Why is the step count on the Redmi Watch 5 Active inaccurate?

Pace principle: The watch uses a built-in accelerometer. The data detected by the accelerometer is then combined with an algorithm and basic information of the human body to ultimately convert the information into steps, consumption and other information.
Factors that affect the number of steps recorded by a watch:
1. The principle of measuring the walking distance of a watch is to estimate your step length according to the height, sex and weight set by yourself, and then multiply it by your step number to obtain an estimated value;
2. Because your mileage can vary, and people of the same height, sex, and weight can have different step counts, the final calculated value can also have large errors;
3. The accuracy of step counting, that is, the number of steps you take, is influenced by many uncertain factors related to your behavior, such as the amplitude of your arm movements and your walking habits. There are many scenarios where human activity occurs (such as walking, riding, driving, bathing, etc.), and your arm movements can be complex (such as typing on a keyboard, moving a mouse, lifting and pulling objects, etc.);
4. Due to the reasons mentioned above, the final calculated distance on your watch is also an estimate. The watch cannot be used as a professional measurement tool for measuring distance. We will continue optimizing the software algorithm to calculate more accurate data.
