Troubleshooting Redmi Watch 2 lite
1.Q：What should I do if my Redmi Watch 2 Lite doesn't count my steps?
A：Step recording principle: the watch has a built-in acceleration sensor, and the data detected by the acceleration sensor is then combined with the algorithm and the basic information of the human body, which is finally transformed into information such as step count and consumption.
Factors that affect the number of steps recorded by the watch.
1. Because the principle of the watch to measure walking distance is based on the user's own set height, gender and weight so as to estimate the user's step length, and then multiplied by the number of steps taken by the individual to arrive at an estimated value.
2. Because the step length itself will vary from person to person, may be the same height, gender, weight of the person's step length will be different, so the final calculated value will also have a large error.
3.The accuracy of the pedometer, that is, the number of steps taken, there are many uncertainties will have a lot to do with each person's behavior, such as the amplitude of arm waving walking habits and human activity activities more scenes (such as walking, car, driving, bathing, etc.), arm movements are more complex (such as keyboard tapping, moving the mouse, lifting and pulling objects, etc.).
4. It is because of the above reasons that the final distance calculated by the watch is an estimated value, and the watch cannot be used as a professional measurement tool to measure distance. We will continue to optimize the software algorithm so as to calculate a more accurate data.
2.Q：Why is GPS positioning sometimes slow?
A：GPS start-up is divided into cold start, warm start and hot start. Cold start generally occurs in the following situations.
1、When the watch GPS function is used for the first time.
2、Watch battery power exhaustion shutdown causes satellite ephemeris information loss;
3、When the displacement of the watch is more than 200km in the shutdown state
Since the watch GPS positioning system needs to download the satellite ephemeris information in the cold start state, its positioning time will be much longer than that of warm start and hot start.
The positioning time will be much longer than that of warm start and hot start. Considering the influence of the way the watch is worn and the arm on the GPS antenna, during cold start (including the first positioning), it is recommended that users choose an open field and keep the dial pointing to the sky when the watch is worn normally, so that the ephemeris download and GPS cold start positioning can be completed within 60 to 90 seconds, and the specific positioning time is related to the weather and the surrounding environment.
If the watch has not been displaced too much after the last positioning and the interval between the last positioning and the last positioning is less than 2 hours, the watch GPS can achieve hot start. In an open field, the watch can be positioned in about 5 seconds when it is worn normally and the dial is pointing to the sky. The specific time is related to the weather and the surrounding environment.
When you encounter slow GPS positioning, you can reopen the APP and reconnect the watch to synchronize data, which will also greatly improve the GPS positioning speed.
3.Q：Why sometimes, there is no motion track or the track is lost after the movement?
A： 1. Before the start of the campaign please check to confirm that the GPS positioning is successful in the campaign preparation interface (i.e. the GPS symbol turns blue and there is a vibration prompt) before starting the campaign.
(1) GPS is subject to many factors, the surrounding tall buildings, complex terrain, flyovers, tunnels and complex electrical signal environment, harsh climatic conditions such as sandstorms, heavy rain, and other bad natural weather can cause GPS positioning failure, motion track loss, etc.
(2) In order to ensure that the GPS track is more accurate, it is recommended to keep the phone and watch connected when opening the campaign, and during the campaign.
4.Q：Why does the motion track drift?
A：GPS drift refers to the gap between GPS positioning and the actual position, and the continuous trajectory with a certain interval between the actual route in the movement. There are many factors affecting the GPS, such as the surrounding tall buildings, complex terrain and complex electrical signal environment, bad weather conditions such as sandstorm, heavy rain, and other bad natural weather.
5.Q：Why is no motion data generated after exercise?
A：1. Please confirm whether the watch is normally kept on and whether the heart rate is normal.
2. Whether the exercise time or distance reaches the minimum standard of exercise record after the exercise is turned on.
3. It is possible that the heart rate is not properly monitored caused by improper wearing.
6.Q：Why does the watch still display the speed information even after I stop exercising in sports mode?
A：The mileage and pace during exercise are determined by time calculation, and the pace does not stop until 10 seconds after the exercise is stopped.
7.Q：What if the Redmi Watch 2 Lite won't charge?
A：Please follow the following methods to troubleshoot or check.
1. recommend using a regular standard charging head for charging.
2. check whether the metal contacts of the watch body and the metal contacts of the charging cable are stained, try to wipe them with tissue paper, etc., (if rust appears, use a cotton swab or cotton cloth with alcohol to wipe) to ensure that the watch body and the charging cable do not have poor contact.
3. Take the watch off the charging stand and put it back, re-plug it and try to replace the socket.
If the above check is invalid, you can apply for after-sales testing.
8.Q：Why does Redmi Watch 2 Lite show heart rate when worn on other objects?
A： The watch is designed to analyze an individual's heart rate by collecting signals from an optical sensor. Due to the limitation of the sensor working principle itself, if the watch is worn on other objects or when there is an obstruction in front of the heart rate sensor, the heart rate value may be measured if the heart rate sensor monitors the change of light signal, so when the algorithm is compatible with the former signal, it will misjudge the latter signal and lead to the calculation of the heart rate value.
9.Q：Why can only a small number of dials be stored on the watch?
