Prolong battery life

Many features in your device increase the demand on battery power and reduce the battery life time. To save battery power, note the following:

●Features that use Bluetooth technology, or allowing such features to run in the background while using other features, increase the demand on battery power. Turn Bluetooth technology off when you do not need it.

●Features that use wireless LAN (WLAN), or allowing such features to run in the background while using other features, increase the demand on battery power. WLAN on your Nokia device

switches off when you are not trying to connect, not connected to an access point, or not scanning for available networks.

However, you can still manually scan for available WLAN networks and connect to WLAN networks as usual.

If the network mode is set to dual mode in the network settings, the device searches for the
