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 connectivity, or allowing such
features to run in the background while using other
features, increase the demand on battery power.
Deactivate Bluetooth connectivity when you do not need
it.
● Features that use a wireless LAN (WLAN), or allowing such
features to run in the background while using other
features, increase the demand on battery power. The
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 selected Packet data connection
available in the 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

● 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. To set
the device to use only the GSM network, select

● The backlight of the display increases the demand on
battery power. In the display settings, you can change the
time-out period after which the backlight is switched off,
and adjust the light sensor that observes lighting
conditions and adjusts the display brightness. Select
