Best Battery Life: Apple iPad and iPad mini
Gauging battery life for tablets, laptops and other devices is a crapshoot. Tablet makers often inflate battery life claims, while reviewers use differing techniques to test battery longevity, making apples-to-apples comparisons difficult. That said, Apple's iPad has always had a strong history of long battery life, with some reviewers finding that the full-sized and mini iPads exceed Apple's 10-hour claim. Worth noting, however, are Macworld tests showing that the fourth-generation iPad battery doesn't last as long as the second- and third-generation iPad models.
