What is showing in your Battery and Device Care Section under Battery i.e any apps using more battery than normal.
Also if you run the optimisation tool it will tell you if there is any increased battery usage.
A good useful tool after an update is to clear the phone's System Partition Cache Files Section.
More info here > 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.
