Heart rate inaccurate Charge 5

[Fireangel117]

I find when I am walking/moving the Charge 5 measures my heart rate as much higher than it actually is, by quite a lot. It will say my heart rate is 150 while walking, but as soon as I stop moving the watch will pick it up accurately in the 90s. It's like it's sensing my arm movement rather than my heart rate. Frustrating!

Hi, welcome to the Fitbit Community forums, @Fireangel117.  

Thank you for sharing this information about the inconvenience you've been experiencing with your Charge 5. 

Before considering other options, there are some general recommendations that are usually helpful with this type of issues with heart rate. If you haven't done so already, I recommend that you try restarting the device using the three pulse restart method mentioned here below, instead of the restart option found on the Charge 5 itself: 

1. Connect your device to the charging cable. For instructions, see How do I charge my Fitbit device?
2. Press the button located on the flat end of the charger 3 times (end of the USB cable), pausing for 1 second between presses. Then wait 10 seconds or until the Fitbit logo appears.

In addition, please follow the instructions in this article to improve the accuracy of heart rate information and check the information mentioned here about other factors that could affect your heart rate reading, this has been useful to other users who have experienced something similar. 

Hope this helps, I'll be around.
