LeanDroid can automatically disable Wi-Fi, cellular Data*, cellular radio*, Bluetooth, and location* (networks and GPS), and switch cellular network modes. It will do so a certain amount of time after the screen turns off to conserve battery power and lower data usage. Connections are automatically restored when the screen is turned back on, and periodically while the screen is off to allow for push notifications. Only connections that were automatically disabled by LD are re-enabled. Connections that were manually disabled are left untouched. There are many additional options and exceptions to set to your preference.

Some options explained:
Disable Wi-Fi/Data/Network mode except if active - Connections are only disabled if there is negligible data transfer while the screen is off. Some music services don't "stream" but instead download entire songs at once, and they might do this while the screen is still on. Please set the disable time interval to at least the length of your average song so LD can catch data activity while the screen is off or use the except if "Except if apps running" option.

Disable Wi-Fi except if requires browser login - WiFi is not disabled if it requires a browser login (common for public hotspots or guest networks), so that you do not have to re-enter the password when it is re-enabled.

Disable except if apps running - No connections are disabled if one of the selected apps is found to be running in the foreground or has foreground services. There is a sub-option to also detect background services of the apps.

Restore Data after waiting xx seconds for Wi-Fi to connect - Wait for WiFi to connect before re-enabling cellular data. This prevents data from re-connecting for just a couple of seconds.
