Idling consumes lots of battery on mobiles, because it requires an active TCP
session. Cell phone providers use a trick to circumvent that. They send a SMS
(with a service signature that hides it from regular SMS readers) containing a
trigger signal which causes the mobile to check for new mail.

This uses less battery. You may want to check if you application/mobile
supports this.
