Description
Technical field
The invention belongs to smart mobile phone technical field, be specifically related to a kind of method that reduces cell phone standby power consumption.
Background technology
Along with the rise of Android platform, smart mobile phone is more and more universal.People like having gone up this can free mounting software, realize the mobile phone of differentiation function.
But smart mobile phone is compared to traditional functional mobile phone, and having a significant shortcoming is that stand-by time is much shorter.Traditional functional mobile phone is under the normal condition of using, and general standby 4 ~ 5 days, and intelligent machine, generally can only standby 1 ~ 2 day, and major part is essential charging every day.
Smart mobile phone stand-by time is short, directly related with the software (application) that people install, some softwares are frequently done some periodic things by timer, such as: the version that access specific website, downloads ad resource, obtain up-to-date notification message, whether inspection is upgraded etc.These behaviors have caused the network traffics of mobile phone to increase and the increase of power consumption, serious shortening the stand-by time of mobile phone.
The application program that smart mobile phone is installed is more and more, when some are applied in running background, still by timer is set, continually self is waken up, application is waken up generally can do following thing afterwards: access specific website, downloads ad resource, obtain up-to-date notification message, check the version that whether upgrades etc.Mobile phone is cutting out screen while entering standby, and the modules such as APP CPU, Modem CPU and radio frequency are slept penetration depth, and electric quantity consumption is very low.But wake up to the timer high-frequency that they are arranged by numerous application programs, carry out different background tasks, cause power consumption very high, seriously shortened the stand-by time of mobile phone.
On the one hand timer is a critical function of mobile phone, and system and various program are delayed according to plan a period of time and done some things by timer is set; Program has very high required precision to the response time of timer, must guarantee to trigger of fixed place and timely.On the other hand, certain applications abuse of process timer, too much, being provided with to overfrequency some is inessential to user, or even complete unnecessary task of timer, cause the modules such as CPU and radio frequency in running order too frequently, cause that power consumption seriously increases, the stand-by time of the serious mobile phone shortening.
Summary of the invention
The technical problem to be solved in the present invention is: in assurance system, application program, use timer function completely normal, again subprogram is used to timer too continually, do some redundancies, matter of no consequence carries out some adjustment, reduce their frequency of utilization, so that saving electric weight, reduces power consumption.
The present invention is by the following technical solutions:
The invention provides a kind of timer that passes through to optimize, reduce the method for mobile telephone power consumption, comprising:
One, a kind of recognition methods of redundancy timer is provided, and automatically identifying which timer is strictly according to arranging preset time, can not change the timer of time; Which timer is redundancy, and timer, can fall low-frequency by adjusting (prolongation) timer time too frequently;
Two, provide a kind of redundancy timer time method of adjustment, so that the timer after adjusting can guarantee the normal operation of application program, do not make mistake.
Also comprise:
Three, when cell phone standby, interval time adjusted (prolongation) by the timer to redundancy timer, reduces the number of times that redundancy task of timer is carried out, and reaches the object of saving stand-by power consumption.
What need to specialize is to adjusting the interval time of timer, just must be can carry out when cell phone standby, if user uses, in order to guarantee user's experience, can not adjusting the interval time of timer.
1, the recognition methods of redundancy timer:
We are defined as redundancy timer when cell phone standby, and the timer of some non-essential tasks is made on high frequency ground repeatedly.Such as: when the cell phone standby, high frequency accessing specific website, downloads ad resource, obtain up-to-date notification message, check the timer of the version that whether upgrades etc.
The recognition methods of redundancy timer is divided into manually and automatic two kinds.
Manual identified method, by artificial set up applications, the timer frequency of analysis application when standby, and the necessity of the thing done of timer, carry out the timer of analysis application when standby, whether be the timer of redundancy, have the time interval that there is no need to adjust (prolongation) timer.If analyze the timer that application program has redundancy, application name is recorded, follow-up when cell phone standby, if there is the timer of this application, can adjust the cycle of (prolongation) timer,
Reduce call number regularly.
What application program referred to here is exactly the application software of installing in smart mobile phone, such as the software of android platform installation, such as UC browser, game, QQ chat tool etc.
Automatic recognition method, while being located at cell phone standby, add up each be applied in a period of time T(such as: 1 hour or 24 hours) in, the times N that timer is triggered, set in a trigger rate K(reality, K is approximately set to 15 ~ 20 times/hour), if N/T > K, think that the timer of this application program has redundancy when standby, can the timer interval △ t of application programs when standby, be optimized adjustment.
Optionally, add up the times N that in a period of time, each application program timer is triggered in the above,
Can also synchronously add up this timer in addition and whether have data service (IP operation), if had, add up the number of times M of the usage data business of each application, setting M in the frequency P(reality that data service triggers can be set to 10 ~ 15 times), if M/T > P and N/T > K, judge when standby, this application has the timer of redundancy, can the timer interval △ t of application programs when standby, be optimized adjustment.
Need to specialize:
1) some system-level special application for example,, such as the application (android of android platform, com.android.phone) that keeps mobile phone at net, although timer is also very frequent, can not be the timer of redundancy.
2) requirement of the recognition methods of redundancy timer also can be very loose, in reality test, except some special system-level application, can not adjust timer the cycle, and other all application can be adjusted with timer adjustment method below.The timer cycle preferred version when the recognition methods of redundancy timer is cell phone standby thus, rather than necessary step, the identification of redundancy timer also can be omitted.
2, redundancy timer time method of adjustment:
The time interval of supposing redundancy timer is △ t.If △ t is less than a specific value Tmin(, for example suppose Tmin==2s) or △ t be greater than a specific value Tmax (for example supposing Tmax=30*60s), △ t just need not adjust.
It is mainly that the timer that guarantees the short time can respond in time that very little △ t is got rid of, and avoids postponing.
Very large △ t is got rid of, because the timer frequency of situation is very low like this, there is no need to adjust, mainly still guarantee its temporal accuracy.
If:
Tmin < △ t < Tmax, this △ t can adopt a kind of adjustment the in several method below:
Method one:
It is C that an adjustment parameter is set, (wherein C >=1),
Timer after adjusting is interval time: △ t=△ t * C;
Method two:
Also the time can be divided into the different time periods by size, each time period, to set one and adjust parameters C (n), the timer after adjusting is interval time: △ t=△ t * C (n);
For example the time period is divided into:
Method three:
Counting user is at certain hour section T(for example: one week) in, the different time period (such as every day is according to being divided into 24 intervals for 24 hours), user uses the statistical method of the frequency U(mobile phone frequency of utilization of mobile phone to be at different time intervals, in a period of time (such as: one hour), user opens mobile phone screen and operates and count 1, otherwise count 0, within continuous several days, add up, can obtain using by the user of division in 24 hours the frequency of mobile phone).
When cell phone standby, if the cycle of timer needs to adjust, first according to the current time, determine the residing time period of current time (for example: point) in 9 points ~ mornings 10 in the morning, inquire about this time period user's mobile phone frequency of utilization U(t), according to U(t) height obtain corresponding C (t).
U(t) with the pass of C (t) be: if U(t) height, the parameters C (t) of adjusting is less, if U(t) lower, C (t) is higher: the timer time after adjustment is spaced apart: △ t=△ t * C (t);
For example:
Beneficial effect: adopt the method for the invention, both can guarantee the normal operation of cell phone system and application program, when cell phone standby, can identify again certain applications program redundancy, timer too frequently, by extending the gap periods of relevant timer, reach the call number that reduces relevant timer, reduce power consumption, the object of the service time that extending cell phone once charges.According to test, adopt the present invention, both can guarantee that cell-phone function was in full accord with common cell-phone function, can reduce cell phone standby power consumption 30 ~ 80% again, the service time that extending cell phone charges once greatly, there is extraordinary society and market value.
