Solution 1. Check iCloud Settings on iPhone

First, you can follow the path below to enter iCloud backup to see if you have changed iCloud settings on your iPhone. Incorrect iCloud settings will directly cause iPhone backup failed on iCloud.

  • Go to "Settings" on your iPhone.
  • Tap on your Apple ID, which is usually located at the top of the screen.

Note that if your "Back Up Now" button is grayed out, the problem may be with your network connection. You need to check the Wi-Fi connection or network restrictions on your iPhone.


Solution 2. Clear iCloud Storage

If the pop-up iCloud backup failed message says that it is because of insufficient iCloud storage space, then you can free up iCloud space by following the below tips:

Tip 1: buy more iCloud space
Free iCloud storage space is limited, once you run it out, you need to pay to get more iCloud space. You can go to the Settings app > click on your Apple ID > click on iCloud > Manage Storage > Buy More Storage.

Tip 2: Turn off the applications that do not need to backup
You can try backing up fewer apps in iCloud. Go to the Settings app > click on your Apple ID > iCloud > Manage Storage > Backups > Tap your current device > Turn off the apps you don't want to back up.

Tip 3: Delete unnecessary or old backups or files in iCloud.
Tap on Settings > iCloud > Manage Storage > Select the backup you don't need any more > Tap on "Delete Backup" option.
