Power and Battery

How long should it take to charge my battery? more
Your battery can take up to 3 hours to fully charge using the AC charger. It will take much longer using the USB as that is the trickle charge function.
Why won't my device power on? more
Your battery may be drained or is not seated correctly. Try removing and reinserting the battery. If no success, try charging the device using the AC Charger. You will see a white led that pulses around the navigation key while charging. Once charged, it changes to a solid white ring.
How can I optimize my battery's performance? more
There are a few settings that you can change on your device that will preserve battery life.
  • Turn off Bluetooth if you are not actively using it
    • Disable Bluetooth: Tap the Start > Programs > Comm Manager icon on the Today screen and Tap Bluetooth
  • Adjust the settings for your Backlight. Lowering the brightness and timeout will decrease battery consumption.
    • Steps: Go to Start > Settings > System Tab > Backlight
  • Turn off any unnecessary audible notifications (email, SMS, etc.)
    • Steps: Go to Start > Settings > Sounds & Notifications > Notifications
  • Customize your push email synchronization interval. Manual synchronization will save the most battery life while As Items Arrive will drain the battery more quickly.
    • Steps: Go to Start > Programs > ActiveSync > Menu > Schedule
  • Stop unnecessary programs that are running in the background or soft reset the device periodically.
    • Stop running programs: Tap the Task Manager shortcut (drop down icon in the upper right corner of the Today screen). Select desired action from drop down menu.
    • Soft reset the device: Insert the stylus into the reset hole located on the bottom of the device.
Why does it take so long to charge my device using the USB? more
The USB cable acts as a trickle charger so it will take longer than if you were using an AC charger. While the USB will work, it is recommended to use the AC charger, especially if the battery level reaches 10% or below.
