Couldn't find an answer, but found this over at xda: Android OS killing battery - xda-developers
Mine is at 15% usage right now for Android OS.
I didn't run 4.0.1 for more than 15 minutes, I literally had the update about 10 minutes after activating it. Seems the update may be the culprit from what I skimmed over that thread. If that's the case I hope Google is working on a fix. OS 4.1 was spotted couple weeks ago I think...maybe that update will be out for us soon.thanks - will definitely check that out
