My wife's and my Fitbit Charge 2 can still get a good going of 5 days with a 3-4x hour-long exercise recording. My main issue with Fitbit is it treats us like someone who bought it for fashion. Also I prefer strength training, and to measure effort of anything but jogging and steps is out of scope for Fitbit. When I bought our Fitbit, I hoped the insights I can get out from the devices would improve over the years, because their slogan that time was about to revolutionise fitness with data. Unfortunately the usefulness of their products remain very basic.
