Benchmarks: Power Draw and Battery Life
Considering the 8.3-million pixels on show, we're impressed to see the 4K OLED return almost eight hours of battery life in our standard video-rundown test. Heck, the OLED is only 14 minutes short of the 1080p Classic.
Looking ahead, we'll be changing our testing methodology to incorporate the new PCMark 10 Battery Profile benchmarks. Three tests will be used; Office, which intermittently uses the writing, web browsing and video conferencing workloads from the main PCMark 10 benchmark; Video, which loops a 1080p full-screen movie file for the duration; and Gaming, which uses the common Fire Strike test to stress the GPU until the battery is drained.
In order to make the results comparable between laptops, each system is configured with a balanced power plan, wireless radios disabled, and screen brightness set as close to 120cd/m2 as possible using a calibration device.
In the revised tests, battery life isn't quite good enough to get through a simulated day of office work, and it goes without saying, you won't want to be tasking the discrete GPU without a power socket nearby.
