What is a power leak?

Hey guys,
I own a razer blade 15 advanced mid-2021 edition.
Recently I noticed an issue with my laptop where the battery was draining at a rate of 37W, while the dgpu was off and the CPU was using only 4W. While I usually got 5-6 hours on battery, I was only getting less than 2 hours. I asked around on a a tech channel on discord and I was told that there was a "power leak" and that I should take it for repair. However, when I checked today morning, it all seems back to normal and windows estimates around 5-6 hours of battery use. So I don't have a problem to show once I take it back to the store. Any idea what I should do?
