70th, processor 72, power consumption monitoring system 74 and galvanometer 76.In the present embodiment, the mobile terminal 7 is mobile phone.
In the present embodiment, the power consumption monitoring system 74 includes：
Acquisition module 700, the current flow of the mobile terminal 7 is obtained for being spaced △ t at predetermined time intervals.
Specifically, the current flow is obtained by the galvanometer 76 measurement.Wherein, the galvanometer 76 is built-in PMIC
High precision electro flowmeter.
Computing module 702, for acquired current flow to be added up according to default testing time section T.
Specifically, in section T of default testing time, △ t are spaced at predetermined time intervals can obtain a current flow,
Obtain multiple current flow I1, I2..., In.Acquired multiple current flows are added up, total current I is obtainedsum=
I1+I2+…+In。
The computing module 702 is additionally operable to calculate the power consumption P and average current of the mobile terminal according to preset formula
Iavg。
Specifically, the preset formula is：
Power consumption P=Isum* △ t*1.0/ (1000*3600),
Average current Iavg=P/T.
Wherein, for the power consumption P, industry generally uses mAH as unit.
Further, the power consumption monitoring system 74 also includes setup module 704, for setting the testing time section T
With time interval △ t.
Specifically, before the power consumption of the mobile terminal 7 is monitored, it is necessary to pre-set testing time section T, that is, monitor
It is the power consumption that the mobile terminal 7 is consumed in testing time section T.Also need to the △ t that set interval, such as two seconds
Clock.
The setup module 706 is additionally operable to set the interface for the current flow for obtaining the mobile terminal 7.
Specifically, defining interface getCurrentNow () obtains the current flow, especially by readTextFile
(new File ("/sys/class/power_supply/battery/current_now "), 0, null) it is to obtain.
Should/data of sys/class/power_supply/battery/current_now catalogue files storage be it is described it is mobile eventually
The present current value at end 7.Obtained after the current flow, preserved into the catalogue file by the galvanometer 76 measurement.
Further, the power consumption monitoring system 74 also includes logging modle 706 and analysis module 708.
The logging modle 706 is used to encapsulate each current flow and corresponding testing time to an array
In, and timing is transferred to file destination.
Specifically, data type CurrentNow is defined, two changes of the current flow and corresponding testing time are included
Amount.A List array is initialized, a present current value is often obtained, while recording the corresponding testing time, and encapsulates
Into a CurrentNow data, it is added in the List arrays.Also, will every several described CurrentNow data
In mono- file destination of all data Cun Chudao in the List arrays, while emptying the List arrays.
The data that the analysis module 708 is used in the file destination draw the electric current fortune of the mobile terminal 7
Row curve.
Specifically, each current flow and corresponding testing time data can be read from the file destination,
Then the electric current operation curve of the mobile terminal 7 is drawn according to the data read by data analysis tool.
The analysis module 708 is additionally operable to according to the electric current operation curve with reference to the operation point to the mobile terminal 7
Analyse the power consumption condition of the mobile terminal 7.
Specifically, after the electric current operation curve of the mobile terminal 7 is drawn out, it can be seen that the mobile terminal 7 exists
Which moment current value is higher, and which moment current value is relatively low.Then, the mobile terminal 7 is being entered according to these moment
Capable operation, you can analyze the specific power consumption condition of the mobile terminal 7.For example, the mobile terminal 7 is being started shooting and dialed
Current value is higher when phone etc. is operated, and power consumption is big, and current value is relatively low when standby, and power consumption is small.
It should be noted that herein, term " comprising ", "comprising" or its any other variant are intended to non-row
