[Q] SetCPU - Extra Info?

Hi there, thinking about getting SetCPU - I have some questions before I do because I hear it can be dangerous?
- I've heard it can brick your phone?
- What if you set it too high?
- Do you personally have to monitor it?
- What are the benefits?
- Use alot of battery?
- Is it really worth using?
- Is it optimized for different phones - example the One X?
Thanks guys!

Hi, i have read that SetCPU cannot view all the cores i have read alot saying that System Tuner works fine you might want to try that.
I used to use SetCPU on my sensation and never hand any issues with it i did not monitor the app at all
Benefits allows overclocking if available in kernel
it can be overclocked and cause some issues such as overheating but if set correctly will be fine doesnt use much battery if any
and no i dont think you can brick your phone
if you set it too high i believe i had to reflash rom nothing major
BTW this is based on my own knowledge and usage
Hope this helps

Thanks man

How much battery life can you save using setCPU?

None in theory, if the CPU is slower it takes longer to go from
idle - process - idle
Faster speeds allow it to get it over and done with faster and get back to idle.
Of course it will at times stop the CPU going higher than it needs too which could save battery.
Under volting will save more batter then underclocking ever will.

Use System Tuner and its free

Thanks. I have system tuner, but what do I need to do in order to improve battery life?
I have set the governor to powersave. Is there anything else? How would I undervolt using this app?

undervolting requires your phones kernel to support it, currently on these forums there is only one that does but i haven't tested it, sticking firm to the "stock kernel is best" and will do untill the kernels have more time to mature.
you could limit your max speed to 1 GHz, if you are rooted you can use Core control to turn off cores and run your phone as a dual core.

Not to be lazy, but would running the phone as dual core and limiting it to 1 ghz result in a perceptible battery savings? I'm trying to get a feel for how much I should expect custom ROMs to make my One X perform up to par. Thus far, I've installed two custom ROMs and felt like the improvements were all safely in the minor category.
I did install cyanogenmod 7 on a phone last year wow, that resulted in major benefits.

Running on 2 cores stops the phone from using and 2 cores uses less power then 4, playing games and using all cores is over kill 2 cores will run the game without lag use less power and make less heat.
You'll maybe get 10% from doing that but I haven't tested.
Really the only time any of this saves battery is during demanding programs, tegrea has a super low power companion core, for all your power saving needs.

I tried conservative governor while downloading sd files for Nova3 gave execllent results
I strongly advice not to undervolt tegra3
t3 is not like any other chip and UV or OC should not be attempted
OC because the chip is already at the max of its thermals
UV for the same reason n might end up with problems like flicker
changing governors and UC should be enough

Downclocking to save battery live?

Hi,
I am running a wicked v2 rom, had an idea yesterday to try to downclock cpu to potentially increase battery live. Used SetCpu, set ut to ~1.4ghz, governor is powersave. No performace hit that i can notice, outside benchmarks. On my first day now, will see how it works out. Anyone done that, any statistics?

ive been doing this since the first custom kernel was released. you get a few more hours depending on how much you downclock

downclocking always worked on my nexus 4
On a side note doesn't the powersafe governer set your phones cpu to the lowest clock speed at ALL times. As in if your minimum clock speed is 300mhz then its going to set your phone there forever?

just curious why you would buy a phone with 4 cores clocked at 1.9 ghz and dropping it???
thats like buying a 500 horsepower car, and detuning it minus 200 hp... whats the point?? Im not cracking a joke, its a serious question

Well, the plan is to get a zerolemon battery when it comes out. And i really cant see and performance hit, otherwise i would not really sacrifice... Assuming performance doesnt suffer, why not squeeze some battery life out and run a phone cooler?

Undervolting Settings

I just picked up my Nexus 7, and I have tinykernel installed, and I am now using trickstermod to undervolt my device. I would really appreciate it if someone could screenshot their undervolted settings just so I have something (like a benchmark) to go off of, along with an estimate of how much battery life I stand to gain by doing this. Thank you very much for any help!

I would really like this too!

Here are the settings I am running my Nexus on. They arent maxed out, I may get some millivolts here or there but its is at least stable. My GPU is running on -150mv
One thing to note is that I have an ACPU BIN 6 CPU.

Thanks, will try to give it a go when i have the time.
Did you notice your battery life improved vastly or were the results only marginal?
What do you mean? You mean you have a better binned cpu? How can i see my binning?
These are the stock voltages btw if anyone cares:

[Q] Anybody overclock or underclock CPU?

So i have a rooted my lg g pad and was thinking about using an app such as tegrak overclock to change the cpu frequency. I would like to know if somebody that has tested this can confirm it is safe and state the minimum and maximum safe frequenies. If you would like to know my motives, i would like my tablet to lag a little less in the higher of bloons tower defense 5 and some other games. I would also like to be able to underclock to improve battery life.

I don't have a G Pad yet but you'll want a custom kernel with modified frequency and voltage table before you overclock, otherwise your device will freeze.
If you want better performance, your RAM is more important. Use titanium back up to remove any bloatware or go with CM11.
I keep my device underclocked by 50% to prolong battery and get no problems with games.

I just bought my G Pad yesterday and the first thing I did was root it and then install Titanium backup and Greenify, those two apps do wonders to battery life and lag. As for overclock it is as you say we would have to wait for some custom kernel that allows it but from my understanding it is the Gpu and not the Cpu which is the bottleneck.
So yeah for underclocking and to fix some lag you should install Titanium backup and Greenify but be careful on what you uninstall in TB because you don't want to remove some things like for me the Knock-on feature is probably the best thing ever
For refernece, I have my Z1 clocked at 0.2Ghz to 1.2Ghz(from 2.2Ghz) all the time unless I am playing a game where I have different "setCpu profiles" for different games, setting the governor as "interactive" or "ondemand" usually makes my Z1 sit at 0.2Ghz when it is in idle-mode.

A couple of people have mentioned Greenify. I'm using Battery Doctor on my phone and it seems to do a good job. Is there any reason to choose Greenify over Battery Doctor?

It does what I want and seeing as both my Z1 and my G Pad have some good battery saving eatures I don't see the point in using extensive apps. Usually I just want one app which does what I want and Greenify does that in a perfect way.
Haven't used battery doctor myself but my guess would be that it is equally as good as Greenify

I've checked mine and it seems fine. Android is set as last resort.

it lags? mine is superfast and it's not without 2-3 dozens of apps. i've even underclocked the cpu to run at 1.5ghz, it's very fast anyway. and using its default energy saving + greenify + underclocked cpu i have a better battery too.

I've had my G Pad for a month now and no problems running at 1.1GHz. Great battery life, too

Only rooted or on custom kernel?
I want also run setcpu for underclocking and i ask before rooting.
i only rooting my gpad for setcpu underclock but don't want custom kernels.

you are on stock rooted? what apps do you use for underclock?
i'm on stock rooted and tryed various apps but underclock don't work... only cpu0 seems to underclock and for a small amount of time.
i use PERFMON

[Q] CPU Temperature exceeding 80°C! How dangerous?

Hi guys,
I understand that some heat when running resource intensive applications and games is to be expected but I believe I've passed into the danger zone, so to speak. When playing XCOM my CPU temperature quickly exceeds 80°C. From my googling on the matter I have come to assume that a temperature as high as 80°C is dangerous for the hardware of the device, but I have had trouble finding upper threshold limits for the model itself.
I guess my questions are as follows:
1) How damaging would running the CPU at 80°C for an extended duration (1hr +) be?
2) What would you consider the max acceptable CPU temperature to be?
3) Assuming it is as bad as thought, what are my options to reduce the CPU temperature, short of avoiding the problem applications? Underclocking seems to be a common suggestion, but I get the feeling that XCOM, or similarly taxing applications, may just fail to run or become incredible sluggish under such constraints.
My device is rooted and running Lean Kernel v2.4 along with the w03Slim ROM. Found here: http://forum.xda-developers.com/showthread.php?t=2638116
I've done similar test runs in the Temasek kernel with the recommended configurations through Trickster Mod and there is no difference, the CPU still exceeds 80°C when playing XCOM. After a week or so of googling, searching the forums, and digging through device manuals I feel like I'm spinning my wheels.
Any insight or advice you all might have is greatly appreciated.

Solved!

Does not exceeds to 80c now?

You can try a custom kernel, i would recommend you BioShock kernel, with conservativex, max freq 2.2 ghz and undervolt 25 mV... No more over warming for me, great performance and battery life

Agree with this post, conservativex is a great governor to keep your cpu in check and not over throttle itself, also check out my thread I made here awhile back and apply the 8th post down. It really helped keep the temp down on my phone when playing graphically intensive games like dead trigger 2,riptide gp2 etc. Also if you have trickster mod or faux clock(really recommended) you can scale down your max frequency, that should really help keep it cooler and you won't see much of a performance drop (if any) while gaming or heavily using your phone.
