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.
The ASUS G1S loses this test. The notebooks have the same size of the LCD panel and the same battery capacity (4800mAh). However, the battery of the G1S is better than the M50Sv’s due to the higher operating voltage (14.8V as opposed to 11.1V). Thus, the real capacity of the batteries is 71Wh and 53Wh, respectively, but notwithstanding this advantage, the G1S is on the losing side in this test.
On the other hand, the M50Sv doesn’t last too long on its battery, either. You won’t be able to watch a full-size movie on this notebook without connecting to a wall outlet.
