In an attempt to quantitatively measure the A700's battery life in a controlled benchmark environment, we ran a test in which we set up a webpage with a mix of graphics, Flash media and text. The page automatically refreshes every three minutes, we loop the page and also setup a screen lock utility that keeps the display from sleeping during the test. Battery life is measured down to the minute the tablet finally shuts down. The Wi-Fi radio is enabled in this test to simulate battery life in real-world web browsing over a wireless connection. The stock browser was used.
For this test, we set the A700's display to 50% brightness, which is still plenty bright and easy on the eyes. The A700 lasted seven hours and 40 minutes untethered before it powered down, which places it right about in the middle of the pack.
