So I have an iPhone 7 128gb and I’ve already used up like 80gb, can my iPhone 11 Pro Max 64gb be able to feed of off the remaining built in storage in the iPhone 7 if I register both of them under my 11 pro max 64?
iPhone 7, iOS 15
No, unfortunately it is not possible to share the internal memory.
If both iPhones are signed in to the same Apple ID, they can share storage space in iCloud. You can buy more space in iCloud, but this will not change the space in your iPhone. iCloud is a Backup option, and not an extension of iPhone storage space.
You can get an overview of what is taking up space on your iPhone here:
Settings → General → iPhone Storage
