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.

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.

Thanks for replying.


few years ago I looked for a way to stop sharing call history between same Apple ID Devices, and I learned that if I turn off contacts sync on my device it will stop sharing the call log, so I did that and it was all good since iOS 13, but now it is broken.


also, I found a new Phone option in iCloud , I have no idea what does it mean, but I turned it off as well with no luck.

if users want to share call history, they can turn on iCloud contacts sync.

Hopefully this will get corrected, this Is a big pain that was NOT a problem before. But now it is after the update. How did you log you complaint with Apple? I do not want to see my call logs on my personal phone when I am using my company phone.

Why share the call history on two separate phone lines when call sync is turned off, this new update is the bug that’s causing this issue that was easily controlled in the phone settings previously for years.

Apparently, you can control what to share and what’s not between your single apple ID devices (safari, location, contacts, notes, messages, FaceTime, etc)


ironically, some people here think you can’t & should not separate what’s done under 2 different cell numbers.


that’s hilarious…


I’ll consider that when I’m going to buy new phones…

You seem to be close minded, yes there is something to correct. This problem only came about with IOS 17.

I do not own this company phone, why would I make a new ID to manage when this was not a issue before. Its in the settings, what content is shared and what calls are received.

I have not had this issue in the 10 years I have had a company Iphone, and a separate personal phone up until this last update. I do not receive shared messages on both devices, I have it shut off. Why would I want my call logs synchronized.

in your wisdom I should just log out of my profile on my company phone than., I am not making another account thats tied to my personal email. Company emails CANNOT be used to make apple ID’s. So now that you are educated on the issue, I guess next year I will not be looking to get another company Iphone if this is the new normal.

I'm not "close minded". There is nothing to correct.

It's working the way it should.


Oh, and by the way, as someone who has worked in corporate ID for over 30 years, I can say without reservation that using your personal Apple ID, or putting ANY personal data on company owned devices is a terrible, bad, horrible idea.


don't do it.


Your employer can create a managed ID for you using your corporate email account if they want. It won't cost them a dime.

You are saying it working, but I guess you don’t understand the issue because its not yours. There was nothing to correct until IOS 17.

Don't care how long you worked at something, does not mean a thing when something worked for alot of people for a long time, doesn’t mean you know what you are talking about and how other companies work, and how they can separate corporate work on a phone and personal.

I guess corporate iPhones will be a thing of the past in some companies if Apple can’t figure this out.
