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.
The test is run once with the computer's Power Options set to Balanced. You'll notice our graph has been cleared. PowerMark was updated to the latest version for testing, so we removed the test results created with the past version.
Haswell clearly takes the Acer Aspire S7-392 to a whole new level in terms of battery life. It's the only system to break into the 4-hour runtime category, which is nearly double that of the older S7-391.
