How do I charge my electric car most gently?

Hey. What I was wondering. I set my Kona E so that it stops charging from 80%. However, I’m wondering what’s better for the battery now. Drive it down every time up to about 25/30% and then charge it again or charge it when it fits. You have 67% in the battery and it just fits and recharges again to 80% the next time then at 53% etc.
