My iPhone ringer volume is going up by itself

As info...

On or about January 2, 2021 my iPhone 6s+ started increasing its ringer volume on its own after I hang up from a call. I am running iOS 14.3. This is very annoying since I like to keep my ringer volume very low.

My temporary fix for this odd malfunction was to go to SETTINGS, SOUNDS, and turn off "Change With Buttons" and then set my ringer volume low with the Ringer and Alerts slider.

Now when a call comes in (I answer and then hang up) iOS tries to increase ringer volume but fails.

I’d be interested to know how many Me Toos on here have Tiles. I think this may be the problem I’m having as it does seem related to Bluetooth as many have noticed, AND the Tile app has permission to turn your phone volume all the way up when you’re doing the Find My Phone feature. Seems like it could be related.

my issue resolves when I turn my BT off. So it’s definitely related to that. Not a long term fix tho...

So I noticed something different about this issue after the latest update done on my iPhone SE.

Now, if we turn off ringer volume “Change with buttons” inside Sounds and haptics, this problem doesn’t occur anymore which was not the case before the update. Now, I can connect to Bluetooth earphones or my EarPods, leave the phone on loud, and the ringer volume doesn’t go up anymore.

Update: this fix works for me...

SETTINGS > SOUNDS > turn off "Change With Buttons"

iPhone 12 Pro here, with latest iOS 14. Been happening since I got the phone across all versions of iOS 14. Turning off adjust with buttons doesn’t solve the issue. It’s inconsistent where ringer volume (not media volume) goes to max. I am wondering if it has something to do with my Bluetooth headset. I’m going to pay closer attention to when I use the headset and if that affects ringer volume. Regardless, it would be helpful if Apple would address it.

one thing I’ve done to help is I setup a shortcut based on location, so when i get to work, automatically change ringer volume to 20%. When I get home, change it to 50%. Not a great fix, but it’s something. Shortcuts kinda bug me too because you can’t set it to automatically happen. You get an alert that you have to tap and then run. Seems like apple missed the boat on the shortcut automation features.

I discovered it happens when my phone (iPhone 8 running 14.3) is connected to Bluetooth and I text or use the keyboard. If not connected to BT, then it never happens, only when texting with BT connected. Turning off the "change with buttons" seems to alleviate it but then I can't adjust the ringer volume easily. Apple, you need to fix this.

I’ve found a workaround ... I set a reminder daily for 9:45pm to check my alarm volume and turn it back down if needed. 🤦🏻‍♀️ It is not an elegant solution, but so far it’s working. (2 out of 3 days I do need to fix the volume at bedtime!!) My phone connects by BlueTooth to my watch, car and occasionally headphones. I haven’t been able to figure out what is triggering the max volume shift. It is definitely annoying!! Apple, please fix!

I had the XS and noticed this started to happen after the newest update. I couldn’t figure out if it kept happening in correlation with something else for a while. Then I realized it seemed to happen after being connected to a Bluetooth device, such as a speaker or my car. I thought it was just a weird glitch with my phone but it was very annoying. I recently upgraded to the 12 Pro and it’s still happening. My guess is it is a software glitch with the new update. I hope they fix it soon because it’s FRUSTRATING!

I have this problem as well and while I haven't found a solution, I think I might have found a cause.

I'm using Spotify on both my mac and my iphone and they are connected with spotify connect. On my mac, the spotify volume slider is at 100% and I use the system volume to adjust the sound volume.

Now, I realised that when using spotify on my mac, I can adjust the spotify mac app volume slider with the volume rocker on my iphone, and the iphone ringer volume is set to whatever volume the spotify mac app is at. Hence the ringer volume sets itself to whatever the volume of the spotify mac app is, whenever I use the spotify mac app and it communicates with the iphone spotify app through spotify connect.

Jan2021. same issue with alert sounds arbitrarily increasing to full volume. i’m on an iPhone Xs and iOS 14.3 but it’s only started happening within the past week. i’ve done nothing that would have caused a change and i cannot seem to find any consistency in use or timing that prompts the issue.

oddly, my two teens also have a problem with the alert volume on their Xr models with 14.3 but their volume decreases to all the way down, meaning silent.

I have something to say to Apple:

Can you just solve this issue? otherwise it is pointless to have this - Change with Buttons feature build in. Obviously this is a bug, just solve it. Change with Buttons is useful coz I can adjust the volume as and when also the level of the volume. Please don't create more disapointment to you long loyal users here.

Add me to the list. My phone keeps jacking the ringer volume all the way up without me doing anything. It startles me when I get a call and I've been embarrassed by it in public more than once. I thought I was doing something wrong till I saw this thread. I'm running 14.3 on a 12pro.

I also have the Lock Screen sound issue that has been bugging other customers.

Ditto, happening here for the last couple days, very annoying, very loud.

Mine does it too on my SE. Mostly happens when I plug it into my aux/carplay and unplug it. Might be a glitch in the software, nothing we can really do about it.
