Q: How do I save battery power?
A: Many features in your device increase the demand on
battery power and reduce the battery life time. To save
battery power, do the following:
• Deactivate Bluetooth connectivity when you do not
need it.
• Stop the background scans for WLAN. Select Menu >
Ctrl. panel > Settings and Connection > Wireless
LAN > Show WLAN availability > Never. You can still
manually scan for available WLANs and connect to
WLANs as usual.
• Set the device to use a packet data connection only if
you start an application or action that needs it. Select
Menu > Ctrl. panel > Settings and Connection >
Packet data > Packet data connection > When
needed.
• Prevent the device from automatically downloading
new maps in the Maps application. Select Menu >
Applications > Maps and Options > Settings >
Internet > Connection.
• Change the time-out after which the backlight is
switched off. Select Menu > Ctrl. panel > Settings
and General > Personalisation > Display > Light
time-out.
• Close the applications you are not using. Press and hold
the home key. Scroll to the application, and press the
backspace key to close the application.
