As of today, when I plug my iPhone 4 in to recharge (I've tried through my computer, through my AC adapter in the wall, and in the car), the battery indicator shows that it is fully charged (it shows the plug sign as opposed to the lightning bolt) even though it says its not at 100%. The percentage has been dropping over the course of the day, and it's been on without being plugged in so it's obviously not fully charged. I noticed in my car adapter that the light stays green (indicating that it is fully charged), so it seems that my phone is signaling that it is fully charged when it's not. This just started today, so I'm not sure what will happen when it drains completely. I've read a few posts on recalibrating the battery, but I'm not sure what to do.

iPhone 4, iOS 5.0.1
