The announcement
Announced 9 September. On sale 23 October.
iPhone Duo was unveiled on Wednesday, 9 September 2026 at Apple Park during a live-streamed keynote titled “Surprise and Shine”. John Ternus, in his first keynote as CEO, revived Steve Jobs's “one more thing” to reveal it, and called it the most transformational change to iPhone since the original.
The name refers to the two displays and the two batteries. Apple's own tagline: Foldable. Posable. And durable.

02 · Design & build
5.2 mm open.
11.3 mm closed.
A book-style foldable. Closed, it is a short, wide device about the footprint of a passport. Opened, it is closer to a small tablet. Apple describes it as the thinnest iPhone it has made when open, and the largest display it has put on an iPhone.
DIMENSIONS
- Closed
- 117.8 × 84.1 × 11.3 mm
- Open
- 117.8 × 164.6 × 5.2 mm
- Weight
- 254 g
254 g is 5 g heavier than iPhone 18 Pro Max and 53 g heavier than Galaxy Z Fold 8 — the most-discussed physical trade-off, and the cost of the dual-battery system.
MATERIALS
- Frame
- Grade 5 titanium, mirror-polished
- Hinge cover
- 3D-printed titanium, micro-blasted
- Front (closed)
- Ceramic Shield 2
- Back
- Ceramic Shield
- Inner cover
- Nano-texture polymer over glass
- Internal
- Support ribs; ceramic-fibre antenna inserts
Mirror-polished titanium against a micro-blasted hinge cover is a deliberate two-texture contrast — one of the few purely aesthetic decisions Apple called out.
CONTROLS & PACKAGING
- Side button with integrated Touch ID
- Camera Control button
- Volume buttons on the top edge · USB-C
- No SIM tray, in any market
Putting the volume keys on the top edge means they always follow the direction you press: right for up, left for down. The rails are rounded to give a grip for opening.
To reach 5.2 mm, Apple packaged components into the camera plateau: the raised camera area doubles as internal volume.
03 · The displays
Two Super Retina XDR panels, one aspect ratio.
Both panels share the same aspect ratio so content scales proportionally rather than reflowing as you open and close the device. Both run ProMotion to 120 Hz, Always On, 1000 nits typical and 3000 nits peak outdoors.
OUTER · CLOSED 5.4″
- Measured
- 5.36″ rectangle
- Resolution
- 1398 × 2034
- Density
- 460 ppi
- Refresh
- ProMotion to 120 Hz
- Brightness
- 1000 / 3000 nits peak
- Protection
- Ceramic Shield 2
90 percent of the screen area of iPhone 18 Pro, in a body Apple says is comfortable one-handed and pocketable. The panel is not symmetrical: rounded along the right edge, squared off on the left. At 5.4 inches it is on the small side for the screen you will spend most of the day on, and the asymmetry is the device's most obvious visual flaw. Some buyers will never get past it.
INNER · OPEN 7.6″
- Measured
- 7.58″ rectangle
- Resolution
- 1878 × 2670
- Density
- 430 ppi
- Refresh
- ProMotion to 120 Hz
- Brightness
- 1000 / 3000 nits peak
- Finish
- Nano-texture, matte
50 percent larger than iPhone 18 Pro Max's display. A FaceTime camera sits beneath it, mid-way down the right-hand side, hidden when not in use: a first for iPhone. Closing the camera app dissolves the blacked-out pixels it shoots through back into the wallpaper. Keeping it hidden costs image quality, so it is a trade rather than a free win.
Nano-texture
Nano-texture: less glare, and less visible crease.
Nano-texture has appeared on Pro Display XDR, Studio Display and iPad Pro, never on an iPhone. It reduces glare and reflections, and it minimises crease visibility: a non-reflective surface has no continuous specular highlight running across it, which is exactly what makes a crease jump out on a glossy foldable. Johny Srouji described a perceptually flat matte surface that feels premium to the touch. Apple says the crease is reduced, not eliminated.
That is a fair description. This is among the least visible creases on any foldable so far, level with the Oppo Find N6. It has not gone — run a finger across the fold and you will find it — but it takes looking for. The coating earns its keep twice over: reflections are a non-issue in bright light however the device is held, and the surface is smooth enough that a finger glides across it.
04 · Hinge & durability
More than 100 parts, matched by AI, sealed to 6 metres.
The hinge controls opening and closing, supports the centre of the display to hold it flat, and works with an integrated magnet array for a secure closure. During manufacturing, AI algorithms match each hinge to its best-fit housing for alignment tolerance. Carbon fibre support plates inside the hinge are reported to contribute to crease minimisation.
The folding display stack
- 01 Scratch-resistant coating Top surface protection
- 02 Nano-textured cover Custom polymer, up to 40% higher stiffness than other industry materials
- 03 High-strength glass Structural, above the panel
- 04 Folding OLED panel The display itself
- 05 High-strength glass Structural, below the panel
- 06 Custom adhesives Let layers glide past one another like pages of a book, relieving bend stress
- 07 Titanium plate Bottom-most durability layer
The sliding-adhesive approach is the key idea: rather than forcing every layer to bend at the same radius, the layers shear against each other, reducing stress at the fold line.
WATER & DUST IP68
6 metres for up to 30 minutes (IEC 60529). Water ingress has historically been the weak point of any device with a moving seam; Galaxy Z Fold 8 does not match this, and the Pixel 10 Pro Fold is the only other foldable rated to IP68. Resistance is not permanent and liquid damage is not covered under warranty.
CERAMIC SHIELD 2 3×
Scratch resistance versus the previous generation, on the outer display. Apple has not stated how the inner polymer cover compares, and folding polymer covers are historically softer than glass.
REINFORCEMENT Support ribs. Ceramic-fibre antenna inserts.
Antenna splits are filled with ceramic fibre inserts to restore frame rigidity, solving the usual problem that antenna gaps weaken a frame.
05 · A20 Pro
The same 2 nm chip as iPhone 18 Pro, built to hold its pace.
No bespoke foldable silicon, no M-series. A20 Pro uses a new package inspired by M-series: the processor die sits side by side with memory instead of stacking in its thermal path. A custom vapour chamber connects directly to the chip. Apple claims the fastest CPU in a smartphone.
PROCESS 2 nm TSMC, down from 3 nm-class on A19 Pro
CPU +20% 6-core, up to 20% faster than A19 Pro; reported 2P + 4E
GPU +40% 7-core with Neural Accelerators, more power efficient
NEURAL ENGINE 2× Dual 16-core, twice the compute for on-device AI
MEMORY BANDWIDTH +50% Unified memory bandwidth
SUSTAINED +35% vs iPhone 17 Pro, via custom vapour chamber
SUSTAINED
Up to 35 percent better sustained performance than iPhone 17 Pro. Sustained is the operative word: peak performance is easy to reach and hard to hold, and holding it under load is where thin foldables usually fail.
DISPLAY ENGINE
A new display engine drives the inner and outer displays simultaneously and manages the transition as the device opens and closes. Most foldables switch between panels; Duo drives both.
RAM · UNCONFIRMED
Apple never publishes RAM figures. Third-party databases list 12GB, which matches the reported requirement for the full Siri AI feature set. Likely, but unconfirmed.
06 · Battery & charging
One cell each side, run as one.
A single large cell cannot span a hinge, so Duo carries a high-energy battery on each side. Apple silicon and energy-rebalancing algorithms coordinate charge and discharge so the pair behaves as one battery. Going eSIM-only frees internal volume that goes to capacity; Apple states this explicitly.
OUTER ONLY · VIDEO 44 h 37 h streamed
INNER ONLY · VIDEO 31 h 26 h streamed
TYPICAL MIXED USE 24 h
The figure to plan around, assuming equal time on both displays. iPhone 18 Pro is rated for 36 hours of video and the Pro Max for 45, so the Duo sits below both.
- Wired USB-C
- 50% in ~20 min
- MagSafe / Qi2 wireless
- 50% in ~30 min
- MagSafe / Qi2 peak
- Up to 25W
- Five-minute top-up
- Up to 5 h video on outer display
The 20-minute figure needs a 60W-or-higher USB-C adapter; wireless needs 35W or higher with a MagSafe Charger. No power adapter is in the box. For comparison, iPhone 18 Pro reaches 50 percent in about 15 minutes.
07 · Camera system
48MP Dual Fusion. Four cameras. No telephoto lens.
Two 48MP rear cameras, a 12MP Center Stage camera on the outer display and an under-display FaceTime camera inside. The “2× Telephoto” is an optical-quality crop from the main sensor, not a separate lens.

08 · Duo-exclusive
Five features that need the second screen.
Five features not possible on any other iPhone, plus a device that stands as its own tripod.
02
Rear-camera selfies
Take a selfie with the higher-resolution rear cameras while previewing the shot on the outer display, giving a self-portrait main-camera image quality.
03
Duo Preview
Shows the live preview on the outer display, facing your subject, so they can pose, check their own framing and guide the shot themselves.
04
Kid Cue
Plays animations from Peanuts on the outer display to hold a child's attention so they look towards the camera.
05
Duo FaceTime
People physically with you join the video call on the outer display, so everyone shares the moment without crowding one screen. Dual Capture shares front and rear feeds simultaneously.
09 · Video
4K Dolby Vision to 120 fps.
- 4K Dolby Vision
- 24, 25, 30, 60, 100 and 120 fps on Fusion Main

Audio Mix isolating music is a meaningful upgrade for anyone shooting at events or performances.
10 · iOS 27 on iPhone Duo
Controls move to the sides. Two apps share the screen.
Duo ships with iOS 27.1. Because the open device is wide, Lock Screen controls, the Dock and app navigation move to the sides to preserve vertical space. The status bar becomes a circular system nestled into a corner. Dynamic Island is redesigned to sit vertically along the side of both displays, still expanding for Live Activities.
Those side controls sit on the right, with no setting to move them across, and the dock takes four apps rather than the usual grid.
The transition between the two displays is the part that stands out. The outer screen lights the instant the device shuts, with none of the lag that is normal on a foldable, and opening dissolves whatever you were doing straight onto the larger panel.
SPLIT VIEW · A FIRST FOR IPHONE
- Two apps side by side; two windows of the same app (Safari, for comparison shopping)
- Quick swap; save pairs of apps to return to later
- Talk to Siri AI on one side while reading on the other
- Pin video to the top in portrait while using apps below
When open, the Home Screen shows two pages with Today View, a vertical list of widgets, on the left. The two Home Screens mirror each other: change the layout or add a page on one display and the other follows.
STANDBY · WITHOUT A CHARGER
Set Duo down and it enters StandBy on either display, even when not charging, closed or folded. Faces: Clock, Modular, Calendar (new), Weather (new), Photos (now with Shared Albums). Every face gains new colours, fonts and complications.
Posture-aware: content reacts as it folds, reorients when turned, switches display when flipped, and works partially folded in StandBy, landscape, portrait, seated and standing positions, including a laptop-like configuration.
Optimised at launch
- Netflix
- Scroll Clips on the outer display; open up for full screen
- Zoom
- Inner display becomes an immersive room: shared content and participants together
- Slack
- Brings the entire workspace into view at once
- Detail
- Uses the new Core AI framework, running models on-device for content creation
New and updated APIs in the latest SDKs; upcoming iPhone Duo support in Device Hub in Xcode; Apple's own apps optimised at launch. On the inner display, apps lay out like iPad apps, in multiple columns.
11 · Apple Intelligence & Siri AI
An entirely new Siri, in beta, not everywhere.
Siri AI rolls out in beta with iOS 27, powered by Apple Intelligence; reporting indicates it is Gemini-powered under the hood. It understands personal context across messages, mail and photos, acts on what is on screen, answers with broad world knowledge, writes anywhere you type, and keeps conversations in a dedicated Siri app synced privately via iCloud. On-device processing where possible; Private Cloud Compute for heavier work.
- Spatial Reframing
- Improve composition after capture
- Extend
- Extend image boundaries
- Clean Up
- Upgraded object removal
- Image Playground
- Now offers photorealistic imagery
- SynthID
- Identify AI-generated or edited images, in a later update
- Notify Me (Safari)
- Monitor pages for restocks and price drops
- Call Context (Phone)
- Surfaces confirmation and reservation numbers when you call a business
DATES
Apple Intelligence and Siri AI beta: Monday 14 September 2026 with iOS 27, English only. French, Japanese, Korean, Portuguese and Spanish follow in October 2026. Apple Intelligence itself supports 16 languages including German, Italian, Chinese and Japanese.
RESTRICTIONS
Siri AI is not available in the EU at launch on iOS, iPadOS or watchOS. Apple Intelligence is not available in China. Siri AI is not available to users under 13. For a device positioned around AI, that is a significant regional gap.
USAGE LIMITS
Siri AI, intelligent photo editing, Image Playground and AFM 3 Cloud models in Shortcuts are subject to daily usage limits that vary by feature and demand. Apple has stated expanded access will be available for a fee in the future: the first explicit signal that Apple Intelligence will be monetised beyond hardware.
12 · Connectivity, security & the rest
eSIM only, everywhere. Touch ID, not Face ID.
No SIM tray in any market, including regions where Apple previously kept one; the space goes to battery. eSIM is supported by over 500 carriers, including AT&T, T-Mobile and Verizon. Travellers who rely on local prepaid SIMs abroad will need to use travel eSIMs instead.
- iPhone Handoff
- Switch between two iPhones using the same phone number, on supported carriers
- N1 chip
- Wi-Fi 7, Bluetooth 6, Thread
- C2 modem
- Apple's next-generation modem: AI-powered reliability, mmWave in the US, reported ~50% faster and 15% more efficient than C1X
- Satellite
- Emergency SOS, Messages, Roadside Assistance, Find My. No satellite internet announced
- Video out
- AirPlay to 4K HDR; DisplayPort over USB-C or a Digital AV Adapter
SECURITY Touch ID in the side button
Face ID requires the TrueDepth camera stack, which needs more physical depth than a thin foldable can spare; the omission is attributed to internal space constraints. Side-button Touch ID works identically open or closed. Apple Watch unlock supported. Crash Detection, location sharing, Apple Pay, improved child safety in iOS 27.
APPLE PENCIL First iPhone with a stylus
Apple Pencil (USB-C) on both displays for notes, sketches and mark-up. Arrives later in 2026, not at launch. Samsung dropped S Pen support with the Z Fold 7.
ACCESSORIES Two first-party cases
iPhone Duo Case $79 (Sand, Navy Blue), Folio with Kickstand $129 (Navy Blue, Taupe). MagSafe, Qi2 25W, magnets aligned to the device. Both go on sale to order from 16 October.
AUDIO A speaker on each half
The top speaker fires from the front and the bottom one from the back, so opening the device puts one on either side of the fold for stereo. It is the best arrangement available to a foldable. Dolby Atmos playback.
IN THE BOX Device and a 1 m USB-C cable
No power adapter. Storage 256GB, 512GB, 1TB, 2TB. Ships with iOS 27.1.
Environmental profile
35% recycled content overall
100% recycled cobalt in the battery
100% recycled titanium in the hinge cover
60% renewable energy across the supply chain
100% fibre-based, home-recyclable packaging
13 · Pricing
From $1,999.
$800 above iPhone 18 Pro, $700 above 18 Pro Max, and only $100 above Galaxy Z Fold 8 in the US. Outside the US the premium over the Fold 8 is much larger: £300 in the UK, €340 in France, C$600 in Canada, A$800 in Australia. India is the most extreme gap.
For a first-generation foldable, in a category where $1,800 to $2,000 is the going rate, $1,999 lands lower than the run-up suggested it would.
MARKET
Pricing is not uniform across Europe: France and Germany differ by €40 at the base tier.

17 · What you give up
Nine trade-offs Apple named. And one it did not.
- 01 No dedicated telephoto
The 2× is a crop from the 48MP main sensor. Zoom tops out at a 4× optical-quality range and 10× digital. iPhone 18 Pro keeps a real telephoto.
- 02 No variable aperture
iPhone 18 Pro has a six-blade ƒ/1.48–ƒ/4 aperture with manual aperture and shutter controls. Duo is fixed at ƒ/1.6.
- 03 No Face ID
Touch ID works identically open or closed and Apple Watch unlock helps, but there are no attention-aware features and app authentication behaves differently.
- 04 No physical SIM, anywhere
Straightforward in most developed markets, but a real inconvenience for travellers who buy local prepaid SIMs.
- 05 Weight
At 254 g it is heavier than iPhone 18 Pro Max, and 53 g heavier than Galaxy Z Fold 8.
- 06 The five-week wait
It ships on 23 October, five weeks after iPhone 18 Pro, and supply is expected to be tight.
- 07 Battery below the Pros
Rated for 24 hours of mixed use, against 36 hours of video on iPhone 18 Pro and 45 on the Pro Max.
- 08 First-generation risk
This is a first-generation product built around a moving part, and no long-term durability data exists for it yet.
- 09 Siri AI unavailable in the EU
Apple Intelligence is also unavailable in China. For a device positioned around AI, that is a significant regional gap.
- 10 The under-display selfie camera
Hiding the camera keeps the inner display unbroken, but image quality is what pays for it: the footage it produces is visibly poor even in good light. The industry tried under-display cameras and moved back to cutouts for exactly this reason. A hole-punch and a better sensor would have been the smarter trade.

Treat any circulating figure as an estimateTeardowns and independent durability testing after the 23 October launch will fill most of these gaps.
- Hinge cycle rating
- Every competitor publishes one; Oppo claims 600,000 folds on the Find N6. Apple has published nothing.
- Crease measurement
- “Minimised”, never quantified. Oppo publishes a 0.05 mm surface variation figure.
- Battery capacity
- Never published. Third-party estimates near 4,700 mAh.
- RAM
- Never published. 12GB widely assumed.
- Inner display thickness
- Not published.
- Inner cover scratch resistance
- Apple compares the polymer's stiffness to industry norms, not its scratch resistance to glass.
19 · Who should buy it
iPhone Duo is not a flawless first attempt, but it has a great deal going for it. For anyone who wanted a foldable without leaving iOS, this is the first time that has been an option at all.
STRONG FIT
- Anyone who wants a tablet and a phone in one pocket
- Heavy multitaskers: Split View is new capability
- People who read, annotate or sketch: nano-texture plus Pencil
- Anyone deep in the Apple ecosystem, waiting seven years
- Video watchers: large matte display, Dolby Vision, strong battery figures
POOR FIT
- Zoom photographers
- Face ID dependants, especially for banking or work apps
- Frequent travellers who buy local physical SIMs
- Weight-sensitive buyers: 254 g is noticeable
- Anyone in the EU who wants Siri AI
- First-generation sceptics
CONSIDER WAITING IF
You can tolerate another year. A second-generation Duo would likely address the telephoto gap, possibly Face ID, and benefit from a year of real-world hinge data.
20 · Questions
Common questions.
What is the iPhone Duo?
Apple's first foldable iPhone: a tablet in your pocket.
How much does it cost?
From $1,999 for 256GB in the US, rising to $3,199 for 2TB.
When can I buy it?
Pre-orders open 16 October 2026 at 5 a.m. PT. It ships 23 October 2026.
Does it have Face ID?
No. It uses Touch ID built into the side button. You can also unlock it with an Apple Watch.
Does it have a telephoto lens?
No dedicated telephoto lens. The 2× telephoto is a crop from the 48MP main sensor.
Is there a SIM tray?
No. The Duo is eSIM-only in every market worldwide.
How big is the crease?
Hard to spot and very difficult to feel, thanks to the matte nano-texture finish. Not completely invisible, though.
How many times can the hinge fold?
Expect at least 200,000 folds — around 100 opens a day for five years, which is the current standard for the class. Oppo rates the Find N6 at 600,000.
Does it work with Apple Pencil?
Yes, Apple Pencil (USB-C), on both displays. Support arrives later in 2026, not at launch.
What colours does it come in?
Star White and Night Sky.
How heavy and how thin is it?
254 g, 5 g heavier than iPhone 18 Pro Max and 53 g heavier than Galaxy Z Fold 8. 5.2 mm open, 11.3 mm closed.
Is it waterproof?
IP68 rated, up to 6 metres for 30 minutes. Water resistance is not permanent and degrades with wear.
What chip and how much RAM?
The A20 Pro: a 2 nm chip with a 6-core CPU, a 7-core GPU and a dual 16-core Neural Engine — the same silicon as iPhone 18 Pro and Pro Max. RAM is expected to be 12GB, the amount the full Siri AI feature set requires.
How long does the battery last?
Up to 24 hours of typical mixed use. Up to 44 hours of video on the outer display alone, or 31 hours on the inner display.
Does it come with a charger?
No. The box has the phone and a 1-metre USB-C cable.
Can I run two apps at once?
Yes. Split View, a first for iPhone. You can also open two windows of the same app and save app pairs.
Is Siri AI available everywhere?
No. It launches in English only, in beta, on 14 September 2026, with more languages in October. It is not available in the EU at launch, and Apple Intelligence is not available in China.
Will there be enough stock at launch?
Probably not in the first few weeks. Folding display production is the bottleneck, and the five-week gap after iPhone 18 Pro points the same way. Order on 16 October, when pre-orders open at 5 a.m. PT, if you want one near launch.
Should I buy the first generation?
Apple's first-generation hardware tends to age well — the M1 MacBook Air is still an excellent machine years after launch. Duo is built on proven parts: the same A20 Pro as iPhone 18 Pro, a titanium frame and IP68 sealing. If the folding format suits how you use a phone, it is a sound buy.
