Since iOS11 Bluetooth keeps disconnecting

I have had the same issue with my iPhone SE, since ios11. I have done a factory reset, then restored, and none of that lasted. My phone will disconnect from my car if I receive a text or email message, and that happens within seconds. If I try to make a call, it will disconnect from the car, but my phone is still making the call.

I've spent many hours on the phone with Apple, and most of them don't have a clue about anything they can't read, or any idea of trouble shooting outside of what their logs say. I guess you can't blame them for that, but they are of no help with this issue.

I am of the same mind as some others, and even though my hardware is all Apple, it's easier and cheaper to change phones than cars!

I have this issue with an IPhone 5s running IOS 11.4. The Bluetooth device that won't stay connected is a pair of ReSound hearing aids. I paid a pretty penny for these and they are supposed to work as follows: with the correct setting, incoming phone calls are supposed to ring through the hearing aids, and pick up through them. Same with outgoing calls (of course no ring in that case). In this mode, it works like speaker phone except the audio plays through the hearing aid.

But it often doesn't work. On both incoming and outgoing calls, sometimes the call picks up but the bluetooth play-through-hearing aids doesn't work. Or maybe it does and then disconnects during the call. Once in a blue moon, an entire call works without incident.

Now I don't know whether the flaw lies with the hearing aid app for the IPhone or with the IPhone blue tooth implementation itself, but I suspect the latter. The only "solutions" I see offered are turning the phone off and on. I have tried that and found it worked. But that's not a solution. You shouldn't have to restart the phone multiple times a day, and anyway, how can you do that for incoming calls?

Likewise, same problem out of the box with iPhone 8 plus, I’ve had no problems with a google pixel or an iPhone SE that didn’t have iOS 11, problem only happening with my iOS 11 iPhone 8 Plus.

So I was on settings when the Bluetooth disconnected.

What happened was that it completely rests it self.

Hope they fix it ASAP with iOS 11.0.3!

Updated to 11.1 and now tested, not fixed...back to Apple support. Car hands free worked fine for first 30 mins, but now is back disconnecting/connecting.

After upgrading to 11.2 beta no more issues on my X.

Found the problem.

This is happening with a lot of BT ear buds and headphones too. This is not just a car issue. Mine drops multiple times in an hour at the gym. Ridiculous.

Above is where an Apple representative told me to voice my concerns.

He writes for Forbes on Tech issues. He’s told me this should be handled via this community. Haha!!

I was having this issue on my iPad connecting to my iPhone SE until the last release of IOS 11. Problem has now gone away.

Finally my issue seems to be resolved after i got a replacement from Apple. Keeping my fingers crossed. Been almost a week and have not noticed dropped bluetooth connection.
