MagSafe magnets causing weird static noise/beeping when charging.

My iPhone has had this weird static noise/beeping problem whenever I charge it, whether it be by cable or wirelessly.

I have tried official and unofficial chargers and cables.

I started getting worried yesterday thinking that there might be something wrong with the phone and today, I had a chat with two wonderful apple technicians that helped me try to identify the problem. Unfortunately, the problem didn't seem to be something with the Hardware, since the analytics that I sent them seemed okay. They made an appointment for me at my nearest Apple Service center and I will be going there tomorrow to see what is wrong with it.

Since the Magnets don't really count as hardware and thus aren't able to be sent to apple as analytics, maybe this is what caused the problem after all. I thought I was crazy but I really think this is the problem here.

Has anyone else had this too? I want to see if this is a widespread "problem" or just me being unlucky with my device.
