Turn your device off. Cut a plastic qtio in half at a 45 degree angle. Stick the plastic pointed part in the charger port. Back and forth back and forth. Apply a tiny bit of 91% or higher iso alcohol to the tip and repeat back and forth. Blow out with compressed air. Repeat process to clean contacts on your cable. 70% that's it. 15% of the time you need a new chrager, 15% battery replacement. That's been my experience.
