Subtle. This presupposes that I don't have a back up information. I do. That's not the point. The point is I need a carbon copy of my phone as it existed before hand. Not restoring for the backup is not an acceptable option. If I wanted a fresh new phone each and every time I upgraded and I would continue to do what I did back in the days of Windows mobile. That is buy whatever and the newest most capacious phone that existed was regardless of manufacture or operating system. I don't live like that anymore.
I have about 297 apps on my phone currently. There meticulously placed in folders and group on pages which I can quickly access when I need to use. They include date wheels, calculators, statutes and codes, medical references and other documents that I want to have immediate access to both on my iPad and my phone. Restoring the data alone takes hours. It would take days to read organize the folders. So, once again, despite your passive low-key dismissal, it is not a viable option to not restore the backup. While that may work for your average phone user it doesn't work for me, and it doesn't work for people like.
Also, for your edification, iCloud doesn't back up every thing. It only backs up PDF to let the phone know where to put the apps and data sets of information with in the apps so that you keep your same settings, voice memos, et cetera. You don't need 64 GB to backup a 64 GB phone. Also, you don't back up things that are stored already on icloud such as music of which I have 7 GB on the device. It be better if you were better informed before you started casting aspersions. Even if done subtly.
