● 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.

● 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 Packet

data connection > When needed.

● 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. You can set the device to use only the GSM network. To only

use 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 time-out after which the backlight is switched off, and

adjust the light sensor that observes lighting conditions and adjusts the display

brightness. Select Menu > Settings and Phone > Display > Light time-out or

Light sensor.

● Leaving applications running in the background increases the demand on battery

power. To close the applications you do not use, press and hold the menu key, select

Options > Show open apps., and navigate to the application with the menu key.

Press and hold the menu key, and select Exit.
