Somehow, recently I bought the new Moto G, my feeling toward the wakelock between Moto G and Nexus 4 are almost having the same, but the biggest difference is, my Moto G one night drop like 2-3% with all night WiFi on, while Nexus 4 if WiFi on can drop like madness. maybe because of KitKat 4.4 still young, because JB 4.2.2 can perform better battery life than it.
