It was stated that “Fitbit has also brought its Smart Wake feature to the Charge 4; the company says it uses machine learning to know the best time to rouse you from your slumber, a feature my toddler has perfected without the assistance of advanced algorithms.”
However, this feature is not available yet (at least it is not on the charge 4 I just got and per the fitbit forums). How was Tom’s Guide able to get access to this feature to test it?
