Seamless collaboration among Apple devices is a highlight of its ecosystem. Photos, contacts, documents and other data can be easily shared between mobile phones, computers and tablets, regardless of which device the file is initially stored.
However, iCloud synchronization sometimes has unexpected pauses. This article will analyze the causes of this problem and provide corresponding solutions.

Why is iCloud synchronization unexpectedly paused?
First, we need to find out why the iCloud synchronization is paused. Although frustrating, there are many reasons for this problem:
- iCloud server downtime.
- The data is not synchronized between all devices.
- Insufficient storage space.
- The network connection is unstable.
- The same iCloud account is not used in each device.
- Low data mode causes iCloud synchronization to pause.
- The date and time settings of the device are inconsistent.
- System failure.
Let's check these reasons one by one to find the root cause of the problem.
How to solve the problem of iCloud synchronization pause
Once the reason for the iCloud synchronization pause has been determined, corresponding measures can be taken to resolve the problem. Of course, the problem is not always obvious. Follow the troubleshooting steps below to diagnose and resolve the issue.
iCloud server problem
Although it is not common, iCloud servers sometimes go down due to scheduled maintenance or Apple-side errors. You can determine if this occurs by looking at the Apple System Status page. Green means the server is running normally; yellow means there is a problem; red means the server is completely interrupted.
If the problem is here, you can't do much. You need to wait for Apple to resolve the issue, but you can monitor the situation by checking this page for updates to the server's recovery time online.
Discussions between devices
By default, your iCloud will not contain data for all applications. This makes sense, as the free iCloud account only has 5 GB of storage. To make the most of your storage space, you need to select the app you want to sync with iCloud.
To manage data synced to iCloud, check the apps that use iCloud on your iPhone. Go to Settings >Apple ID>iCloud>Click to "Show All".
If you want to check on your Mac, click the Apple icon in the menu bar > System Settings > Apple ID > "iCloud" > "Show More Apps". Then, enable or disable each application as you want.
Insufficient storage space
If you have enabled the required app but the synchronization is still paused, it may be because you have insufficient storage space. This is especially true if iCloud photo sync is paused, because photos take up a lot of space. One option is to upgrade to iCloud (for iPhone and Mac).
Obviously, the downside of iCloud is that you may end up paying a lot of fees, especially as the storage space you need continues to grow. A better option than constantly upgrading is to free up some space.
The most effective solution I found is to clean up the apps with CleanMy®Phone, etc. The app frees up storage space on your iPhone, but you can control what to keep and what to delete. Use the Organize feature to scan unwanted files in your phone, such as duplicates, blurred photos, and screenshots. You can view everything the app finds before choosing to delete anything you don't want. Once everything is deleted and free space is available, the iCloud Photo Sync Pause issue can be resolved immediately.
I have done this process recently and amazed at how much debris has accumulated – over 1 GB! After clearing these unnecessary files, I noticed an immediate improvement: the iCloud photo synchronization issue that plagued me for weeks was resolved.
If you need to free up some space on your Mac, you should check out Gemini. It works as follows: It scans your computer for duplicate photos and other content, such as folders, documents, and music. After the scan is complete, you can view the results. The best part is that you get notifications whenever it finds duplicates, so you can delete them immediately and prevent the storage from getting messy.
Network connection is unstable
If your network fails, try finding other Wi-Fi networks around. Connect to the best signal network for faster speeds. But remember that using a public network means your data is unsafe.
Unstable network connections may cause iCloud synchronization to be paused. The fastest way to check it is to use the Usage app and check the network connection data. With just a single tap, you can learn everything about your network connection and receive warnings about connection issues. A user-friendly interface prevents this task from being daunting – you can easily compare the normal performance of your network with current performance. Since it works on both macOS and iOS versions, you can check your network anywhere.
For Mac users who are truly passionate about technology, the WiFi Signal app is very convenient to monitor and enhance Wi-Fi connections. It delves into signal testing and real-time analysis so you can easily spot weak points and jump to a stronger network. Additionally, it sends you an alert notification when your speed drops, your Mac roams to another access point, or your transfer rate drops so that you can resolve any issues immediately. All in all, this app can improve your network performance and ensure your online experience is smooth.
Multiple Apple IDs
If your devices cannot communicate with each other, it may be because you use a different Apple ID on each device.
On your iPhone or iPad, go to Settings > "Apple ID" and check the email address you are using.
On your Mac, click the Apple icon in the menu bar > System Settings > Apple ID. The email displayed is your current Apple ID.
If you have multiple iClouds and want to sync files between them, don't worry: you can do this easily with AnyTrans for iOS. This app quickly transfers data between iOS devices, iTunes, and iCloud, as well as back up and moves your iPhone content to your Mac.
To synchronize data between different iCloud accounts:
- Install and open AnyTrans for iOS.
- Connect your iPhone to your Mac via a USB cable.
- Click on the Cloud tab and log in to your iCloud account.
- After logging in, click iCloud to synchronize and follow the instructions.
Android users can also sync data to iCloud: just use AnyDroid. This works exactly the same way AnyTrans for iOS works – you just use a USB cable to connect your Android phone to your Mac. Once connected, go to Android Mover and click iCloud to Android. Then, follow the instructions.
Use these tools, you can easily process your data on a variety of platforms, and solve organizational and connectivity issues no matter what device you use.
Personal Experience If you need to manage multiple devices at the same time, try AirBuddy. The app monitors all your wireless devices and allows you to quickly view their battery status. I remember one time, I was fixing some issues on my Mac using my magic mouse (I don't like the trackpad!). When I was very involved, my mouse suddenly ran out of power. Fortunately, AirBuddy gave me a warning about low battery in time so I could charge it for a while and keep working.
Low data mode problem
Low data mode is useful if you are worried about exhausting all your cellular data. However, it may affect certain features as its purpose is to reduce background data consumption. If you are experiencing iCloud synchronization issues while using cellular data, it is best to turn off low data mode, at least until the synchronization is complete.
To do this on your iPhone, go to Settings >Cellular Mobile Network>Cellular Mobile Data Options>Data Mode>Click Standard.
Date and time difference
If the date and time on your Apple device are different from your current time zone, you may experience sync pause issues. I used to set my iPhone to my actual time zone and my Mac to another time zone. I didn't realize this for months because everything looked good until one of the devices switched to daylight saving time, but the other didn't. This mismatch leads to some unexpected synchronization problems.
You can choose to automatically set the time zone. Always enable this feature unless you need to forge your time zone for some reason (no judgment).
On your iPhone, go to Settings & Gt; General & Gt; Date & Time & Gt; Automatic Settings.
On your Mac, click the Apple icon in the menu bar > System Settings > General > Date & Time > Enable Automatically Set Date & Time.
Old OS
If you fail to update the operating system on your device, you will encounter many problems, including synchronization pauses on information, photos, and other applications. It is always annoying to keep your phone or computer out of use for the time it takes to update, but it is necessary to get the device to work properly.
I have two solutions for you to choose from. One is to update before bedtime. If the update may take a while, for example, if it is a major version, this is a good choice. The second option is to update when you want to take a break.
To update iOS, go to Settings > General > Software Update. Check for available updates.
To update macOS, click the Apple icon in the menu bar > "System Settings" > "General" > "Software Update". Check again for any updates that can be installed.
System failure
If none of the above methods solve your problem, it may be a system failure. There are several ways to solve this problem. The first thing I want to do is turn off the device, wait for about a minute, and then re-open it to restart it.
To do this on your iPhone, press and hold the power button and volume button until you see "Swipe to shut down" on the screen.
To do this on your Mac, click the Apple icon in the menu bar and select "Shut down".
If this doesn't work, I usually just log out and then log back into my iCloud account. I recommend it as the next step because it means you have to remember (or reset if you are prone to forget) your iCloud password.
iCloud synchronization pause has several reasons - but the solution is simple
All in all, here are the reasons why iCloud syncs or uploads to iCloud are suspended and what you can do:
- iCloud Server Downtime: Check the Apple System Status Page and try again after the server resumes operation.
- Data not synced between devices: Enable the application you want to sync to iCloud.
- Insufficient storage: Upgrade to iCloud or use CleanMy®Phone (for iPhone) and Gemini (for Mac) to organize storage and improve device performance.
- Network causes iCloud to pause: Connect to Wi-Fi on a more stable network. Get the Usage app on your iPhone and the WiFi Signal app on your Mac to monitor and troubleshoot network failures.
- You have multiple Apple IDs: sync your cloud storage using AnyTrans for iOS (for Apple) or AnyDroid (for Android).
- Low Data Mode Issue: Turn it off temporarily.
- Date and time difference on device: Set the time zone to automatically match your location.
- You are running an older version of OS: Update the device to the latest OS.
- There is system failure: restart the device or log out and log back to iCloud.
