**Apple** has entered the foldable market with the **iPhone Duo**, a book-style device that opens to a 7.6-inch Super Retina XDR display and starts at $1,999\. The phone headlined the company's "Surprise and Shine" event in Cupertino, the first major hardware launch under chief executive John Ternus. Apple used the same stage to introduce the iPhone 18 Pro and iPhone 18 Pro Max, both built around a 2-nanometre **A20 Pro** chip that also powers the foldable.

Closed, the iPhone Duo shows a 5.4-inch outer Super Retina XDR panel that carries 90% of the screen area of an iPhone 18 Pro. Opened, that inner 7.6-inch screen is 80% larger than the 18 Pro's display and is the largest Apple has shipped on an iPhone. The company says the device is its thinnest phone when unfolded, and it can also be used partially folded, a position that keeps the outer screen active while the hinge holds the frame at an angle.

## iPhone Duo specs and hardware

Both panels use ProMotion and reach up to 3,000 nits of peak brightness, with a nano-texture finish available on the inner display. The frame is grade 5 titanium, paired with a hinge built from more than 100 parts, Ceramic Shield 2 glass, and an IP68 water and dust rating. Buyers can pick Star White or Night Sky, a dark blue.

Inside, the A20 Pro pairs a 6-core CPU with a 7-core GPU and a 16-core Neural Engine. A custom vapor chamber and a dual-battery layout, with one cell on each side of the hinge, push video playback to a claimed 31 hours on the inner display and 44 hours on the outer screen, alongside 24 hours of mixed use. Apple says the combination delivers 35% higher sustained performance than the iPhone 17 Pro. A new Apple-designed C2 modem handles cellular connectivity, continuing the company's shift away from Qualcomm components.

| Model             | Starting price  | Display                | Chip    | Pre-orders | On sale |
| ----------------- | --------------- | ---------------------- | ------- | ---------- | ------- |
| iPhone Duo        | $1,999 / £1,999 | 5.4" outer, 7.6" inner | A20 Pro | Oct 16     | Oct 23  |
| iPhone 18 Pro     | $1,199          | n/a                    | A20 Pro | Sept 12    | Sept 18 |
| iPhone 18 Pro Max | $1,299          | n/a                    | A20 Pro | Sept 12    | Sept 18 |

Cameras on the iPhone Duo include a 48MP Fusion Main sensor and a 48MP Ultra Wide, with 4K video capture at up to 120 frames per second. An under-display FaceTime camera and a Center Stage front camera handle video calls, a configuration Apple has not used on a phone before.

Software support comes from iOS 27, which adds Split View multitasking so two apps can run side by side on the inner screen. Apple Intelligence and a rebuilt Siri with AI features ship on the device, and that Siri work draws on technology from Google's Gemini models. Apple Pencil support through the USB-C model is planned for later in the year, the first time the accessory works with an iPhone. The phone is eSIM-only and supports Wi-Fi 7 and Bluetooth 6, with storage from 256GB to 2TB.

The hinge assembly and titanium body answer the durability question that has trailed folding phones since the first models reached shelves. Ceramic Shield 2 on the exterior and the IP68 rating put the iPhone Duo on the same water-resistance footing as Apple's flat phones, and the nano-texture layer targets reflections on a surface owners will look at far more often than a standard phone screen. Whether the crease stays invisible after months of folding is the test no spec sheet can settle.

## iPhone Duo pricing and availability

Pre-orders for the iPhone Duo open on Friday, October 16, with retail availability on Friday, October 23 in more than 70 countries and regions. Additional markets follow on October 30\. The 256GB model starts at $1,999 in the United States and £1,999 in the UK, where Apple quotes £66.63 per month over 24 months. The 2TB configuration reaches $3,199, and regional pricing includes roughly ₹3 lakh in India and S$3,099 in Singapore. A Duo Case costs £79, and a Duo Folio £129.

That entry price sits $800 above the iPhone 18 Pro, which starts at $1,199, with the Pro Max at $1,299\. Apple's Pro phones open for pre-order on Saturday, September 12 at 5 a.m. Pacific Time and launch on September 18, with some markets limiting customers to two units of each model. Lease options run through Apple Upgrade, and the top 2TB iPhone Duo costs $1,200 more than the base model, before accessories are added.

The Pro line brings a variable aperture camera with four adjustable settings, a first for an iPhone, plus a redesigned display cutout. Apple also refreshed its wearables and audio range at the same event, announcing the Apple Watch Series 12, Apple Watch Ultra 4 and AirPods 5, all available for pre-order.

The foldable arrives with iOS 27.1 preinstalled, a point release that follows the iOS 27 build the Pro phones carry at their September debut. That staggered software timing splits the launch for developers, who get the Split View multitasking APIs with the Pro hardware in September but the folding form factor itself in October.

Competitively, the iPhone Duo lands against the Samsung Galaxy Z Fold 8, the device that has defined the book-style category. Apple arrives years after rivals began shipping folding phones, and it prices above its own Pro tier rather than replacing it, opening a new revenue line at the top of the lineup. Comparisons will turn on hinge feel, crease visibility and how third-party apps behave on a 7.6-inch inner screen.

## Why this matters

The iPhone Duo tests whether Apple can charge a premium for a form factor rivals have sold for years, and it creates a new top tier above the Pro line instead of replacing it. For buyers, the decision is now three-way: a $1,199 iPhone 18 Pro with the same A20 Pro chip, a $1,299 Pro Max, or a $1,999 foldable with a larger screen and a five-week-later ship date. How Apple holds that price gap through the October launch window will set the ceiling for every flagship that follows it.
