I just upgraded from a Charge 4 to a Charge 5. One of the reasons I did so was that the HR readings during exercise always took about ten to twenty minutes to 'catch up' to what I was doing. Unfortunately, the Charge 5 seems worse than my old Charge was. I know enough about my HR readings to know that it is totally off and not capturing what I am doing. I have seen this is a common complaint and have done all the reset and tips; it still doesn't work. I am wondering if anyone with the same issue has changed their Charge 5 for a different model that works better/more reliably?
