This is a very common porblem of the iPhone 6. If the replacment of the charging port flex cable doesn´t solve the problem you need to replace the Cirrus Logic 338S1201 Audio Codec IC. In many cases this solved the problem if the error appeared after the iPhone hit the ground.

While you're right about this. It doesn't really explain why a replacement part would work temporarily. Also, if board level repair is the best option. Maybe we can refer these guys to someone. I heard iPad Rehab is good, and they have a mail in service
@theimedic it does explain why the replacement part works temporarily. If the iPhone hit the ground or something else (like this) the balls of the chip suffer under this hit. These balls can be completely disconnected or even get faulty. Try this. Use the phone until the error appears and then cool it down. If it works again the problem is caused by defective soldering balls. A simple reflow can fix this or a replacement of the IC.
Wouldn't a cold solder joint make that part never work? Not temporarily? Reflowing the bga is temporary fix, at best
I'll reball it and let you know about results
