I know I'll never be able to achieve 8-9 hours, but I was hoping for at least 7 or thereabouts. Unfortunately, I only managed a paltry 5 hours on my first two 'complete' discharges. This is with airport and bluetooth on, screen at half brightness and running windows 7 in parallels in addition to the usual browser/office stuff. Is there something I can do to improve battery life? Or is having parallels running all the time draining the battery extra fast? Also, is there some sort of battery monitoring utility that can accurately detect what exactly the battery is doing? I find the default one to be somewhat sparse in terms of details.
