Detailed overview
Automatically disable connections
LeanDroid can automatically disable Wi-Fi, cellular data*, cellular radios*, Bluetooth, and location* (networks and GPS). It can also switch cellular network types* (ex. 4G to 2G). It will do this after the screen turns off to conserve battery power and lower data usage when you aren't using your phone.

Disable interval
Sets the amount of time to wait after the screen turns off before disabling connections (premium).

Restore connections
Connections are automatically restored when the screen is turned back on, or unlocked. You may also choose to restore connections periodically while the screen is off to allow for push notifications and background sync. Only connections that were automatically disabled by LeanDroid are re-enabled. Connections that were manually disabled are left untouched.

Sync interval
Sets how often to restore connections while the screen is off (premium).

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

Disable exceptions
Various options that prevent connections from being disabled. Options under the "All toggles" section will prevent all connections from being disabled. Options under "Specific toggles" will only prevent the respective connections from being disabled. If an exception is found, LD will check again after another disable time interval has passed.

Disable except if using these apps
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 apps.

Disable Wi-Fi/Data/Network type except if active
Data connections are not disabled if there is data transfer when it comes time to disable them. If the data transfer rate surpasses the chosen value, data connections will be kept enabled so that data-sensitive tasks are not interrupted. Most music apps don't continuously stream but instead download entire songs at once, and they might do this before LD checks data transfer. In these scenarios, you may also want to check the "except if using these apps" 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.
