Wireless Lockdown Timer (Free)

Cut off wireless communication of your device at a chosen time and save battery.

# Doesn't work for Android 4.2.2 devices, since apps are not allowed to turn on/off the airplane mode anymore from that version. #

This app makes your device shut down all its network and radio communications at a selected time (and even turns it on again if desired). Effectively your device will be put into airplane mode (but you can choose to turn off Wi-Fi only). This app even remembers the scheduled lockdown time after rebooting your device.

This app is very useful if you don't want to drain your battery over night keeping wireless communication turned on all the time.

Note: If your SIM card is protected by a PIN code you will have to enter it when turning the airplane mode off again. The app can't do this for you.
