CarPlay Disconnecting - iPhone XS Max

My problem is with a GMC truck too. Didn't notice a problem with my wife's 2018 Honda CRV.

I have the same issue with XS max running 12.1.4 on my 2019 A4. It seems many folks are affected yet there isn't a universal solution. Frustrating.

Thanks much. I tried your suggested solution and it worked perfectly. Been using CarPLay without a problem since then.

All I know is after I uninstalled it Carplay get access a lot faster.

Everything works and Heart Radio Pandora and SiriusXM are coming up in full mode.

I have complaining about this for a while thru the Dev Program ..

With no response I may add.

Since I did and upgrade on the iPhone I have not hopped back on the Dev Team.

I have a 2018 Q7 and am having the same issue with my new iPhone XS Max. I checked with Audi and they said it’s an issue with Apple’s software. Highly frustrating. Will try a few of the temporary fixes people suggested here like turning WiFi off but we shouldn’t need to do that to get a $1500 phone to work properly. 12.0.1 didn’t help the CarPlay issues one bit. Really hope they address this soon as it becomes dangerous while driving to have your phone keep cutting out on you.

That is how I see it but I’m not a software engineer. It has been the only solution for me that has produced a result that I can live with. Not happy about “losing” Google Maps but I use Waze on the commute. Still frustrated by this entire experience.

Have a call this PM with Apple support. Hopefully that will go well. They found another problem with the iOS that they needed to work on. Apparently how they collect data from our phones during issues like this is not working correctly as well. So they cannot “see” what is happening.

I have the same issue.

Audi S5 Sportsback 2018

I had an iPhone X and everything went perfect.

Now with the XS max nothing but disconnects.

I contacted apple support and then escalated it. They believe it is an issue with Audi not supporting the phone yet.

I was told I need to contact Audi and let them know.

I think I can confirm on my end, for 3 days now I’ve been using a usb voltage meter and no disconnects. If I remove the meter and plug straight in, it disconnects. It must be some kind of power management issue. 12.1 did not address this either. For those having the same issue, I got a $5 usb voltage meter off of Amazon (Prime shipping too) and that should be a good temp fix to alleviate some frustration until Apple finally addresses this issue.

Haha, well now it looks like it’s $10 but here’s the link of the one I got:

USB Tester Meter, Benss Digital USB Safety Tester Current Detector Mobile Power USB Charger Tester Meter Capacity Current Voltage Tester Meter for For Phone Power Bank https://www.amazon.com/dp/B07GGXZYV5/ref=cm_sw_r_cp_api_yQW2BbJ4176XG

I’m sure other ones will work too, there are others for cheaper as “add-on’s” if you want one for around $5.

I purchased the USB meter and initially things seemed better. If I didn't do anything else but maps, it seemed to stay connected longer than before, but the minute I introduce music or a phone call, the problems still persist. Experienced disconnects on my XS Max and my wife 8 Plus. This is getting terribly frustrating.

I was just asking if anyone had, in fact, contacted Audi. It’s a fair question.

As for the NDA, it absolutely would not be a violation to say whether or not something is being fixed. Please stop lecturing everyone:

Further, Apple agrees that You will not be bound by the foregoing confidentiality terms with regard to technical information about pre-release Apple Software and Program Agreement Page 37 services disclosed by Apple at WWDC (Apple’s Worldwide Developers Conference), except that

you may not post screenshots of, write public reviews of, or redistribute any pre-release Apple Software, Apple Services or hardware.

Did you ask to speak to Tier 2 support or did you talk to a first level support person? If the latter they took your information, a case number was created and it was passed on. Your opinion on how they sounded is irrelevant. I have no issue with someone who has not contacted them before calling and reporting it, or taking it in, and getting a case number generated. But if you have already done so calling again and again, accomplishes nothing other than clogging the system assuming there are enough people to do this. Also posting here accomplishes nothing. Have you also contacted Audi?

I think Apple support is big enough to handle anyone calling from this thread without effecting helping others. Audi won't be helpful here, this is an Apple software issue. Taking the new phone out of the mix (XS Max), my wife's phone (8 Plus) is experiencing disconnects, her phone was fine before iOS 12. So this is a power management issue with larger phones. I for one, think everyone should have a trouble ticket associated with their account/phone, so one, the more incidents they associate with this issue, the more this gets on their radar, plus if they don't resolve this in a timely matter, you have some recourse to swap the phone, etc.

Nope, as I just said, I don't have the issue. My XS Max is working with my BMW. So why is that? What is different about your Audi and my BMW and the phones in question? That is what Apple (and Audi) have to work on. And as I said to the other person if you have not called back and asked to be transferred to a Tier 2 engineer you need to do so. If they ask you to put a profile on your iPhone to test volunteer to do so. Do the same with Audi.

And this is not new, even with Bluetooth connections. The only thing I have seen new here is the "fix" of connecting a meter in the line. But you are dealing with multiple variables in these types of situations, whoever makes Audi's head units may have not completely followed a Bluetooth standard/profile, or something similar, which is causing this issue. Does this mean Apple will quit trying to fix it? No, they want your iPhone to work. They will work with Audi, and whoever made the head unit and try to come up with a fix if it is possible. If the fix has to be on Audi's end they will work with them to try to get that done. But first they have to identify what is causing it. So be part of the solution, get up to the Tier 2 engineers and volunteer.

99.9% sure it’s a power management related issue. I’m now using a USB power meter in my car and haven’t had one disconnect since. If I unplug it, it disconnects frequently. It seems the power meter keeps the current steady and prevents the disconnects. Apple needs to fix this in the software so the phone is telling itself to pull the same amount of power no matter the charge level when CarPlay is initiated. Get a USB power meter from Amazon, they’re cheap and at least a temp fix until they address this.
