Are you trying to back up your iPhone to iCloud but get the error message like "iPhone backup failed" or "your last backup couldn't be completed"? While there are various reasons why your iPhone won't backup to iCloud, they are often easy to overcome.

First of all, it is impossible to back up your iPhone to iCloud unless the device is connected to a Wi-Fi network and there is enough storage on iCloud to make the backup.

If you have accidentally disabled the iCloud backup, or automatically logged out of your iCloud account on your iPhone, the device will also fail to backup data to iCloud.

So, we’ll start by addressing these common issues that may interfere with the iCloud backup process and what you can do to fix them.

Part 2. Basic Solutions to Fix iPhone Won't Backup to iCloud

2.1 Enable iCloud Backup

One of the most common reasons why your iCloud backup fails is because you haven’t enabled iCloud backup on your iPhone. Fortunately, it is easy to double-check; just follow these simple steps:

  • Open the Settings app on your iPhone or iPad.
  • Tap on your name at the top and then select “iCloud”.
  • Scroll down to “iCloud Backup” and make sure that it is turned on (to green).
  • If it is disabled, tap on the toggle to turn it back on.

There is an additional benefit to purchase more iCloud storage: If you create a Family Sharing group for your Apple device, your family members can also use the storage you have without affecting the privacy of their data.

If you don't want to buy more space, you can also choose to free up the iCloud storage by backing up less data or deleting the data that already occupies much storage.

How to Free Up iCloud Storage

There are often five types of data that occupy the iCloud storage:

  • iOS application data saved in iCloud.
  • iPhone backup file.
  • Documents and files from Mac (if you have enabled iCloud backup on your macOS computers).
  • Data from Apple services (iCloud photo gallery, photo streaming, messages in iCloud, etc.)
  • Family shared data (that is, other family members who have been granted permission to use the storage).

On the iCloud Storage page, you can tap a specific app and delete its backed-up data, or delete the old iCloud backup file to make free space.

2.4 Keep Your iPhone in Charging

As we mentioned above, you need to keep your iPhone on charge to start and complete the iCloud backup process. When your iPhone is plugged into a power source, make sure the charging symbol is on. If your iPhone doesn't charge, try using a different charging cable or power source.
