Prolong battery life
Many features in your device increase the demand
on battery power and reduce the battery life time.
To save battery power, observe 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. Switch off Bluetooth 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. The 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 not scan, or scans less
often, for available networks in the background.

information when you scroll to new areas on the

power. You can prevent the automatic download

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 use only the GSM network,
select Menu > Settings and Connectivity >
Network > Network mode > GSM.
● The backlight of the display increases the
demand on battery power. In the display
settings, you can change the length of the time-
out period after which the backlight is switched
off, and adjust the light sensor that observes
