A. Wifi scanning
B. Bluetooth scanning .

3. Google >click on 3dot>usage and diagnostics >off this option

5. Long press on each app specially 3rd party and rarely used app>app info>

A. Mobile data> allow background data usage>off

@Ehsank, bro i already done all the steps you mentioned above when i raised same issue and you comment on that, even i accept your answer as solution... but very sadly i quote here that it won't work.
firstly, i used A30s, when i update my Phone to Android 10 after that really my phone runs very smoothly and it gives battery backup around 24hrs on medium saving mode and 18-20hrs for optimised setting. but after June, 2020 update my same phone with very smooth experience it gives 12 hrs battery backup at optimised setting and 14-16 hrs on medium battery saving settings..
so, my friend i don't think ki bas 20 din k ander mobile ki battery itani degrade ho sakti hai, kyuki Android 10 update 2nd june ko mila aur june security patch 20th june ko.. na hi maine koi naye heavy app download kiye us dauraan aur naahi mai heavy gamer hu...
and for your knowledge i already send error report to service center regarding this issue, they answered as usual robotic type...
so i conclude that samsung send some bugs through update to degrade the battery as well as our models too...
bcoj it happens with all the series..
