Prolong battery life
Many features in your device increase the
demand on battery power and reduce the
battery lifetime. To save battery power,

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

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 3G network.
You can set the device to use only the
GSM network. To use only the GSM
