I had to exchange my iPhone 3G already due to hardware problems now with the exchange I have this is what the battery gives me look at the usage, and the standby then look at how much battery I have left?!?! is that normal?

If you just exchanged it, is it a new phone? Have you conditioned the battery, yet, with a full drain-until-it-shuts-off charging cycle? That looks low, but not unusual for a first charge. A few cycles should get you up to some better stats.
Have you drained and recharged the phone? Do you have 3G and Location Services on? Listening to streaming radio, YouTube, making phone calls?

Drain the battery, turn off 3G (since you are on Wi-Fi), and turn off Location Services, then see how long the battery lasts.

The thing is, even if you don't use it, the screen, 3G radio, and location services drain the battery, even on the EDGE iPhone.
I would say it is not normal, but then again, the battery indicator is not really accurate. Let it run all the way down to figure out how long it lasts.

I use an iPhone EDGE and use AOL Radio for about 4 hours each day, so I can't really tell. Before 2.0, I would get about 6 days of standby time.

Yes, 3G is on no raid no youtube all I do is text and rarely Call
hmm if you were doing some heavy surfing/radio or maybe GPS i could understand that. but if you did just text and say 1-2 phone calls.
question. was all 2 hours from just pure texting?
