Working with the Unit and the Battery

Battery life: The Lithium-Ion (Li-Ion) battery life is dependent
upon the application and operating environment. Frequent keypad
and display backlight usage, heavy usage of the Wireless LAN
(WLAN), cold temperatures, GPS, and high power consumption
CF and SD devices can all significantly reduce the battery life.
Other factors that may have some impact on battery life include
heavy usage of the Bluetooth radio and heavy processing by the
CPU, but these factors are typically less significant.
Tips for extending the battery life:
- Keypad backlight: The default is off. This backlight uses a lot
of power so use only when necessary. For information on
changing the backlight settings, see page 16.
- Display backlight: The default is on. Minimize the amount of
time the backlight stays on when idle. Dim the backlight to
only as bright as required to view the display.
- Wireless LAN: If your unit comes with embedded WLAN, use
ONLY when necessary. Turn off when not needed.
- Cold temperatures: Keep the unit as warm as possible. If
feasible, keep it inside your coat or a vehicle when not in use.
- GPS: Ensure that the GPS-aware applications that
communicate with the GPS are closed when not being
actively used. The Today screen tells if the GPS is running.
- Expansion ports: Use low-power consumption CF and SD
cards and use them only when necessary.
- Auto features: Tap Start / Settings / System / Power /
Advanced. Make sure the unit is powered off when not in use
with the shortest amount of time.
Charging the battery: The battery can be charged in the unit or
separate from the unit with an external battery charger, sold as an
accessory. Connect the appropriate AC plug to the AC adapter.
Plug into an electrical outlet and plug the barrel end of the AC
adapter into the unit. The unit will be fully charged in about 4 to
4.5 hours. A full charge is indicated by the battery LED (right side
of the unit) turning green. The manufacturer recommended
