The Apple iPhone Duo is the most significant iPhone in Apple's history since the original — the world's first foldable iPhone, combining Apple's most advanced display engineering, A20 Pro silicon, a breakthrough precision hinge, dual built-in batteries and iOS 27 reimagined for a foldable form factor in a grade 5 titanium frame polished to a mirror finish, available exclusively in two refined colours: Night Sky and Star White. Open, the iPhone Duo becomes the thinnest iPhone Apple has ever made at just 5.2 millimetres — revealing a 7.6-inch Super Retina XDR OLED inner display with 1878 × 2670 pixel resolution at 430 PPI, nano-texture finish that eliminates glare unlike any previous iPhone display, ProMotion technology with adaptive 120Hz, Always-On display, Dynamic Island and 3,000 nit peak brightness outdoor — a display that rivals dedicated tablets in size and exceeds every previous iPhone in visual quality per square centimetre. Closed, the iPhone Duo becomes a pocketable 84.1mm-wide device with a 5.4-inch outer Super Retina XDR OLED display at an even higher 460 PPI delivering 90 percent of the screen area of iPhone 18 Pro in compact form — with the same aspect ratio as the inner display so content scales proportionally and visual continuity is maintained perfectly between the two screens. Both displays share ProMotion 120Hz, Always-On capability, Dynamic Island, True Tone, wide colour P3, the same 3,000/1,600/1,000 nit brightness hierarchy and 2,000,000:1 contrast ratio — making the iPhone Duo the only device that delivers two flagship-class screens in a single device that fits in a pocket.

The A20 Pro chip with 6-core CPU featuring 2 super cores and 4 efficiency cores, 7-core GPU with Neural Accelerators, dual 16-core Neural Engine and hardware-accelerated ray tracing is the most powerful chip Apple has ever put in an iPhone — powering every aspect of the Duo's experience from the ProMotion refresh coordination of two simultaneous displays to the on-device Apple Intelligence and Siri AI models, the Dual Fusion camera's 48MP computational photography at full resolution and the real-time visual intelligence capabilities that iOS 27's reimagined interface demands. Duo Preview is the camera innovation unique to the iPhone Duo's foldable form factor — using the folded hinge angle to position the camera in ways that are physically impossible on any other iPhone, enabling the outer display to act as a viewfinder for the rear camera system during self-portrait and group shooting, allowing subjects to see their preview on the outer display while the photographer uses the inner display for precise composition control, and unlocking new shooting perspectives that the fixed flat form factor of every other iPhone cannot achieve. The 48MP Dual Fusion camera system delivers triple-camera versatility from two lenses — the 48MP Fusion Main at 26mm f/1.6 with sensor-shift OIS serving as both the primary and as the optical path for a 12MP optical-quality 2x Telephoto at 52mm, while the 48MP Fusion Ultra Wide at 13mm f/2.2 with 120-degree field of view and Hybrid Focus Pixels completes a 4x optical-quality zoom range from ultra-wide to telephoto. Smart Take, Smart focus tracking, Photographic Styles 3 and every computational photography capability from Photonic Engine to Deep Fusion and Smart HDR 5 apply across all focal lengths. 4K Dolby Vision video records at up to 120fps from the Fusion Main, with Cinematic mode at up to 4K 60fps and Dual Capture simultaneously recording from front and rear cameras. The outer 12MP Center Stage camera and the inner under-display FaceTime camera at f/1.8 enable Duo FaceTime — a new video calling experience unique to the foldable form factor.

The dual built-in lithium-ion battery architecture delivers up to 24 hours of typical use, up to 44 hours of continuous video playback on the outer display and up to 31 hours on the inner display — the most battery life Apple has ever delivered in an iPhone, made possible by the physical space the foldable form factor creates for a dual-cell configuration that a single flat chassis cannot accommodate at equivalent thickness. Fast charging reaches 50% in approximately 20 minutes with a 60W or higher USB-C adapter, MagSafe and Qi2 both provide 25W wireless charging, and USB-C with USB 3 at up to 10Gbps handles both fast charging and DisplayPort video output. Touch ID fingerprint sensor built into the side button provides biometric authentication in the natural grip position for a foldable device — the first iPhone since the SE series to use Touch ID alongside Face ID capability in the TrueDepth camera. IP68 water and dust resistance to 6 metres for 30 minutes, Wi-Fi 7 (802.11be), Bluetooth 6, Thread networking, second-generation Ultra Wideband, Apple C2 cellular modem with 5G, NFC with Express Cards, dual-frequency GPS across GPS/GLONASS/Galileo/QZSS/BeiDou/NavIC and Emergency SOS, Roadside Assistance and Find My via satellite — all free for two years — complete the most comprehensively specified iPhone Apple has ever released. Apple Pencil (USB-C) support is coming later this year. Pre-orders begin October 16, 2026.
