Mytouch 4g Setcpu Optimization

So I've been searching the forums for a good thread on optimizing setcpu for specifically the Mytouch 4G. I couldn't find one so after i read up on it i created this profile. The tweaks that I've found make this run very fast and gets me easily 18 hours of battery life, and that is with moderate usage. These setting should work for most if not all devices. I don't get any real noticeable lag even when turning the screen on. I'm Using SetCPU 2.1.0 on a Grankin01 Kernel on a Stock ROM, and I'm also using "Autokiller Memory Optimizer" using moderate preset. Hopefully people will post there profiles anyway here it is.
Here is the thread for the Kernel I'm usinghttp://forum.xda-developers.com/showthread.php?t=876848
and here is a link for setcpu basics.

Alright here are my most recent setting I've been running.

I get around 20 hours of battery life on my phone with moderate use my set CPU settings are
Overclocked to 1.5 ghz minimum 245 ghz
Battery below 30% Max 1 ghz min 245 ghz
Screen off max 245 ghz min 245 ghz
Latest Cyanogen mod Alpha 7.0

I use max 1113 min 245 scaling on demand...screen off min 245 max 350
MT4G + CM7

Pretty sure this is in the wrong place. I guess you read up on everything except where would an appropriate place to post this be.

louie i dont know what to make of your preset here... Either you are running your phone incredibly slowly or you have forgotten a 0 on the end and are crazy OCing it...
Have mine set at 76800-1113600 on demand and I demand a lot and average about 8hrs. CM7, zinx kernel,with superpower.

I've been trying to get profiles and triggers down except I use CPU tuner inserted of setcpu. Is it possible to over clock yet still save battery? I doubt that somehow lol. If anyone can post full settings that save battery but still runs well I'd appreciate it. Ill copy one of you guys.
Questions though. What is all the governor stuff like performance, conservative, on demand, etc? What are the thresholds? What are the min max standards? Like if I have 300 and 1500, which does it user and why? Those are the only things I can't grasp

Check out this link it has all you'll need to know http://androidforums.com/evo-4g-all-things-root/210253-setcpu-guide.html
What you want is your device to throttle based on the load being put on it. When you aren't doing much i.e. reading a text it should be clocked at 245760 for example because that's not a demanding task. and versely when you play a graphics intensive app or something, it should use just over the maximum amount of cpu power needed to run the app so the app runs smooth. but wont waste battery by overclocking to 1708800 when only a speed of 1017600 is needed. For this i use "conservative" on SetCPU because it will allow more customization.
My advanced settings for SetCPU are as follow. i haven't use CPU Tuner but hopefully it's similar.
Sample Rate you want kinda low 200000 is what i have and i don't get much if any lag.
Up Threshold is at what percentage of processor usage that the clock speed is increased. for me its set to 60. in other words at 60% load on the processor it will start to increase the clock speed.
Down Threshold is the load percentage where the clock speed will be reduced. i have mine set to 33.
Ignore Nice Load will just ignore nice processes. This includes system i believe. i have mine set to 0.
Grabbed this from a mac forum but it should apply.
"A process's priority is determined with a complex formula that includes what the process is doing and how much CPU time the process has already consumed. A special number, called the nice number or simply the nice, biases this calculation: the lower a process's nice number, the higher its priority, and the more likely that it will be run."
Frequency Step is how much of a jump the CPU will take to meet the load. mine is set low, (12) because most processes and apps wont need a whole lot of boost to run smoothly. For my device on average it will be under 768000 which is what you want and is where the battery saving really comes in. Because the CPU is under-clocked most the time its using a lot less battery but is still running everything smoothly.
A lot of people set there devices to ondemand because it's, "very responsive." although true its responsiveness comes from big steps in clock speed as opposed to the small ones that will most likely get the same job done. i.e. a clock speed of 902400 is more then enough to run the process quickly ondemand will jump to 1708800 to handle the same task.
copied from the above link at android forums.
" * 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 the CPU load. This governor is recommended for stable benchmarking.
* 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."

Please post in General section, not dev.

Well i changed my setting a little to be a bit more responsive and i haven't noticed a increase in battery usage. I set my max speed to 1516800 and min to 368640 and its running quite nicely.
Anyone else getting good result with the conservative setting?

Edit: I've been using my phone for the last 12 hours I unplugged it this morning and have only plugged it in to pull a screen shots with android commander then unplugged it and my battery is at 53% I've watch youtube, txt, made calls, taken pictures ect, ect normal crap, and its running strong. I've made small adjustments on some of my thresholds but they are mostly similar.

What version of SetCPU are you using? In mine I don't have the threshold for down, and my sampling rates are way different. Mine is set as from install at 50000. Running cm7alpha.

Is there a way to change voltage? Frequency rules saves are minumum on cellphones.

I'm using Setcpu 2.1.0 and I'm using a stock OC Kernel from Grankin01 and u have to set the profile to conservative.

Frequency rules saves do save a lot of battery. Combine with undervolting and memory optimizations and you'll get big saves. But no setcpu is solely for cpu settings.

Whats the most stable speed to run this at?

So far i haven't had any stability issues on the Grankin01 Kernel. They ironed out most the stability issues in the Kernel its self. I do however keep my main profile around 1708800 - 1516800, generally 1516800, and min is set to 368640 and I've had no problem not even a signal freeze or crash. I've also run at 1708800 for most of the day plugged in and no issues other then heat. So i think is up to mostly prefrence.
I'm using a stock rom with bloatware removed and as i mentioned the Grankin01 1.7 OC Kernel.

Here is what I'm talking about. Sometimes the auto detect or something is wrong and I get this screen instead of the one you get. I don't understand why. I change ROMS a lot and I don't know if it is ROM specific or not. I'm currently on the cm7 preview from Zinx. Although I have seen it on other ROMS also as I posted before. Here is a pic.
Ignore the dropcap2 as I had just used it to take the picture.

Looks like from your screen shot that the profile SetCPU is using is on On demand, interactive or some default. What Kernel are you using? that may be the issue. If not a kernel issue. Then it may be a issue with CM7 and how SetCPU interacts with it. try disabling all your profiles and make sure that your main profile is for sure set to conservative.
Nothing else make a backup and try a different Kernel. Grankin01 has a few great ones and even a CM7 kernel with tunes and tweaks. As well as Gorilla. but id try the CM7 Kernel Grankin01 has first my buddy is running it and hasn't had problems. Just make you do a full backup to avoid a FUBAR situation.

You are right it was the main profile was set to on demand and when set to on demand these available options change.
As far as kerenls go I have not had good luck with Grankin CM Gingerbread kernels but he is working on a fix.

setcpu

any good sensation guides for getting setcpu to work?
thanks

Setcpu should be self explanatory since we now have root. You set the frequency you want the device to operate at. That being said if you are looking to OC then you need a kernel capable of overclocking

but what option do i select when i first start it as the sensation is not listed

I too would like to know.
Sent from my HTC Sensation 4G using XDA Premium App

i think that there soon will be a update. so that we can select our sensation directly. but till than you have to select the tegra2 device.

thank you very much

decided to use this custom freq list that goes upto 1.19ghz so just under the sensations max threshold
put into root of sd and select the custom option

Thanks but this is stock, overclocking is making it do more than it should.
Thanks for the file tho, i'll modify that and see what i can get out of it.
Cheers for the building block
Went on with increments of 38400 however, even though the slider will show 1.5 the actual speed is still restricted to 1.18ghz
Bit weird, i've got no experience of creating these set cpu scripts so i really don't know what's the matter with it, i think the next increment needs to be a different number, as before 38400 it was something like 19000 roughly.

the speed is restricted by the kernel so you would need a Kernel that supports over clocking.. these should be everywhere shortly now most have s-off, I just used the stock for now to manage power i,e when screen is off, use 1/4 of the cpu (saves battery)

Undervolting

Does anyone know the ideal settings for undervolting the sensation without causing any problems?

Not really. As faux say not all chips are created equal. I've seen up to an amazing -150 but my phone can only handle -50 stable and -75 sometimes with a reboot or two.
Sent from my HTC Sensation 4g using xda premium

Mine handles -100 just fine, but yeah,others can only go -50. Just use system tuner and hit the -12.5 till your phone freezes, then when it restarts go one less and see if it's stable. That's what I did.
Sent from my HTC Sensation 4G using XDA App

I'd also suggest keeping the Max Clock at a consistent value while you play. E.g. UV -100mV might work well at one Mhz then fail at a higher value.
Mine seemed to work consistently at about -100mV, then again I tend to UC unless I'm running CF-Bench or something

Should I only need to concentrate on the lowest and highest clock speeds it's been set to use? Or will I have to undervolt all other frequencies between the two? Not sure if it increments on usage, or simply toggles between the min and max.
If it does increment, how can I test it's stability on the other frequencies if I can't tell what frequency it was using at the time?

Just tapped the -12.5 button a few times, and it reduced all of the sliders. It's -100 now with no apparent issues as of yet.

May I ask the reason for undervolting?

Mainly to save battery. Altho I have found that it is quite negligible. It may also help with phone heat

I run faux latest version 2.7 beta and I see his scripts to undervolt and the lowest I see it too go is -75 how are you able to go lower to -100.... ???

I think it varies from phone to phone, mine too seems happy enough -100.

If the phone hangs/boots below that level then with the Phone/Kernel/... that's the limit.
I created a GScript script (well a sh script) to U/V after a reboot. I didn't want it to do it automatically as you'd end up in a boot loop. Just hassle to fix. The reason for the GScript was to remove it from the various CPU controllers I'd tried, I ended up just using the CM7 one to control the CPU.
Faux has the command to do it globally (across all frequencies) or individual frequencies. TBH I never bothered with individual ones.
The bottom line is, do what you and your phone are happy with.
EDIT: meant to add you can check the actual value manually. I know the Faux one (same post as the scripts above) but if you are using a different kernel it might be in a different place.

[Q] Good kernel for CM11 which increases thermal throttling temps?

Hello
I am new to this forum and am a long time CM user which I am using on my phone at the moment. However, having discovered the aggressive thermal throttling on this phone (CPU-intensive tasks seem to throttle the max CPU speed down to 1190 MHz very very quickly, before the phone even gets warm), I'm trying to find a custom kernel that will work with CM. I don't care about any fancy features such as S2W or DT2W and if the kernel allows these to be disabled then that would be even better. Basically looking for a reliable, stable kernel that can be configured to be as close to stock as possible, but which would stop the aggressive thermal throttling.
Thanks

Hi, and Welcome!
I'm afraid that your post likely will be considered a "Best ROM or kernel" thread which is not allowed. It's usually suggested that you go over to the development forum and try out kernels for yourself because everybody's needs are different, and so on.

Yes they are compatible too, for ElementalX choose the right version. Both have thermal settings.
There is also: http://forum.xda-developers.com/showthread.php?t=2649458 and http://forum.xda-developers.com/showthread.php?t=2633955 (almost the same kernels apart the Toolchain), compatible with CM/CM based rom with thermal control too.

All you do is make it "best kernel for specific criteria" then. Mods see it all as the same thing.

I'm giving ElementalX a try for now. The mods can feel free to close this thread if they see fit.
Thanks for all the replies.

before this gets locked you need a CAF kernel, Chaos kernel comes to mind, they do nice work. Comes with NXT tweaks which allows you to customize almost everything including temp.

I tried all possible CM11 kernels and Chaos kernel has in my opinion a very nice CPU load management.
Other kernels will stay for several seconds in max frequency after a power demand which result in higher CPU battery drain.
Bricked kernel was also excellent in that field and super responsive but the developer takes a break at the moment so the kernel is not usable for the CAF Version of CM after 25.01.14 without further modding and the AOSP mod for CM CAF is producing some weird behavior on my phone so I go for Chaos and CM at the moment.

I found Elemental would keep upping the minimum CPU to 1267 instead of 300, so at the moment I'm trying out NexXxt as @viking37 linked above, and using Trickster to configure the temps it seems to be working pretty good.

It's normal, it's how Mpdecision from Qualcomm works (for smoothness purpose). Each time you touch the screen the min CPU freq is increased to 1,26 Ghz. In fact the apps reads this at the min CPU freq because you touch the screen to open it. When you stop to touch the screen the min CPU freq will go back to 300 Mhz, the app needs to update the reading of the min CPU freq too but with Trickser Mod it seems it stuck at 1.26 Ghz all the time (for the reading only) but your min CPU freq is 300 Mhz when you don't touch the screen. You will see better this behavior with an app with "live reading CPU freq" like PerfMon or System Monitor.
You can use the "lock frequency" setting in Trickster Mod after set your min CPU freq to 300Mhz, if you want.

Kernels not sticking to settings

Hi I had this problem with one kernel and put it down to that. The same thing however has happened with others.
Has anyone else had this problem? I've used Trickster mod donate to try setting the frequency. Even with the frequency lock on they jump. They seem to jump to random frequencies, but 1.7 is the most common.
Can someone recommend one that does not do this and is good on battery?

What do you mean exactly? Do you mean the minimum frequency jumps up? If so, yes this is called mpdecision and is present in stock based kernels, unless they explicitly give you a way around it.

It's not that. The kernel I'm using has a scaling range of 300- 2265. I'll set these as it's limits but both ends will move, sometimes to the same freq. 1728 is what they jumped to when I set them just now.
I'm not talking about where the scheduler moves to but the upper and lower limits it has to move about in are what won't stay.
