Rounding out our testing, we ran MobileMark 2007 to assess the notebook's overall battery life while running a series of applications through a testing script.
We are using the standard benchmark settings from Bapco, along with a few other minor system tweaks. The screensaver was disabled and the volume was set at approximately 20%.
MobileMark 2007 utilizes the following applications
* Adobe Acrobat Reader 7.0
* Adobe Illustrator CS2
* Adobe Photoshop CS2
* Apple QuickTime 7.1
* Intervideo WinDVD 8
* Macromedia Flash 8
* Microsoft Office 2003 Pro
* Microsoft Project 2003
* Winzip 10.0
Since the ASUS U6S is significantly better equipped than most ultraportable laptops, it isn't a huge surprise that the U6S provides poor battery life for its class. However, it is still disappointing that we weren't able to get at least three hours from the U6S.
Note that 3-cell and 9-cell batteries are also available for the U6S, although they may need to be purchased separately depending on where you purchased your U6S. Battery life with the 3-cell battery is expected to be quite poor, while the 9-cell should provide over three hours of battery life.
