Battery drains unreasonably fast on M1 Macbook Air

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.

even the release of the Monterey is draining my MacBook air's battery life. previously I used to get around 10-12 hours of avg usage but now it only gives 8-9 hours of avg usage.
