iPhone Duo Goes on Sale at $1,999 as Supply Runs Short: What Buyers Should Know

Apple's first foldable phone, the iPhone Duo, went on sale around the world on Friday, October 23, starting at $1,999 for 256GB and climbing to $3,199 for a 2TB model. Supply is so tight that new online orders were already being quoted delivery dates in late January within minutes of pre-orders opening a week earlier.

That makes launch day less about buying a phone and more about finding one. Apple told shoppers that stores would hold only limited walk-in stock in the US, UK, Canada and Australia, and it expects that stock to sell out quickly.

The stakes are high for Apple. The iPhone line generates roughly half of the company's revenue, and the Duo is the biggest design change in the phone's nearly two-decade history, Bloomberg reported.

Key facts at a glance

• Price: $1,999 (256GB), $2,199 (512GB), $2,599 (1TB) and $3,199 (2TB) in the US, with a limit of two per customer.
• Screens: a 5.4-inch outer display and a 7.6-inch inner display that Apple says is 50% larger than the iPhone 18 Pro Max screen.
• Availability: limited walk-in stock in the US, UK, Canada, Australia, Mexico and much of Europe; new US online orders are quoted for late January.
• Key trade-offs: Touch ID in the side button instead of Face ID, and no dedicated telephoto camera.
• Market forecast: IDC expects Apple to take 44% of foldable market value in 2026 on 31% of units.

How we got here

Apple unveiled the Duo on September 9, calling it "the first foldable iPhone" in its official announcement. It was one of the first major launches for new CEO John Ternus, the former hardware chief who took charge in September.

Pre-orders opened on Friday, October 16. Within the first 30 minutes, shipping estimates for new orders slipped to January 25, according to MacRumors. Apple described the response as "nothing short of extraordinary," Reuters reported.

Samsung and Huawei have sold premium foldables for years. Apple is arriving late and betting that a more polished device, plus the pull of the iPhone brand, will bring the format to a much wider audience.

A launch defined by scarce supply

The clearest story on day one is demand outrunning supply. Bloomberg's Mark Gurman wrote that the phones are hard to produce because of the advanced hinge and new display technology, and that they are built in only a limited number of facilities in China.

That shortage brought back a sight that had mostly disappeared from Apple launches: queues. At the Fifth Avenue store in New York, a line of customers without pre-orders had grown to more than a few dozen people by early Thursday evening, Bloomberg reported. Reuters found several dozen fans queuing overnight in pouring rain outside London's Regent Street store, and a line outside the Sydney store, the first in the world to open, before 8 a.m. local time.

Where you can and can't walk in

Apple said walk-in sales would be possible in the US, UK, Canada, Australia, Mexico and several European countries. In mainland China, France, Hong Kong, India, Japan, Malaysia, South Korea, Taiwan, Thailand and the UAE, customers need a pickup reservation from an online order.

Stock varies widely by store. MacRumors bought a Duo at Apple's Edinburgh store early on Friday with no problem, and staff there said they had received more units than expected. Apple's US online store had told customers to check back on Saturday, October 24 for pickup reservations, a hint that stock may be topped up.

Resellers are already circling. In Hong Kong, one buyer told Reuters he planned to flip his HK$17,499 256GB unit for a profit of around HK$4,000.

What reviewers liked

Early reviews broadly agree that the hardware is unusually polished for a first-generation foldable. Tom's Guide's Mark Spoonauer gave it an Editor's Choice award and called it "the best designed foldable phone I've ever tested," praising a nano-texture matte screen that hides the crease better than any rival he has tried.

Battery life was a pleasant surprise. In the Tom's Guide review, which surfs the web at 150 nits over 5G until the battery dies, the Duo lasted 13 hours and 20 minutes. Samsung's Galaxy Z Fold 8 managed 10 hours and 6 minutes in the same test, while the iPhone 18 Pro Max reached about 17.5 hours.

Apple says the phone uses one battery on each side of the hinge, rated for up to 24 hours of use per charge when both displays are used equally. It also claims a charge to 50% in around 20 minutes with a wired charger.

Durability is another selling point. The Duo has a grade 5 titanium frame and an IP68 dust and water rating, compared with the Fold 8's water-only IP48 rating. Apple says the hinge is made from more than 100 components.

The compromises buyers should know about

The Duo is not a straight upgrade from a standard iPhone. The biggest change is Touch ID, which sits in the side button and replaces Face ID. Spoonauer called the switch "a downgrade" because of a small but noticeable unlock lag, though the phone can also be unlocked with an Apple Watch.

The camera system is also a step down from Apple's Pro models. The Duo has two 48-megapixel rear cameras, a main and an ultra wide, but no dedicated telephoto lens. Apple instead offers an "optical-quality 2x Telephoto" crop from the main sensor.

Then there are apps. Software that hasn't been updated for the 7.6-inch inner screen appears letterboxed, with black bars on the sides, MacRumors' review roundup noted. Tom's Guide found that well-known apps such as Slack, Instagram and TikTok already use the full screen, while others like YouTube still don't.

The critics' view

Some prominent reviewers were blunt. The Verge's Nilay Patel and Allison Johnson wrote that the phone "is expensive, it's full of compromises, and it can be incredibly frustrating to use," while adding that its risk and weirdness are "also fun."

Longtime Apple commentator John Gruber said it felt like using "an extraordinarily polished prototype — not a finished product that I'd want to buy and carry," according to Reuters. Marques Brownlee said that for a regular person who mostly texts and browses, "it is probably a no."

Apple's launch tactics have drawn criticism too. Gurman called the decision to open pre-orders before more inventory was ready a "major mistake," MacRumors reported.

What it means for you

If you are in the US, UK, Canada or Australia, you are in one of the markets where walk-in purchases are allowed. But don't count on finding your preferred model. Some commenters on MacRumors said their local store had only the most expensive 2TB version left for walk-in buyers.

Prices outside the US are steep too. A Sydney buyer told Reuters he paid A$3,899 for the 512GB model. In the US, Apple's leasing program with Klarna starts at $57.99 a month over 24 months, according to Apple.

For most people, the practical choice is still a regular iPhone. 9to5Mac's review called the Duo "a glimpse at the future of the iPhone" but said a traditional model remains the sensible purchase for now. If you mostly text, browse and use the zoom lens, waiting for a second generation is reasonable.

For developers, the message is clear: optimized apps look far better on the inner screen. Apps need to be rebuilt with the iOS 27.1 SDK, Apple's software toolkit, to fill the display properly.

Analysts expect Apple to lead the category

Market researcher IDC is bullish. Its vice president Francisco Jeronimo said Apple "has made a convincing case for this form factor," and IDC expects Apple to become the foldable market leader by both value and units in 2027, according to Reuters.

He added a caution: "Now comes the next test: turning excitement into availability, adoption and a lasting new chapter for the smartphone market."

Pricing pressure is industry-wide. Bloomberg noted that rivals including Samsung have also been raising prices, as memory chip shortages push up the cost of consumer electronics.

What happens next

Several dates are worth watching:

• October 24: Apple's US online store pointed customers to Saturday for new pickup reservations.
• November 2: Apple reports quarterly results. Those numbers won't include Duo sales, because the quarter ended around late September.
• Later this year: Apple says the Duo will gain support for Apple Pencil with USB-C, and a Reachability feature is also promised.
• Late January: the current delivery window for new US online orders, though some early buyers have seen estimates move up to November or December.

The open question is how quickly Apple can scale hinge and display production. Until it does, the Duo will be easier to read about than to buy.

The bottom line

The iPhone Duo is a hit on demand, a strong first effort on hardware and a work in progress on software. Here is what to do if you're interested:

1. Check pickup reservations online before you queue. Walk-in stock is limited and varies by store and by storage size.
2. Decide whether Touch ID and the missing telephoto lens are deal-breakers before spending $1,999 or more.
3. Look at whether your most-used apps are optimized for the inner screen, since letterboxed apps waste much of the display.
4. Be wary of resellers. Scalpers are already marking up units, and Apple's own delivery dates may improve.
5. If you're on the fence, wait. More stock, more optimized apps and Apple's next update are all on the way.
