Fix iPhone Not Backing Up to iCloud

iCloud backup is popular with lots of iPhone users as it can be created wirelessly and even automatically, which is really suits those users who often forget or can’t be bothered to back up their iPhone regularly. However, even the best things will be flawed. Some users have encountered that somehow the iCloud backup failed on their iPhone. If that’s also the case with you, don’t worry, you can find your way out here. This article will take you to the reasons behind the iPhone not backing up to iCloud and how to solve this problem by ourselves.

Part 1. Reasons behind iPhone Not Backing Up to iCloud

When you run into a problem, analyzing the reasons behind helps to better solve the problem. Let’s look at the requirements for making an iCloud backup first. Connecting your iPhone to a Wi-Fi network is indispensable. If you let iCloud automatically back up your iPhone each day, your iPhone should be locked and connected to a power source.

Reading this, one may ask if it is necessary to seriously keep the iPhone screen locked during the entire iCloud backup process. Well, in fact, the locked iPhone screen is only required for starting an automatic iCloud backup, and once the backup’s begun, it is not necessary. So an unlocked iPhone screen generally inflicts no iCloud backup failure. The possible causes that result in iCloud backup not working are as below.

Above are the possible reasons that we can come up with. Knowing the reasons, we can use targeted solutions to address the iPhone not backing up to iCloud issue.

Part 2. Solutions to Take When iCloud Backup Failed on the iPhone

Solution#1: Connect iPhone to a Power Source

I know it sounds like crap. But do it when your iPhone battery is low enough and don’t let your iPhone go into the “Low Power Mode”. Connect your device to the USB cable and plug it into a wall power outlet, computer, or power accessory. Use the USB adapter and cable that came with your iPhone or the third-party accessory that is Apple certified. You may charge iPhone 8 or later wirelessly. Whatever the charging method is, make sure you can see the charging mark on the iPhone screen.

Solution#2: Ensure Wi-Fi Network is Strong and Stable

As we’ve been emphasizing, iCloud backup won’t succeed without a strong and stable Wi-Fi connection. First, make sure your iPhone is not too far from the Wi-Fi source; otherwise, it will give rise to a bad network connection. Second, test the strength and stability of the Wi-Fi your device is connected to. You can connect another device to your Wi-Fi network and see if the device works properly over the Wi-Fi. Or you can connect your iPhone to another Wi-Fi network and check if the backup process is going well. Once you confirm the Wi-Fi connection is OK, back up your iPhone again.

Solution#3: Keep Enough iCloud Space

Each Apple ID is automatically given only 5GB of free iCloud storage. When more iCloud storage is needed for backup, a notification will always pop up to remind you of that. Before you go further, you can go to Settings > [your name] > iCloud and check how much space is left available in iCloud. And you can also navigate to Settings > [your name] > iCloud > Manage Storage > Backups and tap on your device to find the size of your next backup. If the next backup size is way too large for your available iCloud space, free up the iCloud storage space by deleting some old backups and files, backing up your photos or other data elsewhere, or disabling the backup permission of unnecessary apps. If necessary, upgrade your iCloud storage plan. It will take some money from your pocket, but it is a useful way to keep enough space for iCloud backup.

Solution#4: Update Your iPhone to Latest iOS Version

Updating the iPhone is always a good way to remove some faults and errors in the iOS system as each iOS upgrade comes with the latest features, improvements, and bug fixes. The iPhone with iOS 12 or later can update automatically over the Wi-Fi network. If you don’t turn on the automatic upgrade feature, you can do it manually following the steps below.

Solution#7: Backup and Restore iPhone with iTunes/Finder

Since the iCloud backup failed, you can back up your iPhone to iTunes or Finder in macOS 10.15.

Restoring your iPhone is more thorough than resetting iPhone settings as it erases both the information and settings on the device. And you can often see this method in various guides for solving iPhone problems. Now, let’s look at the following steps.
