PowerMark is a benchmark produced by Futuremark that simulates different usage scenarios in order to determine battery life. It loops these different scenarios infinitely until the battery hits 15% and then gives us an estimated battery life time. For our testing, we use all four different scenarios. These are video playback, gaming, web browsing and word processing.
Tests are ran twice, once with the computer's Power Options set to Balanced and another with the computer's Power options set to High Performance.
Battery life for the Valkyrie is not too bad for a gaming machine. With 87Wh of capacity, the Valkyrie lasts for 2 hours and 28 minutes in Performance mode and 2 hours and 26 minutes in Balanced mode. The differences between Balanced and Performance in all of the test machines are really negligible.
2 hours and 28 minutes of battery life is a respectable time. Considering that most laptops just a few years ago had trouble breaking the two-hour barrier, for a gaming machine to manage more than that is impressive. Of course, your mileage may vary depending on your usage.
