Xiaomi 18 Fold has gone on sale in China, intensifying the global foldable smartphone race just two days after Apple unveiled its first foldable iPhone. Xiaomi’s medium-fold design keeps the device passport-sized when closed and supports three apps side by side when fully opened. The phone runs Xiaomi’s in-house XRing O3 AI processor, with CEO Lei Jun claiming it outperforms Apple’s A19 Pro. CXMT supplies DRAM memory, while the phone is priced between $1,540 and $2,100 in China.
