The reasons for inaccurate sleep data on the Redmi Watch 5 are listed below:
1. If the watch itself does not record sleep or the detection time is less than the actual sleep time, your wrist movements are more during sleep, and the sensor determines that you are not sleeping, resulting in no record or a shorter recorded sleep time;
2. If the watch itself records more sleep than the actual sleep time, your wrist movements are less during non-sleep time and you are in a very quiet status (playing with your phone before going to bed or sitting and watching a movie, etc. will be judged as falling asleep), causing the sensor to detect it as a sleeping status.
Note:
1. Over-optimization of the algorithm will lead to missed detection and false detection of sleep. However, due to the limitation of the algorithm detection principle, similar problems exist in the industry;
2. For quiet scenes when not sleeping, the detection accuracy will be further improved with the promotion of joint detection of multiple sensors and auxiliary equipment.
