Battery Indicator

The Battery Icon in the Status Bar shows the battery
power level. When battery power is 15% or less, your device
prompts you to charge the battery. If you continue to operate
the device without charging, the device powers off. For
battery use information, see “Battery” on page 136.
Warning!
Use only approved charging devices. Approved
accessories are designed to maximize battery life.
Using other accessories may invalidate your
warranty and may cause damage.
Important!
You cannot charge the battery using the USB cable
and your PC.
Note:
If the battery is completely discharged, you cannot turn
on the device, even with the USB power adapter
connected. Allow a depleted battery to charge for a few
minutes before you try to turn on the device.
