Apple may reduce the performance of the 3nm A17 Pro processor due to massive overheating of the iPhone 15 Pro::The problem of overheating of iPhone 15 Pro and Pro Max smartphones is becoming widespread. It is possible that Apple will be forced to take the unpopular step of reducing the performance of the latest 3nm A17 Pro chip.

How does something like this not show up in tests?

[-] whitecapstromgard@sh.itjust.works 68 points 11 months ago

It does.

Usually engineering and R&D sees these things, but they are too scared to contradict ambitious timelines set up by management.

[-] DoomBot5@lemmy.world 40 points 11 months ago

Or they report it to their managers, and those managers are too afraid to report it up the chain to contradict an ambitious timeline.

Or marketing. I've heard innuendo that at Apple, marketing has vetoes

[-] yoo@lemmy.world 26 points 11 months ago

They just figured oh well it works well in Cupertino. They omitted the fact that Cupertino doesn’t get super hot, ever.

[-] dth@lemmy.world 14 points 11 months ago

oof i can’t imagine using it in my country where it’s 30 degrees celcius and above on average everyday.

[-] ilmagico@lemmy.world 4 points 11 months ago* (last edited 11 months ago)

oof i can’t imagine using it in ~~my country~~Apple's home state, California where it’s ~~30~~ 40+ degrees celcius and above on average ~~everyday~~ in summer, and Death Valley has pretty much the world record.

I mean if they didn't test it in Cali I wouldn't know where at all...

I haven’t noticed a heating issue and I live in a very hot climate. So, it’s not universal.

[-] iMike@lemmy.world 4 points 11 months ago

My 15 pro max is cold all the time, I haven’t played any 3d games yet though. It was cold during restore process and it’s cold when charging

[-] kobra@lemm.ee 3 points 11 months ago

Yeah I’ve not had problems on any of my families 15 or 15 Pros, however my iPad Air 5 got hot af last night installing iOS 17 and I ended up putting it in a stand and pointing a fan at it lol

[-] MassRedundancy@sopuli.xyz 3 points 11 months ago

Same here, no issues so far.

[-] gravitas_deficiency@sh.itjust.works 7 points 11 months ago

People have used it in very hot areas and it has been fine, with no overheating issues.

People have used it in very temperate areas and it has turned into a small furnace.

The controlling variable is almost certainly not ambient temperature.

[-] systemglitch@lemmy.world 19 points 11 months ago

Oh they knew. Apple is just pure scum.

[-] Contend6248@feddit.de 14 points 11 months ago* (last edited 11 months ago)

I can assure you it did, they just hoped no one would notice

[-] Haha@lemmy.world 13 points 11 months ago

Seems they don’t test

[-] stonedemoman@lemmy.world 12 points 11 months ago

I could see a case made for the test units having much better heat transfer and once mass produced the silicon lottery inevitably made some chips run hotter. But those variances are not massive, so it would've already had to run pretty hot. IDK

[-] stealth_cookies@lemmy.ca 6 points 11 months ago

When developing a product you order "process corner" chips that are primarily used for testing the memory timings (through a process called Shmoo) to make sure it is stable. The "FF" class of these chips are also useful for testing thermals as they draw the maximum power you will see with the silicon lottery. So assuming Apple did this properly they should have had a good idea of what the product temperature is at the operating temperature extremes.

[-] stonedemoman@lemmy.world 2 points 11 months ago

Interesting, so SOP would rule that out too. I didn't know this.

Now the 20% performance increase from last years becomes 10 and you have basically the same phone as last year. Good job to ensure people preorder.

[-] johnthedoe@lemmy.ml 3 points 11 months ago

Why put the pressure on even selling it as a new product. Should’ve just pulled a 14s. Exact same but with usbc and made bank for another year.

Mere speculation with no sources. Or Apple could do nothing.

[-] CandyPants@lemmy.ml 11 points 11 months ago

I'm not an Apple fan by any by any means, but what a junk article! "Apple may reduce the clock speed of the processor"? C'mon! They do plenty of shitty things to dislike them for already. We don't need to reach for hypotheticals...

I think it speaks volumes for how stagnant phone innovation has become when their marketing campaign is centered on the metal the frame is made out of.

[-] ALilOff@lemmy.world 2 points 11 months ago

If this turns back into being Samsung Galaxy bombs…it’s going to be looking a lot worse if they do nothing.

[-] Lemmylaugh@lemmy.ml 33 points 11 months ago

Ming-Chi Kuo believes that the problem can only be solved by artificially limiting the performance of the A17 Pro chip. However, this is unlikely to have a positive impact on sales of new smartphones. Alternatively, Apple can ignore the problem, but that won't make the iPhone 15 Pro and iPhone 15 Pro Max more popular either.

This whole article is based on just one persons opinion.

[-] eee@lemm.ee 12 points 11 months ago

this is also a guy who knows a lot about, and has been following Apple news for a long time.

[-] HollandJim@lemmy.world 21 points 11 months ago

He’s also been wrong a lot and we don’t need to constantly consume everything he says as fact.

[-] DietBajaBlast@lemmy.world 3 points 11 months ago

The company further told Forbes that the fix, which should come with iOS 17.1, won’t result in throttled performance, which some, like Apple supply chain analyst Ming-Chi Kuo, have said was a possibility.

At what point do we add active cooling to phones?

I don't mean that as a joke, there are some really interesting systems being developed (which are functional) that are extremely tiny that can move air with no moving parts, they're being developed for exactly this sort of use in electronics.

So, no need for a fan that wears down, creates noise, etc.

The biggest issue would be keeping the air channel free of dust and debris, if they can figure that out, then adding a few millimetres of thickness and a small weight increase in order to accommodate future higher capability processors seems entirely acceptable.

Come to think of it, who's to say the air needs to come from outside the phone? You could have a closed system, with air channels moving throughout the phone's metal chassis, acting a little like a heat pump, to better distribute the heat generated in one spot across the entire phone surface area for dissipation.

Phones already use their chassis for cooling, this would just significantly increase the efficiency with no exterior changes. Hmm....

[-] Acters@lemmy.world 9 points 11 months ago* (last edited 11 months ago)

This sounds promising. Dustproof. I dont think waterproofing the air channel will be necessary. This can be used as a way to create a channel for air to pass through without compromising the waterproof seal for the phone internals. The air channel can be a pass through and offers a big benefit in cooling. If there is blockage or damaged fins(I think they are vibrating fins.), then the phone will get warm and automatically throttle. A repair will not be needed unless you want the full performance. I live in the hot desert, and active cooling would be a dream come true. Every high-end phone gets hot to the touch from using GPS or streaming outside.

Edit: Another note is that most people don't beat up their phones with high-pressure water(dirty or clean). If that was the case, then the phones water seal would suffer or be compromised as they are water resistant to low pressure and may not seal against high pressure.

Thin and flat too!

[-] ilmagico@lemmy.world 2 points 11 months ago

move air with no moving parts

That would be a passive cooling system.

[-] Car@lemmy.dbzer0.com 13 points 11 months ago

No? Passive systems don’t do anything to cool other than simply exist.

These systems use energy and are deliberately activated to influence how heat is transferred. That’s the difference of active vs passive.

Bizarrely I’ve had zero issues with overheating on the 15 Pro Max, even when playing games while charging or during initial installation. Does anyone know other scenarios in which it overheats?

[-] mriguy@lemmy.world 10 points 11 months ago

Same here. My 15 pro max never gets noticeably warmer than my 14 pro did, even during the initial setup, where it’s doing lots of things. It seems more likely that this is a manufacturing problem that only affects some phones, because people are reporting super hot phones, most of the time, which nobody I know has seen. The phone itself is generating the heat - the climate difference doesn’t sound like the cause.

[-] dth@lemmy.world 6 points 11 months ago

i guess when you live in a tropical country? like by default the weather is super hot so naturally phones tend to overheat easily too.

[-] kratoz29@lemm.ee 2 points 11 months ago

That is a valid opinion, that has happened to me with all my devices, Android and iOS.

[-] gravitas_deficiency@sh.itjust.works 6 points 11 months ago* (last edited 11 months ago)

It’s not ambient temperature. Tons of people have had no problems using it in in places like Arizona or Florida. Other people have had it turn into a small furnace in much cooler areas / indoors. There’s something else going on.

[-] outplayed@lemmy.world 4 points 11 months ago

Apparently it can heat up randomly while doing something not intensive like listening to music or even sitting in your pocket, according to two people from the WVFRM podcast

[-] iMike@lemmy.world 2 points 11 months ago

Same here, my 15 pro max is cold all the time

[-] iHUNTcriminals@lemm.ee 2 points 11 months ago

Did anyone stop to think that maybe the reason you are hearing about so many people experiencing overheating on the iPhone, is because the far larger group of people that aren’t experiencing overheating have no reason to post?
