Apple support says that the company is working on a fix for the iPhone 12 wireless charging problem experienced by a number of owners when using Qi-certified chargers.
I described the problem in an early iPhone 12 Diary piece …
Subsequent Googling revealed that I wasn’t alone in this experience, and that it applied to a wide variety of charging pads and stands.
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.
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.
It’s likely the iPhone 12 wireless charging problem will be fixed in an upcoming iOS update.
