About the release
Apple's first-ever foldable iPhone is here. The iPhone Duo was unveiled on 9 September 2026 and arrives at retail Friday 23 October 2026, with pre-orders opening today (Friday 16 October). Starting price £1,999, placing it at the top of the iPhone range alongside the Pro Max tier. This is a book-style folding dual-display system: a 7.6-inch Super Retina XDR inner display (around 50% larger than the iPhone 18 Pro Max) and a 5.4-inch outer display (90% of the screen area of the iPhone 18 Pro), both running the same aspect ratio so content scales cleanly between them.
Under the hood: the A20 Pro chip built on 2nm process technology (6-core CPU up to 20% faster than A19 Pro, 7-core GPU up to 40% faster), dual high-energy batteries (one each side of the hinge) delivering up to 31 hours video playback on the inner display or 44 hours on the outer, a Grade 5 titanium enclosure with mirror-polished finish, a 3D-printed hinge cover, Ceramic Shield 2 front (3x better scratch resistance than previous gen) and IP68 water resistance. The camera system runs a 48MP Fusion Main and 48MP Fusion Ultra Wide (optical-quality 2x zoom, no dedicated telephoto), plus a Center Stage front camera and a new FaceTime camera hidden beneath the inner display. Ships with iOS 27.1, Apple Intelligence and the beta Siri AI build. Colours: Star White and Night Sky at launch, with additional colourways confirmed to follow.

Release date and UK pricing
Pre-orders open today, Friday 16 October 2026 via apple.com/uk and the Apple Store app. The wider UK release follows on Friday 23 October 2026 at Apple retail and selected Apple-authorised retailers. Starting price is £1,999 at the 256GB tier, with 24-month financing available from £66.63 per month. Storage goes up through 512GB, 1TB and 2TB — full tier pricing has not been published yet. Launch colours: Star White and Night Sky, with Apple confirming additional colours to follow after launch window.
For context, the £1,999 starting price lands the Duo above the standard iPhone 18 Pro Max tier but — given Apple's first foldable positioning — below where many analysts had projected pre-reveal. Compared to competing foldable flagships from the Samsung Galaxy Fold line (recent generations have hovered around £1,800) and Huawei's Mate X series (regularly over £2,000 in regions where available), the Duo sits competitively on paper, with the Apple ecosystem and iOS 27.1 as the primary differentiators. Expect pre-order allocation to clear rapidly through launch window as the first proper Apple-ecosystem foldable landing in a market that's been waiting on this specific product for several years.
Design and details
Apple's foldable approach differs from most of what's been on the market so far in a few key ways. The dual-display aspect ratio match is deliberate: content moves between inner and outer displays without reflowing, which handles one of the main friction points on competing foldables. The hinge and the under-display camera are the two most-engineered details.
The dual-display system
The 7.6-inch inner display is a Super Retina XDR foldable OLED running ProMotion at up to 120Hz with Always On, 3000 nits peak outdoor brightness and a nano-texture finish that reduces glare. Apple is calling it around 50% larger than the iPhone 18 Pro Max — making this the biggest Apple phone display ever shipped. The 5.4-inch outer display runs the same Super Retina XDR spec sheet and delivers roughly 90% of the iPhone 18 Pro's screen area. Because both displays share the same aspect ratio, apps scale between them without reflowing — Apple's answer to one of the longest-standing foldable usability issues. Split View multitasking arrives on iPhone for the first time, letting you run two apps side by side on the inner display. Apple Pencil (USB-C) support is confirmed to arrive later this year.
A20 Pro + dual-battery engineering
The A20 Pro chip built on 2nm process technology is Apple's most advanced silicon to date — a 6-core CPU running up to 20% faster than A19 Pro, a 7-core GPU up to 40% faster and more power efficient, and a Dual 16-core Neural Engine with 2x the compute. 50% more unified memory bandwidth and up to 35% better sustained performance than iPhone 17 Pro. Thermals are handled by a custom vapour chamber and a new chip package. The dual-battery system is a direct engineering solution to the foldable form factor — two high-energy batteries, one on each side of the hinge — delivering up to 31 hours of video playback on the inner display, 44 hours on the outer display and 24 hours with both displays used equally. The eSIM-only global design is partly what makes those battery figures possible, freeing up the internal space traditionally used by SIM trays.
Titanium build, Ceramic Shield 2 and the hinge
The enclosure is Grade 5 titanium with a mirror-polished finish, with a 3D-printed hinge cover carrying a micro-blasted finish. Ceramic Shield 2 on the front brings 3x better scratch resistance than the previous generation, with Ceramic Shield on the back. The hinge itself is built from over 100 individual components, with a centre-supporting design and magnet array that keeps the device aligned when folded. The inner display stack uses high-strength glass layers, a custom polymer cover and a titanium plate at the bottom — the engineering investment here is where Apple is specifically trying to differentiate from the perceived delicacy of earlier-generation foldables. The device carries IP68 water, splash and dust resistance — the first foldable from any major manufacturer to achieve the IP68 standard on a book-style folding form factor.

Camera system and foldable-exclusive features
The camera hardware is a 48MP Fusion Main camera (zero shutter lag, 24MP default output, optical-quality 2x telephoto crop) paired with a 48MP Fusion Ultra Wide that handles macro work. Front: Center Stage front camera on the outer, plus a new under-display FaceTime camera hidden beneath the inner display — a first for iPhone. Video runs up to 4K120 in Dolby Vision on the main. Notable omission for a flagship at this price: no dedicated telephoto lens — the 2x reach is handled by the Fusion Main's optical-quality crop rather than a separate lens, likely a space-saving decision given the foldable form factor.
Where the foldable design properly earns its space is in the exclusive camera features. Smart Take uses both displays simultaneously for subject preview. Duo Preview shows the person being photographed a live preview on the outer display while the photographer frames on the inner. Kid Cue plays attention-grabbing animations on the outer display to catch children's attention during photos. Duo FaceTime uses both cameras simultaneously for multi-angle calls. These are the kind of software features that only exist because of the hardware form, which is where the Duo starts to feel like more than just a bigger-screen iPhone.
Why this release matters
The iPhone Duo is Apple's first foldable, closing the gap on a product category Samsung has had the field to itself in for the better part of six years. Pre-reveal, this was one of the most-tracked unreleased Apple products in the company's history — rumours and leaks have been running since 2022. Apple's deliberate decision to wait until the hinge engineering, dual-display aspect ratio matching and under-display camera technology were all solved to the standard they wanted is a textbook Apple product-cycle move: enter late, enter at an engineering standard that reframes the category.
The £1,999 starting price is also notable. It's not an impulse purchase at that tier, but it's not the £2,500+ most analysts had projected either. By pricing it in line with other high-end foldables rather than above them, Apple is signalling that it wants proper first-generation adoption numbers rather than treating this as a niche prestige product. Combined with the first proper Apple ecosystem foldable implementation (iOS 27.1, Apple Intelligence, Split View multitasking, seamless Apple Watch unlock), this launch has the potential to double the overall global foldable market in its first 12 months on sale. Pre-order allocation will be the single tightest supply constraint — anyone wanting a launch-day pair should move fast on today's pre-order window.
