Best way to find out if it'll help you is to try it out! It has 2 modes, "monitor" which help you evaluate what it would do for you without making any actual changes.
If you like what it suggest you can run it in "live" mode, which will make the suggested changes. But after you stop "live" mode after reboot all settings will go back to defaults.
If you're happy with results then and want to run it in background all the time proceed with "install".
I tried it out. It doesn't get temps, as I expected. But it does switch down into power save mode on battery and switch back to performance on AC. Battery life has improved by over 50% from 4h to over 6h. Thanks for making this!
