I've been testing the speed of my evo.
right now i've been underclocking for better battery.
i'm curious as to what you guys are setting yours to
and how it's affected the phone and how you use it
as well as the impact on battery life.
I OC to 1190 and get about 16-18 hours of juice.

setcpu settings? kernel?
i'm using CM6 with kings kernel #2.
SETCPU attached thumbs.
Running BurntDroid 1.1 with Netarchy 4.1.9.1 CFS beta
nice! thanks. i'll give it a shot and see how my evo likes it.
thanks again
conservative
I really hate how sluggish and slow the Evo gets with scaling set to conservative.

It's only noticable when you first wake the phone. After that it's smooth. I've had no other issue.
CM nightly, Snap 7.6 Turbo at 806 mhz ondemand yields decent performance.
I'm brand new to underclocking so I don't for sure of its effect on battery life yet.

hey guys.
i'm on CM6 final with the Snap v7.6 BFS kernel (no turbo).
i use SetCPU, 499-998 ondemand and 384mhz for screen off. this works fine for using the phone.
i ran quadrant like that and i got 14xx...i put it at 1.19ghz (both min and max) and on performance mode...and got 1668...so about a 200 point increase in quadrant.
however, in both an3DBench and Fps2D i got a slightly lower score while overclocked then while on ondemand mode at 200mhz less??
is setcpu really doing anything then?
Every phone responds to SetCpu differently. I look at its purpose more for improving battery life than performance. Our phones are pretty snappy to begin with. Also, Quadrant is a highly flawed application. I wouldn't rely on that to depict how well your phone is performing.

I am not sure what exactly the latter 2 tests test but here's a guess : maybe they are testing the GPU performance and SetCPU probably does not affect the GPU frequency ? I know Quadrant is a bunch of tests that also include some CPU centric tests and that might explain the higher score.
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.
Does setpcu really work? With making battery better. I have it set with profiles just not sure if its really helping or making it worse.

I dont think it is really needed with the CPU settings in CM7 now. Does the same thing for the most part im guessing?
you can do baisic clock scaling from within cm7 settings. as for profiles, if you have a custom kernel and run smartass (on tiamat) or savagedzen (on savaged-zen) governers, you shouldn't need it. those governers do basically the same thing, just smarter.
I was wondering the same thing. On sense roms with setcpu I could easily go a whole day and still have 50% battery left. With cm7 I can only go about 14 hours before its completely dead. The odd thing, I have a profile in setcpu to lower the speed to 245 (the min) below 50%. On sense, I can totally notice it slow down, and can totally notice the battery draining much slower below 50. With cm7, I don't notice any slow down and the battery will actually drop quicker below 50, much quicker than if the battery is above 50. I am using whatever kernal cm7 came with

Try using Tiamat or SavagedZen. I get great battery life on both. You would definitely benefit more from an SBC kernel, but you will still get better battery life with the non-sbc builds of those kernels as well. Which you choose is up to you. Despite a bad name, most users have no problem with SBC kernels. However, the risk is still there. I'll take my battery possibly pooping out early for the extra hours I get out of SBC.
Once you've flashed whatever kernel you want to use, set the governor to smartass (or SavagedZen, if that's what you're using).
whats the best governor when running 245/998 non overcloked? i want speed but retain good battery life with a sbc kernel. so far i have had no luck.
conservative
interactive
smartass or ondemand?
I'd say Ondemand with a screenoff profile.
I like interactive with a screen off profile

i like interactive too but it seems to drain the battery faster.
screen off 245-422 on demand
and conservative for normal use.
i get pretty good battery life.
Smartass on tiamat works great for me. I use a 128/2.. Screen off profile
Swyped via my cyanogenized and gingerbreaded EVO
I use sz on demand. Alot of the other govs seem to be real laggy or drain the crap out of my battery
Personally, use Tiamat 3.3.8, 245/537. I ramp it up just a tad if I'm playing an emulator.
Why does the Tiamat kernel not have an "On Demand" governor? What should I use for my screen off profile then?

My guess is SMARTASS is the ONDEMAND replacement?
Hi guys, I'd like to ask you a question about undervolting. I'm using Andromadus Beta 5 at the moment and it's working well enough for me, but under my rather heavy usage, my battery seems not to last that long. I'm already on the latest .19 radio and my CPU is clocked at 1GHz max with smartass v2 governor and 768 max conservative screen-off (with SetCPU).
I remember that when I was on GB (CM7.1) I used a slightly lower cpu voltage and everything was fine, so does anybody know if it's actually possible to edit the voltage table or whatever in order to UV my CPU on Andromadus?
Thanks in advance!
Don't bother, the Andromadus kernel already has somewhat low voltages. That said: https://twitter.com/rmk40/statuses/170239362020282369
Thanks for the answer. Actually the fact that undervolting the CPU doesn't bring any improvement in battery life seems a bit strange... I was hoping at least in a 5% increase. I also have to say that I have 3G and data always active, so probably that's the main reason of my short battery life.
