I have a fairly new laptop and I transferred an ssd that has a Solus installation to this laptop and updated to the latest. The system works fine, but I have noticed that the battery drain seems to be very high, and indeed much higher than if I run other distros on the same laptop.
This is a screenshot for the battery drain in Solus
As one can see, the battery drain is around 25W. As a comparison, I installed ubuntu 21.04 and Fedora 34 on the same laptop and checked the battery drain as well.
Ubuntu
Fedora
Ubuntu has kernel 5.11 and consumes about 8W while Fedora has kernel 5.12 and consumes about 12 W.
I started using this laptop a month ago and at that time Solus was on 5.11. I noticed that the battery drain was much higher than on other distros with kernel 5.11 (above 30W on Solus back then). At one of the 5.12 kernels on Solus, I think the battery drain was down to below 10W. However, I don't remember at this point which release that was. Later we updated to a newer patch of 5.12 series and the battery drain increased to about 25 W. Now we are on 5.13 series, and the situation does not seem to get better.

This issue makes my battery life abysmal and I am not sure how to debug it. Any help is appreciated. Let me know if you need any more information from my side.
