IPhone 6s won't charge unless cord is angled?

Added (1). My iphone 6s started to charge extremely slowly yesterday and today I can't get it to charge at all unless the cord is bent at just the right angle. I have tried using a pin and similar to remove lint from the phone's lightning port and it looks clean but I still can't get any better results. Any ideas?

Your cord is simply broken, buy another chatger or glue little stick-like things to the part of the cord that needs to be angled, in the angle that it should be, so it holds it straight in that way.
