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. To prolong the operating time of your
device, turn the 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 another 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. WLAN switches off in between
background scans. See "Wireless LAN", p. 32. 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 When
available in connection settings, and there is no
packet data coverage (GPRS), the device periodically
tries to establish a packet data connection, which
causes increased demand on battery power. To
prolong the operating time of your device, select
Packet data connection
>
When needed .
● The Maps application downloads new map
information when you scroll to new areas on the
map, which increases the demand on battery power.
You can prevent the device from automatically
downloading new maps. See "Maps", p. 84.
● 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. If it is not available, the device uses the
available GSM network. To only use the GSM
network, press , and select Tools

on battery power. To change the time-out after
which the backlight is switched off, press , and
select Tools
