Apple iPhone 11 uses the Lightning interface to charge, while Apple iPhone X uses the same Lightning interface to charge. Therefore, under normal circumstances, the charging cable used by Apple's iPhone X can also be used to charge the iPhone 11. If you are experiencing charging problems while using a normal charging cable, try the following:
1. Check whether the charging cable is properly connected and securely connected.
2. Check whether the charger is working properly, you can try to replace a different charger.
3. Check whether there is dust or foreign matter in the charging port. Do not clean it with sharp objects. If the above methods do not work, you are advised to contact Apple customer service or go to an Apple authorized repair site for further assistance.
