My Charge would not determine my HR at all for a few days last week. I adjusted the position on my wrist, took it apart and cleaned it, and I eventually let the battery die and did a full charge on it (had been a while). After I charged it up fully, it has now been overshooting my HR. I have taken my HR by myself and it has been around 70-75, but my Fitbit is saying 100-105 at that same point in time. My normal resting is around 65-70. One day it even gave me 600+ active minutes based on elevated HR, although I had really only done about one hour of activity that day. It also said I burned 9,000+ calories that day, despite only 3.5 miles and 7,000 steps. Although it is determining a HR, I'm still getting simplified sleep results too (as opposed to seeing my sleep stages as I normally would with my HR).
