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