LeanDroid is a power-saving app that has the capability to disable Wi-Fi, cellular data, cellular radios, Bluetooth, and location (networks and GPS). It can also switch cellular network types.

It will do this after the screen turns off to conserve battery power. LeanDroid also has the ability to decrease data usage when you aren’t using your phone.

The application is compatible with both Wi-Fi and Wi-Fi hotspots. It is also compatible with various Android devices.

The connections are automatically restored when the screen is turned back on, or unlocked. You may, in addition, choose to restore connections periodically while the screen is off.
