I have been using Juice Defender on my android (Motorola Photon) for a while now but I am starting to use my data more and this one shuts down the 4g regardless if you are using it or not.
This thing is a battery monster but then again it has a duel core processor so I knew it would be, I am just trying to get a full day (12 - 14 hours) without having to charge it even if I am not using it.

I was looking on the market and found Easy Battery Saver so I am going to try it out.

Question is, What is everyone else using and what DONT you like about it? I would prefer free or at least a free version to try out.
