Look at these HN comments about Linux laptop battery life, for example:
- "you can get a brand new Lenovo idling under 5w without that knowledge and by simply installing tlp. With additional know how you can get it under 3w" - https://news.ycombinator.com/item?id=35327618
- "have you looked into tlp? Have you tried tuning it for battery life?" - https://news.ycombinator.com/item?id=35327071
- "It's only a few years ago that we could expect decent battery life without tweaking on Linux, probably just after the T495 series. (-: These days, tweaking with TLP &c could yield worse battery life, in my experience." - https://news.ycombinator.com/item?id=35244689
- "I have a Thinkpad T495 which is also AMD based. [...] Kernel release 5.17 greatly helped battery life. Now it is just horrible even with TLP installed." - https://news.ycombinator.com/item?id=35219692
- "Not once, regardless of tlp and other tweaks and many hours of twiddling and forum-reading and keeping stats for weeks on end, has Linux ever approached Windows' battery life on the same machine" - https://news.ycombinator.com/item?id=33858033
- "Install TLP, uninstall thermald, and make sure turbo mode is off (it's on by default in Linux - probably applies to Intel only)." - https://news.ycombinator.com/item?id=33651208
- "by using $ powertop --auto-tune and $ tlp start. Disabling touchscreen, and disabling cores directly also works extremely well when I know I need a longer battery life" - https://news.ycombinator.com/item?id=32965109
- "on Linux, I used https://github.com/FlyGoat/RyzenAdj all the time for my preferred use cases (eg, setting the temp limit below when fans turn on to get a completely silent laptop on battery, lowering max power limits if I wanted to hit a certain amount of battery life, etc). (TLP has run-on-ac and run-on-bat commands so you can easily set your defaults based on whether you're plugged in or not (udev can see power events too)." - https://news.ycombinator.com/item?id=32689327
- "Every release of Ubuntu and Fedora since has caused a lowering of battery life. Current versions of both get me about 2 1/2 hours of battery life extended to 3 hours if I install TLP." - https://news.ycombinator.com/item?id=31594346

Tell me that isn't just "accumulating more knowledge of how to partially unfuck Linux"? Stumble upon the magic three letter command you'd never guess, something which you can tune and tweak which ideally requires "additional knowledge", which may not help at all and may make things worse, but several hours of trying will let you know - and to quote one of the other side comments "Can't say anything about quality of Bluetooth stack though since I don't use it".
There's a reason that the thing most people do with Linux is put it in a container, on the end of an SSH session, at the remote end of hundreds of miles of internet link, hand the SSH keys to Ansible, and use it to serve HTTP/S requests to mobile phone users - and that reason is primarily no license fee. There's a reason people use it as a home fileserver and that reason is that installing Asterisk drives a feeling of being clever and getting "something for nothing".
Instead of fixing this like it's a benign papercut, let the full badness wash over you, and then ... leave.
