I have an oc kernel and was wondering what the safest and best setting to put CPU at on cm7. On demand, smart ass, interactive, conservative, etc. I'm looking for a good balance of speed and battery life. What is smart ass setting anyway? Thanks xda gods!

I don't know who makes OC Kernel but alot of people use Smartass on these forums. It comes with a built-in screen off profile to save battery life. Im using Tiamat4.0.2 on CM7 nightly #70 and my SetCPU profile is smartass with 128min/537max. I get NO lag whatsoever. You could just play around with the governors and min/max until you find whats smooth for your phone.

hi, I'm currently using no frills CPU to manage my CPU speed, with Virtous unity ROM, max is 1.5ghz, shall I do 1.2 ghz and leave it on demand or performance? What would use up the battery more?
also, what do the other options do apart from performance and on demand? Like interactive and conservative etc?
I currently have mine set at 1.3 (ondemand), do not choose performance it will drain the battery.

Could you explain what each governor does please, I dont know them such as interactive, conservative, etc. and which one is the most sufficient one for battery saving?

Try using search it's shouldn't be surprising that other people may have already asked this question, or if your too lazy
I did do some searching on Google and didn't come up with much specifically for the Epic.
But what I wondered is, what is the best Governor and I/O scheduler for the following conditions:
1. Performance
2. Battery Life
Well if you want performance and battery life you should OC but run it conservative, I use the sio I/O scheduler I have tried them all and like this the best.

Besides voltage control, is there an I/O scheduler apps on the market.

I think no frills CPU control works
Sent from my SPH-D700 using xda premium
To my knowledge, apps that allow changing of io schedulers, are only doing so for the sdcard.
This applies at minimum to No-frills, as I've looked at it's open source code.
You would want to use an init.d script (or similar) to set them for all partitions (or the ones you want that scheduler to run on anyways).
If anyone knows of a specific app that will change more than just the sdcard's scheduler, please let us all know.

Well I wasn't thinking I could have OC and battery life, so I figured it was more one or the other.

I'm having trouble finding a CPU app that works perfectly with this phone. I've tried setcpu, CPU master, system tuner, and nstools. What's everyone using to oc this thing?

Depends on which rom your running but in general...you should use none. Most roms already uv and oc and if u use an app it'll butt heads.

My issue is that it seems like my phone is skipping steps all over the place. I'm using cpuspy and the usage jumps between Max/min clocks. I'm kinda not digging that. Its the same with every rom i flash.

That's not an issue with your cpu app. It has to do with your governor (the thing that controls how your CPU scales). Most ROMs come with ondemand by default which pretty much does exactly that, which is jump from min to max as needed. If you want something that scales more, you should look at conservative (for better battery life) or lagfree/interactive (for better performance). Lagfree/interactive are only available on select kernels though (whereas conservative is almost universally available). Streamline definitely has them and I think synergy does too.
Also CPU apps don't butt heads with the ROM/kernel default settings, it just overrides the default settings.
Yea I figured that but this is the first phone I've had where on demand performs that way. I've had a nexus s, epic 4g, evo, and a g2 and they all scaled across the steps ondemand. Ondemand on this phone works like the min/max governor. But your right conservative scales across the steps well. Just a bit choppier. About to install nstools and mess with the threshholds and whatnot.

I was wondering what everyone uses or their min/max speeds? Ive been using the mild overclock settings with the 245/1024 setting currently, but will increasing it to say 1200mhz really hurt my battery life a lot? Will the 1200mhz speed only kick in when theres a game or something else resource intensive?
depends on your settings, try using an app like set cpu or anything that allows you to use profiles, this way you can help control battery life while still overclocking how youd like. well somewhat better control

The battery life is also rely on what governor that control the cpu.

I'm thinking of flashing elementalx kernel but I would like to know the best settings for it before I flash it

I don't know about best. That's definitely a question that will generate many different answers. These are my settings and they work well for me but they are also fairly conservative. By no means am I trying to get the highest benchmark scores. And of course the same settings will not produce the same results on every device. I should mention that I don't use sweep2wake or doubletap2wake, They will to some extent lower battery life.
Set CPU core separately = no
Cpu overclock to 1620 MHz
L2 cache and bus bandwidth = ElementalX
Auto Undervolting = 850 min
Thermal setting = run hot. Mine never gets very hot but then I don't do a ton of gaming.
GPU overclock = 450 MHz
GPU governor = ondemand
Cpu governor set to stock ondemand. With ElementalX governor I was seeing a slight stutter running quadrant.
Gboost = I am not using.
Enabled max screen off frequency.
Enabled USB fastcharge.
Disabled magnetic on/off. Tablet is naked, no cover.
Again, those are the settings that I'm using and they are admittedly conservative. Not using any apps like setcpu, kernel tuner or trickster. Don't forget to make a backup first.
Ok thanks, will give it a shot, thanks again
