Nearly 10 years in to foldables, and they still bring so many caveats. They are consistently worse for size, weight, shape, cameras, battery, robustness, and longevity. I don't think I'd ever recommend one.

On the other hand, the advantages are... an iPad like experience sometimes? Or a smaller phone for the flip form factor? The flip form factor certainly does not pay off. I'm honestly not sure who the trade-offs pay off for.

18-20 million foldable phones were sold in 2025. About 10 million PS5 consoles were sold in that same period. So there's definitely a bit of interest.

Why does it have to be an all-or-nothing fight for the final smartphone form? Can't it just be a semi-niche product that some people buy?

▲danpalmer 2 hours ago | parent | next [-]

I don't think this is a fair comparison, they are different markets – most people need a smartphone today, nobody really needs a PS5. A better comparison is to say that of smartphones sold in 2025 (~1.65bn), foldables represented ~1%. That's pretty niche.

▲CharlesW an hour ago | parent [-]

That’s pre-Apple’s entry into the market, which will triple the size of the foldables market in the next 12-18 months. And cnsidering how bad foldables have been and how much better they’ll get, that’s surely not the ceiling.

▲danpalmer 2 minutes ago | parent [-]

Apple sold ~250m of those ~1.65bn, so if you work on it being Android only, then foldables are ~1.4% instead of ~1.1%.

For the foldable market to triple in size, Apple would need to sell 40m this year, which if we assume a flat year for overall numbers (likely given rising costs this cycle and the trend of flattening sales anyway), then it would mean the fold taking 16% of all iPhone sales. For a ~2000-3500 USD phone (base model, international pricing), that's not happening.

Why would you think foldables are about to get a lot better? They have improved over the last 10 years, but the original caveats are pretty much all still there, and the iPhone Duo doesn't appear to improve on any of them in any meaningful way.

> Can't it just be a semi-niche product that some people buy?

As a fan of smaller smartphones (the likes of which aren’t made anymore), I thought the answer to this was supposedly a resounding no.

I mean, Apple sold millions of iPhones mini but we were told that wasn’t a viable product.

Some countries, like China, LOVE foldable phones. It’s fun to see how cultural it is.

▲Gigachad 2 hours ago | parent [-]

From what I've gathered, China is much more in to mobile gaming and livestreaming than the rest of the world. Folding phones seem to appeal to those who primarily consume media on their phones, so it checks out they would want larger phones.

I suspect this might be my blindspot. I use my phone a huge amount, but almost never for watching video or gaming. Being able to have a "full screen" video, and another app running "full screen", with the effectively 2x screen space, makes sense.

▲bilalq an hour ago | parent | prev | next [-]

I love my Pixel 10 Fold and can't imagine ever going back to a non-foldable now. The larger screen is great for productivity. Reviewing PRs on the larger screen is way more comfortable than a normal phone size. The built-in terminal app also works nicely with herdr and Tailscale to let me connect to my work machine. I can interact with my agents and get real work done on the go. I also have saved split views so I can quickly launch two apps side-by-side. I do mobile app development, so being able to have the app I'm developing open side by side with Slack or Linear to create issues or discuss with people is very convenient.

I don't know if terminal access is as easy on iPhones, but the utility is there for many work related use-cases. I do think the more square-like form factor of the Pixel to be better for productivity than the rectangular form of the Duo, but the latter is nicer for videos.

▲apparent 32 minutes ago | parent | next [-]

> The larger screen is great for productivity.

Interesting, reviewers (Joanna Stern) said that it was not great for productivity, more for consumption. Perhaps it works for your kind of tasks, but not hers/others.

▲dansquizsoft an hour ago | parent | prev [-]

Yeah don't listen to the original commenter, I absolutely love my foldable too.

▲rozal 6 minutes ago | parent | prev | next [-]

you are severely underestimating the value of a pocketable ipad. this comment isn’t the type that age well

▲SenHeng 39 minutes ago | parent | prev | next [-]

My iPad mini gets multiple times more use than my iPhone, there have even been times where I’ve left my iPhone by the bedside table for days.

It’s mainly a consumption device, I got it initially for reading ebooks while on the train. It’s also a surprisingly good workhorse by itself, or as a second screen for a MacBook. I even make phone calls with it (via the iPhone) simply because it’s always in or near my hands.

So the Duo certainly piqued my interest when it was announced, until I learnt it doesn’t do iPad-y stuff like universal control or sidecar. I’ll wait for the next gen.

▲D13Fd 13 minutes ago | parent [-]

It felt wrong to me when they split iOS in two to make the iPad OS, and now it feels super wrong.

The whole selling point of this is that it’s an iPad mini in your pocket, IMO. It’s really a shame they couldn’t give it all of the iPad’s best features.

▲jayd16 an hour ago | parent | prev | next [-]

Phones have gotten bigger and bigger and yet you can't fathom folks want a big screen?

▲asah 2 hours ago | parent | prev | next [-]

??? everyone I know who's gone fold hasn't gone back.

yes, battery & camera are a generation back and water/dustproof is even worse.

but productivity and fun are off the charts: slab phones feel pathetic once you've got a fold. Communication apps show you the list of conversations as well as the current one - or the current one and the details/multimedia. Google Maps shows the map and the listing details/reviews. Games and multimedia are delightful. Photos are full sized, and you can see what you're shooting in detail - if you shoot with a digital camera, remote shooting is amazing because there's enough space to show detailed focus.

Not to start an endless device debate but a good chunk of these use cases make more sense to do on an iPad or to just have a separate device in general.

I know, I know, that’s not as portable, that’s not a device you have with you all the time like a phone.

But we’ve seen pretty mixed results on the “combine devices into one” playbook. Sometimes it’s a huge hit, sometimes not so much.

A foldable phone + split keyboards = a mini laptop fit inside your pouch

▲Grombobulous an hour ago | parent [-]

Well, besides the software, which is very much not laptop-like.

I think the main thing is that for this kind of money you have a lot of options. You could even buy a GPD device that is an actual full blown pouch sized laptop and buy a regular iPhone for the same price.

> I think the main thing is that for this kind of money you have a lot of options. You could even buy a GPD device that is an actual full blown pouch sized laptop and buy a regular iPhone for the same price.

I have done this! I currently carry a GPD Win Max 2 around, but let me be clear about some elements of this: the keyboard on a sub-device is just as important as any other, and the keyboard on GPD devices is not great. A sub-device has to be maintained and charged and given love and care just the same as any other device. The amount of times I have found my cute linux laptop dead when I wanted it, outdated, or randomly signed out of services is quite high (and this is with an onboard LTE modem). Carrying around a folding (or even non-folding, like a Magic Keyboard) is lighter than a sub-device, will last significantly longer in terms of charge/battery, and does not require any of the secondary device maintenance that is needed with one normally.

To me a folding phone is an absolute no-brainer in terms of why it is useful. You can get a very, very good keyboard for cheap, or try many, and completely eliminate the need to carry a second device.

Another huge use case I have is transit/travel video playback. I do not normally want to bring an iPad or even a secondary laptop during travel, so this effectively deletes one more device that I have to charge, update, bring adapters for, etc. It is effectively all of the benefit of having a tablet at all times, a sub-laptop at all times, and requires absolutely no additional charging or maintenance.

▲wahnfrieden 2 hours ago | parent | prev | next [-]

Huge screen that's pocketable and also your primary device (not a 2nd device you need to choose to carry in addition to your phone, and have a bag for) and ability to have 2 apps at once on iOS is in fact highly valuable for many.

▲thewhitetulip 2 hours ago | parent | prev [-]

For flip phones the payoff is that its small.

We've been asking for a small phone for so long now

And then now we have one. But its too costly. I'm waiting for the cost to come down

For foldable phones the factor is that you have a phone and a small tab all in one.

▲danpalmer 2 hours ago | parent [-]

I had a flip phone and I got it for this reason, but it honestly just sucked. The outer screens are too small to be useful, or in the case of Samsung, just don't have the right feature set to be useful. That means the phone ends up just being a full size smartphone with more steps to be able to use it.

▲Grombobulous an hour ago | parent | next [-]

They’re good for women’s jeans.

It’s not about the steps to be able to use it, it’s about fitting in your pocket.

Everyone I have ever met with the new Motorola Razr product lineup owns that phone so it fits in women’s jeans pockets.

Samsung, lol

Spending thousands of dollars on hardware I don't own is not for me, but foldable touchscreen phones are, objectively, pretty freaking cool pieces of engineering work. Very cool breakdown of the hardware.

Maybe 2027 will be the year of the Linux desktop (thanks to AI), but meanwhile, I 'll just pay the $100/yr Apple tax to run my code on my device, and get on with my life.

ive been really enjoying my iPhone duo so far, its hard to imagine going back to a normal phone. it makes it so much more fun to schedule appointments, read blog posts, vibe code, update my calendar before a trip, watch movies, etc...

▲tim-projects 2 hours ago | parent [-]

I have the same experience with 2 phones. Can't imagine having one phone anymore. No risk of screen damage either..

I wish they'd go back to text and images for the teardowns.

I, too, preferred the internet when it was just text!

▲benbojangles 2 hours ago | parent | prev | next [-]

I noticed a race among social media to teardown or literally tear down the iphone duo this time. Bendgate is always a classic one to do for views, scratchgate is another one content makers love as they can wear an expensive watch while they carve shapes into their expensive purchase while poor people from around the world clutch pearls. The folding design is a great opportunity for content makers to target for views, but my question is why the content makers never invent something, design it, market it, pay large amounts for iso safety testing certification, then make teardown content on what they created a la banksy love is in the bin

▲AlotOfReading an hour ago | parent [-]

I'm sure the 5T multinational corporation is glad you're defending it against the small-time content creators bullying it, but you might notice that the people behind this teardown do in fact sell products they've designed. So do other popular creators in the teardown category like jerryrigeverything.

They can't do teardowns of their own products though. Anything interesting they'd find in a teardown should have been caught at the design stage, and they're hardly unbiased about their own products. At most they can do design decision videos, which many do. For opinionated testing they'll send their products to another creator instead.

▲benbojangles an hour ago | parent | next [-]

Why does it matter if its 5 or 5T? The teardown or tear down is what is important. I invented something a few years ago in my backyard workshop while on welfare and it got tore down which made me realise something odd is going on

▲Domenic_S 17 minutes ago | parent | prev [-]

nah they're right, legit teardowns with microscopes & CTs & chip identification are interesting; most 'teardowns' are little more than destruction porn. jerryrig at least gives some info (scratch test) but even he quickly devolves into uninteresting destruction.

It's nothing new - is will it blend still a thing? - but man it seems like they're everywhere now
