I've had a Charge 4 since Sept.  For about 6 months it worked well.  HR accurate ( I have two other HR monitors to judge by).  Sync was fine.  Then I didn't use it for about two months or so and am coming back to using it.  First, I had a heck of a time getting it to sync again.  That finally resolved and this morning I noticed the exercise HR was really far off.  Like I was in full on cardio mode at 140 - 150 bpm per my other trackers and only 55 - 60 with fit bit? It didn't seem to matter where I placed the watch face (inside of wrist vs outside).  I tried resetting and still very inaccurate.  My resting HR seems accurate.  

AModerator edit: clarified subject.ny fixes for this?  I don't want to have to wear an entirely separate device every time I work out just to get an accurate HR.

Welcome to the forums @deefromlv.

Thanks for the details regarding the inconvenience with your Charge 4.

I recommend that you try restarting the device.

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.
