How can I fix charging port for charger
My phone will not charge with iPhone charger anymore
iPhone 11 Pro Max, iOS 16
You can check the port to make sure there is nothing lodged in it. Using a bright light and a magnifier if you have one, use a non-conductive tool to carefully remove and pocket lint or other debris that might have gotten wedged into the port.
If that doesn't help, contact Apple to arrange for servicing:
