Default [Q] Question about rooting my Note 3 for better battery life

I've had an AT&T Note 3 since January. The phone is great but since the update to 4.4.2 I have been experience horrendous battery life, to the point that I'm having to charge it throughout the day.

I work construction and use my phone for several hours per day, resulting in 2-3 hours of voice calls and 2-3 hours of screen time. My last Note 2 and the current Note 3 used to be able to handle my workload while being unplugged from 7AM to 10PM at night.

If I was to root my phone, could I gain back my battery life? I have never had the need for my phone to be anything other than stock but I am desperate at this point.

Thanks
