iPhone iPhone 6S overheating while on WiFi issue...

I installed the first public beta of ios13 on my iPhone 6s. It was working fine for days but then I decided to go back to ios 12. So I put the phone in DFU and went back to ios12 via iTunes.

Few days later my phone starts giving me the overheating message on the screen and the top left of the phone was hot. I tracked it down to the WiFi. When I would turn WiFi off the phone would be fine. Within 5 mins or so of WiFi being back on the phone would overheat.

Decided to go back to the 2nd public beta this evening to see if me going back to ios12 had maybe did something, installed after a nightmare few hours as the phone would keep overheating while dowoading over WiFi. Ended up setting the phone on an old PC heatsink to help lol

Anyway, back on public beta 2 and WiFi overheating still an issue. Could this be because of ios13 or has this 6s developed a hardware issue with the WiFi chip?

iOS never has low enough access levels to modify and/or break hardware. I think your observations are coincidental.

It may be that all of your DFU and restoring is requiring your device to re-index all files as well as restore lots of personal data from the cloud, which means a lot of CPU horsepower and in turn heat. If the heat doesn't stabilize after a few days, perhaps its hardware related, but I don't think the software was the culprit.

Is your device out of warranty and AC+?

The phone is only a few weeks old.. If it doesn’t improve I’ll revert back to iOS 12 if I can, and drop into an apple store with it.
