What tuning did you do on Vista prior to your measurements? A
stock Vista install never actually goes idle, so it eats the
battery life.
With FreeBSD if you run X with an alpha-blending WM and a
background process to continually keep the CPU 10-20% loaded and
the disk active, you also get poor battery life.
Vista, when properly tuned, will get better battery life than Vista
because it can also turn off devices to save power. FreeBSD lacks
the ability to power down USB, wireless and wired net devices,
CD/DVD drives, etc.
