iPhone poor battery life with 2.0 firmware and applications!
A little more research today. Appears like the applications are chewing up the battery. When the phone is put into sleep mode it doesn’t appear the applications are closing down their IP threads. Potential related 3g connectivity problems would then force the radio to power up while in your pocket, on your desk etc. Many people on the net saying their usage time is extremely high compared to standby when they had the phone locked most of the day.
Appears applications that poll for new messages (NetNewswire, Twitterific, Facebook, etc) are key culprits.
Try a test. Leave an application which polls for new data active, and sleep the phone. You may just notice your battery runs down very, very quickly.
Thoughts?
I also removed the applications and (thank you) I did much better with battery life. However, I fear that the one app that is still on there is the biggest cause of the battery drain - Exchange!
I hope this is not the case but I fear that I will need to disable “Push” and put in on Manual or every 15minutes
will keep you posted

Wow! Well then, is it apps or MobilMe that’s doing it? It it’s apps, which ones should we get rid of?
