I watched a video by Chris Titus in which he encouraged everyone to install auto-cpufreq immediately since it does wonders for battery life on laptops.
He said it was superior to TLP and powertop auto-optimizations.
Has anyone actually used this for an extended period of time? Does it really work as advertised?
These are all wildly different tools you’ve mentioned. I’d read up a bit more and understand what you need for your system. If you have an AMD CPU, the amd-pstate driver in kernel 6.6+ is supposed to give better power management capabilities than any other tool. This is a rapidly changing area of concern though, so that opinion may be changing month to month as TLP makes changes to take AMD kernel upstream changes in to consideration.
My laptop has Intel Core i7-1165G7.
