Develop Bugs

Is this dangerous...

Just installed netarchy 4.1.9 over BS 1.8, and it could be under clocked o 125Mhz. Is it safe to have the Processor work at that speed when screen is off and the min value in setCPU.
Don't want to mess the love of my life.

Thread moved to Q&A.

first this is definatly the wrong forum for this. it should be in the Q&A area.
Development is a forum where developers can post there works and isnt intended for people to ask general questions. If you have a question on something someone developed and posted in the development forum it should be in that "projects" thread.
second. If you use the search you can find a TON of information on SetCPU profiles and what is ok and not and normally it is expected that you search some yourself before posting not only to help keep the forum clean but also its hard to expect others to keep answering the same questions for people who cant even be bothered to try and help themselves first. (think of XDA as a library of information)
Now to answer your questin.
yes it is safe, i will say however that the performance is very poor and most do nto like having it clocked that low because of this. most stick to 256 or above while the screen is off so that start up doesnt lag as baddly.

You can try, my phone doesn't like to be clocked that low and reboots, mine also doesn't like 1.267 and reboots. I usually don't overclock and I only underclock to 245.

My phone also dislikes being clocked that low and will lag considerably bad when trying to wake up, sometimes only recovering after changing the clock up to 256 and rebooting. Also I clock at 1.19 as my phone reboots itself above 1.2. Seems to be a common pattern if you look around I would follow that.

I remember reading somewhere that the voltage for 128 and 256 is the same, so there is really no point in clocking it that low. Basically, it takes the same battery to run at 128 as 256, and 128 seems to cause problems anyways.

128MHz is fine on my phone with the screen off, with absolutely no lag turning it on.

[Q] Undervolt for better battery performance

I was reading around some threads and i came to see that someone created a Kernel for the Sammy GSII where they could undervolt the ram, lcd, and cpu. Just asking if it could probably be possible for some Devs so take a look at that since our display makes a huge dent on battery life..
Here is what they listed as changes:
"add frequencies -> 1.4GHz, 1.2GHz, 600MHz
Voodoo Sound Version 8 (thanks to supercurio & richardtrip)
update ext4 (thanks to richardtrip)
under voltage -> RAM(1.8v to 1.6v) and LCD(3.3v to 2.4v)"

clik HO!NO!'s kernel palace thread

HO!NO!'s kernals only UV the CPU. He's talking about the ram and screen as well.
Edit: My buddy's HOX had 77% left after 8 hours of moderate usage. Made me very jealous..

i understood fully what he was talking about.
and my comment still stands, if he is interested in what he wants, he should ckick the ****ing kernel palace thread.
jesus ****ng christ.

Dude relax lol..
He should make a thread here as he is questioning all the devs, not just HONO.

i am relaxed.
peeps that run around *correcting* others based on wrongly ASSUmming they know better will always get a reply in kind from me. you got that.
and i didn't say move the thread, the thread here is fine and the thread is fine in general, i never suggest otherwise. i said my comment to click the HO!NO! kernel palace thread is on point to the topic, as opposed to your comments correcting others and being jealous of other people's smart phones, neither of which have anythiing to do with the topic.

Kernel Questions...

Hey all, I am running KT747 Kernel on Liquid Smooth ROM. I just have a few questions about kernels and tweaking them (and yes I do know about THIS thread, but it is very cluttered)...
1. What is over-clocking/under-clocking and what does it do? Also, how do I do it?
2. What is Governor and I/O scheduler and what do they do? Also what are the differences betwteen all of the Governors and I/O Schedulers?
3. How do I tweak my kernel to get a really good benchmark score?
4. What are the voltages?
If you can answer any of these questions I'd greatly appreciate it. Thanks to all!

If you read the OP of the Team Kernelizer's thread it'll answer most of the questions.
1. over-clocking/under-clocking refers to adjusting the speeds which your processor is allowed perform at. Over-clocking means that you can set it as a higher speed and under clocking is that you can set it at a lower speed.
2. There are many different threads on what each of the govenors and schedulers do. In the OP of ktoonsez's kernel thread there are links which give pretty good explainations as to what each of them do.
3. Tweaking your kernel is going to be something that is pretty much dependent on your phone and finding the proper pairing for your phone of frequencies, govenor, and voltages for each individual frequency step.
4. The voltage settings are how much power the processor is allowed to pull while it's at each individual frequency step. These can be changed to optimize performance as well as increase battery life. undervolting too much though could result in issues with your phone.
All of this is very much trial and error.
In order to change any of the kernel settings, use the ktweaker app that was installed on your phone when you installed the Ktoonsez kernel. The app should be in your app drawer.

Thank you! I already know about the Ktweaker app as I've used it already because I followed the steps in the thread and tweaked my kernel already for the "good battery+performance" setting. Although not gonna lie, I did not know what I was tweaking lol. I do notice amazing battery life though... after those tweaks I got 60hrs with 3 1/2 hrs of on screen time (4200mAh extended battery). I just wanted to clarify what I was doing. Plus I always hear about over-clocking/under-clocking but I don't know what it is or how to do it.

Over/under clocking and under volting are explained/described pretty well in the OP of the team kernelizer's thread. That being said that sounds like some pretty great battery life.

Ever since I did those tweks I've been averaging 2 Days 12 hrs (60hrs total) per charge.... freakn awesome!

Thanks for the info, answered my question as well =p

Theres a ton of good links in the following thread too

As for CPU governors and stuff, you want the "setcpu guide on how to use" and "android governors explained" links

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?

CPU throttling at wrong temperature

After looking through the thermal file for the 5x which was posted by an XDA member. I found that the big cores are supposed to throttle at 39°c.
I don't know if this is cpu temperature or battery temperature but assuming it was battery temperature I stared running geekbench a couple of times and found that the big cores started throttling at battery temperature of 36°c. I would like to know why this is because it seems to me like the big cores throttle too early.
Is there something wrong with the temperature sensors in my device?

Can anybody help?

Your best bet would be to post this question where you got such file so the developer/creator can help you.
Theres no guarantee he/she will see this question here.
I assume you used this thread?

Also bumping of threads is frowned upon by the rules especially within a 24hr gap.
