After years of rumours, Apple unveils its first foldable iPhone: the iPhone Duo. With its 7.6-inch display, compact format when folded and redesigned iOS experience, it introduces a new way to use an iPhone.

Discover the new features, price and availability of the iPhone Duo.

iPhone Duo: the main new features

The iPhone Duo stands out above all for its foldable design. When folded, it features a 5.4-inch display. Once unfolded, the screen reaches 7.6 inches.

Apple has also redesigned the iOS experience for this new format, including one-handed use, multitasking and a new tabletop mode.

Here are the main new features of the iPhone Duo:

• foldable 7.6-inch display;

• 5.4-inch display when the smartphone is folded;

• just 5.2 mm thick when unfolded;

• A20 Pro chip;

• Apple C2 modem;

• 100% titanium frame;

• 12 MP under-display front camera;

• two 48 MP rear cameras;

• Apple Pencil via USB-C compatibility;

• MagSafe compatibility;

• return of Touch ID on the side;

• two batteries providing up to one day of battery life.

A 7.6-inch foldable display

This is the most visible new feature of the iPhone Duo.

When folded, the smartphone has a 5.4-inch display. When unfolded, it reveals a 7.6-inch display.

Apple has adopted a “passport” format that keeps the smartphone compact in your hand while providing a larger display area when the device is opened.

An anti-reflective coating to reduce the appearance of the crease

Apple has paid particular attention to the inner display.

The 7.6-inch panel features an anti-reflective coating designed to improve readability and make the crease much less noticeable.

Apple explains that the display uses a multi-layer construction, including a thin titanium sheet underneath the panel. During the first hands-on experiences reported in the reference document, the crease was particularly difficult to see.

An iPhone just 5.2 mm thick

When completely unfolded, the iPhone Duo measures just 5.2 mm thick.

Its frame is made from titanium, while the smartphone features Ceramic Shield on both the front and back.

This slim design allows Apple to maintain a particularly compact format when the phone is used unfolded.

An under-display front camera

The iPhone Duo features an under-display front camera.

When it is not being used, the camera remains hidden behind the display. It becomes visible when you use features such as FaceTime.

This design allows the foldable display to retain its full surface without adding a visible camera cutout.

The front camera has a resolution of 12 MP.

iOS redesigned for the iPhone Duo

The iPhone Duo is not simply about offering a larger screen. Apple has also adapted iOS to its foldable format.

The interface moves elements such as the status bar and dock to the side of the screen. The goal is to keep the main controls within easy reach of your thumb when using the smartphone with one hand.

Multitasking also benefits from the 7.6-inch display.

Two apps side by side

Once the iPhone Duo is open, you can display two apps side by side.

An app can be moved to the left or right side of the screen to organise your workspace.

This allows you to switch from a traditional iPhone experience to an experience closer to that of a tablet.

Tabletop mode

The iPhone Duo also features a tabletop mode.

The smartphone can be partially folded, like a small laptop. The app can then use both sections of the display to provide an interface adapted to this position.

Two 48 MP cameras

The iPhone Duo features two rear cameras:

• a 48 MP main camera;

• a 48 MP ultra-wide camera.

The front camera has a resolution of 12 MP.

However, the camera system does not include all the features available on the iPhone 18 Pro models. The iPhone Duo does not include variable aperture, Pro mode or the new cinematic effects introduced on the Pro models.

Duo Camera

Apple introduces a feature called Duo Camera.

It allows you to use the outer display as a camera preview when taking a photo of someone else. The person being photographed can therefore see the framing directly.

A dedicated mode for taking photos of children

The iPhone Duo also features a child mode that displays Snoopy on the outer screen to attract a child’s attention when taking a photo.

Both cameras for FaceTime

The foldable design also opens up new possibilities for FaceTime.

The two displays and two cameras can work simultaneously, including for a three-way FaceTime call with one person on each side of the smartphone.

An A20 Pro chip

The iPhone Duo is powered by the A20 Pro chip.

It is accompanied by the new Apple C2 modem.

This configuration is designed to handle the large foldable display, multitasking and the new features developed specifically for the Duo format.

How long does the iPhone Duo battery last?

Apple claims battery life of up to one day.

To achieve this level of battery life despite its particularly slim design, the iPhone Duo uses two batteries.

The reference document also specifies that the smartphone does not use a silicon-carbon battery.

Is the iPhone Duo compatible with Apple Pencil?

Yes.

The iPhone Duo is compatible with Apple Pencil via USB-C.

This compatibility is particularly useful when the smartphone is unfolded and you are using its 7.6-inch display.

Is the iPhone Duo compatible with MagSafe?

Yes.

Contrary to some information that circulated before its launch, the iPhone Duo is compatible with MagSafe.

You can therefore use accessories compatible with this technology.

Touch ID returns to the iPhone Duo

The iPhone Duo also marks the return of Touch ID.

The fingerprint sensor is integrated directly into the side of the smartphone.
