What’s New in Apple’s First Foldable Smartphone?

The iPhone Duo is Apple’s first foldable smartphone, unveiled in September 2026. When unfolded, it has the thinnest body of any iPhone ever made. Let’s explore the key features of the iPhone Duo:

1. Two displays. When folded, it feels like a familiar smartphone. Unfold it, and you get a device with a huge inner screen. You can also use both displays simultaneously, for example, during video calls.
2. Powerful A20 Pro chip. The powerful processor unlocks the full potential of the iPhone Duo, enabling fast switching between apps, smooth performance on both screens, and new Apple Intelligence features.
3. Longer battery life. With improved battery life, you can scroll through social media and watch your favorite videos all day without worrying about recharging.
4. Advanced camera system. The cameras are optimized for the foldable design. Activate Duo Preview to see a preview of your shot directly on the outer display.
5. iOS and Apple Intelligence. iOS 27 is optimized for the foldable design, making it easier to multitask and use Apple Intelligence features. You can split the screen between two activities, such as watching videos while interacting with Siri AI.

The inner display features an innovative nano-texture coating that effectively diffuses light and minimizes distracting glare.

Why Did Apple Take So Long to Release a Foldable iPhone?

Apple hasn’t revealed why its first foldable smartphone is only arriving now. Some experts believe the company may have taken extra time to perfect the new design and ensure it meets Apple’s standards.

iPhone Duo Design and Folding Mechanism

The iPhone Duo features a Grade 5 titanium body with a mirror-polished finish. The back panel is protected by Ceramic Shield, while the front features Ceramic Shield 2, which is three times more scratch-resistant than the first generation. Apple’s first foldable iPhone comes in two colors: Night Sky and Star White.

A precision-engineered hinge ensures smooth folding and provides reliable support for the central part of the display. To increase the structural rigidity of the device, Apple has incorporated:

• additional internal reinforcement ribs;

• ceramic inserts in the antenna components.

When folded, the iPhone Duo measures 117.8 × 84.1 × 11.3 mm. When unfolded, its dimensions are 117.8 × 164.6 × 5.2 mm.

You’ll be able to order the iPhone Duo from iSpace shortly after its official release. We offer only genuine devices backed by the manufacturer’s warranty.

Outer and Inner Displays

The smartphone features two Super Retina XDR displays:

• a 7.6-inch inner display;

• a 5.4-inch outer display.

Both screens have the same aspect ratio and support ProMotion. Maximum outdoor brightness reaches 3,000 nits.

The large inner display lets you watch videos while chatting in a messenger app or work on a document while taking notes.

Processor and Performance

The new iPhone Duo features the A20 Pro chip with a 6-core CPU that is up to 20% faster than the CPU in the previous-generation chip. The 7-core GPU delivers up to 40% better performance, while memory bandwidth has increased by 50%. The new Dual 16-core Neural Engine makes on-device AI tasks even faster, delivering up to 50% more computing power.

Sustained performance has improved by up to 35% compared to the iPhone 17 Pro, thanks to:

• the powerful A20 Pro chip;

• a custom vapor chamber;

• an advanced cooling system.

These improvements are particularly noticeable during prolonged intensive use, such as running resource-intensive AI tasks.

The new model is available in four storage configurations:

• 256GB;

• 512GB;

• 1TB;

• 2TB.

A dedicated display engine manages both screens and ensures smooth transitions between them.

iPhone Duo Cameras

The device features an advanced camera system with two rear cameras and two front cameras. For photographing children, the Kid Cue feature displays an animation on the outer screen to capture their attention and encourage them to look directly into the lens. This makes it easier to capture the perfect shot.

The 48MP Fusion Main camera supports:

• taking photos at resolutions of up to 48MP;

• shooting at 24MP by default;

• using 2x optical-quality zoom to capture distant subjects;

• capturing sharp images with zero shutter lag.

The 48MP Fusion Ultra Wide camera is ideal for taking close-up photos of small objects. A new FaceTime camera is located beneath the inner display. During FaceTime calls, it lets you show the person you’re talking to both yourself and what’s happening in front of your smartphone using the 48MP Fusion Main camera.

Battery and Battery Life

The new iPhone Duo features a dual-cell battery. Its two cells are located in separate halves of the device but function as a single system. Battery life during video playback depends on which display you use:

• up to 44 hours when using the outer display;

• up to 31 hours when using the inner display;

• up to 24 hours when using both screens equally.

With wireless charging, you can quickly recharge the battery to 50% in just 30 minutes. Wired charging is even faster, taking only 20 minutes.

How Does iOS Work on the Foldable iPhone?

The new device runs iOS 27.1, optimized for its foldable design. The system automatically adjusts the interface to whichever screen you’re using. Content scales proportionally when switching between displays.

An enhanced Dynamic Island is positioned vertically along the side of both screens. It expands to display notifications and Live Activities.

For the first time on an iPhone, Split View lets you open two apps simultaneously on the inner display. Previously, this feature was only available on the iPad.
