You do not need to charge your battery so often if you do the
following:
•
Close applications and data connections, such as your
WLAN or Bluetooth connection, when not in use.
•
Decrease the brightness of the screen.
•
Set your device to enter power saver mode after the
minimum period of inactivity.
•
Deactivate unnecessary sounds, such as touch screen and
key tones.
