Test Each Mic Independently
iPhone has 3 microphones — only one might be broken. Test each:
- Bottom mic (used for calls): Make a phone call. Ask the other person if they can hear you. Or use Voice Memos and record while speaking.
- Top mic (used for FaceTime): Open FaceTime and call yourself or a friend. Or record a Voice Memo while holding the iPhone like a phone (mouth near earpiece).
- Rear mic (used during video): Open Camera → Video → record yourself talking. Play back. If audio is fine in normal Voice Memos but missing in video, the rear mic is dead.
Cleaning the Mic Openings
Mic ports are tiny holes. Lint and pocket fuzz block them.
- Locate the mic openings:
- Bottom mic: in the row of small holes near the Lightning/USB-C port
- Top mic: small holes between the speaker and front camera
- Rear mic: tiny pinhole near the rear camera lens
- Hold the iPhone with mic facing down so debris falls OUT
- Use the soft brush to sweep across each opening
- For wax buildup, dip a Q-tip lightly in 99% isopropyl alcohol and gently work around the openings
- Test after each pass
Software-Side Fixes
- Restart iPhone. Often resets stuck audio state.
- Toggle Bluetooth off. Audio may be routing to a remembered AirPods/car/speaker. With Bluetooth off, the iPhone's internal mic is forced to be primary.
- Test in different apps. If only Zoom/Messenger/etc. fail but Voice Memos works, the issue is app-specific. Reinstall that app or check its mic permission (Settings → Privacy → Microphone).
- Update iOS. Check Settings → General → Software Update.
When It's Hardware
Mic hardware fails after:
- Liquid damage (water in the mic port corrodes the diaphragm)
- Drop damage (mic flex cable can snap)
- Manufacturing defect (rare; covered by warranty)
Apple repair is $129–$169 to replace just the mic assembly. AppleCare+ accidental damage is $99. Often Apple replaces the entire bottom assembly (mic + speaker + USB-C/Lightning port), even for just a mic issue.
