I am getting terrible battery life on my MacBook Pro on Arch Linux (only about two hours). I have cpupower, powertop, and macfanctld enabled. I had to use macOS for a project recently and I realized that I was getting a lot better battery life (closer to 5 hours). Does anyone have ideas of how to troubleshoot?
@sumner Give TLP a try? If you ever solve this, let me know! I normally get a little more battery mileage with Debian variants but not sure why yet.
