I just got my Moto X last week so have only used it with KitKat. I am coming from an S4 which was running CM10.1 so this is my first device running KitKat. I have read through many of the other threads on poor battery life but I haven't experienced that except when connected to wifi. When I am connected to wifi my Android OS is always the top battery drainer and the CPU total is always some ridiculously high percentage like 50% of the time my phone has been off the charger. Are others seeing this too? I have grandfathered unlimited data so I don't have to use wifi but at the same time I also want my phone to work correctly, plus isn't battery life supposed to be better on wifi, not worse? I am willing to try a factory reset but considering I updated my phone to KitKat before installing or doing anything I can't imagine it will do much. Are others experiencing this issue of high Android OS battery drain when connected to wifi?
