About Push Email
Push email is one of the best advancements in email in recent years. Push email is particularly useful for smartphone owners and enables users to have instant access to their email without wasting data or battery on their iPhone.
Traditionally the iPhone checks the server for email at a set interval. This action requires the iPhone to use both battery life and data from the iPhone's data plan. Using push email it is possible to have instant access to email without having to waste data or battery on your iPhone.
Once an email arrives on the email server (in this case Google) it is "pushed" to the iPhone. The iPhone then alerts you that there is new mail available. Since the iPhone never has to "ask" the server for email, it does not expend battery life or data in checking for new mail. Push email is a great way to have instant notifications of new email which extend your iPhone's battery life and get more out of your limited data plan.
