Apple has unveiled the iPhone Duo, its first foldable iPhone, combining a 7.6-inch inner display with a 5.4-inch outer screen. The device was announced on September 9, with pre-orders scheduled to open on October 16 and sales beginning October 23 in more than 70 countries and regions, including India.

When unfolded, the iPhone Duo becomes the thinnest iPhone yet and offers Apple’s largest iPhone display. The inner Super Retina XDR screen is 50% larger than the iPhone 18 Pro Max, while the outer display provides 90% of the screen area of the iPhone 18 Pro. Both screens feature ProMotion, Always On and up to 3,000 nits of outdoor brightness.

The device uses a grade 5 titanium enclosure and includes an IP68 rating for splash, water and dust resistance. Apple has also incorporated Ceramic Shield and Ceramic Shield 2, along with a precision hinge built from more than 100 components.

The iPhone Duo is powered by Apple’s A20 Pro chip and a custom vapor chamber designed to manage heat during demanding workloads. A dual-battery system supports up to 31 hours of video playback on the inner display and up to 44 hours on the outer display.

Photography is handled by a 48MP Fusion Main camera with an integrated optical-quality 2x Telephoto, alongside a 48MP Fusion Ultra Wide camera. The foldable format also enables features such as Duo Preview, Smart Take and Duo FaceTime.

Apple has redesigned iOS 27 for the larger foldable screen, adding Split View multitasking and other interface changes. The phone also supports Apple Intelligence and the new Siri AI, which is rolling out in beta with iOS 27.

The iPhone Duo will start at $1,999 in the US and will be offered with 256GB, 512GB, 1TB and 2TB storage options. It will be available in star white and night sky.
