So I ordered a battery and screen adhesive from ifixit so I can replace my iPhone 12 Pro battery. [br]
[br]
At first boot with the new battery, phone reported black screen with "battery needs charging" icon. Alright, plugged it in and it started no problem. I read that sometimes the phone needs charging juice to turn on.[br]
[br]
It turned on and reported 60% something percent charge. Alright, following the battery calibration guide on ifixit website and on the battery's box, I left the phone to charge until it reaches 100% and leave it charging for at least 2 more hours. [br]
[br]
Done so and came back after 6 hours to phone stuck at 94% charge. Battery optimization was enabled at the time. There was no mention of this feature in the guide. I disabled battery optimization and put the phone to charge again. Came back after 2 hours and phone was still stuck at 94% charge?[br]
[br]
I force restarted the phone while it was charging and it showed 98% charge. Cool. I'll leave it to charge to 100% then. Except... it didn't charge...[br]
[br]
It stayed at 98%. I thought I would have to drain it completely and charge it back up so I started using it until it would shut down, no problem. Came back home and phone went to 0%. Cool. I left it to charge overnight and in the morning I woke up with 70% battery. When I unplugged it, the % started to go down about 1% every few minutes. Strange... Plugging the phone back in told me it was charging but the % was still decreasing. Force restarted again, it showed 94% battery and it started dropping fast again.[br]
[br]
Now I'm in the situation where I think the ifixit battery is low on charge and the phone refuses to charge it. What else can I try? Is my ifixit battery DOA and I need to get a new one (and new screen adhesive)?
