Troubleshoot the charger
The easiest way to know if the charger is the problem is to use a different one. If you can borrow from a friend who has the same device as yours, that would be better. I discourage you to buy a new charger at this point because there’s no guarantee it’s the problem.
If you have a non-Samsung charger that gives out 1.5A to 2A current, try using it just to find out if the phone would respond to it. If it didn’t, then proceed to the next step.
Troubleshoot the USB cable
The cable is very important because it bridges the charger and the phone; without it, it’s impossible for the charger to push electric current into the phone. So, after ruling out the possibility of a charger issue, you should rule out this possibility next.
One way to know if the USB cable is working or not is to use a different one and plug it into the charger (and the other end into the utility port of the phone) and see if the device would respond. You may also plug it in to a computer.
The very purpose of this procedure is to make the phone respond once plugged in but if it didn’t no matter what you do, then it’s time to proceed to the next step.
See if the USB or utility port is loose
Loose connection creates trouble most of the time. The same is true if the cable doesn’t snap right in to the USB port on your phone. If it’s some kind of loose, wiggling it to make contact may allow the phone to charge. However, if the problem is internal (like when the USB port itself is not properly connected to the board), then there’s not much you can do about it. You couldn’t even open the phone to inspect it because removing a screw by yourself will automatically void the warranty.
