iPhone 13 won’t charge. Charging port not working

Remove any debris from the charging port on the bottom of your device. Restart your iPhone or iPod touch. Try a different USB cable or charger. Make sure that you have the latest version of iOS.

If your iPhone or iPod touch won't charge - Apple Support (IN)

If you have worked your way through the steps in the Apple Support document just above your name, the next step would be to make an appointment at the Apple Store or take the phone to an authorized Apple Service shop.
