Savage Zen/Tiamat kernel

On CM7 I dont have ondemand governor with the tiamat or savage. Only with stock CM7 kernel. What should I use instead?
Also does it take a while to notice improve me with these kernels?
Also those with awesome battery life on stock battery are you leaving wifi on? I get about half those times but I leave 3g on all the time.
I wish I could get through an 8 hour work day with 5hrs of screen on time on my battery.
Usually on my yoobao 3000mah I get 4.5hrs on screen time with no charging throughout the day lasts about 17hrs that way.
If I switch back to my stock battery I wouldnt be getting that would I?
CM7.1 nightly
yoobao 3000mah battery
tiamat 407 kernel. Everything under volted by 50mV but I do not think it is sticking.

i prefer the SavagedZen 2.2.1 kernel with savagedzen. but would suggest trying the smartass and interactiveX governors to see which one you and your phone prefer. some folks like the 3.06 version of Tiamat, you may want to ask folks in the tiamat thread about the diff between 4.07 and 3.06 (not positive on the version numbers).
i'd suggest running each for a couple days to see how it feels.
i use Tasker to activate my wifi when i arrive at work and at home...the rest of the time my wifi is off unless i turn it on.
the "5hrs of screen on time" may be an issue, the screen draws a lot of juice. perhaps if you verify your undervolting is sticking, used no widgets, do not use live wallpapers, set everything to sync once or twice a day you'd get further...but thats kinda no fun and i still don't think you'd get 5hrs.
i've had a light day on my phone...1.5hrs of screen on and i'm at 16hrs w/ 44% left. standard battery.
How can I verify the UV settings?
smartass is laggy
You guys should d/l System tuner. You can change your Governor with that app
Some guys swear by the SavagedZen kernel but it's reached the end of it's development life, the SavagedZen team is no longer supporting or updating the kernel and it hasn't been updated in almost 3 months. My personal experience with the kernel notwithstanding, I think that's reason enough to stick with Tiamat.
Turn brightness to 30 or 40%. Get a mugen 4500 mAh. Problem solved...your welcome.
Oh and there is ondemand in sz221. I am currently using tiamat 407 SBC conservative governor and my settings. No undervolt and working very nicely
I own a stock, gailio 2000mah, and siedio 3500. My 3500 never has a problem making a heavy day of use. I'm guessing that 4500 def wouldnt

you can use vipermod to set and verify your uv settings. there are other apps as well. but i find the script works well.
in CM7 you can set your governor and clock speed via:
menu -> settings -> Cyanogen Settings -> Performance -> CPU Settings
no 3rd party app is required. (unless you wish to use "profiles" like those available with SetCPU)
you may find interactiveX to be more responsive.
yes, SZ is not currently being developed and tiamat just released v407.
i may try the new tiamat kernel to see if it plays nice with my phone.
note: the new tiamat is based on 2.6.38.8 and SZ is based on 2.5.38.7.
thus far my EVO has shown a definite preference for SZ over Tiamat. /shrug
i always feel like i'm carrying around a pregnant EVO when i put on the 3500mh battery. LoL
My Evo also never ran tiamat well after 337 but 407 is running great
I avg five hours display on time. I have Deck's AOSP ROM and I turn off background data and sync twitter and email manually. I use Gemini App Manager to prevent apps from auto starting. I'm using a S-Z CFS kernel interactive x governor with SBC. I rely on 3g during my commute and wifi while at work and at home. I use the web, youtube and the xda app extensively. I don't think it is possible to have five hours screen on time using 3g only. Sprint's network is not that strong.

BEST GOVERNOR FOR BATTERY LIFE? (After POWERSAVE)

Well which Governor would be the best for battery life? I know powersave has long battery life but outstanding lag. Which Governor would be second to powersave? I use KTManta's kernel

Good battery life in Boeffla Kernel.

I'm using Boeffla Kernel 3.3 Beta6 and I'm looking for a good battery timing governor, yes i can sacrifice a little performance for it. 6-7 hr SOT is fine for me. Any suggestions?

No Wakelock yet battery drain

I am experiencing severe battery problems. Attached screenshots is "as good as it gets" in terms of battery life for me. That's with Greenify and Amplify doing their thing.
This is 3 hours of SOT a far cry from what you guys are getting.
910W8 on DPK1, stock ROM, with a the Beastmode r56 kernel. Underclocked and undervolted, with the interactive scheduler. I have tried just stock Kernel settings as well.
Flash to stock doesn't help. Brand new Anker battery.
Any ideas?
