2 Put the device in a safe place and let the battery charge for at least four
hours with the device powered on.
As the device is charging, the bars in the battery icon fill repeatedly
from left to right. When your device is fully charged, the lightning bolt
icon will disappear and the bars will stop moving and remain in the
filled position.
For efficient operation, charge your device nightly. If you plan to leave
your device unattended for an extended period of time, be aware that the
battery will discharge after two days if it is turned on and not attached
to the charger. If your device does fully discharge, simply attach it to the
charger to recharge (as described in this section).
Removable Battery
To replace your rechargeable battery, or if you need to insert or remove
your SIM card, first you will need to remove the installed battery. Begin by
powering down your device:
1 Press and hold the power button for three seconds to power down.
2 Turn the device over. With the camera at the top, slide the battery cover
to the right by carefully pressing the notched line on the cover with your
left thumb. Lift the cover to remove it.
