Wow. Good luck removing your battery by this method. The adhesive on mine was impossible to remove, finally the battery foil peeled off, the battery was totally destroyed, and I had to scrape the adhesive off the phone bit by bit. Scary to abuse a lithium battery that way… Destroyed my ribbon cable, too, so now I can spend another $30 and a bunch more time… Wow. Not recommended; impossible to accomplish as described. Battery is not removable. Those adhesive strips are from !&&*. There is no reason to use that adhesive in that location, except to deliberately make the phone non-serviceable. Once the adhesive gets old, it just snaps and heat doesn’t help. Good luck.
