    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. Always charge the battery fully.
    2. Mute unnecessary sounds, such as touch sounds. Tap Settings > Sound > Advanced, and under Other sounds and vibrations, select which sounds to keep.
    3. Use wired headphones, rather than the loudspeaker.
    4. Set the phone screen to switch off after a short time. Tap Settings > Display > Advanced > Sleep 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 disabled.
    6. Stop apps from running in the background: swipe up the home key and swipe up the app you want to close.
    7. Enable Adaptive Battery. Limit battery for apps that you don't use often. The notifications may be delayed for these apps. Tap Settings > Battery > Adaptive Battery.
    8. Switch on the power saver: tap Settings > Battery > Battery saver, and switch to On.
    9. Use location services selectively: switch location services off when you don’t need them. Tap Settings > Security & Location > Location, and disable Use location.
    10. Use network connections selectively: switch Bluetooth on only when needed. Use a Wi-Fi connection to connect to the internet, rather than a mobile data connection. Stop your phone scanning for available wireless networks. Tap Settings > Network & Internet > Wi-Fi, and disable Wi-Fi. If you're listening to music or otherwise using your phone, but don't want to make or receive calls, switch the airplane mode on. Tap Settings > Network & Internet > Advanced > Airplane mode.

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