iPhone 17 Pro Charging Port Replacement
If your iPhone 17 Pro is struggling to charge, constantly disconnecting, or failing to transfer data via USB-C, the charging port assembly likely needs replacement. This repair is also necessary if the lower microphone stops working or if you receive persistent liquid detection warnings. Expect a complex teardown that involves removing the display, the Taptic Engine, and the bottom speaker to access the glued flex cable.

Frequently asked questions
Yes. The lower microphone is integrated into the USB-C charging port flex assembly, so replacing this part will resolve bottom microphone failures.
The USB-C port does not strictly require Apple Repair Assistant calibration for basic functionality, but running the diagnostic tool is recommended to ensure all sensors and data lines are working perfectly.
Ensure that the flex cable is fully seated on the logic board and that the battery connector is secure. You should also verify that the replacement part is not defective by testing it with a known good USB-C cable and a 20W adapter.
No. Opening the iPhone destroys the original waterproof seal. You must clean the frame and apply new adhesive to maintain moisture and dust resistance.
