Apple's first foldable iPhone is here

Apple held its autumn event at Apple Park on 9 September, and the headline was the company’s first foldable iPhone, the iPhone Duo, a 7.6-inch folding device priced at $1,999, alongside the conventional flagship of the season, the iPhone 18 Pro and Pro Max. For a company that watched the foldable category mature for seven years and repeatedly declined to enter it, the Duo is a decision made in public, and the event was effectively Apple’s statement about how it intends to do foldables: later, heavier and more expensive than everyone else.

The Duo is engineered like an Apple product and priced like one. Its inner display opens to 7.6 inches with a 5.4-inch cover screen, its hinges are titanium and glass, and it runs on the A20 Pro, Apple’s first two-nanometre chip, which the event also confirmed is exclusive to this generation of premium devices. The $1,999 price puts it at the top of the foldable market, above the current leaders, and the design choices, a book-style fold rather than a clamshell, and an emphasis on build quality over innovation, are recognisably Apple’s usual approach: let the category mature, then enter with a refined product and a premium position.

The iPhone 18 Pro, meanwhile, is a camera upgrade wrapped in a familiar body. The Pro line gains a larger main sensor, new telephoto hardware and variable aperture control, aimed squarely at the photography market that Apple has courted for years, alongside the expected silicon and battery improvements. The two announcements together make the strategy plain: the Pro line defends the volume premium market, while the Duo opens a new front at the top, and the company expects both to coexist in the same customer base rather than cannibalize it.

The event was also the first full showcase under John Ternus, who took over as chief executive in the spring, and the tone was notable for what it confirmed: a calmer, more staggered Apple, releasing products through the year rather than in a single September blast, with hardware and software features arriving in waves. The Duo launch was complemented by the roll-out of the AI features in iOS 27, which had been in beta since mid-September and which turn Siri into the kind of always-on agent the company has been promising, and both announcements were framed as the platform becoming something to live with rather than to buy once a year.

The commercial question the Duo raises is timing. Apple has entered foldables when the category is established, when rivals have worked through their quality problems, and when the price of admission has already been set at a level the market accepted. The argument for arriving late is that Apple’s brand and ecosystem let it charge a premium for a refined product; the argument against is that the category’s most eager buyers already own foldables, and that the Duo’s price invites comparisons the company may not want. The early reviews, the first of which are already circulating, have praised the build and the hinge while noting the price, which is roughly where every Apple foldable rumour for the past three years said the conversation would land.

The broader meaning of the event is that Apple is now committed to the foldable form factor, after years of insisting the technology was not ready. That commitment, priced at $1,999 and built on a two-nanometre chip, says as much about where the company thinks the premium market is heading as any product announcement in years. Whether the Duo becomes a category-defining hit or an expensive footnote will be settled in the sales charts, and the answer will shape the foldable market’s next generation, whichever way it goes.
