So, what exactly does Juice Defender do?

I got one of the paid versions on Amazon a while back, but I ended up uninstalling it, because I was using Google Voice to send and receive texts for free, and with Juice Defender turning off mobile data while the screen was off, I wouldn't know if I got texts until I actually woke my phone up.

But I decided to add Verizon's texting plan to my current one, so I ditched Voice, and downloaded Juice Defender again. Thing is, I'm not really noticing a difference in battery life, with it running, which is odd, because it does appear to turn off mobile data when the phone is locked, which is what I assumed was the biggest battery hog.

So, why does my battery life seem the same regardless of whether I'm using JD or not? Does it just not work as advertised? Is there some special setting I'm missing within the app, or something? I don't get it.

For me, it doesn't do squat. Actually, I take that back, it uses more battery than without it. I've gone back and forth with it several times trying to get it to work for me.

If you are the kind of person that doesn't use your phone much throughout the day it could work pretty well. But if you're the kind of person that uses your phone frequently throughout the day, checking the net or just using 3/4g, it will most likely not help you much.
