Always the same every year. New iphone full of software and hardware issues, completely unusable according to the press. Keeps selling like hot pancakes, no one has any real problem with theirs (and if they do they get a replacement)

If iOS wasn't just a baby OS but instead had an activity monitor, we wouldn't play scavenger hunt, but instead just see "oh, this app or process is pinned to 100% for 5 minutes, please fix the app or apple please throttle a simple picture viewing app like instagram before it turned my brick into a stovetop". I guess we have to wait until daddy apple with their full system access can reproduce it and fix in 17.1
First of all, the phone does tell you which process is responsible for burning energy. It’s not necessarily the best but it’s there. If the phone is getting too hot to hold though, it’s not a software bug of something pinning the CPU. The OS should be thermal throttling well before that happens, and I’ve seen that happen on hot days (the phone goes from thermal throttling the CPU to a perma “this phone is too hot” bl…
But also some programs shouldn't be allowed to go full blast when they are stuck in a self inflicted loop while waiting for something (instead of doing actual compute). And that is what I meant with activity monitor. If such behavior from popular software was more obvious, CPU waster could be helt accountable. Maybe you may even delegate a program to only use a single core or only e-cores. But instead, I guess, we have to settle with a thermal limit of 30°C so we won't even notice if an open app eats through our battery in the background.
Thermal Conductivity I wonder if this is related to the use of Titanium and the poor thermal conductivity of Titanium (17 W/m-K) vs. Aluminum (210 W/m-K). Aluminum dissipates heat more than 10x better than titanium. https://waykenrm.com/blogs/titanium-vs-aluminum/#:~:text=All... . --- EDIT: I no longer think it's thermal conductivity due to the change in metals. See below. https://news.ycombinator.com/item?id=3770515…
The amount of titanium in the iPhone is about a 1-2mm band around the outside. The inner chassis is still aluminum, and they are diffusion bonded together. While that Ti is at the primary thermal boundary for the metals in the phone, I would guess (judging from experience with both stainless steel and titanium banded phones) that most heat escapes through the glass front and back of the phone, even though they have p…
Some does, but given glass' very poor thermal conductivity (1.38 W/(m·K)), heat dissipation by the band around the outside is probably a very significant factor in total heat dissipation.
I have a 15 pro here for testing, it was fine yesterday, or maybe I just didn't notice it because i wasn't handling it so much, but today, it is very warm (After being idle for 30 mins, not plugged in or anything). Also, the framerate on our AR app is worse, XCode debugging navigator isn't telling me the fps, but compared to a 12 pro, it is noticeably jittery
I've had that experience with some of my testing devices. For the jailbroken one, I can SSH in and see what's happening, and I recall that in at least one case it was an apple process that was sitting at 100% (I think it was springboard, but it's been a while). I killed it and it restarted automatically at a more reasonable 0-3% CPU load. For the non-jailbroken devices, I just reboot them if I notice something is off…
Hopefully fixable with a patch.
Why is weight even a concern? Thinness I get because that makes a real difference in your pocket, but what's the point of reducing the weight a tiny bit?
The hottest I got my iPhone pro was charging it with the Camera app on (this would make any iPhone warm even my iPhone pro 24). I don’t think it’s a thermal conductivity I think it’s workloads.

FWIW, this has been one of the worst seasons for mobile phone sales in a decade. [1] It may be telling if the latest from Apple will change that or not. [1] https://www.cnbc.com/2023/08/17/global-smartphone-market-to-...
A related issue exists with M1/M2 Pro and Max chips in their laptops. They do not overheat (unless you're in a hot environment) since they have fans and seem to have included enough cooling for these chips, but you do not get the miraculous battery life with these that you do with the lighter versions. I guess they made the chip and RAM a lot bigger but didn't make the battery much bigger. The battery life is still d…
GSMArena bought two iPhone 15 Pro Max from different retailers to test the overheating issue and they were unable to replicate it. > Lastly, we did read reports of overheating iPhones, some during fast charging. For this review, we used two iPhone 15 Pro Max units, obtained from different retailers, and neither of those became unbearably hot even after an hour of GPU stress testing. Warm, rather unpleasantly (but not…
> Warm, rather unpleasantly (but not concerningly) - sure, but hot - never. If only we had a standardized scale to measure and express warm vs. cold…
