Excessive idle battery consumption in Whisper Mode

potatosubwoofer
Rising Star II
System: Windows 10
Battery or AC: Battery
Model: UX482EG
Frequency of occurrence: Occasionally on boot
========================
Detailed description:
After days of chasing this issue, I have found that changing from Whisper mode to Performance mode allows the system to use less battery. This appears to be a bug, as you would assume that whisper mode would have lower power consumption.
I am measuring 15-20W battery usage while on Whisper mode and the device is idle, but when I switch to Performance mode (Fn + F) the power consumption comes down to 4-6W when idle and 7-8W during light usage. This is a difference in battery life from <4hrs of idle to ~12hrs of light usage.
Is anyone at ASUS aware of this/working on it? Can anyone else confirm my findings?

Hi there,
How did you turn on "Whisper Mode"? in "GeForce Experience"?
How did you monitor the battery usage? by which software?
Thank you.

I used the inbuilt Fn+F shortcut as I mentioned. This I believe is tied into MyAsus. I used BatteryMon for checking power consumption as well as the built in Intel Graphics Command program
