I applied this fix to my build, XPS 9570, i7-8750H, 1080P, 16GB, 256gb Toshiba and chose preference 2. My processor is idling at around 800-870mhz. Performance is a bit slower, but not terribly noticeable. Battery life has increased significantly. Thanks for the fix @erenatas!

Edit: my system doesn't sleep properly, the screen just turns off and acts like it's sleeping but the battery still drains like in wake mode. However when it wakes from this-non sleep state the CPU still idles around 800mhz.

It's on the to-do list. Have you tried following the instructions for CPUFriend (https://github.com/acidanthera/CPUFriend/blob/master/Instructions.md)?

If you get this to work, a pull request is appreciated.

Maybe need CPUFriendDataProvider.kext

I know @M69W , but we must configure cpufrienddataprovider, and I dont know how. I will wait to an expert :)

Instructions are linked above. Proper sleep support will likely yield better power savings. Fixing a problem and providing a pull request is a way we all end up with a better setup.

Asking everyone else repeatedly does not improve anything. Please spend the time, submit a pull request, and be part of the solution.

You do not need the "HWPEnable" option, since HWP is already enabled. See "Testing power management" section of readme.

This change is going to be of limited value - better sleep support would yield much better power savings on battery, and this is irrelevant on AC power. Closing until someone provides a pull request.

Re-opening this issue for better visibility. Pull requests welcome.

This should do. Although, It doesn't drop to 0.8 after waking up from sleep for me.

@d3myz - Check your power usage with Intel Power Gadget. It should be around 1-3W idle. Audio layout id 30 has an issue where you'll see 8-15W idle power usage after wakeup from sleep. If you can live with the headphone output not working correctly, audio layout id 11 doesn't have this issue. I haven't resolved/documented this problem yet.

Ahh, i see it. I'm clocked down to 800mhz, but the PKG anbd Core together are using between 5-15w. I don't need a headphone out. how do i switch the layout?

@erenatas I've applied the following procedure https://github.com/stevezhengshiqi/one-key-cpufriend
but cpu idle doesn't drop to 800ghz. is there anything i need to change on config.plist. I ve used the https://github.com/LuletterSoul/Dell-XPS-15-9570-macOS-Mojave config and i am only getting 1100ghz cpu idle. please help
