Just starting this thread to see if any other owners of the GL752VSK have the same issue. There has been an open thread for more than a year on the GL502 VS for this issue.
Thanks.
Some of my exchanges on that thread...

I'm located at the ASUS U.S. office and unfortunately am not able to provide much assistance with customers located overseas other than advice or suggestions if requested.
If you haven't tried it already though, suggest contacting or working with your local ASUS support and maybe your store as well if we don't see any better suggestions from ASUS HQ reps.
Getting back to your question above though, there are at least 2 different versions of the GL502VS with different cpus.
There is the GL502VS using the 6th generation Intel 'Skylake' cpu as well as the GL502VS using 7th generation Intel "Kaby Lake' cpu which internally at ASUS is called the GL502VSK model rather than GL502VS, but externally for customers we just call them both GL502VS probably to keep things simpler since they are fairly similar.
This is important to you though because ASUS HQ currently only recognizes the battery drain issue for the GL502VS model with 6th gen. cpu and 180w power supply providing options to customers reporting this issue to their local ASUS support as in the sticky thread below.
https://rog.asus.com/forum/showthread.php?94349-Official-Reply-for-GL502VS-Battery-Discharging-IssueThe GL502VSK model that you have with Intel 7th gen. cpu is using a different motherboard (and bios) than our GL502VS model with 6th gen. cpu and the GL502VSK also comes with a 230W power supply rather than the 180W power supply included with the GL502VS model with 6th gen. cpu, but may not be recognized by HQ as having the same battery drain issue as the GL502VS 6th gen. model and probably will not have the same options from your local ASUS support although hopefully they can still help you provide some sort of resolution or continue to investigate the issue with you if you want to go this route.
Anyway, apologize for the long reply, but just want to make sure you do continue to work with your local ASUS support (and store?) instead of just waiting to get a solution through these ROG forums (which we hopefully will see, but not sure?).
I have been following this issue some, but not that closely, so your local ASUS support may also have or get some updated information that I'm not aware of.
Hope this helps some?
My response:
I have the GL752VSK model and I have the same issue. I have reported before, but obviously if those who have issues with the 502 cannot get any resolution in a year +, you will understand why I have given up on trying for myself. Occurs in some games, not all. Today I played Tom Clancy Ghost Recon Wilderness and was down to 74% charge after 3 hours. I also played COD WWII and Wolfenstein 2 with no loss in battery. High/optimized settings on all 3. Go figure.
My thought is that there are probably a lot of users with the issue on Asus models who have not noticed the issue.

Yes, not sure how much more effort you want to put into it, but the G752VSK is not officially known to have a battery drain issue on the ASUS side, so you probably would need to work with your local ASUS support to show them how to catch the issue which they could hopefully find a solution for once they do.
Expect you are using the original ASUS AC adapter, but something to check. If the notebook still sees the adapter plugged in when the draining occurs though, it doesn't sound like it would be related to the AC adapter.
I don't remember any other G752VSK customers reporting the same issue, but if you're interested, you may want to create a separate post about it so it doesn't get lost with these GL502VS cases. Since the G752VSK is a larger unit, most people may leave it plugged in most of the time or not be as concerned about the battery and using it on battery power?
Not sure if it could be a problem with just your one unit, but doesn't sound too easy to catch, so hard to say.
If you're under warranty and decided to send it back for repair though, might not be easy to get the technicians to spend 3 hours playing games to try to catch it, so if you find that it also occurs running some programs or benchmarks unattended, be sure to pass this along for repair to try.
Hi Albert and thank you for the reply. I may post a new thread out of curiosity. I always use the laptop plugged in with the original battery ADP-230EB T. I am under warranty but I have this unit running great with WIN 10 CU and have never had any issues with the latest GEForce game ready drivers (currently 388.31)...so this issue is not enough for me to start from scratch, it's an annoyance...
