Please release the new android 12 update for samsung a31. Irs been 7 days since may has started. I know it is scheduled in may but sooner the better.

So my battery with full charge will last only 17hrs 30mins what can i do to stop the degrading or to increase its life? My model is a31 i had it for a year now.
