My problem may be due MultiTasking.
I have changed my Mail accounts to not Push and to update manually.
I am also closing down all tasks every day. There doesn't seem to be an easy way to completely shut Apps down when you are finished with them, now that we have MultiTasking.
I have mail push on and never shut down any apps manually. I still get the same battery life as I did before 4.2
