Battery Life
Battery life is a weak spot. We would chalk this up to the device being gaming-centric in the past, but recent devices like the Aero 15x and GS65 have shown us that competent thin-and-light gaming laptops can still be marathon runners. The GU501GM lasts only 4 hours in our WiFi v1.3 test, which is a far cry from the GS65's 6 hours and the Aero 15x's 8.5 hours. This is partly due to the smaller battery in the GU501GM, which is only 55 Watt-hours. That said, the GU501GM does beat the Zephyrus M by a healthy 76 minute lead in the same test. Under load, the GU501GM only lasts 45 minutes. All said, you'll need to bring the power brick when working/gaming away from home. The device uses Nvidia's Optimus to disable the GTX 1060 under lighter loads.
