iPhone 15 overheating reports, with temperatures as high as 116F::Widespread reports are circulating about the iPhone 15 overheating, seemingly across all models. Measurements taken with an infrared camera show...

139

46.6˚C in normal units.

Stupid us units had me thinking there would be fires everywhere for a moment.

F makes more sense for this. It’s 0-100 on a scale of a human feeling too cold to too hot.

In situations where what’s being discussed is touching human skin: weather, a hot phone, water temp, etc… F does give you a quicker idea of things.

That said, downvote me away!

It only gives YOU a quicker idea because you are used to it.

I don’t deny that. But it’s also a well suited 0-100 scale for weather. It’s rare for a native C person to agree. I accept and expect the downvotes because hurr durr usa is dumb. To be clear, C is way better for anything other than things that touch my skin.

What's this 0-100 scale you're using? Just a personal comfort gauge that you're assuming everyone uses? I'm American and it doesn't even make sense to me. 70ish is room temperature, 98 is body temperature, 32 is freezing. That's a really weird scale which doesn't have any nuance to it especially since temperatures reach above 100 or below 0 in a lot of places. Add on that people like different temps and it's really confusing.

For anyone willing to learn, a lot of devices have conversions from F to C. I have about half of my temp reporting equipment split so I can better understand C since all I personally knew was F. It also helps to have the formula in your head and convert it anytime you see F so you'll slowly be comfortable knowing both of them. (Fahrenheit - 32) / 1.8 = Celsius, usually just do / 2 for a simpler time: i.e. 72F - 32 = 40 / 2 = 20C (really 22.222C but it gets you in the ballpark at least). It's even easier to use the formula since 32 is Fahrenheit's freezing temp so just always minus that away and divide by 2.

Like others have said, Fahrenheit is just easier for us because it's what we grew up with and learned. It has nothing to do with the actual system besides personal experience. Thinking the "0-100" is a scale that makes sense when the bottom 3/4 is colder than comfortable room temperature is just being irrational.

The average temperature in the continental United States is just over 50 degrees while the extreme highs and lows are 100 and 0. Could make an argument that 0 is a bit too low.

Coincidentally, perhaps, but nonetheless you can’t deny it’s pretty good range for temperature of air in the US.

No need to downvote, I can handle someone having a different opinion.

Fahrenheit doesn't give a shit about human temperature, he based it on some obscure things (which I can't remember right now). It doesn't even fit with human temperature, I think human temperature is like 97 or 98 °F or something like that. The argument was made only to have some argument, it's not a property of Fahrenheit.

It does make exactly as much sense as Celsius with one important distinction - Celsius plays nicely with other SI units.

Seriously, the only correct answer to how many foot-pounds does it take to heat 1 fl oz of water by 1° F is fuck you.

I don’t mean it’s body temperature. I mean it’s good for describing temperature felt by a human. The weather is a scale of 0 being too cold to 100 being too hot. The typical person never sees temperature outside this range in their weather, but a good bit of the full range.

When describing weather, you don’t care about 213 being boiling temp and converting to SI. In all Other uses, yes, C is better.

That’s just you being used to the imperial system. I have no problem describing the difference between 0°C, 20°C and 40°C.

I’m not saying it’s impossible to describe the difference in Celsius. What I’m saying is that the resolution is finer, and with the scale of 0 to 100 is quick to understand.

The fact is we like to have a scale between zero and 100 for things. That’s what Fahrenheit is for weather. I understand you don’t agree, but that doesn’t change the fact that it is. I use both C and F. I prefer F for weather.

Honestly, I get your point, but I don’t think it’s necessarily a property of the scale, rather your increased familiarity with it. When someone says 68F I don’t have a mechanism to understand that, it’s not part of my experience. Saying 68% of too hot doesn’t help much at all. Whereas I can tell you exactly what I 40C feels like; and how that compares to anything from -15C to 45C, because of my familiarity with the scale.

Yes, familiarity with the scale definitely helps. But 50 degrees is halfway between burning up and freezing your ass off. Aka, light jacket weather.

And if anyone’s wondering that’s 116°F in more normaler units

Edit: it’s a multi layered joke guys chill. Joke is Americans can’t read, the °F is in the title. The other joke is that American grammar is shit

Lemmy can be pretty hostile to non-European standards. It's weird... I wonder if Europeans are just using more accounts than Americans, and stacking votes.

If not... Then yikes, if Lemmy is losing the American audience, that's bad news, friends.

Celsius and Fahrenheit are both European units. It's just that Fahrenheit is used by less than 5% of the world's population, so it's completely reasonable to expect a post title on an international website like this to use Celsius.

To be fair, the Fahrenheit measurement should be pretty intuitive here. Fahrenheit is easy because 0 degrees is "really fucking cold" and 100 degrees is "really fucking hot." So anything triple-digits should be easily recognizable as "yeah that's way too fucking hot for a phone."

This is also why I prefer Fahrenheit to Celsius in general (even though I am an engineer and am not a die-hard patriot or anything like that). It is a more practical scale for everyday usage.

And Celsius is 0 for freezing water and 100 for boiling water, sounds much more practical to me

Why are Americans so bad at geography 🤦

You do know there's a world outside of the US and Europe, yeah? Like other places are a thing that exist? And guess what - they all use Celsius!

This isn't a Europe Vs US thing. This is a US Vs the world thing, with Americans expecting their way to be taken seriously by everyone.

Don't be surprised when people want to use the actual standard.

It's an incredibly euro-centric view to think that the rest of the world uses the metric system. Heck, even the UK mixes and matches units contextually. Plenty of global industries apply their own standards.

I've never seen an American on the Internet suggest China move from Chi to Feet, for example. Europeans just assume that they use Meters because they're polite enough to just do the conversion on their end for international trade.

You do realise we're talking about Celsius here, don't you?

The UK absolutely uses Celsius, as does the vast majority of the world. To my knowledge it's just the US and Liberia.

There is nothing Eurocentric about saying Celsius is the standard. There is, however, extreme US-centricity in thinking Fahrenheit is the normal one.

Whats the speed limit on British highways?

Is it miles per hour?

Yes, the UK mainly uses metric but for a few things they use imperial or both. For road signs they're mostly imperial - what does that have to do with Celsius?

You're not making yourself look good here by deliberately going off-topic.

Let me begin by apologizing for asking about things across the pond.

Also

Oh no, I don't look good right now?!?! Fuck man it's all over, this was all I had left

Are you stupid? Lemmy isn't hostile to the US. We are hostile to idiots who do not recognize standards. That this includes most of the US is just a coincidence.

Hate to break it to you (and your superiority complex) but Fahrenheit is also a standard.

No it isn't, nobody uses it. I can't sayb"my proprietary unit is a standard that only I use".

In the US.

For me a standard that I mean as standard is globaly used by scientists

Cool, so Celsius is not a standard because it isn't global.

As far as I know even US scientists are using Celsius and centimeters.

Shit man, I use Celsius and I'm in the glory hole of america.

I will say this: fuck imperial-measurement-deciders for naming 1/1000 of an inch a "mil". Fuckin pricks.

We've had enough of USdefaultism over there on reddit.

Yes, every European has at least 3 lemmy accounts, as required by the European constitution.

There are a lot more Europeans online than Americans (not to mention a few billion internet users on other continents), so when Americans post temperatures exclusively in Fahrenheit it comes across as kinda thoughtlessly parochial.

There are a lot more Europeans online than Americans

  1. I don't believe this at all lol

  2. The audience for this is English speakers. While much of the world reads English non-natively, those people often turn to news source in their native languages. If this article were in French, using Fahrenheit would be silly.

  3. Most iPhone users are American. This data shows that just a few years ago 43% of iPhones were sold in the US, with Japan in 2nd at 14% and China at 13%. Even adding up the UK, France, Germany, and Australia they combine for 20%, though once again I'd expect French and German articles fod those audiences.

Europeans just can't handle the fact that colonization is over lol.

Damn, how can a first world country produce so much of this?!

Lol, second comment this morning I've seen someone complaining about their fundamentally incorrect statement is recieving "unfair" hostility...

No, you're just wrong and people downvoted you because of it

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.

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?

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!

Some context:

http://www.antiscald.com/index.php?route=information/information&information_id=15

At 116F you would require firm, continuous contact for more than 20 minutes to produce a 2nd degree burn, and over 45 minutes to produce a 3rd degree burn.

So one semi long YouTube video is all it would take to get a burn? And you’d not even need a full length movie to need a trip to the hospital?

I get that these aren’t “instant” burns, but this is still a device people regularly hold for hours a day. And if you don’t realize it’s heating up, you’re likely to notice only when you’re in pain.

Yea I think that when something is hot enough to cause burns, even when it takes minutes, I think it's uncomfortable enough for people to let go way WAY before anything bad happens. If you don't then you probably need medication for whatever condition ails you

Realistically speaking, since this is in fast charging only, and most people don't let their phone battery drain to 0, I think it's unlikely that 3rd degree burns will be an issue within reason. The iPhone 15's reported to take about 30 minutes to charge from 0 to 50%, so if I assume the other 50% also takes 30 minutes, then really, someone won't be hitting 45 minutes unless they're charging from below 25% to full.^[I know charging isn't actually linear progression, but I don't really wanna do the math.]

That said, 3rd degree burns may be an issue once you slip a case on it that insulates the phone, making it yet hotter, and 2nd degree burns will be more of an issue too. I'd be interested in seeing what the peak temp is during fast charging with a case on, especially one of the thicker cases. If it internally gets to more than 140 degrees Fahrenheit, there's absolutely risk that it could explode, and even if it's not doing it externally, internally it may be nearing those temps.

Or maybe let's not trivialize a defect that can cause 2nd degree burns making them look like nothing?

Chill Maalus, I'm pretty clearly addressing 3rd degree burns, and only even mentioning 2nd degree burns in circumstances that are likely to increase their risk.

What part of this set you off, genuinely? Was it the reference of it as a risk? Was it that I actually looked at the facts? No part of me thinks this is good. This is very obviously and inarguably unacceptable, and no part of my post states otherwise.

Funny too that you ignore the post right next to mine that legitimately is minimizing it.

"chill dude it's clearly addressing the meat being charred and falling off the bone, and only mentioning potentially life threatening blisters in passing".

I mean, I didn't have anything to say with regards to the 2nd degree burns, really, so I didn't feel the need to comment on them. Didn't know any reply I made had to both acknowledge everything I agree with as well as make comment on what I feel was comment-worthy.

So I'll start now. I disagree with your lackadaisical portrayal of me. Neither is it accurate nor does it form a coherent argument against me. It simply acts as an ad hominem used in the place of a substantiated or communicated argument.

I agree with nothing in your non-statement.

Also characterizing 2nd degree burns on the hands as potentially life-threatening was irresponsible of pseudo-me. Pseudo-I shouldn't have done that, as it's untrue. Pseudo-me should know they're severe and serious, but something doesn't need to be described as "potentially life-threatening" to be severe and serious, and in fact, pseudo-me should be aware that this is a minimization of things that don't kill you but severely impact one's quality-of-life, as 2nd degree hand burns would.

Read up what 2nd and 3rd degree burns even are, then we can talk.

I can't say I actually want to talk to someone who takes me in the least favourable light possible, and goes off at me over their own misunderstanding.

Over whose misunderstanding? It was you who doesn't know what second and third degree burns are.

Iphones have fast charging now?

Apparently. I'd drop dead before I buy one myself but a friend told me today that with fast charging the 15 charges to 100% in 55 minutes.

Sooo... still fast charging speeds from over 5 years ago. What have they messed up for it to heat up like that? Lmao

Well naturally this is a brand new technology that Tim Apple invented last week. It's the best in the industry and really, $1000 for a phone this cutting edge is a bargain, even if it can literally burn your hands. /s

Complete opposite. I've never seen any other group of people let their phone drop so low. It's like they do it on purpose. I blame the lack of battery % so they don't get the anxiety effects.

What about 1st degree burns? Would these be ok?

So? My 250€ Motorola also has this feature, they are slacking behind

How long do you figure it'll take them to make a phone that triggers nuclear fusion? Asking for a friend.

This is a massive problem. It's not ok for a device which millions of people use to get so hot. This could cause a fire given the right conditions.

I hope this gets reported on the mainstream news so people realise Apple isn't so great after all.

This is by far not the first time they've had hardware issues with their products. I think hardware is their Achilles heel.

Not that I feel sorry for them considering how much they fleece customers on the prices for the devices, repairs, accessories, the amount of times they tell you to get a whole new Mac when all it needs is 1 part etc.

This could cause a fire given the right conditions.

Something tells me it could also cause a fire given the wrong conditions.

(sorry yeah I'll see myself out)

Apples hardware is one of their strengths. By far the best in class in mosts categories they compete in.

You might want to ask Lou Rossman about that, he would beg to differ.

I remember well when I was an apple fan that the unwritten rule was "never buy gen 1 of apple devices because they will have issues. Always wait for gen 2"

The issues with their laptops, especially the main board, is legendary. Then there's bendgate, antennagate, the cracking of the cases of the white macbooks (which I had) etc

Not a stellar record. Whereas typically we don't see these issues on PC's and Android phones. The only big one was the exploding Samsung Note 7, but Samsung recalled them all and cancelled the phone. Unlike Apple who said "you're holding it wrong" when their antenna design was the real problem.

Many laptop manufactures have terrible hinges, power connectors that break and terrible keyboards. The difference is volume of a single design and media pick up of the issues.

This reminds me of the Samsung Phone incident... not as bad as that but it's just something that popped up in my mind.

Apple is leveling up at each new phone. iPhone are average with a premium price.

Sounds like a really expensive way to keep your coffee warm.

I’m sure this will likely get addressed shortly with a software update. Curious to see if they throttle the CPU / slow charging a bit.

IMHO, this is always the risk you run with day one hardware and software. Early adopters can get burned. In this case both figuratively and literally.

That said, I’ve been hitting some 15 pros pretty hard and I haven’t noticed any heat issues.

But honestly, how does something basic like this pass qc?

As someone in product development, I can attest to some stuff just not showing up until you throw millions of end users at something. You can try your damnedest to simulate real world usage and have all sorts of automated test, but the real world and real users alway find something. You just hope the something is small and patchable.

What a shitty cellphone. That's why I use Motorola phones. They're better than apple, and don't overheat

I had one of those smartphones ages ago and it was awful, one of the updates made it lag so terrible they somewhat fixed that a little in the next few updates! I bet that was intentional to get me to buy a new phone, not a iPhone fan ether tho.

Have they fixed their update policy at long last? Back when I had an X Style it took literally over a year to get the newest version of their nearly stock skin of Android.

If it’s not uncomfortable to hold or triggers the built in heat warning then you are fine. This isn’t a gameboy in the Kuwait sun.

Temps over 35C can cause damage to batteries capacity.

My batteries, who are located in a geographic region with common room temperatures above 35ºC:

Thats nothing.? Sneakily using fahrrneit to make it sound like a big deal. I hate Apple as much as the next guy but this is exploitative journalism

What? 116 degrees is pretty dang hot.

Edit: It's literally at the threshold of a first degree burn.

Its insides getting that hot doesn't matter hell it is more than normal for a phone under heavy load(gaming and stuff)

If you read the article its the entire phone that gets hot, not just the "insides". While a slight increase in temp under heavy load is normal, becoming too hot to even pick up is not.

I mean come on, this is a design flaw without question, you can easily get burned by a 115°F metal case.

Apple themselves say that a phone at consistently higher than 35C will suffer from battery capacity damage

There are at least two countries in the world that use Fahrenheit in a regular basis. US is one of them.

I'll rather they use Celsius, but still it's weird to think this is only to make "exploitative journalism".

Oh no 116f, like seriously guys this will melt the Popsicle in my pocket

That's the treshold for you to get a 1st degree burn. No, it's not instantaneous at that temperature, but it certainly denotes that it shouldn't get there at all.

After several hours of unventilated and insulated continuous unmoving and firm contact… definitely at risk of first degree burns here.

This is just to get clicks.

Apple apologists amaze me. This isn't a fucking cpu inside a shell, it's the outside of a handheld device.

User: "Hey guys my phone gave me a burn, is that normal?"

Apple fanboy: "Depends, what phone is it?"

User: "It's an iPhone"

Apple fanboy: "Oh in that case it's fine, don't worry about it"
