iCloud

Hi Moro1245,

Just to help again here are the steps for locating the information.

"Check your iCloud storage and Next Backup Size in iOS

1. Go to Settings > [your name].
2. Tap iCloud. The amount of iCloud storage that you've used is listed at the top. Learn more. 
3. Tap Manage Storage.
4. Tap Backups, then tap the device you're using. Next Backup Size is listed under Last Backup and Backup Size."

You can also find those steps in the article previously shared: If you can't back up to iCloud - Apple Support

You have to tap the Backups selection on the Manage iCloud Storage page. The same page (screenshot) you sent where you see the apps like WhatsApp, Health, Notes ect. The option is right above Siri.

Once the next backup size is calculated on that page, you can view details as to why you may not have enough storage currently.

From there follow the steps previously recommended to buy additional iCloud storage or backup to a computer. How to back up your iPhone, iPad, or iPod touch with iTunes on your PC

Best.

Hello Moro1245,

To help resolve this issue, let's follow the steps in this article: If you can't back up to iCloud - Apple Support

If an alert says that there's not enough iCloud storage

Check how much iCloud storage you have available, then check your Next Backup Size. Then take steps to reduce the amount of information you store in iCloud, or upgrade your iCloud+ plan. 

Check your iCloud storage and Next Backup Size in iOS or iPadOS

1. Go to Settings > [your name].

2. Tap iCloud. The amount of iCloud storage that you've used is listed at the top. Learn more. 

3. Tap Manage Storage.

3. Tap Backups, then tap the device you're using. Next Backup Size is listed under Last Backup and Backup Size. 

It may take a few minutes for your device to calculate Next Backup Size. 

If your available iCloud storage is low

1. Make more space available in iCloud by reducing the size of your backup or deleting information that you don't need. 

2. Upgrade your iCloud+ plan. 

3. If you still need help, contact Apple Support.

Best Regards.

Moro1245,

To verify, if you navigate to the Settings > [your name] > iCloud > Manage Storage menu, you don't see a Backups option listed there. Did we get that right?

If so, is your iPhone all up to date? Update your iPhone, iPad, or iPod touch - Apple Support

Take care.
