Razer Blade 2017: Battery Life

In the following benchmarks we employ two very different battery life tests -- Battery Eater Pro and a custom 1080p HD video loop test -- to prove out battery life with our test group of machines and the Razer Blade. In all tests, Windows 10 Quiet Hours have been enabled and displays are calibrated with light meters on pure white screens to as close to 115 lux (on the meter) as possible. For the average notebook this is somewhere between a 45 - 60% brightness setting.

Since notebook displays significantly affect power consumption and battery life, it's important to ensure a level playing field with respect to brightness of the display for battery testing. However, since many notebook displays vary in brightness at each respective brightness setting in Windows, this calibration with the meter is also critical to ensure all displays are set to as near identical brightness as possible before testing.

Battery Eater Pro provides a heavy load on the laptop and generally runs through its battery life much faster than our custom video loop test. Our video benchmark helps you get a sense of how long the laptop will handle ordinary tasks while on battery power; Battery Eater Pro presents a worst-case scenario.

Our battery benchmarks seemingly tell a tale of two laptops, but there is good reason for it. When in all out assault mode - as in Battery Eater - the GeForce GTX 1060 consumes a good bit of juice. Then, when the laptop is performing more casual tasks - like video playback - the GPU is disengaged and the processor is able to step down which results in the stellar efficiency we see in our video loop test. That's a hair over 7 hours of video playback, by the way, which is enough for a school day or transcontinental flight.
