This isn't a problem it's just how wireless charging works when you run a bunch of other stuff at the same time. Your phone is using more battery than it's charging with so it pulls full amps from the charger for extended period of time and overheats. Literally all wireless chargers will do this.
Personally I think the wireless charger is great and one of the features we bought the car for. Works flawlessly for us using iPhone and Android.
I’d also have to disagree with this statement somewhat. I agree a phone can overheat with wireless charging especially when it’s under heavy load I.e. multiple apps and background processes running.
…but I have many wireless charges that I use in home and they do not cause this same level of overheating and slow/lack of charging.
I leave my phone on a wireless charger all day while working and it chargers much faster. I am constantly playing music from it and getting over 300+ email notifications and heat is never a concern.
with that said, the GCL wireless charger is incredibly slow and overheats way too much. You’d expect that if the heat was from a higher watt chargerthen why the incredibly slow charge?
also, running newest iOS 15.1 on iPhone 12 Pro Max.
I guess the only outlier I haven’t tested is wireless CarPlay. Is that using so much process power that while charging wirelessly its heating up? Doubtful given my phone is connected to it every time I’m in vehicle and there is no heating while charging with a cable or when I’m home and connected to WiFi and using a wireless charger.
