Try not to wrinkle the strips during this procedure—they will become very difficult to deal with and will not straighten out again.

Pull one of the adhesive strips straight out, towards the bottom of the iPhone.

For best results, pull the strip at a 60º angle or less.

The strip will stretch to many times its original length. Continue to pull steadily, re-grabbing the strip closer to the iPhone if necessary.

Continue pulling until the strip is fully removed.

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

If one of the adhesive strips breaks under the battery during this procedure, and cannot be retrieved, remove the remaining strip, and then skip to Step 48.
