I installed the .zip (Thanks kevdliu!) last night before charging/going to bed.
So far I have 7h 0m 3s on my battery (will update with screen shot) and here are the breakdowns. Battery life is at 61% (battery % mod)
Display - 61% (set between 1/3 & 2/3 all day) 1h 10m 53s
Mediaserver - 9% 24m 8s
Pandora - 9% 3h 21m 41s keep awake; 25m 26s CPU total
WIFI - 9% 7h 0m 3s
Cell Standby - 7% 7h 0m 3s
Phone Idle - 5h 49m 9s
For me this seems like an increase in battery life so far, but I guess I'll find out at the end of the day.
I will update later at bedtime with better results/compare to before the .zip
