iPhone volume decreasing on its own

I’ve done two things that seems to have worked:

1. Restart your iPhone: turn your iPhone off and wait for at least 30 seconds, then restart your phone. I do this before charging my phone.
2. Reinstall iOS: I downloaded the ipsw file of the iOS version on my phone and reinstalled it. A re-install, as opposed to a restore, will keep all your data on your iPhone.

I’ve only reinstalled iOS only once but continue to restart my iPhone before charging. I’ve been doing this for about a week and haven’t seen the issue in question since.

Hello Bkush04,

Have you had a chance to power cycle the iPhone? Here are the steps: press and hold the side button until "Power Off" appears. Drag the slider, then wait 30 seconds for your device to turn off. While simple, this can refresh the iOS, apps and connections. More information is available here:  Restart your iPhone - Apple Support

Do you hear a sound when you receive a message, email or other items? We want to see if some notifications are working as they should.

Are you able to determine if any app had activity that caused the reaction as if a notification was received?

Isolating the issue to the correct app will help find a solution.

Have a good day.

I have a iPhone 12 Pro Max and have an exactly same issue but only in games. The volume decrease in some seconds and then it increase back to normal level.

this happens in all games on my iPhone. It started in iOS 15.4.

Why can’t Apple fix it??

Things that didn’t work:

-hard reset

-Disabling attention awareness features under Face ID & Passcode

-Disable “Change with buttons”

-Disabling Headphone Accomodations

-Being on 15.16.1 updated version at time of this posting.

This bug is extremely annoying.  Steve Jobs would be very disappointed to have such a quality flaw on his most iconic product.  This is what I have found so far in my iPhone12 Pro:

- It always happens when using mobile data. Never when connected via WiFi.

- It always happens on the same places, even with all location services turned off.  I think it may be related to base station hand-off.  Not all hand-offs between base stations, but always on the same hand-offs from specific base stations.

- I have 2 lines in my iPhone with different carriers (one with regular SIM and the other one with e-SIM).  The problem always happens when data is routed through the line with regular SIM.

- It happens even connected through different VPNs (and also without them), so it’s not a network thing.

- It is not related with CarPlay, headphones or Apple Watch.  It happens the same with and without them.

- All apps capable of audio playing are equally affected by this bug: Apple Music, Tidal, Spotify, TuneIn Radio, Simple Radio… just to name a few.

- Tried absolutely all the fixes and suggestions on this thread, including complete reset to factory settings.  No success.  Firmware is up to date (iOS 15.6.1)

In a nutshell and despite all efforts to achieve the highest sound quality for pure music enjoyment (like Dolby Atmos and Lossless codecs), this bug completely destroys the music listening experience, which by the way was one of the most important principles related to iPhone creation. Hopefully this bug is addressed in iOS16.  Otherwise, it may be a good reason to switch to Android (or get a secondhand Walkman...)

This was a good tip.

Issue followed me to iOS 16.

I removed a few apps I wasn't using anymore, but still had a lot of infrequent use apps I wanted to keep.

So I went through Settings, and for almost all the apps (besides my ~10 most frequently used ones), disabled "Background App Refresh" and "Cellular Data" for any of them that had those settings available.

Since doing that I haven't had an audio brownout in 2 days (and several hours of listening). Hoping that's got it, and if I re-enable those settings as/when I need to for low use apps, eventually might work out which one is causing it.

Hopefully someone else can give that a try and see if it solves the problem for them.

I think I fixed this issue:

Accessibility> Audio/Visual > Background Sounds > Adjust rain volume to 50% and use when media is playing to 50%

Seems to affect this issue even when background sounds toggle is set to off.

Matching the levels instantly solved this for me

I doubt that someone who has participated in this thread are having a problem with a temporary music volume decrease when a message arrives.

The issue I am experiencing is that when I am listing music via speakers the volume suddenly decreases (e. g. when tapping on the display or pressing accidentally a side button) and then the music volume stays low unless I kill the music application (itunes, spotify, amazon music …) and start the music again.

Only killing the music app helps.

Volume bar is at maximum. Using the volume down button decreases the music volume till it’s faded away. Using the volume up button brings the music back with the reduced maximum loudness.

Locking/Unlocking has no effect.

I thought that it’s happen more often when the battery is low but I think now that is not the case. Also energy saving mode has no impact. What I could not rule out so far is the hearing protection functions.

Thank you for the reply Bkush04!

This may seem like a simple step, but have you made sure your iOS is up-to-date? Updating your iOS can potentially resolve unexpected issues:

Update your iPhone, iPad, or iPod touch

If the issue persists, reach out to Apple directly to investigate:

Cheers!

Me too! I also having this problem right now. But, in my case, I using iPad Pro 2021.

So, as you know, iPad Pro 2021 released with USB-C port. I brought several option for solving this problem.

First, I bought an Apple 3.5mm Jack to USB-C adapter, and after several hours by pluging it in. The volume on my iPad decreasing on it's own. And I change the hearing device (my JBL T110 In-ear earphone) to over-ear headphone immediately. Unfortunately, my iPad need some times to insttal the headphone driver. But it had a very bad bad bad sound quality.

Second, I bought a USB-C in-ear eaprhone. It's solve the problem, but the sound quality is very bad and it has low volume output.

The third one, I bought an adapter, it was Ugreen USB-C female to Lightning male (Model : 70953). It has a great sound quality, and also solve the problem. Now, I am using original Apple wired earpods with this adapter. A little big and heavy for mobility, but it works perfectly fine without decreasing sound volume again.

So, in my opinion, maybe it is the connection problems, to any device that connect to your iPhone, which is wired or wireless. You can try to disconnect them (or uninstall them if necessary) and then try to connect it again.

Also you need to turn off this function (if you use iPhone with FaceID), see photo below.

Edit : I hope this will help you.

I don’t know if you’ve resolved this issue yet but I have been having this problem and I think I found how to fix it I went to my settings and searched attention aware, then go to voice control and turn anything on under command feedback here’s an image

Bkush04,

Thank you for those details.

At this point it may be best to reach out to Apple directly.

You can contact them b going to Get Support.

They will take a closer look and check on available options.

Good Luck!
