I described the problem in an early iPhone 12 Diary piece …
When the phone arrived, it charged happily on all three of my Choetech chargers. On Saturday, I realized it hadn’t charged overnight, and now wasn’t interested in charging on that stand. It still charged on the other two.
Later in the day, it stopped charging on a second one. Then when I tried the third, it had stopped charging on that too!
I tried all three with and without the case, without any difference. So now it doesn’t wirelessly charge at all on any of my chargers.
Subsequent Googling revealed that I wasn’t alone in this experience, and that it applied to a wide variety of charging pads and stands.
Restarting the phone solves the problem for a while, but it always returns within a day or two. I initially thought that an iOS beta update had cured it, but I was wrong: the problem took a little longer to reappear, but then it was back to regular restarts.
Apple didn’t respond to a query about it, but a 9to5Mac reader was told in an online support chat seen by us that the company is aware of it and is working to resolve it.

Apple: Ok, I do understand your concern We are working on this and it will be resolved in upcoming days.
Reader: So Apple knows that this is an issue?
Apple: Yes we have been going through the issues which customers are facing […] It will be resolved soon.
It’s likely the iPhone 12 wireless charging problem will be fixed in an upcoming iOS update.
