Grab one of the outer battery adhesive tabs and slowly pull it away from the battery, toward the bottom of the iPhone.

Pull steadily, maintaining constant tension on the strip until it slips out from between the battery and the rear case.

The strip will stretch to many times its original length. Continue pulling and re-grab the strip near the battery if necessary.

If the battery adhesive tabs break during the removal process, use your fingers or blunt tweezers to retrieve the remaining length of adhesive, and continue pulling.

If any of the adhesive strips break underneath the battery and cannot be retrieved, try to remove the remaining strips, and then proceed as instructed below.
