Just charge it whenever, no special routines needed. Anyone who says otherwise hasn't been paying attention for years.
The only thing I try to avoid is leaving it on charge for hours on end unnecessarily beyond 100%, purely because of heat. It's hotter when on charge and heat is the enemy of battery health. I'm not OCD about it though, if I charge it overnight and I don't wake up or go to the loo, 8 hour charge it is
