Prolong battery life

Many features in your device increase the demand on
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.
• 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 deactivates
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
background.
• If you have set

network. You can set the device to use only the GSM
network. To use only the GSM network, select
