Maybe. But the way I remember it is that it was clear from their side that replacing the battery would not resolve my performance issues even though I wanted to replace it to fix the random shutdowns and quickly worsening battery life. In any case, it looks like an even greater flaw in Apple's design process if they are unable to properly service a phone with a dent in the screen. It should not be unheard of, especially since they seem to keep on highlighting better and more resistant glass every year or so.
