Stress not updating after activity, also impacting body battery

Yes, I have seen this on MARQ and previously on Fenixes too. In my case, rarely stress numbers return immediately after the activity -- and it has little to do with movement. Most of the time I might not get them for an hour and sometimes more.

Is this something that has been identified as being looked into? I browsed the forums a bit and it seems to be the case on all watches that have stress score enabled... so probably something in the general code?

The other thing I found is on body battery... when stress tracking fails (as in can't get a reading) for whatever reason except for activity (gray bars under the stress graph indicating movement), body battery will generate a flat line rather than diminish by an average as it does when not wearing the watch... I think this is a bug? HermanB?

I'm not exactly sure what's happening here, or what you are experiencing. Without looking, I seem to remember other people posting on the forum that they were having issues All-day Stress tracking not coming back on at all after an activity. If that's the case (like you mention it starts working after you restart your device), I'd just contact Garmin support directly. 

The situation that nickk describes is, probably, something different. 

Hi HermanB,

sorry I wasn’t clear in my question to you, maybe I should have posted a new thread instead.

what I meant to ask was that in case a stress measurement is not done by the watch (regardless of the garmin bug or whatever reason), body battery shows a flat line (it stays constant). Should it not continue to decrease even if no stress value (I guess that is HRV) is recorded?

I see, thanks for the clarification, no worries. 

Immediately following an episode of physical activity, especially on that involves strenuous effort, your body is in an elevated state. That state isn't 'stress' in the sense that your watch is considering it, but rather as 'recovery from exercise'. It's hard to say how long that 'recovery from exercise' state lasts, but if there is a period of time after an activity that your watch isn't reading or showing an All-day stress level in Connect, for example. then it's probably a "recovery from exercise" situation.

I'm not positive, but I suspect for the sake of simplicity ... any draining impact on your body battery during that recovery from exercise state is already factored into the activity drain rate itself.

Of course, this is quite different from a situation where stress tracking stops working after recording an activity and starts working after rebooting your device. Without any special insight, that situation sounds more like an input problem of some sort. 

Ah ok, yes I think that makes sense! 
Thank you for your reply!
