AirPods Pro 3 randomly connect/disconnect on iPhone 17 Pro

You are definitely not alone with this - the Me too count on your post shows others are experiencing the same thing, and this is a known compatibility issue between the AirPods Pro 3 firmware and iOS 26 on the iPhone 17 Pro specifically.

The fact that it happens during active audio sessions like phone calls and Spotify rather than randomly in silence is a strong clue. What is happening is that iOS 26 is occasionally switching the AirPods Pro 3 to a lower-power Bluetooth mode (SCO/eSCO for calls or a rebuffering state for streaming), and during that mode transition the connection drops instead of seamlessly switching. This is a firmware/OS layer issue.

Since you have already done the main troubleshooting steps, here are a few additional things to try that are more targeted:

For the Spotify issue specifically, go into the Spotify app settings and look for the audio quality options. Lowering the streaming quality from Very High to High or Normal can sometimes prevent the buffer underruns that trigger the disconnect. This is a temporary workaround but it helps confirm whether streaming bitrate is a factor.

For phone calls, try going to Settings > Phone > Calls on Other Devices and disable calling on all other devices. If the iPhone is simultaneously trying to manage call routing to multiple linked devices, it can interfere with the AirPods connection.

Also check Settings > Privacy & Security > Bluetooth and look through the list for any apps that may have Bluetooth access enabled but should not need it. Rogue background Bluetooth activity from apps can interfere with the AirPods session.

Apple is aware of Bluetooth audio stability issues with the AirPods Pro 3 on iOS 26 and has been patching them in point releases. Keep your iPhone and AirPods firmware current and this should improve over the next few updates.

Sorry but this is not specific to iPhone 17 Pro and there is nothing you can do to fix the issue. It is a known issue but it has been known since at least 2022 with nothing being done about it by apple. A genius at my local Apple Store said that apple were working on it but that was some time ago. I’ve had this issue for over a year since I bought my AirPod pro 3s and it happened with my old iPhone 13 and my new iPhone 17 Pro max. Other headphones don’t have this issue. Granted I’ve never had it with audio streaming but I very frequently have it with calls especially on Microsoft teams and especially while on the cellular network. I’m going to be switching back to my Jabras which worked great.

Im having similar issue with airpodspro3 and iphone 17. Airpods drop connectivity on calls cellular or app based. I have tried all the fixes available online and nothing works.

I have been waiting for apple to fix it but nothing has been done yet. I regret buying airpods pro 3.

I had experienced similar problems before with iphone11 + airpods pro. got airpods replaced but problems persisted. now with ipone17 + airpods pro3, after couple of trouble free days, old problem has come back again. tired lots of touble shooting, didn't work. I guess Apple thought its only a nuisance for which they are not bothered to fix up.

I have the same thing where it works great for a day or two and then I can’t get the connection to hold for even a couple of seconds and I have to put my AirPods away and just use the phone. It’s definitely a nuisance but it’s one that basically makes the AirPods unusable. I’d like to know why this doesn’t affect more people though or if everyone is just putting up with it.
