Nokia 3.4 user guide

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 > 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 disabled.
6. Stop apps from running in the background: tap stop, swipe right through all the apps and tap CLEAR ALL.
7. Use location services selectively: switch location services off when you don’t need them. Tap Settings > Location, and disable 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 & Internet > Wi-Fi, and disable Use 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.
