Charge 6 - Heart rate readings

[psantarelli1]

I recently converted to a 6 but notice a big difference in heart rates during exercise. Much lower. My workouts with Charge 5 were consistently in the moderate to higher range. Now same workout but rarely in higher ranges. I’m still feeling it. 
what’s up?

Hi @psantarelli1 and welcome to the forums.

Hi @psantarelli1 and welcome back! 

I appreciate your message. Please allow me to expand on the information provided above and give you more details about heart rate readings.

Your Fitbit's heart rate readings might not always match those from other devices, like chest straps or other wrist trackers due to the differences in technologies.

Differences between heart rate readings on your device and on exercise equipment may also be due to wrist or hand position. Make sure the back of your device is in contact with your wrist and that your band is snug.

You might also notice variations between your heart rate reading on new Fitbit devices compared with your old ones due to changes in the heart rate sensor or algorithm.
