As with most gaming notebooks, we don’t expect the MSI GT660 to last long in our battery life test where we load our usual DVD benchmark, tweak the brightness and volume settings to the 50% mark and turn off the wireless radios. Impressively though, the MSI GT660 lasted almost two hours - 1 hour and 57 minutes to be exact - more than enough time to finish one run of our DVD movie. In this case, it beats both the Sager and Toshiba notebooks handily.
On the power consumption side of things, we noted that the notebook sips much less power than the compared gaming notebooks and kudos to MSI for an efficient implementation. Of course, it still does use more power than regular notebooks, but that's to be expected.
This is a simple test where we take the battery uptime of the notebook and divide it by the product of the unit's weight and volume. The higher the ratio, the more portable the unit is. In this case, we aren't really expecting a very portable device, seeing as how it's a notebook made for gaming with a large battery, beefy specs and a final weight of 3.5kg. As such, the low score of 0.103 don't really surprise us, though it's quite a decent score when compared against other similar gaming notebooks.
