Heart rate and calories issues-Charge 3

[FallGuy]

Hello all. I've had my Charge 3 for about 2 years and all of sudden it lost its mind.

Just sitting on my recliner, it shows my heart rate anywhere between 120-175 BPM. I have a finger pulse/ox unit and a blood pressure cuff registering anywhere from 68-74 BPM.

Also, the Charge 3 says I've burned 11,287 calories so far today - quite impossible since my leg is in a cast. I've done every reset I can find on this site and nothing seems to help. Should I just bite the bullet and buy a new one?

Welcome to the Fitbit Community, @FallGuy.

I’m sorry to hear about the issues you experienced with your Fitbit Charge 3. Thank you for the information provided.

There are some factors that can affect your heart-rate reading on your Fitbit device. Please follow these tips to resolve heart-rate tracking issues. 

If you manually logged activities or if you have connected your Fitbit account with a third party app (Strava, MyFitnessPal, etc), the information registered by them can increase your calories burned.

For information on how your calories burned are calculated, please visit this article and open the menu "How does my Fitbit device calculate calories burned?". In addition, please make sure your weight and height information is accurate. For instructions, please visit this article.

Hope this helps.

Same exact thing is happening with mine too. I’ve had it for about 2 yrs and it just started going crazy. I’ve rebooted multiple times and it is still going crazy, particularly the heart rate sensors. I’m frustrated because the same thing happened to my first FitBit, the Alta Hr after about 2 years too.

Whether you haven't done so, please perform a long restart to your Fitbit Charge 3:

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again.
