Not sure if better. But the biggest change in my case was not all the changes suggested by powertop, but probably kernel changes.went from 8-9w idle, to 5-6w. Over the course of 2 years wit a Lenovo t480s. I think that 5-6w is slightly better than windows.

I get less than 5W idle on my T480 using TLP running on Debian Bullseye. Didn't have to config anything. But still it's only 8 hours.

your battery is probably being worn out. Mine's already under 80% of the design capacity. So more or less, tlp and kernel optimization has only negated the decline of my battery :/

Can you explain this, or provide a reference?
