Bluetooth connection issues on iPhone 16 Pro

just upgrade to the iphone 16 pro and bluetooth is stuttering with any devices, and doesn’t want to connect 90% of the time. Carplay, Garnin, Headphones.


I’ve tried turning off bluetooth, hard reset on the phone and still no luck….

Interesting! Are you talking about the "Bringing Devices Together" toggle under "Start Sharing By," at Settings → AirDrop, or was it something else?


I'll have to play with this. (If I recall correctly, iOS 18 added "Tap to Cash," etc., right? Maybe that setting was changed to on by default to support new features like that, when they involve holding two phones together.)

Found the problem, if you guys did choose to setup your iphone from a backup or from your old iphone then you all will get the dame issue, if you did setup as a new iphone then you wouldnt have gotten the bluetooth issue, there is a fix, just go to Settings-General and then scroll down to reset iPhone and then choose Reset network setting, after that phone wil reboot and your Bluetooth will work as it should be!

I spent over an hour on the phone with two different Apple techs on this issue (pairing my old Bluetooth items with my new iPhone 16 Pro) yesterday. It turns out it doesn’t have anything to do with your network settings.


Oddly enough, it has to do with the individual devices and their initial Bluetooth setup steps. I had three different Bluetooth speakers (a Sony, a Marshall Emberton, and a Bose), as well as three different pairs of earbuds (a pair of Sonys and two pairs of craptastic knockoffs) that wouldn’t pair with my new iPhone, even though my Apple Watch and car had no problem doing so.


I was certain it just had to be the phone and not the SIX different Bluetooth items, but when the first Apple guy couldn’t figure it out, his supervisor came on, asked me the model # of each of the items I couldn’t pair, looked up the pairing instructions, &, amazingly, one by one, each one paired with my new phone when I followed his directions!


Now, I’m no tech newbie, and I had no trouble pairing any of this stuff the first time around with my iPhone 13. I also know I hadn’t followed the detailed steps he read off to me, either — even though I was reading along to a copy of the manual he’d sent me, so I know he wasn’t making this stuff up!


So try following the pairing steps of your Bluetooth device precisely from the manual, even though you’ve never had to do that before. Apparently the iPhone 16’s a prissy little thing that wouldn’t think of accepting an invitation from a Bluetooth device unless she was introduced properly through a formal courtship in the front parlor.

Ok. I have made progress on my Bluetooth iPhone 16 issue. Don’t waste your time with Apple. What I had to do is reset all my Bluetooth items …… speakers, headphones and music systems. When I say reset I mean use the reset button on my speakers and hifi. I also had to upgrade their firmware. After I had done this the items showed up in my iPhone 16 Bluetooth list.


So ….. put your headphones into Bluetooth discovery mode and it should appear on the iPhone list.


For the record the connections are robust now that I have connected them to the iPhone.


I feel very aggrieved Apple didn’t know this as it’s so basic. Also why has this happened?


I have not tried to connect my phone to my car so I am expecting fun and games when I try.

“If the real bloody VPN is the cause, could you please let me know WHY there is no problem with my iPhone 11 Pro Max? My iPhone 11 Pro Max is running VPN 24/7.”


Sure, the iPhone Pro Max is using a different modem, running different firmware and different software. Yes, the version number is the same, but software is different of when required for specific hardware. For example the 11 PM is an Intel XMM7660 BT modem. You 16 PM is using USI Global Wi-Fi & Bluetooth Module 339S01463. One modem may be affected by VPN and the other has issues.


Also beta version iOS software is a problem choice when troubleshooting a perplexing issue. The engineers on the support side don’t necessarily know what the beta engineers are doing. You’re chasing your tail. Ditch the beta software and don’t make comparisons to different devices. It’s like saying my Ford Mustang doesn’t run like my Ford Explorer from 5 years ago. Pointless.

Hi everyone,


I've been experiencing continuous Bluetooth connectivity issues with my iPhone 16 Pro Max since day one. Every time I wanted to connect to CarPlay or any Bluetooth device, I had to turn off and on my Bluetooth to get it working.

However, I think I've finally identified the cause and a solution: I was using the "Mobile Connected" application on Windows. Since disconnecting my iPhone from this app, all Bluetooth problems seem to have disappeared completely. Everything has been stable and functioning perfectly for 24 hours now, which is a record for me.


I suggest checking if you have any similar apps linking your iPhone to a Windows device and try disconnecting them. It might help resolve your Bluetooth issues as well.

Let me preface my comment by saying that I switched from a 13 pro max to a 16 pro and got this stuttering Bluetooth issue.

What fixed it for me was forgetting the phone’s name in the Bluetooth setting of my other device (a Kenwood car stereo), then changing the name of my iPhone. Paired them up and it has worked flawlessly ever since.

If you don’t know how to change your phone’s name, its Settings/General/About … then the very first line is the name, which you can customize.


Hope this helps.

Done the full reset and all the other recommendations, does not work. Only thing that I have found that works 100% of the time is to disable Wi-Fi if my phone is connected to Wi-Fi. Then turn off Bluetooth and turn it back on, then it connects without issue. But out-side of that, car, computer, headset, it just randomly stops working and will not work again until I turn off Wi-Fi and turn off/on Bluetooth.

I found the mentioned solution works: Settings-General-scroll to iPhone and choose Reset Network. The only thing is you have to go to Bluetooth, click on the info icon and choose Forget Device for every bluetooth device. And then you have to go through the process of re-pairing your devices all over again. The amount of time it is minimal compared to the amount of time of satisfaction with having working Bluetooth.

From my recent experience with the same problem, I no longer believe it's an Apple problem, but rather how Bluetooth itself works. I have several bluetooth devices my self including hearing aids, my car and some speakers. What I had to do was "forget devices" meaning I had to "unpair" them from my old iPhone, and then repair them again with my new iPhone 16 Pro. That fixed everything, and is all about how Bluetooth does its pairing controls. I hope this helps.

Resetting NETWORK doesn’t help. Problem still exists. We have 2 16Pros here and both have problems connecting to various BT devices around the home and cars. Our 12s worked perfectly and still do.

starting to think these 16’s are a POS.

I noted the BT problem (and other minor stuff) 2 months ago, let it go “they’ll fix it soon”. Clearly not. Time to start harassing the “Genius’s”. Get a replacement.

Okay my new iPhone 16 pro max was doing the same thing it had trouble connecting to bluetooth , stuttering while playing music in the car n buffering. I read online that the 16 line has an issue with the cellular n bluetooth chip. After trying everything replacing the esim 2 times , updating the network settings, n 4 calls to my carrier . They replaced the phone. No issues with the new iPhone. Hope any of this works for any of u .
