Phone says 100% but its still charging...what's the deal?

Ok so I've read all the threads about charging this phone for hours on end but what's the deal with this phone charging for hours while still reading 100% charged. I love this phone but I have never read more issues with charging a device ever in my life...I don't think.

Mine did that when plugged into my car charger, but it seems fine with the wall charger.
