SumnerI 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 full ACK. having a similar experience. When I had Ubuntu gnome on my Lenovo I had around 8 hours of idling. Now I have around 4-5 with arch + lxde. Both with powertop. Haven't looked into it yet. If you find anything please let me know :D
