To use Servicely, your Android device needs to be 'rooted.' Once that's out of the way, the app is really easily to use. All you have to do is select the apps or processes you want to deactivate when your screen's off. That's right, you can deactivate any process that's sucking your battery dry.
Servicely is a really interesting app that's especially useful if you use it along with other apps like Wakelock Detector. This way you can quickly detect what app or process is draining your battery and put it to sleep.
Requires Android 5.0 or higher
