ASUS Transformer Pad 300 Review

Battery Life testing

In an attempt to quantitatively measure the Transformer Pad 300's 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.

Untethered Up-Time Measurements

For this test, we set the Pad 300's display to 50% brightness, which is still plenty bright and easy on the eyes. We ran the test in Balanced modes, but note that in Power Saver mode, in which you'd still get plenty of performance for simple web browsing, you could expect longer up time. In Performance mode, of course, battery life would disappear more quickly.

Well, we suppose the battery performance could be worse. The Transformer Pad 300 did better than the Prime, but it didn't come close to the original Transformer, the Galaxy Tab 10.1, or the IdeaPad K1. Granted, the Pad 300 is running a more powerful quad-core processor, but it's disappointing to see that it falls so far short of its rated battery life. With the dock supplementing the tablet's battery, the overall battery life is much better--over ten hours.
