@Warlozo: Are you using an official plug adapter along with the USB cable that came packaged with the device? If so, does the issue occur at a certain charge percentage, or is it random? Have you tried powering off the phone and connecting to your charger to see if the issue persists?
To test the hardware, please head to the Samsung Members app > Press and hold on the app icon > Diagnostics > Cable charging, and follow the on screen instructions. Does this test flag any issues?
