Versa 4 is tracking my heart rate too low

[Angtennis]

My Versa 4 is tracking my heart rate way too low. During weight training, I was above 100 the whole time and it was measuring in the sixties. Or sometimes it will be low during an exercise and then jump up to the correct number in the middle. As a result calories are incorrect. Or the caloric count will be inaccurate for the average heart rate. Average heart rate of 106 for an 80 minute bike ride came up as 235 total calories. It should be close to 400. Chatted and then called customer service and both were unhelpful and then I was disconnected.

Hi there, @Angtennis. Welcome to the Fitbit Community Forums. 

Please note that several factors can affect resting heart rate: stress, alcohol or caffeine intake, or fever usually raise resting heart rate, while regular exercise or meditation can lower it. Air temperature and certain medications can also affect resting heart rate. For more information, see What factors can affect my heart-rate reading on my Fitbit device? 

Even though I truly appreciate you took the time to come here and express your feelings towards your experience with your Versa 4 and also want to find a resolution to your issue, my best advice is to keep the conversation with our Support Team. Since you already contacted them, it's easier to continue working with them.

I tried chatting with Princess. After 15 minutes, she still couldn’t figure out how to verify my identity, and then disconnected the chat. So, I called customer service. After 22 minutes of verifying and explaining, he was in the process of checking the statistics I told him about. Then he disconnected me and did not call back. I am extremely dissatisfied with the Fitbit support team.
