Notes:
1, Mi Band 3 displays the 5 latest message notifications. Each message can display up to 3 screens.
2, Source of data: According to GB/T 30106-2013, it was tested by the National Quality Supervision and Inspection Center for Watches and Watches, report number: QT1803032, waterproof rating 5ATM (equivalent to a depth of 50 meters underwater). It can be worn while showering, swimming in the pool and shoal, but it is not suitable for saunas and diving.
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.
5, Supports MIUI Android 4.4 or above OS, or Android 5.0 and above, and supports Smart Lock models.
6, Mi Band 3 has more than 30 functions. For details about the specific functions please refer to the main product ad.
7, Battery Life data was measured by Huami Science and Sports laboratories using the factory default settings. 50 notifications were received and displayed every day, one alarm clock was vibrated for 5 seconds, and the touch key pressed 10 times, every other operations was run for 2 minutes, manual measuring of heart rate was done 3 times, exercise for 1 hour per week (entering the running function to detect real-time heart rate, heart rate reminder was turned off), and start the daily use mode test of the Mi Fit APP. 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.
8, The Mi Band 3 main unit was manually disassembled from the wristband and tested 2000 times through factory artificial simulation tests. The specific way of disassembling is: loading the main body of the wristband from the front, and removing it from the back; and then loading it into the main body of the wristband from the back, and remove it from the front. After the dismantling test is completed, the wristband is not significantly deformed, and the main body was confirmed to be firmly in place after being loaded into the wristband.
