The battery thing is heavily dependent on what you do, though. Like using the phone as flashlight... works, but bring your battery down... almost like a always lit screen... or apps in the background that keep communicating. Your app though needs the puck to advertise only, and the phone knows what to do with it. And with that the battery life should make it.
