iPhone 11 on iOS 13 having Bluetooth connectivity issues

I cured my 11 by doing a full restore from iTunes. Not the cloud or another phone or pad. Otherwise you could be copying the error. I pulled the lead when my memory was empty then reconnected for full restore. That way no old program was in my phone. Good luvk

Be sure to delete your connection from both your car and your phone and then re-pair.

Sometimes configuration information changes between iOS releases and it can confuse the head unit.

SOLVED - Upgraded software to 13.1, re-paired speaker now working fine

IOS 13.1.2 release, addresses issue where Bluetooth may disconnect on certain vehicles. I have not had time to install and test.

I too have this problem with a new iPhone 11. This was to be a replacement for an iPhone X (on a trade in deal). My Bluetooth device is a Plantronics PLT E80 series. The iPhone X is rock solid with this Bluetooth for both iOS 13.2.3 and 13.3. The iPhone 11 disconnects after between 30 seconds and a few minutes. Makes it pretty much worthless. It did this for both 13.2.3 and 13.3, which seems to show its not really iOS related but tied to the actual 11 hardware somehow.

I called Apple and after a series of tests, they determined it was a phone problem. They are sending a new 11 in a few days. We will see how that one does. If it faults as well, its going back, and I will just keep the iPhone X for now and punt on the 11 plan.

I have an iPhone 6s . I have been facing this issue after I upgraded to IOS 13& also persists after upgrading to iOS 13.1. The only way around I found is that rather relying on auto connect.. I got to bluetooth under settings and click on the particular device and connect it through settings on iPhone. Then the connection sustains. But yes auto connect doesn’t work and disconnects after few seconds

It is rather odd, Bluetooth works 100% with my AirPods, Anker SoundCore speaker and JBL Go 2 speaker. Yet, sometimes it won’t connect to my 2014 Dodge Dart Uconnect 8.4 radio.

I turned off “Hey Siri” and now it connects 90% of the time. Disabling that also eliminated the pops and crackles during phone calls made in the car through the Bluetooth connection.

Maybe try disabling “Hey Siri” as a workaround until Apple fixes the problem?

Mine seems to be resolved with my iPhone 11 Pro Max and Plantronics PLT_Edge bluetooth headset after forgetting on iPhone and then repairing. It is no longer disconnecting after 60 seconds or so. I had paired this headset initially with iOS 13 when I received the phone and then updated to 13.1. I have also paired my 2016 Jeep Wrangler Uconnect after updating to 13.1 and have had no issues there either.

As I mentioned before I think I fixed it

1. backup to computer using iTunes
2. restore iPhone as new - not from backup
3. when iPhone is new again, restore from the backup you did on your computer using iTunes.
4. remove Bluetooth pairing from iPhone and vehicle and then repair.

i have been driving around in my wife’s Mazda now for 30 min or so with her phone with no dropouts.

if it disconnects again I’ll repost

My 2018 Highlander seems to work fine now after updating to 13.1.1.

After the update, I first deleted all paring information from both my iPhone and Highlander. Disabled the BT on iPhone. Restart both iPhone and Highlander and then repair them.

I tried everything I could think of to connect my devices to Bluetooth with no luck (on iPhone 11 pro). I realized I still had Bluetooth turned on and my devices connected to it on my old phone. I turned off WiFi and Bluetooth on the old phone and my iPhone pro immediately connected to those devices. So for me it was having Bluetooth turned on with the old phone that was the issue. It works beautifully now.

As Apple support were not helpful I got onto a FitBit forum. The suggestion, if you have your old phone, is to open its Bluetooth and forget all devices then switch Bluetooth off. Then go to the new one -- and for me - hey presto they all paired.

Just spoke with an apple support senior advisor in regard to why SIRI disconnects from the car radio. My Toyota radio needs a

FirmWare update usually via the dealership. Apparently an older radio requires a newer version upgrade in order to properly operate and to be in sync with the latest software.

So I've been having this exact problem with my Jaguar XE (2015) and my iphone 8 ever since upgrading to iOS 13. I have tried all manner of fixes. Deleting Bluetooth connections, repairing the car to the phone and nothing worked. I found that audio will play fine in the car if connected by USB to the car and after twenty minutes of this the connection would be stable again for bluetooth, but who wants to be doing that all the time to listen to music or make phone calls whilst driving...

I booked my car in with my local dealership and ended up paying an annoying amount of money to have the cars firmware updated to be on the latest version as that was the only thing I could think of left to do was the cars bluetooth software. Since Jaguar updated the cars firmware with the latest version my iphone is now connecting find for music and calls and haven't had a drop since yesterday. Annoyingly Apple released 13.1.2 (Addresses an issue with bluetooth connecting to cars) after I paid money to get my car updated....

In iOS 13 apple changed it's bluetooth privacy settings, which is why some people may have noticed some apps asking for bluetooth access. I think it's the same thing with Cars being paired to the phone, it's requesting something the car can't agree to.

Please let me know if iOS13.1.2 fixed these issues for you all.
