The Samsung Galaxy A21s has a long-life battery with 5,000 mAh and 15 W quick charge. So the smartphone can be charged quickly.
But in order to use the full performance, you first have to activate "fast loading" in the Android system settings or the OneUI. We would like to explain how to do this here:
