Lenovo Legion Y740 Review: Battery Life, Acoustics And Thermals
Battery Life - How We Test:
Our custom HotHardware video loop test takes a 1080p HD video with a 16Kbps bit rate and loops it repeatedly, with 1 minute break intervals in between. A timer log file increments minutes of up-time, every minute -- along with the grand total -- before system shutdown is stored and logged. This is a lighter-duty test that is still a bit more strenuous than many office productivity tasks. During the test, we keep Windows 10 Quiet Hours enabled and the display has been calibrated with a meter on pure white screens to as close to 115 lux as possible. For the average laptop this is somewhere between a 40 - 60% brightness setting. Because laptop 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. And, since many laptop displays vary in brightness at each respective setting in Windows, this calibration with a meter is critical to ensure all displays are set to as near identical brightness output as possible, before running battery tests.
