iPhone 15 No Sound? 11 Fixes That Work In 2026

Your iPhone 15 has gone quiet, with no ringtone, no alerts, or no sound from videos and calls.

This is almost always a setting, a switch, a Bluetooth connection, or a blocked speaker rather than a dead part.

This guide goes from the two-minute checks to Apple service, and most people find the cause in the first five steps.

Quick answer: what to check first

Why does my iPhone 15 have no sound?

Apple lists a short set of causes: Silent mode, Do Not Disturb, a case or screen protector covering the speaker, and a dirty or blocked speaker or receiver opening.

Beyond those, Bluetooth routing and temporary software glitches are common, and a failing speaker is the last possibility.

Start with the cheapest checks, because they fix the problem more often than any repair.

1. Turn off Silent mode

The iPhone 15 and 15 Plus have a Ring/Silent switch on the left side.

1. Slide the switch toward the screen so the orange indicator is hidden.
2. Open Control Center and confirm the Silent mode bell is not shown as on.

The iPhone 15 Pro and 15 Pro Max have an Action button instead of a switch, and Apple says to press it or change what it controls if it is set to Silent.

Silent mode stops ringing, alerts and sound effects, but clock alarms and audio apps such as Music can still play.

2. Check ringer volume and Change with Buttons

1. Open Settings, then tap Sounds & Haptics.
2. Drag the Ringtone and Alerts slider up and down a few times.
3. Check that a ringtone is selected under Ringtone.

The side buttons change media volume during calls or media, and otherwise they change the ringer and alerts.

If Change with Buttons is off in Sounds & Haptics, the side buttons will not change ringer and alert volume, so use the slider instead.

3. Turn off Do Not Disturb and other Focus modes

A Focus can silence calls and notifications and looks exactly like a sound failure.

1. Open Settings, then tap Focus.
2. Tap Do Not Disturb and make sure it is switched off.
3. Check any other Focus, such as Sleep or Work, that may be on a schedule.

A scheduled Focus can switch on by itself, so also look at the schedule if the problem returns at the same time each day.

Apple users on iPhone 15 forums also point to Silence Unknown Callers in the Phone settings when only some calls make no sound.

4. Check Bluetooth and other audio routing

If the iPhone is still connected to earbuds, a speaker or a car, sound goes there and not to the iPhone speaker.

1. Open Settings, then tap Bluetooth.
2. Turn Bluetooth off, or disconnect the paired device.
3. Play something again and listen to the iPhone speaker.

If the audio works with Bluetooth off, the speaker is fine and the connection was the cause.

Wired headphones can also leave audio routed away from the speaker, so unplug them and check the port for debris.

5. Remove the case and screen protector

Apple says to remove any case, film or screen protector, because they can cover the speaker opening or the receiver.

If sound returns without the case, switch to a case that has proper cutouts at the bottom edge.

6. Inspect and clean the speaker openings

Look at the bottom speaker grille and the receiver at the top of the screen for lint or dirt.

• Power off the iPhone and unplug cables first.
• Use a small, clean, dry, soft-bristled non-metallic brush.
• Wipe loosened debris away with a microfiber cloth.

7. Test the speaker with the slider and a call

1. Go to Settings, then tap Sounds & Haptics.
2. Move the Ringtone and Alerts slider back and forth and listen.
3. Place a call and turn on speakerphone.

If you hear nothing, or the speaker icon on the slider is grayed out, Apple says the speaker may need service.

If calls sound like static or crackle, the cause may be the network or your signal, so try again from another location.

8. Force restart the iPhone

A force restart clears temporary software glitches that can cut audio.

1. Press and quickly release Volume Up.
2. Press and quickly release Volume Down.
3. Press and hold the Side button until the Apple logo appears.

9. Update iOS

Open Settings, then General, then Software Update, and install an update if one is offered.

Keep the iPhone charged and on Wi-Fi while it installs.

10. Reset All Settings

Use this only after the steps above, because it changes many preferences at once.

1. Open Settings, then General.
2. Tap Transfer or Reset iPhone, then Reset.
3. Tap Reset All Settings and follow the prompts.

Apple says your photos, messages, apps and documents are not deleted.

After the reset, reconnect your Bluetooth devices, Wi-Fi and Face ID, since those are cleared.

Why is sound quiet only with headphones?

Open Settings, then Sounds & Haptics, then Headphone Safety.

If Reduce Loud Sounds is on, the slider sets a maximum decibel level for headphone audio, which can make headphones seem quiet.

11. When to get Apple service

If the slider test shows a grayed-out speaker icon, or the sound is still missing after a reset, the speaker may be damaged.

• Check your coverage on Apple’s support site before paying for a repair.
• Book service through Apple Support, or use Apple Service and Repair for iPhone.
• Back up your iPhone before handing it over.

Apple’s technician guidance for speaker faults involves opening the phone and replacing parts, which is why this is a repair and not a home fix.
