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. 34. 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
