I am no expert, but I think this is pretty typical with electronics. If the battery is shot, the components shut down. Apple or anyone (right now) can't magically fix this. It is an inherent issue with batteries that I actually see as a major disappointment in progress over the last 10 years. In Apple's eyes, they tried to remedy the issue by keeping your phone powered on, just at less power, so that you don't miss an important or potentially life saving phone call. I think that was the right call, but they should have been transparent about it. Looking at the response of people on these forums though, they should have just let the phones die as batteries do and move on. They didn't need to do any of this.
