The most common reason for charging problems is not a defective charger, but rather dirt. When your phone charges slowly or even fails to charge at all, first check the iPhone charging port and consider cleaning it instead of labelling the charger as faulty. Clean the debris easily using a soft brush or a wooden toothpick. Knowing how to clean the iPhone port correctly can save you from buying a new charger or visiting a repair shop. Your phone’s charging can make a big difference with a simple cleaning.
