Input: This cable was fine for about 2 years using the cable with my genuine Apple wall charger. After that my iPhone 6s would start discharging while connected! Then it started to quickly cycle between charge - not charge - charge - discharge. If I look closely I can see dark spots on the gold plates or tabs. (See picture.) I will stick to reliable UL certified vendors like Apple or Belkin or Griffin. Because now my iPhone won’t hold a proper charge.... Luckily it has not blown up or burned as in other reviews. The newer model seems to have been updated to avoid the weak flex point near the lightning head, but I don’t see any more coating for the connection tabs.

Connection plates wear out and cause charge cycling
