Prolong battery life
Many features in your device increase the demand on
battery power and reduce the battery lifetime. 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.
Deactivate Bluetooth technology 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 deactivates 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.

much in your area, your device must scan for the
available network repeatedly. This increases the
demand on battery power.
