Prolong battery life
Many features in your device increase the demand on battery power and reduce
the battery life time. 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 a Wi-Fi network, or allowing such features to run in the
background while using other features, increase the demand on battery power.
The Wi-Fi on your Nokia device deactivates when you are not connected or trying
to connect to an access point, or not scanning for available networks. To further
reduce battery consumption, you can specify that your Nokia device not scan,
or scans less often, for available networks in the background.
● If you have set Packet data connection to When available in 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 Menu
>
Ctrl. panel
>
Settings and Connection
>
Packet
data > 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.
● The backlight of the display increases the demand on battery power. In the
display settings, you can change the length of the time-out period after which
the backlight is switched off. Select Menu > Ctrl. panel > Settings and
General
>
Personalization
>
Display
>
Light time-out .
● Leaving applications running in the background increases the demand on
battery power. To close the applications you are not using, press and hold the
menu key, scroll to the application, and press the backspace key.
● To save power, activate power save mode. Press the power key, and select
Activate power saving . To deactivate power save mode, press the power key,
and select Deactivate power saving . You may not be able to edit the settings
of certain applications when power save mode is activated.
