Benchmarks - Battery Life, Audio and Video Encoding
The ViewSonic ViewBook Pro will go through my standard test regime consisting of iTunes encoding, movie encoding and Battery Eater Pro. I will start with iTunes Encoding.
For the iTunes encoding test I take the Stone Temple Pilots Core CD in MP3 format and encode it to AAC format using iTunes and time the results with a stopwatch. The ViewSonic ViewBook Pro turned in a good performance result in this benchmark considering how thin the machine is and that it uses a ULV CPU. Check out the chart below for all the details.
Windows Media Encoder
Version and / or Patch Used: 9

For the movie encoding test I take the HD Microsoft Magic of Flight video and encode it to DVD quality video with CD quality audio using Windows Media Encoder. The ViewSonic ViewBook Pro did well in the movie encoding benchmark; it is very powerful for its class.
Battery Eater Pro
Battery Eater Pro is very hard on batteries so you are likely to get more run time in the real world, depending on how you use the machine. Since the ViewSonic ViewBook Pro is the first machine I have tested that has two batteries, I am testing this machine a bit differently.
I turned off all power saving features of the notebook and the high performance score will be with the screen at 100% brightness and only the main battery installed. The power saver test will be run with the screen at 100% and both the primary and secondary battery installed.
Battery life for the machine was decent with just the main battery; the extra battery just ads icing to the cake. Check out the chart below for the results.
