Even my old Versa, I only charge it about every 2 weeks. It tells me the battery is getting low at 30%, then I know I have a few more days to plan a decent charge when I'm neither active nor sleeping.
Funny thing about the sleep function, if I sit too long at my computer reading (emails, reports, news articles) it will record it as a sleep period. "When did I sleep 9 hours last night? Ohhh, 2.5 hours while at work"
