sir ..please flash firmware from odin or from service center...it's happening because software holes came during update by mobile data or wifi..where accurate process is install software via smart switch or odin

Battery draining is problem for every new Samsung phone. Because of its ONE UI.
Every One UI phone has BIG Battery but still can't give single day backup.
