When user continues to hold, mobile phone front is directed downwardly to be continued to move to, and finally by mobile phone according to according to Fig. 2 b institute The touch panel 131 shown is directed downwardly to be placed in horizontal table top, and no longer contacts mobile phone.At this point, processor 180 first judges that the acceleration on Z axis that gravity sensor 150 detects is negative, and substantially -9.8m/s2Then processor 180 continues to judge the acceleration substantially 0 in X-axis and Y-axis that gravity sensor 150 detects, and then processor 180 judges the acceleration for the Z-direction that gravity sensor 150 detects, the acceleration above each substantially -9.8m/s whether for 5 seconds on acceleration and Y-axis in X-axis2, 0 and 0.If the judgment is Yes, processor 180 then judges whether the average value of the noise for the acceleration that gravity sensor 150 detects in above-mentioned 5 seconds is less than noise threshold (being set as 0.004g herein), since user does not hold the mobile phone in this 5 seconds, therefore processor 180 judges that the average value of the noise for the acceleration that gravity sensor 150 detects in this 5 seconds is less than the noise threshold, other modules that then processor 180 controls mobile phone work in battery saving mode: i.e. the navigation application of the closing of processor 180 running background, web browser, it takes pictures application and instant communication software, close GPS module, and judges whether music file is downloaded and finish, if downloading finishes, then close WiFi module, it is finished if the music file is not downloaded, then continue to use WiFi mould Block download music files.And the mark for the application that the record of processor 180 is closed and the mark of hardware module.
After in half an hour, when user picks up mobile phone again, the state of mobile phone is become such as Fig. 2 a, when state shown in Fig. 3 a or Fig. 3 b, then processor 180 is judged to need to exit battery saving mode according to the result that gravity sensor detects, then processor 180 is according to the mark of the application of the closing of record and the mark of hardware module, it is again turned on navigation application, web browser, take pictures application and instant communication software open GPS module.If WiFi module is also turned off, then opens WiFi module again at this time when entering battery saving mode.
In above-described embodiment, display panel 141 display setting this rapidly enter the interface of the function of battery saving mode, and receive user by touch panel 131 input open this rapidly enter/leave the instruction of the function of battery saving mode；Gravity sensor 150 detects acceleration (including X-axis, the acceleration in Y-axis and Z axis, the noise of whole acceleration)；Processor 180 is by judging that the acceleration on X-axis, Y-axis and Z axis may determine that hand Machine 100 whether according to 131 downward of touch panel approximate horizontal placement, and increase by 5 seconds duration judgement, to reduce maloperation.The processor 180 may determine that whether mobile phone 100 is placed on static object by the noise of the whole acceleration in described 5 seconds, rather than be held in user hand.Only when processor 180 judges mobile phone 100 according to the approximate horizontal placement of 131 downward of touch panel and is placed on static object, rather than when being held in user hand, user is generally not desired to using mobile phone at this time, or no hurry using mobile phone reception and replies message, in this case, the control of processor 180 mobile phone enters battery saving mode.When the gravity sensor detects that the state of mobile phone 100 changes, such as picked up by user, or user overturn mobile phone and make touch panel 131 not it is approximate horizontal downward, then processor 180 is no longer waiting for a period of time, and mobile phone battery saving mode is immediately controlled, to be restored to normal mode.
Above mentioned embodiment provide a kind of methods of power saving, allow mobile terminal to enter battery saving mode according to the simple operations of user and exit battery saving mode, simplify the operation of user, improve the ease for use of mobile terminal and the interaction capabilities with user.
As shown in fig. 6, the embodiment of the present invention provides a kind of method flow diagram into battery saving mode.This method is executed by mobile phone as shown in Figure 1, and before executing this method, mobile phone is in normal mode, and user has had turned on or do not opened the function of rapidly entering battery saving mode.This method comprises:
601, processor 180 judges that this rapidly enters whether the function of battery saving mode has been switched on, if user is used to be arranged in the interface of the function of rapidly entering battery saving mode before 601 what display panel 141 was shown, having selected unlatching by touch panel 131, this rapidly enters the function of battery saving mode, then execute 602, if processor 180 judges that this rapidly enters the function of battery saving mode and does not open, 607 are executed.
602, processor 180 judges whether the acceleration on Z axis that gravity sensor 150 detects is negative, if it is, 603 are executed, if it is not, then executing 606.
It is appreciated that gravity sensor 150 is in running order before 602, it is able to detect that X-axis, Acceleration in Y-axis and Z axis, and the noise of whole acceleration；If gravity sensor 150 is not on working condition, processor 180 first opens gravity sensor 150 and is at working condition before executing 602.
603, processor 180 judge the acceleration in X-axis and Y-axis that gravity sensor 150 detects whether substantially 0, if it is, 604 are executed, if it is not, then executing 606.
The acceleration judged in X-axis and Y-axis herein whether substantially 0, be to consider that desktop for placing mobile phone or other supporters are not fully horizontal situations.Substantially 0 range can be the value for falling into following section: (- 0.98,0.98), or (- 0.49,0.49) etc., wherein the unit of the numerical value in section is m/s2.The value in the section can be preset etc. when leaving the factory by user setting or by mobile phone producer.
604, processor 180 judges whether the noise for the acceleration that gravity sensor 150 detects is less than noise threshold (being set as 0.004g herein) and then executes 605 if it is less than noise threshold, if not being less than noise threshold, executes 606.
The noise of acceleration as shown in Figure 4 and Figure 5 is the noise for the whole acceleration that gravity sensor 150 detects, and the not component on X-axis, Y-axis and Z axis.
605, the control of processor 180 mobile phone enters battery saving mode.
Battery saving mode in 605 is common battery saving mode, 605 include: the process that processor 180 closes the application for all running backgrounds being currently running, stop GPS, stop headset detection, stop indicator light prompting, stopping USB plug detection, stop NFC, the wake-up of stopping voice, stop touch screen arousal function etc., but be to maintain and answer the lasting unlatching of call function.605 further include, and processor 180 judges whether RF circuit or WiFi module are downloading file, if it is not, then processor closes RF circuit and WiFi module, if there is file is being downloaded, then processor keeps RF circuit or WiFi module to continue to download.
606, processor 180 maintains operating handset in existing mode.
After 606,602 can be executed again, until enter battery saving mode or this rapidly enter power saving mould The function of formula is closed.
607, processor 180 maintains operating handset in existing mode.After 607,601 can be executed again.
Since before unlatching rapidly enters the function of battery saving mode, operating handset is in normal mode, therefore the existing mode in 606 and 607 is normal mode.
It is understood that, 602 be to whether downward judge display panel 140 (or touch panel 131), 603 be to judge whether display panel 140 (or touch panel 131) is horizontal, 604 be in order to judge whether mobile phone is placed on static object, without by user it is hand held in, the execution sequence of three steps can be interchanged, it is only all yes there are three the judging result of step, just execute 605, as long as the judging result for having a step be it is no, be carried out 606.
In order to reduce the error of judgement, 602 can also be replaced with whether the acceleration on the Z axis that processor 180 judges that gravity sensor 150 detects is about -1g (i.e. -9.8m/s2), if it is, 603 are executed, if it is not, then executing 606.Acceleration on Z axis is about that -1g refers to that the acceleration on Z axis between -1.2g to 0.98g, is also possible to the value in other sections, which is not limited by the present invention.When the acceleration on the Z axis that gravity sensor 150 detects is about -1g, then illustrate display panel 140 (or touch panel 131) downward, and opposite ground is static or uniform motion in the horizontal direction.
However, in actual life, if mobile phone moves in the horizontal direction, such as mobile phone is placed on the seat or desk in the automobile of traveling or the vehicles of other travelings, due to being influenced by automobile or other vehicles, the noise for the acceleration that the gravity sensor of mobile phone detects generally can also be greater than 0.004g, therefore, if the noise of acceleration is less than 0.004g, mobile phone is generally in the horizontal direction also without uniform motion.
Optionally, it can judge whether mobile phone is placed on static object after 604, judge whether mobile phone is static in the horizontal direction, thus, acceleration transducer can be used and gyroscope obtains mobile phone acceleration in the horizontal direction, and judge whether mobile phone is also static in the horizontal direction accordingly, or use GPS mould Whether the motion determination mobile phone of block record mobile phone moves, or judges whether mobile phone moves using the positioning function of base station, and in the prior art also there are many mode whether mobile phone move in the horizontal direction is judged, which is not limited by the present invention.Only when mobile phone is placed on static object, otherwise just execution 605 executes 606.
