My old iPhone is displayed on my devices along with all the others to which my Apple ID is linked. Do you know what happens if I remove iPhone from my Apple ID?
When you remove an iPhone from your Apple ID, it is no longer associated with the Apple ID. And it will no longer appear in your Apple ID device list. Other important changes are like:
Because the device has been removed from your Apple ID, iCloud features associated with that Apple ID will no longer work on the device. You can no longer back up the device's data through iCloud or sync data to other devices through iCloud. The "Find My iPhone" feature will also be disabled. You can't remotely locate, lock, or erase the device through your Apple ID.
After changing your Apple ID, apps previously downloaded with the old ID may need to be updated or re-downloaded. This depends on the app's authorization and update policies. If you want to add the iPhone back to your Apple ID in the future, you can log in to your Apple ID again on the device. After logging in, you can re-enable iCloud features and other related services as needed.
