Fixed: iOS 15 iPhone volume suddenly low on calls?

iPhone low volume issue is a common problem that thousands of consumers are facing. Your device might be suffering from software-related issues, or it could be a hardware-level issue. We are going to figure it out by applying software-based solutions and come to a conclusion to seek professional assistance.

Close iPhone Background Running Apps

Applications like Discord, FB, and other communication apps reserve the majority of the volume. Of course, the communication-based apps such as Discord do it, and your phone volume goes down drastically. You cannot connect to the voice channel, and use other apps in the background is not possible at 100% volume. Your phone will distribute 70% volume to the app, and 30% to the outside of the app.

Step 1: Double-tap Home Button on iPhone 8 or earlier, and swipe up from the bottom of the screen and hold the screen in the iPhone X or later. The iOS reveals the list of apps running in the background and swipe up on any app to close it.

Step 2: Now, find the app that is causing the problem and swipe up to close it.

In our case, it was Discord and FB, and it could be anything else. You don’t have to worry about closing all apps from the background to listen to music or videos on the phone. We recommend closing running applications one-by-one to identify the culprit and close the case.

Muffled & Cracking Speaker & 3.5mm Jack Output

It is common among consumers, who mention speakers specifically in the official forum threads. Apple engineers added one speaker in the earlier device because one grill stands for primary microphone and second grill designed for primary speaker. The Cupertino-based company adds necessary protection layers to keep the dirt mites, and dust particles from entering the grills. A consumer’s environment plays a crucial role in the process, and age is another possible factor.

Solution #1: You can put a compressed air gun into the action to force the clogged speaker grill to free itself. You can also set the hairdryer into use, but we don’ recommend it as it also releases hot air in the process.

Solution #2: Dust removing cloth or NIKON LENS PEN, which is specifically designed to remove the dust from the small areas. The fabric works flawlessly, but it might not be able to reach the small vents because of the size.

Solution #3 (worked for me): I always thought that my iPhone speaker is defective, but I tried removing the dust and dirt with air using my mouth after eight months. However, there’s a risk of releasing saliva liquid particles in the vents that can lead to many problems later down the line. But, it worked, and my iPhone speaker is usually working.

Solution #4: Cotton Bud is another solution when you don’t have an air gun or compressed air gun. Dust particles don’t leave the space quickly after being there for so long, so you need a scrubber that can move it. Cotton Buds come in handy for touching the dust particles and removing it, and it works as a scrubber. You will noticeably heat the difference and make sure to blow air from your mouth after cleaning to remove remnants of it.

The solutions that I have mentioned here worked for me, and I’m accurate that it will work for you. Ensure that your equipment is not releasing hot air or liquid in the process. The excess heat can damage the speaker, and fluid is the enemy of PCB and components.

Turn off Volume Limit (do this to all music apps)

Apple added Volume Limit to protect the consumer ears, which is a reasonable safety measure. However, you can turn it off in the Music app, but we recommend not doing it because it indeed designed to protect your ears. If you listen to the music for (2 or 3 hours) more extended hours, then I recommend the music or media consumers keep it this way.

  • Tap on the “Settings” and then “Music.”
  • Swipe down to the bottom and tap on “Volume Limit” to continue.
  • Keep the volume bar to a maximum of 100% and go back to check if the option is turned off or not.

  • We are not done yet and tap on EQ in the Music app.
  • Turn off the EQ option for now.

You don’t have to restart the device to apply the settings because it is considered an excellent habit to reboot the machine. Every Music app has a volume limit or EQ system that utilizes its algorithm. Spotify has plenty of music enhancing options, and you can turn them off to experience RAW performance and culprit at the same time.

Turn off Do Not Disturb (DND)

Thousands of iPhone and iPad consumers enable the DND feature, and they forget it. You might have helped it, and forgot to disable it because it doesn’t impact the day-to-day tasks until or unless it is related to the speaker or earphones.

  • Tap “Settings” and swipe down to open the “Do Not Disturb” setting.
  • Tap on the “Do Not Disturb” setting to turn it off.

The iOS silence the incoming calls, and notifications will be disabled. Keep the function turned off to ensure that it doesn’t happen again.

Turn off or disable Phone Noise Cancellation

Millions of experts suggest the iPhone consumers turn off the Noise Cancellation to improve the sound output from the speaker and earpiece. You can always revert the settings, so don’t worry about the drastic changes to the configuration.

You can turn it back on, and it will work usually. You won’t see drastic changes by turn off Phone Noise Cancellation, and it will impact positively for minorities only because of the environmental differences.

Apple Service Center

If your Apple device is under warranty, then you should seek professional assistance from the service center. Do not hesitate to contact the nearby Apple store and make sure to read Google reviews of the store.

Final Words

Now, you can fix the iPhone low volume issue or make iPhone louder during incoming calls by following simple solutions. Remember, you cannot recover 100% volume and quality on an old or ageing iPhone because the components get more aged. Apple did not add a secure protective layer to keep the device from dust particles, and you have to clean it manually in the store.
