Battery life

Get the most out of your phone while getting the battery life you need. There are steps you can take to save power on your phone.

Extend battery life

To save power:

  1. Charge wisely: Always charge the battery fully.
  2. Select only the sounds that you need: Mute unnecessary sounds, such as key press sounds. Tap Settings > Sound, and under Other sounds, select which sounds to keep.
  3. Use wired headphones, rather than the loudspeaker.
  4. Change the phone screen settings: Set the phone screen to switch off after a short time. Tap Settings > Display > Sleep and select the time.
  5. Lower the screen brightness: Tap Settings > Display > Brightness level. Make sure that Adaptive brightness is unabled. To adjust the brightness, drag the Brightness level slider.
  6. Stop apps from running in the background: Press check_box_outline_blank, and close the apps you don’t need.
  7. Enable Battery saver. Tap Settings > Battery > Battery saver, and switch to On.
  8. Use location services selectively: Switch location services off when you don’t need them. Tap Settings > Location, and switch to Off.
  9. Use network connections selectively: Switch Bluetooth on only when needed. Use a Wi-Fi connection to connect to the internet, rather than a cellular data connection. Stop your phone scanning for available wireless networks. Tap Settings > Wi-Fi, and switch to Off. If you're listening to music or otherwise using your phone, but don't want to make or receive calls, switch Airplane mode on. Tap Settings > More > Airplane mode.

Airplane mode closes connections to the cellular network and switches your device’s wireless features off.
