Why is the heart rate test data of Xiaomi Watch S3 inaccurate, sometimes very high, sometimes very low, rising and falling?
Inaccurate heart rate measurement may be caused by wearing style, skin color, hair, reduced blood perfusion, low temperature, vasoconstriction, or dirt or water stains between the watch and wrist;
To ensure measurement accuracy, please wear it tightly, keep the device from sliding down when your arm is shaking, and wear the device one finger above the wrist bone.
For cold weather conditions, due to the influence of low temperature, the capillaries of the human body's extremities shrink, and blood flows back to the trunk and organs, making it more difficult to obtain photoelectric heart rate signals at the wrist, and it is also easier to lose the true heart rate signal during exercise. Therefore, it is recommended to fully warm up before exercise to speed up the blood flow and facilitate the sensor to obtain more accurate heart rate data.
Please ensure that the bottom case of the watch is clean and dry, the temperature of the watch is not too low or too high, there is no sweat or foreign matter on the wrist, and it must be worn comfortably and snugly;
At the same time, engineers are also trying their best to optimize the solution. Please wait for subsequent upgrades and updates.
