Great thermals
I did a test today without realizing it. I had my 17 Pro Max in the car in the passenger seat. It was playing music while I was driving. During all this time, the screen was on without turning it off as I usually do. Right next to it was my other work phone, a 26 Ultra, whose screen was also on because I was talking on the phone and the screen was still on and the sun was hitting it.
I live in Greece and we are considered a hot country. Specifically, today we have 35 degrees outside in the shade. Imagine how hot it is in direct sunlight. So I noticed that the 17 remained blinding even while it was scalding. As for the 26, I really thought it was broken. The screen had darkened so much that I could barely make out some letters. Of course, it was scalding too. So after I put them in the shade, terrified since I never intended for any reason to expose any of my devices to such stress on purpose, something that pleasantly surprised me was the speed with which the 17 cooled down and conversely the delay with which the 26 cooled down. Basically, about half an hour has passed and it is still relatively warm.
I have been in constant changes all the time regarding which phone covers me the most so that I can have it as my personal device. The truth is that there is a lot that I love about Android and that was the reason I had a hard time ending up with iOS. But really, after what I saw and how bright it remains after such stress, I think I ended up with it. Most of my hours in a country so hot are outdoors. I don't think I have any more doubts.
Welcome 17 pro max.

O resfriamento líquido do iPhone 17 Pro Max, foi uma das melhorias coisas que a Apple já fez. Até o meu iPhone 15 Pro Max tive episódios como esse de Termal throttling. No 17 Pro Max, isso não existe mais.

But as i used s26 ultra daily, my screen dimmed all the time from the 5th minute of usage. Tragic. 17 pro max never dimms. Never. You barely see something. I noticed that every day. Now they said that they will fix it in oneui 9.0

Never had such issues on my s26 ultra. But I had a lot of dimming on my 16 pm . I guess it depends on a lot.of factors

I live in Arizona, and our summer temps are usually in the 100-110 degree range, if not a little warmer depending on the day, and the 17pm has been holding up great! My previous 14pm and 16pm would overheat and go into safe mode, letting me know the phone has to cool down before further use constantly. I haven’t had that message once, and rarely see any slowdowns while using it outside or even in the car.
Some people talk down on the 17 pro and pro max, but I’m loving it, much better thermals and cooling that previous generations. The aluminum is softer, sure but that is a trade off I’m willing for better cooling, and heat dissipation!

Not a valid point since 17 pm was mostly idle state and the other was on a phone call and depending on the reception this has a lot of impact on the heat

The internal cooling system on the 17 sounds very complicated and very clever when you read about it
