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. Turn
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 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 Packet data connection to When
available in connection settings, and there is no packet
data coverage (GPRS), the device periodically tries to
operating time of your device, select Packet data
connection > When needed.
● The Maps application downloads new map information
when you move 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 UMTS network. You
can set the device to use only the GSM network. To only
use the GSM network, select Menu > Settings and
Connectivity > Network > Network mode > GSM.
