This article provides solutions for low call volume on iPhones. Although it could be a hardware issue, there are also simple fixes for software-related problems to consider.

How Do You Fix Low Call Volume on iPhone?

Boosting your iPhone’s call volume can be as easy as adjusting the volume settings or as complex as replacing hardware. Follow these steps in order from simplest to most challenging.

1. Turn up the call volume on your phone. It might seem obvious, but sometimes the issue is just setting the in-call volume too low. You need to adjust this during a call.

   Next time someone calls you, use the Volume Up button to reach a comfortable volume level.

2. Confirm that your phone case or screen protector isn’t blocking your speakers. If they are, it could make the audio sound muffled or garbled during phone calls.

3. Clean your iPhone speakers. Speakers full of lint and dust is a common reason for muffled call volume.

4. Flip the silence switch on the side of your phone. This switch quickly silences your phone, but toggling it on and off a few times can sometimes fix low call volume issues.

   The orange indicator means notifications are silenced, while silver means all sounds are enabled.

5. Toggle Airplane Mode on and off. Switching this mode on and off a few times can sometimes resolve low call volume. Make sure Airplane Mode ends in the Off position to avoid blocking incoming calls.

6. Restart your iPhone. Sometimes, a simple restart can solve issues. Even if everything seems fine, features may not function correctly. Take a few seconds to restart your phone and then try calling again.

7. Use Control Center to see if the audio is being transmitted through the phone or a Bluetooth device. If there’s a triangle with concentric circles over the top of it, it means the audio is coming through the iPhone.

   If that indicator is not there, there could be a Bluetooth speaker, headphones, or other device connected to your phone. Disconnect that device to restore audio to your iPhone.

8. Update your iPhone.  An outdated operating system could be why you’re having trouble hearing callers. Ensure your device is fully updated and try your calls again.

   Sometimes, however, an Apple update may cause low volume issues. While you could downgrade iOS to a previous version, it might be better to wait for a fix from Apple.

   f you use Bluetooth headphones and experience low call volume, ensure they’re updated too. Driver issues might affect call volume, and updating can resolve this.

9. Disable Noise Cancellation. This accessibility feature on iPhones can help some users hear more clearly. However, some users find that turning it off significantly improves call volume.

   To disable Noise Cancellation, go to Settings > Accessibility > Audio/Visual and set Noise Cancellation to  Off (green indicates On).

   This feature is available only on iPhone 12 and earlier models.

When All Else Fails, Call In the Professionals

If you worked through all these troubleshooting steps, or the phone has physical damage (such as water damage or drop damage), you may need to call in professionals. Check your warranty status, then make a Genius Bar appointment, or visit your local Apple-authorized repair shop, to see if they can fix the problem for you.

Causes of Why the iPhone Volume Is Low

There are several reasons your iPhone’s in-call volume might be suddenly low. You could have accidentally adjusted the volume rocker during another call, or there could be an obstruction blocking the sound. Additionally, it could be due to a software or hardware issue.

Even something as simple as an operating system update could be the cause of low volume, so the best thing to do is work through the troubleshooting steps below until you find the solution.
