Hi all, i'm looking for an app that lets me set some default speeds based on CPU's working needs, does something exist?
I remember i had it on my Diamond, i could set the speed with screen off and on, or set it to increase the speed if the CPU has to do lot of work.
I've found LeoCPUSpeed but it seems i have to mode the slider every time i want to change clock...
Just to repeat your request to see that I understand what you want:
You are searching for an app/tool to do something what your HD2 already does by its own?
Yes, but i'd like to tell it when use determined frequencies and which frequencies to use
That's what I was afraid of.
Unfortunately I also know LeoCpuSpeed only for adjusting CPU clock rate.
As you have already determined by yourself you can only switch between fixed CPU clock rate or a dynamic range.
But do you really need something like that?
Isn't your HD2 fast enough?
How about the balance of battery consumption and power/speed?
Have you tested custom ROMs, especially Artemis? That is really fast compared to STOCK ROM.
Yes, it's a lot fast That's the problem, i'd like it to run at a slower clock if not necessary, my aim is to save battery. I don't think a 1Ghz CPU is really needed, my old Elfin has a 200Mhz CPU and for base purposes was just good. I'd like to use a lower clock and let it go to 1Ghz only when needed.
Not sure where, but i've read a few people stating that the usual CPU frequency for the HD2 when it is awake is 768MHz and it only boost to the full 998MHz when it is in need. For windows mobile i don't know how you can determine the range of a dynammic scale (only static as you have been told). However, for android, SetCPU would be what you are looking for. But droid is not what you are looking for (sorry for a pseudo Star Wars reference ).
Yes now I'm on Android and i've got SetCPU, i already knew it on my Hero, but even if on my Diamond i got an application like the one i'm looking for now, it seems that for the Leo, on WM, there's nothing to do
It's is like ei05035 posted, the HD2 doesn't run on full clock rate all the time.
Sir Sternas brought along with Artemis a small tool which shows the CPU usage, see attached pic.
So, I'm not sure whether you can optimize the windows system defaults for cpu usage and battery consumption by setting own values.
Please have also a look on this post, which announces the end of development for LeoCpuSpeed.
I know it can be done because i did so on my Diamond, maybe it's a problem with Snapdragons

Hi everyone,
I recently stumbled upon Hakeem's thread, which details the necessary configurations to extend the battery life of the HD2 running Android. One of the key configurations is to use SetCPU to underclock the device from 1GHz to around 600MHz.
I really want to try it out, but my bf told me it might be risky. He said that since the CPU is now running at a lower clockspeed, it might lead to HD2 overheating if I were to run multiple applications (compared to the default, 1 GHz config). I'm no techie, so I really don't know if what he's saying is true.
Are there any risks associated with underclocking the HD2 using SetCPU? Thanks a bunch!

I have used SETCPU on my device for 1 whole month, there is nothing bad happens and it is safe.
In addition, you can install this app "current widget" or put a SETCPU on your homescreen to track your device temperature. This is the safest way.
Cheers,hope this help...
As opposed to overclocking, underclocking shouldn't pose any risks. You are basicly running your CPU at a lower frequency than designed, so your device will be cooler to start with. Even when maxing your CPU load, by running a lot of apps, your CPU is operating under its designed capacity. It will therefore never get hotter than a stock HD2 running full load at 1Ghz.
Furthermore there are built in safeguards to prevent catastrophic overheating. So basicly its safe and you should have no issues. Except, maybe, insufficient CPU capacity when running a lot or a heavy app.
Hope this helps!

I wonder if this is what my bf was talking about.
But anyways, I'll go ahead and give it a try. Thanks you guys!

He's an idiot. If you make it faster, its generating more heat, if you pump up the voltage it makes more heat. There is no possible way for lowering it to cause it to run hotter.
If you are that concerned, create a profile in set CPUto lower CPU and use conservative when temp reaches a certain point.

FROM WHAT I READ that if you underclock to the wrong level you can damage things that needs a desired amout of cpu ...if not it can stop working i wll find my source and post it later
weird thread. lol you cant damage your hd2 cpu by underclocking or undervolting

Agreed, just turn it back up before playing memory intensive games & apps.
You're all wrong and I dont mind saying wrong section! stick to the topic of "Development"!

My HD2 is locked to 245mhz - 400mhz when on a black screen (so locked.) When in use it fluctuates between 245 - 998mhz depending on usage.
had it this way for months. No ill affects and makes the battery last that little bit longer.
my sgs2 kept getting a little hot and i also felt that the batterylife wasn't bad, but could be better.
so i decided to underclock it to 500mhz and see what happens.
after all, it's a dualcore and 500mhz shouldn't feel like...500mhz right?
but it did feel like 500mhz with everything choppy and so on..
perhaps i just have the wrong concept of how dualcores are supposed to work....or perhaps gingerbread/apps/filesystem isnt yet fully optimized for dualcore? i don't know.
i decided to look for some sort of system monitoring app that'd show individual core usage...like "Tablet cpu usage monitor". but found none
StabilityTest 1.5 sometimes only shows 1 core. probably just the app's problem....
thoughts anyone?
edit: i just realised one thing...though havent tried it enough times to say it's something meaningful. from a fresh reboot, if i don't open SetCPU, StabilityTest v1.5 detects just the 1 core. then if i close Stability Test, open SetCPU, let it have its permission then back out, StabilityTest would then show 2 cores.
I use OS monitor. I found that Wifi Sharing was killing my battery, by takin up 20-30% of CPU time and causing the CPU to clovk itself to 1000 MHz! So using OS monitor, I killed the process and the battery drain goes away (until wifi sharing starts itself up again!)
yer i use osmonitor too but it doesn't display individual cores D:
and yes i probably check my cpu usage about twice a day specifically to make sure wifisharing isnt on and eating up my batt. im surprised samsung didnt fix this with their updates..
im very interested in this too, especially underclock + lower voltage for CPU - could drastically increase battery life.
Try disabling a whole bunch of default apps that come with the phone if you havernt already, details here:
http://forum.xda-developers.com/showthread.php?t=1069924&page=2
And report back your findings ???
plenty of battery threads lets not make another, we know there is a battery problem they say its 2.3.3 related to the dual cores.
As for wifi it might have something to do with your router the dlink dir 655 router was having problems with this phone, i imagine maybe other dlink routers have the same issue.
Get a app called juice defender it shuts of any wifi that is not in use ( when phone is in sleep mode ). it also works with 3g data.
Hope that helped
i suppose im more interested in the dualcore aspects here...rather than the batterylife. sorry i didnt really make it clear
i did search up on "dualcore optimization" here in the forum but there really isnt much about it
for example..what is the state of gingerbread's dualcore optimization? what about apps etc
i think i'll also do some googling myself
I don't think Gingerbread is dual core optimized but the underlying Linux kernel should take advantage of the dual core for multitasking. Every app using multiple threads will use the dual core too.
I stumbled upon these apps by dumb luck and decided to post this for anyone that doesn't know they exist. The dev is Chinese I am guessing based on a lot of his apps being in Chinese. He soes have these 3 apps in full English though and I am glad he does! For anyone that is looking for a SetCPU alternative, look no further. I will be the first to admit that I am not crazy about SetCPU. The app and I don't get along because of stability issues. CPU Master can do everything SetCPU can do but with better stability. I have been using it on both of my Vibrants. I have one Vibrant with the MIUI Rom (1.7.29) with the Bali 1.1.1 kernel and the other Vibrant is running CM7 Trigger Redux #17 with the Bali 1.1.1 kernel. I have had ZERO issues with the phones. Set on boot work flawlessly and overclocking is a breeze. The will give you every scaler that is included with the kernel you are running along with whatever overclock speed is set in the kernel. The Bali kernel supports up to 1.4Ghz and thats what the slider is maxed at. I loaded the Glitch kernel that supports 1.7Ghz overclock to see if the slider adjusts to that speed and as expected, I got 1.7. The only difference between the Free version and the paid version is that you can set and edit profiles in the paid version. For 1.99, its well worth the investment!
The Benchmark app ties directly into CPU Master. It tests everything that Quadrant Advanced (paid version) does PLUS it tests the speed of your SD cards! All of this and it's Free. If you are playing with overclocking speeds on your phone to see where the threshold is on your device, this benchmark will tell you. Through its rigorous testing you will see right away if your phones CPU can handle the speed you are testing. If you lock up during the test, its time to slow it down! On my MIUI Vibrant, I can only go up to 1.3Ghz and beyond that it freaks out. On my CM7 Trigger Vibrant, I can run 1.4Ghz with no problems.
Smart Profiles Free is a great app for people who spend part of their day in places where being quite is important. You can create all kinds of different profiles throughout your day to keep your phone running like the way YOU want it and not worry about turing on and off features. Just make your profiles and you are done! For example, from Monday to Friday I am at work 8 - 4:30 and I want my phone on Vibrate only. During those times I also want my WiFi on to use the company's internet and not my data plan and I also want my GPS off. As you can see you have A LOT of control of the various functions of your phone!
These apps are definitely worth the time to take a look at and try out. For any end user that wants even more control of their phone, they are certainly a fantastic addition!!

Excellent over / underclocking utility!
Yes, sure Antutu CPU Master is really a very good and powerful utility. I bought the pro version and it is worth the money. I am using it in my Samsung Infuse 4G, this allow the device to be underclocked till 100 MHz and overclock up to 1800 MHz, of course with the required Kernel and root access. It can be configured by the readymade profiles that can automatically change the clock settings based on conditions.
The widget which is just two column wide and 1 row height shows CPU Speed, Battery Status and Temperature.It has profiles, default, Charging, Screen off, In Call, Low battery, Temperature over-heat.
For stable clock setting set the minimum to 800 MHz as below this the device goes unresponsive particularly when the screen is off. I am using the range between 800 - 1800 and so far no issues, and it works great!
As mentioned, the benchmark, CPU setting and profile are great features of Antutu collection of software. Thanks to them!
What settings are best for optimal performance and battery life? I don't have any experience with this, and I don't want to screw anything up. I just got tired of my games always lagging, but I don't want a battery drainer. I dont believe I have a custom ROM. Thanks for any and all help.

SetCPU probably won't work very well unless you flash a custom KERNEL. You can mess around with it if you like and you'll probably won't mess things up. One thing I discovered before custom kernels came out is that you can enable the second core by enabling profiles in setcpu. YOu can see that in the menu option of setcpu for "cpu". That may help you in your games. If you set max at 1500 and min 192 initially, you'll see that next time you start setcpu, the max and min are both at 1500. I used another app like cpu monitor widget to see what was happening and low and behold the cpu was scaling 'properly', so I left the setting in setcpu at 1500 and 1500.
In the end...it doesn't work quite the way it was designed for and even with custom kernels we're seeing some issues with it, but mess with it, you may find that enabling the 2nd core will produce less laggy games. You'll have to judge the affect on battery.

I appreciate the help! [Thanked]
Hello. I have been running CyanogenMod 10.1-10.2 since I got my device back in July, everything has been working great. Bugfixes have been lovely and all that good stuff; however one thing continues to annoy me. I cannot underclock my device properly. Let's say I go into the normal CyanogenMod Performance settings. Then I put my CPU to something like 1024MHz, then I see how the results went over with PerfMon from Chainfire, it will underclock only on Core 0, the rest of the cores still run up to the standard limit, 1890MHz. The only way I can somewhat successfully underclock is by setting my CPU to 594MHz or lower, at which point it will disable all cores except Core 0.
This has been annoying me for a while, I am running the standard CyanogenMod kernel, and recently I tried the Elite Kernel. The only thing the Elite Kernel did was remove the ability to disable the other 3 cores when below 594MHz. (And add the ability to go up to 2.2GHz, but who wants to overclock the Galaxy S4 yet?)
It may be worth mentioning if I try to tweak individual core settings with Tasker, on Core 0 it will let me set a CPU frequency, then if I go in and try to set something on Core 1, it won't have any of the default values for anything, and I enter them manually, then it will give me some errors about not finding the governor I said and stuff like that.
Anyone who knows any way to fix this (Custom kernels, different ROMs (Only for curiosity, I would stick to CyanogenMod anyway), etc) would be greatly appreciated.
Anyone who questions my motives for underclocking, question away. I don't like how my battery life is next to junk when I'm not even touching my phone all day, and the GS4 hardly needs the CPU it has, so I plan to use Tasker to set up a bunch of power saving mechanisms.
I suppose I do have one other question. Will underclocking even benefit me if I can't modify the voltage settings? Are they modified automatically when you're running at lower frequencies? (You would hope so, considering it's kinda a mobile device with a power source that isn't infinite). But if it won't help me without lowering my voltage (and if it isn't modified automatically) is there any good way to do that with a Tasker based setup, so it can be switched instantly whenever I do something? For example, launching a music player. All 4 cores shoot up to 1890MHz (I know they eventually settle down to lower frequencies, but for example's sake), I would rather have it so when I launched the app, Tasker would come in and set my CPU to ~800MHz with only a single core. Everything might slightly lag, but it would work and I would potentially get better battery life while listening to music.
Also, I never tested this on TouchWiz, as I didn't stay on it for more than 30 minutes after I got my device.
I am running the latest CyanogenMod nightly in case it matters (20131002, and it'll be 20131003 tomorrow unless it breaks something)
Thanks in advance to anyone who can possibly help with this. I'm sorry if the post is unorganized, but I hope it's understandable.
[bump]
Forgive me for my ignorance since I'm on ME7 and unable to flash CM10.x yet, but couldn't you just try different governors instead? On my old phone I was using lulzactive and it gave me great battery life, and you could tweak all the values any way you want for more performance or battery life.
I also remember when I experimented with undervolting and much to my dismay it turns out it made my battery life WORSE because of all the error correcting it was doing.
I get at least a days worth of moderate/heavy use on mine and with how fast it charges I don't really care about battery life but I'm curious how much actual gain you'll get for your efforts
