I have an iPhone Air now and have no complaints about the heating. The thinness is worth the occasional heat and throttle down. Every time I pick up this phone, it just feels fantastic!

Serious question: how is the thinness providing value? Is it simply the feel?

Back when I had the iPhone 5S (7.6 mm vs the 5.6 mm of the iPhone 17 Air): It provided value in terms of feel. It felt like a piece of art meeting cutting edge technology. It wasn't about showing off.

It was also so light that it felt safe to use it without a protective case. And not that expensive.

This is a heat pipe. A technology from the 60s. Your laptop almost certainly has heat pipes in it. They usually use alcohol rather than water as the phase change material though. The (relatively) novel thing is that it's packaged small enough to be in a phone. I suspect the only reason it hasn't been used in handhelds more is because the TDP of mobile processors wasn't high enough to warrant it.

As I understand it, it’s more than that: there are small “inverted pyramids” that cause the water to condense more rapidly, to extract even more heat from the system.

Can this tech be used for EV batteries?

I guess? But vapor chambers are mostly good where space is a premium and where passive (non-powered) cooling is enough. I'm guessing for EV batteries, better options exist since you obviously have power. Although sometimes vapor chambers are used in conjunction with active cooling.

Heat pumps are way better if you have to manage a lot of heat anyway.

Not exactly brand new tech, but now on a mobile device without the long-term security baggage that often comes from using Android.

I think NSO Group has pretty thoroughly demonstrated that iOS users aren't exonerated from security concerns.

Yes, state actors will be able to breach into your iOS device if you're deemed important enough.

Edit: Meanwhile your average Android device has multiple publicly known remote execution issues.

Yup. Pretty similar to the modern threat profile of Android, all things considered.

> your average Android device has multiple publicly known remote execution issues.

Help me distinguish between "publicly known" RCE vulns and private ones. Do the privately owned exploits like FORCEDENTRY count as "publicly known", or only the Greykey/Cellebrite exploits used by governments?

I find that I treat it very gingerly. Something in my mind expects it to be fragile; presumably because it's thin and looks like glass.

Last night I encountered a 3 min+ ad on YT about the construction of the iPhone 17 Pro. A few seconds were devoted to the cooling system. I watched the whole thing. It was better than the video it interrupted. https://youtu.be/_-AS5DtDeqs?si=rTfubRDArVupqREt

This might be the first time I’ve seen someone happy about an advertisement in the wild. It is a cool video though!

Heat pipes are one dimensional (a pipe), vapor chambers are two dimensional (a square chamber). Most vapor chambers I've seen on GPUs have the chamber attached to lots of small heat pipes on the side though (they even note this in article, in case you feel like reading it).

That said, I assume the main technical breakthrough here is in manufacturing, producing tiny chambers consistently in enough volume for iphones.
