Bluetooth Calls on iPhone 13 Pro Sound Poor After A Few Minutes

So I turned my series 2 watch off on March 9th after reading the latest comments here. Since then, I have not experienced the intermittent l noise I receive while using Bluetooth devices on calls.

I let my advisor know a few days ago but have not received a response yet. I’ve also received 0 updates related to the logs I recorded and submitted (again) in mid- February which is frustrating. Crazy it appears we are the ones to determine the cause after 5+ months. I miss wearing my Apple Watch.

I too was sent a replacement iPhone 13 Pro this week, and it did not fix this Bluetooth phone call bug. It is now clearly a OS/software issue related to 13 Pro.

This is extremely frustrating that a $1000+ Phone has unreliable Bluetooth capabilities. I have an open case with Apple and sent an email requesting this issue be escalated.

My case with Apple has been escalated and I am now working with a dedicated specialist. Over the last week Apple has been collecting advanced logs related to Bluetooth. Luckily, I was able to replicate the issue on Tuesday while the logging was taking place. The logs have been uploaded to Apple and apparently the logs and case has been sent to engineers to review. I’m waiting to hear back. I’ll post updates as I get them.

as you may have seen in my other posts, there is no fix for this at the moment. Resetting and replacement phones do not fix the bug.

I’ve already had one replacement phone and still the same issues. They told me Friday that they might just need to keep replacing the phone until we get a winner. Wtf. And when you replace the phone, you need to restore from iCloud and not back up so the phone is essentially starting “new”. So ridiculous

It is 100% an Apple software issue. If it was a carrier issue then other apps (FaceTime, music apps, etc. using cellular data would likely have issues. I don’t use Wi-Fi- calling, but I’m under the impression a Bluetooth phone call with Wi-Fi calling would still have this issue. It is just Phone calls through the required “Phone” App that are affected. I have AT&T and others posting on here with the issue have Verizon. Don’t see how Apple can point the finger at all carriers.

ive seen on here tons of other iPhone 13 & 13 Pro Bluetooth issues- mainly around dropped connectivity. Apple made buggy Bluetooth products in these latest releases.

Wow, all this time it was my Apple seriese 2 watch. I've had this problem since I had the iPhone X. I've purchased an Apple seriese 2 watch when I bought my iPhone X, and have bought a new iPhone every year. I now have the iPhone 13 and I have this issue with all my iPhones while connected to my car and all bluetooth devices.

My wife has used all my bluetooth audio devices and haven't had any issues. She has newer version Apple watch though.

@Apple support,

You've now witnessed many people suffering from this issue while having purchased your latest piece of technology. I bought my wife an iPhone 13 (no Pro) and same issue with earpods like Beats, AirPods and a normal USB earpiece from Plantronics. All suffering from a scrambled sound. Also after visiting the Apple store and trying the wipe-it-all-trick, no success.

@Apple - can this be looked into ASAP please. It's super annoying and very unsafe using the phone these days without a proper headset.

Kindly advice and expedite the resolution/research of the issue at hand.

Apple has been absolutely no help. Engineers have been analyzing my data for weeks now. Been through 3 specialists who stopped responding. They just keep offering me replacement phones because they have no idea how to fix it. Said we’ll just keep replacing until we get a good phone. I call at least once per week and get nothing from them. They just say they’re analyzing data.

That's the problem I have too. I've been working with a Senior advisor at Apple for 3 weeks, had the phone replaced, reset it 3 times and lost Contacts and Text threads in the process, been to Verizon and tested it with a different SIM card and phone# and had another new SIM card put in. Now Apple wants me to try turning off the Bluetooth in settings for 8 hours and see if it does it on handset or speakerphone before she escalates it to engineering. I think they are still trying to prove it's a carrier problem and not an Apple problem. I told her I disagree, that I see online lots of people are having the same issue and Apple needs to come up with a fix ASAP!

I too continue to have this problem since purchasing an iphone13 pro a little over a month ago. Apple chat support did a diagnostic test and didn’t find anything. Thought it was related to my AirPods, but it also occurs while using my Car Bluetooth and speaker system. It goes away if I swith it to speaker mode. Not sure what to do next…. Continuously happening on my work calls which is not good.

Hey there. Nope, I have not resolve this. It happens to me everyday when I'm on any Bluetooth accessory, no matter if it is an apple brand or my car, etc. It happens every time when a call is long and the only way to solve it is to switch to speaker or regular for a couple of seconds. But this happens again and again.

I think it is an iPhone 13 Pro issue. But it looks like a software thing.

I had my sixth call with Apple tonight. They are trying to blame my carrier, Verizon. I explained I’ve already gone through this with Verizon and it is not my phone. I never had any issues with previous iPhones until the 13. I actually had to reference this thread to get any further assistance because my specialist is saying engineers are not aware of this issue and blaming carrier issues and 5G. I am over this! Been dealing with multiple trips to Apple store and phone calls since October.

I updated to iOS 15.3 which is not available to the public yet to see if this issue is fixed. Until now I’m facing disconnections still. 

Im using a iPhone 12 Pro on a Porsche.

if people can return their devices, they should as I’ve been facing this issue since day one of purchasing this phone and I have no hope that Apple will resolve this anytime soon. It could very well be a hardware issue.

I have this same issue. When I am on any Bluetooth be it car or either of my AirPods it will very randomly start glitching like it's cutting in and out or sounds garbled like I'm under water. It does this for 10-30 seconds then stops. If I switch to speakerphone it stops but if I switch right back to bluetooth it's still doing it until the 30 seconds lapses. I've made several calls to Apple and talked to supervisors and we're still working on it Very frustrating

This issue is due to the compression of the Bluetooth recording. As of now iOS 15.x is recording at approx 80kbits/s.

On Android phones you can set the Bitrate you want to record ...at least in the voice memo app.

On iOS unfortunately you cannot choose.

If anyone has contact to an apple engineer..please point them at the right direction. The transmission between Bluetooth device and iPhone is the problem not the phone itself.
