Battery dies within hours while on, off or in sleep(suspend) modes. Linux Mint.

Doesn’t seem to matter if I turn off my laptop, put it in sleep mode or hibernation mode (if hibernate even works is beyond me..) my battery dies in a couple hours if unplugged. I’ve been running Linux Mint for a few weeks now and can’t seem to figure out the issue. Never had the issue on windows. I could leave it unplugged for days and still have battery left. Now it’s like a constant parasitic draw but super heavy. I’m not sure where to look or how to fix it. Also see that suspend mode seems to leave some rgbs going on the keyboard. Switching to Linux seems to have removed all rgb controls except the brightness ASUS TUF F15 Intel i5 Any ideas welcome!
