what's the best combo for pure battery life? everyone's been saying smartassv2 with sio but its not really giving me great battery life. what do you guys use?
oh and can you guys please state the amount of battery life you get with the combo you're using. thanks
I've been using smartassV2 in combination with SIO scheduler for general use on my T989 and my old Captivate, it has helped my phone last a day or usually longer.
I don't really look at my 'battery usage' as it varies with what I'm doing in the day, for the most part it did make a big difference compared to the defaults.
Also, if you're looking for better battery results underclocking/undervolting and have certain governors turn on during different phone usage will definitely make a huge impact with your battery results.
You can do this with many apps, but the one that has been working for me is usually between Pimp My CPU and SetCPU. Cheers!

I'm running calks rom, and i have setcpu with his profile settings, i just flashed the the newer kernel in the development section for superior battery charging and it has the "smartass" scaling as an option?
Which scaling governor works best? with battery and performance both in mind
"smartass" or "on-demand"
A lot of people say that interactive is really good. my phone doesn't like to play nice with it. I use performance with screen on, battery life isn't a huge factor for me. I set mine to the lowest possible with screen off. I have also heard a lot of good things about smartass, but I have never used it. I would play around with smartass and interactive and see which one works best for you
Swyped from my dark and cyanogenized EVO
I have mine all set to Smartass.
If you select a governer leave setcpu turned on and let your phone idle with the screen on and watch it.
You don't want you CPU maxing out when it's not in use.
I find smartass to keep it at the lowest clock (245 for me) better than any other governers.
Probably should add, i'm getting 20+ hours off a charge with pretty heavy use. but that's with profiles scaling my cpu down as my battery dies, all set to smartass.
With an evo and fresh 3.5.1, n4.3.1 kernal havs, bfs, sbc, the phone has been running very stable @ 1190 but the smartass setting doesnt seem to be playing too well w my phone after many benches w basic setcpu program "long bench" I have determined my phone runs optimal at conservative and performance. Battery isnt terrible on performance as if I stayed by a router for 60% of a full seidio 3500 would be 48-55 hours. This has been best combo for me for speed and life that I have found. no reboots or basic lockups occasionally for an extended time. Maybe its the way smartass looks for what to do by scaling when performance is all way looking for next task that would help it work. But thats my phone, my old droid reponded very dif to kernal swaps as I flashed many too. Battery life off the wifi more has netted me in the 40ish hour charge point. Regardlesd has held 2 days morning to evening routine.
I was wondering what were "optimum" SetCPU settings while running cyanogenmod 7?
Optimum for what? battery life? performance?
Of course, you could just keep it overclocked, as high as 1.8ghz I think depending on your kernel. But your battery life won't be that great.
You can also keep it at the stock 800mhz.
Most people I bet keep it around 1ghz, and have SetCPU profiles set up to lower CPU speed as battery levels get lower and lower.
I personally (not on CM7) set mine up to lower CPU a tad at 40%, even lower at 20%, and drastically lower at 10%.
I guess optimum for performance while saving battery life. I'm new to the whole overclocking and I'm not sure what profiles to set up

Well the thing is its really all personal preference when it comes down to it. Just tweak with your settings and check out your results.
I mean optimal performance with maximizing battery life would follow a few basic profiles:
Screen off: 245min/245max
When <10%: 245min/~500max (my personal preference)
And if you're trying to keep your battery pretty decent, I would recommend keeping your clock speed at 1ghz or lower maximum. Anything higher you're gonna start seeing negative battery life.
There are many other things to do to lengthen battery life that aren't SetCPU related, such as managing your radios and networks.
Im running CM7 with ADW EX launcher and a 3500 MAH battery. I want to know how I should adjust the CPU for maxium performance? Any suggestions help. Thanks!
Whatever setting you want.
Performance will run the cpu at max. Best performance, worst battery
conservative slowly ramps up the cpu, usually good performance and battery
ondemand ramps up cpu quickly and slowly moves it down. better perfromance, worse battery (than conservative)
Interactive - tries to modify cpu a little more efficiently- performance and battery unknown (there is no known concesus as far as I know)
Therefore if you want amazing performance and dont care about battery go performance, if you want to use your phone more than 6 hours, go with ondemand or interactive.
Thank you

If ADW Ex feels laggy, download VM Heap Tool and increase the dalvik heap size. That always worked better for me than increasing the cpu - at least as far as the launcher goes.
My Evo + xda Premium App = This post.
Am using AndroidRevolution HD and PopcornKernel for the maximum battery life.
I am using agressiveX governor.. its basically conservative with tweaks and hotplugging
At first I used franco's updater app to change my cpu min and max.. this app did not have a scheduler option but when i used SetCPU i chose deadline.. my batt life became a bit shorter.
I had 300+ min and 700+max. Was running smoothly and got about 6h on screen time thanks to both the rom and kernel being built for batt life and the conservative-like governer.
So basically i have 2 questions:
Which scheduler do I use to maximize battery life and Why is it when my device is off screen it runs out of batt so fast.. could it be due to hotplugging or the low cpu speed i have?

What are your battery stats like while the screen is off? If the phone is being held awake, you have an app that is constantly waking the phone up. Next charge cycle, provide a screenshot. I don't know just how much different schedulers help in terms of battery. I've hopped between noop and deadline and never really noticed a difference. Best bet would be to try each one. YMMV because my usage pattern may not match yours.
I have checked with CPUSpy and yes my device is entering deep sleep.. i wanna know if such a low voltage affects my phone sleep since i have hotplugging enabled

I am seriously tired of battery drain so I am now searching for a governor that would balance between Battery Life and Performance. I read this http://forum.xda-developers.com/showthread.php?t=1369817 but actually I was lost in that large number of governors, so Can anyone simply tell me what governor is the best ? I mainly leave WiFi On but Screen On is not usually for a large time ...

afaik and base on their details. personally, i use interactive+row on stock then smartassv2/ lulzactive+sio on custom.
SmartassV2:
The motto of this governor is a balance between performance and battery
SavagedZen:
Another smartassV2 based governor. Achieves good balance between performance & battery as compared to brazilianwax.
edit:
Q. "Ok. Enough of explanations. Tell me which governor is for performance and which one is for battery life."
A. Tough question! lulzactive and smartassV2 for a balance between performance and battery. For light weight tasks, lulzactive should be better for battery. And for heavy weight tasks, lulzactive should be better for performance also.
NOTE: It's not so easy to tame luzactive. If you don't know how exactly to do it, stay away from it or you will end up complaining about battery drain!

I use SmartAss V2 and SIO as governor and scheduler.
Like you, my wifi is permanently on, but screen is not on for long periods, and using this combo since Alpha releases of CM10 onward I have had good results, getting up to 2 days plus on CM10 EOL, and currently on LiquidSmooth 2.9 am getting well over a day from a charge.
Performance is good and LiquidSmooth ROM runs beautifully at stock CPU speeds (I currently use educk's Phenom Kernel ported by Madridii with 370Mb RAM, but have had great results with any Madridii kernel)
