So recently I've noticed that my iPhone 3G has had pretty bad battery life. Now, I've read all the complaints on here about 3.0, and because of that, I figured that 3.0 was the main culprit... Until today, that is. After some fairly light usage, surfed the web, mainly to this sight, and used Maps and GPS a few times (LA is hell to navigate without something to tell you where to go), I watched my battery life free fall. So before my iPhone died, I took a screen shot of my usage. I took it ruffly right after the 20% warning appeared, so I guesstimate my battery life to be at 15%. Now, I'm not a battery life nazi. I don't compared usage screen shots or anything like that, BUT, my battery dying after only 2.5 hours of use seems a bit ridiculous to me. So, to those of you that are battery life nazis, would you consider this unusually bad battery life and/or worth of a trip to the Apple Store for a replace?
