Also hoping JuiceDefender works as well as others are saying. Just installed it, we will see. I';m gonna run through a full day with no charge tomorrow. I actually think it will help me a lot since my office is located in a low signal area and that seems to drain my battery a lot.
I can tell you that nothing will help if you are in a low signal area, as my office is in a hole that causes issues. No way I can have a Sprint phone here without charging it all through the day. I kept a touchstone here to charge the Pre every day, and I have to charge my Nexus as well. Of course, I am streaming music all day, so I'm draining it.
