    I have a 13-in Macbook Pro (mid-2012) running on El Capitan with 16 GB Ram. It was fully charged so I unplugged the charger and put it to sleep without closing it. I came back 2 hours later and noticed the Macbook was hot. I woke it up and get a notification that it has low battery. It was at 5%. I plugged it back in and 10 minutes later it was at 25%. Can anybody possibly tell me why it was hot and battery so low while sleeping?

    This is a -guess- ...

    The guess is that some process (I couldn't say which one, that will be for you to discover) keeps waking the sleeping computer up, over and over, continuously. As soon as the process completes, it goes to sleep, and immediately "wakes up again" and tries once more.

    Whatever it is, seems never to be resolved, so it just keeps repeating to the point that the CPU is getting over-worked and the battery is running down.

    Some checking of the logs might help.
    Or -- open it up, and check Activity Monitor.

    Are you "heavily connected" to iCloud, or to some other cloud?
    Do you by any chance use Spotify?
