I am finding some strange results in a good way with the mi band 6. I am finding that the elevation is becoming more accurate on every cycle ride. Maybe it takes time to calibrate?
I am also finding that sleep is getting more accurate, too. It was very inaccurate when I first bought it but now is about as accurate as my mi band 4.
Finally, battery life is still terrible. I have decided to turn off auto detect for cycling, walking, running. It has not worked well for me and there have been false positives. So am hoping that when I turn it off, I will get more than 4 days of battery life.
I'm still very happy with the band. I really enjoy the auto pause and restart for sports. It is much more acculturate recording.
