samsung galaxy s3 battery drains really fast

Last night I recharged my battery to 100% . Then in the morning I unplugged the charger and kept the mobile aside. After 5 minutes I checked it . It was reduced to 97%. After half an hour I checked it again. It was reduced to 83%. Please tell me what the hell is happening. Wifi , mobile data , GPS , All were turned off. I also bought new battery but it didn't make any difference. Moreover at 37% screen starts flickering and I have to recharge it fully then . I even tried factory reset and also checked my memory card . There is no corrupt file. Please help. Please.
