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. To further reduce battery consumption,
you can specify that your device does not scan, or
scans less often, for available networks in the

icon is not shown in the standby mode. However,
you can still manually scan for available WLAN
