Bad Battery Life Moto X? Is this normal? (Screenshots included)

Hello, ever since I got this moto x 1st gen. (replacement) I've noticed the battery life is shorter than my other one. I have all the same apps, etc... The only battery tinkerer is battery saver (root) found on the play store. I have 8 hrs on the battery and its at 58 percent. Not bad, but only 30+ mins screen time! And half the time, it was airplane mode... Urgh!! Is this normal?
