Going to keep praising this kernel, yesterday had about 17 hours, with near 4 hours screen on time, wifi on all day, and 3 hours 20 mins worth of phone calls, and around 100 sms messages sent/received. Also have Google Now on all the time. And still had about 10% left!
Fast, fluid, smooth, battery efficient, and just excellent.
Only thing I do is disabled certain apps on start up using autostarts. Even on 3G I come home with about 70% left after a days work as during working days my usage is minimum.
