You want a 96GB RAM phone and only plan to keep it 3 years? I cannot fathom the way some of you live. I have an iPhone SE from 2022 that I don’t expect to get rid of before at least 2-3 more years, meaning it would have been in use for 6-7y at minimum. And it’s perfectly comfortable to use, I’m not forcing myself in any way to keep it longer. And you’re talking about wanting a ridiculously expensive phone and only ha…

I couldn’t agree more. I’m typing this on an iPhone 12, bought new 6 years ago. My phone still feels snappy. And it gets me through a whole day with 60%+ battery remaining. The only real complaint I have is that I only have the 64gb model. I need to delete things every time a software update comes out because of how bloated modern software has become. But the hardware is fantastic. I have no idea how much ram my phon…

You're missing the important bit in the GP comment:

> the most important property of compute devices right now

Memory didn't matter when iPhone 12 was released, but these days it determines which local LLMs you can run on device. That's the point of that comment.

... don't make it so shallow then. Perfectly possible in a consumer-friendly 3D printer for a face or even human body if you have lots of time for the prints.

but what are we really trying to solve here. you're suggesting a helluvalota work for what purpose?

My contention is every 5 years release a mini spec with hardware bumps. Everyone jumps in and everyone upgrade. It only has the larger size space spec. Rinse and repeat. If you have a "known" or "expected" cycle, people can rely on that.

This has been my hope. Relase one, say "oops no market", and then come back several years later

Me too, still surviving on 12 mini. Issue a new mini and you’ll have my money the minute that the shop opens.

And here we are back to the crux. Sure would be nice if the released material was verifiable instead of "trust me shitstick"

Why? What do you do on your phone that makes you care about memory bandwidth?

in 2026? LLM performance, for one.

The things we need to know most, RAM and Memory Bandwidth, are unfortunately missing from the release. Their absence doesn't bode well.

What do you do with your phone that requires you to know the memory details? Genuine question, I have absolutely no idea how much memory my iPad or phone have and don’t see why I would need to know

Ok Bill.

Looking forward to the photo samples with the variable aperture. If it's something you can manually set (with the Camera app or third party), that would be neat. The miniaturization of this mechanical piece is really quite wild. Eh, that's maybe about it.

While it is a cool technical advance to see, its use case is probably niche. One of the biggest things people say about photography is lighting. In general, if you can get more photons onto your imaging plane, you will have a better picture. This is why phone cameras, despite advertising 100s of MPs, still fall short. For the same field of view and capture conditions, fewer photons are collected because phone sensor…

The iPhone 18 Pro main camera is f/1.48, which is half a stop wider than the f/1.78 main camera on the 17 Pro. An f/1.48 fixed aperture would probably not be ideal (less depth of field, more revealing of lens aberrations) so there is a real light gathering advantage to the variable aperture.

>Also a phone already starts with very deep depth of field

Fairly deep. You can easily see background blur on a modern iPhone camera if you focus on something close. The very fact that the cameras all have variable focus shows that depth of field isn't as deep as all that. The extra depth of field from a narrower aperture could certainly be useful in some cases, such as landscapes. Here's a question for your favorite LLM:

"If I am shooting an iPhone 17 Pro main camera, what aperture would I theoretically need to get perfect focus from 1.5 meters to infinity, assuming a CoC suitable for a 12MP shot?"

Answer: about f3.2 if you manage to focus at the optimum hyperfocal distance.

>which when stopped down physically reduces the amount of light from the scene that reaches the sensor

As you say, this is only the case if you can't increase the exposure time to compensate. In daylight you will often have plenty of latitude to do so, even without image stabilization. Typical daylight shutter speeds at f/1.78 can be around 1/1000 at base ISO, so there is plenty of room to increase exposure time by 2-3 stops in those conditions.

The credibility comes from who took the photo. The next logical and easy step is for this metadata to flow to the user agent. I'll know that it was taken by a legit journalist photographer. And id not, I can have my user agent make it fuzzy or replaced with a kitten photo.

I think this is where we are headed. This feature seems useless on it's own since someone will eventually find a way to extract the key from the iphone and sign any image. But if they could make it so every iphone uses it's own key and the photos show "Taken by xyz" and it's linked to their icloud or identity somehow. That way images shared around will still be able to be linked to a source that you can choose to tru…

I don't think we'll treat them as fake but they would probably undergo more scrutiny - perhaps in a crowd-sourced manner that provides an overall score of probable legitimacy.

If that became popular, the AIs would learn how to generate a realistic depth map along with any generated image.

The photos are cryptographically signed in the apple image pipeline so it's not as simple as just AI generating something. That said, I can't see how this is any different to all the other times we have embedded crypto keys in consumer hardware where eventually someone finds a way to extract the key and the whole thing is busted open.

Given the whole private cloud bit, I am assuming they keep the private keys server side and never let them out.

I love that it has a feature to prove images came from the real world: > Users can now prove the authenticity of a photo taken on iPhone 18 Pro models with Apple Reference Image, powered by the new sensor in the Main camera that can sign every pixel it sees. When a photo is taken in the new Reference mode, the camera captures signed sensor data that Private Cloud Compute develops into an unalterable reference image.5…

A mobile phone.. an internet communicator.. a music player.. don't you get it? well, steve, actually 18 years later it's a .. camera
