iPhone 11 on iOS 13 having Bluetooth connectivity issues

An update on this issue for me. I never got my "11 Pro" to the point where it would reliably pair first time with my 2008 Audi. It would pair quickly, hold the connection for a minute, then drop it and refuse to pair until I manually selected the car in /Settings/Bluetooth a couple of minutes later (why a couple of minutes were needed I don't know). After that the connection stayed up and I never had a problem. So it was frustrating, but I could live with it. I never had an issue with other BT appliances including AirPods, Beats, BT in our 2012 VW, Jabra BT speakers etc...

I have since disposed of the "11 Pro" and bought a "12 Pro". This works first time a charm. No issues at all. Just like my old "X" and the iPhone I had before that.

Net net is that there seems to be a hardware/firmware issue on the 11 which causes issues with older (legacy) BT stacks. The "12" has fixed the problem.

Installed IOS 13.3.1. Now Siri audio is working in my 2015 Subaru Outback. Before Siri executed the command, but I heard no audio over Bluetooth.

I just updated to 13.3.1, which fixed the issue for me. I can now hear Siri when I'm sending messages via bluetooth in my car.

i Have same issues with sound on bt headset. turned off my apple watch. problem gone. useless apple watch now :O

Since I disconnected my Fitbit (Foreget this device in Bluetooth) and the only device my iPhone 11 is paired with is the car it has worked well for 2 days now with no issues or disconnects.

14.2 has fixed my 11

While this is not the best solution, it is somewhat better than nothing. I turned off my wifi before getting into my car and it now works. I can use my cell hands free and it no longer disconnects every 30 seconds.

At the beginning of this thread i keep reading about replacing phones and car headsets. I really don't want to go through all that and still have the same problem.

again not a solution, just more “tolerable” way to where i can now use my phone.

I've had the same issue but mostly when I have my Apple Watch on...I had the best Apple Tech and she said to unpair the iWatch then repair and it worked. I hope it lasts...I can now connect my iPhone 11 via Bluetooth to my car...

(Reporting back with results as requested).

This update appears to have also worked for me (iPhone 11 Pro Max).

I followed the exact steps utilized in previous attempts (forget device on iPhone, reset network settings, turn phone off, approach and enter vehicle, delete phone from vehicle, turn phone on, re-pair vehicle/iPhone).

A few things to note:

The “pairing” phase occurred much faster for me this time (it would previously require multiple attempts before MB would even recognize this iPhone). The recognition occurred on the first attempt...and quickly.

Secondly, I did not sync contacts (per previous recommendations).

Thirdly, I wanted to attempt this without adjusting any U1 chip settings. So left as is.

Tested for approximately 15 minutes and not.one.drop.

Its a Christmas miracle ... albeit a bit late ;-)

I had the same issues as all here and I’m an old Apple user who is still learning the obvious. We still have our old phones in the house. After unpairing the BT devices from our old phones, they showed up on our new 11 pros. Hope this helps at least one person.

I also have random Bluetooth dropping problems since upgrading my phone to an 11 pro. I drive a Tesla model 3 which uses Bluetooth from the phone as the primary car key. Never had any problems with my old iPhone 8 or my wife's iPhone X. However as soon as I upgraded to the 11 pro I started having problems getting into the car.

Many times I have to manually wake the screen on the 11 pro to "awaken" Bluetooth functionality. As soon as I wake the screen the car door will unlock, every single time. Before the 11 pro I never had to do this. It's almost as if iPhone 11's turn off Bluetooth altogether in order to prolong battery life. Extremely annoying.

Another person posted this and it has also worked for me.. I powered off my watch and left it powered off the last week and i have not had any stuttering while on my iphone 11 using my AirPods.

So basically my $500 watch prevented my $250 headphones from working with my $1000 iphone..

THANKS APPLE .. WHY DONT YOU FIX THIS!!!

I have a solution!

I had no issues with my older phone and once I got my brand new iPhone 11 Pro, I couldn’t hold a Bluetooth connection! We trouble shooters multiple things. Apple Care told me that my “back up may be corrupt.” So finally, as a last resort, I ERASED my phone to factory settings! Once I tested the Bluetooth in my car again, it was perfect. It held the connection! Once I tried to reload my “backup” info back into my phone, the problem came back! He was right! Somehow I had a corrupt “backup.” It sounds ridiculous, but it worked. So I have an empty phone that works perfectly on Bluetooth. Bittersweet! Save your photos and notes in iCloud. Use Google Photos if you’d like. This way you can have them easily accessible through your factory reset phone!

After the iPhone is send to Apple they did some diagnostics and returned the iPhone with the message: cannot reproduce.

Funny part is the issues are gone, it looks after 2 weeks no connection drops anymore. I believe the resetted the firmware because when I send it it was installed with the beta 13.5 just to see if that version fix the bluetooth issue, when I got it back the 13.4 was installed. So after half year frustrating phone calls in the car, not able to use watch as it should be now everything works.

It has to be a newer Android phone, like a Galaxy S20+.

Older Android phones work just as older iPhones do.

I know the following cars work perfectly with Bluetooth and an 11 Pro Max, or at least they did with mine:

• 2011 Toyota FJ Cruiser
• 2019 Chrysler 300

Along with the following BT devices:

• Apple AirPods Pro (firmware 2B588)
• Denon D-M41 Micro Desktop Stereo
• Jeff Lynne's ELO Portable Mini Speaker (Unknown manufacturer, came free with a ticket package)

It's very important that you delete all BT associations from both your phone and your device and try re-pairing, an don't forget to power cycle the device.

I had an issue where suddenly I could no longer pair with my Denon stereo, no matter what I did, until I unplugged the Denon from the wall for a few minutes and plugged it back in, and my phone paired right away.
