Weight of 0.58 pounds, the Samsung Galaxy Tab S2 is light and thin enough to easily fit into a drawer or backpack. You can purchase the Samsung in 32GB or 64GB configurations, and micro-SD support provides storage flexibility. However, the tablet's battery life is a notable misstep in comparison with its competitors.

In Laptop's testing, a tablet scrolls through webpages at a constant brightness until the battery powers down. During this test, the S2 put up a subpar mark of 7 hours and 42 minutes. Most mainstream tablets average between 8 and 9 hours of battery life.

Elsewhere, the middling battery life of the Microsoft Surface Pro 4 is a stumble. Battery testing from our colleagues at Laptop Mag revolves around simulated web browsing at a constant brightness until the tablet powers down.

In this test, the Pro 4 only put up a mark of six hours and five minutes. While the Pro 4's specifications are more power hungry than a standard tablet, most premium tablets can still reach around nine hours of battery life. The Pro 4 features a 12.3-inch, 2736 x 1824 display that is a notable upgrade from past Surface models, which featured 2160 x 1440 displays.
