Storage

Q. what is the difference between iCloud gigabytes and the gigabytes on the iPhone it’s self?

A. Review the following guide 👉 What's the difference between device storage and iCloud storage? - Apple Support

Q. if I completely restart my iPhone will the data such as pictures, data provider, photo’s ,and phone number (etc.) be wiped from the iCloud. Or will everything remain excluded the other apps on the phone?

A. If you meant that you reset the iPhone to factory settings, then ALL data on your iPhone will be deleted on your iPhone. If you have backup files on iCloud, then those files will remain on iCloud. Your cellular service provider informaiton, including your phone number, will not be deleted.

Q. is there is a way to delete all data with the apps that I have downloaded but not affecting my pictures, data provider, and phone number?

A. This is possible but only if you delete the app that you have downloaded, one by one, on your iPhone. If you perform a complete factory reset then ALL data will be removed except SIM (cellular service provider) information.

If you are just interested in saving your pictures AND having free storage space on your iPhone, then I recommend that you export your photos to a computer and remove them form your iPhone after. This will maintain the photos outside of your iPhone while creating free storage space on your iPhone.

• If you had turned on Messages in iCloud & iCloud Photos and you delete Photos, Videos and Messages from the iPhone then it is deleted from iCloud too, and vice-versa. At the same time, it is also deleted from all the devices that use the same Apple ID.
• And if you happen to take a backup either over iTunes or iCloud after deleting Photos, Videos & Messages all the photos and messages are deleted from the backup (iCloud/iTunes) too when you take the backup next time.
