Diagnose Before You Pay
Before booking a repair, run through this:
- Try a different cable. USB-C cables fail more than ports. Borrow a known-good Apple-branded cable.
- Try a different power adapter. Counterfeit adapters can fail to communicate with iPhone's charging IC.
- Look in the port with a flashlight. See gray lint? See bent pins? See green corrosion? Each has a different fix.
- Test wireless charging. If MagSafe/Qi works fine, the port is dead. If wireless ALSO fails, the issue is the battery management chip (BMC).
- Test with a USB-C SD card reader or hub. Sometimes data works but power doesn't, or vice versa.
Cleaning the Port — Step by Step
- Power off the iPhone (no current = no short risk while you work)
- Hold flashlight up to the port — see lint or debris?
- Use a plastic precision pick (NEVER metal — paperclips short the contacts)
- Insert at slight angle, work toward back, drag forward to pull lint OUT
- Don't push lint deeper
- Use anti-static brush to sweep across the opening
- Short bursts of compressed air (1 sec) from 6 inches
- Repeat 2-3 passes — port lint is layered
- Test cable connection
Liquid Detection — iPhone Won't Charge When Wet
iPhone 16 has liquid detection. If you see 'Liquid Detected in USB-C Connector' alert and won't charge:
- Unplug immediately
- Place iPhone in V-tent position (let liquid drain)
- Wait 24–48 hours for full evaporation
- Try charging again
Don't dismiss the alert and force-charge — that's how you cook the charging IC.
When It's Genuinely Broken
Hardware failure typically shows:
- Bent or recessed contact pins (visible with flashlight)
- Green corrosion (liquid damage)
- Cable falls out easily / no resistance when inserting
- Wireless charging works perfectly but wired never does (after thorough cleaning)
Apple's port replacement runs $129 out of warranty or $99 with AppleCare+ accidental damage. AppleCare+ may also classify it as a manufacturing defect (FREE).
