I think this is only good at improving wifi network performance..
Most of the people are fine with wifi networks but still there are some range issues I think ..
The problem is mainly with mobile data network bro rather than wifi ..

But this setting is useful 👍👍

My M21 doesn't have any network problem.
Compared to other Samsung devices in my home, my M21 gets faster mobile data speed(BSNL 3G).
But my phone battery drains by 10-15 % overnight.
But when I try Flight mode, my phone battery drains 0% full night.
Can't understand why is this problem 😔
Tried factory reset too 2 weeks ago.
This problem started just after updating my device to One UI 3.0.

Yes bro I too faced same issue on my m51 after android11 update .
6-7% used to drop on that time ..
Now it is almost ok ..

May be due to any optimisation issues sent error report bro ..
Also puting flight mode is not that good in case of any emergency call incoming..
Try to put it on maximum power saving mode and try

Check if some background apps are draining your battery. If so, then optimize/hibernate/disable them.
