In order to realize object of the present invention, a kind of detection method of a kind of application program power consumption based on system shown in Fig. 1 is additionally provided in present embodiment, Fig. 3 shows the process flow diagram of a kind of application program power consumption detection method in this embodiment, and the method mainly comprises the following steps:
Step S21: record move equipment often consumes the time interval that single-candidate presets electricity;
The situation of change of monitoring mobile device battery electric quantity, the also record move equipment that obtains often consumes single-candidate and presets the quantitative moment, battery capacity value is divided into multiple time interval, the power consumption of the mobile device after dividing corresponding to each time interval is identical, and power consumption is that single-candidate presets electricity.
Each time interval has an initial time and end time, i.e. moment of terminating of moment (start time in current time interval) of terminating of previous time interval and current time interval.
Consider the flash-over characteristic of battery, battery discharge is not Uniform Discharge, and the speed of that is application program power consumption in the process run not is equal, and the time therefore consuming single-candidate electricity used is probably different.The situation of change of monitoring battery electric quantity, single-candidate is preset electricity and can be represented with the number percent taking mobile device battery total capacity, such as a%, wherein, 0<a≤50, if the value of a is 1, electricity record time interval of every consuming cells total volume 1%; Single-candidate is preset and quantitatively also can be represented with the single-candidate charge value consumed, and such as single-candidate charge value is q
1, 0<q
1≤ battery total capacity, if q
1when value is 20mAh, often consume electricity record time interval of 20mAh.
Such as, the battery capacity of the mobile phone of an Android system is 2000mAh, beginning timing is established by cable from being full of, 40 minutes post consumptions 1% of battery capacity, namely consume the electricity of 20mAh, dump energy is 99% of battery capacity, 1% is consumed again after 30 minutes, 1% is consumed again after 20 minutes, 1%...... is consumed again after 30 minutes, as shown in Figure 5, first time interval is the time period (electricity is depleted to the interval at 99% place by 100%) of 0-40 minute, the time period (electricity is depleted to the interval at 98% place by 99%) that second single-candidate interval is 40-70 minute.Represent that the single-candidate of consumption presets electricity by the form of number percent (a%) in the present embodiment.
After battery capacity value being divided into the multiple time intervals often consuming and preset quota electricity, multiple time interval forms the coordinate axis of a time interval, as shown in Figure 5.
Step S22: the Startup time of monitoring mobile device foreground application and close moment;
Monitor the Startup time t of each foreground application
1with close moment t
4monitoring concrete grammar is: (as 1-30S) once monitors at set intervals, can system API(application programming interfaces be passed through) obtain current Activity storehouse, and obtain the application of storehouse stack top, the application being positioned at storehouse stack top is foreground application.Contrast with the foreground application to obtain before after obtaining, if the application that obtains of current monitoring moment is with previous to monitor the application that the moment obtains different, then currently monitor the end time that the moment is previous foreground application, be the start time applied below simultaneously.As shown in Figure 6, application A brings into operation from during 0s, and become B to foreground application when the 3rd second, then think that A has run 3S, when the 4th second, foreground application becomes C, then B has run 1S.As shown in Figure 5, foreground application D at front stage operation, terminates front stage operation to 110min from when 20min, that is the initial time t of foreground application D
1for this moment of 20min, finish time is this moment of 110min, and this foreground application is the 90min at front stage operation altogether.
Step S23: the power consumption Q calculating foreground application.
The Startup time t of electricity and foreground application is preset according to the single-candidate described in step S21
1with close moment t
4the position of the coordinate axis of the time interval formation at place, determines the power consumption of described foreground application.
Wherein, electricity, Startup time t is preset according to single-candidate
1with close moment t
4the position of the coordinate axis that the described time interval be positioned at is formed, determine the power consumption Q of described foreground application, comprising:
I. the Startup time t of foreground application is obtained
1with close moment t
4the number n of the complete time interval crossed over;
Ii. preset quantitatively and the value of the number n of the complete time interval crossed over according to described single-candidate, calculate the power consumption Q of foreground application, the formula calculating the power consumption Q of described foreground application is:
The power consumption Q=(n+1 of foreground application) × q, wherein, q is that single-candidate presets electricity.
As the Startup time t of foreground application
1with close moment t
4be in interval at the same time, i.e. the Startup time t of foreground application
1with close moment t
4when the number of the complete time interval crossed over is zero, the formula that power consumption determination module calculates the power consumption Q of foreground application is:
Power consumption Q=(the t of foreground application
4-t
1)/(t
3-t
2)] × q,
Wherein, t
2represent the initial time of the time interval at foreground application Startup time place, t
3represent the end time of the time interval at foreground application Startup time place, q is that single-candidate presets electricity.
Carve t upon start up
1with close moment t
4when being in different time intervals, the formula that power consumption determination module calculates the power consumption Q of foreground application is:
Power consumption the Q=[(t of foreground application
3-t
1)/(t
3-t
2)+n+ (t
4-t
5)/(t
6-t
5)] × q;
Wherein, t
2represent the initial time of the time interval at foreground application Startup time place, t
3represent the end time of the time interval at foreground application Startup time place, t
5represent the initial time of the time interval at foreground application close moment place, t
6represent the end time of time interval at foreground application close moment place, the number of the complete time interval that the coordinate axis that n is formed at time interval for foreground application is crossed over, q is that single-candidate presets electricity.
For the foreground application D in Fig. 5, foreground application D within the 90min time period of front stage operation, span the time interval that two (second and the 3rd) is complete, this application D started (t in the 20th minute
1=20), the 110th minute time terminate front stage operation (t
4=110), suppose that the total volume of battery is 2000mAh, single-candidate preset that electricity is battery total capacity 1%, the electricity that so this application D consumes in front stage operation process is:
The power consumption Q of foreground application D
d=[(t
3-t
1)/(t
3-t
2)+n+ (t
4-t
5)/(t
6-t
5)] × q=[(40-20)/(40-0)+2+ (110-90)/(120-90)] × 1% × 2000=63.4mAh.
Due to foreground application start time, the electricity of its Startup time mobile device may be full of electricity, also may not be full of electricity, if be full of the state of electricity and electricity is 100%, can determine that foreground application starts the single-candidate at place easily according to the time interval divided in step S21 interval; If when foreground application starts, the electricity of equipment is discontented state, the electricity of mobile device when also needing to monitor and record the startup of this foreground application, determines the time interval at foreground application Startup time place according to this electricity.Determine according to the electricity of mobile device Startup time in present embodiment that the mode in the single-candidate interval at Startup time place is: the single-candidate that first time interval entered when Startup time electricity consumes again is designated as foreground application Startup time place is interval.
Such as, when a certain foreground application starts in the present embodiment, the electricity monitoring equipment is 98%, when determining that the single-candidate at foreground application Startup time place is interval, due to when foreground application starts 98% electricity uncertain be just fallen 98% by 99%, or be about to fall 97% by 98%, when adopting above-mentioned side to determine formula, according to the time interval that step S21 divides, for the situation of Startup time electricity 98%, when the electricity of 98% consumes again, its first time interval entered is the time interval at 97%-96% place, so, the time interval at the Startup time place of this foreground application is a single-candidate interval, the 3rd shown in Fig. 5.After the time interval determining Startup time place, power consumption can be confirmed according to divided time interval and aforesaid way.
Certainly, after the power consumption calculating a foreground application, also can estimate the electricity of foreground application at unit interval internal consumption, total electricity of a period of time internal consumption is the electricity of unit interval internal consumption, i.e. foreground application unit interval power consumption Q'=Q/(t divided by the time run
4-t
1).
Because the power consumption of background application is little compared with the power consumption of foreground application, the power consumption of background application therefore can not be considered when the application of running background is few.When above-mentioned steps S21 ~ step S23 is and does not consider background application power consumption, detect the method for each foreground application power consumption.But when the application of running background is more, the proportion that the electricity consumed accounts for total power consumption is still larger, therefore in order to improve the precision of the power consumption detecting each foreground application, a setting threshold value (as 3-5) can be set, when the number of the application of running background is greater than setting threshold value time, consider the power consumption of the application of running background, the power consumption of background application can not be considered when the number of the application of running background is less than or equal to threshold value time.
When considering the power consumption of background application, a kind of application program power consumption detection method described in present embodiment also comprises the step calculating the accurate power consumption of foreground application according to the power consumption of described foreground application, and this accurate power consumption refers to that the number when the background application of mobile device is greater than the power consumption of foreground application when setting threshold value.
The method of monitoring running background time (Startup time and the closedown of background application) can be identical with the method for monitoring front stage operation time, namely can obtain current Activity storehouse by system API at set intervals, the application except being positioned at storehouse stack top is background application.Due in time being applied in running background, its power consumption is very low, so cannot directly test.Give in present embodiment and a kind ofly mode by experiment can measure the mode that background application power consumption accounts for total power consumption number percent, its process flow diagram as shown in Figure 4:
A. first, all background application of mobile device are closed, the power consumption Q of record foreground application in setting-up time
before;
B. keep the mobile device running status identical with during all background application of described closedown, open the background application of setting quantitative range, record foreground application and the background application total power consumption Q at setting-up time
always.Wherein, identical mobile device running status refers to identical with the running status of equipment in step a, and the charge condition foreground application that is identical, that run comprising battery is mutually equal.Background application in setting quantitative range refers to and divides certain interval to the number of background application, and as shown in table 1,1-5 background application is an interval range, and 6-10 is an interval range.
C. the power consumption calculating the background application of setting quantitative range accounts for the number percent of total power consumption, and computing formula is (Q
always-q
before)/Q
always;
D. judge to calculate the number of times that the power consumption of background application accounts for the number percent of total power consumption and whether reach setting value, if then enter next step, then return step a if not, repeat step a ~ c;
E. the power consumption of the background application repeatedly calculated is accounted for the mean value of the number percent of total power consumption, account for the end value p of total power consumption number percent as background application;
F. the accurate power consumption Q of foreground application is calculated according to the power consumption Q of foreground application and described end value p
essence, computing formula is: Q
