There is no solution. Samsung through its updates have done so that user sells the phone to buy new. Typical Apple style.
I have similar issue.
my suggestion to bring some relief is to put apps to sleep in background that you don't use often. put of wifi scan and Bluetooth scan in settings. put of location if you dont use. Hope it helps. if you find slight change do click on 3 dots and mark as solution.
