CUPERTINO, CALIFORNIA / RankWire.AI / – Apple has launched the iPhone Duo, marking its debut in foldable smartphone technology. Starting at $1,999 in the U.S., the device was unveiled on September 9 at Apple’s headquarters in Cupertino. CEO John Ternus introduced the new model as part of the latest hardware lineup, with preorders opening on October 16 across more than 70 countries and regions. The initial units are expected to be available to consumers and in stores starting October 23.

Designed in a book-style format, the iPhone Duo features two Super Retina XDR displays. When the device remains closed, a 5.4-inch screen manages typical phone functions. Opening the device reveals a larger 7.6-inch interior display suitable for video, applications, gaming, and multitasking. The device’s housing is crafted from Grade 5 titanium, and the hinge mechanism comprises over 100 components. Additionally, it bears an IP68 certification for splash, water, and dust resistance.
Apple has modified its mobile software to optimize the use of the expanded foldable display. The iPhone Duo will be shipped with iOS 27.1, which introduces features specifically designed for this new screen format. Users are able to position two apps side by side and save favorite app pairings. When open, the phone can display two Home Screen pages simultaneously. Biometric authentication is available via Touch ID integrated into the side button, usable in either configuration.
Expandable display enhances multitasking and photography capabilities on the iPhone
The rear camera setup includes a 48-megapixel Fusion Main camera and a 48-megapixel Fusion Ultra Wide camera. The main camera offers a 2x optical telephoto option of professional quality and supports zero shutter lag. Users can preview selfies taken with the rear camera on the external display before capturing the shot. Duo Preview feature allows subjects to see the frame while another person controls the camera. The main camera is capable of recording 4K video at up to 120 frames per second with Dolby Vision.
