What could have caused this battery drain.

My phone is on standy mode. I just texted a few messages since it has been fully charged. I just upgraded to os 6.0.600. I don't have any applications running on background except facebook beta 2.0 (chat offline) and of course BBM (which i didn't use since i charged my 9780). Here is the meterberry report..

A 4% drop in half an hour is quite high, but nothing to worry about especially if you've just updated your OS.

Give it a couple more charging cycles and battery pulls before monitoring again, and see if it's improved then.
