However, many users have frequently complained about their microphone not functioning properly and the microphone volume being inadequate, resulting in an unsatisfactory user experience.

If you find yourself in a similar state, where your life feels like it has regressed to a bygone era, you have come to the right place. Let’s delve into this article and fix this microphone issue.

Sometimes, when faced with an issue like low microphone volume, we tend to overlook the possibility of human error.

To solve this, try holding the phone in a different manner and carefully observe the placement of your hand or fingers in relation to the microphone. This will help ensure that the problem is not due to human error.

Test The Microphone To See If The Problem Lies With A Specific App

To verify if the microphone is truly at fault, it is essential to conduct a thorough examination. There are instances where certain apps appear to have microphone issues when, in reality, they are the ones causing the problem. In such cases, the microphone is unfairly blamed.

However, it is crucial to perform a check to confirm.

  1. Begin by opening the Voice Memo app on your iPhone.
  2. Record an audio sample.
  3. Then, proceed to use different apps to record audio or make calls.

By doing this, if the audio recorded on the Voice Memo app sounds clear while only a specific app exhibits poor audio quality, you can conclude that your microphone is innocent in this scenario.

As previously mentioned, recent iPhone models are equipped with multiple microphones, and it is possible that only one of them is experiencing a malfunction.

To investigate this further, you can:

  1. Open the Voice Memo app.
  2. Start by recording various audio samples while speaking closely to each specific microphone, one at a time.
  3. Afterward, listen to all the recorded audio samples and carefully identify if the issue persists with only one microphone.

This way, you can pinpoint the problematic microphone and focus on fixing that particular one, potentially resolving the audio problem.

Use Volume Buttons To Increase Microphone Volume

The volume buttons located on the side of the iPhone can also be utilized to increase the microphone volume.

At times, the volume may unknowingly be set to a low level, and if you happen to adjust the volume during a call, it is possible that only the ringtone or notification volume is increased rather than the media volume. This can lead to the mistaken belief that the microphone is the source of the problem. To address this, you can:

  1. Begin by enabling the microphone for the specific apps that require it.
  2. Afterward, you can use the volume up button or directly slide up the volume slider from the Control Center to increase the microphone volume as needed.

Clear The Path: Clean Your Microphone

Another potential solution is to clean the microphone jack. Sometimes, debris can accumulate and hinder the flow of sound between the microphone and the user, resulting in a perceived decrease in volume.

To address this, you can attempt to determine if the microphone is dirty by gently inserting a soft, small piece of cloth and moving it sideways within the jack.

Removing Obstructions From Your Microphone

Occasionally, an obstruction can impede the functionality of your microphone. Many individuals often attribute this to the phone case, assuming that it is causing a decrease in microphone volume.

In such situations, the solution is quite straightforward. Simply follow the aforementioned basic steps, including removing the phone case, to assess if the problem is resolved.

If the issue persists, only then it is advisable to proceed with basic troubleshooting fixes to address the microphone problem.

Introducing one of the simplest and most effective solutions to tackle various underlying issues with your phone and its apps: say hello to rebooting your device. To perform a reboot:

  1. Press and hold the power button until the option to slide and turn off your phone appears.
  2. Slide and turn off your phone.
  3. Wait for approximately 30 seconds to a minute.
  4. Then press and hold the power button again until the Apple logo appears, indicating that the phone is restarting.
