A dirty charging port can keep an iPhone from charging reliably, but the port is also easy to damage. Start with the least aggressive approach and never put liquid, metal tools, or cleaning chemicals into the connector.
Safely clean around the charging port
- Disconnect the charging cable and turn the iPhone off.
- Hold the phone with the charging port facing downward.
- Inspect the opening under good light. Do not insert a pin, paper clip, knife, or other metal object.
- Use a clean, dry, soft-bristled brush to gently loosen debris around the opening without forcing the bristles deep into the connector.
- Let loosened lint fall out rather than pushing it farther inside.
- Turn the iPhone back on and test it with a known-good cable and power adapter.
Apple’s general cleaning guidance advises keeping moisture out of openings and avoiding compressed air. If compacted debris cannot be removed with gentle external cleaning, professional service is safer than digging inside the port.
Also inspect the cable connector. A damaged or dirty cable can look like a port problem. If multiple known-good cables still fit loosely or charging repeatedly disconnects, the connector may need service.
