[Q] Battery management

[tbvnz]

I love this phone and I thought the battery was pretty decent for a smartphone. I was getting roughly 12 hours of charge on a normal work day and I'm a pretty heavy user. That was until a buddy told me about Juice Defender. I installed the free version and used the "Balanced" profile. The phone was charged fully and I went about my normal weekday. Wow! 25 hours and 18 minutes later I resorted to connecting to a charger! This is my first Android phone so I'm not very familiar with all the hacks and mods out there (I'm still trying to get my nerve up to try rooting). But, I must say I'm impressed. Are there any better battery manager apps out there, is this the best, or are they all basically the same?
