The GS66's hardware brings all the latest computer games smoothly onto the 15.6-inch matte display (240 Hz, FHD, IPS). The equipment is also right: NVMe SSD, 16 GB of memory (dual-channel mode), and Thunderbolt 3 port.

Were you able to test at 60Hz?
;D wicked tag line >:D
Wow an Intel powered laptop with 240hz screen doesn't get the best battery life, who would've thought?
If you would've done any research at all you'd realize that battery life on a laptop with a 240hz screen is actually pretty damn good, most get around 5 hours with even the highest battery life only being about 7 hours.
Comparing the battery life of this laptop to one with a 60hz panel and lower powered chips is completely useless as a comparison, which is probably why you didn't mention anything you compared it to.
