The location information module 115 is a module for confirming or obtaining the location of the mobile terminal. The location information module 115 may obtain location information by using a global navigation satellite system (GNSS), a cell ID method, and a wireless LAN (LAN) access location sensing method. Hereinafter, the position information module 115 divides each method for acquiring position information.

First, the location information module 115 may obtain location information using a global navigation satellite system (GNSS). Here, the Global Positioning System (GNSS) is a term used to describe the radionavigation satellite systems that revolve the Earth and send reference signals that allow certain types of radionavigation receivers to determine their position near the surface or ground surface to be. The Global Positioning System (GNSS) includes Global Positioning System (GPS) in the United States, Galileo in Europe, GLONASS (Global Orbiting Navigational Satelite System) in Russia, COMPASS in China and Japan QZSS (Quasi-Zenith Satellite System), which is operated by the Ministry of Land, Infrastructure and Transport.

As a representative example of the GNSS, the location information module 115 may be a Global Position System (GPS) module.

Second, the location information module 115 may obtain location information using a cell-ID method. The cell-ID scheme uses a plurality of base stations 200 of a wireless communication system (for example, see FIG. 5A). A typical example of the wireless communication system is a mobile communication system based on a CDMA, GSM, or WCDMA communication system. The location information can be obtained by using the identification information (for example, the base station ID) of one or more base stations 200 corresponding to the location of the mobile terminal 100 and the signal strength information received from each base station. The cell ID scheme can be more precisely located using a triangulation scheme using one or two base stations and three base stations.

The microphone 122 receives an external sound signal through a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output. Various noise reduction algorithms may be implemented in the microphone 122 to remove noise generated in receiving an external sound signal.

The user input unit 130 may include a key pad dome switch, a touch pad (static / static), a jog wheel, a jog switch, and the like. The sensing unit 140 senses the current state of the mobile terminal 100 such as the open / close state of the mobile terminal 100, the position of the mobile terminal 100, the presence or absence of user contact, the orientation of the mobile terminal, And generates a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. In addition, it may be responsible for a sensing function related to whether the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like. Meanwhile, the sensing unit 140 may include a proximity sensor 141.

The output unit 150 is for generating output related to the visual, auditory or tactile sense and includes a display unit 151, an audio output module 152, an alarm unit 153, and a haptic module 154 .

The display unit 151 displays and outputs information processed by the mobile terminal 100. For example, when the mobile terminal is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. When the mobile terminal 100 is in the video communication mode or the photographing mode, the photographed and / or received video or UI and GUI are displayed.

With this structure, the user can see an object located behind the terminal body through the area occupied by the display unit 151 of the terminal body.

There may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, in the mobile terminal 100, a plurality of display portions may be spaced apart from one another or may be disposed integrally with each other, or may be disposed on different surfaces.

The display unit 151 is connected to a display unit 151 and a sensor for sensing a touch operation (hereinafter, referred to as 'touch sensor') having a mutual layer structure It can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the pressure at the time of touch.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays. The proximity sensor has a longer life span than the contact sensor and its utilization is also high. Examples of the proximity sensor include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

And to detect the proximity of the pointer by the change of the electric field along the proximity of the pointer when the touch screen is electrostatic. In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

The audio output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory unit 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output module 152 outputs an acoustic signal related to a function (e.g., a call signal reception sound, a message reception sound, etc.) performed in the mobile terminal 100. The audio output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal can also be output through the display unit 151 or the audio output module 152.

The haptic module 154 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 154 is vibration. The intensity and pattern of the vibration generated by the hit module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output. In addition to the vibration, the haptic module 154 may be configured to perform various functions such as an effect of stimulation by a pin arrangement vertically moving with respect to a contact skin surface, an effect of stimulation by air spraying force or suction force through a jet opening or a suction opening, A variety of tactile effects such as an effect of stimulation through contact of an electrode, an effect of stimulation by an electrostatic force, and an effect of reproducing a cold sensation using a heat absorbing or exothermic element can be generated.

The haptic module 154 can be implemented not only to transmit the tactile effect through the direct contact but also to feel the tactile effect through the muscles of the user's finger or arm. The haptic module 154 may include two or more haptic modules 154 according to the configuration of the portable terminal 100.

The memory unit 160 may store a program for the operation of the controller 180 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory unit 160 may store data related to vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory unit 160 may be a flash memory type, a hard disk type

The mobile terminal 100 may operate in association with a web storage that performs a storage function of the memory unit 160 on the Internet.

The interface unit 170 serves as a path for communication with all external devices connected to the mobile terminal 100. The interface unit 170 receives data from an external device or receives power from the external device to transfer the data to each component in the mobile terminal 100 or to transmit data in the mobile terminal 100 to an external device. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, A video input / output (I / O) port, an earphone port, and the like may be included in the interface unit 170.

FIG. 2 is a flowchart illustrating an operation of a mobile terminal according to an exemplary embodiment of the present invention, and FIG. 3 is a diagram illustrating a mobile terminal according to FIG.

As shown in these drawings, the mobile terminal 100 according to an embodiment of the present invention may include a step S10 of checking the remaining amount of the battery.

The mobile terminal 100 is generally supplied with power through a battery because of its inherent portability. That is, the mobile terminal 100 is provided with a battery, discharging the battery, and supplying power to the mobile terminal 100. Since the battery discharges electricity by supplying power to the mobile terminal 100, the user must repeatedly recharge the battery periodically.

The mobile terminal 100 according to an embodiment of the present invention can check the remaining amount of the battery at regular intervals. For example, it may be possible to check the remaining amount of the battery based on time, such as once a minute, once every five minutes, and so on.

The step S20 of checking the currently running application may be performed.

If the power is supplied and available, the mobile terminal 100 may be considered to be running a specific application. That is, in order for the mobile terminal 100 to operate normally, an appropriate operating system (OS) must be operated. OS is also a kind of application. In addition, when the call function is being performed, the call application is being executed. If the sound source file playback function is being performed, the sound source playback application is being executed.

If the currently running application is checked, step S30 of determining the battery display method may be performed.

The battery indication method may vary depending on the type of application currently being executed. That is, it means that the method of displaying the remaining amount of the battery on the user can be displayed differently depending on the application. For example, in the case where the remaining amount of the battery is 50%, the fact that 50% of the first application is being executed can be displayed as it is, and only 30% is remaining if the second application is being executed As shown in FIG.

The display method of the battery may vary depending on the application. Accordingly, it is possible to determine how to display the battery on the display unit 151 on the basis of the currently executed application information obtained through step S20.

When the battery display method is determined, step S40 of displaying the battery remaining amount may be performed according to the determined display method.

In step S50, it is possible to display the battery remaining amount optimized for the currently running application according to the determined display method, and to determine whether or not the available remaining battery capacity is available.

Of the respective applications of the mobile terminal 100, the magnitude of the appropriate voltage required to execute the call function may be greater than the magnitude of the voltage required for execution of the other application. For example, in comparison with a voltage required for operation of a sound source file playing application that simply loads a music file and reproduces through an earphone, the microphone (the numeral 122 in FIG. 1) transmits / And the voltage required for operation of the communication application in which the sound output module 152 operates are higher. Although the mobile terminal 100 has various applications that can be operated, the function most faithful to the function of the mobile terminal 100 may be a call function. Therefore, the mobile terminal 100 according to an embodiment of the present invention can determine whether the remaining battery level is sufficient to execute the call function, based on the voltage at which the call function can be executed.

When the remaining amount of the battery can not reach the talkable level, step S60 for terminating another application being executed and step S70 for entering the call standby mode may be performed.

The other application in execution means an application excluding an application for a call function. It is possible to stably maintain the call function, which is an essential function of the mobile terminal 100, by terminating other applications that are running when the battery remaining amount can not reach the talkable level. Furthermore, by terminating other applications and entering the call standby mode, the call function can be maintained more reliably.

3, a battery indicator BR may be displayed on the display unit 151 of the mobile terminal 100 according to an exemplary embodiment of the present invention.

Since the battery indicator BR is displayed on the display unit 151, the user can easily recognize the current charge amount charged in the battery of the mobile terminal 100. The battery indicator BR may include several cell indications. The cell indicated by the battery indicator BR may indicate the current battery charge state. That is, when the battery is almost fully charged, it may be indicated that the cell is fully charged, and when the battery is close to the discharge, the cell may be indicated as being completely empty. The state where the cell is completely empty while the cells are all filled can be progressed sequentially as the battery is used. The display method of the cell according to the remaining battery level will be described more specifically in the corresponding part.

4 is a diagram showing power consumption according to an application.

As shown, the amount of power required to operate various applications of the mobile terminal 100 according to an embodiment of the present invention may be different. For example, MP3 players that play MP3 files can work well in relatively low power situations. On the other hand, in order for the wireless Internet function used by the wireless communication unit 110 to operate normally, a higher power may be required in the case of the MP3 player. In addition, the call function using the wireless communication unit 110, the microphone 122, and the sound output module 152 may require higher power than the wireless Internet function. As such, the amount of power required for normal operation of each application in the mobile terminal 100 may be different, and in particular, the call function may require relatively high power.

FIG. 5 is a diagram illustrating the battery remaining amount with time of the mobile terminal of FIG. 2;

As shown, the battery of the mobile terminal 100 according to the embodiment of the present invention may change the charged amount BL as the mobile terminal 100 is used. That is, in the full charge (M) state, the power of the battery can exhibit the highest numerical value. However, when the mobile terminal 100 is used, the battery can be discharged. As the battery discharges, the remaining amount of the battery may also be reduced. When the remaining amount of the battery is reduced without recharging, the battery remaining amount may reach the call threshold power (L).

The call threshold power L may mean the minimum power state at which the call function can be smoothly performed. If the remaining amount of the battery is lower than the call threshold power L, the call may not be normally performed. Therefore, in order to normally maintain the call function, which is an essential function of the mobile terminal 100, it is necessary to keep the remaining amount of the battery equal to or above the call threshold power L.

FIG. 6 is a view showing a battery display according to the battery remaining amount chart of FIG. 5; FIG.

As shown in the figure, the mobile terminal 100 according to an embodiment of the present invention can change the display of the battery indicator BR so as to correspond to the charged amount BL of the battery.

The battery indicator BR may include first, second, and third cells C1, C2, and C3. The first, second, and third cells (C1, C2, and C3) may be displayed as being filled or emptied depending on the remaining amount of the battery, as described above.

The first to third intervals R1 to R3 may be divided into three periods which are equally divided between the full charge M and the call threshold power L,

When the remaining amount of the battery is within the first range R1, the first to third cells C1 to C3 included in the battery indicator BR may be displayed in a full state. Therefore, it can be recognized that the user can use the mobile terminal 100 for a considerable time or longer since the battery is currently fully charged or fully charged.

When the remaining amount of the battery is in the second range R2, the first cell C1 of the battery indicator BR is marked as emptied and the second and third cells C2 and C3 are filled . In addition, when the remaining battery level is within the third range R3, only the first cell C1 of the battery indicator BR can be displayed as filled.

When the battery remaining amount is equal to or less than the call threshold power L, it is indicated that all of the cells C1 to C3 of the battery indicator BR have been emptied or that the battery indicator BR having been emptied of each of the cells C1 to C3 is blinking can do. Therefore, the user can expect that the battery of the mobile terminal 100 will be discharged when the normal call is not available or the call function is executed for a very short time.

FIG. 7 is a view showing a display range according to the application of the remaining battery level of FIG. 5; FIG.

As shown, the charged amount BL of the battery can be divided into different ranges.

The left vertical axis of the chart divides the remaining amount of the battery with the currency threshold power (L) or more in the first to third ranges (R1 to R3). In addition, the right vertical axis of the chart divides the battery remaining amount equal to or more than the call threshold power (L) into the fourth to seventh ranges (R4 ratios R7). That is, with respect to the battery remaining amount equal to or larger than the call threshold power L, the left vertical axis in the chart is divided into three sections, and the right vertical axis in the chart is divided into four sections.

Since the same range from full charge (M) to call threshold power (L) is divided into three or four sections, the width of the range may vary. That is, the A-B time, which is the usage time corresponding to the R1 section, can be longer than the A-a time under the same use condition. The display of the battery indicator BR may vary depending on the ranges R1 to R7. Hereinafter, the case where the display of the battery indicator BR changes according to the type of the application being executed will be described in more detail according to the related drawings.

FIG. 8 and FIG. 9 are diagrams illustrating a method of displaying remaining battery power according to an application.

As shown in the figure, the remaining amount of the battery displayed on the battery indicator BR can be displayed differently depending on the currently executed application. For example, the display of the battery indicator BR may be different when the current call function is being executed and when the current MP3 player function is being executed. Accordingly, it is possible to prevent a situation in which the call function of the mobile terminal 100 is not executed because the user excessively uses the battery to execute the non-essential additional function of the mobile terminal 100.

As shown in FIG. 8, the battery indicator BR is gradually emptied as the remaining amount of the battery gradually decreases from the first section R1 to the third section R3. When the remaining amount of the battery is equal to or less than the third section R3, the battery indicator BR which is completely empty can be displayed or the battery indicator BR which flickers at a predetermined period can be displayed. Furthermore, the flashing battery indicator BR may flash more rapidly as the remaining battery power is reduced.

As shown in FIG. 9, the battery indicator BR is gradually emptied as the remaining amount of the battery gradually decreases from the fourth section R4 to the sixth section R6, as shown in FIG. 8 And is the same as that of the battery indicator BR. However, as shown in Fig. 7, the widths of the fourth section R4 to the sixth section R6 are narrower than the first section R1 to the third section R3. Accordingly, the battery indicator BR corresponding to the fourth to sixth sections R4 to R6 may be emptied sooner.

The battery indicator BR corresponding to the first to third sections R1 to R3 and the battery corresponding to the fourth to sixth sections R4 to R6 are different from each other Can be seen. That is, when the remaining amount of the battery is between the fourth section R4 and the first section R1, the battery indicator BR corresponding to the first to third sections R1 to R3 is filled with batteries Can be displayed. However, in the case of the battery indicator BR corresponding to the fourth to sixth sections R4 to R6, one cell may be marked as empty. A battery indicator BR corresponding to the first to third sections R1 to R3 is displayed when the communication function is executed and a battery indicator BR corresponding to the fourth to sixth sections R4 to R6 is displayed when another function is executed. Indicating the indicator (BR), a user using other functions may expect to be more sensitive to battery consumption. Therefore, it is possible to prevent the battery from being discharged to such an extent that the mobile terminal 100 can not execute the call function.

When the remaining amount of the battery reaches the seventh section R7, execution of the function can be stopped. And the seventh section R7 is close to the call threshold power (L). Therefore, it is possible to prevent a situation in which a call, which is an essential function of the mobile terminal 100, becomes impossible due to the use of another function. This will be described more specifically in the corresponding portions.

10 is a view showing the display range of the remaining battery level of the application shown in Fig.

As shown in the figure, the range indicated by one cell of the battery indicator BR can be set differently for each application.

10 (a) shows the battery indicator BR1 for the call function, and FIG. 10 (b) shows the battery indicator BR2 for the other functions. As shown in the figure, the battery indicator BR1 for the call function and the battery indicator BR2 for the other functions may be visually identical in shape at a specific point in time. However, the range corresponding to one cell of the battery indicator (BR1) for the call function and the range corresponding to one car of the battery indicator (BR2) for other functions may be different. That is, it means that the absolute values of R1, R2 and R3 can be larger than the absolute values of R4, R5 and R6 as shown in FIG. 10 (c). Therefore, the display of the battery indicator BR2 for the other functions can be changed more quickly than the battery indicator BR1 for the call function.

FIG. 11 is a diagram illustrating a method of displaying the battery remaining amount for each application of the mobile terminal according to FIG.

As shown, different battery indicators BR may be displayed depending on the type of application being executed in the mobile terminal 100 according to an embodiment of the present invention.

As shown in Fig. 11A, the mobile terminal 100 may be executing an MP3 player function (MP) for playing an MP3 file. At this time, the battery indicator BR2 for other functions may be displayed as the battery indicator BR. The control unit (180 in FIG. 1) of the mobile terminal 100 may check the remaining battery level from time to time to change the display of the battery indicator BR2 for other functions.

As a result of checking the remaining amount of the battery at a specific point in time, there may be a case where the first to third cells (C1 to C3) of the other function battery indicator BR2 are marked as being empty. Since the battery indicator BR2 for the other functions is empty, the user can easily recognize that the battery is short. Therefore, the execution of the MP3 player function (MP) can be stopped spontaneously.

As shown in FIG. 11 (b), the mobile terminal 100 may be executing the call function (CC). At this time, it can be indicated that the first cell C1 of the battery indicator BR1 for the call function is filled as the battery indicator BR.

11 (a) and 11 (b), the remaining battery level may be the same. The battery indicator BR1 for the call function and the battery indicator BR2 for the other functions may be displayed differently even though the battery remaining amount is substantially the same. That is, when the user executing the MP3 player function MP switches the function and executes the call function (CC), the battery indicator BR is switched and displayed to indicate that the display can be changed. That is, when the remaining battery level is less than a certain level, it is possible to suppress the use of a function other than the call function (CC) by the user.

FIG. 12 and FIG. 13 are diagrams illustrating operations of the mobile terminal according to FIG. 2 according to the remaining battery level.

As shown in these drawings, the mobile terminal 100 according to an embodiment of the present invention can forcibly terminate a specific function being executed in the mobile terminal 100 when the remaining battery level is below a certain level. In addition, the mobile terminal 100 according to an exemplary embodiment of the present invention can set whether to use the automatic termination function and specific functions to use the automatic termination function.

As shown in FIG. 12 (a), the mobile terminal 100 may be executing an MP3 player function (MP). When the MP3 player function MP is being executed, the battery indicator BR2 for the other functions may be displayed as the battery indicator BR. On the other hand, at a specific point in time, the first to third cells (C1 to C3) of the battery indicator BR2 for other functions may all be in an empty state. In this state, when the battery remaining amount reaches the seventh section R7, the MP3 player function MP currently being executed can be forcibly terminated as shown in Fig. 12 (b). In addition, a pop-up window (P) indicating this fact can be displayed prior to forced termination of the MP3 player function (MP).

As shown in Fig. 13, the mobile terminal 100 can display a screen for setting the automatic termination function. The user can choose whether to use the automatic termination function and if so, which function to use the automatic termination function. That is, it means that it is possible to prevent the automatic termination at the execution of a specific function according to the user's needs.

FIG. 14 is a diagram illustrating a method of displaying the remaining battery level of an application according to another embodiment of the present invention.

The mobile terminal 100 according to another embodiment of the present invention may display different types of battery indicators BR for each application.

As shown in FIG. 14 (a), the first to third cells (C1 to C3) can be displayed in the battery indicator for call function BR1. On the other hand, as shown in FIG. 14 (b), the first to fourth cells (C1 to C4) can be displayed in the battery indicator BR2 for other functions. The number of cells may be reversed or may differ from three or four.

FIG. 15 is a view showing a display range according to the application of the remaining battery level according to FIG.

The first to third sections R1 to R3 corresponding to the call function battery indicator BR1 are divided into three sections and the third to eighth sections R4 to R4 corresponding to the other function battery indicator BR2 are divided into three sections, R8) are divided into four sections. That is, it means that the battery indicator BR can be displayed differently depending on the type of the application being executed.

FIG. 16 is a view showing a display range according to an application of the remaining battery level according to still another embodiment of the present invention, and FIG. 17 is a diagram illustrating a remaining battery level display method according to FIG.

As shown in these drawings, the size of a section of a mobile terminal 100 according to an embodiment of the present invention may be different from that of another section.

16, among the first to third sections R1 to R3 corresponding to the battery indicator for call function BR1, the second section R2 is larger than the first and third sections R1 and R3 And corresponds to a large area. Among the fourth to seventh intervals R4 to R7 corresponding to the battery indicator BR2 for the other functions, the fifth interval R5 corresponds to a larger area than the other intervals.

As shown in Fig. 17A, each cell C1 to C3 of the battery indicator BR may have the same size of the area visually displayed. Also, as shown in Fig. 17B, the size of each cell (C1 to C3) region of the battery indicator BR may be different. The second cell C2 having a different size may correspond to the second section R2 of FIG. In such a case, in the second cell C2 region, the residual amount indication of the battery can be maintained longer than in the other cells C1 and C3.

FIG. 18 is a diagram illustrating a remaining battery level display method according to another embodiment of the present invention.

As shown, a voltage corresponding to the battery indicator BR may be displayed together with the battery indicator BR according to an embodiment of the present invention. In addition, the interval range of the displayed voltage may be different for each application.

18 (a) shows a battery indicator BR1 for the call function among the battery indicators BR. As shown in the figure, voltages corresponding to the first to third cells (C1 to C3) may be displayed together. On the other hand, the voltages indicated in the first to third cells (C1 to C3) are indicated at intervals of one volt.

FIG. 18 (b) shows the battery indicator BR2 for the other functions among the battery indicators BR. As shown in the figure, the first to third cells (C1 to C3) are each marked with a corresponding voltage, and the voltage is displayed at an interval of 0.5 volts. That is, it means that voltage intervals can be displayed differently for each application being executed. In addition, while the lowest value of the battery indicator BR1 for the call function is 1 volt, the battery indicator BR2 for the other functions may be 2.5 volts. This means that in the case of a function that is not a call function, when it becomes 2.5 volts or less, it is possible to enter a call standby mode in which a forced termination can be performed to execute the call function.

FIG. 19 is a diagram illustrating a remaining battery level display method according to another embodiment of the present invention; FIG. 20 is a diagram illustrating a mobile terminal according to FIG. 19;

As shown in these figures, the battery indicator BR according to the embodiment of the present invention can display the executable time BRT.

As shown in Figs. 19 (a) and 19 (b), the battery indicator BR may be displayed together with the executable time BRT. The executable time BRT can be calculated in the control unit (180 in Fig. 1) based on the type of the currently executed application and the current charging amount of the battery.

As shown in FIG. 20 (a), when the MP3 player MP is running, the battery indicator BR2 for other functions and the executable time BRT can be displayed. On the other hand, as shown in FIG. 20 (b), the call function CC is executed and in this case, the battery indicator BR1 for the call function and the executable time BRT can be displayed.

As described above, when the MP3 player MP is running and when the communication function CC is being executed, the scope of the display may be different. Therefore, the battery indicator BR2 for the other functions displayed while the MP3 player MP is running has a very small battery charge amount and the BRT is also displayed as 10 minutes. However, when the call function CC is executed The battery indicator (BR1) for the call function displayed while the battery is being charged is somewhat charged, and the execution time (BRT) is also displayed as 20 minutes. The battery indicator BR can be displayed differently according to the function, so that even if the amount of charge of the battery is small, other functions can be forcibly executed to prevent the use of the call function in advance.

In the above-described embodiments, the case where the inside of the battery indicator is partitioned into a plurality of cells has been mainly described. However, the display may continuously change according to the charged amount of the battery in a state where the inside of the battery indicator is not visually clearly divided. Of course.
