CUPERTINO, CALIFORNIA / RankWire.AI / – Apple has expanded its iPhone lineup with the introduction of the iPhone Duo, marking its entry into foldable smartphones. The company revealed the device on Sept. 9, with preorders set to open on Oct. 16. U.S. pricing starts at $1,999, while in the UAE, the starting price is AED 8,499. Sales are scheduled to commence on Oct. 23 across more than 70 countries and regions. This launch introduces Apple’s first book-style smartphone featuring separate outer and inner displays.
The iPhone Duo features a 5.4-inch outer screen for everyday tasks when the device remains closed. When opened, it reveals a 7.6-inch Super Retina XDR display, optimized for larger apps and multitasking. Both screens support ProMotion and Always-On capabilities, with outdoor brightness reaching 3,000 nits. The device’s enclosure is crafted from Grade 5 titanium, and the hinge comprises over 100 components. Additionally, the phone has an IP68 rating for dust and water resistance.
Software is crucial in utilizing the extra display area of the foldable iPhone. Apple developed iOS 27.1 to support both closed and open modes. Split View allows users to position two apps side-by-side on the internal screen, while multitasking with two windows of the same app is also possible, along with saving custom app arrangements for later. The expanded display accommodates two Home Screen pages, and Touch ID remains embedded in the side button.
Enhanced multitasking options enabled by larger screen
The camera array includes a 48-megapixel Fusion Main camera alongside a 48-megapixel Fusion Ultra Wide camera. The main sensor also features an optical-quality 2x telephoto option. Duo Preview allows users to view a live image on the outside display while someone else captures the shot. The outer screen doubles as a viewfinder for selfies taken with the rear cameras. Video recording supports 4K resolution at up to 120 frames per second with Dolby Vision compatibility.
Powered by the A20 Pro chip built with 2-nanometer technology, the iPhone Duo incorporates a six-core CPU, a seven-core GPU, and dual 16-core Neural Engines. A vapor chamber manages thermal regulation inside the foldable device. The phone also features batteries on each side. Apple estimates up to 31 hours of video playback on the inner display and as much as 44 hours on the outer display.
October release marks Apple’s entry into foldable smartphones
Storage options range from 256GB to 512GB, 1TB, and 2TB. The iPhone Duo will be available in star white and night sky finishes. The initial retail release begins on Oct. 23, following a preorder window that opens a week earlier. Additionally, 28 more countries and regions will receive the device on Oct. 30. It features an eSIM-only design globally and supports Wi-Fi 7, Bluetooth 6, and Thread connectivity.
By launching the iPhone Duo, Apple enters a competitive foldable smartphone market that already includes offerings from several major manufacturers. Its design combines a traditional outer screen with a larger internal workspace for apps, photos, and videos. The hardware is integrated with Apple’s proprietary chips, operating system, and camera technology. The company has maintained core iPhone features such as biometric authentication and its existing software ecosystem. Customers can expect to receive their first units approximately six weeks after the September announcement.
