Samsung Galaxy Tab 2 10-inch and 7-inch Review

Battery Life

In an attempt to quantitatively measure the battery life of the Galaxy Tab 2 7.0 and 10.1 tablets 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 displays on the Galaxy Tab 2 7.0 and Galaxy Tab 2 10.1 to 50% brightness, which is still plenty bright and easy on the eyes. In our test, the Galaxy Tab 2 7.0 lasted for seven hours and 45 minutes before shutting down. The Galaxy Tab 2 10.1 lasted for nine hours and 24 minutes before shutting down. It's worth noting that the Galaxy Tab 2 10.1 came in second in our battery life test, with only the Asus Transformer Pad 300 in its docked state beating out the tablet. That's actually pretty impressive.
