Lol, a lot of wrong information here. 30 mins only, wth. There must be something really wrong with your battery or setup. I am currently writing this from a Legion 5 Slim laptop with 13th gen i7 CPU with 20 cores total, and I get more then four and a half hours of battery life with 85% display brightness in power saving mode.
P.S. this is why I take a lot of information from Linux "pros" like you with a grain truck of salt
I agree, they are friendly, but, oh man, EOS forums are a help vampire's paradise, an ocean of beginners with a couple of knowledgeable NPCs. Constant useless noise and back-and-forth everywhere.
EOS is "for intermediate users, and terminal first distro" paraphrasing here, but that's how they describe themselves, and they are a bit dishonest about it IMO. It's "just" Arch+Calamares+forked Artix scripts posing as apps (which are buggy as hell btw).
Arch?!? lol. Terrible advice for a newbie. You are one update away from fscking your system. Better go Fedora/Nobara way. The kernel and drivers will be updated frequently enough. Also, no, propiertary NVIDIA driver installation is not a hassle, Ubuntu/Manjaro and some other friends literally have "wizards" that let you click->click->next the driver.
I like that you capitalized the R in revolutionary. Also, no they do not advocate for PSL. Electronic intifada morons all over.
