LeanDroid

LeanDroid is a lightweight battery saver that automatically manages power-hungry wireless connections to significantly lengthen the battery life of your devices.



It can disable WiFi, Cellular Data (2G, 3G, LTE), Bluetooth, and GPS after a certain time with the screen off to conserve battery power and lower data usage. Connections will be re-enabled when the screen is turned back on or unlocked, and periodically to allow for notifications to come in. LD will only re-enable connections that it disabled, not all of the selected connections. There are many additional options to set to your preference.



If you have an issue, please email [email protected], or use the contact menu option from the app before leaving a negative review!



Some options explained:
Disable Wi-Fi/Data except if active - Connections are only disabled if there is negligible data transfer while 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.



Disable Wi-Fi except if browser has web 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 time - Connections will not be disabled between this time of day. Connections will automatically be turned on if this time is reached and the connections have already been disabled.



Re-enable periodically while screen off - Briefly re-enable the connections in the background, at the specified interval, to allow for sync, and notifications to come in.



Re-enable WiFi first - Re-enable and attempt to connect Wi-Fi before enabling network data (maximum wait of 8s).



Note:
-Having data enabled while WiFi is connected does NOT use additional battery power.
-Dual SIM phones may not disable data on both SIMs as the required code varies by manufacturer.
-Bluetooth functionality is only available on ICS+.
-GPS, Cell radio functionality is only available on KitKat+ and requires ROOT.
-Cellular data requires ROOT on Lollipop only!
-If you are on Android 4.4.1 - 4.4.2, a persistent notification is required due to a bug in KitKat where services cannot restart themselves once killed by the system. If you would like to hide the notification, find LeanDroid in Settings -> Apps, and un-check "show notifications". Do not swipe LeanDroid away from Recent Apps, as this will also cause this bug.
