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 connectivity 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.
•
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 needed
.
•
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
download of new maps.
•
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.
