How do I clean up storage in my iPhone 6s?

I recently downloaded the most recent update (iOS 11) and I keep getting notifications that I need to upgrade my storage because I've used up all the free GB that my phone offered. I don't want to pay to expand storage, and I keep deleting photos and useless apps. How else can I make more room on my phone or is there another way I can expand my storage without paying for it?

Clear iphone

I don't even have an Iphone bud.

You should be happy and singing praises.

IPhone is a very powerful phone so I don't clean up storage it.
