If you take a look into your S7's Settings menu there's a 'Battery' selection. It will show you a basic run-down of what apps and services were actively using up battery power. You'll probably see the Android OS and the screen using up a lot of power, if you were just leaving your phone alone as is and the battery was being drained that quickly, that would be an issue to look into but if you're actively and constantly using it for 40 minutes, at some point you have to expect the battery charge to go down.
