Apple released the Duo foldable phone on September 9, 2026, saying it integrates AI into its hinge design to improve durability. It is the company's first foldable phone update since entering the foldable phone category.

Apple reported the Duo’s hinge is built with AI algorithms and 3D printing, measured on its durability and alignment. That compares with traditional manufacturing methods used in prior devices.

The Duo is built on custom hardware and targets users seeking durable foldable phones. Availability begins in late 2026, initially for all customers.

"During manufacturing, we use AI algorithms to precisely match each individual hinge with its best-fit housing to ensure perfect alignment," said Johny Srouji, Apple’s chief hardware officer. The hinge also features a confocal laser and 3D printing to eliminate residual waviness.

The announcement follows Apple’s Surprise and Shine event. The company frames the significance as a step toward improving foldable phone durability.

Apple did not say how long the Duo’s protections will last, and the long-term durability remains to be seen. The company said it has integrated innovative protections into the Duo’s design.
