I'm planning to purchase a used T480, and want to know how the battery life would be on Linux. Online I see a lot of good numbers, and I am considering carrying multiple of the external batteries, but I want another opinion. Also, do you have any recommends on a good price to "go for it" and any other laptops to consider (up to but preferably well under 600 USD, good battery/portability, linux) to consider.

have you checked if your laptop uses C states correctly?

Is the cpu governor set to powersave?

This is in windows so everything is already preconfigured.

And yes I get worse to the same battery life in linux unless I go insane with the settings and get awful performance too.

ah, my bad.

I don't know why your T14 has that bad of a battery life, but pretty sure the H series of intel CPUs have really high power usage in general
