Question Hearth rate inaccurate while cycling

[koostamas]

I can't get the band to measure my heart rate correctly while cycling. I tried with endomondo and mi fit apps on separate occasions. The endomondo app measured 81 bpm the whole time while the mi fit app's measurements can be seen below:

This data is clearly not correct, which is odd, because the band seems to measure the correct rate in every other situation during my day (sitting, walking and sleeping). I tried 3 different positions with the band, left hand as the app suggests, left hand under side, right hand.
Is there something I can do to make the band measure my heart rate more accurately while cycling?
Has anybody else bumped into this weird behavior?

i"m experiencing exactly the same with my band recently. i think it measures around 20bpm more for me during cycling. this wasnt like this at first so it might have to do with recent firmware updates.
what mi fit version and firmware are you using?
