I think I saw it here, but somebody had a pretty solid system for sleep tracking/making use of the silent alarms, which I've taken to using. Basically, you charge it twice per day, while you shower/brush/floss/eat in the morning and in the evening - basically, pop it off for an hour or so where you don't really need it and charge it then. It recharges really quickly, especially at lower battery levels.
