Nokia 5 user guide

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.
