Intensity minutes logged incorrectly

Since a few weeks back, there is a bug in the intensity minutes calculation. When I exercise, the minutes are calculated correctly (including doubling the minutes for high intensity), but then, most of the days, it seems like the equal number of minutes is added again at the end of the day. Today I did a run for 38 minutes, and it logged 155 intensity minutes. No other vigorous exercise, as can be seen on the heart rate.

  • I have been wondering is there is an issue with the intensity miniatures too.  I cannot tell if the intensity minutes are not recording properly because the optical heart rate sensor is messed up or the calculations are messed up or what.  But since subsequent OS updates to the 265 I have noticed that the volume of intensity minutes has decreased, even though my level of workouts has not changed.

  • I have the same issue. Since the beginning of October my intensity minutes have almost dropped to nothing. I was regularly getting 200 to 400 minutes a week but since then I'm lucky to get 40. Something has gone wrong.
