Since iOS11 Bluetooth keeps disconnecting

This idea of a power management issue has echoes of my experience too. As I said before, my connection never dropped mid-call. It only connects/disconnects when it is sitting idle so to speak. I did try my phone both powered and not powered though while in the car which made no difference.

As a slight update in my case, I contacted Apple support direct last week. Gave them this thread link and the support chat confirmed to me they are not able to access the threads directly from support- so I copied my entire problem post into the chat session. The chat confirmed I was not the first person to seek help for similar reasons that day and my case was 'escalated' to a phone call. The usual questions later, a remote support session was established with my phone ( new one on me ) where analytic details from the phone were collected by Apple while I was connected to wifi. The slightly disappointing end to this wizardry was that I should factory reset the phone using itunes which I have duly done. The assistant advised that the conclusion to the analytics was only that hardware was not at fault. Unfortunately I'm away on business and cannot try it out in my car or any other device.

Come you clever engineers; you've had bluetooth working before!

Just had problems with disconnecting again myself so looks like I jumped the gun thinking it actually worked for me. It only happens with my car Blue Tooth. I contacted Apple Support and they suggested that I look for a firmware update for my car but this is an Apple problem, not a problem with my car.

Unfortunately I don't believe that a factory reset is going to fix it. My son set up his phone from scratch, not from a restoring a backup, and in my Accord he has the same problem, but in his car with a Pioneer CarPlay head unit he does not have the problem.

The new ios update definitely messes up bluetooth on the phone. My touch5 works great on a speaker that my I phone disconnects from, replaced the I phone with a new one and I am getting the same problem. Both I phone 8 purchased new, on IOS 11 are having the problem

Installed iOS 11.1 b5 on my iPhone 6S Plus - although general performance and battery life seem to have improved significantly, Bluetooth disconnected after 15 minutes in the car this evening. The phone wasn’t doing anything else, just playing Spotify, no other apps open.

I was feeling hopeful about a solution since some of you are saying you don't have problems after the update but I updated to 11.1 yesterday and unfortunately, I still have connectivity issues in my car. This is only happening in my car. All other devices don't disconnect like this.

Waiting for next update to truly fix this for me. 😢

Same for me. 11.1 does not fix the issue for me with my car as well. The difference now is that disconnecting is much more random. It could be within seconds of connecting, or it could be minutes. Longest connection I have had was about 5 minutes. Shortest was about 2 or 3 seconds after connecting. Connecting seems to happen within a second or two of disconnecting, which is an improvement over what it used to be. Sometimes it could take a minute or more to connect again after disconnecting.

It’s definitely iOS 11. I have two iPhones, one for me personally, one for work—both on iOS 11.0.3. Both indiscriminately disconnect from BT in the car. However, my Android tablet stays connected to BT in the car with no problem. Apple needs to get on this right away!

Okay, don't want to jinx anything...

I noticed that my FitBit Charge HR was also connected by Bluetooth whenever I turned Bluetooth on. So I was connected to two devices - my speakers/headphones/car and the Fitbit.

I couldn't disconnect Fitbit, so I clicked "Forget device" instead. Almost two hours later, no disconnect.

There's still an issue, because this essentially means I can't use my Fitbit. But right now, I'm enjoying listening to music without constant disconnects.

yes its an issue with iOS 11

as usual, Apple does not admit there is a problem but they are probably aware.

my bluetooth devices work fine when connected to my Android devices.

when connected to my iphone, it starts stuttering is the phone is too far or if i pass between the phone and speaker

This is crazy. Is there somebody at cupertino who can read these posts and solve the problem? My iphone 6s since upgraded to ios11 works as cheap chinesse toy with my Audi bluetooth - connect, disconnect, connect, disconnect.

I am really disappointed and expecting update which will solve this problem!!!!!

or should I go to samsung store.... please advise

Well I got tired of this problem. Can't use my phone for work, so I pulled out an older 16GB Google Nexus 5X from my spare phone collection. It updated to the latest Android Oreo (8.0). Actually quite pleased with it (over my iPhone 8 Plus; 256GB) and may continue to use it for quite a while longer even after Apple fixes this problem. Go figure... $200 current phone vs $1000 iPhone.

Same happens to me since upgrading to 11.x. Happened on my iPhone 6s and my older 5s. Drops all bluetooth connections - my jambox, beats headphones, and Ford Mustang. Drops ever 1-5 mins, then automatically reconnects. Super annoying.

I have a 2015 Lexus and my iPhone 6+ has had a rock solid connection to Bluetooth. After upgrading to iOS 11 every 20 to 35 minutes the phone disconnects and reconnects. It does the exact same thing on my 2015 Toyota Camry and our 2010 Sequoia. I have deleted the phones in the car and the connections on my phone...I have reset the network settings ion my phone but it doesn’t seeem to make a difference. The disconnections are consistent.

I am seeing a lot of posts on this forum for the same

Issue. Is there a workaround. Is this big being worked on.

I have this problem with iPhone X and iOS 11.0.x/iOS11.1 the Toyota Touch 2 and Go system. Let's hope that Apple can sort this pretty quick. Encouraging that there is at least a Beta of 11.2 around which may have fixed the problem. Very annoying for phone which costs £1150 (256GB)!
