I just bought my iPhone in december. I worked great until a couple of weeks ago. The battery is at the point where it dies in 11 hours. My daily usage is literally a few short calls (under 10 minutes each). I may also use a couple of apps like the calculator or weather app. I used to use the safari and iTunes all the time but my phone won't last long if I use it now. any one have any experience with this? I am hoping since I have only had the phone a couple months that Apple will either fix it or replace it.
