Why is the step data on the Xiaomi Watch S4 41mm inaccurate?

Question

Accepted Answer

The Xiaomi Watch S4 41mm is equipped with a built-in accelerometer, which captures motion data. This data is processed through algorithms combined with basic human body parameters to calculate metrics such as step count and calories burned.
If the step data on the Xiaomi Watch S4 41mm is inaccurate, please refer to the following factors that affect accuracy:
1. The principle behind calculating walking distance on the watch is based on your preset height, gender, and weight, which are used to estimate your step length. This estimated step length is then multiplied by your total step count to generate an approximate walking distance.
2. Different heights, weights, and genders can have different step lengths, causing deviations in calculations.
3. Factors such as arm swing amplitude, walking habit, human activity scene (e.g., walking, riding, driving, or showering), or complex arm movements (e.g., keyboard typing, moving the mouse, lifting and pulling objects) can influence step detection.
4. Due to the reasons mentioned above, the distance calculated by the watch is ultimately an estimated value. The watch is not intended to serve as a professional measurement tool for distance. Continuous optimization of the software algorithms will be carried out to improve the accuracy of these calculations.
Note:
The watch updates step counts multiple times per minute but does not provide real-time updates every second.
