What IM apps have you used for the iPhone, and what seems to have the least affect on battery life/performance? I need to get an app that supports Google chat and has push notifications, basically the closest equivalent to what I experience on my Android phone with gChat. I would like it to replace text messages, and I don't mind if it costs money, but I want it to run silently in the background but always be around for receiving messages.
The options I am aware of are:
IM+
Palringo
Beejive
Trillian
But I don't believe the free versions which I can test support push, so I cannot really get a feel for how well the program works and how it will affect battery life.
