Alright this is going to be a little lengthy. I have had to RMA this laptop twice and the issue still has not been fixed. The issue I’m getting with the laptop is the laptops battery will discharge while plugged into the wall outlet. This occurs while I’m playing a game or rendering files in AutoCAD. The laptop battery discharges at roughly 6%-12% every 30 minutes. I have had the laptop shut down on me in about 6-7 hours when I’m using it for work and a bit sooner while on a long gaming session.
I have tried two OEM power bricks, updating ,and downgrading the BIOS. I have updated all my drivers, windows, and anything else that would be pertinent to this. I fiddled with the windows power management settings for giggles. The only thing I have not done is underclocking the CPU as I don’t want to possibly break the manufacturers warranty. After I did all this I decided to RMA the laptop and the first time they just reinstalled windows. Which obviously didn’t solve anything. I have now gotten back a second time and it is still doing it. According to their support their technicians replaced the motherboard. Still didn’t fix the issue.
It’s hopefully a battery issue since I’m in the middle of a 3rd RMA. If not then, from what I can deduce, the laptop either has a insufficient OEM power brick or the overall design for power delivery is poor. This is the first gaming laptops I’ve ever had do this. I’ve owned 4 others with this being my second Asus. I have no idea if other users are having this issue as I haven’t heard/seen anything yet from googling, though, I do know there GL502VS was having this issue as well.
tl;dr:Laptop drains the batter while plugged to a wall outlet during a CPU intensive task. Asus RMA can’t fix it.

UPDATE(8/27/18): So I got the replacement back today and I’m still seeing the same issue. Pretty much figured out it’s most likely an issue with this particular model. I believe the issue stems from an insufficient power brick(~180W). It could also be a bad design for the motherboard. I’ve fiddled with some other stuff such as the disabling hyperthreading and lowering the voltage to about -.250V which was the only way to stop it from draining the batter while plugged in. I’m going to buy another power brick with a higher wattage and see if that solves the problem.
Since someone PM’d me about this: I’m also seeing thermals around 80C for the both the GPU and CPU, which is pretty normal for how thin this laptop is.
