I have had this laptop going on a month now. I have used it at the airport unplugged for basic browsing activities and movies before and surprisingly it last about 8 hours! keep it on battery saver mode of course and unplugged gaming you can get about 2 hours but obviously thats not recomended. I do hardcore video editing and rendering and this laptop has had 0 issues in doing so I use to have a Razer Blade PRO 17 2018 Edition and can tell you this laptop is light years ahead of that one. Gaming on this laptop is absolute butter as the screen refresh rate has been a consistent 70-140 FPS on about any game I play which has mostly been Monster Hunter World and Outer worlds. I run both on ultra at about 70- 100 FPS. I hope I helped im not all tech number savy but I am a gamer and developer and can tell you this will be one of the best Laptops you can buy on the market!
Hope this helped!
