Default S5 not charging despite 1800mAmph

Hello everyone,

This is the current issue I'm facing, just after flashing a ROM coincidentally.

I plug the USB 3.0 cord on the original charger, I get 1800mAmph charge (seen on the galaxy current app) and yet it will not charge and it will constantly give me the notice that it is not charging.

Any thoughts aside from broken battery? Seems as I am able to charge in some random places but not all, it's a bit of hit or miss.
