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
Step 2
Dirt can block the microphone:
- Look at the bottom of the iPhone (charging port area)
- You'll see small microphone holes
- 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
- If it works, noise cancellation may need adjustment
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:
