Quick Fixes
1. Clean the Speaker Grills
Use a soft brush to remove dust. iPhone 15's bottom speakers clog easily. Gently clean all speaker areas.
2. Disable Attention Aware
Settings → Face ID & Attention → Attention Aware Features → Off. Prevents auto-lowering of volume.
3. Turn Off Volume Limit
Settings → Sounds & Haptics → Headphone Safety → Reduce Loud Sounds → Off. May be limiting speaker output.
4. Check EQ Settings
Settings → Music → EQ → Off. Some EQ modes reduce volume significantly.
5. Remove the Case
Some cases block speaker cutouts. Test without case to confirm impact.
Advanced Solutions
1. Reset All Settings
Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings. Fixes corrupted audio preferences.
2. Update to Latest iOS
Settings → General → Software Update. Later builds fix volume balancing issues.
3. Disable Bluetooth
Settings → Bluetooth → Off. Prevents volume sync issues with earbuds.
4. Test with Voice Memos
If playback is quiet here → hardware issue. If loud → app or settings issue.
5. Clean Lightning Port
Debris can cause phone to think headphones are connected, reducing speaker volume.
