iPhone SE 2020 Charging Port Replacement Guide | Easy DIY Repair Tutorial

Hi everyone, welcome back to Geardo.

If your iPhone SE (2nd Gen / 2020) is not charging properly, has a loose cable connection, or people can’t hear you clearly during calls, the issue may be caused by a faulty charging port flex cable.

Many users don’t realize that the main microphone is built into the charging port assembly, which means problems like low voice, muffled audio, or microphone not working can often be fixed by replacing the charging port.

In this step-by-step guide, we’ll show you how to replace the charging port connector flex on the iPhone SE 2, helping you fix both charging issues and microphone problems at the same time.

This repair is more advanced than basic fixes, but if you follow carefully, even beginners can complete it successfully.
