In addition to the iPhone 18 Pro, iPhone 18 Pro Max, and Airpods 5, Apple is also bringing something completely different this year: the iPhone Duo.
This is Apple's first foldable iPhone, featuring a book-like design that can be used as a regular smartphone when closed, and transforms into a large screen when opened.
Two Screens in One iPhone
The iPhone Duo has an outer screen of about 5.4 inches that can be used just like a normal iPhone. When unfolded, there is a 7.6-inch main screen that provides much more space for watching videos, reading, and working with multiple apps at once.
Both screens also support ProMotion, making scrolling and animations feel smoother.
More Comfortable Multitasking
The large screen isn't just for watching movies. Apple has also tailored iOS 27 to better suit a foldable design.
Users can run two apps side-by-side, move content between apps, and even use the iPhone Duo in a half-open position for specific needs.
This experience makes the iPhone Duo feel like a combination of an iPhone and a small tablet.
Powered by the A20 Pro Chip
For performance, Apple equips the iPhone Duo with the A20 Pro chip, the same chipset used in the iPhone 18 Pro Series.
This chip is paired with a vapor chamber cooling system to maintain performance during multitasking, gaming, and running AI-based features.
Dual 48MP Cameras
Unlike the iPhone 18 Pro which has three rear cameras, the iPhone Duo uses a 48MP Dual Fusion Camera System.
Although it lacks a dedicated telephoto camera, the camera system still offers flagship-grade photo and video quality. Its foldable screen design also allows the rear camera to be used for selfies with a live preview from the outer screen.
The Return of Touch ID
Another interesting highlight is the return of Touch ID.
On the iPhone Duo, the fingerprint sensor is placed on the side button. Apple chose this system to replace Face ID due to the foldable screen and its more complex body design.
