iOS 18 Bluetooth Connection problems

Hello,

I recently upgraded from iPhone 12 to 16 pro. Since the switch I cannot get my phone to pair with my 2019 Cadillac XTS. The blue tooth is normally easy to setup. The car also has a USB connection and although it will charge the phone no other service work (Apple Car Play). Hopefully Apple can make updates/repairs to fix this - my upgrade feels more like a downgrade.

i've had issued since ios 18 public, still on 18.0.1, but not like yours, my airpods stay connected, but whenever i stop using them, when i try to use them again it doesn't connect to my phone, i need to stop bluetooth and start it to get the airpods to work. also brand new airpods 4, and it happened to my girl on her ipad. very frustrating

Hi! Turning OFF the "Vocal Shortcuts" (Settings\Accessibility\Vocal Shortcuts [under SPEECH]) helped with the issue of Bluetooth Audio turning off and on a split second. Fixed BT issues for CarPlay as well.

HOWEVER, after updating to 18.0.1 fixed the issue for myself with "Vocal Shortcuts" enabled. Hope that helps.

EDITED: Thanks, this worked for me. Updated to 18.0.1 fixed the issue with Vocal Shortcuts enabled as well. HOWEVER, when Vocal Shortcuts are enabled, CarPlay is still pretty buggy. I can't switch between Apple Music and Radio. When I try to switch to my car's Radio option, it says, "Feature Currently Unavailable." Seems like Apple Music is "hung-up" during the switch.

since update bluetooth connection to my hearing aids is unstable during phone calls • disconnecting and reconnecting several times a minute • hopefully fixed soon • did not occur prior to update with same devices

As reported earlier, my problem is with the bluetooth connection to my hearing aids • I tried two of the suggestions given (turning Vocal Shortcut off and resetting network settings) without result • hoping the next update will solve the issue • thanks

My phone to my ear buds suddenly has started to break up. I can’t have my phone in my pocket sometimes … I’m talking gym ware clothing. If I move around my small nyc apartment the blue tooth has suddenly started to break up to speakers. NOT BUYING A NEW IPHONE to fix this bs

Hi I’m Jose and I was just wondering can I get the update on iPhone 15 pro iOS 18 version Safari please grant me access and if you’ll be sow kind of keep me informed of the newest update I need it to be installed asap as soon as possible and with your support I’ll be very grateful for it thank you for you time have a good morning by the way

Not sure where I saw this, but a soft reset seems to clear the Tesla key problem (touch and release volume up button, touch and release volume down button, then press and hold the on off button until the Apple logo appears). I've done this twice so far, once per day, and ... so far... things are working. The soft reset clears memory, so it may be something in iOS 18 (or 17) has a memory leak.

This is very annoying and so typical of ios updates. I just bought an iwatch and was told I would have to update my iphone from ios 17 to 18.0.1. I did this, the watch worked fine via bluetooth, but any other bluetooth appliance I had be it headphones or soundbar was not recognized by my iphone any longer. I spent a good 90 minutes with apple support and finally got some of the things to work, but not the Polk soundbar which I often use as a speaker for my iphone.

I posted about my issues with Cadillac XTS issues about a month ago. I cannot connect my phone via Bluetooth or USB. Every update I cross my fingers but still to luck. So I basically don’t use my phone while driving and have to listen to FM radio like I did as a teenager. My “new” iPhone is a disappointment.

SUCCESS! Try this 2 step process: Recycle "Airplane Mode" and then recycle "Bluetooth" on your phone. Then try pairing your SONY Wireless Headphones... It worked for me after trying all types of things....

this worked for me

 Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings. 

This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

Having issues with choppy audio connection when playing music through Bluetooth in my 2012 Mercedes. This was never an issue until I upgraded to iPhone 16 and iOS 18. Music breakers up as if there is a buffering problem. This happens intermittently.

Everyone who is having the issue of Wifi/Bluetooth not turning on. I believe its an issue with 18.1.

please try removing your simcard and then resetting network settings it should work.

i had same issue with my 12promax but after removing sim and resetting network settings it worked.
