OK, I got my adhesives in yesterday and I was able to complete the project. It powered up and everything looked good, home button functions, fingerprint scanner works. Only one small weird issue though. I let the battery drain to below 10% then charged it. I waited all night for it to get to 100% but at 97% I fell asleep. I woke up early in the morning and saw that it was still at 97% and thought that can't be good but forced a reboot and when it came back up it said 100%. Anyone know what that means? I took it off the charger and used it some this morning and it seems to be draining. My original reason for replacing the battery was that the battery percentage would be completely wrong, most of the time it would get stuck at 100% but then suddenly die. I believe that using the Apple smart battery case may have been a contributing factor to this. The battery didn't seem to wrinkled when I installed it. Could it still swell up if there is a problem?

I attempted this last night. I got the left side of the battery adhesive to come out in one strip but the right side broke. I used a credit card and dental floss to get it free. I thought the battery removal would be the hardest part, but it turns out that applying the adhesive would be. I even watched the video. Still failed.

So, I was determined to get the project done. I went to home depot to look for double sided tape. I purchased double sided foam tape. I put it in and discovered it was too thick. I then panicked because the battery was stuck in and I didn't leave myself much slack on the left side to get a credit card in.

I tried to remove it by gently prying from the bottom left but noticed it wiggle so I decided that wasn't safe. I finally was able to successfully remove it again but I'm worried I may have damaged the battery. Is there any way I can know that the battery is safe to use?

I ordered a 3 pack of adhesive so I've got 3 chances to get it right. It should be here tomorrow.
