Prolong battery life
Many features in your device increase the demand
on battery power and reduce the battery life time.
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. To prolong the operating time
of your device, turn the 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 another 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. WLAN
switches off in between background scans.

, the WLAN availability
icon is not shown in the standby mode. However,
you can still manually scan for available WLAN
networks and connect to WLAN networks as
usual.
●
If you have set

in connection settings, and
there is no packet data coverage (GPRS), the
device periodically tries to establish a packet

demand on battery power. To prolong the

●
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 device from
automatically downloading new maps.
