I'm curious as to why you recommend TLP instead of using power-profiles-daemon that is built into Gnome?
Regarding the use of TLP, it seems we should also disable power-profiles-daemon as well as enable the service (from TLP 1.5 documentation for Fedora https://linrunner.de/tlp/installation/fe...).
Fedora 35 and higher as well as Rawhide
Uninstall the conflicting power-profiles-daemon package:
dnf remove power-profiles-daemon
To complete the installation you must enable TLP’s service:
systemctl enable tlp.service
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
