For those of you on CM7 (preferably RC2 or later nightlies), are you using SetCPU or the built in CMSettings CPU manager? Which is giving you better performance/battery life?
I can't help but think that the built in CM Settings CPU tuner is going to be conflicting with my SetCPU profiles.
Been using nightlies since #30 or so, and I currently run SetCPU with a normal profile, a screen off profile, and a profile for <10% battery and haven't touched CMSettings' CPU manager.
I'm contemplating just uninstalling SetCPU for a day or two and seeing what a 1017max / 245min Ondemand or Powersave governor via CMSettings ends up doing to my battery life considering there will be no screen off profile.
Any thoughts?
I dumped setCPU after a lot of testing (and even bought it on market)
I'm finding I'm much happier using inbuilt CPU settings. I think battery life is the same but performance is better due to the fact that SetCPU would sometimes get stuck in my screen-off profile when turned on causing the phone to be really slow.
I recomend uninstalling setCPU, set your ONDEMAND governor with ~1Ghz and run it... You'll find your battery about the same but much less hassle.
I have yet to try that, I somewhat feel obligated to use SetCPU since I purchased it lol. But it probably won't be the last time I waste money at the market.
Neither. CPU tuner works best for me.

its the same thing :facepalm:
Try the inbuilt one... I think its way easier
I've been wondering about this too. I don't quite understand how it works. Can I just set the frequency higher till a certain point without changing the voltage and get the same battery life?
What's the best way of doing this? Just change the clock speed or do I need to change something else or update the kernel?
Whatever you tell SetCPU to do, you'll see the same settings mirrored in the CM settings.
I say setCPU cuz as battery gets lower... I have my CPU speed lower also. Basically, 15% battery lasts me forever :] lol

Definitely. This is the one thing I like about SetCPU is having the 10% and 5% profiles so that I can get the last few % to last forever if I need it. Although in normal day-to-day use I'm never pushing it below 20%.

Yea I see this, as far as the governor changing etc.. This is why I'm wondering if it would be easier on my phone to just run only the CM Settings one.
I notice that every 5th or so time I unlock the phone, there is an obvious lag switching from the screen off profile, and my unlock sliders jitter around and it takes 4-5 tries to unlock the phone. I think this is probably partially due to both settings switching over trying to change.
I think I might try backing up and uninstalling SetCPU for tomorrow to see how it goes.

I've read on here that overclocking the Vision's CPU up to 1 GHz requires no over-volting, and in theory should not affect battery life (but not sure exactly where that information originates from). But there has been lots of debate on these forums on whether the SetCPU app helps or hurts battery life depending on screen-off profiles (underclocking to save battery) or its constant polling of the CPU clock (possibly killing the battery faster).
A kernel that supports overclocking is already part of the CM ROM. If you are on CM, you can just adjust the clock speed under Settings>CM Settings>Performance>CPU settings. Or set the CPU clock using an app like SetCPU. Choosing one method over the other is what is being asked/debated here. If you are on the stock ROM, you need to be rooted, flash a custom kernel that supports overclocking, then install an app such as SetCPU or CPU Tuner to set the CPU clock to your liking.

I'm not sure about CM's kernel with the over-volting but I do know that Pershoots kernel can be overclocked to 979mhz without over-volting (Pershoot told me himself).
At 1.8Ghz, I find the temp settings in SetCPU very useful.

Well obviously.... But why the hell would you ever need to be running at 1.8ghz? The fact that you are always using a temp-specific profile method should show you that consistent 1.8ghz isn't good for the phone...
Okay so I uninstalled SetCPU last night and I'm going to run just the CM Settings CPU manager all day to see how it goes. Running like this:
ONDEMAND governor
Min CPU: 245 mhz
Max CPU: 1017 mhz
On nightly #19 also.
Okay so its midnight almost, and I'm at 13hrs unplugged and 52% battery still. Pretty general/light use, phone is just as snappy and the lack of a screen off profile doesn't seem to effect battery at all. Liking it so far! very interesting to see the screen off profile not mattering much.
SetCPU for me. I like to have a temperature and charging profile, to prevent the phone from overheating. Even at 1ghz the possibility exists, nice to have a backup incase.
I'm thinking set cpu conflicting with the cm built in caused my ****ty running problems. I have not used setcpu since and been good so far

With multiple tries... If you change the settings on one, it cancels the settings on the other... Maybe it's because you had set on boot enabled on both?
im going to run the CM tuner and uninstall Setcpu and see how it runs. i never thought about this but i do get that lag when i turn my screen on sometimes. im gonna miss having the profiles but ill see how it runs over the coarse of a couple days.
Hey everyone, just wanted to post this to see what cpu speed works best for you guys.. Im using these preset things with the program like performance or power saver etc but i dont seem to notice a difference all of them seem to be the exact same.. Wondering how to make it good for like 50% power and 50% performance, basicly balancing the 2 out as long as its better than stalk and not burning out my cpu.. so thanks, let me know what works for you guys as ive heard its slightly different for everyone else
(HTC EVO 4G)
I use the standard "ondemand" governor with a 998max-245min, but the thing I found makes the most difference are the settings under "Advanced".
I use the below "Advanced" settings along with a 245-245 screen off profile.
Seems to get me the best battery and cpu scaling.
It also helps to use an undervolting kernel like Freedom-More.
Try that for a couple days.
NOTE: click the apply button a couple of times (might be bug but they sometimes don't take on 1 button click). Try them as is without "Set on Boot", until you are sure that your phone likes them. Plus, check after a reboot that you verify/reapply them.
Sampling rate: 20000
Up Threshold: 85
Ignore nice load: 0
Powersave Bias: 14

The "presets" are how the cpu scales i'd use "interactive" or "smartassv2" 245 min and max at 998+ then search around for here for various profile set-ups
I'm running the Gingerbread-Evo-Deck 1.3 with a Savaged Zen 2.2.1 CFS HAVS Kernel. I'm also undervolted 50mV, and using the interactive x governor set at 128MHz-768mhz. Running a few other simple tweaks learned from Carhauler, and I've got excellent battery life and great performance.
I currently run mine on an ICS rom & it comes standard with a tiatmat 4.1.0+ kernel & the cpu is running at about 245mhz-1036mhz with smartass governor(I usually set it to smartass v2 but it switches back to smartass haha). My battery life for me is enough to get me thru the day.

Which ICS rom are you running?
I currently running RCMix3d Runny® Sense 3.5. Should I just got with ICS to overclock or just find a kernel that allows it?

Get a new kernal. Try Tiamat 4.1
I have my SetCPU at 128min 1152max smartassV2(i CAN overclock up to 1267) with 1 profile:
Screen Off 128min 245max
My battery life is extremely good.

Default settings are fine for a decent battery life. UV doesn't really increase the battery life; its used to reduce the heating when using processor intensive apps (games). But if you don't know what you are doing, its recommended that you don't change any settings.

Is it pretty much the consensus that undervolting w franco kernel on the N4 doesn't noticeably increase battery life?

I haven't notice any significant increase in battery life, if any. However, the device runs so much cooler than before.
I am now experimenting with 150mV UV. Haven't had any problems with stability or camera.

Undervolting can somewhat increase battery life. Undervolting is meant for lowering CPU power to reduce thermal heat and it will definitely increase the life of the CPU. It doesn't really increase battery life, it might save a little bit but not much.

Got a question for Franco kernel + Franco Kernel updater app user
Do you have the hotplug control in Frequencies/Voltages menu? It seems to be not there for me. If I flash it with stock kernel then the hotplug control is there but can't change anything. If I flash it with Franco's kernel, then the hotplug control is missing.

Franco didn't add hotplugging feature back yet. He might add it back in the next app update.

Something similar happened to me while I was using faux. You have to flash the rom first and kernel later. If you flash kernel first and then the rom some of the features on kernel settings might disappear.
Hotplug is available since quite long time.
Nothing to do with flashing Roms.

thought I'd bump instead of starting a new thread.
what's the best settings for the cpu hotplug control? I've set suspend frequency to 384000, suspend frequency is the CPU frequency when the screen if off?
cores on touch is how many CPU cores get used when screen is touched? I kept this to 2.
now I'm not too sure what first_level is used for though. so I left it at 60.
the new app is good but lacks description for some of the settings.

Do u want to apply the 'best settings' to increase battery life or performance? And I'm using the ones you have stated, pretty balanced stuff. Keep it that way
Hey guys.
I have a clean Mahdi ROM (the latest from like 1 week ago) and have the feeling that the battery drains slightly faster than in stock. Apart from other things I started trying different kernel tweaks and I discovered the following:
The governor, although showing explanations for a whole 7 different modes, only allows me to either pick "interactive" or "performance".
Since I never really need the CPU settings from interactive mode, I actually want to use conservative.
How can I realise that now?
Please feel free to post your battery life stats, I'm really curious.
Sidenote: I have "transparent weather clock" on my homescreen and it seems to need a lot of battery. Does anyone have a recommendation for a lightweight & goodlooking homescreen widget?
The kernel for that ROM only contains two governors, please do not use performance because it only uses your max frequency, which is bad for temp & battery life.

Ok, thanks for the info. I wondern why it only contains those two though.
I'd never use performance, interactive already provides more power than I need.
I'm just looking for a way to actually use the conservative mode.
Something weird just happened to me: my phone was at about 38% and when I looked 1h later, it was pretty warm and powered off 1min later because battery had dropped to 1%.
I think this is pretty weird. I did not use the phone in that hour and had no apps running.
As illogical it might sound, my first suspect was the energy saving mode I enabled. I dont know why but I think it messed something up.
Does anyone have similar issues or any useful advice for me?

The developer believes those to be the best choices, I have no clue why. Interactive mostly stays near the max freq & makes my phone uber hot like an oven. Feel free to use Render kernel, its in the general section.

Thanks for bringing that kernel up, I've flashed it yesterday and am delighted. Will try the release from today now.
BTW my low battery life is gone now so thanks again.
Guys, i need your opinions -
How do u think - what is the best CPU governor for maximum battery life ?
The possibilities are in the poll.
Keep in mind, that different cpu governors have different modes, so it will be advisable not only to vote for your favourite, but also to mention in the topic your prefered profile for the respective governor...
The mods for the poll are taken from arter97kernel...
that's how I use when I need that the battery lasts longer and gives me results.
sometimes even put the processor speed to 1000MHz .
It gets a little slow but it can handle
I forgot screen cpu but I have at 1400MHz and undervolt light
Hey ^^
well i prefer zzmoove with the zzmoove battery yank profile on Boeffla kernel 2.8 for Slimkat (check my Profile for more Infos: Link). It runs smooth, gives me more then enough Performance and also good Battery Saving. It also features a frequency lock when turning off the Screen and limits the max Freq to 600 mhz which is perfect if you want to run downloads or something similar without problems in the background and your screen is off, but also gives you good powersaving. Unfortunately if you hear Music it can stutter in zzmoove because of the Hotplugging functionality even when the screen is off. To solve this problem you have to turn off the Hotplugging Functionality at Screen off (i read that somewhere, but forgot where).
