I've installed TLP on my Lenovo ThinkBook laptop and was wondering if there are additional steps I can take to extend the battery life when using the laptop unplugged.
Could you please share more tips and tricks for maximizing battery life on Linux laptops?

Otherwise you should see if power management is enabled for all your pcie and input devices (using powertop for example). If you run a nvme ssd, make sure it is allowed to use all power states (bit more involved topic).
Good luck :D
