I am wondering about the battery life on my iPhone since I did the 1.1.1 update and JB/activated it! I have had it on for 13 hours since it was fully charged and it was down to 10% remaining before I put it in the dock to charge. I got the train somewhere and I would not normally use it so much! Out of those 13 hours I sent about 10 or so txt messages and made and received 5 or 6 calls lasting around an hour at most in total. I also surfed the internet for approx an hour as well as listening to music on the phone for approx 5 hours. Does that sound like it is in line with Apple battery life estimates? I remmeber when I previously used my phone on the train on 1.0.2 this much I used the iPod for about 5 hours and made maybe 30 mins of calls and sent around 10 texts but didn't use more than a few minutes of wi-fi and the battery logo did NOT drop at all - it was still full as far as the icon was concerned! Obviously I used the phone much more today and maybe it would have dropped on 1.0.2 if I used it as much but I am curious on the guidlines that Apple put out!? Any thoughts?
