Can you do an antutu bech test with these settings and post them here?? I know is not important in real life but hey i just want to know how it goes haha!!!
[AT&T Samsung Galaxy S 4 Original Android Developme] :
Haha. And you guys think you have good battery? :p also running at 2.1 ghz
[AT&T Samsung Galaxy S 4 Original Android Developme] Hippoman13:
I've literally gotten 10 Hours of YouTube playback before (that's what happens when you're sick at home with nothing to do)

and also 6 Hours of gaming :P (separate occasion)
[AT&T Samsung Galaxy S 4 Original Android Developme] Edu616:
Awesome battery !!!!
[AT&T Samsung Galaxy S 4 Original Android Developme] :
Going to bed. If you want my kernel settings let me know. Also not plugging this baby in haha let's see if it lasts the night.
[AT&T Samsung Galaxy S 4 Original Android Developme] MikeC4510:
Just running Ktoonsez's settings... Could have easily gotten up to 4 hours of on screen time but I didn't want it dying on me :p. This would have been better had I not been running on low signal at work (I believe I was on 2G for the first time :confused:)

WiFi issues after flashing

First and foremost, I'd like to appreciate all your dedication to the Android community. You've always done excellent work. I am having some issues since my most recent flash. I came from the May 23rd build, and all was working perfectly but since I re-flashed to the most current build, my WiFi does not want to connect. i wiped cache's and fix permissions, but still a no-go. I am on complete stock TW rom @ the moment as well. I am running TWRP as my recovery. Thanks for everyone here!
[AT&T Samsung Galaxy S 4 Original Android Developme] family682guy:
I've been having nothing but bad luck with this kernel... Since flashing, I've had constant force closes, bad battery life, and for some reason my device doesn't like charging anymore. It does charge, but just VERY slowly..
[AT&T Samsung Galaxy S 4 Original Android Developme] Mushroom.:
I'm unclear, does this work with cm10 yet?
[AT&T Samsung Galaxy S 4 Original Android Developme] DJsCrIBbLe:
What is your install procedure and what ROM are you using with. Do you have a log cat or dmesg to provide ? If not your post does no good....you have to provide developers with info vs complaining ...
[AT&T Samsung Galaxy S 4 Original Android Developme] david.degraw54:
You mean CM10.1? If so, yes it does. There are separate versions for TouchWiz and CM in the OP.
[AT&T Samsung Galaxy S 4 Original Android Developme] Mushroom.:
I knew that; at one point, the AOSP version of this kernel bootlooped on CM10 but worked fine on AOKP, so I wasn't sure.
[AT&T Samsung Galaxy S 4 Original Android Developme] family682guy:
Alright, here's my installation procedure:

1. boot into TWRP

2. flash kernel

3. wipe cache and dalvik

4. fix permissions

My ROM:

Stock TW 4.2.2

(the same the it shipped with)

I've also attached the logcat, as per your request
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
No errors in there at all so not sure what the issue could be. I would just wait to try the next version. Some phone just dont like custom kernels since all phones are so different, ran into this many many times on the S2 and S3.
[AT&T Samsung Galaxy S 4 Original Android Developme] family682guy:
I actually had problems with the ktoons kernel on my s3 as well... maybe it's just me? :'[
[AT&T Samsung Galaxy S 4 Original Android Developme] stevehkim:
What Gov/Sched are you using? Does this happen on any other custom kernels? Maybe try adjusting the GPU oc back down to 450 mhz. That option isn't listed in KT app so use trickster mod or something similar.
[AT&T Samsung Galaxy S 4 Original Android Developme] david.degraw54:
Oh well yeah ktoonsez fixed that some pages back but the new 5/27 version works fine.
[AT&T Samsung Galaxy S 4 Original Android Developme] family682guy:
I actually haven't gotten around to flashing another kernel yet, I've been busy at work and in my free time I've been trying to get this kernel to work. I'm using the interactive gov with the deadline sched. I've been playng around with them though and the problems have been consistant with all my configurations.

If you could, PM me a good setup to use with this kernel and I'll try it and see what happens. I've also been thinking about flashing another ROM, but I havent decided on one yet.. Like I said, work keeps me busy :P
[AT&T Samsung Galaxy S 4 Original Android Developme] DJsCrIBbLe:
Use the settings from post 3 and then maybe try to use voltage control or some other app to lower GPU clock back down to say 450 and see how that is.. you can try without setting the GPU back to 450 first and see how it is.
[AT&T Samsung Galaxy S 4 Original Android Developme] jgruberman:
I'm not asking this for the purpose of trolling, but a legitimate question because I just don't know the answer..... but how does this differ than the Faux kernel? Obviously, my biggest concern is battery life so I'm curious what factors into that.
[AT&T Samsung Galaxy S 4 Original Android Developme] Ambush510:
Just had a quick question. The KTweaker somehow does not stay running in the background memory. Why is that? I want it to run in the background so it can do what I have set up in the settings for it do. Any advice would be great.
[AT&T Samsung Galaxy S 4 Original Android Developme] alacrify:
It's a settings app - you don't want it to run in the background. You want it to set the thresholds, flip the switches, and then exit once it's done so it doesn't eat memory or clock cycles. That's what it does - and that's a good thing ;)
[AT&T Samsung Galaxy S 4 Original Android Developme] Ambush510:
If its a settings app then why is it when I run the quadrant app the score is higher with the settings app running in the background. When the settings app is not running in the background the score is lower.
[AT&T Samsung Galaxy S 4 Original Android Developme] kasper67:
I do not run this kernel, not yet anyway. But I do run ktoonz kernel on my nexus 10. Once the settings are applied on boot that's all you need to do. You will not see it as a running process in the background.

[AT&T Samsung Galaxy S 4 Original Android Developme] Ambush510:
Actually never mind I am getting the same score in the benchmark :D Thanks for the quick reply though.
[AT&T Samsung Galaxy S 4 Original Android Developme] Edu616:
I would love your settings please pm me or something with those settings!!! thanks in advance!!
[AT&T Samsung Galaxy S 4 Original Android Developme] :
Woke up on 5% ! haha.

Anyways

Enable OC steps in general
Set Min to 189 and max to 2106.

I/O Scheduler is Row
Cpu Governor is Intellidemand,

Go into Governor adjustments in General,

Boostfreq: 1

Up_threshold: 85

Up_threshold_any_cpu_load: 85

Up_threshold_multi_core: 85

Go back and hit Voltages and then menu and subract 50mv total so subract 25 twice.

Go back again and hit Extras:

Screen off profile mhz: 486
Screen off profile scheduler: noop

Done!
[AT&T Samsung Galaxy S 4 Original Android Developme] XGhozt:
After I flashed this I had to re-root my device, is that normal?
[AT&T Samsung Galaxy S 4 Original Android Developme] Ambush510:
That is normal.
[AT&T Samsung Galaxy S 4 Original Android Developme] BuBbLeFIZzY:
Antutu benchmark crashes when I undervolt -50. it runs fine when I put it back to stock. Just a heads up if your having fc problems(might not be the cause for all phones).

I installed the TW version on a TouchWiz rom and I noticed the top of the back of the phone heats up quite a bit during charging. Is this normal or something I should be concerned about?
[AT&T Samsung Galaxy S 4 Original Android Developme] Jonnyredcorn:
So I remember asking the question regarding lower steps and voltages that if steps 81-702 are all running at 900mV(stock[or -50mV your settings) wouldn't it use just as much battery power using your min mHz as 702mHz as it would at any step lower than that? I remember when I asked the same question in your gs3 thread you responded yes to steps running at the same voltage using the same amount of power, however since I see you have your min set at 184mhz and not 702mhz and you have UV'd -50 across the board that may not be true for this device seeing as it's a quad core CPU?

I guess my question is that since 81mhz-702mhz all are set at the same voltage(stock & w/ your settings UV'd -50mV) wouldn't power use benefit from lowering the voltages on the low end steps or performance benefit from running 702mhz as min?

I apologize if my question is dumb just something I noticed while playing around with ktweaker.

Thanks for bringing your kernel to the gs4...just got mine in the mail a few hours ago and after being on the fence of getting one since it was announced I'm very happy with it...the screen alone was worth the $150 I paid for it (AT&T has great customer care, if you've had bad experiences with them you just don't know how to talk to them :), I've upgraded my line 3 times in the past year and never paid the full regular upgrade price) I'm very interested in seeing how battery performs.

[AT&T Samsung Galaxy S 4 Original Android Developme] spectrumfox:
Thanks for the update! I will install it now. Any thoughts on the heating issue I posted about?

http://xdaforums.com/showpost.php?p=42031693&postcount=474
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
No problem, phones get hot sometimes especially with Touchjizz ROMs, really has nothing to do with the kernel, its all about what your ROM is doing in the background/foreground
[AT&T Samsung Galaxy S 4 Original Android Developme] spectrumfox:
Well, to elaborate a bit more on the story, I was originally running Task's AOKP with your AOSP kernel and the phone was heating up when charging. Earlier today I decided to try another ROM so I went with one of the slimmed-down Touchjizz ROMs using your TW kernel and I'm seeing the same thing.

Hense why I'm wondering if its a problem with the phone or something in your kernels causing the overheating and you might want to know about it. Last thing I want is for the damn thing to explode sometime at night while I'm sleeping. ;D
[AT&T Samsung Galaxy S 4 Original Android Developme] Hippoman13:
Hey, thank you for this amazing kernel. I have two questions:

1) Will the GPU overclock greatly effect battery life? At about a 10% overclock, it shouldn't make a huge difference; however, I am not aware of how often Android ramps the GPU to max frequency.

2) Would FIOPS, BFQ, or ROW be the best scheduler for performance with this kernel? I constantly get varying performance when I test all three.

Thanks again!
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
Heat is too subjective I guess is what I really need to say. What feel warm to one person might not to another. Mine feels perfectly normal with A/C or usb charging. I guess you gotta decide if you think its too hot. We are over 2000 user now so I would say you are safe :good:
[AT&T Samsung Galaxy S 4 Original Android Developme] spectrumfox:
Good enough for me. Thanks, man. You rule.
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
1. I dont think its gonna effect battery

2. If you want pure performance go to ZEN, if you like normal performance and normal battery use ROW.
[AT&T Samsung Galaxy S 4 Original Android Developme] mbc663:
U really have been busy kt. Thanks bro!
[AT&T Samsung Galaxy S 4 Original Android Developme] spectrumfox:
For the TW kernel, the default seems to be set to NOOP instead of BFQ like you previously said was meant for TouchWiz.

Which would you recommend? I've been reading up on both of them in general and they both seem to have advantages and disadvantages so I was wondering what your opinion is.

Also, don't use ROW for Touchwiz?
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
CFQ was default from Samsung, I recommend ROW for normal use. Use ZEN for SUPER perofrmance!!!!! :good:
[AT&T Samsung Galaxy S 4 Original Android Developme] beast3300:
Hey KT! Is it still suggested to clear ktweaker data and uninstall it before flashing the kernel?
[AT&T Samsung Galaxy S 4 Original Android Developme] :
Is there anyway to access the mDNIE settings in touchwiz?
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
No, only when I tell u in change log
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:

[AT&T Samsung Galaxy S 4 Original Android Developme] manny05:
Nice update. What settings do you run ktoonsez? In terms of screen and gpu

Sent from my Samsung Galaxy S4
[AT&T Samsung Galaxy S 4 Original Android Developme] :
I mean you added all these features, for screen control and such for gamma I'm assuming that's all aosp stuff since you can't change those settings in TJ
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
It works for both TJ and AOSP.
[AT&T Samsung Galaxy S 4 Original Android Developme] :
Any reason why battery life isn't as good as previous kernel at same exact settings
[AT&T Samsung Galaxy S 4 Original Android Developme] jiggytom:
You have to give it at least one day to break in the new kernel.

Just switched over, phone is blazing on slim now. Great work!
[AT&T Samsung Galaxy S 4 Original Android Developme] nickhimself:
In the Governor Adjustments section, wouldn't changing no_extra_cores_screen_off from 1 to 0 potentially be a better option for battery savings? Seems like allowing your phone to run multiple cores for processes would cut down on both processing time and power consumption as it would utilize multiple cores for one task rather than possibly taxing one core which would mean the phone would have to work harder and longer to accomplish something.
[AT&T Samsung Galaxy S 4 Original Android Developme] DeathAngel66669:
Thank you, ktoonsez for making my S4 even more awesome!!
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
Give it a try and let us know. I use 486 Max Mhz and no_extra_cores to 1 cus it saved me battery. I do run AOKP so only 3-4 processes running the background. It might help you if you are a Touchjizzer since you will have over 50 background processes running in the background. It will almost always depend on the ROM and ROM type :good:
[AT&T Samsung Galaxy S 4 Original Android Developme] nickhimself:
I have Slim Bean running, but the logic still seems sound. Here's a quote from a wiki entry on multi-core processing:

I'm going to run it with extra cores being allowed while the screen is off for a while and see if I notice any performance / battery benefit or loss.
[AT&T Samsung Galaxy S 4 Original Android Developme] spectrumfox:
I'm having an issue with the volume of music I play in Google Play Music using AOKP and this kernel.

Occasionally when listening to music, the volume will decrease somewhat, such as when an alert is going off. The problem is the volume will remain decreased when the event sound ends. The only way to get the volume to return to normal is to stop playback, kill the app, then start the music again.

I've tried wiping and reinstalling the recent release but the problem persists. I'm not sure if this is a problem with Google Play Music, or the Faux sound built into the kernel. Would something like this be caught by a logcat? If so, I'll post it.
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
You might be able to see something in logcat, just to be clear though all that stuff is in the ROM, kernel has zero control over that stuff, the kernel only does what the ROM tells it to do.
[AT&T Samsung Galaxy S 4 Original Android Developme] spectrumfox:
I kind of figured, except that puts me into a catch-22 situation. I can't report this to Task because I'm using your kernel and he doesn't support that, he'll just point me over here.

Do I have to deodex to use the KTweaker app?
[AT&T Samsung Galaxy S 4 Original Android Developme] Slade8525:
dumb question (WinMo5/6 and Pineapple iPhone veteran; not so knowledgeable in Android).

AT&T i337 White 16GB

NottachXposed rooted/debloated

Casual R527b/TWRP Loki'd

SIM unlocked

Stock Kernel, Stock bootloader. I want to keep TW (i'll just freeze whatever i dont use anyways) but not sure if i flash Loki'd TW ROM and then LOKI'd TW Kernel (from here) first, and when do i wipe cache/reset etc? Basically what order do i complete it all in (after i create a backup via TWRP correct?) I use the IR blaster daily and smartstay so i want to stay with TW ROM for now.

Thanks!

Haven't flashed a ROM or Kernel since the MB860 was cracked back in '10 or '11, with CM7.
[AT&T Samsung Galaxy S 4 Original Android Developme] slider2828:
I just downloaded it and it won't install. I shoved it into /system/app and it shows up but crashes when I try to launch....

Weird... I got KTweaker from http://d-h.st/V6F is that right?
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
What are you trying to do? The download from this thread is a zip file that you need to flash inside of a Custom Recovery like TWRP or CWM
[AT&T Samsung Galaxy S 4 Original Android Developme] slider2828:
Usually you have to have recovery with LOKI first. Then most rom's usually have the Loki'ed kernel in the rom itself. No need to flash twice unless you want the KT Kernel which OC/UV's...

Hope that makes sense
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
Dont know what that is but you dont want to install that.
[AT&T Samsung Galaxy S 4 Original Android Developme] slider2828:
Sorry.... KTweaker app to tweak the settings correct? I already flashed the kernel already.

Thanks in advance.
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
KTweaker is already installed when you flashed the kernel.
[AT&T Samsung Galaxy S 4 Original Android Developme] Slade8525:
i should have clarified that i have TWRP recovery LOKI'd on the phone already (the Casual R527b method). I have this GS4 underclocked already; no need to OC. GF will probably OC hers but shes running CM10 already with CWM (i think).

So basically i can backup, flash LOKI'd TW ROM, clear dalvik/reset/etc and the kernel is baked in, i should be good to go. I have no problem getting root again in the event it craps out on me (lost root twice already).

Thanks!
[AT&T Samsung Galaxy S 4 Original Android Developme] ktoonsez:
Make sure you flash my kernel after ROM then do the wipes
[AT&T Samsung Galaxy S 4 Original Android Developme] DJsCrIBbLe:
You don't even have to flash the tw ROM. I'm still running the debloated, deodexed stock DL firmware. And if already have Loki recovery just flash the kernel then wipe caches and fix permission s

Hey kt, is there anything in TJ that creates a battery drain with ktonnservativeq, like the S3? And I noticed that whichever governor I choose the extras cores still shut off even with your auto hotplugging disabled. I renamed mpdecision with no effect on cores. Is there something else shutting off the cores? Btw, the kernel rocks I was at 3 hrs screen time within 7 hours with 50% remaining so definitely awesome!
