Xiaomi officials describe the OS in only one word which is:


It improves the system with underlying 12 black technology optimizations. It is the only Android UI which removed more than 50 functions which were less used by the users, only to become lighter and faster.

The real battle will be between a high-end Android 8.0 phone vs a high-end MIUI 9 phone, and Android 8.0 might even win that race. Stay tuned for more comparisons!
