Nokia C31 2nd Edition user guide

To save power:

1. Always charge the battery fully.
2. Mute unnecessary sounds, such as touch sounds. Tap Settings > Sound, then 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 > 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. 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 and internet > Internet, then switch off Wi-Fi. If you're listening to music or otherwise using your phone but don't want to make or receive calls, switch the flight mode on. Tap Settings > Network and internet, then switch on Flight mode. Flight mode closes connections to the mobile network and switches your device’s wireless features off.
