It says:"Battery life: Up to 10 hours and 15 minutes (mixed usage), up to 6 hours and 30 minutes (video playback), up to 8 hours and 30 minutes (wireless streaming)"Actual usage is closer to 3 hours of just using wireless and internet.  That's it.  Was purchased for my daughters for their online school.  Now I regret it since they constantly have to charge the battery.
