What was the age of the iphone?That is assuming the swelled battery didn't damage anything Steamer861. You still need a heat gun to loosen the screen glue to pop off the screen to get to the battery. On eBay, the batteries are just 4 bucks with free shipping. My Samsung phones I just snap off the back and slide the old battery out and insert a new one. It takes like 10 seconds. That is a much nicer system.
