> Pretty similar to the modern threat profile of Android, all things considered I don’t think this is accurate. Not even every nation-state would be expected to have access to iPhone zero days, particularly with the new memory protection rolling out.

I don't think that's accurate, either. NSO Group sold their exploits to several other nation-states, seemingly without much (any...?) vetting concerning the ethics of their government.

I’m not trusting in ethics. I’m trusting in commerce.

MIE should drastically reduce both the production rate and lifetime of zero days. That, in turn, means a focus on maximising profit per vulnerability versus process line.

Whether it's functional after dropping it face down on the glass onto cement/marble is another question! I'm not too concerned with cosmetic scratches. The main issue is the screen shattering. And the back of the phone shattering in older models where the back was glass.

> Whether it's functional after dropping it face down on the glass onto cement/marble is another question

Confirming it is. Source: clumsy as hell.

The glass is sturdier and more scratch resistant than it was ten years ago, when I was smashing an iPhone screen a couple times a year with a case.

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!

I am considering buying the Air over the base model 17. Only concern I have is whether the battery will degrade faster over charging cycles than base model? Someone with more experience in battery tech could explain if that could be the case possibly?

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

Watching that video, the first thought I have is "So much engineering and I still need to buy a phone case with my new phone?" I'm guessing phone cases are still pretty much required if you drop your phone once or twice a month onto cement/asphalt/marble/etc from pocket height. I would be really curious to hear the internal debate at Apple wrt design tradeoffs + durability. E.g. how much of the iPhone design is only…

Cases are great because everyone can get one that matches their risk level and frequency of drops.

Having a sacrificial outer layer that I can replace for $10 is also preferable to letting the $1000 phone take the damage.

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.

Vapor chambers and heat pipes use some of the same physics concepts, but a vapor chamber is significantly more effective for spreading heat across a large area. They’re also harder to manufacture and more complex.

Have you ever seen a CPU or GPU heat sink that has 5-6 heat pipes in parallel because they need to spread the head over a larger area? A vapor chamber is an upgrade over heat pipes in applications that aren’t moving heat from a point to a line.

Don’t be so dismissive. This is actually cool.

Which most people are going to immediately cover with an insulating layer of plastic or silicone. At least the heat will be spread out from one spot (and into the battery?). All phone makers are doing what they can within the design constraints.

> Which most people are going to immediately cover with an insulating layer of plastic or silicone.

Or their hand. Or their pocket.

It’s fine. It’s planned.

The cooling solution’s job is to spread the heat around as much as possible so it can be dissipated in the limited conditions available.

I haven’t used a case in at least a decade. Why do you think it’s necessary?

I have a case, and therefore I don’t crack my screen (or back), ever. When I sell it after upgrading, I can truthfully list it as “like new” (after a battery replacement).

Cases aren’t necessary, have not been for a while. They don’t actually protect your screen.
