iPhone call history shared between devices after iOS 17 Update

on my primary device I have iCloud -> contacts turned off, also handoff is turned off on both devices.


Before iOS 17.0, each of my 2 devices has its private call log & contacts.


After iOS 17.0 on both devices, I started to see the call history of both devices on my primary device.

I carry 2 iPhones with the same Apple id since ages, and I don’t want to get confused by which phone initiated personal or business calls.

Its unreasonable to maintain more than one Apple ID after all of this years.

I already reported a bug to Apple. And I came here to see if anyone else noticed/fixed this.


It's not a bug. If you carry two phones – one for work, and one for personal use – for "security" reasons, then it stands to follow that you should "firewall" your accounts and have two Apple ID accounts, as well.


The call history sharing might be new, but there is all sorts of other sharing linked to having the same Apple ID. Sharing that's been around for a long time. E.g., keychain passwords, photos, contacts, calendars, reminders, notes, and files on iCloud Drive.


iMessages are also linked to your Apple ID, whether you use "Messages in iCloud" or not.

It's not too smart to present works of total fiction to a Federal Judge. Especially ones that are obvious gibberish, and that the judge reads aloud in court, to show how easy it would be to see that they are gibberish!

Yes it’s my work phone and my personal phone. I have stopped the sync on my own, it is now working like I designed it to an actual separate phone, and has been for about a month now. Not sure why this horse is being beat to death. A temporary solution has been found, and it works well, and should be pinned at the top so people can see it before any more conversation is started by someone else.

I love that story!

My wife and I have separate ids for messaging and face time but share an id for everything else so we have a shared calendar and notes there is currently no way to separate the phone from the calendar and notes like there is with messaging. Apple needs to fix this ASAP.

That is highly unlikely as Apple is quite clear that they view an Apple ID as something that should not be shared. But, you can let them know your thoughts here:

Actually, you may think you own the software, but you don't. You have a license to use the software on your iPhone by virtue of buying the phone. But Apple owns the software and they don't need anyones permission to do what they choose to do with their software. And before you get angry about that, remember that I'm a user, just like you're a user and only telling you how software works. None of us own the software we use, even if we pay a license right to use it.

I know about the software, it’s no different than a Vehicle purchased and the software installed in it. I am disputing the argument that apple does not want ID’s shared. IMO thats none of their business what a person does with their ID and hows its used. I dont get texts on all devices, so the call log should be the same.

The data being shared should be in control by the user. The phone log sync is no longer in control of the user like other things are.

The purpose of a user forum is to help the user discuss whats not working for them, that discussion has helped others with this topics complaint. There is a way around it, if Apple chooses not to support the user and how the user desires to setup their phone, than users will look elsewhere to get the device that works for them.

There is no argument about that. Apple has explicitly stated that everyone should have their own Apple ID.

You are absolutely entitled to that opinion. But, that doesn't mean Apple has any obligation to change how they do things.

Nobody is arguing their point with you anymore than you with them. We are simply pointing out that your logic is flawed and seemingly inccorect. It’s not an attack. We are simply asking if this, why that. I think you know that sharing an Apple ID with someone is not even remotely close to having two devices with the same Apple ID. In fact, that is the very point of the ID.

Maybe we can just focus on technical things here instead. Like, perhaps what the phone slider is for in the cloud settings. I’d love to get your take on that.
