Bmaidman , via OnePlus 6T , Nov 7, 2019 : I am having an issue with my mi band 4 and my 6t when exercising. when I run and complete one 1 mile i doesn't properly display the correct lap pace. for example if I run a ten minute mile it might say 15 min on the band. the number of minutes it's off by fluctuate so it is not a matter of doing simple math in my head. it is however usually around 6 min off and always greater then my actual time. I have tried multiple mi band 4 on my phone so the band itself can be ruled out. does anybody else have this problem?
