Battery life is just as important a parameter of a notebook as its performance. The notebook’s battery life was measured with MobileMark 2007. We disabled standby and hibernate mode for the test.
The first scenario, Productivity, emulates the user’s working in typical office applications. The load is not constant as the user is frequently distracting from his work. The second scenario measures the notebook’s battery life when the user is reading text from the screen in Adobe Reader. The third scenario is about DVD playback in InterVideo WinDVD.
Three hours of autonomous operation is a superb result, but the Dell Vostro 1400 is better than the Satellite U300-111 by an hour in every test mode. This is easy to explain. While the notebooks have similar configurations, the Dell has a larger-capacity battery.
