46c… lmfao what a stupid headline.
That is absolutely NOT “hot”or “overheating” for a piece of tech under stress.
The phone housing is the heat sync, and the phone is more powerful than many people’s few year old laptops.
Not to defend apple but this is just trying to sensationalise and farm clicks, my pixel 7 used to get way hotter doing just normal tasks to the point I was getting overheat warnings and the screen would shut off.
Now if it was more like 55c I could see that being an issue at least from a comfort standpoint.
On top of this, pointing a thermal camera as an emissive surface like glass… not the most accurate way to actually get a temperature reading, they should have used a thermal couple… but I’m guessing that would have showed an even less exciting click bait number.
It is not comfortable to hold a 46C metal object in your hand.
but it looks so cozy
It depends on how you're holding it and how spread that heat is. 46° isn't something great to be grasping for extended periods of time, but if you're physically touching 30°C parts of the phone and a part with no physical contact with your skin is 46°C, it's probably not that bad.
My s7 edge used to hit these temps. The annoying part was the throttling and shutdowns. I never really felt like I was burning my hands using the thing.
Excuse me, but this has "you're holding it wrong" energy. And according to this page, 44°C is starting to feel painful to touch, and 47° is enough to cause 1st degree burn.
Proteins and enzymes begin to denaturate at temps >40°C, that's why a feaver exceeding this temperature is dangerous and why we feel a warning pain at 44°C.
It’s not “overheating” either though is it?
46c is not that hot at all, that’s like half as hot as a cup of coffee.
It’s probably not ideal.. but also not at all new and about the same as my S22 ultra hits under load or when charging which runs far cooler than my previous pixel 7 which would actively overheat if you tried to run maps while charging it on a warm day, to the point it would force the screen to min brightness after about 30min.
Yeah, I've had overheating issues while running maps and charging on older iPhones too. Not with Apple Maps but with third party mapping software that pushed the CPU/GPU a little too hard. Doesn't tend to happen on modern hardware with mature mapping software.
Also, iPhones do a lot of computation on your photo library while charging. They do things locally on device that Google would do in the cloud. Combine that (for years of photos and not just the ones you took in the last day or so) with normal heat from charging the battery and 46°C seems pretty reasonable to me.
I get where you’re coming from, but just because it isn’t hot when compared to a full throttle desktop CPU doesn’t mean it’s good for a device you hold with your bare hands.
Can you name one other thing in everyday life that you hold for hours on end, that gets 45+°C?
Udon straight outta the pot while I try to slurp it down?
I'm a slow eater okay?
Actually it can pose quite a big problem. There's no ventilation on phone anywhere and lithium batteries really don't like heat, at all. In fact that's just at the top maximum battery can take, so there's a big chance of thermal runaway at which point whole thing might combust.
Lithium batteries aren't going to thermal runaway at 46ºc.
Edit: I looked it up. it's ~66º, so maybe closer for comfort that one would like.
Yup. Not that far from recorded temps. Combine that with leaving phone in car or in direct sunlight and you enter dangerous zone.
iirc iphones at least turn off if overheating so they might just be fine in that regard. sucks to get to your phone in the other room and find it turned off tho ig.
Those situations are best avoided. Fail safes are there to prevent catastrophic failure, but heat does affect things permanently. Your battery life will take a big hit. CPU might not like it, etc.
Look here, apple fan boy. You can try to piss and moan whatever way you want, but if you read the article you'd see this was happening while charging or just watching videos and doing "light duty use". A 116f case is absolutely not normal for that. My three+ year old phone doesn't even get a bit warm doing any of that. If my phone went over 90f from watching videos I'd be pissed. Apple likely screwed something up on their software side and the processor is spinning its gears hard for little to no reason.
It has also come out that there is a bug in the instagram app from what I’ve been reading.
This is causing a drastic increase in temperature and battery use on all iOS devices running ios17.
This could very well just be some app code bug that is caught in a processing loop.
It also explains why some people are seeing this and others are not, as not everyone is sitting on instagram while their phone is on charge.
Please take that common sense elsewhere. Here we don’t defend Apple since this is a general technology community. You are supposed to hate them no matter what. Only if this happens to an Android device, we try our best to understand.
It has a battery directly next to the CPU, you can't compare that to a desktop or Laptop and will take damage FAR sooner, especially conaidering what a pain "modern" smartphones are to repair, even something trivial like the battery almost requires a specialist!
