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 did the above hike with Fenix 6 Sapphire with 4.20 software version (used the "Hike" exercise mode).

    I was going uphill on the mountain for 30 minutes, so exchausted I barely could talk throughout the exercise, still the chart claims my HR suddenly (in middle of climbing the hill) dropped from ~150 to <100 and magically stayed there.

    As I noticed this during the exercise, I even tried to press the watch hard against my skin with the other hand but it wouldn't help to jump back to the "real HR levels".

    Let's hope there is a working fix in the pipeline as they indicated in the sensor hub beta v2.53 thread.. This is really annoying bug. My old Vivoactive 3 was spot on with HR every time.. I would expect no less from the Fenix line.
