Yes, it's fully charged when it says 100%, despite the message on your Versa that it'still being charged. I personally never saw the message "Charging Completed". When you put your Versa on your wrist again, it will very fast drop to 99%, but do not worry, my Versa lasts 5+ days on one charge with the same notifications!!
Best AnswerCheers buddy , my charge last week lasted 7 days and that's because I have a few things turned off like heart best ect other wise it lasts around the 5 /6 days
