Battery almost died from an unread text

[Cloud84]

I got a text from on of my buddies last night a little after 10pm. My battery was over 80% when I fell asleep. Woke up to my phone vibrating at 4:45 to see I had a text and only 15% battery left! What would cause this? The phone was face down so I'm sure the edge light went off, but would it stay on and drain my battery that bad?
