my laptop is asus and his battery is built in when i need to play game should i plug it (charge) to play?

Solution
when playing video games your system needs full power to CPU and video card.
when not plugged into wall, your on battery save mode, which means CPU variable power and GPU Variable power to save as best they can energy.

when playing games (not Facebook games here, real games) and while on battery, then expect the battery to last maybe end up 1/3 time expected to last normally as cpu and video card will eat up power like candy

I recommend to plug in wall. when playing video games
