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.

if no one has figured this out, I was able to fix it on mine. Go to Icloud, under apps using ICloud, click show all, and toggle off Phone. Do this for all devices.

That won't work long term. Initially, it will. But within a day your call logs will sill be merged as MANY have tried this and thought they solved it only to learn they didn't. The ONLY way to stop this if you don't want to share call logs is to NOT share an Apple ID. Report back in a couple days and you'll be admitting it didn't work ultimately.

I spoke to a senior Apple adviser on Thursday. He told me he had checked with his engineer colleagues who told him the syncing of recent call logs and voice mails between 2 phones with the same Apple ID should stop if:

the users turn off BOTH the iCloud Phone slider AND the iCloud FaceTime slider on Both iPhones.


The adviser asked me to try doing this which I did immediately after our call. He said he would call me back this coming Monday afternoon to see if these actions work as intended.


The result:

  1. Voice mail no longer syncs. Yay.
  2. Recent calls still sync. Yuck.


Hence, there is a bug and I will provide the Apple senior adviser with any requested logs to help him give his engineer colleagues the information they will need to fix the bug.

Your call logs and voicemail may be merged, but only the number on the phone which is called should ring. If both phones are ringing at the same time, you have something set up wrong. Open the Settings app. Scan down to Phone and tap it. Make sure Calls on Other Devices is off.


Waiting for a fix which is likely never going to come will ultimately lead to frustration. The solution has been suggested many many times here. Either accept merged calls or separate your Apple ID's.

Security and your Apple ID - Apple Support


Don't share an Apple ID


Don't share an account with other people, even family members. Sharing an Apple ID means that you're giving someone else access to all of your personal content. If someone else helped you set up your Apple ID and password, change your password.


To share App Store purchases, photos, a calendar, and more, use Family Sharing, iCloud Photo Sharing, and other easy-to-use sharing features.


I can see where there might be some special cases – like needing to leave your survivors a way to take over your Apple ID in the event that you die. But this seems pretty clear. Using the same Apple ID is tied to sharing. Using separate IDs (and keeping passwords secure) is what you do if you want the opposite of sharing.

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.


Don't share AppleIDs.

We can't help with advice. We are NOT Apple. We didn't design or have anything to do with iOS or even work for Apple. If you call Apple, they are going to tell you this is how they intended it to work. There's not a thing ANYONE here can offer you. Devices which use the same Apple ID will get the call history made on every device using the same Apple ID. And that's that. You're looking for help, which is non-existent.


If I were you, I'd erase my work phone and set it up with it's own Apple ID. Boom, problem solved. Call history will NOT be shared between devices not on the same Apple ID. You've chosen to use the same Apple ID on more than one iPhone. That is your choice. But then don't complain when it's doing what Apple intended it to do, regardless of whether it did in the past.
