Can anyone post the lowest CPU speed they ever set and with their lowest voltage for that minimum speed they used (still being stable)?

So far I tried 189 Mhz with 875 mV (for both 189 and 378) and wheatley governor. Seems stable so far.

I don't want to go too low as it gets a tiny bit laggy the first 2 seconds when I use it.

Speed wise, it falls 27% on 378 MHz most of the time, 8% on 189, and the rest is mostly on Deep sleep.

Just wonder how low people went.

This kernel has great performance and battery life, only. Issue I have this random rebooting. It only happens with this kernel. Sometimes when I press the power button to turn on the screen, the screen doesn't turn on. Stays off. And even when the phone is idle, or when I'm playing music, it just freezes. Other than that, this kernel is great.

I wanted to say thank you for this wonderful kernel!

I used the other known kernels for the i9505 but i've had bad luck with most of them when gaming...games were laggy and fps were dropping even in games where they were not supposed to drop at all (eg Jetpack Joyride, Rayman Jungle Run).

Only stock kernel could run the games fine, but i had an issue with wifi so unfortunately I couldn't keep the stock one.

After that i gave your's a go!

With your kernel, even Gangstar 4 which is a very crappy game, runs great if I set the min cpu freq to 1500mhz!

I've never played Modern Combat 4 in 60fps before! o.O

So yeah, thank you for this!

It's simple and works great.

Have a nice day man! :)

EDIT:

Btw i'm on Omega v9.0 TW Rom, using your TW kernel, if it matters. :)

UNFORTUNATELY EDIT 2:

I run into the same issue just seconds ago.

Is there anything i can do?

Could a logcat or dmesg be useful to you?
[Samsung Galaxy S 4 Unified Development] SignalX:
possible to add Wolfson or Boeffla sound mod to the kernel?

anyway, is there any sound mod hack for i9505?

thx
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
Sorry, those use the wolfson dac the S3 had.

It can't be used on i9505 because it has a texas instruments dac.

Only if you get an i9500 you can have perseus kernel which i think has these mods because the i9500 has a wolfson dac.

The i9505 has fauxsound in some kernels, but search because there's a sound boost mod here in xda for the i9505 which works on any kernel.

@albinoman887

I had two more reboots, is there anything i can do?

Thanks.
[Samsung Galaxy S 4 Unified Development] osmosizzz:
Yeah its definitely the kernel. Went from this to faux's kernel and back to this and the reboots and freezing are back. the kernel is good but it sucks when you want to pick up your phone to check anything and the screen just doesn't turn on. But when the phone is up and running, the kernel works exceptionally well
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
Yes, I agree with you. :)

I guess we'll have to wait for the dev to check what's wrong.

Also I disabled any kind of oc and uv a while ago and so far no reboots.

Is your's running oc'd or uv'd?
[Samsung Galaxy S 4 Unified Development] osmosizzz:
Yeah I over clocked but did not under volt
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
Try disabling oc and see if it'll reboot again...

Maybe our chips aren't stable enough for it. :/ (I kinda doubt it though.)
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
Does KTweaker work with this kernel?

I saw a post earlier, so i'm asking just in case.

It'd come in handy!
[Samsung Galaxy S 4 Unified Development] omniwolf:
hey [MENTION=3382081]nfsmw_gr[/MENTION], i don't mean to be a ****, but..

you've been here a while. you have over 1000 posts. So why don't you know how to search, rather than spamming every thread you take an interest in?

1) if you had searched you would have seen that I have already reported crashing on the TW kernel, and had provided logs, and albinoman had replied to it.

2) you know how kernel crashes work. You provide the dev with the last_kmsg. where is your last_kmsg? how do you expect him to fix it without logs? This is simple and I know you know it. Stop wasting our time.

3) does ktweaker work? Why not try it out and let us know, instead of spraying the thread with trivial questions about a different kernel's config tool. seriously.
[Samsung Galaxy S 4 Unified Development] lobird:
I'm sorry this question may be already ask.

how is the battery life with this kernel without overcloking?

And how is it when you overclocked the gpu to 600mhz
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
Well, the dev didn't respond to any of my questions, nor anyone else here except osmosizzz.

1)I've seen those posts, and albinoman said he needed source of the original i9505 kernel, so I didn't know whether i should provide logs or if it would be useless to provide them.

Since i'm on limited data connection i asked.

2)I don't like your attitude in this one, read no 1.

3)Sorry but i'm on limited data right now, that's why i was asking.

Anyway, you should learn to be more polite.

If you check my posts in general you'll see that most of the times I try to help.

If the dev has any issue with me I'm pretty sure he'll tell me.

If you have any issue with me, report me instead of writing useless posts.

Have a nice day.

[MENTION=4196197]Albinoman[/MENTION]

I'm sure you're aware of that but still I'd like to post it.

There are quite a few .zip files with source code for the i9505 here:

I don't know if any of those will get the job done though.

[Samsung Galaxy S 4 Unified Development] CallumMarks77:
Getting a lot of random reboots recently....

all i have done is installed the kernel and cranked up the min cpu value to 1134?

See my signature for my device and rom
[Samsung Galaxy S 4 Unified Development] codenamezero:
Why would you do that? Anyhow, was your phone over heating setting the min value so high all the time? I've been running this kernel for about two weeks now and no random reboot what so ever. Only when I change the CPU governor to something else then it would freeze and reboot.
[Samsung Galaxy S 4 Unified Development] CallumMarks77:
nope not hot or any thing just a random reboot
[Samsung Galaxy S 4 Unified Development] andyjg247:
Out of interest what was your thinking behind increasing the lowest value?
[Samsung Galaxy S 4 Unified Development] codenamezero:
Try to completely wipe your system and do a fresh install... also the random reboot, may have nothing to do with the kernel, could simply because of your custom rom. I am running P.A.C.man rom using this kernel, and it had been fine with no random reboot.
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
At least for me, it eliminated any lag my games had.

But i only crank min up when gaming. :)

Maybe he did it for the same reasons?
[Samsung Galaxy S 4 Unified Development] codenamezero:
Actually, you don't need to crank min up in gaming... it has to do with your cpu governor... ANY governor will eventually crank it all the way to max if what you are running require such high cpu. the question is how fast it will crank up... if you picked some conservative governor of course it will be slow and laggy in your game (for example if you picked conservative or something).

Bottom line is that it serve virtually no purpose to crank up the min, you are better off picking a more responsive governor.
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
I've had bad luck with governors on the S4 actually (on my S3 i didn't have to crank up min), regardless of kernel.

So this method is very efficient and only uses battery when gaming. (battery would be consumed anyway)

So, why not? :)
[Samsung Galaxy S 4 Unified Development] codenamezero:
No. That doesn't even make sense, the governor either works or it doesn't. Not sure which ROM you are using but look at the CPU statistic under the performance control panel, it shows the time it stays at the CPU cycle.

And no, the battery being consumed is not equal so is not totally true that "battery being consumed anyway"... You use less battery as your CPU rubs at lower speed. Maybe your game don't always need to runs at full speed.
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
It's fine if you don't agree with me.

If I set min 378mhz, gameloft games which are poorly written are playable but tend to lag more.

If i set min 1242mhz+ those crappy games lag way less.

Maybe they don't need that much cpu boost to be playable, but they benefit a lot from it in my experience.

Anyway, the battery is great with my phone using this gaming only profile, i've been gaming about 2-3 hours, browsing the internet and in the end of the day i still have around 25% still left. :)

Surely I may save 5-10% more if i set min 378, which won't be used anyway in games but i prefer to have a smoother gaming experience than have more battery left.

Thanks for the tips I already knew, but I choose not to use them on purpose when I play heavy games.

On lighter or better optimized (or call it whatever you wish) games i don't mess with min cpu frequency because they run fine with stock settings.
[Samsung Galaxy S 4 Unified Development] Rayfucious:
Anyone using tw version on omega v9.0 ?

Mind sharing settings and app you use to control ?
[Samsung Galaxy S 4 Unified Development] codenamezero:
What you said makes no sense unless you picked conservative/powersave governor but whatever floats your boat.

You should read up how governors actually work. Peace.
[Samsung Galaxy S 4 Unified Development] lobird:
Thanks (^.^) /
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
No problem. :)
[Samsung Galaxy S 4 Unified Development] Rayfucious:
Hi can i know what app you are using to control this kernel ? And which gov you using ?
[Samsung Galaxy S 4 Unified Development] codenamezero:
After using the kernel for over a week, fine tuned some settings and some tweak with the min, voltage, Wheatley governor. :D

14 hours. :)

Too bad the Wheatley is not configurable, I'd like it to scale the cpu stepping a little better between 50% loads and up.

CPU load statistics:

6% at max speed (2h21)

7% at 1674 Mhz (2h39)

1% at 378 Mhz (31m)

45% at 189 Mhz (16h41m)

37% deep sleep (14h)

The rest of the cpu stepping contribute to less than 1% cpu time. The hours don't add up to 14h because it was the stats of like 2 days+. but that gives you an idea of the %.
[Samsung Galaxy S 4 Unified Development] albinoman887:
OK i'm kinda getting sick of posts like this. there are 3 different kernel versions. i'm not a mind reader. i dont know what one your using.. from now on. and i will put this in the op when i get time.. if you report a bug and you dont tell me A: what rom you are on and B what kernel variant you are on. i will simply ignore your post. no reply i'll skip over the entire thing and not even read it... sorry i know this sounds harsh but i need to nip it in the bud

he does have a point here. i have this kernel for 5 diferent carrier variants. so i have seen this same post repeated about 10 times about their kernel rebooting. and they give no info what so ever. its already hard to follow 5 different threads for one project. can you guys please meet me half way with a detailed report and a last_kmsg. also please BEAR IN MIND I DONT USE TW SO ITS PROBABLY GONNA BE MORE BUGGY I WILL BE RELYING ON THE USERS FOR LOGS. I HATE TW. I'M NOT FLASHING IT lol

also jizzer rom is known to cause issues with my kernel

not that i care. but i have to agree with the other users. setting the min that high is pretty strange. the whole point of the governor is to ya know "govern" the cpu. if it needs to be ramped up. it will be. just use ondemand. its effectively the same as having it set to max all the time just saves power. these processors arent ment to be clocked that high all the time. you will most likely destory it over time. you might not not know. but your pc most likely is governing your cpu right now. if its a recent intel cpu. they have a gov or sorts. cpus are smart. they ramp up when they need to now. a static clock is kinda a thing of the past now. would you want your car to be sitting in park but the gas petal to the floor? thats basically what your doing,, wasting "gas" but in this case, power, and life of the cpu
[Samsung Galaxy S 4 Unified Development] crzykiller:
Finally someone else that uses Wheatley. IMHO it is by far the best Governor for battery life and keeps things so cool.
[Samsung Galaxy S 4 Unified Development] Rayfucious:
Hi, i am on omega rom v9.0 and using the tw kernel, i got a white screen reboot by using the default settings, i did not tweak any settings. Everything is fine except for the white screen reboot. I was wondering any apps i can use to configure and any recommended CPU govern for battery settings ?
[Samsung Galaxy S 4 Unified Development] codenamezero:
Yup, my other concern was that with other governor, it would bump the cpu all the way to max regardless of what you do (pretty much). That cause my phone to heat up incredibly fast. With the tuned down voltage and Wheatley, my phone stays in a reasonable temperature now when doing normal tasks such as checking facebook and browsing while streaming online music with bluetooth. good thing is that, it still able to kept the cpu reasonably low without lagging (hence you see my cycle stayed around 189-378 a lot).

Only when I play games it would gradually bump it towards the max, although as i state before, i wish it scale up a bit slower between 50-100% tho.
[Samsung Galaxy S 4 Unified Development] Rayfucious:
Any help here ?
[Samsung Galaxy S 4 Unified Development] nfsmw_gr:
Okay then, if it reboots again i'll just post without further delay.

I mentioned in my previous posts i was on your TW kernel and Omega Rom v9, so i provided all the info I could without wasting mobile data. (sorry, i'm changing ISP and have no connection at this time)

I was on limited data connection where data costs a little bit too much at least here in Greece, I mentioned it before too so I couldn't "waste" data that's why i was asking if you absolutely need these logs!

(how can he be right if I said I don't have data to spare?That was the only reason i asked.

Anyway unfortunately, I made a mobile data contract for now until my ISP is changes so now I have data.)

On the second part ondemand is the governor I use.

But my S4 is acting strange from times to times, sometimes it's smooth, sometimes it's not (I'm talking about gaming only) so if i see it lag a bit, I enable the gaming profile which cranks the min up a bit.

Maybe it's because gameloft games are poorly written?

Maybe.

But still, cranking the min a little bit reduces a lot of the frame drops, stutter, lag etc. (at least for me)

Geez, is that so bad?

I've read this guide http://xdaforums.com/showthread.php?t=1369817 which I've bookmarked and one or two more when I was google searching but didn't bookmark those since this guide seemed better.

I know how governors work, I've been rooting, flashing and in general toying around with android devices since the original Galaxy S.

So thank you for the suggestions, but sometimes only in gaming I really don't care if i waste a little more battery than normal so i can play smoothly. :)

---------- Post added at 02:48 PM ---------- Previous post was at 02:47 PM ----------

I use the chronic config script which is in /system/etc directory, plus setcpu.

Also i use ondemand governor.

also theres no update to the tw version because all i changed was upstream changes for the 4.3 kernel. nothing else. those changes dont apply to touchwiz of 4.2 so those dont need an update. thats why its 2.01 version numbers go like this

example vA.BC

A = major update, either a rewrite, new stable tag or lots of notable new features

b = incremental. smaller updates, bug fixes. smaller tweaks. no big additions

c = matience updates. mainly upstream updates to keep compatibility with latest roms

how that clears it up
