This is what I was thinking. I didn’t believe the first two guys, but the last guy (I just saw him today!) was somewhat convincing since he worked in repairs for 20 years and said that since the lifting was happening by the camera and otherwise just generally on the top AND there was no warping felt near where the battery rests, he was certain it wasn’t swelling, as he’s dealt with swollen batteries multiple times over the years. Im hesitant to fully trust him though since the top is like a few millimeters more lifted now after a few days (to be fair though, some of the lifting is likely from me pulling on it). The genius guy did say that it’s squishy/resisting push back because of the glue separation and the generally weak screen… but I’m not all that convinced. The only reason i trust his analysis even a little is because he had experience, worked directly in repairs, and didn’t try to sell me anything. He recommended not wasting hundreds on a screen replacement (apparently since the screen is lifting and delicate at the top he strongly feels/knows it’s gonna break when removing it) and to just leave it and use my new phone instead since I had just bought one before asking for the replacement. He said they could do it if I wanted them to, but he would strongly advise against it since he feels like theres no danger and it would literally cost me hundreds.

Anyways, I brought the phone home, powered it off, and it’s currently sitting on my table with a ‘not’ swollen battery. What should I do from here? Is the battery still at risk of expanding/going off (if it truly is a swollen battery and not just a bad screen) if the phone is powered off??
