iphone X bad charging port

The lightning port may be clogged.

1. Turn your iPhone off. While cleaning, keep away from the power button so that you don’t turn it on again by accident. Safety first!
2. Check inside the charging port for signs of gunk using the flashlight. You will probably see buildup on the contacts at the very end, but also in the grooves that run along each side of the port.
3. Take an toothpick or other thin object (But do not use metal). Insert it into the charging port and scrape as much grime out as you can. It’s best to scrape the port, wipe down the toothpick. Be careful not to apply too much pressure, even if you’re using a toothpick. You don’t want the toothpick to break and cause a bigger problem. You also don’t want to damage the contacts by applying too much pressure.
