Maryanne's iPhone 6 won't recharge and now it's dead. What can she do? Rich says that her iPhone battery could be depleted or faulty. The battery in the iPhone has a limited number of charges, and once it surpasses that, the battery will die. And being an iPhone 6, it could be that the battery needs replacing. But before doing that, she should try using a gentle burst of canned air into the lightning port. If it starts to charge, then she'll know there was just a little dirt or fluff blocking the connection. If it doesn't work, then it's time for a trip to the Apple Store.
