5 steps

Switching off your device
Turn off your device by holding down the power button until the “slide down to power off” message appears.

Slide your finger down over the screen until “goodbye” appears and your device is shut down.
Removing the back cover
Carefully disconnect the back cover from the enclosure frame. At the bottom, there’s a small slot where you can insert your fingernail or a tool.

Gradually disconnect the back cover from your device.

Take the back cover off of your device.

Removing the battery
Use your finger to lift the battery out of the device. There’s an indentation in the middle of the chassis where you can easily lift the battery.

Remove the battery.
Inserting the battery
Put the battery back in your device.There are three parallel slots on the bottom of the battery. The contacts are in these slots, so they have to line up with the three gold contacts in your device.

When the battery’s positioned right, it will be level with the enclosure.
Attaching the back cover
Put the back cover back on.

Use your finger to press it onto the entire frame so all the clips on the back cover click into place on the enclosure.
