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...

Seriously it sounds like ******** to me. Such disappointment coming from Apple. When i was using iPhone 6s, when i was still on iOS 10, my Android Wear smartwatch and my bluetooth headset connection was stable. Until i updated the phone to iOS 11, my Android wear watch started to keep disconnecting but my bluetooth headset was stable.


So I thought maybe changing to the latest iPhone X could improve the situation. I was **** wrong. Now it is the other way round. My Android Wear watch connection is stable and my bluetooth headset keeps disconnecting!

Iphone 6s user. Bluetooth connected devices:

1. Samsung Gear S3 - everyday use

2. Apple Watch (momentarily no longer connected)

3. Bose Soundsport wireless headphones - heavy everyday use with apple music

4. Plantronics Voyager - office heavy everyday use


All these devices randomly disconnect ever since IOS 11.2 update and the problem is still unchanged through 11.2.1 and now just recently 11.2.2.


Music headphones (Bose Soundsport Bluetooth)


My Bose bt headphones disconnect in two ways:

A. The music stops and the just starts again with a click in my headphones, this being the happy scenario!

B. The music stops, and then the headphones message me: “Disconnected from iphone” and in about 1-2 seconds it reconnects, letting me know it did so “Connected to iphone”. This is the bad scenario as apple music hits STOP on headphones Bt disconnect! So I have to go in and restart the song!


Plantronics Voyager bluetooth headset!


Now, I heavily use this headset at the office and speak to people on the phone with both my hands free! Lately (as I explained above, from 11.2 through 11.2.2) it drops the Bt connection randomly in the middle of a call! Sometimes I am away from the desk (surely within Bt range, about max 2 meters) and it just drops, but as opposed to the Bose headphones it dooes not automatically reconnect! Needless to say it’s annoying!


My Samsung gear S3


Everyday smartwatch which emplys two Bt connections with my iphone 6s! Randomly it vibrates to tell me it disconnected from the phone! This is not critical but it goes to show that it is a problem with pretty much every Bt device!


Clearly after reading this thread, this is true!


Lately I have noticed something that unfortunately I cannot substantiate with clear proof! If no app that transfers data is loaded in memory, bt connections do not drop! The moment I use any browser (so far tested only over wifi) the drops begin and are consistent enough to be annoying!!!!


Needless to say that I have tried ABSOLUTELY every solution posted and finally ended up even wiping everything and restoring as new iphone, clean, without even restoring my backup! Just reconfigured everything again and installed apps as I realized I missed them! Same crap!


My desperate hope is that apple knows this! And will perhaps fix it the 11.2.5 build!


I know people (at least 4 immediately related to me) with similar issues ... so I can safely say it happens on iphone 6s and iphone 7


I also have friends and acquaintances that own iphones (6, 6s, 7 plus and X) that said they do not have these problems on 11.2 through 11.2.1, but they are not heavy Bt users! At most they have a smartwatch connected so it’s possible that they have not noticed since it quickly reconnects back!


I also have a friend that thought his iPhone 7 was broken physically but as he talked to his colleagues (also iphone owners) realized that it’s an issue with ios 11!


Also, offtopic, wifi works like crap! It does not drop the connections but it just does not transfer data! Dies not even show a timeout! The progress bar ia just stuck! Lucky though I can use my 4g which seems at least so far to work properly!

been having this issue as well and was tearing my hair out to get the iphone to keep the connection with my car. I noticed that the bluetooth connection was being interrupted by any other activity happening on the phone (i.e. if a notification popped up, or message, or maps on siri.)


The only "workaround" that I have managed to figure out is to:

1. Switch your phone to airplane mode

2. Turn bluetooth on


As long as there is no wi-fi or cellular activity in the background to interrupt the bluetooth connection it is holding a constant connection with my car.


I cant receive calls on chat on handsfree while driving...but at least i can listen to my music without being intereupted every 30 seconds!!!!


Guess the "Apple just works" slogan is fading away pretty quickly!!!
