Studies have shown that continuously monitoring a buildingâs energy systems can lead to reductions of 10 to 15 percent in annual energy bills. For the typical 50,000-square-foot retail building, thatâs equal to about $8,000 in savings per year!
Battery Life. Fitbit says the Charge HR will last about 5 days on a charge. That's about half the time of the Charge, but that endurance is reasonable considering the HR is constantly monitoring your heart rate.
I tried FitBit chat support, where the rep told me that the HR is not accurate on a treadmill - it won't record all my steps - and that I could manually log my workouts or wear my FitBit in my pocket (which clearly defeats the point of the HR).
