Battery Life
The Lithium-Ion (Li-Ion) battery life is dependent upon the
application and operating environment. For example, estimated
battery life will be approximately 34 hours with the unit turned on
but idle, with the backlight on, all radios and compass off when
using a new battery.
Tips for extending the battery life:
- Display backlight: Tap / Settings / System / Backlight to
minimize the amount of time the backlight stays on and dim it
to only as bright as required to view the display.
- Wi-Fi, Bluetooth, camera, or barcode scanner: If your unit
comes with any of these options installed, use ONLY when
necessary. Turn off when not needed.
- Flashlight: Minimize the use of the flashlight.
- WWAN: Turn the phone off when not in use.
- Cold temperatures: Keep the unit as close to room ambient
temperature (77 °F or 25 °C) 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 in use.
- Auto features: Tap / Settings / Power / Advanced. Specify
your unit to turn off in a short time if not in use. Tap /
Settings / Bluetooth / Wake Settings. Turn off Allow
Bluetooth activity to turn the device on. Bluetooth could turn
on your unit, transfer data and drain the battery.
- Heavy processing by the CPU may have some impact on battery
life, but is typically less significant.
Charging the battery
The battery can be charged in the unit or apart from the unit with an
external battery charger (sold separately, as an accessory). Connect
the AC plug for your country 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 charged in about 3 hours.
A full charge is indicated by the battery indicator (left LED) turning
green. The recommended temperature range for charging is
between +32 °F and +104 °F (0 °C and +40 °C). If the battery
temperature is outside of this range, the battery may not charge.
Warning! Be sure to only use the AC adapter included with your
unit. Use of other adapters may void the product warranty.
