I've been experiencing some pretty horrible battery drain with my vibrant while actually talking on the phone. I am in a decent 3G area, usually 3-5 bars. I keep 3G on since I'm usually out around campus and check things online pretty regularly (and this is a 3G phone with supposedly good battery life). Over the past month I've seen pretty consistently that there is a 1-2% battery drain per minute of talk time (just look at battery remaining in Status, then go to Battery Use and see what percent of the battery is used by Voice Calls and how many minutes you talked for). At that rate, I could completely drain my battery in an hour and a half on the phone! I have had the same experience with a second battery I purchased. I might try switching to 2G one day and see how much it helps. Anyone else have similar experiences?
