Please no, not the Galaxy Nexus, you don't compare battery life to the worst...
The screenshot you have, 2 hours screen time, 24 hours of total use, with battery at 1%, that is not satisfactory to me, my friend. Coming from the Galaxy Nexus, I can imagine why you're completely satisfied, again, you're comparing with the worst.
My Nexus 4 can easily go with 2 hours + screen time, and 2-3 days total usage time at ease, and that's done with a smaller battery, and less efficient screen than MotoX. But then the N4 is running Android 4.4.3. The Android OS on that never gone pass 10%. Another example I really hate to bring it up, my retired iPhone 4 can sit idle for days(with sim, wifi, chat, facebook installed/enabled), and still have 95% battery left.
