Bro, battery backup depends on users usage pattern, so it can't be same for all users..better to analyze your usage and optimize your battery according to that..
You may also change few settings: Use dark themes/wallpapers Use Night mode Restrict background data usage Put apps to sleep mode when they are not in use Turn off wifi/Bluetooth-when not required Also disable auto sync(especially of your backup mail account-gmail or Samsung) Turn off NFC when not required Auto restart your device 3 or 4 times in a week keep brightness in between 40-50%..
