I am happy owner of iPhone from iPhone 4. I never had any issue with them. All issues were some kind of my fault. But one thing is really annoying me modern iPhones – charge cables. I do not remember what year it started, but at one moment I did realize that plastic that protect lightning cable started to crack. I did not pay attention and thought that I misused it. So, I just used tape to isolate that place. But then it cracked in different place and in another place. I went I bought another cable. And year later perfectly working cable started to crack again. Cable was still working fine, just looks ugly and all wires are stripped.
