Why is there a large deviation in the calorie calculation on the Xiaomi Smart Band 10?

For your reference, here are the reasons for a large deviation in the calorie calculation on the Xiaomi Smart Band 10:
1. Calorie calculation on the Xiaomi Smart Band 10 is based on factors like heart rate and wrist movement. With each product generation, the algorithm is upgraded to incorporate more variables. Therefore, the calculation logic can differ from earlier models;
2. Passive calories (daily calories): These are calories burned during daily activities without starting a workout manually. When the band is not worn or you are asleep, calorie count will not increase. However, light activities, such as office work, even without steps, can still generate calorie readings based on movement. The amount of calories depends on both the intensity and duration of the activity.
Note:
On models like the Xiaomi Smart Band 7 and earlier, calories are only calculated when step count or heart rate data is available.
3. Active calories (workout calories): These are calories recorded during manually initiated workouts and are mainly affected by heart rate and your profile (e.g., age, weight, height). The higher the heart rate and the longer the workout duration, the more calories are burned;
4. If you find your calorie data abnormal, please first check if your weight, height, and age are correctly set in the Mi Fitness APP. If the information is accurate and issues persist, you can submit feedback for further data analysis.
