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.

Any word from her on a fix? Ours just updated and it’s very annoying, we run a business using both phones but also have kids and we never know who’s calling which one of us.


Ask one of the kids to fix this configuration for you. Pay them to fix this. It’s not particularly difficult to fix, either.


It’ll take an hour at most, if the currently-collided folks are not too fussed about the starting point for each Apple ID.


Set up family sharing, and an Apple ID for each person.


Maybe also a business Apple ID and a personal ID.


Once the corrected configuration is established, each person can also selectively enable all of what is shut off in this current collided-data configuration, which is very useful when anyone has multiple devices associated with their personal Apple ID.

No you can't. Downgrading has never been supported. If you are waiting for Apple to figure out this out, you're likely going to be waiting for a very long time. This happened with iOS 17 released in September 2023. It's close to the end of January and Apple has released a LOT of updates since iOS 17 was released. And not one of them has changed this. Apple clearly doesn't see this an not working the way they intended it to work.

Hi everyone.


This is most annoing bug ever. I have my private IPhone and my business iPhone. I've turned off all iCloud items synch on my business phone because I have business exchange account which I use for contacts, calendars and etc. I use only my Apple ID because of thousend apps and subscriptions that I'm paying. And I really don't agree that you have to use separate ids for different devices if all of them are yours. Also I don't believe that there Is official statement from Apple regarding that. I understand very well the idea if couple is using same Apple ID and that is not ok. But in my case my wife has her own id and I need to use my id only for me but without synching both device data like recent calls. One more thing... Why we have an option in iCloud settings "Phone" which is also off in my private and business iPhones if this option is not working?! I don't understand what else than synching recent calls is this option in iCloud. I hope that Apple will finally fix this annoying bug or will release an official statement how is correct to use private and business phone by your own. >:( >:( >:(

The sync is unwanted, period. I do not understand why all of these higher level members keep defending apple like you are. The amount of business calls I get, I do not want a pile of random phone numbers on both of my phones.

I really wish my car had BT but it doesn't. I'm not "defending" Honda if accept the fact that the car was built in a certain way. I'm just acknowledging reality.


Everyone knows that there are people who don't like the way Apple IDs work. No one's saying you shouldn't have that preference. But, explaining that is not the way Apple has it set up is just stating facts.


I'm genuinely happy that you've found a workaround that makes things work the way you want. But, be aware it might stop working with any iOS update.

Is your son on iOS 17?


There has been no confirmation it is bug according to Apple since the sharing was started with iOS 17. It was released 5 months ago and has received 9 updates since then with Apple making no changes or even suggesting that they will make a change.


In any case if removing the emergency contact makes a difference, it would be welcomed here on this thread.
