re: Charge port on iPhone isn’t working properly

I’ve seen stuff get really packed down at the bottom. Ive had to use a small pick to scrape it loose. Even used a little bit of alcohol on a cotton swab with a pointed tip. Be careful, though and make sure your phone is off. The swab would need to just be slightly damp and give it time to evaporate after cleaning. Do this at your own risk, though because if alcohol gets up in the phone it can damage it.
