Sitting in my car charging by wire. Picked it up and saw this.

Thermals aren't going to be as good on an ultra thin phone. If you've never seen this message before then that's most likely the cause.
 
Always fascinating to read these comments, as I know that climate makes a huge difference.

I’m from the U.K and I’ve only ever experienced an ‘over heating’ warning once; it was during a garden party where I left my phone on a table for a few hours in direct sunlight.

Can’t imagine what it must be like to use an iPhone in a desert.

Last iPhone that didn't overheat was iPhone 5 for me. When my battery was good on 11 Pro it didn't seem to do that either, but as it degraded to 90% I've noticed that it started to heat more.

Btw, using iPhone with no case helps a lot. Also try low power mode+60Hz refresh rate.

It also depends how much watts iPhone sucks during charging. The last non-overheating limit was 12w, and iPhones nowadays would probably get up to 40w which is a lot
 
Wonder if placing the phone on the cool side of a Peltier plate would help?
Well there's a cool (har har) idea! Glue a Peltier to your car's phone mount. Only challenge would be powering it. And it turns out that's not much of a challenge either as you can get a 12v Peltier from Aliexpress for a whole $2.35:

My 16PM does this sometimes.
Almost always when it's plugged into CarPlay, running Maps, and streaming music—especially if I don't hide it from the sun in the dash.

But you do you.

We learn not to leave our phones in the sun or in tight pockets when it's really hot.

Never been an issue for more than a minute or two.

I live in Phoenix.

It’s not exclusive to your iPhone Air. Everyone on iOS 26 is overheating. Hopefully the optimizations will come soon in an update.

Has happened to me while I was in my car, because it was a sunny day and that warmed up the phone. It wasn't at all related to the hardware (not an Air) or the software (not iOS 26).
