Since iOS11 Bluetooth keeps disconnecting

Since I upgraded to OS11 my iPhone 6 keeps disconnecting from the Bluetooth in my car, a Mazda 6 2015 vintage. To reconnect I have to select the phone on my cars infotainment unit and off it goes working for a while longer until it again disconnects mid song. This didn’t occur prior to OS11, any ideas?

I had the same problem with my VW Sharan and it‘s „professional“ hands-free. I tried every update after 11.0. Apple support was not helpful at all, essentially suggesting I look for firmware updates for the car. As if the car hadn’t been working just fine until iOS 11 came along.

Anyway, after upgrading the phone to 11.2.1, I have not had any more disconnects. Knocking on wood that it stays that way...

Looks like 11.2 did the trick for my iPhone 8+ in conjuction with my car's Kenwood and a couple Plantronics headsets. No more random disconnects during business calls.


However, I must say this experience forced me to evaluate Android devices. I had an older Nexus 5X and also found a Black Friday LG G5 for $200 (w/ expandable microSD storage up to 2TB). Android has certainly bridged the gap closer to the performance and stability of iPhone at a fraction of the price. Once we're ready to retire our iDevices, we'll be looking elsewhere unless Apple comes down in pricing. Doesn't make sense to spend a grand anymore even with subsidies. There's only so much you can do to improve the phone. iPhone X features are nice, but after about 5 min, was perfectly fine reverting to an 8 plus.

I am having the same trouble with all my Bluetooth devices using iPhone 6plus since updating to iOS 11.2. Quite frankly every time I update I seem to have this problem, it did it in iOS 11.1 too. Also my music continually reverts to Shuffle when I want it to run through alphabetically, very, very annoying. Can’t understand why they have to stuff around with this!!

You can add me to that group. I actually skipped the 11 update until the 11.2 was available. Been dropping bluetooth on my Acura MDX bluetooth a lot since i updated. Sometimes I can listen for 10, 15 mins? Other times it drops every couple mins. In my case, the bluetooth automatically reconnects and resumes playing, but sometimes I loose the steering wheel controls when this happens and would have to actually handle my phone while driving to change a song, etc. I don't talk much on the phone so I haven't seen the issue happen with bluetooth calls yet. Its very annoying, particularly when using navigation apps like waze 😟

Add me to the list as someone who's suffering the same problem.


Mazda cx9 / iphone 8 / iOS 11.2 here. Worked once and now Disconnects and reconnects every 90 seconds or so when playing music ,Pandora, podcasts, etc . Interestingly enough I can make phone calls just fine thru the car Bluetooth link. Just not play audio


Phone pairs and works well with Jabra headphones. Seems to just be the car this problem exists with.


I've tried all the things others have.... Resetting network settings, re-pairing, etc. Seemed to me to maybe be the contact sych causing the issue so I tried disallowing contact sync when pairing but it didn't seem to matter


Hope the fix this soon very annoying used to work perfectly with my old iPhone 6s

It would drive you crazy wouldn't it? I even contacted Mazda Europe and they said they can't help as Mazda 5 stopped selling in 2014 and they've stopped testing the tech with new phones. I don't understand how it all works as like you said, phone calls work fine, connecting works fine - it's just playing music or using sat nav apps, (apple maps, google maps etc). How can one work fine and not the other?


It's driving me bonkers! I spend so long in the car I just want to listen to music and follow directions. If it isn't fixed in the next beta I'm giving my new X back under warranty as a defective product and buying an Android.

How they manage to break so much during releases I'll never know!!

iPhone 8

iOS 11.2

2016 Lincoln MKZ with "Sync with MyLincoln Touch" - latest version according to Lincoln's "Vehicle Health Report" diagnostics.

When on a voice phone call, the Bluetooth HFP (hands-free protocol) connection between the iPhone and the car will repeatedly disconnect and reconnect resulting in the other party experiencing about 15 seconds of "dead air" during which they continue to talk while unaware that I cannot hear them. The time interval between episodes appears to be random and unrelated to anything else. Since the use of hands-free is a legal mandate in my state and the use of headphones while driving is a safety issue, I have little choice but to seek a resolution to the problem.

Streaming audio which uses A2DP (advanced audio distribution protocol) works fine.

My LG Tone HBS912 (Bluetooth 4.1) works fine for both calls (HFP) and music (A2DP).


I went to the Genius Bar yesterday and although the techs had "heard of" the problem, they had no definitive fix. I allowed a tech to do a factory reset on the phone through iTunes and then did a master reset on the Sync system in my car. I then paired phone to car and tried again. The call disconnected / reconnected about 3 minutes into the call. About 2 hours of total time wasted in that effort.

My *guess* is that the Bluetooth 5 on the iPhone 8 (and X) is not fully backwards compatible with some Bluetooth 4 devices. Users will perceive this as a phone problem since prior iPhone models worked fine in their car, and rightly so. The auto manufacturers will not likely pursue a fix since they, too, will see this as a problem that Apple created and Apple should fix.

Thus, we wait for a permanent fix from Apple.

I, too, went to the Genius Bar, and they gave me the same song and dance. The funny thing was that there was a man next to me complaining about the same problem. The Genius couldn't even establish a connection with the Beats Pill. He was able to establish a connection with another device and then told me that he could not duplicate the problem and it was probably my phone.


As soon as I got home I called Verizon and ordered a Samsung Galaxy S8+ I have had it with Apple. iTunes *****, and Apple Music leaves a lot to be desired. Worst of all, Apple still refuses to admit that there is a problem with their Bluetooth implementation with iOS 11.2. Steve Jobs is rolling over in his grave.

Chalk up another one to this same issue. iPhone 6s and ever since moving to IOS 11 (all the way to 11.2) I have frequent bluetooth disconnects. In the car it disconnects and then reconnects, but on other devices the music just stops playing and I have to hit play again.


This happens in the car, on a CoolStream Duo, Coulax Headphones, and a Magicbox ... so I don't think it's the hardware. It never used to happen at all in IOS 10. This is my first iPhone and I used to love it, because it just worked ... but now all the bugs in IOS 11 are driving me crazy.

I am up to iOS v11.2.5 on my iPhone 6s and I still drop off of both my car (2015 Prius) and Anker Bluetooth headphones. In my car, bluetooth will disconnect and the screen will say "STOPPED". I then have to either reconnect, if lucky, or disconnect from the car and re-connect. When I'm on a treadmill listening with my earbuds, it just stops and I have to reconnect. This happens intermittently. Sometimes it's a couple of hours between disconnections and sometimes it's minutes.


Another thing I noticed is voice navigation through Maps, Google Maps, or Waze doesn't work as it used to. I either get no sound from the navigation or it talks over my speakers like a voice call, then whatever I'm listening to stops and I have to manually start it.


This is beyond frustrating.
