In short: the iPhone Duo, Apple’s first foldable phone, went on sale on October 23, 2026 from $1,999 (256GB). Demand outstripped supply: deliveries in the US and UK are quoted for late January 2027. Reviews praise the display and build, but some early owners have reported cracks on the inner screen, and on October 26 Apple acknowledged an issue affecting a small number of units.

How much does the iPhone Duo cost?

  • 256GB — $1,999 / £1,999;

  • 512GB — $2,199;

  • 1TB — $2,599;

  • 2TB — $3,199.

That is about $700 more than the iPhone 18 Pro Max. Still, the price landed at the low end of forecasts: IDC expected Apple to charge $400 more than Samsung’s Galaxy Z Fold8 Ultra, and it came in $100 below. No power adapter is included.

What can the first foldable iPhone do?

The Duo opens like a book: a 5.4-inch outer screen and a 7.6-inch inner screen with an anti-glare nano-texture finish, both OLED at up to 120Hz. Unfolded it is just 5.2mm thick; folded, 11.3mm, at 254g. The frame and hinge cover are titanium, rated IP68. Inside are the 2nm A20 Pro chip, Apple’s own C2 modem and two batteries, one in each half.

The main trade-offs: Touch ID in the side button instead of Face ID, no telephoto lens (just 48MP main and ultra-wide cameras) and no Action button. It is eSIM-only.

What problems does the iPhone Duo have?

Some owners have reported cracks along the inner screen’s fold, sometimes with bright lines. On October 26, Apple said the issue affects a small number of units and advised affected customers to contact AppleCare for a replacement; the cause has not been confirmed. Out-of-warranty inner-display repair costs $999 in the US without AppleCare+, or $99 with it. The other issue is apps: many popular apps are not yet optimised for the large screen and show black borders.

What do the reviews say?

Scores are mostly strong: Engadget gave it 8.8/10, WIRED 7/10, and PCMag called it the best foldable on the market for hardware and battery life. Macworld, however, recommends waiting because of unready apps, the missing Face ID and open questions about first-generation durability.

FAQ

When can I get an iPhone Duo?

Does the iPhone Duo have Face ID?

No. It unlocks with Touch ID in the side button or with an Apple Watch.

Should I buy the iPhone Duo now?

If reliability and cameras matter most, the iPhone 18 Pro Max is better value. The Duo is for people who genuinely want a tablet in their pocket and accept first-generation trade-offs.
