Auto power off your device to save battery life.
**** ROOT Device Only ****
* Auto power off your Android device to save battery life
* You could set a time out after screen off or set a time out after charger unplugged
p.s. This app is not suitable for phone device, because you always want your phone could standby for a call.
Possible scenario:
* Your table is not be used very often, and you want to charge it every time. So you could enable auto power off function after screen off.
* Your Android device is set on vehicle, and power cord is always connected. So you could enable auto power off function after charger unplugged (vehicle shut down).
