iPhone Duo release date: When will it go on sale?

Apple unveiled the iPhone Duo on September 9, 2026, but unlike the iPhone 18 Pro models it won’t arrive until October.

From Monday, October 12, Apple will let customers “Get Ready” for iPhone Duo pre-orders. Through the Apple Store app, buyers will be able to choose their preferred color and storage capacity, select a carrier, arrange a trade-in or financing, choose AppleCare+, and enter payment and delivery information in advance. That should make placing the final order considerably quicker once pre-orders open.

Pre-orders begin on Friday, October 16, at 1 p.m. in the U.K. and 5 a.m. Pacific in the U.S.

The iPhone Duo officially goes on sale one week later on Friday, October 23, in more than 70 countries and regions, including the U.S., U.K., Canada, Australia, China, France, Germany, India and Japan. A further 28 countries and regions will get it on October 30.

It will be available directly from Apple online and through Apple Stores, with carrier availability varying by market.

Initial supplies may be limited. A late-September supply-chain report claimed Apple and its manufacturing partners were still experiencing relatively low production yields for the new folding design.

iPhone Duo design: What does it look like?

Apple

The iPhone Duo uses a book-style folding design. Closed, it is unusually short and wide for an iPhone, measuring 84.1mm wide, 117.8mm tall and 11.3mm thick. Open it and the width expands to 164.6mm, while thickness reduces to just 5.2mm, making it Apple’s thinnest iPhone when unfolded (taking that mantle from the iPhone Air). It weighs 254g.

The outer screen measures 5.4 inches, while the folding inner panel measures 7.6 inches. Both are Super Retina XDR OLED displays with ProMotion up to 120Hz, Always-On display support and up to 3,000 nits outdoor peak brightness. The internal display also has a nano-texture surface designed to reduce reflections and make the crease less noticeable.

The frame and hinge cover are made from Grade 5 titanium. Apple uses a mirror-polished finish on the enclosure and a micro-blasted finish on the 3D-printed hinge cover. Ceramic Shield protects the rear, while Ceramic Shield 2 protects the outer display. The phone retains an IP68 rating despite its folding construction.

Apple

There are just two colors: Star White and Night Sky, essentially confirming the pre-event reports of silver/white and a very dark blue. For more information read about the iPhone Duo colors.

Action button and Camera Control

There is Camera Control, giving access to exposure, depth, zoom, cameras, styles and tone. It can also launch the new Siri Camera mode.

However, Apple’s Duo doesn’t feature an Action button. The regular iPhone 18 Pro and Pro Max retain both the Action button and Camera Control, so this is one hardware-control compromise of the folding model.

Accessories

Apple is also launching two dedicated accessories for the foldable:

• The iPhone Duo Case at $79/£79
• The Duo Folio with Kickstand at $129/£129

Both will be orderable from October 16.

Face ID, Touch ID and the notch

Perhaps the most surprising difference between the iPhone Duo and Apple’s other flagship iPhones is that there is no Face ID.

Instead, Apple has brought back Touch ID, with the fingerprint sensor incorporated into the side button. It works whether the Duo is folded or unfolded, and Apple Watch can also be used to unlock the device. This confirms one of the most persistent pre-launch rumors.

The internal display therefore does not need the TrueDepth sensors used for Face ID. Its FaceTime camera sits beneath the display and disappears when it isn’t being used, giving the inner screen a largely uninterrupted surface.

The inner camera itself is hidden below the display rather than sitting permanently in a visible camera cutout. And yet, despite this and the absence of Face ID, there is still support for Dynamic Island.

The biggest camera features for iPhone Duo

Duo Preview

The outer screen can show a live preview while somebody else is being photographed, allowing the subject to adjust their pose and framing.

Smart Take and Kid Cue

Smart Take detects when everybody is ready and automatically captures the shot. Kid Cue uses animations on the outer screen to encourage children to look towards the camera.

Two-screen shooting

The folding design supports unusual shooting configurations, including using the main cameras for selfies or group photos while seeing the composition on the other screen. Duo FaceTime can also put nearby participants onto the outer display.

Other notable camera features include 48MP macro photography, a 2x optical-quality crop from the Main camera, an under-display inner FaceTime camera, Dual Capture for simultaneous front-and-rear video, and 4K Dolby Vision recording at up to 120fps.

Rear cameras

The 48MP Fusion Main has an f/1.6 aperture, sensor-shift stabilization and can shoot 24MP or 48MP images. It also provides a 12MP, 2x optical-quality crop equivalent to a 52mm lens.

The 48MP Fusion Ultra Wide has a 13mm-equivalent lens, f/2.2 aperture and 120-degree field of view. It also supports 48MP macro photography and is the same Ultra Wide camera used by the iPhone 18 Pro family.

That means the Duo does not match the iPhone 18 Pro and Pro Max camera system. Those phones add a dedicated 48MP Fusion Telephoto and variable aperture on the Main camera, making the Pro models much more flexible for photography despite costing substantially less.

Pre-event reports were divided between a Main + Telephoto and Main + Ultra Wide arrangement. Apple ultimately chose Main + Ultra Wide, confirming the earlier reports that a dedicated telephoto could be sacrificed to save space.

Front cameras

On the outside is a 12MP Center Stage camera with an f/2.2 aperture. It supports Center Stage, automatic portrait/landscape framing, Dual Capture, Photonic Engine, Deep Fusion, Smart HDR 5 and 4K Dolby Vision video at up to 60fps.

Inside is an under-display FaceTime camera with an f/1.8 aperture. Apple does not specify its megapixel resolution. It supports Center Stage for video calls and records at up to 1080p/60fps. Its major advantage is visual rather than photographic: the camera effectively disappears beneath the display when it isn’t being used.

iPhone Duo video features

The Main camera records 4K Dolby Vision at 24, 25, 30, 60, 100 or 120fps, with 4K/120fps also available for slo-mo. Cinematic mode reaches 4K/60fps and Action mode up to 2.8K/60fps. Dual Capture can record at up to 4K/30fps.

Apple’s specifications also do not list ProRes or Apple Log recording for the Duo. Those remain more Pro-oriented capabilities rather than part of Apple’s foldable camera proposition.

The Duo does support Spatial Audio recording, Audio Mix, Dolby Vision HDR and Apple’s computational photography features including Photonic Engine, Deep Fusion, Smart HDR 5, Photographic Styles 3, smart focus tracking and Apple Intelligence-powered editing.

Apple does not list conventional Spatial Video capture in the Duo specifications.

iPhone Duo processor: What processor does it use?

Apple

The iPhone Duo uses the A20 Pro, the same processor as the iPhone 18 Pro and Pro Max.

It is manufactured using a 2-nanometer process, a major step forward in transistor density and efficiency. Apple combines it with a new chip packaging design inspired by its M-series Mac processors. The package connects the A20 Pro directly to a custom vapor chamber to transfer heat away from the processor more effectively.

The A20 Pro includes:

• 6-core CPU: two super cores and four efficiency cores
• 7-core GPU with Neural Accelerators
• Dual 16-core Neural Engine
• Hardware-accelerated ray tracing
• A dedicated display engine capable of operating both Duo displays

Compared with the A19 Pro, Apple says the CPU is up to 20 percent faster, while the GPU is up to 40 percent faster and more power-efficient. The Dual 16-core Neural Engine delivers twice the compute power, while unified-memory bandwidth rises by 50 percent.

Apple also claims that the complete thermal system gives the Duo up to 35 percent better sustained performance than the iPhone 17 Pro. That sustained-performance figure is particularly important for a folding device because prolonged gaming, multitasking and AI workloads generate considerably more heat than short benchmark bursts.

iPhone Duo RAM: How much memory does it have?

Apple has not disclosed how much RAM is inside the iPhone Duo.

Before launch, supply-chain reports consistently pointed to 12GB of RAM, which would make sense given the demands of running two displays, simultaneous applications, Siri AI and larger on-device AI models.

Apple does reveal that A20 Pro has 50 percent more unified-memory bandwidth than A19 Pro, which should help the Duo move data more quickly between the CPU, GPU and Neural Engine.

Extra memory is particularly useful on the Duo because iOS 27.1 can display multiple apps simultaneously and because Apple Intelligence and Siri AI increasingly run generative models locally rather than relying entirely on cloud processing.

iPhone Duo connectivity

Apple

Apple has put a significant amount of its own communications silicon into the iPhone Duo.

It uses Apple’s new C2 cellular modem, replacing Qualcomm silicon. Apple says C2 introduces AI-powered improvements to cellular quality and reliability and supports mmWave 5G in the U.S.

The N1 wireless networking chip provides:

• Wi-Fi 7 with 2×2 MIMO
• Bluetooth 6
• Thread networking

The USB-C port also supports USB 3 data transfers at up to 10Gbps and DisplayPort video output.

The Duo also has Apple’s second-generation Ultra Wideband chip, NFC and precision dual-frequency GPS.

It is eSIM-only worldwide, something that had been widely rumored before launch. Eliminating the SIM tray gives Apple additional internal space for its batteries.

Satellite capabilities include:

• Emergency SOS via satellite
• Roadside Assistance via satellite
• Find My via satellite
• Messages via satellite

Battery, MagSafe and charging: What’s available?

Instead of one battery spanning the body, the iPhone Duo contains two rechargeable lithium-ion batteries, with one high-energy battery fitted into each half of the device. Apple’s energy-balancing algorithms make them operate as a single battery system.

Apple rates battery life at:

• Up to 24 hours of typical use
• Up to 44 hours video playback using the outer display
• Up to 31 hours using the inner display
• Up to 37 hours streamed video on the outer screen
• Up to 26 hours streamed video on the inner display

Apple has not disclosed the batteries’ combined capacity in mAh. The pre-launch rumor of approximately 5,000-5,500mAh therefore remains unconfirmed.

Wired charging can take the Duo to 50 percent in around 20 minutes with a 60W-or-higher USB-C adapter.

Despite earlier uncertainty, MagSafe is supported, with wireless charging at up to 25W. Qi2 charging also reaches 25W. Apple says a 35W-or-higher adapter and MagSafe charger can bring the battery to around 50 percent in approximately 30 minutes.

iPhone Duo vs iPhone 18 Pro pricing

The iPhone 18 Pro starts at $1,199/£1,199, while the iPhone 18 Pro Max starts at $1,299/£1,299. That makes the Duo approximately $700/£700 more expensive than the Pro Max at entry level.

That premium buys the folding display, precision hinge, titanium structure, second screen and more complex dual-battery design rather than superior cameras: in several areas the iPhone 18 Pro models are actually better equipped.

Reports before the launch suggested the Duo could cost anywhere from around $1,999 to $2,399 at entry level, largely because of the folding OLED display, hinge mechanism, titanium components and other expensive parts. Apple ultimately landed at the very bottom of those predictions.

Should you buy the iPhone Duo?

The iPhone Duo is the iPhone to buy if you genuinely want a phone and small tablet in one device. Its 7.6-inch display, multitasking features, A20 Pro performance and clever fold-specific camera modes offer capabilities no other iPhone has. 

But at $1,999/£1,999 it is enormously expensive, and there are significant compromises: no Face ID, no dedicated telephoto camera, no variable aperture and no Action button. 

For photography, battery life and conventional everyday use, the iPhone 18 Pro Max is likely to be the better-value flagship. Buy the Duo because you want the folding experience, not because it is simply the “best” iPhone.

When is Apple’s next event?

• Next rumored product launch: October 13, 2026. An event remains unconfirmed.

Bloomberg’s Mark Gurman has claimed on X that Apple will launch its “next big thing” on October 13, referring to new smart-home products. Apple has not confirmed the date, and it remains unclear whether the company will hold an event or announce the products through its website and press releases.

Apple hasn’t announced a date for another event in 2026, but it is possible that more new products will launch at an event, or via press release, before the end of the year.

Apple has held October events in the past: in 2023, an event was held on October 30, while in 2021 Apple held one on October 18. With the iPhone Duo launching on October 22, Apple may want to avoid clashing with that launch, making the following week, beginning October 26, a plausible window for another event or product announcements.

What could Apple launch at the next event?

The rumored lineup centers on Apple’s first smart-home display, often called HomePad. Gurman describes a 6-inch screen mounted above a speaker base on a manually tilting arm, plus a separate wall-mounted version. Updated HomePod mini and Apple TV 4K models with faster processors are also expected.

Other rumored launches include new iPads and a touchscreen MacBook Pro, but this report does not establish that they will arrive alongside the smart-home products.

Will Apple have a second fall event in 2026?

Apple

Will there be a late fall event in 2026?

The latest reporting points to a smart-home launch on October 13, although its presentation format remains unclear. Apple could announce these products without holding a keynote.

The last time Apple held a late fall event was on October 30, 2023, and before that on October 18, 2021. So while a late fall event would not be unprecedented, it has become relatively uncommon.

Right now, there is no way of knowing whether Apple will hold another event in late 2026, or whether it will continue to launch new products through press releases instead. In the past, October events have often focused on Macs, but in recent years Apple has shown that it does not always consider a dedicated event necessary for Mac launches.

What could Apple launch at the late fall 2026 event?

Apple’s next launch could focus on smart-home products, including the rumored HomePad display, an updated HomePod mini and a new Apple TV 4K. The latter two are expected to feature faster processors that could support Siri AI features.

Other possible launches before the end of the year include the rumored touchscreen MacBook Pro and updates to the iPad and iPad mini. However, it remains unclear whether Apple would announce these alongside its smart-home products, hold a separate event or introduce them through press releases.

Will Apple hold a spring event in 2027?

Michael Simon / Foundry

Apple’s spring events have become increasingly unpredictable. The company has not held a traditional spring event since May 2024, although it did invite members of the media, including Macworld, to a “Special Apple Experience” in 2026.

Rather than a keynote presentation, the March 4, 2026 gathering was a hands-on showcase that followed three days of product announcements, including the MacBook Neo, iPhone 17e, and M5 MacBook Air.

Will Apple take a similar approach to spring product launches in 2027? It’s certainly possible. The format appeared to work well, allowing each product announcement to receive its own media coverage rather than competing for attention during a single event.

Apple is expected to release three iPhone models in spring 2027 – or it could be two new iPhones, with the Air and iPhone 18 merging.

• iPhone 18 (base model)
• iPhone 18e
• iPhone Air 2

Apple may also update the MacBook Air with an M6 processor in spring 2027.

When is WWDC 2027?

Foundry

When is the WWDC keynote?

In 2026 the WWDC keynote was on Monday June 8. In 2025 it started on Monday June 9. We expect WWDC will start on Monday 7 June in 2027.

WWDC generally runs from the Monday to Friday in the second week of June.

What Apple could launch at WWDC

WWDC is Apple’s big developer event at which it reveals plans for the operating systems that run on Apple hardware.

In June 2027 we expect Apple to unveil details of iOS 28, iPadOS 28, macOS 28, updates to watchOS, tvOS, HomePod software, and an update to Apple’s realityOS.

Apple sometimes announces new hardware at WWDC, usually the high-end models targeted at power users, so we could see new Macs.

Following the keynote on Monday, developer events and sessions will run throughout the week. You can read more about WWDC date, times and everything you need to know in a separate article.

What did Apple launch at past events?

So far in 2026 Apple has held an ‘experience’, which rather than being an event in the traditional sense, was a chance for journalists to get a look at products Apple had launched in the days prior, including MacBook Neo and iPhone 17e. The company also hosted the WWDC keynote on June 8, at which it revealed its plans for Apple Intelligence and Siri in iOS 27, macOS 27 and the other operating systems. Plus Apple held its iPhone launch event on September 9 at which the iPhone 18 Pro and Max, iPhone Duo, Apple Watch Series 12, Apple Watch Ultra 4 and AirPods 5 launched.

In 2025 Apple only held two events. The first was its Worldwide Developers Conference (WWDC) on June 9, at which it introduced the new features coming in the next version of its operating systems, and the second was the huge September 9 Apple Event where it launched new Apple Watches, new AirPods Pro and the new iPhones for 2025.

Apple doesn’t have to hold an event to launch new products though. Prior to WWDC, Apple launched a new iPhone 16e via press release on February 19, a new iPad and iPad Air via press release on March 4, and a new MacBook Air and Mac Studio on March 5.

Apple then went on to launch a new M5 MacBook Pro and M5 iPad Pro in October. No event was held to mark these launches.

In 2024, Apple held three events: one on Tuesday, May 7, at which it launched new iPads; a keynote to kick off WWDC on June 10; and an event on September 9 at which Apple unveiled the new iPhone 16, Apple Watch Series 10 and the AirPods 4. In October 2024 there was no event, but Apple did announce new products (iMac, Mac mini and MacBook Pro) via press release.

In 2023 there were three events: WWDC in June, an iPhone event in September, and Apple’s second fall event on October 30 (or after midnight on October 31 if you weren’t in the U.S.).

In 2022 Apple held three events: a spring event on March 8, WWDC on June 6, and the iPhone 14 launch on September 7. In other years Apple has held four events though.
