I have the same laptop as you. Just install the "tlp" package (The Laptop Project). I'm using Debian but the Arch package should have the same name. You can tweak the settings (/etc/default/tlp on Debian) but out of the box that should get you arround ~4W depending on what is running on your laptop. With light usage that gives more than 10 hours of battery life, even if you don't charge the battery to the max to increase its life (see START/STOP_CHARGE_THRESH_BAT0 for Thinkpads in the tlp configuration). If you have a SSD you can be aggressive on the disk suspend timeout, as there's no spin up/down wear issue as with mechanical disks. With this the battery life is good enough that I never felt the need to optimize further. [1] https://linrunner.de/en/tlp/tlp.html https://linrunner.de/en/tlp/tlp.html
