Apple unveils $1,999 foldable iPhone Duo at first keynote under CEO John Ternus

Leadership debut and keynote announcements

On September 9, 2026, Apple held its autumn product presentation at the Steve Jobs Theater at its Cupertino headquarters. The event marked the public debut of John Ternus as chief executive officer, following his assumption of the role on September 1 in succession to Tim Cook. Cook opened the pre-recorded broadcast with a brief address before handing over to Ternus and other executives. The presentation introduced multiple hardware lines, including the iPhone 18 Pro and iPhone 18 Pro Max, the AirPods 5 wireless earbuds, and updated smartwatches in the Apple Watch Series 12 and Apple Watch Ultra 4. After an hour of product announcements, Ternus concluded the keynote by presenting Apple's first foldable smartphone.

Finally, there is one more thing...

Display design and structural engineering

The iPhone Duo uses a dual-display configuration consisting of a 5.4-inch (13.71 cm) external panel and a 7.6-inch (19.30 cm) flexible OLED interior screen. The internal display opens flat with minimal visible creasing, adapting interface icons and application layouts to prevent letterboxing on the expanded aspect ratio. Structural durability is provided by a Grade 5 titanium housing, with the device certified to IP68 standards for resistance to dust and water immersion. The folding screen supports Apple Pencil stylus input across both display segments, targeting professionals who use tablet-sized interfaces for reading and editing documents.

Internal hardware, cameras, and connectivity

Processing is handled by Apple's A20 Pro system-on-chip, which also powers the iPhone 18 Pro lineup. The rear camera system pairs a 48-megapixel ultra-wide camera capable of recording 4K video at 120 frames per second with a secondary 2x telephoto sensor. A 12-megapixel FaceTime camera is positioned beneath the flexible interior display panel. When taking photographs using the expanded screen, the exterior display plays animations facing outward to direct the subject's gaze. The battery supports up to 31 hours of video playback on the internal screen. The device operates exclusively on eSIM profiles without a physical SIM card slot, and relies solely on Touch ID biometric authentication rather than Face ID.

Market competition and commercial release

Apple's entrance into the foldable segment follows several established competitors in the category. Chinese manufacturer Royole released the first commercial foldable device, the 1,300-euro FlexPai, eight years earlier, while Samsung Electronics introduced its folding line seven years prior, alongside competing devices from Alphabet's Google and Huawei Technologies. Research firm Counterpoint recorded 100 million folding smartphones sold across all manufacturers leading into the release. The iPhone Duo starts at $1,999 in the United States and 2,339 euros in European markets, with official retail shipments scheduled to begin on October 23, 2026.
