iCloud backup too big

As the title states, I’m having problems with iCloud. I believe the phone should be able to be backed up to iCloud without paying for it and recently the iPhone backup keeps ballooning. I went in and disabled 100% of the apps from being backed up and my backup size is still over 7.8 GB. Any idea why?

You can easily create an iCloud backup on iPhone by visiting the Settings app to keep your iPhone data safe. You can also be free to restore the backup to a new iPhone. While you may at least once be astonished by your iCloud backup size. Why the iPhone iCloud backup is too large?

In this guide, we’ll explain to you the common reason why iCloud backup is too large, the way to reduce iCloud backup size, and everything you may be concerned about iCloud.

Part 1. Why iPhone iCloud backup too large

If you want to figure out why iCloud backup is too large, you may need to learn about what gets backed up. When you go to the Settings app > your account > iCloud > Manage Storage > Backups > Choose your iPhone, and you will see a long list that iCloud attempts to backup.

Check iCloud Backup Size

Besides, you can also see the backup size for each item on the list. It can better explain why your iCloud Storage is full in a short time and your iCloud backup size appears to be so huge.

What takes up too much space in iCloud
You may not realize it, but it really happened that messages and photos take up too much space in iCloud.

No matter what messaging apps you are using, iCloud will backup not only the conversations, but also all photos and videos you’ve received from your friends. If you don’t want to delete all your conversations, at least you should remove some long videos and irrelevant photos, like the sandwich your friends made for lunch last week. You probably don’t have to backup things like that to your iCloud.

As for photos, since iPhone takes high-quality photos, the free space in iCloud can easily be full of them.

Part 2. How to reduce iCloud backup size

If you find iCloud has got a huge backup size, you can choose to reduce it by deleting and removing data that you no longer want from your iCloud backup, such as old iCloud Backups, Messages, and other apps that backup data on iCloud. Here are the detailed steps to reduce huge iCloud backup.

To delete old iCloud Backups, go to the Settings app > Tap [your name] > Choose iCloud > Manage Storage.

Manage iCloud Storage

You can click BACKUPS > Tap the name of the old device whose backup is unnecessary for you > Tap Delete Backup to move it from your iCloud. By tapping the name of every single app, you can also delete the app data on iCloud.
