iPhone 15 Microphone Not Working - Fix Guide
QUICK ANSWER
The iPhone 15 has three microphones (bottom, top, and rear). If yours isn't working, check app microphone permissions under Settings > Privacy & Security > Microphone, gently clean the bottom mic holes of debris, and test across Phone, Voice Memos, and FaceTime to isolate the app. Restarting, updating iOS, and ruling out liquid damage fix most software-related mic failures.

The iPhone 15 has three microphones (bottom, top, and rear). If your microphone isn't working, these troubleshooting steps will help restore audio recording.
Step 1: Check Microphone Access
Step 1
Apps need permission to access the microphone:
- Go to Settings → Privacy & Security → Microphone
- Check which apps have microphone access
- Make sure the app you're using is in the list
- Toggle it ON if it's currently OFF
Step 2: Clean the Microphone Port

Dirt can block the microphone:

- Gently clean with a dry, soft-bristled brush
- Use a toothpick or SIM ejector tool to dislodge debris gently
- Never insert water or liquids
Step 3: Disable Noise Cancellation
Step 3
Noise cancellation can interfere with microphone:
- Open the phone app and go to Settings
- Look for Microphone Noise Cancellation
- Toggle it OFF temporarily to test

Step 4: Test Different Apps
Step 4
Determine if it's app-specific:
- Open the Phone app and start a call
- Ask if they can hear you
- Try Voice Memos app and record a test
- Try FaceTime audio call
- If one works but another doesn't, the app may be the issue
Step 5: Restart the iPhone

A restart can fix temporary microphone issues:
- Press Volume Up, then Volume Down
- Press and hold the side button until the power-off slider appears
- Slide to power off
- Wait 30 seconds and turn back on
- Test the microphone again
Step 6: Check for Liquid Damage
Step 6
Water can disable microphones:
- Look at the microphone holes for moisture
- If wet, dry the iPhone thoroughly
- Place in a dry location for 24+ hours
- Don't use rice — it can leave residue
Step 7: Force Restart
Step 7
A hard reset can restore microphone function:
- Press Volume Up, then quickly press Volume Down
- Press and hold the side button for 10+ seconds
- Keep holding until you see the Apple logo
- Release and let the iPhone boot
- Test the microphone
Step 8: Update iOS
Step 8
Microphone bugs are fixed in iOS updates:
- Go to Settings → General → Software Update
- Install the latest iOS version
- Restart after updating
When to Contact Apple Support
Final Step
If the microphone still doesn't work, it's likely hardware:

Frequently Asked Questions
Why can't people hear me on iPhone 15 calls?
A blocked bottom microphone, a denied app permission, or aggressive noise cancellation are the usual causes. Clean the bottom mic holes, confirm the app has microphone access in Settings, and toggle Microphone Noise Cancellation off to test.
How do I clean the iPhone 15 microphone safely?
Use a dry, soft-bristled brush on the small microphone holes near the charging port, and gently dislodge debris with a toothpick or SIM ejector tool. Never insert water or liquids into the openings.
How can I tell if it's an app problem or a hardware problem?
Test the mic in several apps: start a Phone call, record in Voice Memos, and try a FaceTime audio call. If it works in one app but not another, the issue is app-specific rather than a hardware fault.
Can water damage stop the iPhone 15 microphone from working?
Yes. Check the microphone holes for moisture, dry the phone thoroughly, and leave it in a dry place for 24 or more hours. Avoid rice, which can leave residue, and if the mic still fails it may be internal liquid damage.
How much does iPhone 15 microphone repair cost?
Out of warranty, iPhone 15 microphone repair typically runs about $150 to $200. Check your coverage at checkcoverage.apple.com first, since a damaged mic sensor or internal liquid damage usually requires professional service.
