The first white strip ripped right off before any of it pulled loose. I was extra careful with the second one and got 2/3 of it off before it broke. Heating the back side of the phone probably would have helped. I didn’t think there was any hope of getting the battery out until I read the comments here. Here is what I did, I took an iron and used it to heat up a 5 lb metal weight so it would stay warm for a while. I put the phone on the heated weight to keep it warm. I took dental floss and worked it under the battery to try and work the white strip loose. At the same time I used a plastic credit card/door key to work the battery up from the side. I eventually worked the plastic card under the back edge and worked my way deeper in until I was able to get it loose. When I got it loose it looked like the white strip was wadded up underneath the battery. I don’t think I had a chance of getting the strips up by just pulling.
