According to [[User:DG|DG]], the Mi Smart Band 6 detects activity and sleep/awake well enough. Its spo2 sensor can detect holding of breath but only when not moving. Further the sensor sometimes detects smaller drops in Oxygenation for no reason and there is no options to continuously record blood oxy. He also compared the [[HR]] measures of it to the uECG and during exercise recorded data within ± 5% of the uECG. It must be worn tightly and in the right place and worst wont inform the user or record that its getting a bad signal. Moving the arm with band on while sitting still does not fool the band.

Further the sensor sometimes detects smaller drops in Oxygenation for no reason and there is no options to continuously record blood oxy. He also compared the [[HR]] measures of it to the uECG and during exercise recorded data within ± 4% of the uECG. Rarely, occasionally, its much worse.
