I technically have AppleCare+ on my iPhone 12 Pro Max. I am aware that Apple does not replace it for free unless it drops below 80 % health. However, it is currently at 86 % and the battery is pure crap. I woke up at 7 am this morning with 94 % battery life and now it is at 62%! by 8:50 am. I honestly don't care if I have to pay for it. I just want to get it replaced. Especially since I am going on a trip soon.
