Traditionally, planes had to fly stepped down approaches:
Descend, hold altitude, descend further, hold, ...
Every altitude hold costs fuel as the descent has to be stopped.
Nowadays, they're changing over to continuous descent approaches, which means less throttle-jockeying and less fuel burnt.
Autolanding systems vary throttles as well to hold speed / descent rate.
