Charging Speed

Do any of you see any difference in charging Samsung M21 with or without fast charging

I see difference of only like 30 minutes to sometimes like 1 hours.

With fast charging:
0-100%: 2 / 2½ Hours

Without fast charging
0-100: 2½ / 3 Hours

It's always best to keep Fast Charging off if you plan to use your phone full day and charge overnight. It's always best to charge batteries slowly to ensure it's long life and high capacity.

for 0% to 100%
with fast charging 160 minutes
without fast charging 185 minutes

use fast charging for 30% to 40% charge
use cable charging for 100% charge

Always fast charging doesn't affect battery life, but slight reduction in battery backup may be observed.
