LeanDroid’s latest updates add multi-SIM and Android Pie support ~ XDA

We have featured LeanDroid in the past, way back in 2014, where we recognized it as a means to quickly disable data connections to improve battery life. With newer versions of Android, Google itself has implemented some of the same principles in the form of Doze and App Standby, so the average consumer no longer needs to actively do anything on their end. But, if you’re looking to exercise greater control over the radios on your phone the old-fashioned way, you’d be glad to know that LeanDroid continues to be in active development, and now comes with multi-SIM and Android Pie support.

LeanDroid lets you automatically disable your WiFi, cellular, Bluetooth, and GPS connections, and periodically restore them for sync too. You can also setup exceptions with parameters such as time, foreground app, data transfer speed, and more, thus giving you more options than a simple on-off switch. Do note that you are playing around with settings that are necessary for crucial phone activities, so only mess around if you know what you are doing as this app does (intentionally) break the intended behavior of several other apps.
