Try to keep the strips flat and unwrinkled during this procedure; wrinkled strips will stick together and break instead of pulling out cleanly.

Very slowly, pull and stretch one adhesive strip away from the battery, toward the bottom of the iPhone.

Allow the strip to stretch out before pulling any harder. If you can't feel it stretching, ease up, or it will break.

Pull at as low of an angle as you can without snagging the adhesive strip on any of the components along the lower edge of the phone.

Don't press down on the battery as you pull the strip.

The strip will stretch to many times its original length. Continue pulling slowly until it releases and slips out from underneath the battery.

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.
