The Xiaomi Smart Band 9 Pro Black is a rectangular wristband activity tracker with a 1.74-inch AMOLED display (336 × 480 px) and a black aluminum alloy case. It combines an expanded set of health and fitness features — including dual LED dual PD sensors, upgraded AFE chip and an independent GNSS supporting five satellite systems — with multiple strap options (leather, magnetic, TPU) and 5ATM water resistance. The device is designed for continuous monitoring, on-wrist workout guidance and accurate route tracking without a phone. The built-in 350 mAh battery and power-optimized chipset provide long endurance and fast charging.

How to use

Charge the band fully before first use. Put the band on your wrist and pair it with the Xiaomi/compatible fitness app via Bluetooth to enable GNSS, activity tracking and advanced health monitoring. Select a sport mode or use automatic recognition for supported activities. For outdoor routes, enable GNSS on the band to record accurate positioning without your phone. Use the watch faces and strap options to adapt appearance for daily wear or specific workouts.

Recommendations

Wear the band snugly but comfortably on the wrist for best heart rate, SpO2 and sleep measurements; rinse and dry straps after swimming or intense workouts, and keep the 2.5D cover glass clean to avoid false touches. For optimal GNSS accuracy, allow the band a clear view of the sky during outdoor activities.
