How Do You Fix When Your iPhone Won’t Back Up to iCloud?

So as mentioned, if your iPhone is not backing up to iCloud, there are various fixes that you can do. We have outlined these troubleshooting steps below.

Verify iCloud’s Operational Status

If your iPhone is having backup issues, check first if iCloud backup and other related services are functioning properly. You can check this by visiting Apple’s System Status page. Check for iCloud items on the page and see whether the green light is on. If any of the items are in red, that means that there is an ongoing system problem with iCloud. Then you can’t do anything but wait for the status to turn green again.

Inspect iCloud Storage Space

iCloud backup needs ample storage space to back up your iPhone. Follow the steps below to check the available storage space on your iCloud account.

1. Go to Settings on your iPhone.
2. Tap your Account name, then tap iCloud.
3. If your iCloud storage is full, tap Change Plan to get more storage.

If you don’t want to upgrade your iCloud plan, you can delete some files to free up storage. However, if you are still on the free iCloud plan with 5GB storage and your iPhone has exceeded this limit, it would be better to upgrade to a paid plan.

Ideally, your iCloud storage space should be equal to or more than the storage space on your iPhone. So if you have an iPhone with 512GB storage, it would be best to get the iCloud plan with a 2TB storage limit. That’s the next upgrade to the 200GB iCloud storage plans. 

Ensure the Power Source is Reliable

For your iPhone to back up properly to iCloud, it must be connected to a power source. If not, the backup process may pause repeatedly. It’s also important to check whether your iPhone charger is working properly. Replace damaged or not working USB cables and power adapters to avoid charging issues.

Check Wi-Fi Network Connection

For your iPhone to successfully back up to iCloud, it is of utmost importance that your device is connected to a reliable Wi-Fi connection. Speed and constant connection are two important things that you need to ensure to avoid problems when backing up your iPhone to iCloud.

Follow the steps below to check your Wi-Fi connection.

2. Tap Wi-Fi, then tap the name of Wi-Fi.
