Has 11.4.1 fixed battery drain on 6s and other older devices?

I'm thinking if it's finally time to upgrade the OS on my 6s from 10.3.3. I like the features of iOS 11, but the battery drain was terrible so I went back to iOS 10.

Seems like it's working better for me now. The problem was so random that I can't say that with much certainty though.

I guess your situation is different: the battery life on my 6s was consistently about 2 hours less on iOS 11 than on iOS 10.

You probably might as well wait until iOS 12 at this point.

I got an answer to my question: my son upgraded his 6s to 11.4.1. He gets under 4 hours of usage, so it does not look like the battery drain problem has not been resolved.
