Coming back to this, I have several CPU spins going on all the time:
* iTerm2 10–35%, disabling transparency doesn't help. There's just 3 tmux tabs doing nothing there.
* Spotlight 20–70%, the usual suspect.
* WindowServer 10–70%.
* Mail.app ~20%.
Once again HW engineers have provided great battery life that SW engineers try to destroy as much as they can.
