Quick answer: Apple’s first foldable iPhone, the iPhone Duo, starts at $1,999 in the U.S. Preorders opened October 16, and Apple says availability begins October 23 in more than 70 countries and regions, including India. Its headline advantage is a 7.6-inch inner display that folds down to a 5.4-inch outer screen. The trade-off: MacRumors’ comparison with the iPhone 18 Pro lists features the Duo does not have, including a dedicated telephoto camera and Face ID.

What is the iPhone Duo?

The iPhone Duo is Apple’s first foldable iPhone. Open, it provides a 7.6-inch inner screen for video, games and multitasking; closed, it has a 5.4-inch outer display. Apple says the model is powered by its A20 Pro chip and has a dual-battery design. The company positions it as a large-screen iPhone that still fits in a pocket.

Apple’s U.S. starting price is $1,999 for 256GB of storage. Preorders began on October 16, and the company’s announced availability date is October 23. Apple says the initial rollout covers more than 70 countries and regions, including India, the U.S., the U.K., Canada, Japan and Australia.

What does the iPhone Duo give up?

The foldable display is the main attraction, but buyers comparing it with Apple’s iPhone 18 Pro line should look closely at the camera and controls. MacRumors’ published specification comparison identifies several Pro features that are absent from the Duo:

  • No dedicated telephoto camera: MacRumors says the iPhone 18 Pro offers up to 8× optical zoom, while the Duo’s main camera provides “optical-quality” 2× zoom.
  • No Face ID: The comparison says the Duo uses Touch ID instead.
  • No Action button or LiDAR scanner: Those features are listed for the Pro model, not the Duo.
  • Fewer pro camera options: MacRumors lists ProRAW, ProRes RAW and some other Pro camera features among the omissions.

Those are specification comparisons, not a hands-on verdict about photo quality or reliability. Apple’s pitch is different: a larger folding display, a new way to use iOS, and a device that can shift between a compact phone and a bigger screen.

Is a $1,999 foldable iPhone for everyone?

Probably not—and that may be the point. CNET’s consumer analysis described the Duo as a premium option for people who specifically want a foldable iPhone, rather than a replacement for every iPhone. CNET cited Counterpoint Research’s estimate that foldables account for about 2% of the smartphone market, underscoring how specialized the category remains.

For shoppers who value a large screen for multitasking and media, the Duo offers a new form factor inside Apple’s ecosystem. For buyers who prioritize telephoto photography, Face ID or a lower price, the iPhone 18 Pro line may be a better fit. The practical question is whether the foldable screen is worth paying for—and which familiar Pro features you are willing to trade away.
