My battery drains about 15-18% every half hour when playing this game, is that normal? This is not a 3D game so I didn't think it'd be that demanding. Responses from people who have played the game also would be appreciated.
Welcome to the forums
Even though it isn't a 3D game, you are still using video, sound, the processor (probably a lot more than you realize), and constantly touching the screen, and obviously the kernel. All those things can attribute to battery drain.
OK well at that rate I'd only be getting about 3 hours of onscreen time, which is less than what reviews have stated. Anandtech for example, reported getting 4 hours in their 3D game battery test.
