Forerunner 965 fw 20.26 Heart Rate issues

braddulay over 1 year ago

After updating to the new software version my HR data has gone completely wonky.

Now compared with my Apple Watch it’s:

10 bpm slower at easy pace

20-30 bpm slower at tempo pace

The BPM also occasionally jumps above the apple watch for no apparent reason then goes back down below

I dont have this problems...

Did you try "Reinstall Software" ??

I do a "Reinstall Sofware" after every SW updates and solved almost all problems that I have.

I would do this... Reset watch and then update to the last SW version 22.24.

Then do a full backup of the watch... settings/sistem/backup...

Then do a "Reinstall Software"... settings/sistem/about and then press 8 times "Light" button and then chose "Reinstall Software"

Hope this will help...

it has nothing to do cleaning up the watch - the algorithm that tries to make sense missing data points from the HR sensor and sometimes (depending on how garbage the data) stuck in unrealistically low or high HR range

if you have optimal conditions (light, transparent skin, strong and thick arteries, you are not moving, there is no sunshine hitting the watch from the side, you are hydrated, did not forget to feed the dogs, etc), it works perfectly well

Same problem, my forerunner 965 is on FW v23.20. Heart rate is 30 counts lower than what's shown on apple. I have both watches on each wrist and the difference is huge
