I keep mine plugged in all the time, because battery sucks dry quickly too. My son's is the same. We have G752VT and G752VY. 17" gaming laptops just use a lot.

You can extend your time by using some of the W10 power management features. Frankly, I prefer performance over energy conservation so that's another reason I just keep it plugged in. I am in an area with very stable power.
