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.
