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 establish a packet data connection. To prolong the 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.
