So, battery life won't be good....... N4 had 2100 mAh. But its good enough to last you a day. I charge my phone to 100% in morning before leaving for class & it easily lasts till evening(i play games in it in intervals b/w classes)The only turn down for me for Nexus 5 is the battery. 2300 mAh is really low on that kinda h/w.
Maybe Google has optimised battery usage in kitkat, we won't know unless detailed review is out
