iPhone SE (2016) Does an old iPhone battery charge faster?

If a battery is at 80% health, would this charge faster than a 100% health battery? obviously an old battery it's not going to last as long so i'm assuming charging is faster?

Yes. It does charge faster, just like other types of batteries being used for many years and won’t hold charge they designed for anymore.
