Whoa! 20% in 16 minutes??!!! Ouch!
Alright, first things first: Have you tried booting up in Safe Mode? Does it have the same battery drain? What about in Airplane mode with WiFi on?
OK, cell power is definitely a factor, so we have that out of the way. Next, try going into Application Manager, find Google Play Services and Clear Data from there and Uninstall Updates (don't worry, after a reboot it'll re-update itself).
I'd also try to disable Kik for a bit just to see if that's 'helping' the drain.
