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?

  • I have the opposite problem. When I hop on the elliptical, the watch tells me my hr is 190 for the first 10min or so and then gradually falls down to reasonable 130-140. For those wondering what's my point, my resting hr is 47 and chest strap puts my hr at 115 for those 10min of warming up. 190bpm is calling 911 and rushing me to emergency territory. The watch is a joke really - completely useless HR measurements.

    And yes, i've already tried 2 other Sapphire 6x watches purchased from different retailers all with similar results on 4+ firmware
