Just wondering anyone else running macOS Monterey developer beta 2 or 3 is noticing excessive battery drain?
I've filed feedback, FB9400649, regarding this.
Tentatively believe this is due to Spotlight running away with the CPU: even while the lid is closed.
Note that this M1 MacBook Air is not brand new, and Spotlight months ago built the initial index of the drive.
Force-quitting Spotlight in Activity Monitor temporarily resets CPU usage, but after a couple of hours, it is back up to 130 to 180% of the CPU.
