Galaxy S5 Charging On And Off when not plugged in

Ive recently got a Galaxy S5 running android 5.0 when the phone is not plugged in it is constantly flashing on and off as though the charger was being plugged in and unplugged. This is killing the battery, it happens about every 30 seconds.

I have tried several factory resets and cleaning the micro usb port but still the same

If cleaning the port doesn't fix it (that's the usual cause), have it replaced. It has an internal problem (probably a short).
