How to fix no sound during calls on iPhone 15 Plus

Experiencing no sound during calls on your iPhone 15 Plus can be a frustrating issue. Whether you're missing important business calls or unable to catch up with friends and family, this problem can disrupt your daily routine. Fortunately, there are several solutions to this issue that you can try at home. In this guide, we will walk you through a series of steps to help you regain your iPhone's sound functionality.

Understanding the Problem

Before we delve into the solutions, it's important to understand the possible causes of the no sound issue. This can help you identify the most appropriate solution for your specific situation.

The problem could be due to software glitches, hardware issues, or settings that have been accidentally altered. For instance, your iPhone might be stuck in headphone mode, the speaker could be blocked or damaged, or the volume might be set to the lowest level.

It's also possible that the issue is caused by a faulty app or an outdated iOS version. In some cases, the problem could be as simple as your iPhone being on silent mode or Do Not Disturb mode.

Basic Troubleshooting

Check Your iPhone's Settings

The first step in troubleshooting the no sound issue is to check your iPhone's settings. Ensure that your iPhone is not in silent mode. You can do this by checking the switch on the side of your iPhone. If it's showing a red color, your iPhone is in silent mode. Flip the switch to turn off silent mode.

Next, check if your iPhone is in Do Not Disturb mode. You can do this by going to Settings > Do Not Disturb. If Do Not Disturb is enabled, disable it.

Also, ensure that your iPhone's volume is not set to the lowest level. You can adjust the volume using the buttons on the side of your iPhone or through the Control Center.

Restart Your iPhone

If your iPhone's settings are correct but you're still experiencing no sound during calls, try restarting your iPhone. This can often fix minor software glitches that could be causing the problem.

To restart your iPhone 15 Plus, press and hold the side button and either volume button until the power off slider appears. Drag the slider to turn off your iPhone. After your iPhone turns off, press and hold the side button again until you see the Apple logo.

Advanced Troubleshooting

Update Your iOS Version

If the basic troubleshooting steps didn't solve the problem, you might need to update your iOS version. Apple often releases software updates to fix bugs and improve performance. Updating your iOS version could potentially solve the no sound issue.

To update your iOS version, go to Settings > General > Software Update. If an update is available, tap Download and Install.

Reset All Settings

If updating your iOS version didn't solve the problem, you can try resetting all settings on your iPhone. This will reset all system settings to their default values, potentially fixing the no sound issue. However, this will not delete any of your data or apps.

To reset all settings, go to Settings > General > Reset > Reset All Settings. Enter your passcode if prompted, then tap Reset All Settings to confirm.

Seeking Professional Help

If none of the above solutions work, it's possible that your iPhone's speaker is damaged. In this case, you should seek professional help. Contact Apple Support or visit an Apple Store or an authorized service provider.

Remember, it's important to back up your iPhone before sending it for repair. This will ensure that you don't lose any of your data.


Experiencing no sound during calls on your iPhone 15 Plus can be a frustrating issue. However, with the right troubleshooting steps, you can often fix this problem yourself. From checking your iPhone's settings to updating your iOS version, there are several solutions you can try at home.

If all else fails, don't hesitate to seek professional help. Sometimes, hardware issues require expert attention. Regardless of the cause, remember that most issues can be resolved with a little patience and the right approach.
