I’m back! The battery lasted about 16 months,. 2nd time went a lot smoother, particularly since the adhesive behind the battery was now much less. The replacement battery-only did not come with adhesive at all, so I just didn’t use any this time. I ended up just replacing the back to go along with it so I wouldn’t worry about cracking it and it was much easier.

Highly recommend against doing this. Even going carefully and reheating, 2 of the corners cracked when moving the pick through. So much for taking perfect care of the phone for 2 years =o(

Just received this kit and I see it comes with the big adhesive, but it also has a smaller blue adhesive and a rectangle thing(that I think goes behind the battery?) that has a small one with it. Where do these things go?
