On the Xiaomi Smart Band 9 Pro, if continuous monitoring is enabled, you can directly see heart rate data by tapping the heart rate icon. Once you enter the Heart rate APP, rest your arm flat, and you’ll see an animation during measurement. When complete, the heart rate reading will display.
On the Mi Fitness APP, you can go to [Health] >> [Heart rate] to access a comprehensive view. This includes a heart rate graph for the entire day, along with the highest, lowest, and resting heart rates, as well as alerts for excessively high or low heart rates.
Note:
Improper wear can affect heart rate signal accuracy. Light leakage from loose wear, arm movements, and minor shifts of the band on your skin can disrupt measurements. A band worn too tightly, raising the arm, or clenching a fist can also impact blood flow, potentially interfering with heart rate signals.
