That’s an interesting theory. I’d like to see some numbers because I really doubt that this heating could be anywhere close to the many other kinds of heat produced through normal phone use. Especially considering that you’re unlikely to be stressing the biggest sources of heat in your phone (the screen and the processor) while it’s sitting in a wireless charging cradle. Also, the charging circuits certainly monitor and adjust for this kind of heat dissipation specifically and are able to control it far better than, for example, the sun hitting the screen or a warm pocket.
I remember LTT wanting to find out the damage that wireless or fast charging does but found that the way we charge our phones mattered more or something: https://youtu.be/AF2O4l1JprI
I found the segment and may have summarized it incorrectly but I can’t rewatch the video entirely right now.
I can only offer you my experience-based evidence, but three magnetic chargers I’ve used have all made my phone significantly hotter then charging it at the equivalent speed with a cable.
This has been true across 6 Android devices. Two from Google. Four from Samsung. However, I will also say that because of this trend, I stopped using wireless chargers about a year and a half ago, so it’s quite possible they might have improved since then.
