Buying a new Fitbit Charge 3? Bad news for those that like having spares, the Fitbit Charge 3 charger utilizes a new cable that's not compatible with the previous gen model.

For this Fitbit Versa 3 review period, I got about 3.5 days of power. I took the watch off the charger at 8:00 AM on Monday, and it was at 7% by 4:00 PM on Thursday.
