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.

Only apple is like this, lots of people switched years ago because of apple’s policies. A google ID is pretty simple to use, my google ID is used on both of these apple phones with ease.
I am now seeing what others are now.


And Google may well blend voicemail together across multiple Android phones in some future release, too. Hence using a second Google ID as a way to ensure you can keep your Android devices separate.

I highly doubt it, and it shows you don’t understand a google log in.


A phone number is attached to that phone, why any programmer thinks that syncing phone call logs on a totally different phone needs to give their head a shake. It’s a collection of private info that should not be monitored, and the reason I do not trust apples security any longer.

Yes you are correct, I replied to the wrong person, sorry.



yep the have good profits but alot has changed with IOS 17 and its annoyed alot of owners. This forum is not the only place this is being discussed and its a very small one at that.


Also its none of apple’s concern what people do with their IDs. It’s the unwanted gathering of info thats the problem here.

That's just not true. Apple owns the software. You just have a license to use it. Continuing to complain about it here, with only other users, gets you nothing. You know how you can solve this or live with it, or buy something else which better meets your needs.

Actually, it is. Apple is liable for information that is stored on its servers and they have a duty to protect it. It's not clear to me why you think this means that Apple is "gathering information". Apple designed iOS to work in a certain way. That means it shares information across Apple IDs. It does not mean that Apple has any additional access to the information.

You're going to find out this is a short term solution, which almost everyone has performed doesn't work long term and within hours or a day, doesn't work. Come back in a couple days and report the results, if you would.


I can tell you there's a couple in my office who share the same Apple ID. They tried this and initially it worked. But the next day, call logs and voicemail messages were back to being merged. Many in this thread tried this already, with initial success only to have it not work.

I only have one iPhone – so it doesn't affect me personally. But I am now curious about what that new "Phone" switch does. If we make the working assumption that it doesn't have anything to do with call log sharing – and that this is by design – what exactly is there left for it to control?


If you turn on the switch on two iPhones that are sharing one Apple ID, and then call one of the iPhones from a landline phone, do both iPhones ring – and do they allow you to take the call on either? (Analogous to how you can answer phone calls on a Mac, with the aid of a nearby iPhone?)


Maybe others here can think of similar experiments to find out what this mystery switch does.

THANK YOU! I’ve been doing research since iOS17 update. My boyfriend & I share the same Apple ID (2-different phone #’s) to make my life easier to resolve issues when they arise. I hoe they figure this out because it’s a pain in the rear.


I do sincerely hope your relationship is forever perfect, as should this relationship ever become even slightly rocky, at least one of you is going to be in seriously deep trouble with your data and your photos and even the basic function of your devices.

Sounds like its worth logging calls with Apple and complaining to get this resolved

You're making an assumption that Apple views this as something to be "resolved." They don't. Your devices are working as designed. While you can certainly submit feedback (the link to do so has been given repeatedly in this thread), I suspect you'll have about as much luck as if you asked for Apple to include an FM transmitter.
