3, In the Sports Mode of the Mi Fit APP, if you open any of the outdoor running, indoor running, cycling, or walking activities, you only need to lift your wrist to view the motion in real time on the screen of the Mi Band 3. Key data such as duration, mileage, heart rate, and speed are very quickly and conveniently displayed.
4, Mi Band 3 currently uses two different heart rate sensors, both having a slightly different appearance in structure. Strict comparison test by Huami Science and Technology Laboratory revealed that the performance is consistent in terms of static heart rate, dynamic heart rate, and overall performance. In addition, 24-hour heart rate monitoring can be turned on in the Mi Fit APP. However, when this function is turned on, the power consumption is larger and the overall battery life becomes shorter.

In actual use, the battery usage time is dependent on various factors such as settings, operation frequency and environmental factors, and may be different from the laboratory data results.
