So I got this idea from Tory Heal on the EDT facebook, and it's working beautifully for my battery life.
On redux, I simply went into settings and checked "Use only 2G networks" and battery life has improved DRASTICALLY. How drastically? Instead of 10-15% drain per hour with Redux, I'm getting more like 3-5% per hour!
Looks like we found what the battery killer is! My phone would die before 5PM before that, and now it's 10 and I'm at 45%.
If you ever need the higher data speeds, it's as simple as re-enabling 3G.
