I'm not sure if there's proof one way or the other, and I'm too stubborn to change my ways,
so I'll stick to my
nightly charging ritual (I typically want to replace my BlackBerry with the latest and greatest anyways...
so the battery always seems to outlive my use for the device!).
Most high - end wearables today need to be
charged nightly,
so the fact that I can go four to five days between
charges on the Fitbit Ionic is a major selling point.
