Wireless charging issues with iPhone 12

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.

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.

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.
