Trick 2. Turn off the Low Data Mode

An iPhone will enable Low Data Mode automatically if you are connected to a mobile hotspot or metered connection. Even though you can still use the low-power mode to browse the internet and use some apps, it will still hinder background sync. Here is how to disable the low data mode.

Step 1: Go to your phone's Settings application and click on WiFi.

Step 2: Look for a small blue circle showing the 'i' icon. You'll find it next to the network your iPhone is connected to.

Step 3: Toggle off the Low Data Mode option.

Doing this should allow contacts sync to occur in the background without any issues.

Trick 3. Sign Out and Into Your iCloud on your iPhone

Sometimes, syncing problems occur due to a glitch, or the settings you do not know are enabled. Signing out of your account on your iPhone and back in again can sometimes solve the problem. You should back up your iPhone data while signing out of your iCloud in case of data loss.

To log out and into your iCloud account on your iPhone, do this;

Step 1: Navigate to "Settings" and click on the option for '[your name]' in the upper corner. Scroll down and click on "Sign Out."

Step 1: Head to "System Preferences" and tap "Apple ID." Once done, click on "Sign Out."

Step 4: Enter the passcode of your Mac and tap "OK."

You are now signed into iCloud again; after some time, check to see if the contacts apps synced.

Trick 5. Force the Mac Computer to Resync the Address Book

You can also try to prevent the Contacts application from accessing the files in the Address book folder. The Contacts app will automatically create a new Address book folder when access is denied and sync your iPhone contacts to the Mac. Here is how you can force the Mac computer to resync your Address book;

Step 1: Force quit your Contacts application.

Step 2: Copy "/Library/Application Support/" as a location address and open a new Finder window, then press the "Command," "Shift," and "G" keys at the same time. Or, tap on the word "Go" and proceed to "Go Folder" at the top."

Step 3: Paste the location address copied and click "Enter." You'll see the "AdressBook" folder, click on it and hit the enter key to name it again. Then add the word "Old ." When you open the Contacts application, it'll say "No Cards," so it can't access your Address Book folder.

Step 4: Reboot your Mac computer and open the Contacts app to create a new Address Book folder. Redownload, then sync all contacts from iCloud.

Trick 6. Check iCloud Storage

Usually, Apple provides iCloud storage of 5GB free for every Apple ID, which isn't sufficient for all your data. With time, the storage will quickly fill up as you sync some of your files, like photos leaving little storage for contacts. Here is how to check iCloud storage and remove unwanted data;

Step 1: On the iPhone, open the Settings app and click on "[your name]" at the top part of the screen to open iCloud settings.

Step 2: Click on iCloud to display the amount of space occupied. Choose the "Manage Storage" option to review the storage and remove some of the unwanted files. (Not enough iCloud storage?)

Step 1: Click on the "Settings" app to open it.

Step 2: Find the Contact settings and click on "Accounts."

Step 2: Deselect the option for "All [account]" for a third-party account such as Gmail.

Step 3: Ensure you select "All iCloud" and click "Done" to display the "Contacts" list. If you do not see it, it is stored in another account.

Trick 9. Check for Any iPhone Updates

Check for available updates and install them on your iPhone, which can help fix some undetected bugs in your system.
