Charge 3 doesn't count all my active minutes

[Panporan]

For some reason, tracked exercise doesn't count toward active minutes. At least not all of it. Sometimes it seems to count some of the minutes, but not all. Is my fitbit broken??

Welcome to the Community Forums @Panporan. We're sorry for the late response, due to recent events affecting our operations, we're taking longer to respond.

Thanks for the details provided about how your Charge 3 has been tracking your active minutes. I'll be glad to help you with your inquiry.

Note that the 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. 

Because the Charge 3 primarily tracks movement through the use of an accelerometer, it is 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 like the Charge 3, 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. 

Also note that if you're manually logging activities, your Charge 3 uses a standard MET score and your (optional for custom activities) calorie burn to calculate active minutes. Said that, high calorie burn activities will give you active minutes. Therefore, since custom activities don't include a MET score associated, you'll only get active minutes for those activities if you also log a high calorie burn. 

If you are working out in a max, and not getting active minutes, as said before, the intensity is necessary to get the active minutes, I suggest you to restart your Charge 3 and to take a look at this article: Active Minutes.

I hope this helps you, let me know if you need further assistance.

That all sounds very complicated. But something seems broken with my fitbit charge 3. I did 172 minutes fatburn, but it only counts as 18 minutes. I did not used to be like this! It is the same when I do cardio, but I would have to find another screen of this. please see my screenshot below. It may be a moot point now, though, as I just purchased a fitbit charge 4 . . .
