Icloud storage being used on more than 2 personal devices.

iCloud storage is assigned to the Apple ID, not the device. It is shared amongst any device you connect.

Hi daffne224,

Welcome to Apple Support. I understand you have issues with iCloud.

To answer your question, yes, all your Apple devices will get that extra space in the cloud when you purchase more on your iPhone.

If you find that is isn't showing up on your other devices, follow the steps below:

1. Sign out of your Apple ID on the affected devices.
2. Restart the affected devices (press and hold the Side button and either volume button until the power-off screen appears. Slide to power off).
3. Sign back in to your devices with your Apple ID.
4. You should see the updated storage on the other devices.

If you can't see the storage after a sign-out and restart, contact Apple Support directly.

I hope this resolved your issue? If it hasn't, feel free to reply to this thread or contact Apple Support directly.

Yours sincerely,

Note there's different kinds of "storage". Click on this link to "Learn the difference between your device and iCloud storage, ways to manage your space" and upgrading to iCloud+ if you need more --> https://support.apple.com/HT206504

Take-away:

1. Storage on a device itself is fixed and cannot be upgraded. You have to change your present device for one with more capacity.

2. iCloud storage is on Apple's main computers. It is not a like a normal storage hard drive but by using optimization settings on your device it can help free up device storage. Lesser used items and larger file versions can be stored in ICloud and you can get access while connected to the Internet. It does not turn a 64 GB storage device into a 64 (or whatever) + 50GB/200GB/2TB device but if you have a lot of things that aren't being used much, or you don't mind only having lesser quality photos on your device it can free up extra space so you can make the best of the GB you do have on the device itself.

Yes, by enabling Family Sharing, you can share storage, purchases, and more. (apple.com/family-sharing)

Your iPad may be out of space. iCloud space isn't added to the device, it remains in the cloud.

You cannot add storage to a device, it will always have the storage it had when purchased.

Can two phones be using the same storage if one is mine and one is my husbands?
