[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.

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

[Q] how to bypass charger amperage limitation by Kernel?

Dear experts!
I have an Xpera S. Recently I found that some kernels (specially stock kernels) limit input amperage while charging to 1000mAh (as I explained here: http://forum.xda-developers.com/showpost.php?p=40172449&postcount=38 )
How can I bypass this limitation if I wanna use an specific kernel which has limited the amperage?
Thanks a lot in advance

it's not true with stock kernels. even most custom kernels dont have that amperage limit.
i have xperia s and ep850. i get the amperage input under 1000mA because the phone use some of em, and (maybe) bad electricity in my home. to get more than 1000mA (the max is about 1200mA with ep850), i usually turned off the data, and set it to 2G only. and if it still wont show more than 1000 mA (i use android tuner to check the amperage), i plug & re-plug the charger. but still, the kernel can accept more than 1000 mA.

The limitation is related to the temperature.
I don't remember the right value, but more is the temperature and less is the intensity "A" , "mA" .

Thanks for your attention.
You know my operator only support 2G network right now and I always turn data off!
You are right! XS stock kernel does not have this limitation! I use custom Kernel (Advanced custom Kernel v17). For me this one is better for some reasons...! But there is an amperage limitation while having this kernel installed on my phone! Besides, my friend have Xperia SL with stick kenel and he also suffers this limitation!
The question is " Is there any solution or sth to bypass this limitation in kernels that have it?"

if u encountered such kernels with limitations (from my experience, the (very) early version of Nova kernel (cm10 kernel) kinda has this limitation, but later versions dont have it), there's nothing you can do except changing your kernel. i've used advanced custom kernel (not the latest though, as i've re-locked my bootloader) and i dont think that it has this limitation, eg: charging went very fast (1200 mA with ep850). so i guess maybe change your kernel (though i doubt the newer version of that kernel has the limitation )
i think what Forzaferrarileo mean is you shouldnt charge your phone when the phone's temperature is hot, as it'll only accept lower current.

Will there eventually be kernels available?

I have the tab pro 8.4, are kernels currently in development? What are you guys using to overclock?

Not now.
Crpalmer is working on a kernel and if he releases that then I think we could expect one for custom roms.
And this tablet doesn't need overclock. Nor will it handle it. The only thing that would be helpful is voltage control. it gets hot enough as it is.
If you really want a performance boost root it and change the cpu governer to performance. It locks the cpu at 2. 3 ghz. (the tablet will get insanely hot though)

Xthermal Mod - Fast Charging + CPU + GPU Tweaks

Original thread for Nexus 6P is located here:
http://forum.xda-developers.com/nex...t/xthermal-mod-fast-charging-cpu-gpu-t3433784
Hi Guys,
After a very successful journey from Redmi 1s to Nexus 6P, I'm now here with my Xthermal Mod for Mi 5.
I'm personally testing the mod since a week and will be rolling out all the profiles soon.
Till then I need your help to test it out in different conditions.
Please join and help me to make it more better this time.
I'm attaching Fast Charge only profile as of now.
Edit: Xthermal Performance + Back to stock added...

1. Stock charger supports max 2000 mah.
2. Max Charging current is controlled by the Kernel itself.
As soon as battery level increases the charging current goes down.
You might have observed that if battery level is below 50% then charging is super fast but after 60% it is very slow.
If you (your apps) do not use the handset resources much while charging then you do not need this mod.
If you use your handset while charging (which is strongly not recommended) example for gaming, browsing or chatting etc then the temperature rises slowly slowly.
The stock limits are very aggressive and it starts throttling and your cpu, gpu and charging speeds goes down.
So this mod comes into play here and delays the throttling a bit resulting in better cpu, gpu and charging results.
Does it produces more heat?
Heat is directly related with performance. This mod itself doesn't produce any heat but yes delaying the throttling means the handset is able to use all your resources even if temps rises hence may result in a bit more heat + more performance.
The results are more amazing if you have a fast charger.
I believe there is no risk in flashing this but still don't blame me for all your actions.

Is there any requirements? Miui? Cm? Kernel?

Please upload the "back to stock" for mi 5. Thanks

I don't see "thermal-engine-8996.conf" file in my rom. Assume I can just delete the file (or re-install rom) to revert to default.
By the way, do you know what's default value for each before this mod? Hope this mod not increase the threshold too much. Worry it will boom.
I've read original thread, what I understand is our phone will charge faster but trade off with hotter while charging.

No need to flash both as fast charge is there in performance zip too...

Just flash performance zip.on miui 8 6.9.29 i feel the phone faster then before,fast charging work good,just for test from 20%to100% 50min.Good joob

Just flashed it too. Phone seems much faster will see about charging and battery drainage but I prefer faster phone over battery always

Would you mind explaining technically what those mods do? e.g.: governor, upper and lower frequency limit, etc. Some of us like to know the geeky details

Can I over clock CPU?

What I have to do to over clock my CPU from 1.8 Gz to 2.2Gz I'm on bootleggers unofficial ROM , any one who knows ?

Flash a kernel that supports overclocking. Then use an app of your choice to set the max frequency.
I assume you know the risk.

Faster as opposite to what..like 2 years vs 5 years? Haha!
Max thermals reach 46-48 which is only 2 or 3 degrees higher than stock & the temps/cpu clock anyway get limited by the thermal engine automatically after that.

It depends. If you do a full overclock you can risk killing your motherboard faster.
Slightly overclocks don't affect with nothing if the cpu temperature increases with 1-4°c.
Still, getting better cooling on your phone is a much better choice. Changing the thermal paste etc etc.

This is irrelevant to the op's request/question.
I dunno why a simple question thread couldn't be followed up by discussion of simple answers?
Look, It doesn't matter even if it destroys the phone cuz that's not the point of the thread but if you were insisting to be pedantic then that still could have been added in the end but only if you'd chosen to atleast answer something relevant at first = being relevant.
Ultimately these types of posts/replies are no different than spamming say a redmi forum with lenovo or iphone related questions..
Regardless of the above, oc on current kernels is not dangerous as such because there is no alteration/upping of voltages manually.
*** There is also a fixed "setpoint" of temperatures, frequencies,voltages etc in the inbuilt thermal engine profiles which no simple oc of frequencies is going to get past through unless one decides to disable it manually . If the temperatures reach even the lowest thresholds of preconfigured "high" levels then the chipset will start to downclock at once in fixed steppings***
