Elive uses by default laptop-mode-tools, but maybe TLP is a better option?
TLP UI is a gui interface to configure it, which is pretty needed, anybody tried it ?
I use it a lot. You can install it on Elive via flatpak flathub install TLPUI . It's really just a great glorified GUI editor for tlp.conf , but that's great, and it contains a lot of hints and comments.
Thanks for the comment @Durhammer , I will make a look
