Samsung Galaxy Tab 2 10.1

In addition to its powerful front-facing speakers and bright screen, we loved the Galaxy Tab 2 10.1's epic battery life. Sure, it may charge slowly, but when you finally have a full battery the Galaxy Tab 2 10.1 will last you almost all day. On our tests, the tablet lasted a whopping 9 hours and 59 minutes. You won't find better battery life on an Android device.
