Do you have any of the details from your charging pad replacement? Part numbers or service bulletin? My dealer has looked at the same issue for me but doesn’t know about this potential fix.

Thanks

My new pad now works on my 2020 - gets the proper charging light on the dash - but it essentially doesn't charge the phone. Phone literally shows its charging but the % never really changes.

I’m pretty sure there’s a service bulletin about the issue. My dealership fixed my ‘20 HSE.

I quit charging my iPhone 12 on the pad — it gets so frickin’ hot I can hardly touch it. I just plug it in if I’m traveling for a couple hours or more, of leave it in my pocket for shorter trips. But it works just fine as far as charging the phone, or it did two months ago when I last used it.

Same thing happens with my RS6 - phone gets so hot it starts to malfunction. Doesn't happen with connect via cable

I have the same experience; my iPhone 13 Pro Max charges fine on the pad but gets very hot. Which it does not do on the charging pad on my bedside table. Not sure why

Some reasons for the phone getting hot may have to do with the fact that wireless charging is inherently inefficient, the difference between the technologies employed, such as charging a MagSafe device on a Qi format charger and vice versa, and the use of a case and the material it is made of and the thickness of the case. All my research indicates that the heating is normal and does not affect the life of the device or battery.

I don't have this problem. My Iphone 5S doesn't support wireless charging.

I don’t use a case on my iPhone 12, just straight phone. However, it once got so hot it went into shut down mode, and it was not in the sun at all. That’s when I decided to quit using the Defender wireless charger.

Hmmm, can’t speak to that. I know sometimes I have to shift the iPhone back and forth to find the ‘sweet spot’ for charging, just like my home wireless chargers which are respectively Qi and a MagSafe charger. Articles I’ve read mention that the drawbacks to wireless charging are the difference between a ‘wired’ connection and wireless charging across an air gap are mainly due to the inefficiency of the wireless charge, resulting in higher temperatures. So, my thinking is if the device is not centered on the ‘sweet spot’ of the charger, efficiency goes down, temps go up. Just a theory, I’m not an electronics engineer.
