This is why I started using SR. I use the media player for playing music a lot on a day to day basis. I found that the media player makes the processor sit at 125Mhz Stock. On Ideal 500Mhz my battery didn't last as long as stock. I even changed removed the avoid freqs to 250Mhz then 125Mhz, not much difference. If SR is stable on your device (should be on KP), I find it saves a good bit of battery for my usage.
