I posted this in a different thread before. I noticed it has been mentioned already. If you are experiencing horrible battery life I recommend trying it. See the testing data below for proof.
It looks like when Sprint updated the PRL from 60659 to 60660 and on they added something that the phone will scan a bunch more channels. It kills battery life to my understanding. After reverting back to 60659 and testing it for a few days, I have noticed considerably more battery life. I am using March 20th 23549 w/cookie.
