Benchmarks: Vitals and Battery Life
If there's a caveat to the two Legion 5 laptops it is that neither can be deemed quiet. Though the fans do switch off at low load, they're quick to spin into action with even the lightest loud, and ramp-up to a noise level that is quite distracting. Gaming laptops have come a long way, but delivering a quiet in-game experience is one hurdle that hasn't yet been overcome.
We use a pair of PCMark 10 benchmarks to gauge battery life; Modern Office, which intermittently uses the writing, web browsing and video conferencing workloads from the main PCMark 10 benchmark; 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 purpose-built power plan, wireless radios disabled, and screen brightness set as close to 200 nits as possible using a calibration device.
There is an advantage to having a lower-resolution 1080p display. Battery life increases to a full eight hours, representing a 25 per cent improvement over the Legion 5 Pro.
