My K800i does the same. Even though when i press volume keys on side it tells me charging 100% if i unplug it then plug back in it then starts charging again. But to be honest some of my old Nokia phones did the same.
Well If I got you right, you mean that the phone is charging even if you put it on charget with full battery???
That's a bit normal for some phones imo. In fact My W800 used to do that all the time, while it wasn't the case with my K800 or the P1 I'm using at the moment.
