Linux Laptop Power Management
The cluster discusses optimizing battery life and power consumption on Linux laptops through CPU frequency scaling, governors, tools like TLP and powertop, undervolting, and comparisons to Windows power profiles.

One can always set their processors to lower frequency temporarily.
Do you have a discrete GPU? Disable it. Run TLP and powertop to see what uses too much power and to adjust tweakables.
I need to try that cpufreq for battery life...
Windows has a power setting, that chooses between CPU throttling and fan speed increase.
That's kind of irrelevant anyways, all modern CPU's have speed stepping functionality that can reduce the clock speed while on battery.
But windows has power profiles, intel utilities to undervolt and limit boost clock
Would powertop be able to help?
Have you tried different cpu governors?
Using auto-cpufreq or other cpu frequency scaling services can make my laptop run way longer than with windows.
Try using powertop to help tweak power settings Linux may have overlooked by default. It's in the repos, last time I checked.
