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.

I get 24hrs if I put my phone away! 6hrs on average lol. Cm7 stock kernel. Grankins breaks youtube everytime. Screen off 328 max 248 min. On demand.

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.

Using 2.1.0 and I have all the mentioned settings Bob

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.

Instructions for using swap
For a swapfile do something like this.
dd if=/dev/zero of=$Swapfile bs=1048576 count=$Size
Where $Swapfile is the location of the file you want, and $Size is the amount of mb for swap you want to use.
Then type
mkswap $Path
swapon $Path
Replacing $Path/$Size with your own values of course, so if I wanted 20mb of swap I'd execute the commands
dd if=/dev/zero of=/sdcard/swapfile bs=1048576 count=20
mkswap /sdcard/swapfile
swapon /sdcard/swapfile
Governor exlainations
Toasty makes one transition to the max speed and stays there(benchmarks only usually)
Batterysave! sits at the bottom and when the cpu load increases past the threshhold it scales up to the next speed and takes another load sample and keeps doing that(best on battery life/performance ratio)
Ondemand sits at the bottom and when the cpu load increases past the threshhold, it scales ot the max speed then takes another load sample and scales down accordingly
Powersave makes one transition to the bottom speed and stays there
Smartass(Quoted from another author http://www.ziggy471.com/2010/11/07/smartass-governor-info ) - "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!"
Scary - A new governor I wrote based on conservative with some smartass features, it scales accordingly to conservatives laws. So it will start from the bottom, take a load sample, if it's above the upthreshold, ramp up only one speed at a time, and ramp down one at a time. It will automatically cap the off screen speeds to 245Mhz, and if your min freq is higher than 245mhz, it will reset the min to 120mhz while screen is off and restore it upon screen awakening, and still scale accordingly to conservatives laws. So it spends most of its time at lower frequencies. The goal of this is to get the best battery life with decent performance. It will give the same performance as conservative right now, it will get tweaked over time.
Governor strategies
Conservative - Upthreshold 85, downthreshold 60
Smartass - Sleep max 245760Hz, Ramp up at 384000Hz at a time, up threshold 90, downthreshold 60
Scary - Upthreshold 80, down threshold 45, sleep max 245760Hz, sleep min, 122880Hz
Recommended apps =)
Zdbox - Great toolbox app, just don't let it run in your notifications bar, it's a cpu eater
Setcpu/Nofrills - Apps that help manage your cpu/profiles/ect.(I don't use them but they're pretty okay)
Perfect system or Elixer widgets - Widgets that monitor battery, current, cpu%, cpu speed, and more(Great for battery guru's)
Adw ex - Smoothest/fasted/lightest ratio in a launcher I've seen so far, and least cpu intensive(for me that's a big thing so the cpu scales less)
Colorize widgets - Great widgets to replace the lpp ones for those converting to other launchers.
AppMonster(pro or free) - Great backup utility, automatically backs up all apps.(I like it better than TB)
GPS Status - Great application for finding satalites near you and helping get a quick lock.
Any go dev team app - Great dev team, all their apps are worth looking at.
Frequently asked questions
Question: My phone is boot looping/not booting on the released suv, what do I do?
Answer: Your phone cannot handle the super undervolted values, you will need to flash the stable undervolted kernel
Question: My phone is running slow on the batterysave or scary governors, what do I do?
Answer: Set your minimum speed higher, those governors spend a lot of time at the lowest values
Question: How do I flash this?
Answer: You probably shouldn't be flashing one of my kernels if you don't know how(Mine are unstable =P)
Question: I'm not getting the amazing battery life/benchmark scores that others are getting
Answer: Well, every device is different, so you may not be able to score as high as some others, but you should get close at least, and the battery completely depends on usage patterns
Question: My phone can't clock to 1.8ghz, or some of the other higher values but does fine on the lower ones
Answer: Every device is different and not all can handle the same speeds/voltages, you are probably better off staying away from the higher speeds, I enabled the speeds but hope that you all are mature enough to handle them
Locating cpu% eating applications.
When in ADB shell type the following

Scaryghoul are the reposted links any different than the old kernels you had up the first time? If not, the suv build would boot and run, but after using the phone after awhile for cpu intensive tasks it would lock up and require a battery pull. Im wondering if just a tiny bit more voltage would solve this problem.
On the stable build, it would run a minute or so and always lock up and require a battery pull..

When Source Code is released will you make a suv kernel for the Gingerbread Update i loved it on froyo and mikshift and gave great battery life.

The source code isn't actually the issue right now. Lack of motivation mainly, I would consider it more if I hadn't deleted my toolchain from my dev station, can't be bothered to get another one setup right now.
When I get motivated again I will, I honestly don't use my phone much anymore(maybe pick it up once or twice a day).

What does Smartass scaling do?

I know this is probably a noob question and has been asked before (i've tried searching but to no avail). How does Smartass V2 go about setting cpu speeds? What is it comparable to?
Thanks in advance.

Thats the definition of SmarAss Gov, some kernels support smartass other dont, where smarass is not supported your choice is ONDemand its kind of the same with less tweaks

Hi, sorry for an even noobier question, but I just started with all this rooting and custom ROM stuff. How do I go about setting the kernel to use the SmartAss V2 algorithm?
I just flashed this kernel [Kernel]CM7/AOSP[2.6.35.14](v0.1.2)OC~1.78GHz/BFQ/SLQB[Sep-11]. The dev states I cant use setcpu, but then goes on to mention the use of SmartAss V2 among others. I tried to access the Performance tab in cyanogensettings->performance->cpu settings, but it FC. Tried looking around the forums, but can't find anything. Tried posting in that thread, but apparently i'm too much of a noob.
Edit: Kinda went digging through the root explorer, does /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor = ondemand mean that its using SmartAss?

Governor, Scheduler and frequency on Fallout V5.0

I've searched the forums for a while now and read up on these topics. However, I cannot seem to come to a conclusion about what settings to apply.
I've messed about with them. When I selected Conservative as my governor and SIO as my Scheduler, any additional CPU work (playing a game) would cause my music player application to stop. So I'm guessing it was holding the CPU back a bit.
My current settings goes as follows:
Awake:
CPU Max: 1024000
CPU Min : 245760
Governor : SmartassV2
Asleep: Same as awake(asking for trouble?)
I/O : SIO( I have read in a post that this was one of the better ones)
ROM : Fallout V5.0
Kernel : Fallout 3.0.42
All changes were done using Fallout Tweaks
Now, my main question...
For day to day stable use, what settings would you recommend ? I don't mind over clocking to 1.2Mhz(That should be safe, right?) but I don't understand which Governor, Scheduler and frequencies to use. I understand that there is a specific way in which you pair Awake and Asleep Governors and that some combinations are bad but I have no clue what this is. I'm looking for something that will keep regular phone use smooth and avoid lag but battery consumption is important. I know that this is asking for the best of both worlds, but take into account that I'm not asking for any heavy duty processing... Just smooth scrolling, messaging, browsing, music playing etc. without them forcing the other not to work (As stated in the problem above)
Well, now that thats over I would also like to suggest someone write a post involving these issues, if possible. In my searches, I have found information detailing the Schedulers and Governors(For other phones) but these just explain how they work and not definitively explaining which is better for a specific use and how they should be paired in an awake+asleep state. One specifically for us Desire S owners would be nice.
As such, it would also be nice to understand what is the difference between these awake/asleep states and why a certain scheduler should be used in each.
I don't mean to sound demanding or rude but perhaps some of the gurus on here have the time and would like to help noobs like myself or guide me to the correct post. Thank you !

I use new amida's kernel with this settings:
Awake:
CPU Max: 1497 Mhz
CPU Min : 768 Mhz
Governor : Brazilianwax or reaper if you use the fallout kernel
Asleep:
CPU Max: 768 Mhz
CPU Min : 245 Mhz
Governor : SmartassV2
With this you can get a great performance for gaming and save battery during sleep
Sorry for my bad English

i am on fallout also...currently i am using intellidemant min/ max 245-1024 awake and 245-768 smartassv2 in asleep....basically the governor are the same i guess no matter from which device....my current setting quite good with no lag...btw i am using noop i/o scheduler...

That is relative, you need one governor or other depend if you want performance, battery duration or a balanced combination...try one and another to get your best combination of them :fingers-crossed:

[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.

Only Chaos kernel is compatiblewith CM atm afaik because its a CAF based kernel.

I probably will do that, but I thought this might not fall in the realm of "best kernel" because I have listed some specific criteria...

I'll give that a try. From browsing earlier I noticed that n30Hammer and ElementalX have separate links for CM11, I figured they would be compatible.

Oh, believe me, I think your post is fine. I just wanted to give you a polite heads-up before the more zealous members started chiming in.

Hi,
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.

Not good option. Only locks core 0. Core 1 still affected.
Only full workaround is delete /system/lib/hw/power.msm8974.so

Hi,
Yep, right
Old thinking that is income , sorry for the mistake. I edited my post

Just thought I'd report back, been using NexXxt with custom thermal config using Trickster, and have had no problems at all, great battery life and no more throttling.
