If you're under warranty (and purchased from Apple) I definitely recommend that you take it into the Genius Bar. Chances are, this is likely a defective device. It shouldn't be doing this.

I have experienced the same exact thing. When I turn off push notification the battery lasts a day. With Push on it drains in hours! About 50% of the time the phone would actually heats up going into what I call "accelerated battery drain mode" so I'd turn off Push & restart the phone to try to save the battery. Nice to have it work like a Blackberry but the cost is too great. For now, I will continue to carry both device! Apple wake up.

thats weird that they replaced your phone, my phone has a 3 year warranty and when mine went dead they told me i must have 'dropped it' even though I have a case on it. So therefore they said it wasn't 'under warranty' all they do is take my money.

Hi, I have the new iPhone 3gs and I've noticed my battery life being drained more often than me friends iPhone 3g and I think mine and ur situation is similar... Once I Ty to charge my batter I connect it and the "plugged in" symbol would appear instead of the lightning bolt and it would keep gettin drained instead of recharging to gain power... So I don't know if it's my email because I have that active day and night and also a push notification for yahoo messenger???? Not sure I need help too

I have recently noticed a similar sort of problem. When my iPhone is completely dead, if I plug it into the wall charger, the red battery symbol and the charging symbol come on the screen and stay on permanently; and the phone won't charge! I am thinking that the screen uses more power than the wall charger produces.
Oddly enough, if I plug the phone into a computer it will charge just fine. Also, if the phone is not completely dead, the wall charger works as well, I presume because the screen does not stay on the whole time. I think they have a bug in the 3.0 OS related to what is run while the phone is in the "beginning charging from a dead state"-mode.

in all cases it's official apple gear (USB and AC adapter) -- either plugged into my iMac or directly into an outlet.

What are you using to do the charging? An official Apple cable or something else?

I've seen the "Push Notification stops charging" when my iPhone's in my Bose SoundDock, but never when connected to my laptop or the official Apple charger.

push contacts is a big no-no for battery life. i manage contacts by syncing with yahoo! mail contacts, it makes life much easier, and keeps the battery life up.

the push notification issue might not impact everyone. part of the reason i'm posting this is to get a sense of whether others have noticed the charging state issue. i'm not opposed to returning to the genius bar for another swap, i'd just like to get a feel for whether anyone else has experienced this. thanks!

I've used Exchange Push Mail & Contacts on my iPhone, and it drains the battery more than push notifications.

Right now I'm using Mobile Me & push notifications for 6 apps and the battery goes well, I'm not seeing any difference from before.

i wasn't aware. regardless, even with the addition of IMAP-IDLE in OS 3.0 the battery was stable and even seemed to be improved post release. the trouble began with push notifications turned on, as it seems to interrupt the charging state of the phone whenever a push notification is received.

thanks for the info!

Exchange, at least on the iPhone, is not push. I don't know for sure, but I think it's actually "IMAP-IDLE". Push itself has little to no effect on the battery life, but IMAP-IDLE keeps the email client open in the background all the time actively monitoring the server for new messages rather than being triggered from a PUSH notice. Further, OS3 added this. OS2.x did not support IMAP-IDLE.
