Hello, lillumultipass99. I own a 2QE version which has a 4K display but I use it at 1080p resolution which I have owned for 9 months now. So far I've reached 3 hours at most while on Battery saver (Windows 10) with the brightness down to 25%, the keyboard lights OFF and only running the minimum background software. If you want to watch videos or listen to music, plugging in headphones/earphones helps conserve battery life. Full charging takes approximately 2-3 hours. There are some other issues I've experienced, though. If you're in a relatively dusty environment, do clean it often. Laptop gets dusty very easily so I clean the chassis 3-4 times per day and I still haven't cleaned the insides but they must be very dusty. Also, I play graphics-demanding games at 1080p resolution so the notebook doesn't burn to ashes due to the heavy load, but that should be obvious since the FPS also becomes very low. If you can get your hands on a Cooler Master Notepal X3 laptop cooler, it could be quite handy since it would lower core temperatures with around 5 degrees Celcius and also cool your hands while playing. If you have any other questions, feel free to ask. Would be glad to share what I know.
