iPhone 12 Pro Max I came across an odd behavior with my iPhone12 Pro Max and wireless charging.

This was repeatable. I typically use the magsafe charger; that being said my wife had gotten a q-charger multistand from a consultant (wirelessly charges a phone, watch and airpods), and so I figured I'd give it a try. The wife doesn't use or have any of the others so it was going to default to me if we kept it. I used it overnight, and everything charged fine. Later I put my phone back on the magsafe charger I normally use, and noticed it wasn't charging. I took off the case, and it still wouldn't charge. I placed it back on the q-charger, and it also would not charge the phone. I thought something went wrong, or there was a hardware failure. On a whim I rebooted the phone, and when it came back up, it would start charging again on the magsafe. I repeated the cycle, of magsafe, q-charger, back to magsafe, and sure enough, if it is made to swap charging methods, it shuts down all wireless charging until a reboot. Anyone else have had this issue show up?

Having this issue since lauch day believing it would have been fixed by software on 14.2 or later.
Now on 14.4 same problem with Magsafe
THIS could be hardware defect.

Don't have an issues with mine. Must be hardware.

I’m having this issue still on my 12 Pro Max on iOS 14.4 software maybe?

I also wanna believe its a software issue since a restart does solve the problem for a while.

I turned off Optimised Battery Charging in the Battery settings and so far wireless charging is holding up. Can anyone confirm the same?
