)
)
Apple has unveiled the iPhone Duo, the company’s first foldable iPhone. The new model combines a compact phone with a larger, tablet-like display and represents one of the biggest changes to the iPhone’s design in years.
Short answer: The iPhone Duo is Apple’s first foldable phone. When closed, the outer display works like the screen on a conventional iPhone. Open it to access a larger display designed for multitasking, video, reading and work. Pre-orders begin on 16 October, followed by the official release on 23 October 2026.
What Is the iPhone Duo?
The iPhone Duo is a foldable iPhone that opens like a book. The name Duo refers to the model’s ability to work both as a conventional phone and as a smaller tablet.
When closed, the phone can be used for everyday activities such as messages, calls, photography and notifications. When opened, it provides a much larger workspace with room for multiple apps and more content.
Before it was unveiled, the model was also referred to as the iPhone Fold and iPhone Ultra. Its official name is iPhone Duo.
How Large Is the iPhone Duo’s Display?
The iPhone Duo has a 5.4-inch outer display and a 7.6-inch foldable inner display. The larger screen allows the phone to be used in a way that resembles a small iPad.
The foldable design is suitable for:
using two apps side by side
reading emails and documents
watching films and videos
making video calls
editing photos and other content
switching between phone and tablet modes
The interface automatically adapts depending on whether the phone is open or closed.
What Features Does the iPhone Duo Have?
The iPhone Duo is powered by the A20 Pro chip and runs iOS 27, which has been adapted for its foldable screen. Apps, controls and menus can move and change size depending on how the phone is being used.
Key features include:
a foldable OLED display
an outer display for use when the phone is closed
the A20 Pro chip
multitasking with multiple apps
Apple Pencil support
two rear cameras
Touch ID integrated into the side button
a new hinge that allows the phone to lie flat when opened
The phone can also be used at different angles, such as during video calls or when watching content without holding the device.
When Is the iPhone Duo Available?
Pre-orders for the iPhone Duo begin on 16 October 2026. The phone officially goes on sale, with the first deliveries arriving, on 23 October.
Availability and delivery dates may vary between markets. As this is Apple’s first foldable phone, the number of devices available at launch may be limited.
How Much Does the iPhone Duo Cost?
The iPhone Duo has a starting price of approximately $1,999 for the model with 256 GB of storage. This makes it one of the most expensive iPhone models Apple has released.
Local pricing may vary depending on taxes, exchange rates and the storage capacity you choose.
Which Case Fits the iPhone Duo?
The iPhone Duo needs a phone case specifically designed for its foldable construction. A conventional iPhone case will not fit because the Duo has two sections and a hinge that must be able to open and close freely.
An iPhone Duo case should:
protect the front and back of the phone
be designed around the hinge
avoid restricting the folding mechanism
have the correct openings for the cameras, buttons and charging
remain secure when the phone is both open and closed
Always check that a case is specifically listed as compatible with the iPhone Duo before ordering.
