iPhone 15 Pro bluetooth stutter when connected to a car

My iPhone 15 Pro's audio stutters when connected to my car via Bluetooth. When it is connected to my AirPods or Bluetooth speakers, it works fine. I have checked with other phones connected to my car, and they work fine. I tried resetting my phone in DFU mode, but still no luck. I had no issues with iPhone 14 on iOS 17. I guess this issue is specific to the 15 series or just my device? I see other people having the same issue with the same phone and the same car in the car community.


*** The issue persists on iOS 17.1.1 ***

iPhone 15 Pro, iOS 17

Lossless audio
Choose to use Apple Lossless audio.
This option is only available if you’re signed in as a subscriber to Apple Music.

I am subscriber to Apple Music. Turning off lossless option did solve my problems with streaming music, podcasts or radio via bluetooth.


If you don’t have this option, you cannot turn it off. Hence this should not be rout cause of your problem.


Sorry.


Overall, in my opinion the issue concern the fact that iPhone tries to send more data than actual bandwidth of the bluetooth connection.


Actual bandwidth may be lower than nominal due to interference with Wifi or other electronic equipment in your car or at home.


Bluetooth bandwidth in older iPhones may simply be lower by default than in new IPhones like 15 or 14, so it matches what your car multimedia can process.


Lowering quality of sound reduces bandwidth required to streamed via Bluetooth. Maybe check, if you can change it in settings of your apps.

When your bluetooth stutters (or used to stutter) would the sound pause/stop, then continue where it left off, or would it pause/stop then continue as if it were continuing to play during the silence?


Fortunately I have 3 months of Apple Music for free. Turned that on and now i see the setting. It was already set to Off so I don't know if this was causing my issues. But we will see.


Thank you for the suggestion. Completely deleted my phone from my car (phone and streaming media-wise) and deleted my car from my bluetooth connections list on my phone. Hoping the combination of this and the Music setting will do the trick. If so, I'm hoping that when my free Music subscription runs out I'm not right back where I started with this issue.

Really glad to see that I’m not the only one with this problem.

For me this started with my iPhone 13 Pro and continued after I upgraded to the iPhone 15 PM. For the record I drive a 2015 Honda CRV. CarPlay isn’t an option for me. I updated my phone to iOS 18 and still had the same problem. It actually seemed worse if that’s possible. Just updated to iOS 18.1 tonight so we’ll see if that does anything though I’m not the least bit hopeful.

I’ve tried so many different “fixes” that don’t actually fix anything. This is definitely an iOS issue that, it seems, Apple is choosing to ignore.

In a way I'm glad to see that others have this issue. Looking at the post dates it's been ongoing. I've been experiencing the choppy play with my iPhone 15 pro connected to my Volvo XC60 and with my AirPods A2031 (which is baffling). The connectivity issue with my car started a couple of months ago. Since I work from home it's been an annoyance up to this point. Planning a couple of road trips soon so I would love to get this fixed before then. Hoping iOS 18 fixes the issue. In the meantime...


I've tried forgetting the devices in bluetooth settings, rebooting the phone and reconnecting as suggested in some YouTube vids but that did not work.


Tried reviewing the settings for the Podcast app (use that exclusively in the car) to make sure it was using WiFi and Cellular data to download music but all settings look to be correct.


In paging through the thread I see many with similar issues but, correct me if I'm wrong, no one from Apple sharing a solution. Did see 1 reply but nothing in it touched on car connectivity.

this is simply untrue, you seem to be the only one in this thread that has actually said it worked fine with airpods, while I've seen at least 3 people who said that they had stuttering with airpods as well and multiple who haven't even mentioned / tried with airpods and/or said they had stuttering with any bluetooth device.

As I myself have the same issue with both my car and JBL bluetooth speakers, I'd advise you to at least give it a try.

Same here, I have

Huawei watch fit 3

Nothing Ear stick


the Nothing Ear stick stutters if I connect both devices at the same time, it's boring that when I get a phone call, I need to disconnect the watch 👀, however the Air pods works fine with Huawei watch fit 3. So I think apple's eco system wins here and doesn't let you to connect all these non-native apple BT devices.

After resetting the phone back to factory settings, downloading the apps I had pre-reset and setting things up to my liking I was stutter free...for about 3 weeks or so. Between the time I got it set up and the stuttering started again the only app I loaded was GarageBand and I recreated my lost ringtones.


I've read through some of the updates and see that people tried different ways to connect their phone and that someone suspected the Apple Watch is the issue. I don't recall any of the posts stating that the poster had an Apple Watch (but I may be wrong). I do have 1 and plan on trying the fix posted this week. Anything to keep from wiping my phone again.
