Charge 3 overreacting when measuring heart rate

[RossLeahy]

Hi

last year my Charge 3 was replaced under warranty as a result of the rates it was recording when I was out walking were much too high.  I put an old Charge 2 onto my other wrist and build up suitable evidence.

I had bypass surgery in 2013 and this was behind my getting a Fitbit in the first place so over time I have a pretty good idea of how my heart reacts under different circumstances and loads.

I am now pretty sure the replacement is doing the same thing if at a lesser scale and wonder if others have noticed the same thing?

Hello @RossLeahy, welcome to the community forums! Thank you very much for the information! 

This is very odd and I would like to suggest that you perform a restart to your Charge 3. You can find the instructions here. In addition, while you may be aware of, I recommend taking a look at this help article: How do I track heart rate with my Fitbit device?

On a side note, please take into consideration 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.

See you around.
