Anyone STILL having heart rate accuracy issues with their Fenix 6?

Hi all,

Super frustrated, but I am still having issues with my Fenix 6S and heart rate accuracy even with the 4.20 software update. I'm wondering if it's just me or what the deal is? I had a 5S Plus before this and had no issues doing the same activities so I really don't think it's user error. My heart rate hardly reads over 110 during really vigorous exercise when my heart rate is closer to 160+. I have tried wearing on the inside of my wrist, tried my other wrist with no luck. It consistently reads 80-110 bpm the whole time. I wouldn't have bothered to upgrade if I knew this was going to be an issue. I know that wearing a chest strap is the most accurate, but I don't like to have to wear it for all of my work outs and my old Fenix was totally fine as well as my apple watch before that. Any suggestions?

    *** it works for most people. The wrist will mold around the watch after 24/7/365 :) .

    This is a bug, as compared to Fenix 3hr (for me for instance) the f6x is not keeping up or accurate. It's just Garmins nature to release something half baked and have it working as advertised a year later. Speaking from experience with vivoactive hr, vivoactive 2 and Fenix 3hr. Garmin is running a fund me program (in the sense of releasing unstable devices and fixing as time progresses) ahahahah

    Maybe we have high expectations of quality for our money and should lower it. 1k is pennies these days anyway am I right? Garmin just following gaming industry business practice. Cheeper to fix after release vs before release (my joke on fund me).

    Very disappointing... anyway, I would like to get some help to figure out what to do immediately because I am not willing to wait months to have a bug fixed, considering I have paid 1k for this product... Their customer service do not even answer emails anymore.

    Yes, having issues in a number of activities. Heart rate seems fine if not tracking an activity but way off when in hike or climb mode.

    I have still the same issue

    @GARMIN What’s the timeline for the HR fix? Have owned the Fenix 3 HR, Fenix 5X and Fenix 5X Plus, none had broken HR sensors out of the box.

    Put one of those watches on along with the Fenix 6 series and start doing jumping jacks or burpees, 2) Watch the Fenix 6X Pro Solar cap out HR while any previous model elevates readings appropriately.

    A concrete timeline on the fix would go along way to addressing these issues.

    For all you people who keep telling us that you always had better results from older model watches - show us the evidence. My experience with the 935 and F5+, F5S and new F6, 845 and Marq is that there have been significant improvements across the board. As accurate as a strap? For me the jury is still out on that but more often than not i believe my results are close enough the majority of the time. 

    I’m sure there are hardware issues with some watches. However, the main problem is the technology. And you can be sure, the next ‘fix’Garmin provides for WHR will break it for some of those for whom it worked before. All they are doing is trying to improve the algorithm used to detect that change in wavelength that happens when a pulse of blood passes beneath the skin.

    The next hardware iteration will come out with the next version of the watch.

    So I’ll say again, show us the evidence honestly. Not just the rare occasion when it worked, but the majority of times when it didn’t.
