Do you have and how big is your "System" under Storage?

[k.alexander]

Some iPhones and/or iPads I've seen don't have a "System" entry (it's all the way at the bottom of the SETTINGS>General>iPhone Storage screen (give it time to load)). Others are anywhere from 4.x-9.xGBs.

The inconsistency is bugging me. Has anyone figured out why it shows up on some devices and not on others? And has it been confirmed that this represents the OS itself plus cache/temp files?

iPhone 7 running iOS 11 here: System shows, and is quoted at 6.81GB for me.

I’m not sure what it consists of, but I believe temp files may play a role. I came from the betas, haven’t done a clean install since ‘Nam. I have over half of my 32GB capacity remaining though, so I’m not worried (if there even is a reason to be). I do wish there was a clear and standard size documented for the OS to avoid confusion.

iPad Pro 10.5 system storage, 6.9 GB

iPhone 7 Plus system storage, 7.07 GB

My iPhone 6/16GB currently says 7.81GB of System. This number fluctuates within about 1GB from time to time, so I believe this means temp files are in play. This i6/16, was freshly wiped and then I installed iOS11GM on it, and from the start it had "System" storage showing, I forget the exact amount but I think it was close to 5GB. I then restored it with my backup coming from my iPhone 6S/64GB which was at roughly 9.6GB System before I got rid of it. That one came up through betas. Strangely though, my wife's 6S/64GB does not have System at all. That phone did no go through betas, but I have friends who did go through betas who are not showing System either. My iPad 12.9 Pro 1stGen also has System--I need to see how much it is.

31.74GB on my iPhone 7, that's about the entire chip on the base iPhone 7!

Well that's obviously an error. If you look around there was a bug going on in earlier betas where people's System would eat up most/all of their available storage space. This was supposedly fixed by about beta 6 or so. I would suggest a reinstall of the OS, try even restoring from backup--it would be easy to see if the problem comes back with a backup. I've also had really good luck with just installing iOS11 on top of the current device, through iTunes with an alt/option-Update and pointing the device to an appropriate ipsw file; this does not wipe the phone and has been known to fix some issues, at least in my experience.
