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. 40. 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 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 automatic download of new maps. See "Maps", p. 57.

●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 Tools > Settings >

Phone > 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. Press , and select Tools > Settings > General > Personalisation > Display and Light time- out or Brightness.

●Leaving applications running in the background increases the demand on battery power. To close
