Apple unveiled the iPhone Duo, its first foldable smartphone, featuring a compact palm-size design with a 5.4-inch cover screen and 7.6-inch inner display. It competes with Samsung's Galaxy Z Fold 8 Ultra, which offers a larger 6.5-inch cover screen, 8-inch inner display, and superior camera specs, though the iPhone Duo provides better durability with an IP68 rating and starts at $1,999 versus the Z Fold 8 Ultra's $2,100.
Apple's iPhone Duo and Google's Pixel 11 Pro Fold are premium foldable phones priced around $2,000, both featuring rare IP68 water and dust resistance ratings. They differ in design philosophy: the Duo uses a compact passport-style layout with a matte inner display, while the Pixel 11 Pro Fold adopts a traditional book-style design with a larger screen. Both support dual apps and offer distinct trade-offs in form factor, display size, and camera capabilities.
