I dont buy that stat regarding the standby time that the phone displays. I had the phone on yesteday and when it was at 37 percent the phone said standby of 13 hours and when I look at it right now with just down 5 percent (95 percent left) (And that is a rough estimate on percentage because I have other app monitoring software that was saying 99 percent after 4 hours.) It says 3.5 hour standby time. I don't think there's anything wrong with the battery on the phone, I think that the software isn't properly monitoring the battery life. I would recommend that some of you try something Like Battery Magic and take a look at what that has to say about the amount of time you can do different things. I have already stated this in another thread but basically it goes into how long you can watch movies, talk on 2g/3g, play games, listen to music, standby, etc. When my Iphone 4s is fully charged it says that I have 300 hours of standby. That's about 12.5 days. Don't think it will last that long, but Still if other apps are reporting different things than the OS then there's obviously something not quite right with the O.S. with regard to the reporting.
