IOS update with storage problem?

Hello,
When I updated my IPhone 6 S plus to IOS 10, I was told that I am using 9.2 gigs of storage. I am still using that much, even though I cleared out about 10 or 12 aps, cleared out my downloaded music, and other things. How can I clear out more space, because all of my aps don't equal that much?
THanks,
Darrell
