iPhone Duo: Apple Unveils Its First Foldable iPhone at $1,999 — Release Date, Price, Size and Features

The iPhone Duo is officially here. Apple has unveiled its first foldable iPhone, ending years of speculation about when the company would enter the growing foldable-phone market.

The new Apple Duo was introduced at Apple's September 2026 event alongside the iPhone 18 Pro and iPhone 18 Pro Max. The device uses a passport-style design that opens to reveal a much larger 7.6-inch display, while a 5.4-inch screen remains available when the phone is closed. Watch Full Video Here

The iPhone Duo release date is October 23, 2026, with preorders beginning October 16. Apple has set the starting iPhone Duo price at $1,999 in the United States for the 256GB model, making it the most expensive iPhone in Apple's current lineup.

iPhone Duo Price and Release Date

The iPhone Duo cost starts at $1,999 in the U.S. for 256GB of storage. Apple will also offer 512GB, 1TB and 2TB configurations.

For shoppers searching for the iPhone Duo release date, the important dates are:

• Announcement: September 9, 2026
• Preorders: October 16, 2026
• Release: October 23, 2026
• Starting price: $1,999
• Base storage: 256GB

Apple's decision to price the Apple foldable phone below some of the highest-priced competing foldables could help it attract buyers who have been waiting for an iPhone version of the form factor.

Apple Duo Has a Passport-Shaped Foldable Design

The most noticeable feature of the iPhone Duo is its design.

When closed, the Apple Duo phone resembles a compact passport or small booklet. It has a 5.4-inch outer display that allows users to use the device without opening it.

Opening the folding iPhone reveals a 7.6-inch inner display, the largest screen Apple has ever put into an iPhone. Apple says the two displays share the same aspect ratio, allowing content to transition more naturally between the folded and unfolded states.

That means the iPhone Duo size sits between a conventional smartphone and a small tablet when fully opened.

Apple has also made the device exceptionally thin when unfolded, positioning the Apple foldable iPhone as a major design change rather than simply a larger version of an existing iPhone.

Does iPhone Duo Have MagSafe?

One of the questions surrounding the new device is: does iPhone Duo have MagSafe?

Apple's launch materials emphasize the Duo's new hardware design, dual-battery architecture and wireless connectivity. Third-party launch coverage also reports support for MagSafe and Qi2 accessories, meaning buyers looking for iPhone Duo MagSafe compatibility should have access to Apple's magnetic accessory ecosystem.

Apple is also introducing accessories designed specifically for the foldable model, including a protective case and a small kickstand.

The iPhone Duo case is particularly important because protecting a foldable device requires a different approach from protecting a traditional iPhone.

iPhone Duo Crease: How Apple Tackled the Foldable Screen Problem

The screen crease has been one of the biggest criticisms of foldable smartphones.

Apple says it designed a specialized hinge and display construction to produce a smoother unfolded surface. The inner display uses a special nano-texture finish designed to reduce glare, while Apple's engineering is intended to make the transition between the folded and unfolded positions feel seamless.

That makes the iPhone Duo crease an important part of the company's pitch.

Apple is clearly trying to avoid the impression that the iPhone foldable is simply two conventional phones connected by a hinge. CEO John Ternus presented the Duo as a fundamentally different iPhone experience.

iPhone Duo Dimensions and Display

The iPhone Duo dimensions are built around its book-style folding design.

The outer screen measures 5.4 inches, while the unfolded interior display measures 7.6 inches. Both displays support ProMotion, Always-On Display and brightness of up to 3,000 nits, according to launch coverage.

Apple says the inner screen provides a larger canvas for gaming, watching video and multitasking.

The larger display also allows the Apple Duo to function more like a small tablet when opened, potentially reducing the need to carry both an iPhone and an iPad for certain tasks.

Apple Duo Performance and A20 Pro Chip

The Apple foldable phone is powered by Apple's new A20 Pro chip.

The chip is also used in the iPhone 18 Pro lineup and is designed to provide high performance while supporting Apple's latest AI features.

The Duo includes an advanced thermal-management system and a dual-battery architecture. Apple says the design delivers all-day battery performance despite the phone's thin profile.

The phone also uses Apple's new C2 cellular modem system and N1 wireless networking chip, bringing Wi-Fi 7, Bluetooth 6 and Thread connectivity.

iPhone Duo Camera Features

The iPhone Duo also receives a redesigned camera system built around Apple's foldable form factor.

The phone includes two 48MP rear cameras, while the folding design creates new ways to position the device for photography and video recording. Apple says the Duo can effectively turn into a personal photographer by using the device's screens and cameras in different configurations.

The camera system does not match the full camera setup of the iPhone 18 Pro Max, but Apple is emphasizing versatility rather than simply maximizing the number of lenses.

iPhone Duo Colors

Apple is keeping the first-generation foldable relatively simple when it comes to colors.

The iPhone Duo colors are:

• Star White
• Night Sky

The phone uses a Grade 5 titanium frame with a polished finish.

That means consumers searching for new iPhone colors will find a much smaller selection on the Duo than on the iPhone 18 Pro lineup.

iPhone 18 Pro and iPhone 18 Pro Max Also Debut

The iPhone Duo wasn't the only major announcement at Apple's September event.

Apple also introduced the iPhone 18 Pro and iPhone 18 Pro Max, with the Pro models receiving major camera, battery and performance upgrades.

The iPhone 18 Pro price starts at $1,199, while the iPhone 18 Pro Max price starts at $1,299. Both models are available for preorder September 12 and launch September 18.

The iPhone 18 Pro Max features Apple's new 48MP Fusion Main camera with variable aperture, a smaller Dynamic Island and the A20 Pro chip.

iPhone 18 Pro Max Colors

Apple is offering four finishes for the new Pro models:

• Black
• Silver
• Glacier
• Burgundy

The new burgundy iPhone 18 Pro Max is one of the biggest visual changes to Apple's Pro lineup, while glacier provides another new option for customers searching for iPhone 18 Pro colors.

For shoppers comparing the iPhone 18 Pro Max vs 17 Pro Max, the new model focuses heavily on camera flexibility, battery life, AI capabilities and sustained performance.

What Happened to the Regular iPhone 18?

Another important part of the Apple announcement is what wasn't introduced.

Apple's September event focused on the iPhone 18 Pro and Pro Max, while reports indicate the standard iPhone 18 is expected on a different timetable.

That means people searching when does iPhone 18 come out, iPhone 18 price or iPhone 18 pre order should distinguish the regular iPhone 18 from the newly announced Pro models.

The September launch is primarily about the premium iPhone lineup and Apple's new foldable.

iOS 27 Brings New Features to the iPhone Duo

The iPhone Duo launches with iOS 27, which Apple has redesigned to take advantage of the foldable display.

The software allows the large internal screen to support multitasking and different layouts while maintaining a familiar iPhone experience.

iOS 27 will become available as a free software update on September 14, 2026. Apple's new Siri AI features are also being introduced with iOS 27, bringing more contextual understanding to Apple's voice assistant.

The software is particularly important for the Apple Duo because Apple's success in the foldable market will depend not only on its hardware but also on how useful the larger screen becomes.

Apple CEO John Ternus Leads Major Apple Launch

The iPhone Duo launch also represents a major moment for Apple leadership.

John Ternus is making his first major product-event appearance as Apple's CEO after succeeding Tim Cook.

Ternus introduced the foldable iPhone as one of the company's biggest changes to the iPhone experience and positioned the Duo as a new category for Apple.

Tim Cook remains involved with the company as Apple's board chairman, while Ternus takes responsibility for Apple's product strategy as CEO.

Apple Stock Reacts to the iPhone Duo Launch

The launch is also being watched closely by investors tracking Apple stock, AAPL stock and the company's long-term growth strategy.

The iPhone remains Apple's most important hardware product, making the company's move into foldables significant for investors.

Apple shares were trading lower after the event according to live-event coverage, although the immediate stock reaction does not necessarily indicate how successful the Duo will become over the longer term.

The bigger question for AAPL stock is whether the Duo can create a new premium category while continuing to drive upgrades across Apple's conventional iPhone lineup.

Apple Foldable Phone Could Change the iPhone Market

The iPhone Duo marks Apple's official entry into a market dominated for years by companies such as Samsung and other Android manufacturers.

Apple waited considerably longer than its competitors to release a foldable phone. Instead of being first, the company appears to be betting that it can improve the design, software integration and durability of the category.

That strategy could make the Apple foldable phone one of the most important new products in Apple's recent history.

The $1,999 starting price is undeniably high, but Apple's huge installed iPhone user base gives the Apple foldable iPhone an audience that many competitors cannot match.

When Is the iPhone Duo Coming Out?

For anyone asking when is the Apple release or when is the iPhone Duo coming out, the answer is now official.

The iPhone Duo release date is October 23, 2026, with preorders opening October 16.

Apple's first foldable iPhone starts at $1,999, comes with 256GB of storage and is available in Star White and Night Sky.

The launch makes 2026 a particularly important year for Apple, with the company introducing its first foldable phone, the iPhone 18 Pro lineup, iOS 27, new AirPods and updated Apple Watch models.

For consumers who have been waiting for a folding iPhone, the wait is finally over. The iPhone Duo is no longer an Apple rumor or concept — it is Apple's first official foldable phone and one of the company's biggest new product launches in years.
