Nokia T20 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, select which sounds to keep.
3. Use wired headphones, rather than the loudspeaker.
4. Set the 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.
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 tablet scanning for available wireless networks. Tap Settings > Network & Internet > Wi-Fi, and disable Use Wi-Fi.
