    So I have been playing around with different kernels and settings and logging them in System Panel. I will explain details below each pic. Usage was the similar each day with a little bit of tethering, alot of web surfing, imobsters texting and email with kids playing some games here and there as well. Running Fresh 3.2 with different kernels on different days.

    Thursday-Fresh 3.2, Fresh kernel, SetCPU ondemand, screen off profile set.
    Friday-Fresh 3.2, Kings #9 kernel uninstalled SetCPU
    Saturday-Fresh 3.2, Kings #9 kernel, SetCPU conservative, screen off profile set

    Monday night I installed Fresh 3.2 and ran the Fresh kernel with SetCPU ondemand and screen off profile and ran it the same way through Thursday.
    Late Thursday evening I installed Kings #9 bfs kernel and uninstalled SetCPU and ran it all day Friday
    Late Friday I reinstalled SetCPU and set it to conservative and ran it that way all day Saturday.

    As you can see, Tues, Wed, and Thurs were all very consistent. Tues I got appx 15-16 hours, Wed I got 14-15 hours and Thurs appx 12-13 hours. Friday was by far the best just letting the kernel do its thing with no SetCPU. Saturday sucked! Battery was dead by 6 pm with appx 9 hours use.

    I just flashed the Fresh stock kernel back on and uninstalled SetCPU and will see how that compares tomorrow. Sure would like to see the 1.5 days flipz is getting! I have read several places now that SetCPU may be counter productive since the newer kernels are managing things better lately. Does anybody know if the Fresh 3.2 stock kernel is using HAVS?

    Nice!! What program are you using to chart that? Also, I hear that SetCPU is a life saver and then that SetCPU does nothing... I dont know for sure and would like to run test similiar to yours and find out for myself...
    EDIT: Nevermind, now I see it says System Panel...

    Nice results.No,the stock Kernel on Fresh 3.2does not implements HAVS,is a stock HTC unrealesed Kernel .34 if I'm not mistaken but it supposed to have some nice tweak to improve battery life and overall performance.

    You are right, the program is called System Panel. The lite version is free but doesn't do logging. The paid version is only a couple of bucks and has been well worth it. As far as SetCPU is concerned, I think I am done with it. My tests so far indicate the stock Fresh 3.2 kernel that comes with the ROM and Kings #9 both do better alone than with SetCPU. I am running the stock Fresh 3.2 kernel today and it is tracking to end as a toss up between it and Kings 9 as the best battery life. The nod may go to Kings just for the fps cap being lifted if the battery life is comparable.

    Have you tried using SetCPU without any profiles? SetCPU will save you battery life if you change the governor on the main page to conservative from ondemand. You could also use this page to set the overclock, just avoid using any profiles.
