Hmm. I think I'd have a hard time going down to 1500. My chapters always seem to naturally reach between 2200 and 3000 words. Average 2500.
I only read a couple chapters before dropping it because it isn't a genre I like but here is an example of a successful short-chapter novel. It seems to have 500-1000 words per chapter. https://www.webnovel.com/book/11489429005404205/Ultimate-Sex-System
