I don't know about anyone else, but the 4.4.2 update for my Nexus 5 has destroyed my battery. With the Qualcomm battery guru app, I was getting anywhere from 1.5 - 2 days worth of battery life. After this update my battery has been killed with no remorse. I'm not sure what all has changed, but it is not a merry welcome. I had to charge my phone twice yesterday within a 10hr span. I got a Nexus to stay up to date, but holy shizz man(!) this is frick'n nuts.
1st pic is 4.4 w/ART & the battery guru app. 2nd pic is after 4.4.2 update; still using ART/battery guru.
