Why Does My iPhone Volume Keep Going Up & Down By Itself?


The volume setting on your iPhone is important. The sound of a text, call, or email coming through alerts you to check your iPhone. If you can’t hear anything, though, it’s tough to know someone’s calling or messaging. 

The iPhone is known to change volumes seemingly on its own. It does this to reset to the lowest or highest level. It may also get adjusted accidentally by the physical buttons on the side of the phone. 

The stakes are high sometimes for missing a call or text. You must have confidence your phone volume will stay at your desired level. We’re here to help with that. Keep reading to discover tips for stabilizing the volume on your iPhone, so you never have to miss another important call. 

What Makes the Volume Go Up and Down By Itself? 

There are a few reasons why this happens. Let’s look at what they are and what you can do to fix them. 

Volume Buttons 

The volume buttons located on the side of the phone often get pushed inadvertently. It can happen when the phone is thrown in a purse or backpack. It can happen inside a pocket. It also happens when a phone case is too tight, thus pushing against the volume buttons.  

You can disable those physical buttons with the following steps: 

  1. Go into Settings. 
  1. Go into Sounds ; Haptics 
  1. Turn off the option for “Change with Buttons.” 

TrueDepth Camera 

Newer iPhones, meaning iPhone X and later, have TrueDepth cameras. These cameras detect when you’re looking at your phone. They use face detection technology called “Attention Aware Features” to determine the best volume level. If you’re looking at your phone, you don’t need a loud alert.  

Here are the steps to disable this function: 

  1. Go into Settings. 
  1. Go into Face ID ; Passcode. 
  1. Turn off the option for “Attention Aware Features.” 

iOS Updates 

Apple users know that updates can fix many of their issues. If you’re having a problem, checking for an update is one of the first things you should do. Volume issues are often fixed with iOS updates. 

Here’s how to check for a software update: 

  1. Go into Settings. 
  1. Go into General. 
  1. Go into Software Update. 
  1. Allow your phone to search for an update. If there is one, click Download. 
  1. Install the update. 

Sometimes you’ll get a message stating you don’t have enough memory available to do the update. In that case, you’ll have to assess the situation and make adjustments to free up some space before you’ll be able to update your phone’s software. 

Restart iPhone 

A simple restart of your phone may do the trick. Power it off and back on to see if it makes a difference.  

If it doesn’t, and none of the other tips here work either, try a forced restart of your phone. Below are the steps for a forced restart of an iPhone 8 and after. 

  1. Push the volume up button. Release. 
  1. Push the volume down button. Release. 
  1. Push the opposite side button. Hold it until the Apple logo appears. 

When Should I Get Help From an Expert? 

Once you’ve been through all of these tricks, you should have fixed the volume issue somewhere along the way. However, if you weren’t able to stabilize your phone’s volume, there may be a glitch. If a glitch is the problem, you’ll need to seek help to fix the issue.  

Who Can Help Me? 

Find help through Apple support. You can call a support specialist to see if they can walk you through a solution. 

You can also go into an Apple retail store location. Store employees will physically inspect the phone. Sometimes they can perform diagnostic testing on your phone, too.

How Do I Change the Volume On My iPhone?

You have a few options with regard to volume adjustments. 

  • Change the volume in the Control Center pull-down when iPhone is locked. 
  • Set a limit for the maximum decibels allowed for headphone volume in Sounds ; Haptics. Choose Headphone Safety. Select “Reduce Loud Sounds.” Set your decibel level. 
  • Silence call, text, alerts, and other notifications temporarily by choosing the moon symbol from the Control Center pull-down menu. 
  • Flip the silent switch on the side of the phone to toggle between silent mode and ringer mode.  
  • You can also ask Siri to turn your volume up or down. 

What Alerts and Notifications Can I Set? 

You have the option to set tones for several kinds of notifications and alerts. Here is a list of what you’ll find in your Sounds ; Haptics menu. 

  • Ringtone 
  • Text Tone 
  • New Voicemail 
  • New Mail
