My Galaxy S5 won't charge it's battery?

[Derekbbn]

Hey guys. I have a S5 that won't charge it's battery. The phone says its charging, but the battery won't charge. Even when I have the phone plugged into a charger, the battery continues to drain as it would normally. I work at a phone repair store, so I was able to test it with multiple cords and charging blocks, along with different batteries. I was also able to replace the original charge port with another we had in stock. Same result, nothing.

Anyone have any idea whats going on? In the imgur there is a picture I took in the Galaxy Charging Current app while the phone is hooked up to a USB 2.0 port on my PC. Reference and average register 450 mA and max is 460 mA

Welcome to Android Central! I wonder if there might be some charging circuitry beyond the port that is defective.

Thanks! I've lurked on here for a long time and decided now was as good of a time as ever to sign up. And that's what I'm unsure of. I can get just about any part I need to fix this thing. I just need to figure out which part is defective so I can replace it.

That's getting too technical for me. It sounds like you've already replaced what you can within reason. I would guess that if there's a problem with one of the actual charging circuits, you might have to replace the whole motherboard.

What if you try to load it with another adapter?

If you have already tried to change the battery.. well i think you should bring your phone to repair
