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.

The Maps application downloads new map
information when you scroll to new areas on the
map, which increases the demand on battery power.
You can prevent the automatic download of new

If the signal strength of the cellular network varies
much in your area, your device must scan for the
available network repeatedly. This increases the
demand on battery power.
If the network mode is set to dual mode in the
network settings, the device searches for the 3G
