Notes about Battery Saver script

Can be used with any kernels that have init.d support

It completely eliminates the need for an application to set CPU speeds or profiles

Easily customizable - See FAQ for instructions

During sleep, it will set Max CPU speed to 1.0GHz & Min CPU speed to 192MHz

If Android Overclock, No-Frills CPU Control, Overclock Widget, QuickClock Advanced Overclock, SetCPU or System Tuner are detected, the script is ignored, so it will not affect them

The script can also control how the second core works, it can be enabled full time, per profile or disabled completely

Preset profiles are:

1.45GHz - 100-85%

1.35GHz - 84-36%

1.24GHz - 35-0%

And just an FYI, even at 1.24GHz, the phone still operates very well & smooth but the battery saving are the real benefit

v1.2.1 - Unreleased / In testing now

Increased lockscreen unlock speed (unique to this ROM)

Disabled exchange security (unique to this ROM)
