Solution 1: Check your iCloud Settings

It is a possibility that your iCloud Settings are the one in the way of getting your iPhone successfully backed up! Just one tiny setting might be preventing your iCloud from successfully backing up your information. To check if your iCloud Setting is the culprit, simply follow these steps:

    • Open Settings
    • Tap on your name, which is usually found at the top of the page

check icloud settings

Solution 2: Checkout Your Network and Network Settings

It may be the simplest of things that will act as the much-needed solution or check to tackle the iCloud backup failed issue. It might seem basic, but it is often overlooked by most and is often the culprit of many errors and issues encountered with the iPhone. It is the network, the Wi-Fi connection, and the Network Settings.

For the iCloud backup to be successful, you need to have a stable and fast internet connection and ensure that all the Settings allow for your device to connect seamlessly to the Internet. If this does not happen, not only will the backup not work, but it will most likely affect other apps as well, preventing you from accessing the Internet.

Before you back up, you might also want to make sure that your Internet or Wi-Fi source has no glitches, and that you have a fast Internet connection. This could make all the difference between a successful backup and a failed iCloud backup.

So how do you fix this error? You can do this by resetting the Network Settings (once you are done checking if your Wi-Fi connection is properly configured) on your iPhone by following these simple steps:

  • Tap on the Settings App
  • Proceed to select “General” option
  • Swipe down to find the “Reset” button, and select it.
  • Tap on the Reset Network Settings option
  • You will be required to enter your passcode for security reasons. Enter your code and confirm the Network Reset.

Your network connection should now be as good as new! If this still does not solve your problem, proceed to the next method.

Note: Before you forward with resetting the Network Settings, you must save your network Wi-Fi/cellular data details such as ID/password, VPN/APN Settings etc. This is important as going through this process will refresh all the information.

Solution 3: Sign Out and Sign In Back

This is an underrated fix for many problems with many devices, a simple sign out and sign in can fix whatever the problem was. To do this, simply follow this simple procedure:

  • First of all, open the Settings app on your iPhone.
  • Tap Accounts & Passwords at the bottom of the screen. You might have to scroll down to see the option.
  • Scroll to the bottom of “Accounts & Passwords” screen and tap Sign Out.
