iPhone ringer volume keeps turning down

I have a 2014 Toyota Tundra (owned since new) and never had the problem until my iPhone 11 (which was upgraded from a 6). I'll pay attention to when the issue occurs and see if it is isolated to the vehicle connection.

Likewise I never had issues with my BT/volume adjustment with my iPhone 6, until I've upgraded to iPhone 11! In my case I watched the volume dial go down on the iPhone 11 lock screen while in active playing mode switching from AirPods to the BT speaker.

It appears the problem has been happening for more than 5 months. I normally do not install Apple's beta IOS software but decided to give it a try in hopes it would correct the problem. 2 weeks ago I installed iOS beta 13.3 and that did not correct it. Thursday evening I installed the latest beta version 13.4 and that also did not correct the problem. So it appears that Apple is doing nothing to try and fix this major problem. I have missed some important calls because I have forgotten to turn up the ringer volume when exiting my vehicle. Apple products and their software have always been rock solid, but lately they are pushing their flawed products out to the public just to make more money, not make their customers happy. Having been a loyal Apple user since 2001, it looks like it is time to try another brand.

I found this thread months ago and made my comments. I even registered the issue with Apple. Still nothing. I've missed untold phone calls because of this. It's very irritating.

I'm certain this problem isn't associated strictly to GM vehicles. I was listening to my Bose bluetooth speaker yesterday and the sound completely stopped. I thought my phone battery had died. I checked the phone and found that the volume had suddenly dropped on its own to zero.

Apple! What the heck?! Please do something!

Yes my beatspro wireless headphones are doing the same thing. When people call into me the volume is extremely low. I work around loud machines and this is an issue missing calls. I was on the phone with Apple for 2 hours and they can not figure it out. I have replaced headphones, tried them on different devices and does the same thing not matter what. Matter a fact I am sitting In the store trying exchange them

My husband and I have both been dealing with the exact same issue since the update. He has an X and I have an 8. So it’s obviously due to the update and not our phones. And we both drive different model cars so it’s not that either. I can’t believe they have let this go on for so long. It’s a big issue when you can’t hear incoming calls because your volume goes down on its own. Very disappointed in Apple!!!!

I spent hours talking to Apple tech support and they don't have a clue on what the problem is. They told me it should be fixed with the next IOS update. I decided to try the beta version of IOS and I'm now on the 2nd release and it still has not been fixed.

I am having this same exact issue (iPhone 11 Max Pro) except that my Changes With Buttons has been switched off ever since I got the phone. It’s to the point now every night I have to change the volume in settings just to be sure I don’t sleep through my now silent alarms. Somedays it’s fine and will stay on max volume, other times I go into the settings before bed and it’s anywhere from 0%-30% raised. This doesn’t make any sense to me on what I am doing wrong?

Good news! I downloaded the latest beta IOS, 13.4, yesterday afternoon and the ringer volume problem has gone away. I drove my vehicle twice and the ringer volume remained at the level I set it at. So you can either download the latest beta version to fix the problem immediately or wait for Apple to release the next official update with the correction.

I was so happy to see your “solve”! However, I looked and found that sound/haptics button setting was already off. So I tried turning it on as well. Neither worked. Ringer volume still going way down again seconds after turning it up. 😩

This just started happening to my phone about 2 weeks ago. Using process of elimination I'm convinced my ringer volume goes low/off every time my iPhone connects to the bluetooth of my new Chevy truck... which I bought 2 weeks ago. Every time I leave my truck now I have to go into settings/sounds & haptics and return my ringer to normal volume. Toggling "change with buttons" to "off" does not fix the problem.

Apple did fix the problem with their latest Beta release, 13.4. Hopefully they will release the public version with this fix soon. If you don't want to wait for the released version you can sign up and download the Beta version now.

I turned that button off in sounds and haptics. It still didn’t help me. What’s annoying for me is I turn the volume back up with the side button, make sure it’s off silent mode and within less than 5 minutes, it’s back to being nearly inaudible.

I installed 13.4 a few days ago, and it did NOT solve the problem. As soon as it connects to BT in my 2020 Chevy Silverado, the ringer volume turns down to almost zero, and stays there after I exit the truck. So I still have to remember to turn it back up with the buttons. Which is really frustrating because I have a medical alert app on my phone with audible warnings. You'd think the biggest companies in the world could figure this out.

From what I’ve been told is that General Motors has this in the operating system. We need to start talking to them. The only workaround is to use your data transfer cable. If you use it you won’t have the same problem.
