iPhone doesn't respond at all.

Hey iFixit members!

I do have a big problem with iPhone 5s I was using.

So the phone doesn't charge. (which is kinda weird, because the phone looks almost new, always been in a case, and never dropped or opened) I checked the lightning port on iPhone, and it was clean. As you can see.

It works only with one cable. I have tried almost 10 different cables and still it didn't work.

I work a lot with iPhones, as I'm changing screens and batteries usually, still i haven't never experienced this kind of problem.

What can cause this problem? Thanks!
