Xiaomi's upcoming Xiaomi 18 series is rumored to feature a larger 6.4-inch display compared to its predecessor, the Xiaomi 17. According to tipster Digital Chat Station's Weibo post, this upgrade aims to accommodate a larger battery and camera system. The handset is expected to include a significant camera upgrade, specifically a 200MP periscope telephoto lens, surpassing the 17's camera capabilities.

These details suggest the phone will require more internal space. Recent rumors also point towards a September 2026 launch for the 18 series, potentially including the Xiaomi 18 Pro and Xiaomi 18 Pro Max, both powered by the next-generation Snapdragon 8 Elite Gen 6 Pro SoC. This follows earlier leaks about the Xiaomi 18's chipset and renders of the global Xiaomi 17.
