Apple has unveiled the foldable iPhone Duo, marking the company’s most significant iPhone design change in years and giving new CEO John Ternus a major product launch at the beginning of his tenure. The device introduces a book-style folding design, combining a five-point-four-inch outer display with a seven-point-six-inch internal screen when fully opened.

Ternus took over as Apple’s CEO from Tim Cook on September first, making the launch the first major iPhone event under his leadership. The presentation also gave Ternus an opportunity to establish his approach to product design after more than a decade of Cook-led Apple. The company positioned the Duo as a new interpretation of the iPhone rather than simply an extension of its existing smartphone lineup.

The announcement came with a deliberate reference to Apple’s past. Before revealing the foldable device, Ternus used the familiar “one more thing” phrase associated with Steve Jobs, linking the new product to one of the company’s most recognizable presentation traditions. Apple’s official iPhone Duo page describes the device as its first foldable iPhone and highlights its large internal display, flexible orientations and redesigned iOS experience.

Foldable iPhone Duo Brings a Major Design Shift

The foldable iPhone Duo changes the physical format that Apple has maintained since the original iPhone. Instead of a conventional flat smartphone, the device folds into a compact form similar in size to a passport and opens to reveal a much larger display.

Apple says the internal screen measures seven-point-six inches, while the external display measures five-point-four inches. The company designed the larger screen for activities including multitasking, entertainment and gaming. When opened horizontally, users can also place two applications side by side through the redesigned software experience.

The hardware combines the folding display with Apple’s A20 Pro chip and a vapor-based cooling system. The company also highlights a dual-battery architecture intended to provide all-day power while maintaining the thin profile of the device.

The Duo also introduces new ways to use the camera and interact with the operating system depending on how the phone is positioned. Apple has redesigned iOS twenty-seven to adapt to the different orientations and configurations created by the folding mechanism.

The company will begin accepting pre-orders on October sixteenth, with the iPhone Duo scheduled to become available on October twenty-third. The starting price is one thousand nine hundred ninety-nine dollars, placing it at the top of Apple’s current iPhone lineup. Reuters’ coverage of Apple’s foldable launch notes that the Duo enters a category where Samsung and other manufacturers already have established products.

Apple Enters a Foldable Smartphone Market

Foldable smartphones are no longer a new concept, but they remain a relatively small part of the global smartphone market. Samsung, Huawei and other manufacturers introduced foldable models years before Apple entered the category, giving competitors time to develop the technology and address early durability concerns.

Apple has historically entered established product categories after competitors and then attempted to differentiate its products through hardware integration, software and overall user experience. The iPhone Duo follows a similar strategy, with Apple emphasizing the relationship between the physical design and the operating system rather than treating the folding mechanism as the product’s only innovation.

The company’s entry could nevertheless increase consumer interest in foldable smartphones. Apple’s enormous installed base and tightly integrated hardware and software ecosystem give the category a potential path toward broader mainstream adoption.

The move also reflects Ternus’s background. Unlike Cook, whose leadership became closely associated with Apple’s operations, supply chain and business strategy, Ternus built his career around hardware engineering and product development. His first major iPhone launch therefore places particular attention on the physical design of the device and the engineering decisions behind it.

Associated Press coverage of John Ternus and the iPhone Duo describes the launch as a significant moment for Apple as the company begins its transition to a new CEO.

Siri AI Adds a Second Focus to Apple’s New Direction

The foldable iPhone was not Apple’s only major statement about its next phase. The company also highlighted artificial intelligence through its updated Siri experience and the broader capabilities of iOS twenty-seven.

The new Siri is designed to work with more of the information and applications already present on a user’s device. Apple’s approach places greater emphasis on personal context, privacy and on-device intelligence rather than relying entirely on cloud-based artificial intelligence services.

That strategy addresses one of the central criticisms Apple has faced during the recent artificial intelligence race: the company moved more cautiously than several technology competitors in introducing consumer-facing generative AI features. With Siri AI, Apple is attempting to make artificial intelligence a more integrated part of the operating system rather than a separate chatbot experience.

The approach could also become increasingly important as Apple looks to distinguish future iPhone generations through software. The company faces a difficult balance because new AI capabilities can potentially make existing devices more useful, while consumers may have fewer reasons to upgrade if major software features remain available on older hardware.

Apple is also entering this new period under different economic conditions than those that defined much of the previous iPhone cycle. Rising component and memory costs are putting pressure on device pricing, while consumers are becoming more selective about expensive smartphone upgrades.

TechCrunch’s report on the iPhone Duo highlights how Apple has adapted iOS twenty-seven around the foldable form factor, including new ways to use the larger display.

Cook remains involved with Apple as executive chairman following the leadership transition. His continued role is expected to keep him involved in areas where his experience remains valuable, including Apple’s political and international relationships.

The transition leaves Ternus with the challenge of defining Apple’s next product era while maintaining the operational strengths established during Cook’s tenure. The foldable iPhone Duo gives him an immediate opportunity to make that direction visible, combining a fundamentally different physical design with Apple’s expanding focus on artificial intelligence and software integration.

Apple Newsroom’s announcement of the iPhone Duo confirms that pre-orders begin October sixteenth and that the device will be available beginning October twenty-third.
