The event is set for August 11th at 7PM local time in China, as confirmed by Xiaomi over at Weibo.
Earlier rumors suggest that the Xiaomi Mix Fold 2 will get better screens, Snapdragon 8 Gen 1 (or 8+ Gen 1) SoC, and probably the same triple rear camera system as the Honor Magic V smartphone (three 50-megapixel sensors).
In addition to the Mix Fold 2, Xiaomi will also unveil the new Buds 4 Pro TWS earphones and the Pad 5 Pro 12.4", which could be an updated Pad 5 Pro 11", getting better display, new camera system, and more.
The event is just two days away so we would not be surprised to see more leaks soon.
