The battery lasts about an hour or two if you're playing an MMO like WoW. I don't know of any newer and more resource-intensive games. Anything that uses the hard drive will burn up the batteries very quickly and the machine will run much slower and lag far behind the batteries. I use it to control a 32" screen as well as a USB mouse and keyboard. and sometimes plug in a controller for gaming. I wish there were more USB ports but it says so in the specs. The export to two Monitors isn't very good. He can't handle it and is slowing down. As for batteries, I limit myself to using a real laptop screen, but it's still intense. In general, it's very comfortable. I don't make great demands on it, but it can work well with Windows 10 and I can run many programs at the same time until it runs out of batteries or needs two screens.
