The iPhone Duo is Apple’s first foldable iPhone, and it opens like a small book into a 7.6-inch screen. Closed, you hold a 5.4-inch outer display that fits in a pocket. Both screens share the same aspect ratio, so a video or app scales cleanly as you move between them. Stand it up on a table, and it works hands-free for calls or video. Apple showed the phone on September 9 at its Surprise and Shine event in Cupertino, where new chief executive John Ternus led his first keynote. He said rival foldables often feel like two phones stuck together. The Duo tries to feel like one device that changes size when you need it.
What the screens and camera can do
Open the Duo and the inner display runs 50 percent larger than the iPhone 18 Pro Max. A custom nano-texture finish cuts glare and hides the crease, the seam that has annoyed foldable owners for years. Peak brightness reaches 3000 nits, so the screen stays readable outdoors. Inside, an under-display FaceTime camera keeps the view whole, with no notch breaking the screen. The rear camera leans on a 48MP Dual Fusion system with a main and an ultra-wide lens. There is no telephoto, a trade Apple made to save room in the thin body. Smart Take reads the scene and snaps the photo when everyone poses, so you can stand in the shot instead of behind it. You can also shoot 48MP photos and 4K video at up to 120 frames per second.
iPhone Duo specs that matter for daily use
The iPhone Duo specs point to a phone built for long, heavy days. Inside sits the A20 Pro chip with a vapor chamber that spreads heat during games and video edits. Apple pairs it with a dual-battery design that fits more cells into the frame. You get up to 31 hours of video on the inner screen and up to 44 hours on the outer one. Plug it in, and it reaches 50 percent in about 20 minutes. A Grade 5 titanium frame and a precision hinge give the body its strength, and Touch ID moves to the side button in place of Face ID.
iPhone Duo prices are ridiculously high
Here is the part your wallet cares about. The iPhone Duo price starts at $1,999 for 256GB in the United States, which makes it the most expensive iPhone in the lineup. In the UAE, iPhone Duo starts at AED 8,499 for the 256 GB, AED 9,349 for the 512 GB, AED 11,049 for the 1 TB, and the laptop-price level of AED 13,599 for the 2 TB. Preorders open October 16, and the iPhone Duo release date lands on October 23. Apple plans a first wave across more than 70 countries, then adds 28 more on October 30. For comparison, Samsung’s Galaxy Z Fold 8 starts near $1,899.
Why the foldable iPhone arrives only now
Apple waited years while Samsung and others sold foldables. Now the foldable iPhone brings iOS 27 features built for two screens, like Split View and apps that respond to how you hold the phone. eSIM handles the connection, since there is no SIM tray anywhere. Apple Pencil support arrives later in 2026. That gap of a few weeks after the iPhone 18 Pro points to a slower, careful rollout for a harder build. If you have wanted a phone that turns into a small tablet without feeling clumsy, this is Apple’s answer, and you can hold one this month.
