If your cable is loose your USB port is most likely filled with fluffs which prevent the cable from completely plugging into the port. The port might seem to be clean at first sight but it isn't. I've experienced this problem since the HTC One M9. It happens quite easily if you carry your phone in one of the pockets of your trousers.
You simply need to remove the fluffs and your cable won't be loose, anymore. Usually, I have to clean my phone every month or at least every second month.
