Your formerly working clone Lightning cable could stop working with the latest iOS update. Previously the beta version allowed these cables to charge with a warning message but the final release actually stops many cables from working. Apples Lightning connector system is locked with authentication chips that can verify if a cable is authorized by Apple. Many users with clone cables are now without the ability to charge their iPhones.
