    How does the email function "as items arrive" work? Is it constantly checking for email?

    No, it tells your email carrier to ping your phone whenever there is new email. You can wiki "push email" if you want the non-layman's technical mumble, though.

    I don't get a lot a emails and I find that this setting actually saves battery because it is not regularly checking for emails.

    Actually, it establishes a 'polling service', so -your device- constantly pings the server. This only works for IMAP/Exchange servers. If you have 'as items arrive' for a pop/smtp service, then you are going to constantly be connecting to see if any emails are available.

    You only get 'push' if you're using IMAP. It IS constantly checking for emails.

    Incorrect. There is no constant 'ping' of the server. That's the point, to have the server notify you of new messages without the client having to initiate anything. Obviously, this requires you remain connected to the server, which is problematic with cell phones.
