battery power and reduce the battery lifetime. 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. Deactivate Bluetooth technology when you
do not need it.

other features, increase the demand on battery
power. WLAN on your Nokia device deactivates

you can specify that your device does not scan, or
scans less often, for available networks in the
background.
