Answer
Reconnect a certified compatible accessory, clean and dry the port, update iOS, and test another cable or charger before seeking service.
Prepare the task and protect the current state
Record the device and accessory models, software versions, exact symptom, and whether a known-good comparison works. Avoid opening hardware, using liquid or sharp tools, or installing generic repair utilities. For this task, begin by confirming the supported prerequisite: Use the accessory's supported iPhone models and an Apple or Made for iPhone certified cable where applicable.
Check compatibility and certification
Use the accessory's supported iPhone models and an Apple or Made for iPhone certified cable where applicable.
Inspect the connector
Disconnect it, check for moisture or debris, and clean only with Apple's dry, non-metal guidance.
Reconnect and update
Restart the iPhone, install current iOS, then connect directly without an unpowered hub or damaged adapter.
Isolate cable, accessory, or port
Test another known-good accessory; repeated alerts across several certified devices can require port service.
Verify the complete result
Repeat the intended action with a harmless test and confirm this final condition: Test another known-good accessory; repeated alerts across several certified devices can require port service. Reopen the relevant settings or destination and compare the result with the recorded starting state before relying on it or deleting an original.
Use a reversible recovery path
If the expected result does not appear, undo only the latest change when possible, keep the original account, data, device configuration, or downloaded file intact, and compare the exact symptom with the linked Apple Support guidance. Record the product version, time, error, and checks already completed before contacting official support.
