Strength bars - computer vs. iPhone

On the computer, the strength is showing on a five-piece strength bar, on my iPhone the same strength bar is made of 4 pieces only... How are they correspond to each other? What’s the difference? Also, if I don’t practice a very old, very beginner-level lesson, will the strength of it decline? Or only if I make some mistakes that are really “beginner” mistakes?
