Apple has unveiled the iPhone Duo, the company's inaugural foldable smartphone, ending years of speculation about such a device 2. The iPhone Duo features a 7.6-inch internal display and a 5.4-inch external display, with the inner screen offering 50% more screen real estate than the iPhone 18 Pro Max 1. The external screen boasts a screen-to-body ratio exceeding 90% 1. The device runs iOS 27 and comes equipped with an A20 Pro chip featuring dual 16-core neural engines, a 48MP dual-fusion camera system, and an IP68 water and dust rating with a Grade 5 titanium frame 1.

The foldable mechanism represents a significant engineering achievement. According to Apple hardware chief Johny Srouji, the hinge was designed using AI algorithms and 3D printing technology, with the process involving laser scanning of the hinge topology followed by 3D printing of up to 25 layers of microscopic polymer material to eliminate wrinkles 3. The device incorporates a nanotexture coating and multi-layer lamination strategy to enhance durability 3. The internal display features a matte finish with a nearly imperceptible crease and a smooth folding mechanism 2.

The iPhone Duo delivers impressive battery performance, supporting 30-minute charging to 50% capacity and up to 31 hours of video playback on the internal screen 1. Storage options range from 256GB to 2TB 1. Pre-orders begin on October 16, with availability starting October 23 at apple.com and authorized retailers 4.
