🔌 iPhone 13: Why is my phone not charging?

My iPhone 13 has suddenly stopped charging properly. The charging symbol shows for a few seconds, then it disconnects on its own. I have tried different cables and adapters with the same result each time. The port looks clean, no visible lint. Turning it off and back on helps briefly, but the problem returns within a day. What could be causing this?

This could be caused by a faulty charging port, damaged internal charging components, or a battery issue. Since you have already tried multiple cables and adapters, the phone itself is more likely to be the problem. Try gently cleaning the Lightning port with a non-metallic tool and check for moisture warnings. If the issue continues, have the charging port and battery inspected by an authorized technician.
