iPhone Call History Shared between Devices after iOS 17/18 Update? Fix Now!

Part 1: Why Is My Call History Showing on Another iPhone on iOS 17/18?

The simple answer to the question “Why is my call history showing on another iPhone iOS 17/18?” is that both iPhones are connected to one iCloud account.

Your iPhone is smart and won’t allow such things to happen independently until you let them. Even if you log in to the same account on the two iPhones, everything will get mirrored once you toggle the sync option.

Generally, iPhones are used to show two different call logs even after linking the iCloud account on two different iPhones. However, after iOS 17/18, Apple decided to merge the call logs of the devices connected to the iCloud account.

It’s helpful for people who don’t want two different call logs. But at the same time, it has puzzled some iPhone users who want to segregate it. This move by Apple was made to encourage people to create separate iCloud accounts and avoid using a single one on multiple devices.
