Xiaomi Smart Band 9 Pro bridges the gap between fitness tracker and smartwatch.

The bigger 1.74-inch AMOLED display at 1,200 nits makes stats easy to read mid-workout, and the built-in GPS — supporting five satellite systems (GPS, GLONASS, BeiDou, Galileo, QZSS) — tracks your outdoor routes accurately without your phone.

Positioning accuracy is up 33% over the Band 8 Pro, so routes map cleanly even in dense urban environments. The upgraded AFE sensor chip improves heart rate measurement accuracy by 15%, with continuous monitoring and alerts for abnormally high or low readings.

SpO2, sleep tracking with in-sleep breathing monitoring, and stress tracking with relaxation reminders run all day and night. Automatic detection covers six popular sports, while 150+ total modes handle everything else from swimming to yoga to HIIT.

A new low-power chip and larger 350mAh battery deliver 21 days of typical battery life — a 50% improvement over the Band 8 Pro — with fast 75-minute charging.
