Mobile devices components with the highest energy requirements are screen and cellular module. With this application you can set automatic brightness decreasing after selected hour. Although the brightness is reduced in poorly lit conditions the screen should remain clear.
Devices with Android 4.1.x and below are able to use scheduled powering off the cellular module. Bear in mind that at this time you won't be able to do calls and messages will be received after powering the module back.
