I got a message on my computer saying my battery in my fitbit was low and I should put it on the charger. When I put it on, it registered a full charge.
While I was on vacation recently I got 10,000 steps each day. Since it didn't kill me or put me in the hospital, I decided to change my New Year's Resolution from 5,000 steps per day to 10,000 steps per day. I haven't managed it every day, but I have 9,500 average for the last seven days.
