From what I observe last time (posted in one of the thread here). IF your push notification is set to on, and your iPhone is unable to access to the cellular data (e.g. jailbreak phone with EDGE off, or problem with the Carrier data [Couldn't use internet on 3G] etc.) your iPhone will try to connect to the internet constantly trying to fetch data off the push notification server, thus the super fast drainage of your iPhone Battery.

Solution for those who don't use cellular data (e.g. EDGE off) and want to extent the battery life = turn off push notification, turn off 3G (since u're not using cellular data anyway)

I guess push notification is only useful for those who are on cellular data plan or iPhone plan, or PPL who are not worried about the expensive on-the-go cellular data.

When my battery was draining that fast (even while charging, it is still draining) the last time round, I found out that there is a problem with VodafoneNZ 3G data in my area, as I can't surf internet while I'm on 3G, but able to do so on GPRS. turning off my 3G solve the battery draining issue (push notification still on). Now that VodafoneNZ 3G data in my area is back to normal, I can turn back on my 3G and battery life is back to normal even with all my Push notification on (incl. Beejive)
