Well, depends on what you mean by awake. Do you mean the display is active (lit up)? If so, then that would be actually a low drain for that.
Now if you mean just that it is turned on, the screen is dark and you aren't actively using it, then it could be one of two things.
One, one or more of you apps is running still. Even if you are not actually using them, but they are open, then they are draining the battery. If you want to leave the phone in a state that this won't happen, then you need to actually close your apps. Not deactivate or anything, just don't leave them open in the background. You actually have to close the app, or it is still running.
Two, it is a bad battery. If it is this one, then you likely need to take it back and have them give you a better battery.
Now it is possible, but less likely, that it is a phone issue. Another way to test it would be to start up your phone in "Safe Mode" and see if it drains so fast in there. If it doesn't, then it is an app or apps (or virus or malware) that is the cause. If, however, it does still happen in "Safe Mode" then it is likely the battery or the phone itself.
To get into "Safe Mode" please do the following.
1. First turn off the phone.
2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.
3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message "Safe mode: ON" or something similar.
4. If you wanted disable it, simply repeat the steps above, and you should see "Safe Mode: OFF" rather than on.
