Battery life

There are steps you can take to save power on your tablet.

Extend battery life

To save power:

  1. Always charge the battery fully.
  2. Mute unnecessary sounds, such as touch sounds. Tap Settings > Sound, and select which sounds to keep.
  3. Use wired headphones, rather than the loudspeaker.
  4. Set the screen to switch off after a short time. Tap Settings > Display > Screen timeout and select the time.
  5. Tap Settings > Display > Brightness level. To adjust the brightness, drag the brightness level slider. Make sure that Adaptive brightness is switched off.
  6. Stop apps from running in the background.
  7. Use location services selectively: switch location services off when you don’t need them. Tap Settings > Location, and switch off Use location.
  8. Use network connections selectively: Switch Bluetooth on only when needed. Stop your tablet scanning for available wireless networks. Tap Settings > Network & internet > Internet, and switch off Wi-Fi.
