Battery Life

Google says you should get up to 9 hours of HD video playback, 10 hours of web browsing or e-reading, and up to 300 hours of standby time from the Nexus 7's battery.

HotHardware Battery Life Test
How Long Does It Last?

In an attempt to quantitatively measure the Nexus 7'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.

For this test, we set the Nexus 7's display to 50% brightness, which is still plenty bright and easy on the eyes. The Nexus 7 lasted 7 hours untethered before it powered down.
