Just as the original 2007 iPhone revolutionized how we interact with touchscreens, Apple is now poised to redefine the foldable smartphone market with its upcoming iPhone Duo. For years, foldables have remained a niche category, struggling to gain mainstream traction due to hardware trade-offs like visible screen creases, fragile displays, and battery limitations. While pioneers like Samsung, Huawei, and Royole navigated the "growing pains" of the industry—ranging from the infamous "foldgate" scandals to experimental designs—Apple is leveraging its signature "second-mover" strategy. By waiting for supply-chain technology to mature, the company is betting that it can perfect the foldable experience where others have faced significant hurdles.

The journey of foldable phones has been a volatile mix of innovation and trial-and-error, spanning from the clunky hinges of the 2018 Royole FlexPai to the sleek tri-folding devices released by Huawei and Samsung in recent years. As the market shifts toward the "passport" aspect ratio—a shape optimized for media consumption—industry analysts anticipate that Apple’s entry will serve as a powerful catalyst for growth. With foldable shipments projected to rise significantly, the tech giant’s participation is expected to elevate premium competition, potentially transforming these devices from expensive experiments into everyday essentials for the average consumer.
