Any apps that are using your battery heavily can be tweaked via their preferences settings within the app, and if necessary they can be put in sleep or deep sleep mode. 

There is an optimisation option in your Samsung Device Care Section @Ivan H 

The following are generic troubleshooting steps. 

• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. Alternatively long press the power off button and then long hold on Turn Off to get to Safe Mode. 
• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

If you perform a forum search you should find existing threads with some further help within.  

If i can be of any further help please don't hesitate to ask  😎
