Stop the running background apps, and calibration battery once a week

scroll down notification panel and long press the power mode then click on adaptive power saving mode. this will increase your battery life. also you can open device care then click on battery and click on settings there you will find option of sleeping apps. u can add all the apps which u think is causing the draing issue

disable inbuilt apps and uninstall third apps

Visit battery optimization, check which app consuming battery most. so take action depends on that

I think if you are taking about s9+ now, the battery of it might be degrading till now first check the battery health status and proceed further.

If you want to do it via software try using power saving mode and stop apps from running in the background.
