I thought I would try CPU Master Free to underclock as I don't game or do anything CPU-intensive often, and I don't really notice much change. I have it set to 800mhz max, set at boot, and it doesn't seem to have improved overall battery. Am I doing something wrong? Is it moreso a voltage thing?

There are so many different things that effect battery life. The cpu might have not been sucking down that much juice as it is. Could be your screen, brightest, an app in the background, etc that's giving you bad battery life.

What did it for me was setting the cpu idle setting in juice defender ultimate to 500mhz, with ondemand.

I guess you can use any program, but this was the setting that finally gave me all day battery life.

What ROM are you running? I read on the Calk forum that in FC24 he removed the Tegrak power saving settings because the phone likes to lock up below 800 MHz on ICS.

Speaking of which, it seems opening my camera freezes the whole phone now. I wonder if thats related...

Edit: Set it back to 1200mhz max, and the camera works fine again -_-

The release notes here for Calk's v1.3a mention that he removed the 800 MHz underclocking due to a kernel issue.

Ah. I'm running the FC22 repack, not FC24. Guess it happens on all the kernels thus far

Yes, I believe that. Calk didn't say new kernel issue... I think it is ICS in general.
