Sony VAIO VGN-NS30E/S - 15.4in Laptop - Battery Performance
As we can see in both the Productivity and Reader benchmarks, the processor and chipset upgrades over the NS20 result in an average of 15mins longer battery life.
A result of just less than five hours is excellent for this price-class and form factor.
In DVD playback the cheaper NS20 closes the gap, leaving its more expensive sibling with a measly five minutes of headway.
