    I have root and Overclock Widget. I have the CPU scale down to the 200 mhz range when screen off and 998 when screen on. Below is a screen shot after 21 hours off the charger at %49. This puts the phone at almost 2 days before a charge is needed.

    This is not a root thread. Please do not ask for help rooting and lets keep it on topic! :)

    I totally get that this is a noob request, but any way you can post a picture of your settings in the widget?

    Hmmm, this seems very interesting and obviously has merit. I will keep watching and learning about this CPU clocking stuff, and maybe explore it one day but for now I'm content with my battery (lasts at least a full day).

    I hadnt considered rooting until reading this, but now I am looking at rooting before the week is up. What are the disadvantages to rooting this EVO? Its my first android phone, but I had read a few things about rooting problems with 2.1, etc. Things that wouldnt work right. And other than this, what are some of the great things that will happen after rooting?

    Does this work with unrevoked or toast?

    Silly question, does it consume battery to make the cpu change speed.

    My root is toast, says so in my sig :)

    Of course it uses battery to change freq. You use battery every second your phone is on. The question is how much and really changing the frequency isn't using any more battery than idle.

    I also checked supress Notification to prevent it from notifing me that clock speed was changed when I turn on screen.

    This looks promising, will keep an eye on this.
    I'll be using it via unrevoked if I do end up using it.

    +1 - you'd think Google could have achieved this internally, no?

    This is awesome, but can the same thing be achieved with SetCPU, without a widget? The widget for this program is ugly and I don't want it there.
