"backup size too big: I have an iPhone XS 256 GB with 15.5 iOS. Recently I tried to backup my iPhone to iCloud, but it was unsuccessful. when I tried to check the "next backup size", it comes up 16,85 TB. I already tried to force restart my iPhone, but the size still 16,85 TB. what should I do?"

Based on Personal Experience:

Try Re-Updating the iOS:

I was having this same issue, and I contacted Apple Support. They had me Re-Update the iOS, and it worked, Try it yourself, seeing if it gets the job done.

Go Here: If you can't Update or Restore your iPhone or iPod touch - Apple Support

You need a Mac or a PC. It is typically a 20 minute process. Pretty much, it is the same ordeal as reinstalling the macOS: Nothing would be deleted, it's just that item that have become lost or damages, with be relocated, or replaced, respectively, to where they should b.e

Clear Space, then Back Up:

Troubleshooting iPhone Storage:

Internal storage cannot be upgraded. It is what it is. So, the maximum internal storage capacity never increases, even if you upgraded your iCloud plan. Learn More here: What's the Difference Between Device Storage and iCloud Storage? Apple Support. 

So, what to do:

Clear Space:

Try clearing internal storage though use of the following:

What Space to Clear:

A. Clear Temporary Internet Files:

Clear your Temporary Internet Files(Cookies & Cache) of Safari:

• Cookies perform remembrance of certain site-entered data.
• Cache keeps a snapshot of the last time you visited a site.
• Go Here: Clear the History and Cookies from Safari on your iPhone, iPad, or iPod Touch - Apple Support

And...



B. Clean TV and Music Libraries:

Remove all unneeded files from your TV and Music Libraries. Full-Movies take up 2-4GB typically, and a bunch of those would take up a load of storage, ideally. So, if you have any movies that are not needed, then delete them.

And...

C. "Other" being the Culprit:

System Data (formerly called "Other"), basically contains unnecessary files such as caches that are used for system ease of use - all of which gather over time. Caches would be being used for remembrance of application use.  Use my User Tip: How to Clear "Other" in your iPhone's Storage - Use Backup - User Tip.
