Nokia 4.2 User Guide

To save power:

• Always charge the battery fully.
• Mute unnecessary sounds, such as touch sounds. Tap Settings > Sound > Advanced, and under Other sounds and vibrations, select which sounds to keep.
• Use wired headphones, rather than the phone's speaker.
• Set the phone screen to switch off after a short time. Tap Settings > Display > Advanced > Sleep and select the time.
• Tap Settings > Display > Brightness level. To adjust the brightness, drag the brightness level slider. Make sure that Adaptive brightness is disabled.
• Stop apps from running in the background: swipe up the home key and swipe up the app you want to close.
• 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.
• Switch on the power saver: tap Settings > Battery > Battery saver and switch to On.
• Use location services selectively: switch location services off when you don’t need them. Tap Settings > Security & location > Location, and disable Use location.
• 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 airplane mode on. Tap Settings > Network & internet > Advanced > Airplane mode. Flight mode closes connections to the mobile network and switches your device's wireless features off.
