Battery draining after macOS 26 / 26.2 update (MacBook Air)

I’m using a MacBook Air (Apple Silicon) and noticed significantly increased battery drain after updating to macOS 26. The issue still persists on macOS 26.2.

Battery drains faster even with light usage (Safari, Notes) and there’s also noticeable drain during idle/sleep. Battery health shows Normal, and this has continued for several days after the update, so it doesn’t appear to be temporary indexing.

Before macOS 26, battery life was much better with the same usage.

Is anyone else seeing similar battery issues on macOS 26/26.2?

Are there any known bugs, background services, or settings causing this?
