I absolutely agree about OTA updates being inadequate and mucking things up. That is why I have always updated via iTunes. I back up my data, then I update, and then I do a restore as new. I have yet to have a battery problem that way.
With Android, you must do a factory reset after the update. This will avoid all kind of problems down the road.
