The Redmi Watch 5 Active, like many fitness trackers, uses algorithms to estimate calorie burn based on activity data such as steps taken, heart rate, and other sensor inputs. However, the accuracy of calorie burn tracking can vary significantly depending on several factors, including the user's metabolism, activity type, and individual physiological differences.
In general, fitness trackers like the Redmi Watch 5 Active tend to provide a rough estimate of calorie burn rather than precise measurements. This is because they rely on generalized formulas that may not account for individual variations in metabolism or the specific intensity of activities. For instance, a video review of the Redmi Watch 5 Active noted that while it provides a good estimate of calories burned, it might not be as accurate as other devices like the Galaxy Fit 3 or Xiaomi Smart Band 9 in step counting, which is a crucial factor in calculating calorie burn[1].
The Redmi Watch 5 Active is equipped with a heart rate sensor and accelerometer, which help in tracking physical activities and estimating energy expenditure. However, the accuracy of these sensors can also influence the overall calorie burn estimation. Reviews suggest that while the heart rate tracking is generally accurate, step counting and calorie estimation might not be as precise for everyone[1][3].
In comparison to other Redmi models, such as the Redmi Watch 5 Lite, there are similar issues with calorie and step counting accuracy. Users have noted that these devices sometimes miscalculate steps and calorie burn estimates, which can be frustrating for those relying on precise data for fitness tracking[4].
Overall, while the Redmi Watch 5 Active provides a useful estimate of calorie burn, it should be used as a general guide rather than a precise measurement tool. For more accurate tracking, users might need to consider additional factors or use other devices that offer more advanced features or better sensor accuracy.
