I have the same problem. Have you found out why it’s doing that?
nope. I restart and the problem seems to go away for a bit and then starts happening again.
It is not about defective devices. It is about Apple’s stubbornness. Each year , they introduce faster and faster and more powerful chips with bigger screens, but they are not thinking about cooling at all. Their only solution to heat as always is the stupid passive heat dissipation. Now with big demanding screens and resolutions, powerful A14 and no form of active cooling, the phones does this so the chip run cooler which is the dumbest solution ever. I pay to use my stuff and not to put it in my pocket after 5 mins outside because the phone cant cool itself and makes the screen pitch black! We are in for a “ treat” with the 13 pro and pro max ! They will be even more powerful, with bigger batteries and with AOD and 120hz and guess what, still no active form of cooling! Who gives a crap about having the fastest rocket chip in a phone if i cant even use my screen for more than 5 mins gaming or 10 mins outside in the sun. Apple are absolute ignorants on active cooling matter! What is the point to put this space rocket power inside a tiny phone and such good displays and everything if you cant even use it in the summer. Who cares that it can go to 1200 nits brighteness outside when after 4 mins it gets pitch black. Sort your hardware Apple.. cause right now… we have the most powerful phone on earth that we can just read emails with or it will dimms the screen cause it wants to stay cooler. Go figure!
