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 updated sw 6.1 yesterday and did run today. Pulse was ok as I used strap but hour and half after my training when sitting on sofa, watch started to alert too high rest pulse. I thought I was going to die but when I checked with Omron M3, pulse and everything is ok. So i'm wondering also, did something broke on 6.1 update? GC shows also some weird spike on pulse at the time when alert went on.
