terry completely drained I couldn't get any power

I have the same problem. I've had my iphone 5 for about a year and a half. It started getting charging issues so I replaced the battery, and that didn't work. It powered on until the battery drained and would charge. Ever since that terry completely drained I couldn't get any power. So I replaced the lightning/headphone assembly hoping that would work. Nothing. I plug it into the wall and nothing. I even plug it into iTunes on my computer and get nothing.

I have been using 3rd party cables and an Anker charge brick the last while. But even using all apple cables won't charge. Would the logic board be the next step?
