Overview
The Xiaomi 18 Fold is a book-style foldable smartphone with a wide 7.58-inch inner display and a 5.38-inch cover screen. It combines Xiaomi’s XRing O3 processor with a triple rear-camera system led by a 200 MP main camera, a 6,000 mAh silicon-carbon battery and support for wired and wireless fast charging. The wider design gives the inner screen a more landscape-oriented shape than many traditional book-style foldables, making it suited to multitasking, reading, video and side-by-side apps.
