My Garmin Fenix 8 amoled 47mm has reliably recorded heart rate data since its purchase, until December 2025.
From that point on, no heart rate data shows up on the Garmin Connect portable (iPhone) or laptop (MacBook Pro) versions, Strava or any other third part apps I use to analyse my running data. The watch fit has not changed.
Having looked at this and other user forums, I tried the following:
- Switching off the watch
- Garmin software update
- Checking wrist heart rate was on auto
- Checking HR lights flash
- Using other watch bands
- Using an external Polar H10 heart rate monitor, which worked twice then stopped
- Interestingly, when I go into the Run option set up, wrist heart rate is permanently off and will not go back on after button press.
- Also, my Stryd footpad has stopped feeding data.
- I checked with Polar 10 HRM and Stryd pod in combination, Polar H10 only, Styd pod only and neither. None of these versions give me a heart rate signal.
Walking and static gym work on the other hand, do give me a heart rate signal and recording.
My first thought was this is a software issue, since it coincides with a software update that put the Garmin IQ symbol on my active run watch face. However, it is starting to look as if it may be hardware bandwidth.
I'd appreciate advice on how to get my wrist heart rate signal dn Stryd pod recording again.
