Samsung — Overheating and fast battery drain S20+

I have bought Samsung S20+ last year in October and since the first day I have observed overheating issue even though till date I haven't run any game in the phone. Further the battery doesn't even last a day and it drains out very quickly. If the battery level is down to 20% its just a matter of 10 minutes before it shuts down. This is the worst battery performance I have observed in any flagship phone I have used till date. If I shoot video, the phone heats up so much that it becomes difficult to hold the phone. Samsung, please look into this issue immediately as the problem is increasing day by day and battery performance is degrading every passing day.
