I set Claude loose on my computer and said “why is my battery life so bad?” and it found an always-running audio subsystem kernel extension (Parrot) which didn’t need to be there and was preventing the CPU from going into low-power states. My battery life got noticeably better when I deleted it.

I’m not even sure how it got installed, possibly when I installed Zoom for an interview once but I don’t know. Point is, at least in one case, AI can help track down battery hogs.
