circuitry 108 for transmission to, for example, another handset, or audio data is output to memory 120 for further processing.

WiFi is a short-range wireless transmission technology. The mobile phone 100 transmits and receives emails, browses web pages, and accesses streaming media through the WiFi module 170, and provides wireless broadband Internet access for users. Although FIG. 1 shows the WiFi module 170, it can be understood that it does not belong to the essential configuration of the mobile phone 100, and may be omitted as needed within the scope of not changing the essence of the invention.

The processor 180 is the control center of the handset 100, connecting various portions of the entire handset with various interfaces and lines, by running or executing software programs and/or modules stored in the memory 120, and recalling data stored in the memory 120, The various functions and processing data of the mobile phone 100 are executed to perform overall monitoring of the mobile phone. Optionally, the processor 180 may include one or more processing units; preferably, the processor 180 may integrate an application processor (AP) and a modem processor, and may further include a microcontroller (Microcontroller Unit, MCU), wherein the application processor mainly processes an operating system, a user interface, an application, etc., the modem processor mainly processes wireless communication, and the microcontroller can share some work of the application processor. It can be understood that the above modem processor may not be integrated into the processor 180.

The processor 180 determines whether the mobile phone 100 is placed in a substantially horizontal manner in the downward direction of the touch panel 131, and includes any one of the following: (1) The processor 180 determines whether the accelerations on the X-axis, the Y-axis, and the Z-axis are respectively 0. 0, -9.8m/s ² , if yes, it can be determined that the mobile phone 100 is placed in a substantially horizontal direction according to the downward direction of the touch panel 131; (2) the processor 180 determines the reflected energy and the reflected wavelength detected by the infrared sensor. If the reflected energy is large (greater than the energy threshold) and the reflection wavelength corresponds to wood or glass, it can be determined that the mobile phone 100 is placed on the table according to the touch panel 131, and then the acceleration on the X-axis and the Y-axis is further determined. 0, if yes, it can be determined that the mobile phone 100 is placed on the desktop substantially horizontally according to the downward direction of the touch panel 131; (3) the processor 180 determines whether the pressure detected by the pressure sensor 151 on the back of the mobile phone 100 is close to 0. If yes, it is determined that the acceleration of the X-axis and the Y-axis is 0 according to the downward direction of the touch panel 131. If yes, it can be determined that the mobile phone 100 is in accordance with the touch panel 131. A substantially horizontal direction is placed on the desktop.

Further, the processor 180 can determine whether the mobile phone 100 is placed on a stationary object by the magnitude of the noise of the acceleration. Only when the processor 180 determines that the mobile phone 100 is placed on a stationary object in a substantially horizontal direction in the downward direction of the touch panel 131, the processor 180 controls the mobile phone to enter a power saving mode, for example, turning off the GPS module, disabling the earphone insertion detection function, and turning off Reminder of the indicator light, stop the detection of USB plug and play, close some of the multiple processing units in the processor, and so on. In this case, at this time, the user generally does not want to use the mobile phone, or does not rush to use the mobile phone to receive and reply to the message, so entering the power saving mode does not affect the user's use. When the gravity sensor detects that the state of the mobile phone 100 has changed, such as being picked up by the user, or the user flips the mobile phone such that the touch panel is not facing substantially horizontally downward, the processor 180 controls the mobile phone to exit the power saving mode, thereby recovering. Go to normal mode.

The mobile phone 100 also includes a power source 190 (such as a battery) that supplies power to the various modules. Preferably, the power source can be logically coupled to the processor 180 through a power management system to manage functions such as charging, discharging, and power consumption through the power management system.

Although not shown, the mobile phone 100 may further include a camera, a Bluetooth module, and the like, and details are not described herein.

The following takes a specific scenario as an example for description.

The user is using the mobile phone as shown in FIG. 1 , the mobile phone is in a normal state, the touch panel 131 receives a plurality of instructions from the user, and the processor 180 respectively starts the navigation application, the web browser, the photo application, and the instant according to multiple instructions of the user. Communication software, and the GPS module is turned on and the music file is downloaded using the WiFi module. The touch panel 131 then receives an instruction from the user to return to the main interface, and the processor 180 controls the display panel 141 to display the main interface instead of displaying the interfaces of the various applications that were previously opened, since the user does not close the applications, the processor 180 still running these apps in the background. Then, the touch panel 131 receives the operation of opening the power management interface of the user, the display panel 141 displays the power management interface, the touch panel 131 receives the user's selection operation, and the processor 180 starts the quick entry according to the selection operation. The function of leaving the power saving mode.

Subsequently, the user enters the conference room with the mobile phone, and the stationary horizontal table 200 is placed in the conference room. At the beginning, the user places the mobile phone on the horizontal desktop according to the touch panel 131 shown in FIG. 2a. When the processor 180 determines that the acceleration on the Z axis detected by the gravity sensor 150 is positive, the processor 180 maintains the application opened by the user in the background, and continues to download the music file using the WiFi module (assuming that the music file is downloaded at this time) undone).

When the user picks up the mobile phone from the desktop, according to the horizontal touch of the touch panel 131 of the mobile phone as shown in FIG. 3a, and maintains a stable state, at this time, 180 determines the Z-axis detected by the gravity sensor 150. If the acceleration is positive, the processor 180 still maintains various applications opened by the user in the background, and keeps the GPS module open, and continues to use the WiFi module to download music files (assuming that the music file download is not completed at this time).

When the user flips the mobile phone, that is, according to the horizontal touch of the mobile phone touch panel 131 as shown in FIG. 3b, the processor 180 first determines that the acceleration on the Z-axis detected by the gravity sensor 150 is negative. And substantially -9.8 m/s ² , then the processor 180 continues to determine that the acceleration on the X-axis detected by the gravity sensor 150 and the acceleration on the Y-axis are substantially zero, and then the processor 180 determines the detected by the gravity sensor 150. Whether the acceleration in the Z direction, the acceleration on the X axis, and the acceleration on the Y axis last for 5 seconds or more are approximately -9.8 m/s ² , 0 and 0, respectively. If the result of the determination is yes, the processor 180 continues to determine whether the average value of the noise of the acceleration detected by the gravity sensor 150 within the above 5 seconds is less than the noise threshold (here set to 0.004 g) due to the user's pulse and arm muscles. The effect of the jitter, where the processor 180 determines that the noise of the acceleration detected by the gravity sensor 150 is greater than the noise threshold, so the processor 180 still maintains various applications previously opened by the user in the background, keeps the GPS module open, and continues Use the WiFi module to download music files (assuming the music file download is not completed at this time).

When the user continues to move with the mobile phone facing down, and finally the mobile phone is placed on the horizontal desktop facing down according to the touch panel 131 shown in Fig. 2b, and no longer touches the mobile phone. At this time, the processor 180 first determines that the acceleration on the Z-axis detected by the gravity sensor 150 is negative, and is approximately -9.8 m/s ² , and then the processor 180 continues to determine the X-axis and Y detected by the gravity sensor 150. The acceleration on the shaft is substantially zero, and then the processor 180 determines whether the acceleration in the Z direction detected by the gravity sensor 150, the acceleration on the X axis, and the acceleration on the Y axis last for more than 5 seconds, respectively, being approximately -9.8 m/s ² , 0 and 0. If the determination is yes, the processor 180 then determines whether the average value of the noise of the acceleration detected by the gravity sensor 150 within the above 5 seconds is less than the noise threshold (here set to 0.004 g), since the user is within the 5 seconds and The handset is not held, so the processor 180 determines that the average value of the noise of the acceleration detected by the gravity sensor 150 within the 5 seconds is less than the noise threshold, and the processor 180 controls the other modules of the handset to operate in the power saving mode: That is, the processor 180 turns off the navigation application running in the background, the web browser, the photo application and the instant communication software, turns off the GPS module, and determines whether the music file is downloaded. If the download is completed, the WiFi module is closed, and if the music file is not downloaded, , continue to use the WiFi module to download music files. And the processor 180 records the identification of the closed application and the identification of the hardware module.

After half an hour, when the user picks up the mobile phone again and changes the state of the mobile phone to the state shown in FIG. 2a, FIG. 3a or FIG. 3b, the processor 180 determines that the power saving needs to be exited according to the result detected by the gravity sensor. In the mode, the processor 180 opens the navigation module, the web browser, the photographing application and the instant messaging software again according to the recorded identifier of the closed application and the identifier of the hardware module, and opens the GPS module. If the WiFi module is also turned off when entering the power saving mode, then the WiFi module is turned on again.

In the above embodiment, the display panel 141 displays an interface for setting the function of quickly entering the power saving mode, and receives an instruction that the user inputs the function of turning on the fast entry/exit power saving mode through the touch panel 131; the gravity sensor 150 detects the acceleration. (including acceleration on the X-axis, Y-axis, and Z-axis, noise of the overall acceleration); the processor 180 can determine the hand by judging the accelerations on the X-axis, the Y-axis, and the Z-axis. Whether the machine 100 is placed substantially horizontally in the downward direction of the touch panel 131, and a judgment of a duration of 5 seconds is added to reduce erroneous operation. The processor 180 can determine whether the mobile phone 100 is placed on a stationary object by the noise of the overall acceleration within the 5 seconds instead of being held in the user's hand. Only when the processor 180 determines that the mobile phone 100 is placed substantially horizontally in the downward direction of the touch panel 131 and is placed on a stationary object instead of being held in the user's hand, the user generally does not want to use the mobile phone, or is not in a hurry. The handset is used to receive and reply to the message, in which case the processor 180 controls the handset to enter a power save mode. When the gravity sensor detects that the state of the mobile phone 100 has changed, such as being picked up by the user, or the user flips the mobile phone such that the touch panel 131 is not facing substantially horizontally, the processor 180 no longer waits for a while, and immediately Controls the phone's power save mode to return to normal mode.

The foregoing embodiment provides a method for saving power, so that the mobile terminal can enter the power saving mode and exit the power saving mode according to the simple operation of the user, simplify the operation of the user, and improve the ease of use and interaction with the user of the mobile terminal. ability.

As shown in FIG. 6, the embodiment of the present invention provides a flowchart of a method for entering a power saving mode. The method is performed by the handset as shown in FIG. 1, and before the method is executed, the handset is in the normal mode, and the user has turned on or does not turn on the function of quickly entering the power saving mode. The method includes:

601. The processor 180 determines whether the function of quickly entering the power saving mode has been turned on. If the user has already displayed the function of setting the fast power saving mode on the display panel 141 before 601, the touch panel 131 is adopted. If the function of turning on the fast power saving mode is selected, execution 602 is performed. If the processor 180 determines that the function of quickly entering the power saving mode is not enabled, then 607 is performed.

602. The processor 180 determines whether the acceleration on the Z axis detected by the gravity sensor 150 is negative. If yes, execute 603. If not, execute 606.

It can be understood that before 602, the gravity sensor 150 is in an active state, and the X axis can be detected. The acceleration on the Y and Z axes, as well as the noise of the overall acceleration; if the gravity sensor 150 is not in operation, the processor 180 turns the gravity sensor 150 into an active state before performing 602.

603. The processor 180 determines whether the accelerations on the X-axis and the Y-axis detected by the gravity sensor 150 are substantially 0. If yes, execute 604. If not, execute 606.

Here, it is judged whether the acceleration on the X-axis and the Y-axis is substantially 0 in order to consider the case where the tabletop or other support for placing the mobile phone is not completely horizontal. A range of approximately 0 may be a value falling within the following range: (-0.98, 0.98), or (-0.49, 0.49), etc., wherein the unit of the numerical value in the interval is m/s2. The value of the interval can be set by the user or preset by the mobile phone manufacturer at the factory.

604. The processor 180 determines whether the noise of the acceleration detected by the gravity sensor 150 is less than a noise threshold (here set to 0.004 g). If the noise threshold is less than the noise threshold, perform 605. If not less than the noise threshold, Execute 606.

The noise of the acceleration as shown in FIGS. 4 and 5 is the noise of the overall acceleration detected by the gravity sensor 150, and is not the components on the X-axis, the Y-axis, and the Z-axis.

605. The processor 180 controls the mobile phone to enter a power saving mode.

The power saving mode in 605 is a normal power saving mode, and 605 includes: the processor 180 turns off all running processes of the background running application, stops the GPS, stops the earphone detection, stops the indicator light, stops the USB plug detection, and stops. NFC, stop voice wake-up, stop touch screen wake-up function, etc., but keep the answering call function on continuously. 605 further includes the processor 180 determining whether the RF circuit or the WiFi module is downloading the file. If not, the processor turns off the RF circuit and the WiFi module. If a file is being downloaded, the processor keeps the RF circuit or the WiFi module to continue downloading.

606. The processor 180 maintains the mobile phone operating in an existing mode.

After 606, 602 may be performed again until entering a power saving mode or the fast entering power saving mode The function is turned off.

607. The processor 180 maintains the mobile phone operating in an existing mode. After 607, 601 can be executed again.

Since the handset operates in the normal mode before the function of quickly entering the power saving mode is turned on, the existing mode in 606 and 607 is the normal mode.

It can be understood that 602 is for determining whether the display panel 140 (or the touch panel 131) is facing downward, and 603 is for determining whether the display panel 140 (or the touch panel 131) is horizontal, and 604 is for determining whether the mobile phone is placed on a stationary object. Without being held by the user, the execution order of the three steps can be interchanged. Only the judgment result of the three steps is YES, and 605 is executed. If the judgment result of one step is no, 606 is executed.

In order to reduce the error of the judgment, 602 may be replaced with the processor 180 determining whether the acceleration on the Z-axis detected by the gravity sensor 150 is approximately -1 g (ie, -9.8 m/s ² ), and if so, executing 603, If no, execute 606. The acceleration on the Z-axis is approximately -1 g, which means that the acceleration on the Z-axis is between -1.2 g and 0.98 g, and may be a value of other intervals, which is not limited in the present invention. When the acceleration on the Z-axis detected by the gravity sensor 150 is about -1 g, it indicates that the display panel 140 (or the touch panel 131) faces downward and is stationary relative to the ground or moving at a constant speed in the horizontal direction.

However, in actual life, if the mobile phone moves in a horizontal direction, such as a mobile phone placed on a seat or a table in a moving car or other moving vehicle, the gravity sensor of the mobile phone is affected by the car or other means of transportation. The noise of the detected acceleration is generally greater than 0.004 g. Therefore, if the noise of the acceleration is less than 0.004 g, the mobile phone generally does not move at a uniform speed in the horizontal direction.

Optionally, after 604, it can be determined whether the mobile phone is placed on a stationary object, that is, whether the mobile phone is stationary in the horizontal direction. For this reason, the acceleration sensor and the gyroscope can be used to obtain the acceleration of the mobile phone in the horizontal direction, and the mobile phone is judged accordingly. Whether it is still in the horizontal direction, or use GPS mode The block records the movement of the mobile phone to determine whether the mobile phone is moving, or uses the positioning function of the base station to determine whether the mobile phone is moving. There are various ways to determine whether the mobile phone moves in the horizontal direction in the prior art, which is not limited by the present invention. 605 is performed only when the handset is placed on a stationary object, otherwise 606 is performed.

In order to reduce the error of the judgment, it is also possible to increase the judgment of the duration in at least one of 602, 603 and 604. 602 can be replaced with 602': processor 180 determines if the acceleration on the Z-axis detected by gravity sensor 150 is negative for the first duration. 603 may be replaced by 603': processor 180 determines whether the accelerations on the X-axis and the Y-axis detected by gravity sensor 150 are substantially zero in the first duration. 604 may be replaced by 604': processor 180 determines gravity sensor Whether the noise of the detected acceleration is less than the noise threshold for the second duration, or the processor 180 determines whether the average of the noise of the acceleration detected by the gravity sensor 150 for the second duration is less than the noise gate Limit.

If the mobile phone 100 has entered the normal power saving mode before executing 601, it can be further determined by the judgment of 602, 603, and 604 whether the mobile phone 100 enters the super power saving mode, that is, 605 is replaced by: the processor 180 controls the mobile phone to enter the super power saving mode. mode. The content and order of the other steps remain the same and will not be repeated here.

In order to improve the accuracy of the judgment, after the determination results of 602, 603 and 604 are all YES, the judgment of the infrared sensor is increased, and the material of the object currently placed by the mobile phone 100 is determined according to the wavelength detected by the infrared sensor, if the current judgment is If the object on which the mobile phone is placed is wood or glass, the mobile phone is currently likely to be placed on the table in the downward direction of the display panel 140 (or the touch panel 131), and 605 is performed at this time. If it is judged that the object currently placed on the mobile phone is cloth or leather, the mobile phone is likely to be placed on the sofa or the bed in the downward direction of the display panel 140 (or the touch panel 131), which may be an unintended operation of the user. , not for the time being, do not use the phone, at this time execute 606.

It can be understood that 602 and 603 are for determining whether the mobile phone is placed horizontally in the downward direction of the display panel 140 (or the touch panel 131). The determination may also be implemented by other means, such as by a gyroscope or other sensor; whether the mobile phone is placed in the downward direction and horizontal direction of the display panel 140 (or the touch panel 131). If yes, execute 604, if not, then Execute 606.

In the above embodiment, if the processor of the mobile phone includes an application processor and a microcontroller, 601, 605, 606, and 607 are executed by the application processor, and 602, 603, and 604 are executed by the MCU, because the power consumption of the MCU is smaller than the application processing. The device is small, so it can achieve more power-saving technical effects.

The embodiment of the invention further provides a method for exiting the power saving mode. As shown in FIG. 7, the method is performed by the mobile phone as shown in FIG. 1, and before the method is executed, the mobile phone is in the power saving mode, and the user has turned on or does not turn on the function of quickly exiting the power saving mode. The method includes:

701. The processor 180 determines whether the function of quickly exiting the power saving mode has been turned on. If the user has already displayed the function for setting the quick exit power saving mode displayed on the display panel 141 before 701, the fast is selected to be turned on. When the function of the power saving mode is exited, 702 is executed. If the processor 180 determines that the function of quickly exiting the power saving mode is not enabled, then 707 is performed.

702. The processor 180 determines whether the acceleration on the Z axis detected by the gravity sensor 150 is positive. If not, execute 703. If yes, execute 706.

It can be understood that before 702, the gravity sensor 150 is still in operation (including when the mobile phone is in the power saving mode), can detect the acceleration on the X axis, the Y axis and the Z axis, and the overall acceleration; if the gravity sensor 150 is not in In the working state, the processor 180 turns on the gravity sensor 150 to be in an active state before executing 702.

703. The processor 180 determines whether the accelerations on the X-axis and the Y-axis detected by the gravity sensor 150 are far greater than 0. If not, execute 704, and if yes, perform 706.

Here, it is judged whether the acceleration on the X-axis and the Y-axis is much larger than 0, in order to consider for placing the hand. The desktop or other support of the machine is not completely horizontal. Far greater than 0 means greater than 0.98, or less than -0.98. Far greater than 0 can also mean greater than 0.49, or less than -0.49. Wherein, the unit of the above numerical value is m/s2.

704. The processor 180 determines whether the noise of the acceleration detected by the gravity sensor 150 is greater than a noise threshold (here set to 0.004 g). If the noise threshold is greater than the noise threshold, perform 705. If the noise threshold is less than the noise threshold, execute 705. 706.

The accelerations shown in FIGS. 4 and 5 are noises of the overall acceleration detected by the gravity sensor 150, and are not components on the X-axis, the Y-axis, and the Z-axis.

705. The processor 180 controls the mobile phone to work in a power saving mode.

706. The processor 180 controls the mobile phone to exit the power saving mode.

The exiting the power saving mode in 706 includes: all or part of the software functions and hardware modules that are turned off when the processor 180 starts to enter the power saving mode; or: the processor 180 starts the preset software functions and hardware modules, such as various types commonly used by the user. Software features and hardware modules.

After 705, 702 may be performed again until the handset exits the power save mode, or until the function of quickly exiting the power save mode is turned off.

707. The processor 180 maintains the mobile phone in a power saving mode. After 707, 701 can be executed again.

It can be understood that 702 is for determining whether the display panel 140 (or the touch panel 131) is facing upward, and 703 is for determining whether the display panel 140 (or the touch panel 131) is horizontal, and 704 is for determining whether the mobile phone is placed on a stationary object. Instead of being held in the hands of the user, the execution order of the three steps can be interchanged, and only the judgment result of the three steps is no, the execution 705 is performed, and if the judgment result of one step is YES, 706 is executed.

In order to reduce the error of the judgment, it is also possible to increase the judgment of the duration in at least one of 702, 703 and 704. 702 can be replaced with 702': processor 180 determines whether the acceleration on the Z-axis detected by gravity sensor 150 is positive for the first duration. 703 can be replaced by 703': processor 180 Whether the acceleration on the X-axis and the Y-axis detected by the broken gravity sensor 150 is much greater than 0 in the first duration. 704 may be replaced by 704': the processor 180 determines whether the acceleration detected by the gravity sensor 150 is in the second duration. It is greater than the noise threshold.

In the above embodiment, if the processor of the mobile phone includes an application processor and a microcontroller, 701, 705, 706, and 707 are executed by the application processor, and 702, 703, and 704 are executed by the MCU, because the power consumption of the MCU is smaller than the application processing. The device is small, so it can achieve more power-saving technical effects.

In this embodiment, if the determination result of 701 is YES, and the mobile phone maintains the state as shown in FIG. 2b, the mobile phone maintains the power saving mode after the judgment of 702, 703, and 704; if the determination result of 701 is YES, the mobile phone from the figure The state shown in 2b is switched to the state shown in Fig. 2a, Fig. 3a, and even Fig. 3b, and the cell is switched from the power saving mode to the normal mode after the judgment of 702, 703 and 704.

It can be understood that the above 602 and 702 are for determining whether the mobile phone is placed in the downward direction of the display panel 140 (or the touch panel 131). The determination can also be implemented by other means, such as by pressure sensors, infrared sensors and other sensors, the specific method is shown in Figure 8-11.

As follows, FIGS. 8 and 9 are diagrams in which a pressure sensor is used to determine whether or not the mobile phone is placed in the downward direction of the display panel 140 (or the touch panel 131).

As shown in FIG. 8, the embodiment of the present invention provides another method for entering a power saving mode. The method is performed by the handset as shown in FIG. 1, and before the method is executed, the handset is in the normal mode, and the user has turned on or does not turn on the function of quickly entering the power saving mode. The method includes:

801, the same as 601.

802. The processor 180 determines whether the pressure detected by the pressure sensor located on the back of the mobile phone 100 is less than a pressure threshold. If yes, execute 803. If not, execute 806.

Before 802, the pressure sensor 151 is still in operation (including when the mobile phone is in the power saving mode), and the pressure value can be detected; if the pressure sensor 151 is not in the working state, the processor 180 is Before performing 802, the pressure sensor 151 is turned on to make it in operation. Taking into account the error of the measurement, the pressure threshold can be set to a value close to 0, such as 0.1 Newton or 0.05 Newton.

803-807 are the same as 603-607, respectively, and the descriptions of 601, 603-607 are also applicable to 801, 803-807, respectively, and will not be repeated here.

Another embodiment of the present invention provides a method for exiting the power saving mode. As shown in FIG. 9, the method is performed by the mobile phone as shown in FIG. 1, and before the method is executed, the mobile phone is in the power saving mode, and the user has turned on or does not turn on the function of quickly exiting the power saving mode. The method includes:

901, the same as 701.

The description of the pressure threshold and the operating state of the pressure sensor 151 in 802 also applies to 902, and will not be repeated here.

903-907 are the same as 703-707, respectively, and the descriptions of 701, 703-707 are also applicable to 901, 903-907, respectively, and will not be repeated here.

As shown below, the infrared sensor is used to determine whether the mobile phone is placed in the downward direction of the display panel 140 (or the touch panel 131).

As shown in FIG. 10, the embodiment of the present invention provides another method for entering a power saving mode. The method is performed by the handset as shown in FIG. 1, and before the method is executed, the handset is in the normal mode, and the user has turned on or does not turn on the function of quickly entering the power saving mode. The method includes:

1001, the same as 601.

1002: The processor 180 determines whether the reflected energy detected by the infrared sensor located on the front side of the mobile phone 100 is greater than an energy threshold. If yes, execute 1003. If not, execute 1006.

The energy threshold can be close to the total energy of the infrared wave emitted by the infrared emitter, such as the total energy 90% or other value. Before 1002, the infrared sensor is still in working state (including when the mobile phone is in the power saving mode), and the reflected energy can be detected; if the infrared sensor is not in the working state, the processor 180 turns on the infrared sensor to make it before executing 1002. Working status.

1003-1006 is the same as 603-607, and the descriptions of 601, 603-607 are also applicable to 1001, 1003-1007, respectively, and will not be repeated here.

It should be noted that, by the judgment of 1002, only the front side of the mobile phone 100 can be judged whether there is occlusion, and it is not possible to completely judge whether the front side is facing downward. After the determination of 1002 is YES, before 1003 is performed, 1002a is added: the processor 180 determines that the mobile phone is located at the mobile phone. The reflection wavelength detected by the front side infrared sensor is glass or wood, and if so, 1003 is performed, and if not, 1006 is performed. Since the front surface of the mobile phone 100 is covered by glass or wood, usually when the mobile phone is placed down on the desktop, or the user is inconvenient to view the display panel 141 and operate the touch panel 131, in this case, the user usually does not want to The case of using the mobile phone 100.

As shown in FIG. 11, the embodiment of the present invention provides another method for exiting the power saving mode. The method is performed by a mobile phone as shown in FIG. 1, and before the method is executed, the mobile phone is in a power saving mode, and the user has turned on or does not turn on the function of quickly exiting the power saving mode. The method includes:

1101, the same as 701.

1102. The processor 180 determines whether the reflected energy detected by the infrared sensor located on the front of the mobile phone 100 is less than an energy threshold. If not, executing 903, and if yes, executing 906.

The description of the energy threshold and the operating state of the infrared sensor in 1002 also applies to 1102, which is not repeated here.

1103-1107 is the same as 703-707, and the descriptions of 701, 703-707 are also applicable to 1101, 1103-1107, respectively, and will not be repeated here.

Similarly, it can be judged by the judgment of 1102 whether the front side of the mobile phone 100 is occluded or not. If it is judged whether the front side is facing down, after 1102 is judged to be no, before performing 1103, 1003a is added: the processor 180 determines whether the reflected wavelength detected by the infrared sensor located on the front side of the mobile phone 100 is glass or wood, and if yes, executes 1103. If no, execute 1106. Since the front surface of the mobile phone 100 is covered by glass or wood, usually when the mobile phone is placed down on the desktop, or the user is inconvenient to view the display panel 141 and operate the touch panel 131, in this case, the user usually does not want to The case of using the mobile phone 100.

The method of entering the power saving mode and the method of exiting the power saving mode as described above can be used together. When the method shown in any one of FIG. 6, FIG. 8 and FIG. 10 is used, after the mobile phone enters the power saving mode, the method shown in any one of FIG. 7, FIG. 9 and FIG. 11 can be used to cause the mobile phone to exit the power saving mode. . Conversely, after using the method shown in any one of FIG. 7, FIG. 9 and FIG. 11 to make the mobile phone exit the power saving mode, the method shown in any one of FIG. 6, FIG. 8 and FIG. 10 can also be used to make the mobile phone enter the province.
