The strangest thing just happened to my phone. I use my iPhone a lot ... A LOT. So I purchased a car charger so that everytime I'm in the car (which is very often) I can put it on the charger so it can have some juice. If I'm not mistaken, there's no way to "over charge" the battery, so I assume that this is okay. Anyhow, I went out tonight. I charged my phone in the car whenever possible. When I got home, my battery was basically at 100% ... the icon was completely full. I look at my phone a few minutes later, and the "low battery warning" prompt came up. So I rebooted my phone to see what was up. The battery was at 100% again ... then a few minutes later, the "low battery prompt" came up. Now it's sitting on the charger completely in the red, as if I haven't charged it all day. What's going on?
