winbook W, reviewed on cnet gets 3 hrs 50 min (mitac 8060B?)
How they test for batt life:
"MobileMark 2002 is an applications-based benchmark that measures both application performance and battery life simultaneously. CNET Labs uses the benchmark's Productivity workload when running MobileMark.
The benchmark runs the following applications: Microsoft Word 2002, Microsoft Excel 2002, Microsoft PowerPoint 2002, Microsoft Outlook 2002, Netscape Communicator (Mozilla 5), McAfee VirusScan 5.13, WinZip 8.0, Macromedia Flash 5.0, and Adobe Photoshop 6.0.1. ..."
blah blah blah
"...The MobileMark 2002 battery rating, expressed in minutes, reflects how long a notebook with a fully charged battery is able to run the MobileMark test. The test concludes when the battery is drained.
A note about CPU throttling: As per BAPCo's recommendations, CNET Labs runs MobileMark 2002 using the Portable/Laptop power scheme. This power scheme allows a notebook to automatically throttle down its CPU speed in order to conserve battery life. The amount of CPU throttling is dependent on a how a manufacturer has configured that particular model and can therefore vary among models from different manufacturers. This can be a contributing factor as to why some notebooks with similar specifications generate different MobileMark 2002 application and battery-life performance scores."
Specs I took off http://www.mitac-mtc.com.tw/
Mitac 8050 has a 2200 Mah 6 cell
Mitac 8080 has a 2200 Mah 8 cell
Mitac 8399 has a 2000/2200 Mah 6/8 cell
Mitac 8599 has a 2000 Mah 8 cell
Strangely, there is no link to the 8060B (the Winbook W series) spec sheet. Kind of bothers me. I would surmise from the other builds of the similar type that there is either a 6 or 8 cell in there, probably 2200 Mah. So, the Mitac 8050 should come out with pretty close to the same battery life as Cnet reviewed the Winbook W for, close to 4 hrs under a good load.
