The Verdict
Editor's ChoiceThe iPhone Duo represents Apple's long-anticipated debut into foldable computing, offering a seamless book-style form factor that unfurls into a 7.6-inch 3000-nit LTPO OLED canvas. Powered by the A20 Pro chip and a custom multi-tasking edition of iOS, the Duo bridges the gap between iPhone mobility and iPad productivity. With aerospace-grade zero-crease hinge engineering, an under-display front camera, and dual 48MP shooters backed by a 5000 mAh dual-cell battery, it marks the most significant evolution of Apple hardware in a decade.
