HRV accuracy in charge 5

[Hpmiller1]

Has anyone else had issues with the charge 5 not registering HRV at night correctly? Mine is consistently pretty low and on a couple of occasions has been at a 12! I have no history of heart issues and am an active and healthy mom at 31 years old. Just wondering as the results have been having me concerned but I'm thinking it's probably just the watch not being accurate in this....

My past 2 replacement charge 5s have not tracked an accurate heart rate for me during workouts. I haven’t experienced problems while sleeping.

I only get a HRV once or twice a week at most. Way back in December I used to received it daily, No rhyme or reason why it stopped other then I think that was around the time we had to install the charge 5 firmware upgrade. (and about the time my Fitbit warranty expired)

Hi @jaybee8955 @Jazlyna it's nice to see you around. Welcome to the community forums @Hpmiller1. 

Thank you sharing this information about what you've been experiencing with your Charge 5. 

Please keep in mind the following to make sure you see your health metrics data:

• Wear your device for at least 1 full day (during the day and to sleep at night). Check your stats after you wake up in the morning. Note: skin temperature requires 3 nights of data.
• Make sure the back of your device is in contact with your skin. The band should be snug but not constricting. If you experience any discomfort, loosen the band, and if it persists give your wrist a break by taking it off.
• Most metrics require at least 3 hours of quality sleep. If you move a lot during your sleep or the sleep session is too short, you might not get a reading.

For more detailed information, see What should I know about health metrics in the Fitbit app? In case the HRV is being tracked but it's not being shown in the app, please try the following steps as well: 

1. Log out from the Fitbit app.
2. Clear Cache and Cookies for the Fitbit app on the phone's settings. 
3. Restart your phone. 
4. Log back in and check if you're able to see your information properly.
