Re: Game playing on nexus 7
Welcome to Android Central! Playing games will generally use more battery than watching videos, because there are probably more processes going on with the game (e.g., animation, touch registering, increased bursts of CPU processing depending on the complexity of the game). With video playing, there's just the one process of video playback that's going on. That's why the video playback time reported by manufacturers (and corroborated by reviewers) is usually longer than the actual battery life with real world use--with video playback time, they just play a video and leave the tablet alone until the battery runs out, without disturbing it or switching between apps.
