Why are my iPhone 7 charge & transfer contact & cable less and less reliable (synonyms: loose / defective contact, slack joint)? Of course, the question stands for any iPhone version with the same contact type.
Context. I seem to lose more and more reliability of the cable contact or the cable during charging or file transfers. Often the connection stops almost immediately, I have to adjust the cable with some pressure. I know now that it is not about the cables, since I have bought a new one that led to the same result. Today it started to lose contact after a while, without any clear reason.
