I have an Asus Zehyrus M GU502GU with i7 9750h (undervolted) and GTX 1660ti. I mostly play games on it so it remains connected to the power supply most of the times but recently while using the device unplugged I've noticed that I'm getting terrible battery life. It has a 76whr battery which used to last me around 6hrs a couple of months back or so. Hwinfo shows that my laptop is consuming 33Watts of power even when the brightness is cranked all the way down, with no applications running and wifi turned off. Nvidia Optimus is properly configured so it's not an issue of the DGPU running in the background and Hwinfo confirms this. CPU utilization shown in the task manager is normal (1-3%) so I am unable to figure out what's causing my laptop's battery to drain so quickly. Please help.
