Apple iPhone Duo Is Launched: Apple’s First Foldable iPhone Brings a 7.6-inch Display and A20 Pro Chip

Key Highlights

• Apple’s first foldable smartphone, the iPhone Duo, has been officially unveiled
• 7.6-inch foldable inner display and 5.4-inch cover display with ProMotion
• Powered by the 2nm Apple A20 Pro chip with a 6-core CPU and 7-core GPU
• Dual 48MP rear camera system with 2x optical-quality telephoto

Apple has finally entered the foldable smartphone market with the iPhone Duo, its first iPhone with a flexible display. Unveiled on September 9, the device takes a book-style approach, combining a conventional 5.4-inch outer screen with a much larger 7.6-inch display that opens up for apps, gaming, video and multitasking.

The iPhone Duo is more than an iPhone with a folding screen. Apple has redesigned iOS 27 around the two-display form factor, added a custom hinge and nano-texture treatment to reduce the appearance of the crease, and replaced Face ID with Touch ID built into the side button.

With the A20 Pro chip, dual 48MP cameras, ProMotion displays and up to 2TB of storage, the Duo is positioned as a premium productivity and entertainment device rather than simply Apple’s answer to existing foldable phones.

Design & Build

The iPhone Duo folds horizontally like a book, turning a conventional smartphone into a larger tablet-like screen when opened. The inner display measures 7.6 inches, while the external cover screen measures 5.4 inches. Both displays use the same aspect ratio, allowing the transition between folded and unfolded modes to feel more consistent.

Apple has used a titanium-based hinge with an integrated magnet array designed to help the phone snap shut. The folding display sits over a titanium plate, while Apple has added a custom nano-texture finish to make the crease less visually noticeable and reduce reflections.

The outer display and rear panel receive Ceramic Shield protection, while the device carries an IP68 rating for dust and water resistance.

One notable design change is the removal of Face ID. Instead, Touch ID is integrated into the side button. The iPhone Duo is also eSIM-only, with Apple removing the physical SIM tray to create additional internal space.

Display

The main attraction is the 7.6-inch foldable Super Retina XDR display. When the phone is closed, users get a 5.4-inch cover display for regular smartphone tasks.

Both screens support Apple’s ProMotion technology, with refresh rates reaching 120Hz, and peak brightness can reach 3,000 nits. The inner display also uses a custom nano-texture finish designed to reduce reflections and make the centre crease less distracting.

The larger panel changes how the iPhone can be used. Watching videos, browsing documents and working with multiple apps should benefit from the additional screen area, while the outer display remains more convenient for quick messages, calls and everyday tasks.

Apple has also designed the two displays to work together rather than treating the inner panel as simply a larger screen.

Performance

The iPhone Duo is powered by Apple’s new A20 Pro chip, the same flagship silicon used in the iPhone 18 Pro and iPhone 18 Pro Max.

The chip is built using a 2nm process and features a six-core CPU, seven-core GPU and a dual 16-core Neural Engine configuration. Apple says the A20 Pro delivers up to 20% faster CPU performance and up to 40% faster GPU performance compared with the previous-generation A19 Pro, while Neural Engine computing power has also increased significantly.

The additional performance is important for the Duo because it has to drive a large high-refresh-rate foldable display while handling multitasking and Apple’s foldable-specific software features.

Apple has not yet provided independent benchmark results, so actual performance against competing foldables will need to be established through testing.

Camera

The iPhone Duo uses a dual-camera system on the rear, consisting of a 48MP Fusion Main camera and a 48MP Fusion Ultra Wide camera.

The Main camera includes an optical-quality 2x telephoto mode, while the Ultra Wide camera supports macro photography. The phone can record video at up to 4K resolution at 120fps, making it capable of handling demanding video workloads despite its foldable design.

On the cover display, Apple has included a 12MP Center Stage front camera. The inner display gets a separate under-display camera for FaceTime and selfies.

The under-display camera is one of the more interesting compromises in the Duo. Apple has not yet provided full hardware details for the sensor, so its image quality compared with the cover camera remains something that needs real-world testing.

Battery & Charging

Apple has designed the Duo around two battery sections, with the cells distributed across the two halves of the foldable chassis.

The company rates the phone for up to 31 hours of video playback when using the inner display and up to 44 hours when using the outer display. With both displays used equally, Apple claims up to 24 hours of use.

Wired charging can take the phone to 50% in around 20 minutes, while MagSafe or Qi2 wireless charging can reach 50% in approximately 30 minutes.

Apple has not officially announced the battery’s mAh capacity, so any specific capacity figures circulating online should be treated as unconfirmed.

Software & AI

The iPhone Duo runs iOS 27, but Apple has made significant changes to the software to accommodate the foldable design.

The interface can adapt as the phone is opened, folded or positioned at different angles. When unfolded, the home screen can display two pages simultaneously, while apps can be placed side-by-side using Split View.

Users can also create app pairs for frequently used combinations and switch between them quickly. This makes the large inner display considerably more useful for productivity than simply scaling a normal iPhone interface onto a bigger panel.

Apple has also redesigned elements such as the status bar, Dynamic Island and navigation controls to preserve more vertical space for content.

Connectivity & Special Features

The iPhone Duo supports 5G, Wi-Fi 7 and Bluetooth 6, with Apple’s C2 modem handling cellular connectivity. The device is eSIM-only worldwide.

Other features include MagSafe, Qi2 wireless charging, NFC, Ultra Wideband and satellite-based emergency communication.

The combination of a foldable display and software designed specifically around multiple windows is arguably the Duo’s most important special feature. Apple is treating the larger display as a productivity surface rather than simply a bigger screen.

Price & Availability in India

The iPhone Duo starts at ₹2,99,900 in India for the 256GB model. Apple is offering four storage configurations:

The phone is available in Star White and Night Sky.

In India, pre-orders begin on October 16, with sales starting October 23, 2026. Apple’s global availability is also scheduled for October 23.

Competition & Alternatives

Samsung remains Apple’s most direct competitor in the foldable category because it has years of experience with book-style foldables. The Duo’s biggest differentiator is therefore not simply its hardware; it is the combination of Apple’s ecosystem, iOS 27 and a foldable interface designed around the iPhone experience.

Final Verdict: Should You Buy It?

The iPhone Duo is the most significant change to Apple’s smartphone lineup in years. It is not simply an iPhone that happens to fold; Apple has redesigned iOS 27, the interface and several hardware components around the two-screen experience.

The biggest reasons to consider it are the 7.6-inch display, A20 Pro performance, foldable-specific multitasking, dual 48MP cameras and Apple’s ecosystem. It should appeal particularly to users who want an iPhone that can move between a conventional smartphone and a larger productivity device.

However, the price is the biggest obstacle. Starting at ₹2,99,900, the Duo costs considerably more than even Apple’s conventional Pro Max flagship. Buyers who primarily want the best iPhone camera or performance may get better value from the iPhone 18 Pro Max.

Best for: Users who specifically want a foldable iPhone, Apple ecosystem users, professionals and buyers who value multitasking and a larger display.

Consider alternatives if: You want better value, a lighter conventional smartphone, established foldable hardware or a lower entry price.

Bottom line: The iPhone Duo is Apple’s answer to a category that Android manufacturers have been developing for years, but Apple has taken a distinctly Apple approach: combine the foldable hardware with tightly integrated software. Whether that justifies the ₹2.99 lakh starting price will depend heavily on how well the hinge, inner display, cameras and iOS 27 experience perform over time.
