Apple introduces iPhone Duo, its first foldable iPhone

Apple has published a dedicated product page for iPhone Duo, describing it as "the first foldable iPhone." The page presents it alongside the existing iPhone 18 Pro line rather than as its replacement, comparing specifications between the two devices throughout.

Open, Apple says iPhone Duo has the largest and thinnest iPhone display ever, 50 percent larger than iPhone 18 Pro Max's screen. Closed, its outer display covers more than 90 percent of the screen area of iPhone 18 Pro. A comparison table lists a 7.6-inch display size for iPhone Duo, though the page does not say whether that figure describes the inner display, the outer display, or both. The inner display is built from 10 ultrathin layers with a custom nano-texture finish meant to reduce glare, and its FaceTime camera sits under the display, a feature iPhone 18 Pro does not have. Apple lists several use poses the hinge and iOS 27 enable: landscape for Split View multitasking, portrait for typing and browsing, closed for one-handed use, and "seated" and "standing" angles for watching video or using StandBy. For durability, the frame and hinge cover are Grade 5 titanium, the inner display carries a scratch-resistant coating, both faces use Ceramic Shield, and the phone is rated IP68 for water and dust resistance.

iPhone Duo runs the same A20 Pro chip as iPhone 18 Pro; Apple's feature copy adds that the chip includes a "Dual 16-core Neural Engine," though the page does not say whether that detail is specific to iPhone Duo or shared with iPhone 18 Pro, whose own spec row lists only "A20 Pro chip." The rear camera is a 48MP Dual Fusion system, a 48MP main lens plus a 48MP ultra-wide, with no telephoto lens and no variable aperture; it captures 48MP photos and 4K 120 fps video. iPhone 18 Pro's 48MP Pro Fusion system instead adds a telephoto lens and a variable-aperture main lens. Camera software adds several named features: Duo Preview and Kid Cue, Duo FaceTime for group calls, and Smart Take. The front camera is 12MP, against 18MP on iPhone 18 Pro. For power, Apple describes a dual-battery system it calls a first for iPhone, paired with a space-saving internal eSIM design to make more room for the batteries, and a C2 modem it says delivers "groundbreaking efficiency." The page states no battery life in hours for iPhone Duo, unlike iPhone 18 Pro's listed "up to 45 hours" of video playback. Fast wired charging reaches up to 50 percent in about 20 minutes.

On software, Apple positions Siri AI as a "new, more powerful" assistant, rolling out in English with usage limits that may apply, alongside existing Apple Intelligence features for photo editing, Writing Tools, Visual Intelligence, and child safety tools. Connectivity includes Wi-Fi 7, Bluetooth 6, 5G, eSIM, and satellite messaging. iPhone Duo ships in two colors, Night Sky and Star White. Apple also states the device is made with 35 percent recycled material by weight, including 85 percent recycled titanium in the enclosure, is manufactured using 60 percent renewable electricity, and ships in fully fiber-based packaging.

The page gives no price and no release date, linking to a "View pricing" page rather than stating a figure. It names no Apple executive or spokesperson: the text is Apple's own marketing copy throughout, and "the first foldable iPhone" is Apple's own framing rather than an independently verified claim. Apple also states that, because it's an iPhone, iPhone Duo "holds its value longer than other smartphones," a line the page does not back with any figures.

Key facts

  • Apple's product page introduces iPhone Duo as "the first foldable iPhone," sold alongside the existing iPhone 18 Pro line rather than replacing it.
  • Open, its display is 50 percent larger than iPhone 18 Pro Max's; closed, the outer display covers more than 90 percent of the screen area of iPhone 18 Pro.
  • It runs the same A20 Pro chip as iPhone 18 Pro, but its 48MP Dual Fusion rear camera drops the telephoto lens and variable aperture that iPhone 18 Pro's 48MP Pro Fusion system has.
  • Apple gives no price or release date, only a "View pricing" link, and states no battery life in hours for iPhone Duo, unlike iPhone 18 Pro's listed 45 hours of video playback.
  • Siri AI, pitched as a "new, more powerful" assistant, is rolling out in English only, with usage limits that may apply.

Why it matters

iPhone Duo is Apple's first entry in the foldable phone category, and the company frames it as a straightforward addition to the lineup rather than a separate or experimental device: it appears alongside iPhone 18 Pro on Apple's own comparison page throughout, and runs the same A20 Pro chip. The pitch leans on the outer display, which Apple says covers more than 90 percent of the screen area of iPhone 18 Pro, so the phone is designed to work closed for most everyday tasks and open mainly for the moments that benefit from more room: video, games, and side-by-side apps through Split View. Apple also pairs the fold with new interaction poses built into iOS 27, such as standing the phone up for hands-free video calls or laying it flat at an angle to watch a show, treating the hinge as a way to reposition the phone and not only a way to get a bigger screen.

Who it affects

The page includes a section titled "Switch from Android to iPhone Duo," explicitly pitching the device at Android owners considering a move to iPhone. Existing iPhone 18 Pro Max buyers get a direct point of comparison, since Apple sets the two phones side by side on specs rather than positioning iPhone Duo as a strict replacement. Apple also sells dedicated accessories for it, an iPhone Duo Case and a Folio with a retractable kickstand, separate from iPhone 18 Pro's accessory line. Siri AI, pitched as part of the package, is rolling out in English only for now, which limits who can use the new assistant at launch regardless of which phone they buy.

How to use it

iPhone Duo folds between several stated positions: landscape for immersive video or two apps side by side in Split View, portrait for typing and browsing, closed for one-handed use with controls moved to the side, "seated" for watching a show or a workout at an angle, and "standing" for a bedside clock or widgets through StandBy. It ships in two colors, Night Sky and Star White. Apple gives no price and no release date on the page, only a "View pricing" link, so anyone deciding whether to buy has to wait for those details elsewhere. Fast wired charging is rated to reach up to 50 percent battery in about 20 minutes.

How solid is it

Every claim on the page is Apple's own: the text names no executive, engineer, or outside reviewer, and "the first foldable iPhone" is Apple's own framing rather than an independently checked fact. Some specifics are also underspecified even within Apple's own comparison table: it lists a 7.6-inch display for iPhone Duo without saying whether that is the inner display, the outer display, or both, and it credits the A20 Pro chip with a "Dual 16-core Neural Engine" without saying whether that applies only to iPhone Duo or to iPhone 18 Pro as well. The page also carries unsupported marketing claims alongside its specs, such as the assertion that iPhone Duo "holds its value longer than other smartphones" because it's an iPhone, a line the page does not back with any figures.

Risks and caveats

Buyers have real gaps to work around before ordering: no price, no release date, and no battery-life figure for iPhone Duo, where iPhone 18 Pro's own row in the same table states "up to 45 hours" of video playback. Siri AI's rollout is capped to English only at launch, and Apple notes usage limits may apply on top of that. The front camera is lower resolution than iPhone 18 Pro's, 12MP against 18MP, and the rear camera also gives up the telephoto lens and variable aperture that iPhone 18 Pro's camera system has.
