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.
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.
See "Wireless
LAN", p. 97.
When
Scan for networks
is set to
Never
, 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
Packet data connection
to

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

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
only use the GSM network, press

The backlight of the display increases the demand on
