iPhone 15 Pro Carplay disconnects

I did some more googling and found that other users that had the same issue fixed it by getting new cables and making sure that they were “data transfer” cables and not just “charging” cables. I didn’t realize there was a difference. I’ve ordered a new cable, usb to usb-c data transfer so we’ll see if that fixes it. I’ll keep you posted.

I ended up finding my Samsung USB-C from the before iphone time. And it actually keeps CarPlay connected. Just went for a 45 minute drive....bumps...dips....funny looks....picking phone off mount to do something....stayed connected.

Looked up my amazon history and it was this one https://www.amazon.com/gp/product/B071G2XT6M. YMMV but I'll be ordering another.

Pretty annoying that something that SHOULD have some standards and consistencies like a cable/connector...can cause such grief.

Ok, I waited about a keep to post this to make sure it worked.

details: 2019 VW Tiguan SEL with wired connection for the CarPlay with an iPhone 15 Pro.

i tried everything suggested here but nothing worked, and at the end I purchased from amazon these wires CONMDEX USB A to USB C 10Gbps (1ft, 2-Pack) USB 3.1 Gen 2 Short Data Transfer Type C Cord, Fast Charging Carplay Android Auto USB C Cable for iPhone 15/15 Plus/15 Pro/15 Pro Max, Samsung Galaxy S23 https://a.co/d/7smJjH2

Now finally CarPly works again

Solution:

Over recent weeks I have been having problems with the well documented issue of Apple CarPlay disconnecting often at the most inconvenient times.

I tried all of the online suggestions to try to fix it, clean the lightning port, new cable, restart the phone, firmware updates all up to date etc. etc. but, nothing worked.

Something I noticed however was that my phone kept repeatedly pinging like it does when the charging cable is first inserted but it was doing this after CarPlay crashed and I was getting a USB connection error message. What I also noticed was that despite my phone being plugged in for some time it wasn’t charging as it normally did was usually sitting at around 78% charge.

So, I had a good study of all my phone settings and eventually came across “Optimised Charging” under “Battery”. In a nutshell this is intended to prolong the life of the battery by learning your personal usage and charging cycles and only charging the phone to 80% until it considers you are going to be using your phone shortly and it recommences charging to 100%

Anyway, this afternoon I turned this optimisation off and CarPlay has worked faultlessly for over two hours when before it was crashing every ten minutes or so.

My question therefore is, could there be a bug in OBC introduced in a recent firmware update that causes the disconnection from CarPlay when the phone’s charge approaches 80% because it never used to happen.

Thanks.

iPhone 15 Pro

This and other posts about battery level have lead me to a possible cause for the issue and a solution. At lower battery levels the iPhone 15 Pro tries to fast charge the phone demanding more power than a USB-A port can supply, causing the USB-A port in the vehicle to reset and cause the disconnect. At a higher percent charged, the phone slows down the charging rate and also the power required.

I have the constant Apple CarPlay and charging disconnects when my battery is below 60% using a USB-A to USB-C cable. In my vehicle it does have two USB-A ports. If I use a dual USB-A to USB-C cable (https://a.co/d/02GB6jQm) the problem goes away with the extra combined power. I realize this doesn't help those that only have a single USB-A port.

There's a graph shown here https://www.chargerlab.com/charging-review-of-apple-iphone-15-pro/#:~:text=The%20charger%20can%20charge%20the,Max%20due%20to%20battery%20capacity. of how the iPhone Pro reduces the power used during the charging process.

Different vehicles may have different USB-A maximum power capabilities which may affect how far charged the iPhone Pro needs to be for it to work without constantly disconnecting.

Iphone 15 doesn't use a lightning cable.. it's USB C. Using the Apple USB C that came with the phone constantly disconnects..

I happen to have a USB C to USB C Thundebolt 3 cable and guess what? IT WORKS! So when you are using Spotify, Maps, Making a call, etc... you are moving alot of data across that wire and a 480Mbps chokes on it.

Verified working solution for me was cable replacement:

Vehicle 1 - 2019 Acura TLX w/ wired CarPlay

Vehicle 2 - 2017 Honda Pilot w/ wired CarPlay

Previously both vehicles exhibited the disconnect issue frequently. I was able to duplicate the issue consistently by running Apple Music + Maps + active phone call. I tried the following cables:

1) Cable packaged with iPhone 15 Pro Max + USB C adapter - BAD

2) Nintendo Switch cable - BAD but better. Stayed connected for 10+ minutes before glitching

Replaced with:

CONMDEX USB C Cable [3ft, 2-Pack] 10Gbps USB 3.1 Gen 2 USB A to USB C Data Transfer Cord purchased from amazon. USD $13 for 2-pack

I just drove for hours with everything running and had zero issues.

Good luck!

Both my wife and I have an iphone 15 pro and in both our cars apple carplay keeps disconnecting.

I never had this issue with iphone 14 pro or 13 pro.

I have tried multiple caples without anything working.

Apple support recommended their usbc to usba converter together with apple usbc caples, but that didn't work either.

I have also tried wireless with Carlinkit 5.0 2Air but it still disconnects.

Yesterday I tried a wired connection but with an iPhone 14 Pro, and it never lost connection.

The issue must be the iphone 15 pro, and I don't get why apple doesn't fix this.

Both iphone and car has the latest software update.

OK as a couple of others have mentioned I FINALLY FOUND A CABLE THAT WORKS

For $8.99

CONMDEX USB A to USB C 10Gbps (1ft, 2-Pack) USB 3.1 Gen 2 Short Data Transfer Type C Cord, Fast Charging Carplay Android Auto USB C Cable for iPhone 15/15 Plus/15 Pro/15 Pro Max

As soon as I plugged in my Phone, my car switched to CarPlay automatically--which never happens. Then I used CarPlay for over an hour with no disconnects.

Note this cable is quite stiff so you might want one longer than the 1-ft cable above so you can rest your phone flat.

It also charged my phone quickly from my car which was very surprising. (I had assumed my car port was a slow charger, but didn't seem so with this cable.)

I was so frustrated I vowed to never get a non-wireless CarPlay car again, but now I don't have to worry about that.

Ford Mustang here, having this exact same problem. I am noticing it is disconnecting mostly when I wiggle the base of the USB-C, not the phone or the base of the USB connection to the car. What has been working for me (so far) is a cord that has the BASE of the USB-C cord a bit more secured, like this: USB-C to USB A Cable

I hope this helps in the long run but has been helpful so far.

Update: here’s the cable that worked for me. I’ve had no issues with it disconnecting. I’ve had it a few days now.

There could always be more than one issue, but I am sure the problem I have is related to the % of charge on the phone. When my phone is charge higher enough (usually 80% or above), I never have the issue. When the charge is below 50% it is abosolutly going to happen. I have waisted some time trying to figure out the exact % where it breaks, but I haven't pinpointed it yet. I think it is somewhere between 60-70%.

iPhone 15 Pro Max

stumbled across a thread which said battery needs to be over 50% charge.

since I have been plugging phone in with good battery left, I have had no issues.. not sure why it is an issue sub 50% and whether that is the threshold.

anyways something for people to try if you come across this thread

Ok, I did everything it was suggested by Apple AI (geeks) and posted by their victims. I’m not sure if this will continue to work but I tried and connected my unlocked 15Pro via USB C to the USB A in my 2019 Tiguan and than started the car. Did it the last four times and worked every time. I hope that’s it. I’m already sick of this $hit and Apple is not saying anything.
