I have a moto x 2014 and because I joined the soak test I did not spend much time on kitkat, since lollipop battery is awful I get roughly 1:30 to 1:40 of SOT, I have been considering downgrading to kitkat if it would greatly improve battery life because I have heard 5.1 doesn't help, please I would like to hear the opinion from the community thank you :)
