Wow. I was wondering today if I needed to install a different browser to prevent my phone from heating up as much. So, if you download Adblock on the iPhone, it just works on the browser? I use it on my iMac and it works really well. Not sure how it works on an iPhone.
Via Safari extensions in Settings.

Yeah, I got a message while transferring over data that it had to cool down before finishing. It eventually finished and it’s fine. But I’d never seen that message before.

Used it for a day now and it gets really hot sometimes when seemingly not doing a huge amount. Browsing the forums here the top left rear gets hot to the touch. Not had this with my previous 12 pro or any iPhone before it. Can then feel it warm in my pocket.

iOS is likely indexing (even after a restore or transfer) things like content, Photos (faces, etc).

This will continue for some time and it should get better, but, also, modern phones are thin, have bigger and bigger batteries in them, and have and less and less free space/ventilation, so even with process improvements on the SoC and thermal improvements, they're going to get hot-ish. Basically, manufacturers will push the thermal limit until "ouch, I can't hold it", because if they did not, they are leaving battery life, performance, or form factor improvements on the table.
My battery is also going down quite quickly so I suspect it must be doing indexing or something similar that won’t happen often. It better be, or there is something wrong as my old iPhone X doesn’t ever drain its batteries as quickly (or get as warm).

I wonder if there a bug in iOS15? I can’t imagine they could have missed something this significant.

My non-max pro was really warm when I woke up this morning. I checked my battery and it looks like Mail.app was on in the background all night. Is this just some sort of indexing thing, or a bug?

Not a joke. Some adverts are able to use your device as a node in a cryptomining farm. It ruins your battery. Not 100% sure that’s what’s happening here but it seems likely.
Yeah I’m noticing it on safari. Especially on here. It’s safari taking up my battery and putting the heat on

Not gonna lie, I read about this on another post in an MR thread. I’d been MR browsing for like an hour when I noticed how warm the back near the volume buttons were. after about an hour of browsing it settled. I have no doubt it’s doing stuff in the background. I would wager fresh installs don’t experience this but just a hunch obviously.
In saying above, it’s completely cooled back down whilst doing the same thing (browsing on safari).
what’s even weirder is it didn’t heat up like when playing Genshin (i don’t game on mobile - but wow what a graphical show piece for the max!!)

I’m also experiencing a hot top left area on my 13 PM when browsing MR. Hopefully just some bug that’ll work itself out. I then wiped Safari data and cache and reinstalled AdGuard since I hadn’t set it up after restoring from my 12 PM. Maybe it was AdGuard acting up, who knows. Will keep monitoring.

I use Purify ad blocker and my phone doesn’t heat up at all on MR. Its really hard to go back using no ad blocker -the ads are overwhelming
What are your blocking settings? I have it too but my phone is hot on MR.

Mine keeps getting extremely hot and pausing the iCloud restore process. I've never experienced this with any iPhone.

I got the same temperature warning message. My phone was also getting really hot during my iCloud restore but after that it’s been fine ever since.

MR website and forums are crazy loaded with ads etc but at home i have a pihole which takes care of everything so i don't see any ads or anything but still whenever I visit these forums ir the main site my 12 pro max gets very hot. Something shady going on with this site. As soon as I leave the phone starts to cool down

Can’t believe it worked? Wow didn’t realise ads do that much to our phones. Kind of scary how intrusive/power hungry they can be.

Are you browsing MR forums on said 13 Pro Max while it's copying files over? I know it sounds silly, but my 11 Pro Max heats up like crazy when using MR forums on mobile and it's not just an isolated incident. There's a forum post about this somewhere on here and other users have noticed the same thing. MR forums heats my phone up so badly that I only use them for a few minutes at a time or just use my iPad/Mac to browse the forums. Again, sounds funny, but it could be playing into why it's so hot.
That’s all the trackers on this site it’s crazy

This. Is. MacRumors.

On Safari.

My 11 pro was getting hot(like SUPER hot) after getting the battery replaced last week. Then my 13 Pro was getting warm and draining battery. It was always from browsing macrumors.

I tried using Brave browser with macrumors for an hour this morning and no issues. Switched to Safari and the phone was on fire within 5-10 minutes.

Since all the blocking on Brave wouldn’t even keep me logged in, I just downloaded “Wipr” Safari extension and it works like a dang charm. Been on Macrumors for 30 minutes and the phone is still cool to the touch. Can highly recommend.

It is not the phones fault, it’s our annual pilgrimage to this site and our relentless checking it that is ruining faith in our new phones.

What a Catch-22…

I did a fresh install in my case and am seeing the issue. I suspect that others are spot on and the phone is doing indexing in the background. I have a huge amount of photos that were downloading once I enabled iCloud photos.

I don't buy Indexing. This has to be with Pro Res, the more d]fater you scroll, the quicker and hotter it will get . Bring your brightness to less and for F88 sake, scroll slowly.

It's surely possible it's heat from a higher frequency display operation, but you'd really have to be scrolling *a lot* or playing a game.

OP seems to say operation was just copying data, at which time the display is likely not cranked to 120Hz, but who knows, maybe OP was copying data while playing a 120 fps game!

However, as much as you may not "buy it", heat at that part of the phone is RIGHT at the SoC and indexing on new devices/fresh installs is definitely a thing (just trace md* processes if you don't believe me, and look at what files they have open, you can't deny that). OTOH, heat from a display updating itself more may load the GPUs in the SoC more, sure, but it's also going to drive more heat out of the display, the circumstances don't seem to be lending themselves to a ProMotion related issue (I am assuming you meant ProMotion, not ProRes).
