A:Answer It all depends. A full charge and not using it, it will last several days. If you put it in sleep mode instead of shutting it down, the battery will discharge more quickly.
I charged mine 2 evenings ago, have used it for a few hours, left it in sleep mode while I ate lunch and I still have 27% (1 hr. 33 mins.) left. I think the battery is rated at 5-6 hours, so mine is right on schedule.
