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 coonectivity, or allowing such features to run in
the background while using other features, increase the demand on battery
power. Deactivate Bluetooth connectivity when you do not need it.
•
If you have selected
Packet data connection

When available
in the
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
