On your device running Android 5.0 or higher, you can use battery saver to help improve battery life. You can also set your device to turn on battery saver automatically based on how much battery your device has remaining. Turning battery saver on limits vibration, location services, and most background data.
Follow these steps:
- Open Settings.
- Under "Device," touch Battery.
- Touch the menu icon, then touch Battery saver.
- Move the switch to On. The notification and navigation bars at the top and bottom of your screen will turn orange when battery saver is turned on.
To set your device to turn on battery saver automatically based on your remaining battery life, touch Turn on automatically and select "at 5% battery" or "at 15% battery."
