Android省电策略及测试

1、电源测试
----------------------------------------------------

adb shell dumpsys battery

  mSavedBatteryAsoc: 95
  mSavedBatteryMaxTemp: 473
  mSavedBatteryMaxCurrent: 3000
  mSavedBatteryUsage: 19972
  FEATURE_SAVE_BATTERY_CYCLE: true

2）模拟未充电模式：
adb shell dumpsys battery unplug
通过命令1看是否生效
重置电源充电状态：adb shell dumpsys battery reset

3）省电模式：
adb shell settings put global low_power 1

4）API：
PowerManager.isPowerSaveMode()
PowerManager.ACTION_POWER_SAVE_MODE_CHANGED

2、后台限制
