flashed kings unleashed blackr3 on my bad evo......not using set cpu right now. trying out juice defender. it did a good job last two days.( it might have been a combo of a new kernel and juice defender though). the app is tricky...... it kept crashing my phone I was racing to get to the app after series of reboots to undo what I did. Took like an hr. I'll have to do some more research on it. love my new Rom though been tweeking it all day.
