On: PowerTOP – diagnose issues with power consumption and power management on Linux

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?
