As far as battery life goes, the G501 lasted for a middling 3 hours and 6 minutes on the PCMark8 benchmark test. This places it in the middle of the other two laptops; with the P35K v3 clocking out after 3 hours 33 mins. The Blade, meanwhile, falls short of the three hour mark by a full 29 minutes.
Even with a basic round of everyday tasks including running Skype, Spotify, Chrome, plus a handful of Hearthstone games while the screen was set to its maximum brightness, the Asus ROG G501 only lasted for 30 minutes more. By comparison, the Gigabyte P35K v3 ran for a very similar 3 hours and 40 minutes. The Razer Blade tails closely with 3 hours and 43 minutes of battery life.
