SetCPU vs. CMSettings Built-in CPU manager

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.

[Q] Suggestions for setcpu range on rooted a500

Can someone please suggest an overclocking range for use with setcpu? Id like to gain some extra performance and dont mind a higher battery drain,but I am concerned about going too high and cooking the tablet
Any suggestions would be appreciated, thanks!

i believe you need a custom kernel or ROM to overclock; SetCPU will definitely let you underclock just rooted.
Once you have a kernel w/ OC enabled, I'd suggest starting with 1400MHz, then load a cpu-intensive game & play for 30mins or so. If SetCPU doesn't show the temps going north of, say, 110F/43C, increase the max speed by 100, repeat until temps get past your comfort zone, then drop back to the prior setting.
I was unable to find a max suggested temp range for Tegra2, so you may want to err on the side of safety and/or comfort and aim for a lower max temp.

As stated above you need a custom kernel to overclock, but it isn't rom related at all. I have been running mine sense i was able to load a custom kernel at max freq 1,504 Ghz and min 216 Mhz and have never had a problem at all. Using setcpu you can set profiles to save battery life, like screen off profiles and also use different governors to help battery life. I usually just leave my governor set to ondemand and can't complain about battery life or over heating.

thank you to you both! Much appreciated

Does cpu frequency affects battery life?

The question is simple, the higer the freq. the more battery consumption? i am asking because i cannot see any difference from 1.4GHZ to 1.0GHZ, the battery consumption is the same under oxygen and francos kernels. i would be grateful if the experts would give us some advise or their opionion. I know it is subjective but i would like a second opinion.
Thanks alot guys

If you look with any cpu spy app, you cab see on what clock the processor is used. I mainly have it the lowest and sometimes higher. When you change the max, it should still automatically choose what clock is used, so battery should last as much as before, if not used in high clock.

Probably not much difference, when you overclock, think the cpu voltage remains the same as it is on 800mhz... And the highest cpu freq is rarely even at use...

Well, thanks to most devoted users of U8800, we have somewhat better speed+battery life than stock also. To answer your question, yes depending on your activity the frequency have some impact, but overall shouldn't be huge in change, for example from .800 to 1.0GHz will not affect so much in daily use. However from .800 to 1.5GHz would make a somewhat huge gap difference. This doesn't mean it will drain faster if you do same activity as with .800 to 1.0GHz, for example check the watch, answer sms or few "entertainment" breaks. Only when using the phone over a longer period of time that's when you will notice the change of battery life with different frequency. Hope it clears up most hums and huhs for you. I am pretty sure some expert within this field will give a better explanation than me.
Bye~

higher freqs uses more energy, but lower uses less energy but do things slower (so energy consumption is longer). ALSO imo - if you set cpu to 1Ghz the lowest value so it always is 1ghz - it will not consume the same amount of energy if it's in idle mode - it's like your laptop - if cpu is working only in 4-7% of it's power - then the power consumption is lower no matter what freq - how do we know that? - because of heat - the more heat you get - the more energy was used. and when cpu is idle - it will not be hot.
So the answer is - if it saves then in VERY minimal amounts. But even so - i use min freq - 360mhz. it's good for me i do not get any lag so i use it.

I use the "Root System Tool Free", option CPU and I see the graphics of all clocks.
For ex. now at 245 mhz ->46%, at 368 ->10%, at 768 mhz ->18% .... and at 1612 mhz -> 1,8%, at 1804 mhz ->4,9%. Not very mutch use at 1804.
Oxygen-test-140911 + Franco.Kernel1709#1. Clock at 1804 Mhz by Menu-settings-cpu ... and smartassV2 (no profils).
The battery, I charge it all 24 hours. But I like my work... and testing things. When then will dead...I see...

But I like more the Root System Tool, because has also a Linux Console. I use it when I want make some cmd's Linux in #. I don't like the Terminal Emulator.

Well, there is a "catch" somewhere in there. The frequency does indeed affects the power consumption of the CPU and greatly at that too! But the thing is, your CPU is not the worst enemy of your battery life. Even though CPU consumes more power in higher frequencies, it still can not compete with what your screen LEDs or your GSM module or your GPS chip consumes leisurely. So, if you're looking at the overall picture -meaning if you're wondering if it will affect how long you'll be able to use your battery in your phone- the answer is, "yes but not so much". Especially if you're switching the CPU frequency based on the demand (like using smartass or on-demand governors)
Here are the thing that sucks your batteries life juice like a vampire :
Your Screen (especially background LEDs)
GSM module (talking, using GPRS/Edge/3G network communication)
GPS chip
Wireless module (this also includes Bluetooth, even though it does not consume as much as Wireless network access but everything is relative -think about playing music through A2DP headphones compared to having your wireless network active but not using it much-)
(oh yes, I love to use lots of parenthesis -and even this hyphenation thingy- )
Correct me if I'm wrong about anything by the way ..
Regards ..

I did some experiments with a msm8250 a while back and there's a graph here:
http://forum.xda-developers.com/showpost.php?p=14324649&postcount=3786
msm7x30 should be fairly similar though the graph is probably shallower since it's a smaller process size.
The CPU uses no power when it's not in use, even with the display on, the CPU is powered down completely when idle (power collapse).

SetCPU best speed

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

I'm at 691200 on smartass governor with 245000 as min on Rcmix rom

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?

Best Settings For Snappy Fast Perfrormace/Overclock? Help

Im looking for someone to tell me what they think is there best settings to be used in there prefered app for example setcpu,faux123, do you overclock and to what settings, what has worked for you guys
i generally dont use my phone to much in a day so battery last the day so i dont mind it being overclocked when im using it if it means it runs faster but drains battery, some suggestion please, im a novice
no flames about i used the word 'best' im looking for opionons thankyou if you help

IMO, no overclock is required. The phone is fast and snappy enough.
That said, I underclock the minimum frequency and undervolt throughout the frequency table.
This ensures that I get better battery life, without any decrease in performance.
I'm running CyanogenMod 10.1.0 Stable Release.
I'm using franco.kernel r161, and his companion app - franco.kernel updater.
The following settings are giving me great performance and battery life.
CPU Frequency Range : Screen On - 384 MHz - 1512 MHz, Screen Off - 384 MHz
CPU Governor : Interactive
GPU Frequency: 400 MHz
Frequency Table Undervolt : -125 mV throughout
Disclaimer - This is for a {fast} binned CPU. Check your device's CPU binning via this link, and do some trial-error to find the perfect undervolt for your device.
Good Luck!
