Contacts disappeared from iPhone after iOS 18 update
I just updated my iPhone 15 to iOS 18, but after I restarted it, some of the contacts were missing from my iPhone. I really need my contacts back. Anyone could tell me how to retrieve the lost iPhone contacts?

That sinking feeling when you open your Contacts app and see half your list gone, especially right after a system update. You trust your iPhone to keep your information safe, but sometimes iOS updates, factory resets, or simple glitches can make contacts vanish without warning.
Fortunately, most of the time, those contacts aren't actually gone. They're just waiting to be retrieved. This guide walks you through five ways to recover lost iPhone contacts, from simple network checks to full iCloud and iTunes restores.
Before diving into solutions, it helps to know what might have caused the problem:
iOS update glitches: A new iOS version can sometimes reset certain settings or delay iCloud syncing.
iCloud Contacts turned off: Updates occasionally disable iCloud sync for Contacts without notifying you.
Accidental deletion: It's easier than you think to swipe wrong or delete a group.
Factory reset without backup: If you erased your phone and didn't have a backup, contacts can be gone.
Whatever the cause, here's how to get them back.
Try these solutions in order. The first few are quick checks; later ones involve restoring from backups.
After an iOS update, your iPhone may need time to re-download data from iCloud. This includes contacts, photos, and messages.
Sometimes the fix is simply giving iCloud enough time to catch up.
When you update iOS, the toggle for iCloud Contacts can sometimes turn off. Re-enabling it often brings your contacts back.
Step 1. Go to Settings > tap your name > iCloud.
Step 2. Tap Contacts. If it's already on, toggle it off. When prompted, choose "Keep on My iPhone."
Step 3. Wait a few seconds, then toggle Contacts back on. When asked, select "Merge."
Your iPhone will sync with iCloud and should restore any missing contacts.
If the toggle trick doesn't work, log into iCloud on a computer to see if your contacts are still there.
Step 1. On a computer, open a browser and go to iCloud.com. Sign in with your Apple ID.
Step 2. Click Contacts. If you see your missing contacts here, they're still in iCloud, just not syncing to your phone.
To manually restore:
Step 3. Click your name in the top‑right corner and select Account Settings.
Step 4. Scroll down to the Advanced section and click Restore Contacts.
Step 5. You'll see a list of previous contact states with dates. Choose one from before the contacts went missing and click Restore.
Your contacts will be restored to iCloud, and your iPhone should sync them shortly.
If you've been backing up your iPhone to a computer with iTunes, you can restore a backup that contains your lost contacts.
What to know: This method wipes your iPhone and replaces it with the backup. Any data added after that backup will be lost. Only use this if you're okay with that trade‑off.
Step 1. Open iTunes (or Finder on newer Macs) and connect your iPhone.
Step 2. Click the device icon, then go to Summary.
Step 3. Click Restore Backup. Choose the backup you want to restore (look for one from before your contacts disappeared).
Step 4. Click Restore and wait for the process to finish. Your iPhone will restart with the restored data.
Once you've recovered your contacts, the best way to avoid this panic again is to keep a copy on your computer. AOMEI FoneBackup makes it simple to back up all your contacts or just selected ones, in just a few clicks.
Step 1. Download and install AOMEI FoneBackup on your Windows PC. Connect your iPhone with a USB cable and tap "Trust This Computer" when prompted.
Step 2. Open AOMEI FoneBackup. Click Phone Backup, then choose Selective Backup and click Get Started.
Step 3. Click the Contacts icon. You'll see a preview of your contact list. Select the ones you want to back up. Click OK.
Step 4. Choose a folder on your computer to save the backup. (You can change this in Backup Storage Path.)
Step 5. Click Start Backup. A few seconds later, your contacts are safely stored on your PC.
If you prefer to export contacts as VCF or CSV files, choose Phone Transfer > iPhone to PC, then select Contacts and pick your format.
Losing contacts after an iOS update is frustrating, but it is usually fixable. Start with a simple check – iCloud sync and toggle the contacts switch. If none of that works, iCloud.com and iTunes backups also offer restore options, but they come at a cost. For maximum control and keeping a local backup on your computer, using AOMEI FoneBackup means you never have to look for your contacts again
