iPhone 11 on iOS 13 having Bluetooth connectivity issues

William, you keep saying it is not the iPhone, contact your vendor. That's what I did. I contacted Apple, since my Airpods (all generations) are not working with the iPhone 11 Pro anymore. Poor BT connection quality, static sound, crackling. I have tried 3 other iPhone 11 Pro's so far at the Genius Bar. All have the them had the same issues with the Airpods. Switching back to my iPhone X (same software release) with the very same Airpods, works flawlessly. Everyone I know in my social circle who got the iPhone 11 Pro and using the Airpods for work, have the same issues. Very sad that this is clearly connected to either the Phone or the iOS.

Hi all,

I got the same issue on my iPhone 11 Pro. I've connected the iPhone to my Mac and opened Console.app to see logs when BT stack is crashing. here is the output :

bluetoothd STATUS 1305 (8)

bluetoothd Hardware error - Bt chip timed out while trying to transfer data to SPMI master (8)

bluetoothd FW PCIe core dumps disabled or not supported

bluetoothd FW log streaming disabled, skipping BTDebug log dump

bluetoothd Bluetooth error - restarting { build: release, reason: 652, context: }

I'm wondering if all people got the same error (filter message using "Hardware error" keywords ?

Couple things. I have a brand new Tacoma same issue. Make sure to update iOS if you haven’t. Then re pair the phone to the Toyota again. With the .2 update it has helped me but I still went to the Apple store and they mentioned the .3 update really addresses this. Not sure how accurate it is but hope that helps.

A lot of people on this thread have been contacted by "Apple Bluetooth Engineering" so clearly the Apple Support people are aware of this problems. In my case my issues have been fixed in iOS 13.2. I am now running 13.2.2 and have not seen any disconnections, pairing or drop call issues. But many people continue to experience problems.

This is pure speculation but the amount of issues reported and the different scenarios point to a whole Bluetooth stack rewrite/replacement in iOS 13. A strong clue is that lots of people commented they had the issues on iOS 13 even on devices prior to the iPhone 11/11 Pro so that points to software issue not hardware issue. Most likely the previous Bluetooth stack in iOS 12 was riddled with hacks and special scenarios handling which may have prevented dodgy software from bluetooth devices from causing trouble. Let's be honest who is more likely to adhere to the Bluetooth standards Apple or car manufactures who are so bad at writing software that they had to let iOS and Android into their ecosystem? Still for the user if it was working fine before it should keep working fine now so Apple will have to fix whatever they broke...

As I already commented before, I got rid of bt problems with my Sony headphones after I force booted the iPhone: vol up, vol down, press power button until phone boots. Or was it vol down, vol up, press power button... Anyways, after that I have had at least three successful calls with the headset. Before that, call transferred to and from the headset and phone constantly.

Just chiming in to say I had this issue too with my first iPhone 11 Pro 64gb. When on wifi and listening to music on my airpods, the phone would disconnect and reconnect bluetooth at random. The problem seemed to intensify if I was using the phone (browsing a web page or whatever) and always manifested itself as the bluetooth pane in Settings getting the status "unavailable" and then 3 seconds later appearing as "on" again. This happened on all bluetooth audio peripherals I tested.

Spent an excruciating time with Apple Support, who were absolutely useless in this matter, which was very surprising, given that I've had good experiences with their support before.

Then after exhausting all troubleshooting steps, having reset all settings on the phone several times, it was on to my phone carrier (where I purchased the phone) to get a replacement phone.

This turned out to be a huge pain, as of course the phone was sold out everywhere and the support team at my carrier was absolutely useless as well.

Ended up just returning the phone and buying a new iPhone 11 Pro 64gb from another carrier, thus swapping it that way around. Have had this new one for about a month now and have had no issues with the bluetooth at all, with the same bluetooth audio peripherals used with my first one.

So, in my case this definitely was due to faulty hardware (I had this confirmed with my old carrier as well, who had the phone analysed).

Shocked (or am I?) if the reason so many people are experiencing this issue, with this phone, is due to a lack in quality control within Apple.

Yes! I agree with this! I had to reset my phone as new after each update. Everything works now. I haven’t had to reset it as new after 13.2.1 (I believe). It’s very annoying but worked for me! My main issues were Bluetooth in my Tundra and this made everything work. Also, I’m not sure if any of you Toyota owners use the “Scout Navigation” app...but this was a problem for me. Everything was fine, but as soon as I finally re-set it back up, I had issues. So I deleted the app and everything worked perfectly again.

Good luck!

I only have Apple headsets, both AirPods and Powerbeats pro (that I purchased because I thought my AirPods were broken since they dropped the connection) but both drops the connection. So it has nothing to do with Apple products or not. Or cars or not.

i updated to 13.2.3 yesterday and so far (knock on wood) I haven’t lost the connection.

Knock on wood but my Bluetooth is working. I had to rename my new phone because it was the same name as my old phone and then set up as new with my car and sync and it works. My AirPod pros connect when they’re in my ears and disconnect automatically as soon as I remove them🤷‍♀️

Resolve Wi-Fi and Bluetooth issues caused by wireless interference

Wireless interference can cause Wi-Fi and Bluetooth devices to disconnect or perform poorly, but you can take steps to reduce or overcome it.

Symptoms of wireless interference

Any of these symptoms could be caused by interference affecting the Wi-Fi or Bluetooth signal:

• Device doesn't connect or stay connected
• Connection is slow and signal strength  is low
• Bluetooth audio skips, stutters, cuts off, or has static or buzzing
• Pointer movement is erratic or jumpy

How to reduce wireless interference

These general steps can help achieve a cleaner, stronger wireless signal:

• Bring your Wi-Fi device closer to your Wi-Fi router. Bring the Bluetooth devices that are connecting to each other closer together. 
• Avoid using your wireless devices near common sources of interference, such as power cables, microwave ovens, fluorescent lights, wireless video cameras, and cordless phones.
• Reduce the number of active devices that use the same wireless frequency band. Both Bluetooth and Wi-Fi devices use the 2.4 GHz band, but many Wi-Fi devices can use the 5 GHz band instead. If your Wi-Fi router supports both bands, it might help to connect more of your Wi-Fi devices to the 5GHz band. Some dual-band routers manage this for you automatically.
• Configure your Wi-Fi router to use a different Wi-Fi channel, or have it scan for the channel with the least interference. Most routers perform this scan automatically on startup or when reset.

If you're using USB 3 or Thunderbolt 3 devices with your computer, you can limit their potential to interfere with nearby wireless devices:

• Use a high-quality, shielded USB or Thunderbolt 3 cable with each device.
• Move your USB 3 or Thunderbolt 3 devices—including any USB hubs—farther away from your wireless devices.
• Avoid placing USB 3 or Thunderbolt 3 devices on top of your Mac Pro, Mac notebook, or Mac mini. 
• Turn off any USB 3 devices that aren't in use.

Avoid physical obstructions in the path of your wireless signal. For example, a metal surface between your Bluetooth mouse and computer could cause the mouse to perform poorly, and a metal-reinforced concrete floor between your Wi-Fi router and Wi-Fi device could cause poor Wi-Fi performance.

• Low interference potential: wood, glass, and many synthetic materials
• Medium interference potential: water, bricks, marble
• High interference potential: plaster, concrete, bulletproof glass
• Very high interference potential: metal

Same here. It's getting ridiculous at this point smh. I tried turning off the 'Sync contacts' button for the Bluetooth device according to this online guide and that for some reason managed to fix the Bluetooth issues for me. This has reduced the amount of the Bluetooth connectivity issues rather than completely fixing it.

Although I really do believe this is a software-issue from Apple's end. Hope this does get the awareness it needs and hopefully a worthwhile fix is released soon!

For those having issues, it would be great if you could include the device/vehicle info etc that is having the problems. Maybe this will assist apple to some degree.

I have an update on my own issue with the iphone 11 (nonpro) 2017 Hyundai Veloster. Phone would connect, but then my wife had to keep manually connecting every time she jumped into the car. Turns out, that not only do you have to pair the phone, but you have to go into settings (on the Veloster) Bluetooth settings, and enable default pairing, and contact download. They are off by default. Now the phone connects without issue when she turns off the car. These settings went back to default after we deleted her old Samsung phone. I have a happy wife.. This is good.. ;) I can confirm that the 11 pro, and non pro 11, both work without issue in this car.

Our 2019 Jeep works fine with the pro, both for Carplay, and bluetooth. The nonpro works fine for Carplay, but we have some issue with connectivity when only on bluetooth. I need to spend more time messing with this.

I did not do the 'Forget Device' or anything else although that was to be my next step. I'd suggest forgetting all devices AND resetting the network settings.

When I was researching this I saw something that said that turning off the U1 chip could effect bluetooth and wifi performance. I wonder if the U1 chip handles bluetooth and wifi and, when the U1 chip is disabled, perhaps those radios revert to an older chip that's still in the phone. I'm no engineer so I'm just guessing.

I had to remove my iwatch from my iphone, remove my iphone from my car completely. Then re-input my iwatch and re connect my iphone. I hope that helps. If not call 2nd level Apple tech. They found the fix for me.
