The iPhone Duo is the first iPhone that folds, and pre-orders opened in October 2026. It is also the most expensive iPhone Apple has made. Here are seven facts to get straight before you spend anything.
Updated October 2026. This story is moving quickly, so check the official pages linked at the end before you rely on any detail here.
1. It has two screens
That is the whole idea. There is a smaller screen on the outside, about 5.4 inches, for quick things like checking a message. Open it up and there is a larger 7.6 inch screen inside, closer to a small tablet.
So it is a phone when shut and something bigger when open. You are paying for that second screen and the hinge that makes it possible.
2. What it costs
The iPhone Duo starts at $1,999 for the 256GB version. Storage pushes it up quickly:
- 256GB: $1,999
- 512GB: $2,199
- 1TB: $2,599
- 2TB: $3,199
Apple also lists monthly payment plans from about $83 a month over 24 months. Spreading a cost does not reduce it, so look at the total before deciding.
3. The dates
Apple announced the phone on 9 September 2026. Pre-orders opened on 16 October, at 5am Pacific time, through the Apple website and the Apple Store app.
The official launch day is 23 October in more than 70 countries, with another 28 markets following on 30 October.
4. Demand is high, so delivery dates may slip
Coverage after pre-orders opened reported that stock sold out quickly and that delivery estimates moved a long way back for later orders. Reports differed on exactly how far, which is normal in the first hours.
The practical point stands either way. If a specific date matters to you, check the date Apple shows you at checkout rather than the launch date in a headline.
5. The parts worth checking yourself
Folding phones are new for Apple, and a few things are worth your own eyes rather than a spec list:
- The crease. Every folding screen has one where it bends. How visible it is varies.
- Weight and thickness. Two screens and a hinge add both. A folding phone usually feels chunkier in a pocket.
- Durability. A hinge is a moving part, and moving parts wear. Check what the warranty covers.
- Cases. Accessories for a brand new shape take time to appear.
6. Reasons to wait
There is a decent argument for not buying the first version of anything. First generation hardware tends to be the heaviest and the most expensive, and the second version usually fixes the obvious complaints.
If your current phone works, waiting costs you nothing. Our guides on when to upgrade your phone and how to read phone rumours go through how to make that call without the marketing.
7. Moving your stuff across
If you do buy one, the move is the easy part these days. Apple transfers your data during setup from a backup or directly from your old phone. Back up first anyway, because a backup you did not need is better than one you did not make. Our guide to backing up your iPhone covers it in order.
Who the iPhone Duo is actually for
Folding phones suit some people and are a waste of money for others. Be honest about which group you are in before spending two thousand dollars.
It makes sense if you read a lot on your phone, watch a lot of video, or carry a small tablet as well as a phone. In that last case the big screen replaces something you were already carrying, so the price is easier to justify.
It makes less sense if you mostly message, scroll and take photos. Everything you do fits on a normal screen, and you would be paying for a hinge you rarely open. A standard iPhone does those jobs just as well and costs far less. If you are weighing it against a regular model, our comparison of the iPhone 18 Pro and iPhone 17 Pro is a useful reality check on what you gain.
How to look after a folding screen
The inner screen is plastic rather than glass, because glass that thin would shatter when folded. Plastic scratches more easily, so a few habits help:
- Do not use a screen protector unless Apple says it is safe for the folding display.
- Keep sand and grit away from the hinge. Grit in a hinge is what actually kills folding phones.
- Do not force it shut on anything, not even a thin card.
- Press the inner screen with a finger, not a fingernail.
None of that is difficult. It is just a different set of habits from a slab of glass you can throw in a bag.
What to check before you commit
Before you confirm an order, three quick checks save a lot of annoyance later.
- The delivery date shown at your own checkout, not the launch date in a headline.
- The return window, so you know how long you have to change your mind.
- Whether your current case, charger and accessories carry over, because a new shape usually means buying new everything.
If you can, handle one in a shop before buying. A folding phone is one of the few devices where the feel in your hand genuinely decides whether you will enjoy it.
And if you decide to skip this one, nothing is lost. Folding phones are not going away, prices usually fall, and the second version of any new design is normally the better buy. There is no prize for being first, and plenty of people who waited a year ended up paying less for a better phone.
Common questions
How much is the iPhone Duo? It starts at $1,999 for 256GB, rising to $3,199 for 2TB.
When does it come out? Pre-orders opened 16 October 2026 and launch day is 23 October in over 70 countries, with 28 more on 30 October.
How big are the screens? About 5.4 inches on the outside and 7.6 inches on the inside when opened.
Will I get it on launch day? Only if you ordered early. Reports said stock sold out quickly and delivery dates moved back, so trust the date Apple shows at checkout.
Should I buy the first folding iPhone? If your phone still works, waiting is reasonable. First generation hardware is usually heaviest and dearest, and version two normally improves it.
