Power Consumption and Battery Life

We used BatterEaterPro's "Real World" option to test the Samsung R580's battery life. With it's Core i5 CPU, relatively large screen, and discreet GPU, along with a thin 6-cell battery, we weren't expecting any miracles...

Ouch. There's just no other way to put it. A 6-cell battery is pretty small to begin with when you're looking at a Core i5 notebook with a discrete CPU, and during our real-world battery drain test (which has the screen brightness set at 65% and Wi-Fi on), we only saw 1 hour and 49 minutes of life. If you were watching a DVD or otherwise using the optical drive, you'd see even less. If you were gaming, we suspect you'd see even less.

There's the possibility that the life could be extended to 2 or 2.5 hours in a pinch, but this is in no way a true road warrior's machine. The battery life proves that Samsung expects you to keep the R580 near a power outlet most of the time; you might as well consider this a desktop replacement in terms of battery life. But at least you can buy a spare 6-cell or two and swap them out if need be.
