According to Franco 700 MHz is the most efficient. I think all other kernels (+ for sure the phone's default from Samsung & Google) have the minimum set on 350 MHz.
Personally I see it being dependent on usage style; if the phone lays idle a lot the 350 MHz should be better. If you keep waking up the phone every other moment then the 700 MHz makes sense.
350mhz.
700mhz minimum is not more efficient.

for francos kernel it might be the case...not others
I think it depends on the governe you're using. when the phone is idle it absolutely doensn't matter (on any kernel) because the cpu shuts down.
when you're using the phone then it depends how the governer manager the cpu to get the task done and race back to minimum freq.
I'm just guessing here but based on this assumption I think 700mhz is better for ondemand/conservative but not so much for interactive.

Franco uses 700 because of the wake lag caused by 350 when using hot plug mod (shutting off cpu1)
Sent from my Galaxy Nexus using xda premium
With 350 or 700 I still get wake lag.
i'm on franco's latest and hotplug is on and my cpu gov is set to conservative and min freq is 350mhz. no lag on waking at all..
180

The cpu may idle in a low power state, but it does not shut down. How can the phone run if the CPU stops running? There is no secondary system that intervenes to start the CPU back up.

that's what I meant. my point is that power consumption in idle state doesn't depend on the min frequency.
But it matters every time your phone wakes up, even if its momentarily.
Only get lag and signal loss when on 350. 700 seems to give me the best sleep and wake time with no lag. I had to learn the hard way. But figured out from reading around that 350 causes some problems on any kernel/governor.

The only time 350mhz gives troubles is if you set the min/max to it for sleep.

I think you have that backwards? OnDemand basically just jumps between minimum and max. Only recently has a 2stage part been added in that you can set to around the halfway point for light load tasks.
Interactive used to be more efficient because it didnt jump straight to max speed like OnDemand does. However with the addition of the 2nd stage in OnDemand, that tends to be more efficient now. Besides, Interactive governors are always buggy on any phone I have used them with.

It does in some ways. It will idle at the lowest speed it can. If you go too low the CPU will drop out and the phone will never wake up or will crash and restart. If you set your minimum to 700MHz then it wont go below that so that becomes the idle speed. And since p=v2*f, the lower your frequency the lower your battery drain.
Actually, stock kernel, onDemand is garbage, and Interactive is best.

it's not as simple as that. when the screen is off the phone enters deep sleep as much as possible which uses (almost) the same power regardsless of min frequency. The phone obviousely will wake up from deep sleep from time to time and that's when the minimum frequency comes into play. For example, for someone who has a lot of applications syncing every few minutes or someone who listens to music a lot with the screen off (which prevents deep sleep), setting the minimum to 350 will be better. Otherwise, the savings are negligible.
This was put to test by someone here on xda (the gnexus general section) by measuring voltage and current through the battery in different conditions.

Guys! What is the best setting for Set Cpu? I need to conserve battery. My battery lasts about 12 hours. Im using a Reflex S 2.04 rom but i shifted to Leedroid 2.4.1. My settings are 768 On demand and 245 max 245 min on demand for powersave.
What is smart ass? How does it affect the system?
On SetCpu, I run overclocked 1200 till under 80%
Then about 80
700 at 70% battery
600 at 50%
I don't wish to run lower, as the desire gets a little wonky below 500mhz
3 profiles. I can get 3 days battery
I use no frills CPU - oc 1114, ondemand governor 245-1114.
Get about 12 he's heavy use, up to 2 days light. Today I have done 3+ hrs train journey with music, browsing and SMS, checked mail, now hanging about on this forum! 41% left.
All other governors are ****. Just use ondemand.

Because they don't work well. When you need CPU power they tend to lag and it takes that little extra longer which does my head in. Whether it's just me I don't know but it is so annoying. I have noticed it when playing games like RoboDefence. That's why I stick to ondemand because it actually works.
for the sleep off what is the best setting? screen off 245 max 245 min on demand? or 245 max 128min smart ass?
With smartass you do not have to set a profile for screen off. Smartass uses automatically the min cpu-frequency you set. So if you set smartass for screen off, you have two "screen off"-profiles. I think that could cause problems. You should set the screen-off-profile on [email protected] to avoid waking up problems, which can occur with this min 128 and max 245 for screen off-profile.

From SetCPU-Website:
ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.

smartass governor – is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works – by taking over the idle loop – is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the “old” minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 – why?! – it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!

I recommend for screen off, 245-128 powersave governor.

Min 128 max 245 for screen off is too low to wake phone up, does not matter which governor you use. Min 128 max 245 with screen off may only work with ondemand governor, but i would not recommend it.
If you want to use min 128 mhz with screen off, you should set max to 422 mhz. As governor i recommend ondemand or interactive. On this way you can avoid issues in waking up the phone and you will still have a great battery life. For screen on you can use min 128 and max 768 with ondemand/interactive. But keep in mind, some phones have problems with 128. If your phone crashes sometimes randomly, set min cpu frequencies in both profiles up to 245.
A little different opinion:
rootSU said:
I use on demand with eviollet kernel min 128 max 245. Only thing that happens screen off is Poweramp, so can't comment for other back ground apps. But wake up is fine and power amp runs fine.
Of course with teh eviolet kernel you can set your own voltage levels so the next frequency up from 245 (384) can be set with the same voltages as 245, so having max of 384 would be no different power drain wise than 245.
Smartass is very bad for waking the phone so I steer clear of that all together.
Once thing that is important to note, using a different governor for screen off than screen on will also slow down your wake time. Changing governors can take time so will produce a lag when turning on the screen so find your governor and stick with it through out.
The most efficient governor for screen off if min and max are the same is either powersave or performance. The reason for this is they as default run at min or max (respectively) so they do not poll the CPU to check for load as they do not care. That said of course, these governors are no good fro screen on use IMHO so it would need a different one which then gives you the governor change issue.

You might want to check this, as I'm pretty certain your 128MHz state almost never kicks in with that profile.
Also, check vdd levels as I think 128 and 245 share the same, so all you get is a placebo, and battery wise you get nothing.

I am pretty sure 128 mhz cosumes less battery than 245 mhz, because clock is lower, even if the vdd level (the tension) is the same.

That's way too low of a min speed, just bump it up to the next (I think it's 386) and you should see noticable improvement.
I'd also suggest the ondemand gov; since it only ramps up to the top speed when needed, then drops it back down again, you should get a bit better battery life.

i read ondemand and conservative governors are od, so using interactive or smartass are better then using others. I will try min 368 mhz but am not sure if it works...
What are you trying to accomplish by messing with the clock speed? Leave it alone at default. Performance difference is NEGLIGIBLE (bottleneck is elsewhere), and all you'll accomplish is eating the battery and burning it up with excessive heat caused by excessive clock.

First of all, I would like to thank you for your comments.
People don't do anything to access root if they don't want to mess device. I am one of them and want to have a device which both has performance and visuality. You offered me to not to change clock speeds. But we know HTC Desire Z is scheduled to work at 800mhz everytime (default). My opinion is just to set minimum clock speed to 800 mhz or something like this. If my device was burn by this clock speed, it was already dead.
Today i tried this clock speed (min 614, max 1382) and during the day it didn't heat up. Moreover, 8 hours passed, i played NFS for about 1,5 hour, made some call and 30 percent of battery left. It seems this clockspeeds doesn't cause battery drain or i couldn't feel it...
EDIT: 13 hours passes, 16 percent battery left (I made minimum 30 minutes of call)
As many of you know, battery life on the One X has been lets say, poor.
I decided to narrow down the problems and try to figure out whats causing it.
I figured i'd download voltage control (SetCPU works also) and underclock the CPU, low and behold......I may have figured out why the battery was dropping so much during screen on standby.
ONDEMAND GOVERNOR!!! It was causing crazy CPU instability. The CPU was constantly changing from 340mhz to 1500mhz (or your max speed) every single second, alternating constantly.
I've changed it to Interactive and it's been much more stable now. When not doing anything, the CPU will stay at 340mhz and no longer constantly ramps up to maxx CPU speed and back down alternating.
Try this out and see if it helps you guys. I'm going to continue experimenting with the other governors, but Interactive should be the best blend between battery and performance.
Also download CPU spy to see what steps of the Speeds have been active the most.
Edit: Changing the frequencies does not do anything sadly. Will need to wait for VoltageControl and SetCPU to be updated.
BUT changing the governor does work and makes a big difference.
Going to Interactive, my battery no longer drains at around 1% for every 1-2 minutes of screen on time leaving the screen on and idle. It drains much more normally.
Tonight I will do the HTC test where you check how much battery drains for 1 hour of screen on time at max brightness. You may feel free to try it out using the dialer *#*#3424#*#* and running battery test.
I will do this tonight and upload my results/screenshots
Update:
Here are the two main tips that I have found out now to help a lot with battery and low CPU usage that is stable
1) Use Interactive Governor, it is less aggressive at ramping up to max frequency and much more efficient. Also more stable and not erratic like OnDemand Governor
2) USE APEX LAUNCHER or something besides Sense Launcher.
I have downloaded Tegrastats to show me CPU usage and have compared between Sense Launcher and Apex. Sense is very resource hungry, and CPU usage is very high. It is almost constantly has both cores turned on and usage fluctuates between 15-70% alternating on the two cores when screen is on but idle. The frequency also stays around 400mhz on idle.
Apex launcher on the other hand, uses 1 core when idle, and usage stays around 10%. It also hovers around 102-204mhz when screen is on but idle. When swiping as fast as possible to ramp up speeds, I haven't seen it go above 640mhz and usage between the two cores is around 30-50% EVEN with both cores vs. alternating 15-70% on both cores with Sense Launcher
Thanks mate
Strange, from what I remember any CPU-tool didn't have any impact on my governor and cpu behavior. Maybe this has changed with the update. So I will have another go
(Just put it on its 7th charge, gotta wait a while..)

I`m not seeing this at all.My phone has been on standy for a few hours..wifi on/auto sync on..ondemand governor.Battery loss about 4% in 3 hours. CPUspy reports no high frequency spikes..highest shown is 475MHz.
I believe in ARHD mike has already set to Interactive Governer.
Set CPU doesn't work it will still go over the max set. I have contacted the maker and he is looking into it hard without kernel sources. Screen shot

You have got the best one.

I wouldn't lose battery with screen off. But with the screen on and not doing anything. Just watching the speeds in voltage control I watched it constantly alternate with 340 and 1500.
My min is the lowest I can set, around idk 50? I don't remember. But it doesn't go that low unless screen off standby. Probably for companion core.
This is just to let people know that ondemand governor acts funky and interactive is probably the best to use.

Sadly true. Don't know how these other people can claim that it's working.

Use voltage control, it's free from the play store.
You can tell the difference between OnDemand and Interactive or w/e governor you choose. OnDemand not touching the screen, you can watch in VoltageControl it alternates constantly between your max CPU and 340mhz (This is about the lowest it goes while screen is on). Then apply Interactive and it will stay at 340mhz and not jump up to the max speed anymore.

Yup, I just checked again and watched OnDemand be very unstable as the Governor itself is somewhat like that.
OnDemand ramps up to the high frequences so that everything is smooth, the only problem is that it's doing it way too easily. Leaving screen on and not touching it, something causes it to constantly jump back and forth between low and max frequencies.
Setting to Interactive or even Conservative makes it much more "stable"
Conservative is really good at staying on low frequences (takes longer to ramp up speeds) but as a result feels very laggy so Interactive is what I recommend as the best blend. (In general, Interactive governor is becoming the standard for most phones. I remember it being very popular on the i9100 and Galaxy Nexus)
So yea, just try out Interactive and see how it works for you. I am no longer draining battery at like 1% for ever 1-2 minutes of screen on time leaving it

Yea I just realized messing with the frequencies isn't working
I will edit my OP
But setting to Interactive Governor DOES make changes

OK i assumed standby = screen off.Switched to interactive on System Tuner Pro....i see less spikes at 475 MHz.
I don`t have time but maybe someone could test for lag between the onedemand and interactive governors. I know for sure that the Tegra 3 works better using ondemand on my prime.
Anyway interesting things gould come from this.

We really need the kernel source released so the devs can get to work.

Interactive is very similar to OnDemand, but it is not as "aggressive" in it's frequency changes.
It is a very popular Governor on other phones and Kernels. So far, I've experienced no lag as it still hits those high frequencies, but less often and only when it needs to.
My main issue was leaving screen on and in standby with OnDemand and watching it constantly jump from low to max frequency which is definitely not correct.
Using interactive, battery drain has been much better and to the norm.
Can't wait for kernels to come out and optimize battery and performance.

I suggest everyone head over to HTCdev.com and post a comment asking for the One X kernel source code release.
I was going to make a new thread until I saw this.
I was able to override the Tegra 3 system using a few tricks which allowed me to change the frequency to my own, plus only allowing 2 cores to come on.
I'm at work but ill post a video soon, you only need setCPU and patience to get it to work.
I monitored this by TegraSTATS in the market for free

Here's a small evidence for now, my CPU is set from 102mhz to 1000mhz. The bottom monitor is Tegrastats, as you can see only 2 cores are running max at 100% at 1Ghz on the CPU benchmark.

Yea similar to hotplug governor except is it always 2 cores for your mod?
Hotplug governor enabled however many cores were needed and disabled when not in use.
Either way, awesome work.

I'm wondering if anyone's undervolted and to what values.
I'm also wondering waht the deafult values are and if they change per kernel.
Is there a way to disable SetCPUs undervolting settings?
Has anyone improved battery life with profiles? On the Eris this was the only way to get usable battery life.
Or not. I gave up undervolting after I actually compared battery life at stock values vs undervolted (on my old phone, sgs4g) and discovered it does nothing for battery life.
Edit: undervolting "might" marginally increase standby battery life, but considering how good this phone already does... it certainly won't increase actual screen on usage.

Depends how low you under volt. Got more battery life, maybe about an hour, after finding optimal battery life on my gfs Gnex.
If you don't under volt correctly, of course it won't improve battery life.
From my sexy white, Nocturnaled HTC One X
If you're not overly comfortable with undervolting, then using one of the many kernels with Smart Reflex will do a mild undervolt for you. If you are comfortable, then the only way to find numbers good for your phone is to try and test. I tweaked mine down to the point that I was occasionally getting hot boots when the screen was off and media was playing. Tweaking the numbers back up added the needed stability. Even little things like kernel or ROM revisions can change what voltage is or isn't stable. Another example is that when I updated my Jellybro CM10 version the other night, along with updating leankernel from 4.1.0exp3 to 4.2.0, I had to increase a few of my voltages to avoid hot boots.
Just for example numbers, here are mine:
Code:
1350MHz -- 1200mV
1200MHz -- 1150mV
920MHz -- 1050mV
700MHz -- 950mV
350MHz -- 825mV
These numbers will vary from device to device and even between ROM/kernel combinations, so don't use them as hard fact.
Thanks. On a phone like this it might not make a huge difference but on the Eris (Where stock battery life could sometimes be 6 hours if you actually used your phone) an undervolted kernel with setcpu could turn those 6 ours into 48.
Thanks Cilraaz, I'll try those voltages out and benchmark a bit to see if they're stable for my system.
Two things I can say for sure:
1. you will have very limit battery gain by undervolting with Gnex, no matter how low you try.
2. undervolting will bring some stable issue if you get too low, like lose signal and reboot.
I am using Kernel Franco GPU 384 Stock rom on my 4.1.1 and did undervolting
Current configuration:
384Mhz
950mv

729Mhz

I did not change the frequencies of overclocking, because I'm not using them.
I felt an improvement in battery consumption unless the unit is heating up.
Just curious - what kind of profiles are you using? I have a "Screen off" that's 350min and 700max. I figure that's fast enough f someone calls me.
I've read many times undervolting isn't worth it.

I'm using the following with SetCPU: default (1350MHz-350MHz), charging, CPU temp > 64, and battery < 35%.
If you're using a kernel and governor that support hotplug, then you likely don't want to use a screen off profile. The combination of the two can tend to cause sleep-of-death or hot boots.

Most people don't want to spend the time to do it right.
I'm actually not used to the new kernels. I haven't messed with my eris in about a year and back them there was "smartass, on demand, performance," and some other one that clocked down instead of up
Can you explain th escreen off profile causing issues? I don't even know what hotplug is lol I've been out of Android for a long time.

Hotplug disables one of the CPU cores when the screen is off. Some governors, like hotplugx, will also attempt to disable a CPU core during periods of low CPU usage. For some reason, this combined with a screen off profile can cause some problems. I assume it's because of the "screen-off-max-freq" that Imoseyon mentions in the quote below.
Personally, I prefer the interactivex governor with leankernel by Imoseyon. From his kernel thread:
With interactiveX V2 (for gnexus), things are a bit different, since gnexus has built-in support for screen-off-max-freq for all its governors. I took the new interactive code in gnexus, added early_suspend support (screen off/on trigger), and then added logic to the code so the governor uses the phone's built-in hotplugging capability to turn off cpu1 when screen is off (and then turn it back on when screen comes back on). Cpu1 goes offline entirely - no idle, no sleep.

I think undervolting helps - my phone is running 728 - 1228 using the interactive governor, with voltages of 600 mV, 700 mV, and 800 mV (728 MHz, 1036 MHz, 1228 MHz respectively) and I haven't had any issues so far. I know there are some reports that say undervolting doesn't help much, but those are when people undervolt by like 50 mV, whereas here I'm going like 400 mV under lol. (Yes, smart reflex is off).
Thanks Cilraaz. Good to know.
So turning the screen-off profile could improve things? Honestly, my system does fine at 350mhz with screen off. Turning a core entirely off would probably help though.
If I use hotplugx governor that would disable one core when the screens off, right?

Hotplugx will disable a core when the screen is off or when there is low system load. Depending on your kernel/governor choice, other governors may do it also. On leankernel, for instance, interactivex will disable a core when the screen is off, but not on low system load.
Ok, thank you.
I haven't done any comparisons of before/ after since I undervolted/ underclocked first thing. But I was browsing for hours while listening to music while talking to a friend with GTalk. talked for about 1.5 hours with someone, Left it on overnight (10 hours), woke up, used it to talk (voice to text) to someone via GTalk, and it's 3:25PM right now and I still have a fair amount of battery life left.
I'd heard mixed things about the battery on this so I'm happy.
My voltages:
1650: 1300
1520: 1250
1350: 1175:
1200: 1125
920: 1000
700: 925
350: 900
I stress tested each one without a crash.
