Hello, I have an iPhone 6, my charging cord has to be pushed in good into the port on my phone and I can't move my phone or it will stop, the cord also slips out of the port very easy. Before you say it, no it's not because the cord is broken I went out and brought a new one but still does it, and no it's not a cheap cord, it's a authorised Apple cord. So my question is, what is going on here? Port worn out? Or what?
