Battery Life

In an attempt to quantitatively measure battery life in a controlled benchmark environment, we ran a test in which we set up a webpage with a mix of graphics and text. The page automatically refreshes every three minutes. This is a simple baseline test that measures up time with web browsing.

Battery Life Test
Untethered Up-Time Measurements

With the display set to 50 percent brightness, the Sony Tablet S lasted just shy of 6 hours, which is about average. Keep in mind your mileage will vary based on your usage patterns. Playing games and cranking up the screen brightness will leech battery life faster than normal.  Watching videos on the other hand, surprisingly might offer better battery life, since Nvidia's Tegra 2 SoC is generally very power-efficient in that usage scenario.
