Apple has finally announced its long-anticipated foldable iPhone, the iPhone Duo, arriving more than seven years after the first Samsung Galaxy Fold hit the market. In tech years, that's practically an eternity - or at least several product cycles of 'we're working on it.'

Rumors about a folding iPhone have been swirling since at least 2017, when optimists predicted production might begin in 2020. That didn't happen. Instead, rivals like Samsung, Google, Huawei, Oppo, Honor, and others have released myriad foldable Android phones - book-style, flip-style, and even trifolds. The market, however, remains niche: foldables accounted for just 1.6 percent of all smartphone sales in 2025. But hey, when you're Apple, even a small slice of the pie is a lot of pie.

Various reports claimed Apple was developing different form factors, including larger foldable iPads. But over the last two years, speculation has centered on a short, wide book-style foldable iPhone, roughly the size and shape of a passport when closed. That expectation likely prompted Huawei, Samsung, and Xiaomi to all release foldables in that form factor this year - proof that Apple's influence remains outsize, even when the company hasn't actually shipped a product yet.
