Dell Studio XPS 16 Review
Battery Performance
During our testing (shown above in minutes), we found the battery life of the machine to be somewhat underwhelming, but not embarrassingly so considering that it's a pretty massive machine that's not designed to be used for long periods of time away from an AC outlet. With performance mode enabled (meaning that the discrete GPU was activated), we squeezed out just under 1.25 hours before Vista forced itself into hibernation. With Power Saving mode activated, we were able to get just over 2 hours of life.
Mind you, this test represents "normal" activity. Light web
