How to calculate power consumption of android app?
android, performance
Solution
Using adb tools you can view power consumption of each running app
adb shell dumpsys cpuinfo
sample output
Load: 1.12 / 1.07 / 1.01
CPU usage from 11344ms to 1613ms ago:
10% 122/system_server: 5.8% user + 4.5% kernel / faults: 989 minor
0% 233/com.htc.android.wallpaper: 0% user + 0% kernel / faults: 910 minor
0.8% 271/com.htc.launcher: 0.8% user + 0% kernel / faults: 832 minor
0% 40/panel_on/0: 0% user + 0% kernel
0% 8/suspend: 0% user + 0% kernel
0% 54/synaptics_wq: 0% user + 0% kernel
0.2% 57/w1_bus_master1: 0% user + 0.2% kernel
0% 253/com.android.phone: 0% user + 0% kernel / faults: 3 minor
0% 13/kondemand/0: 0% user + 0% kernel
0% 56/curcial_wq: 0% user + 0% kernel
0% 2879/com.htc.bg: 0% user + 0% kernel / faults: 8 minor
0% 2904/dhd_dpc: 0% user + 0% kernel
0% 2906/com.google.android.apps.maps:NetworkLocationService: 0% user + 0% kern
Using batterystats you can view each app's battery usage and power consumption:
adb shell dumpsys batterystats
To list all available dumpsys tools:
adb shell dumpsys -l
To configure adb tools: http://developer.android.com/guide/developing/tools/adb.html
Problem
Whether there is any formula ,Api or method for it? I want to test the power consumption of different apps.
