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. 69.

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. To prolong the operating time

of your device, select

.

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 automatic download

of new maps.

See "Maps", p. 54.

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 , and select

The backlight of the display increases the

demand on battery power. In the display

settings, you can change the time-out after

which the backlight is switched off, and adjust

the light sensor that observes lighting conditions

and adjusts the display brightness. Press , and
