I do think "normies" care about the CPU is hot or not, but they do so indirectly, as the phone will start throttling the CPU when it reaches a certain temperature, so the phone will start feeling laggy.

If you've ever tried to play a game on the iPhone/doing something else CPU/GPU heavy while outside in the sun on a hot day, you'll know what I mean, the performance is much worse.

Once I've had it outright shut down and show a black screen with a pretty thermometer, how's that for "performance is much worse"? ;)

(to be fair it was a spectacularly hot and sunny day, definitely in the "out of spec" range)

good excuse to put down the phone and enjoy the sun :)

Some of us live in places where there is more sunny & hot days than not, and your advice feels geared towards people who don't live such places ;)

I'll add that in some places sunny and hot days are sometimes better spent indoors with an aircon if possible.

Excessive heat, especially in humid regions can be daunting.

Summers in my country are getting hotter and sunnier and they've had an impact on my screen use (I hate glare!).

Absolutely, I have the 12 mini, and if my phone is plugged into my car while using maps + Spotify, it shuts down to prevent overheating.

Haha, I have exactly the same problem with my iPhone 12 Mini too, except I use Waze and YouTube Music with CarPlay, and it only happens on hot summer days, although it was in the shadow.

My hack was to put the phone so I could aim one of the AC outlets straight at it, which solved the problem.
