App performance test: (IV) power

app Performance testing ：（ Four ） Electric quantity

The following is an analysis of the electric quantity ：
Attention should be paid to , Cell phone through USB Connecting to a computer , The phone will be in a state of charge , It must be ensured that the mobile phone is in a non charged state

• Switch the non charging state
  command ：adb shell dumpsys battery set status 1
  among status 1 Non charged ,status 2 Is in charge state
  namely

• Switch to charging state
  command ：adb shell dumpsys battery set status 2

• Get electricity
  command ：adb shell dumpsys battery
