Low HRV and body battery

Same here, HRV is still low. Doesn’t matter if I fully reset the watch and rebuild from backup.

Today updated to 20.32, see what happens...

Do NOT do the reset and restore backup because it doesn't do a thing and actually makes some things worse. There is no such thing as the analogy of fixing your C drive. 20.32 makes no difference as the fix was narrow and not related.

I did a reset Saturday morning and my artificially low body battery immediately dropped 25 points!  How is this even possible?  I did just a short walk, some yard work, and by end of day BB was down to 8!!!  Even sick I never got below 20!  I reset a 2nd time in the afternoon but no difference.  The large orange stress spikes are not normal!

In addition I went for a 4 mile run yesterday with the same stats as Tuesday and actually felt stronger. Tuesday performance was +2 to 0 at the end and yesterday -4 to -5 and one run cost me a full point of Vo2 Max.  My watch thinks I lost an incredible amount of fitness over a 5 day period. Impossible, and so much for restore!  Low HRV last night and only 40 pts of BB recovery.  This is totally pathetic!!!

This watch is now worthless for anyone that buys it for statistics and keeping track of sleep\recovery.  Wait this is what Forerunner is sold for!  I agree with a previous poster that some DEI hire as dumb as Kamala Harris is probably working on these updates.

I'm done with this...Garmin's had OHR issues during activities for over a year, and now this BB\HRV issue affects it all the time. This is a hardware issue that they keep trying to fix with software and can't.

Why is it, that only some people experience these issues?
I have no such problems.

Sleep score, RHR, BB all normal.

I have already asked myself the same question.
Only Garmin can give an answer

I've had various Forerunner for 4+ years and only started having issues this year.  It's to the point where they are no longer worth it.

It took 6 months to gain 3 points on Vo2 Max and the watch decides on 1 run to remove an entire point after a watch reset\restore.  Body Battery drops 25 points in 5 minutes after a reset. Who build stupid logic like this?

If you do a reset of the watch, the Vo2 Max model is reset on the watch. As you go for your first run, an "initial" VO2 Max is calculated using a standard formula linking your pace and your ventilation. Then, more advanced analytics are leveraged during the course of your following workouts (using neural networks) to refine your actual ventilation/pace/duration "curve". This in turn makes the VO2 Max estimate change.

When you restore the data on the watch, the history of VO2 data points is restored, but not the model, which is rebuild. Then the history of Vo2 Max data points will be also affecting what the watch ends up displaying after it reevaluates your Vo2 Max after each run because there is time-decay driven smoothing used over several weeks.

If your performance and environmental conditions didn't change, the Vo2 max will catch up to its best new estimate.

To be honset, the issue sounds very similar to issues with other forerunners: See post with the topic „V02 Max decrease from Beta 20.31“
