I understand your concerns with your device not charging properly and I will be more than happy to take a look into this with you. I know that you stated that you have already tried cleaning the port and a new cable but there are a few more steps we can try to resolve the issue:
Verify that the device, charger, and USB cable have no physical damage
Check the USB connections for corrosion and bent pins
Inspect the device, charger, and USB cable for dust or other foreign materials
Check for liquid damage. The indicator is found inside the SIM or SD slot, and will appear pink or red if it has been exposed to liquid
The USB cable should be secured firmly in the charging port with very little mobility. If your device detects a poor USB connection, an error will be displayed
Remember to NOT use any other device's charger or third-party chargers because they can hinder charging and cause battery issues. The Samsung factory charger is required to properly charge the tablet.
