A Simple Way to Fix a Slowly Charging iPhone
Rather, as CNET’s Dan Graziano explains, it may be a simple buildup of dust or debris in the device’s lightning port. This clogged-up port may be the reason behind many people’s charging woes.
Graziano recommends using a toothpick or bobby pin to gently clean the lint or debris out of the clogged lightning port. If that doesn’t work, try using a can of compressed air to remove the build-up.
Restart and reconnect your phone, and it should charge more quickly. If you’re still encountering problems, it may be a more complicated software error, or you may need to buy a new charger.
Take charge, Apple users!
