The iPad 2,4 review: 32nm brings better battery life

“The gains themselves are significant. We measured a 15% increase in our web browsing battery life, a nearly 30% increase in gaming battery life and an 18% increase in video playback battery life. Although Apple hasn’t revised its battery life specs, the iPad 2,4 definitely lasts longer on a single charge than the original iPad 2.” For the same $399 price (but no way to know beforehand which model you’re getting). Alternative headline: why Apple owns the tablet space.
