Troubleshooting
1.Q: Xiaomi Watch S1 is inaccurate in step counting?
A: The principle of step recording: The watch has a built-in acceleration sensor. The data detected by the acceleration sensor is combined with the basic information of the algorithm and the human body, and finally the information is converted into steps, consumption and other information.
Factors affecting the number of steps recorded by the watch: 1. Because the principle of the watch's measurement of walking distance is to estimate the user's step length according to the height, gender and weight set by the user, and then multiply the number of steps taken by the individual to obtain an estimated value.
2. Because the step length will vary from person to person, and the step length may be different for people with the same height, gender, and weight, the final calculated value will also have a large error.
3. The accuracy of step counting, that is, the number of steps taken, there are also many uncertain factors that will have a great relationship with each person's behavior habits, such as the habit of walking with arm swings, etc. a lot (such as walking, riding, driving, bathing, etc.), arm movement
More complex operations (such as keystrokes, moving the mouse, lifting and pulling objects, etc.). 4. It is precisely because of the above reasons that the final calculated distance of the watch is also an estimated value, and the watch cannot be used as a professional measuring tool to measure the distance. Subsequent optimization will continue to be performed on the software algorithm to calculate a more accurate data.

2.Q: Why is GPS positioning slow sometimes?
A: GPS start is divided into cold start, warm start and warm start. Cold starts generally occur in the following situations:
1. When the GPS function of the watch is used for the first time.
2. The satellite ephemeris information is lost when the battery of the watch is exhausted and the power is turned off.
3. When the watch is turned off, the displacement exceeds 200 kilometers.
Since the GPS positioning system of the watch needs to download satellite ephemeris information in a cold start state, its positioning time will be much longer than that of a warm start and a warm start. Considering the way the watch is worn and the influence of the arm on the GPS antenna, it is recommended to choose an open field during cold start (including the first positioning), and keep the dial pointing to the sky when the watch is worn normally. Complete the download of ephemeris and GPS cold start positioning. The specific positioning time is related to the weather and surrounding environment.
If the watch does not move too much after the last positioning, and the time interval from the last positioning is less than 2 hours, the watch GPS can be warmed up. In an open field, when the watch is worn normally and the dial points to the sky, the positioning can be completed in about 5 seconds. The exact time depends on the weather and surrounding environment.
When GPS positioning is slow, you can re-open the AP and reconnect the watch to synchronize data, which will greatly improve the GPS positioning speed.

3.Q: Why sometimes, there is no movement track or the track is lost after exercise?
A: 1. Before starting the exercise, please check to make sure that the GPS positioning is successful on the exercise preparation interface (that is, the GPS symbol turns blue and there is a vibration prompt) and then start exercising.
2. GPS is affected by many factors, such as tall buildings around, complex terrain, overpasses, tunnels and complex electrical signal environments, and harsh weather conditions such as sandstorms, rainstorms, and other harsh natural weather will cause GPS positioning failures, motion trajectory lost etc.
3. To ensure a more accurate GPS movement track, it is recommended to keep connected to the mobile phone and watch during the exercise when starting the exercise.

4.Q: Why does the motion trajectory drift?
A: GPS drift means that there is a gap between the GPS positioning and the actual position, and there is a continuous trajectory with a certain interval from the actual route during the movement. There are many factors that affect GPS, such as tall buildings around, complex terrain and complex electrical signal environment, severe weather conditions such as sandstorms, rainstorms, and other severe natural weather.

5.Q: Why doesn't exercise data generate after exercise?
A: 1. Please confirm whether the watch is worn normally and whether the heart rate is normal.
2. After the exercise is turned on, whether the exercise time or distance reaches the minimum standard of exercise recording.
3. It may be caused by improper wearing and the heart rate is not monitored normally.

6.Q: Why does the watch still display the pace information when I stop exercising in sports mode?
A: The mileage and pace during exercise are determined by time calculation. After 10 seconds of stopping the exercise, the pace will stop.

7.Q: What should I do if Xiaomi Watch S1 cannot be charged?

4. Press and hold the up button on the watch for 15 seconds to force restart the device, and then put it on the base to charge.
5. If the above inspection is invalid, you can apply for after-sale inspection.

8.Q: Why does Xiaomi Watch S1 display heart rate when worn on other objects?
A: The watch analyzes the individual's heart rate by collecting signals from optical sensors. Due to the limitation of the working principle of the sensor itself, if the watch is worn on other objects, or there is an obstruction in front of the heart rate sensor, if the heart rate sensor detects changes in the light signal, the heart rate value may be measured. Therefore, when the algorithm is compatible with the aforementioned signals, The latter signal will be misjudged, resulting in the calculation of the heart rate value.

9.Q: Why can only a small number of dials be stored on the watch side?
A: Due to the large memory occupation of the dial, in order to ensure the running rate of the watch system, the number of dials will be limited to a certain extent. When the number of watch faces exceeds the limit, you can delete the installed watch face and reinstall a new watch face.

39.Q: Charging with a non-standard charging base, the problem of long charging time?
A: Because the charging power of different charging bases is inconsistent, when charging with non-standard bases, in order to ensure charging safety, the charging temperature and charging efficiency are limited. It is recommended that you use the original standard charging bases for charging.

40.Q: Heart rate detection is inaccurate?
A: The watch uses photoplethysmography (PPG) technology to detect human heart rate. It uses photoelectric sensors to detect the difference in reflected light intensity after absorption by human blood and tissue, and trace the changes in blood vessel volume during the cardiac cycle. Heart rate is calculated from the obtained pulse waveform. When the watch shakes, the received light intensity will be affected by the shaking, which will affect the recognition accuracy. Accuracy.
