Charge 3 not registering active minutes

[AngelaMWil]

Hi, I have done my regular two workouts today which would normally register as 67 active minutes. However my App is showing 0 active minutes.

Of these minutes, 37 minutes was cardio, 30 were peak and my heart rate reached 162 bpm. I burned 507 calories which have not been added to my calorie count. My steps have been added and sync is showing as complete. 

I have uninstalled and reinstalled and turned my phone off and on again but nothing changes. Any ideas please?

Welcome to the Community, @AngelaMWil.

Thanks for troubleshooting this accuracy issue. Our algorithms detect subtle differences in exertion that may explain why two seemingly identical activities result in different active minute totals. For example if you took a brisk walk along the same route two days in a row, differences in your speed and exertion levels (e.g. out of breath vs not out of breath, etc) will cause different active minute totals for the two activities. Also keep in mind that active minutes are only recorded for activities that last 10 minutes or longer. 

Because our trackers primarily track movement through the use of an accelerometer, they more accurately detect active minutes for step-based activities (brisk walking, running) than non-step based activities or activities that require more than steps (yoga, tennis). Trackers with a heart rate monitor detect active minutes most accurately, since heart rate data allows us to better estimate caloric burn and, in turn, exercise intensity.

For more information check the article: Why did I earn a different number of active minutes for the same activity?.

Let me know the outcome.
