Why does the battery of my Galaxy S3 drain like crazy?

The battery of my galaxy s3 drains like crazy!!

One thing that causes massive draining is playing Clash of clans ( after 5 min. It drains about 15 %)
But even if i dont play it , after charging at 1 am , i wake up at 9 am , and its 85% , even with airplane mode and wifi turned off
Note: i always keep bluetooth, sync , s-beam, smart stay off ...
It even charged slow (8 hours for a fill recharge) but i fixed it by making minor changes on when i charge the phone

Any help with the drain issue would be appreciated

Go to Settings>Battery and take a screenshot, we need to see what is draining the battery.Do it when the battery has like 20% left.

That isn't specific enough unfortunately. Go to the PlayStore and download GSAM Battery monitor. Go into settings of said app and turn on start on boot (i.e active monitor) charge to full and use normally..Then post screenshots of that, then 'app usage'

I'm almost sure it's a bad battery if it drains like that even when the phone is completely turned off, you should try another battery and see if it behaves the same.

Or charge it to 100%,and remove the battery. Then see what it says the charge is after several hours.
