I am in no way an expert, but I believe low power mode stops backround tasks, wont automatically download mail, etc.
I have seen anything that makes the processors slow down or just runs the efficiency cores.
Got a tip for us?

My 12 pro got hot and shut down when I played music and used my camera as a dash cam otherwise that was OK
Is there a Lamborghini model with a 6-cylinder engine? There may be no need, but are you the only one not needing that?
@IGWT15
According to 9to5Mac it is across all 15's though there have been more reports about the 15Pro/ProMax.
Can you show me where moving from 3.46Ghz to 3.78Ghz for the two P cores can be seen in a demonstration?
I just love it how people think Apple didn’t test this design and they just slapped some aluminium inside without thinking about thermals and are now surprised od something.
Obviously, thermodynamic experts and super engineers that frequent this forum will now explain how they made a mistake and “what Apple should have done”.

I was going to order a 15 Pro later this week, but I'm going to hold off for now - I'm waiting to see if Apple at least acknowledges the issue.
Just FYI AT&T has a 14 day return policy. You can call them and they send a prepaid return package for free or you can go to any AT&T store.
I want no part of this heat issue with my 15 Pro and mine almost burned my hand on a Diablo session. It got better after indexing finished but it’s still a big issue for me.

Makes no sense that thermal compromises are causing the issue as the heat comes and goes with low cpu/gpu activity. Yes the titanium is probably not helping but this is a runaway process or something that is causing much of this issue.
“We think our customers will love these new iPhone 15 Pro heat resistant gloves”
My theory on their warm flashes relates to heat distribution. Steel is a poor conductor of heat, but aluminum is an excellent conductor of heat. According to the Wonderlust demonstration, the steel and aluminum are integrated only on the sides of the device, but the back panel is all titanium. That would explain the perception of overheating. Like a stainless steel frying pan on a burner, one side of the pan is cool, and the other side will sear flesh. At the same time, the heat source underneath is equally distributing itself. Perhaps the same is true for the new titanium phones?
I don't see any other way software could combat heat other than by slowing things down. Which is not acceptable.
Apple is expected to address the thermal issues through software updates, but improvements will be limited unless Apple plans to lower processor performance.
Did they not test these in real-world conditions?
They didn’t test restoring from a multitude of iPhone configurations- I doubt this is mostly hardware. My iMessages aren’t indexed- if that is going on without pause and not updating that could very well be the problem
So... like literally every other model of iPhone ever, and as far as I know every Android phone as well, and also nearly every Mac and Windows laptop in the world, as well as some desktops?
That sentence is kind of like saying "There have been reports that when used in the dark Maglite batteries drain, and some tests have suggested that when this happens the light gets dimmer." It's not something you need to speculate on or test, it's fundamental in the way the dang thing works.
Of course CPUs get hot when they are under load. And of course CPUs with limited cooling throttle when they get hot. That's how a modern phone works.
I haven't yet managed to push my 15 Pro enough for it to get warm, but my 14 Pro certainly did, and would throttle eventually, as would my 13 Pro, and 12 Pro, and 11, and X, and 6s, and 5, and I assume every other remotely recent model of iPhone that I haven't owned, up to and including the 15 non-pro.
For that matter, we have several loaded $3500 Dell Precision 5570 laptop workstations at work. If you push them hard enough, they get hot! And if you max out the CPU for more than 1-2 minutes, they throttle the processor by about 30-40% (at my room temperatures)! So does the MacBook Air! So does EVERYTHING with limited cooling capability and enough "burst" power to heat up! The alternative, if sufficient cooling is impossible, is to hamstring the whole thing so it can never run fast enough to heat up, which is counterproductive and dumb.
The actual question is whether it's worse than previous iPhones. I have no comment on that, other than that in the first few days of use with my 15 Pro I've noticed it getting considerably less warm than my 14 Pro when doing the same things. Cooler enough that I was actually surprised and impressed by it, although it's still early. And unlike my 14 Pro, I haven't seen it throttle at all yet (it was most noticeable before that if it got really hot scrolling would become jittery in a CPU-intensive app I use).
Even when I ran some 3dMark ray tracing benchmarks I was surprised that it didn't heat up as much as I expected it to compared to running games in the past.
My 13 pro max ran hotter than my 15 pro max. Battery life is pretty woeful though. Poorer cellular signal.. down the beach and spotify wont play, black spots in my house are more pronounced with calls failing. Also waiting for a replacement (in store stock) blue 512gb as the telephoto lens had a metal fleck inside next to the camera lens. BUT.. the phone overall feels much better than the 13 pro max. Dynamic island really adds some interaction, and even the little waveform animation on calls or music make the phone feel a bit less static.
Edit - forgot the biggest gripe - screen dimming! You launch a phone with great cameras yet dim the screen whilst taking a photo or when editing in Lightroom. Torture! Give us a toggle Apple!

Does this happen all the time or during specific tasks? I am a light phone user and haven’t run across this.
Could it possibly be some poor programming code in ios 17? Just curious about thoughts on that. Tia
Am coming from a back up. But only having overheating & battery drain on the 15 pro max when making cellular phone calls either regular phone calls or FaceTime audio through cellular. There has to be a software problem. When using WiFi calling, the problem does not exists. Is only with cellular. 30 mins into a cellular phone call it went from 100% to 84%. Then spent 25 mins with Apple support and it came down to like 64% percent and the phone was so hot you could barely touch it.
No problems here either except on day one during setup. I was out taking photos in the sun over the weekend and it felt warm, but not hot like it was during setup. Aside from that, I haven't noticed it getting warm at all, it has felt the same as my 13 Pro.
The enclosure (brushed outside edge) is grade 5 titanium alloy. the substructure (the part inside the phone where everything is attached) is aluminum fused to the outside titanium. The back panel is glass, as it has been for years.
14PM was already hot but yes it's worse here. Today 20 min of gaming (not a big game) and it was very hot around the camera and on all the top half of the phone.
I am sure that phone will love my next vacation .. 14PM already stopped to charge a lot of time but here it will just explode :d
