Notes about Battery Saver script

Can be used with HTC or custom kernels

It eliminates the need for SetCPU(unless you want multiple profiles)

Easily customizable if you use a text editor(scripts located in /system/etc/init.d)

It will set Max/Min CPU speed to 384MHz(128MHz or 245MHz if not a VDD kernel) in sleep mode

If SetCPU or Overclock Widget are detected, the script is ignored, so it will not affect them

Script is specially tuned for kernels that can set VDD levels(Included & Ziggy471's recent are the only ones that I'm aware that can do this), so you will get the best battery life from those kernels

If you want the best battery life and your phone can handle ultra low voltages, try the -100mV or -150mV zips in the FAQ section

v1.7

Based on build 1.72.405.3, which is a true FRG83-2.2.1 build

Using now a custom 2.6.32.17 MR3 based kernel by Ziggy471 specifically for EViO Series(Thanks Ziggy471)

Reduced undervolt to -50mV to help those PICKY phones that don't undervolt well

Created a -100mV for those phones that can handle -50mV but not the -150mV undervolt

Tweaked script to make sure script does not run if SetCPU is detected

Made scripts easier to customize, just use a text editor to change the values - Script are located in /system/etc/init.d

Added governor script, so just set whatever governor you want to 1 to enable and the rest to 0

Added Overclock Widget detection to the script

Set min CPU speed to 384 MHz for VDD kernels

Fix camera shutter sound(thx to troyboytn for the fix)

Made notification bar display TRUE network speeds(2G(1x) when used), instead of always 3G(EVDO)

Removed misc added apps to reduce ROM size

New low battery power pic & Talk icon
