If you search the net seems like ever since over the air updates started in Feb/March 2014, many users started complaining about poor battery life. Some say its a glitch/bug, others say its a battery calibration issue, some say its an app creating drain. No one seems to know for sure. I would like to know from real Moto X users who installed all the over the air updates. How is the battery life? And I am hoping you could tell me how it is without having to apply all those tips to save battery (i.e., what is the point about a great display if I have to drop the brightness, etc). Appreciate any real user experience feedback.
