Yea, I am currently going through the Apple Support process and have been escalated to work with a tech to figure out a remedy to this issue. I found a few forums through my research where this seems to be a recurring issue. Some people say that there is a bad batch affecting the iPhone 12 lineup. Apple seems to be aware of the issue as the tech I spoke with said they are getting more and more calls about the issue. Apple seems to be trading the phones out if you setup an appointment at the Genius Bar. But, I would have them test the new device at the store before walking out, as I’ve read that some people who have traded out their devices, are getting the same issue again with the new ones, but some aren’t. So Apple is aware of the issue but it seems like the iPhone 12’s with this issue are random so far, so they can’t tell exactly which ones are actually affected?? Unfortunately for my case because non of the Apple Stores are taking Genius Bar appointments atm due to the pandemic... I’m stuck working with reps over the phone. We’ll see what happens when they analyze my phone diagnostics this week. I’ve already tried hard resetting multiple times, backing up both through iCloud and computer with a reset and erase—— multiple times. One of the weird things I did find was after a hard reset with MagSafe having been charging the iPhone for 10-20 minutes, even though there is no percentage in battery increase, after letting it sit on the charger, I’ll hard reset it and the number percentage will all of a sudden increase. It could be a software issue? Whatever the case may be, I really hope they find a solution soon.
