Slowly pull one battery adhesive tab away from the battery, towards 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.

If the battery adhesive tabs break during the removal process, use your fingers or 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 other strips, and then proceed as instructed below.
