How to calculate iPhone back-up storage for the very first back-up
I have an iPhone 12 IOS17.3.1. I want to back it up to iCloud. My iCloud storage available is 4.9GB. I have reduced everything that could be backed-up to the minimum. However, iCloud 'tells' me I do not have enough storage.
How do I find out how much storage is required?
How do I find out what elements are causing the back-up to exceed 4.0GB
If I need iCloud+ I'd like to know beforehand how big my backups will be.
Hours spent on the web did not offer any answers about gauging the size of an initial back-up.
thanks in advance, Stephen
iPhone 12, iOS 17
