Why does my Samsung phone keep running out of battery?
Google services aren't the only culprits; third-party apps can also get stuck and drain the battery. If your phone keeps killing the battery too fast even after a reboot, check the battery information in Settings. If an app is using the battery too much, Android settings will show it clearly as the offender.
