Apple unveils iPhone Duo

CUPERTINO, CALIFORNIA Apple today introduced iPhone Duo, the first foldable iPhone. Opened, it is the thinnest iPhone ever, with a 7.6-inch inner display that provides a large canvas for viewing content, gaming, and multitasking, and a special nano-texture finish that minimizes glare for an unparalleled viewing experience. Closed, the 5.4-inch outer display delivers 90 percent of the screen area of iPhone 18 Pro in a compact, pocketable design.¹ Both displays share the same aspect ratio, so content scales proportionally, ensuring visual continuity. iPhone Duo is built to last with an innovative hardware design and a precision hinge that offers a smooth, satisfying feel with every use. Powered by the new A20 Pro, iPhone Duo features an advanced thermal management system with a custom-designed vapor chamber and a dual-battery architecture, delivering pro performance and impressive all-day battery life. The advanced camera system takes stunning photos and videos, with the folding design unlocking fun new ways to use the camera that aren’t possible on any other iPhone. iOS 27 is reimagined, remaining familiar and intuitive while adapting to the versatile ways users can interact with iPhone Duo. And with Apple Intelligence² and Siri AI,³ iPhone Duo brings powerful AI capabilities together with a user’s personal context.

iPhone Duo is available in two refined colors: star white and night sky. Pre-orders begin Friday, October 16, with availability beginning Friday, October 23.

“iPhone Duo is the most transformational change to iPhone since the original. With an entirely new design and intuitive experiences, it shows what’s possible when hardware and software are engineered together and redefines what it means to use a foldable phone,” said John Ternus, Apple’s CEO. “With the largest display ever on iPhone that still fits easily in your pocket, combined with the power of A20 Pro, iPhone Duo helps you stay more immersed and productive wherever you go, whether you’re enjoying content, multitasking across apps, or gaming.”

iPhone Duo delivers Apple’s largest iPhone display in an entirely new design. Closed, iPhone Duo is comfortable to use one-handed and fits easily in a pocket, with a 5.4-inch outer Super Retina XDR display that provides 90 percent of the screen area of iPhone 18 Pro. Opened, the 7.6-inch inner Super Retina XDR display is 50 percent larger than iPhone 18 Pro Max, offering an immersive canvas for everything users do. A premium nano-texture finish reduces glare and reflections, creating a matte surface that minimizes crease visibility and feels great to touch. Beneath the inner display, a new FaceTime camera stays hidden when not in use to keep the screen uninterrupted. Both displays share the same aspect ratio, designed for how people use their iPhone, so the experience feels continuous whether iPhone Duo is open or closed. The displays also feature ProMotion, Always On, and 3000 nits of peak outdoor brightness. Later this year, iPhone Duo will support Apple Pencil with USB-C, allowing users to take notes, sketch, or mark up documents on either display.

Touch ID is integrated into the side button for easy, secure, and consistent authentication whether iPhone Duo is open or closed, and users can unlock iPhone Duo using their Apple Watch. The design also features Camera Control to quickly launch the camera, including the brand-new Siri Camera mode, which lets Siri see what the user sees to answer questions and take action.

iPhone Duo is built to last and feels exceptionally solid with every use. It’s crafted from grade 5 titanium for incredible strength, with an enclosure that has an elegant mirror-polished finish and a 3D-printed hinge cover with a contrasting micro-blasted finish. Ceramic Shield protects the back of iPhone Duo, and Ceramic Shield 2 on the front has 3x better scratch resistance than the previous generation. iPhone Duo is also splash-, water-, and dust-resistant with an IP68 rating.⁴ The hinge is engineered from more than 100 components to precisely control opening and closing and support the center of the display, delivering a smooth, satisfying feel. Internally, support ribs reinforce the structure for added stiffness, while antenna splits with ceramic fiber inserts enhance the frame’s rigidity.

The inner display is designed to withstand the wear of everyday use. A scratch-resistant coating and a nano-textured cover layer — made from a custom polymer with up to 40 percent higher stiffness than other materials used in the industry — protect the surface. High-strength glass sits above and below the folding display panel, with custom adhesives that allow the layers to glide past one another like the pages of a book, relieving bend stress, and a titanium plate at the bottom further enhances durability.

iPhone Duo delivers an advanced camera system that brings all-new experiences made possible by its breakthrough design. With the new 48MP Fusion Main camera, users can shoot sharp photos at up to 48MP resolution with zero shutter lag, capture in the 24MP default for incredible image quality at a file size perfect for sharing, and get closer to the subject with an integrated optical-quality 2x Telephoto. The 48MP Fusion Main camera also benefits from a new computational image pipeline for sharp details, and excels in low light thanks to a large sensor, fast aperture, and sensor-shift optical image stabilization.

The 48MP Fusion Ultra Wide camera — the same as on iPhone 18 Pro models — captures wider fields of view and enables macro photography, while the Center Stage front camera can automatically take photos and videos in any orientation, so users don’t have to rotate iPhone for landscape selfies. Upgraded Photographic Styles with new texture and grain controls let users further dial in their desired appearance and have more creative control over their photos.⁵ Under the inner display, a new FaceTime camera helps users connect with friends and family whether iPhone Duo is held open or propped on a surface for hands-free calls.

The foldable design with dual displays unlocks camera experiences that are not possible on any other iPhone.

• With Smart Take, users no longer miss out on being in the photo because they are behind the shutter or racing to beat a timer. On-device AI models running on A20 Pro analyze the scene in real time and automatically capture photos when subjects are posing.

• Users can take a selfie with the higher-resolution rear cameras and preview their shot on the outer display.

• Duo Preview shows the live preview on the outer display, helping subjects pose, check their framing, and guide the shot.

• Kid Cue plays animations from Peanuts on the outer display to grab the attention of children so they look at the camera.

• Duo FaceTime lets people who are with the user join a video call on the outer display, so everyone can share the moment without crowding around one screen.

iPhone Duo supports 4K120 fps recording in Dolby Vision on the 48MP Fusion Main camera, unlocking gorgeous slow-motion effects by adjusting the playback speed. Users can now apply Cinematic effects after capture at up to 60 fps, and Audio Mix introduces new algorithms that deliver higher-quality voices and can now isolate music. Time-lapse supports 4K in Dolby Vision HDR, and users can prop iPhone Duo up without needing a tripod to easily capture longer-duration videos.

iOS 27 is tailored for iPhone Duo, delivering a familiar and intuitive experience that introduces new ways to interact with iPhone. Lock Screen controls, the Dock on the Home Screen, and app navigation and controls now appear on the side to maximize vertical space for content. When iPhone Duo is open, the display shows two Home Screen pages with Today View — a vertically scrolling list of customizable widgets — on the left. The status bar includes a circular, flexible system that nestles into the corner of the screen, showing relevant information like Wi-Fi, cellular strength, battery, and more. The Dynamic Island is also redesigned to fit vertically on the side of the outer and inner displays, and expands to show Live Activities and alerts. iOS seamlessly adapts to the new ways to use iPhone Duo — content reacts as it folds, reorients when turned to the side, and switches to the appropriate display when flipped over.

Apple apps are optimized for iPhone Duo, and developers can easily adapt their apps using the new and updated APIs in the latest SDKs, and upcoming support for iPhone Duo in Device Hub in Xcode. Third-party apps, including Netflix, Zoom, and Slack, are already taking advantage of the folding design to deliver immersive experiences that make the most of the larger display and new ways to use iPhone Duo.

The expansive display supercharges productivity, letting users do more at once with new multitasking capabilities. Split View allows users to open two apps side by side on iPhone for the first time. Users can also quickly swap between apps; open two windows of the same app, like Safari; easily have a conversation with Siri AI while looking at content on the other side of the screen; and save pairs of apps to come back to later.

StandBy gets a major upgrade on iPhone Duo. Set iPhone Duo down and it enters StandBy on either the outer or inner display — even when it’s not charging — turning the device into a photo frame, hub for widgets, clock, and more. New Calendar and Weather faces join existing Clock and Modular faces, while the Photos face is updated to display Shared Albums. Every face now offers deeper customization, with new colors, fonts, and complications to choose from.

iPhone Duo gives users access to Siri AI, an entirely new version of Siri that is rolling out in beta with iOS 27. Powered by Apple Intelligence, Siri is profoundly more personal, capable, and conversational, and becomes even more useful on the large inner display. Powerful AI capabilities paired with personal context make iPhone Duo an intelligent personal hub with privacy and security at its core.

Siri AI can draw on personal context understanding to help users find what they need in the moment across messages, emails, photos, and more; use onscreen awareness to take action related to the content on a user’s screen; and answer questions about virtually any topic. Users can write with Siri by simply describing what they need. The all-new Siri app also makes it easy to revisit past conversations or kick off new ones, with conversational history synced privately across products with iCloud.

Additionally, Apple Intelligence makes apps smarter and more useful. Users can improve the composition of a photo after it’s been taken with Spatial Reframing, Extend, and upgraded Clean Up. Image Playground also now offers photorealistic imagery, and with upcoming support for the SynthID standard, users can identify images generated or edited with AI.⁶ In Safari, Notify Me helps users monitor web pages for changes, like product restocks or price drops, to stay on top of updates. To protect users’ privacy, Apple Intelligence uses on-device processing and Private Cloud Compute, which extends the privacy and security of iPhone into the cloud.

Powered by A20 Pro — the same chip in iPhone 18 Pro models — and paired with an advanced thermal management system, iPhone Duo delivers up to 35 percent better sustained performance than iPhone 17 Pro. A new chip package inspired by M-series Apple silicon connects A20 Pro directly to a custom vapor chamber, dissipating heat and powering multitasking, gaming, and complex AI workloads. A new display engine drives the inner and outer displays simultaneously and enables a fluid experience as users transition between them. The 6-core CPU is up to 20 percent faster than A19 Pro, delivering the fastest CPU in a smartphone; the 7-core GPU is up to 40 percent faster and more power efficient; and the new Dual 16-core Neural Engine offers 2x the compute power to run on-device AI models. A20 Pro also delivers 50 percent more unified memory bandwidth and is built on the latest 2-nanometer process technology.

iPhone Duo is designed with one high-energy battery on each side to maximize capacity while efficiently using internal space. A combination of Apple silicon and energy rebalancing algorithms allows the batteries to operate seamlessly as one, so users get up to 31 hours of video playback when using the inner display, up to 44 hours of video playback when using the outer display, and up to 24 hours of usage per charge when both displays are used equally.⁷ Users can also enjoy fast charging — iPhone Duo can charge up to 50 percent in around 20 minutes or wirelessly charge up to 50 percent in around 30 minutes with a MagSafe or Qi2 charger.⁸

iPhone Duo features an eSIM-only design worldwide that saves internal space to maximize battery capacity.⁹ eSIM offers greater flexibility, better security, and seamless connectivity compared to traditional physical SIM cards, and as an industry standard, it is supported by over 500 carriers around the world, including AT&T, T-Mobile, Verizon, and more. iOS 27 also introduces iPhone Handoff, which allows users with supported carriers to easily switch back and forth between two iPhone models with the same phone number.¹⁰

N1, an Apple-designed wireless networking chip, enables Wi-Fi 7, Bluetooth 6, and Thread, while C2, Apple’s next-generation cellular modem system, brings AI-powered improvements to cellular quality and reliability, and now supports mmWave in the U.S.

To complement iPhone Duo, Apple is introducing beautiful new accessories. The iPhone Duo Folio — available in navy blue and taupe — features an integrated kickstand that supports a wide range of angles for reading, viewing content, or FaceTime, and folds away neatly when not in use. The iPhone Duo Case — available in sand and navy blue — is thin and light, with a protective two-part design that wraps around both sides of the device. Both cases are compatible with MagSafe, Qi2 25W, and Qi-certified chargers. With built-in magnets that align perfectly with iPhone Duo, they offer a magical attach experience and fast wireless charging.

iPhone Duo was built with the environment in mind and drives progress toward Apple’s ambitious plan to be carbon neutral across its entire footprint by 2030. It is made with 35 percent recycled content overall,¹¹ including 100 percent recycled cobalt in the battery and 100 percent recycled titanium in the 3D-printed hinge cover. iPhone Duo is manufactured with 60 percent renewable energy, like wind and solar, across the supply chain, and meets Apple’s high standards for energy efficiency and safe chemistry. Like all Apple products, its paper packaging is 100 percent fiber-based¹² and can be easily recycled at home.
