The iPhone Duo is the first foldable iPhone. Folded shut, you use it as a phone with a 5,4-inch screen; open it up and you have a 7,6-inch screen for reading, films and work. Open, it is 5,2 mm thin, and the frame and hinge housing are made of titanium.
- Two screens with ProMotion: up to 120 Hz inside and outside, with Always-On and Dynamic Island. The inner screen also works with Apple Pencil (USB-C).
- Two 48-megapixel cameras: a main camera and an ultra-wide camera, with 2x zoom in optical quality and video in 4K Dolby Vision.
- Up to 44 hours of video: on the outer screen, and up to 31 hours on the inner screen. With an adapter of 60 W or more, you can charge it to 50% in about 20 minutes.
- Touch ID and eSIM: you unlock with the side button and use two eSIMs at the same time. A physical SIM card does not fit.
- Fast connectivity: Wi-Fi 7 and Bluetooth 6 via Apple's own N1 chip, and USB-C with USB 3 up to 10 Gb/s.
