Heart Rate Not Accurate Charge 5

[Obi-Ron-Swanson]

I purchased the hr5 as i have had previous hr models.

So i have been doing interval training and my hr is getting to 170 or more but the hr5 is only showing 145-155. If the difference was 5 or 10 it wouldent bother me but possible 25 is huge really.

Is there a fix for this, I'm wearing it correctly and tested against 2 other hr monitors.

Welcome to the Fitbit Community forums, @Obi-Ron-Swanson.  

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

I saw you mentioned that you've been wearing the device  correctly; please make sure to review the steps listed 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. 

In addition, 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 settings app of the Charge 5: 

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.

Hope this helps, I'll be around.
