Apple has finally turned up to the folding phone party, and it’s called the iPhone Duo. The name is an odd choice for Apple given iPhone Duo is very similar to Microsoft’s own Surface Duo name, a phone Microsoft killed off years ago. Apple had every name in the world to pick from and went with one that already existed. Strange move, but far from the strangest thing about today’s announcement.
Apple confirmed iPhone Duo at its Surprise and Shine event on 9 September, and the full details are in Apple’s own iPhone Duo announcement. We previewed what to expect a few days earlier in our iPhone 18 Pro launch preview. It’s Apple’s first folding phone, built in a book style passport design rather than the tall, side by side fold Samsung and HONOR have favoured for years. Closed, you get a 5.4 inch outer display. Open it up and you’re looking at a 7.6 inch inner screen, which Apple says makes it the thinnest iPhone ever when unfolded. It runs the same A20 Pro chip as the iPhone 18 Pro, comes in star white or night sky, and starts at €2,369 in Ireland for 256GB. Pre-orders open Friday 16 October, with the phone landing Friday 23 October.
Here’s my take after watching the whole thing land. That passport shape is the right call, and I think Apple might have just designed the best folding phone on the market. Unpopular opinion time.
- Why the passport shape wins over the tall fold
- That camera bump, and what you're paying for
- Does iPhone Duo have MagSafe?
- iPhone Duo is eSIM only everywhere, not just the US
- No Face ID, and no third camera lens
- Why Apple's single platform beats Android's fragmented folding market
- Right, that's the rant done. Back to the phone itself.
Why the passport shape wins over the tall fold
I’ve spent close to a year in and out of folding phones, including HONOR’s Magic V5, and the tall, side by side fold makes sense for one thing and one thing only, which is productivity. Two apps stacked on top of each other, or side by side once you turn it landscape, genuinely works well for getting things done. What it doesn’t do well is video. Watching anything on that tall aspect ratio means huge black bars, and it never feels like the phone was built with content in mind.
iPhone Duo’s passport style folds out into something wider and more landscape friendly, which is exactly the shape you want for watching something back or gaming. Whether Apple wants to admit it or not, this is the format the rest of the folding phone market has been quietly drifting toward anyway, and I think it’s the right one for the average buyer. The tall fold is a productivity tool wearing a phone costume. This is closer to an actual phone that happens to fold. I totally never thought of the portrait mode – seems so obvious now when I see it.
That camera bump, and what you’re paying for
Watching the livestream, the camera bump on iPhone Duo is hard to ignore, and it reminded me a lot of the bump on HONOR’s own folding phone. Being the thinnest iPhone ever is a genuinely impressive engineering claim, but it doesn’t erase a lump on the back that’s going to catch on every table you set it down on. Apple even straight up admits they stuffed a load of tech into that bump.
It’s also worth being clear on what you’re getting for the money. iPhone Duo runs a 48MP dual camera system, a main lens and an ultra wide, with a 2x optical quality zoom built into the main sensor. There’s no third telephoto lens like you get on the iPhone 18 Pro. You’re paying flagship money, arguably more than flagship money, for a camera system that’s a rung below Apple’s actual flagship. This is a content consumption phone, more than content creation.
Does iPhone Duo have MagSafe?
Yes. iPhone Duo supports MagSafe wireless charging, and Apple’s own iPhone Duo FAQ confirms it reaches 50 percent in around 20 minutes on a wired charger, or 50 percent in about 30 minutes wirelessly with a MagSafe or Qi2 charger. I’ll admit I went into today confused on this one. Given how thin the phone is, I assumed MagSafe’s magnetic ring simply couldn’t fit, and Apple didn’t make a big deal of it on stage either. Turns out it’s in there, which is a relief for anyone with a shelf full of MagSafe accessories.
iPhone Duo is eSIM only everywhere, not just the US
Apple has sold eSIM only iPhones in the US since the iPhone 14, but iPhone Duo is the first Apple device to go eSIM only worldwide, with no physical SIM tray anywhere it launches. That’s the beginning of the end for the physical SIM card, at least as far as Apple’s concerned.
This means network choice is limited in Ireland with only Gomo, Lyca Mobile, Virgin Media and Sky Mobile supporting eSIM from the best of the monthly SIM-only deals, so most people switching to iPhone Duo won’t notice much difference beyond a QR code instead of a tray. The one group who might care are customers on 48, the budget network riding on Three’s infrastructure, which doesn’t currently support eSIM at all. If that’s you, it’s worth checking with your provider before you commit to a phone this expensive. But then agian if you can afford the iPhone 18 Duo…
No Face ID, and no third camera lens
Two more things worth flagging while we’re being honest about trade-offs. There’s no Face ID on iPhone Duo. Apple has built Touch ID into the side button instead, which handles unlocking whether the phone is open or closed. And as above, you’re getting two rear cameras rather than the triple lens setup on the iPhone 18 Pro. Neither is a dealbreaker on its own, but stacked together they’re a reminder that iPhone Duo isn’t simply an iPhone 18 Pro that folds.
Why Apple’s single platform beats Android’s fragmented folding market
Here’s the bit I think gets missed in most folding phone coverage. When Samsung, HONOR, Motorola and Xiaomi bring a folding phone to market, developers building for it are designing around a fractured Android landscape, with different screen ratios, different hinge behaviours and different software layers depending on the manufacturer. When Apple launches a folding iPhone, developers are building for one company’s hardware and one version of iOS, shipping to a single, enormous audience on day one.
That’s unavoidable, and it’s why I’d bet on iPhone Duo getting better designed apps and a more consistent experience than any Android foldable, purely because there’s one target to hit instead of a dozen. It’s not that Apple’s engineers are smarter. It’s that a single, tightly controlled platform is simply an easier one to build well for.
Right, that’s the rant done. Back to the phone itself.
I’ve watched folding phones for years on this site, back to our original take on whether anyone even wanted foldable phones, and I’ve gone from sceptic to genuinely impressed by what a good one can do. Apple turning up years after Samsung means it’s had the luxury of watching everyone else’s mistakes before making its own. On the strength of that passport design alone, I think it’s used that time well. Whether it was worth the wait at this price is a different question entirely, and one only your bank balance can answer.
iPhone Duo is available to pre-order from Friday 16 October, on sale from Friday 23 October, with US pricing starting at €2,369 for 256GB in Ireland.
