Nothing to do with the kernel. That is all ROM.
[T-Mobile Samsung Galaxy S 4] kevinrubio1:
So basically no
[T-Mobile Samsung Galaxy S 4] ktoonsez:
You should read my response on previous page. I know you guys have to have some newer ROMs, everybody else does, even me on ATT.
[T-Mobile Samsung Galaxy S 4] mamba720027:
For the curious :)

Heres after I need to recharge with settings posted 2 page back and after the screenshot posted. Also I attached betterbatterystat usage monitor to show partial wake stats. Considering the wasted time while screen off that the device was awake due to networkloaction running in background and others I think its good but will be better after I get those background services to sleep instead of wakeing the device :)

Dude that's ****ing crazy! In trying your new settings as soon as I get home from hell I meant work

Hey kevinrubio1 just flash omega. With kt kernel it's the full stock experience with the newest firmware. There are a ton of fixes to the stock rom! Everything works perfect

My names kevinrubio1;43336365 :o?

And I would but I don't really like the dialer color, I really like the white one on my white s4 and that's what's keeping me from changing sadly :/

---------- Post added at 05:04 AM ---------- Previous post was at 05:00 AM ----------

Oh i didn't see your reply! But I might have to flash a international rom :/ could you recommend me one?

Also, do you think tmo will release all 7 updates in like one big update soon? I just really like the white dialer lol

---------- Post added at 05:06 AM ---------- Previous post was at 05:04 AM ----------

Are you running that battery guru app? I forgot what it was called but does it increase your battery by a lot or just minimal?
[T-Mobile Samsung Galaxy S 4] mamba720027:
It actually lasted longer than I expected after I was trying to scruffle in few things get done between that 1-5% before work and rechargeing :D
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Unfortunately I dont know any TW ROM's, I never use them. If all you care about is the dialer, go ask in general forum how to move the dialer from one ROM to another, its very simple just to copy the apk from one to another. I believe TMO already has a MF3 leak, could have sworn I saw someone ask on last 2 pages if MF3 works with this kernel.
[T-Mobile Samsung Galaxy S 4] kevinrubio1:
I never thought of it being that easy, I'll ask just in case! Thanks, I'm impatient when it comes to tmo and their updates!
[T-Mobile Samsung Galaxy S 4] mamba720027:
Yea im testing the battery guru app but I cant say if its doing anything much cause it suppose to learn usage pattern and adjust to save overtime but the whole thing sounds fishy cause what else is their for it to adjust that were not already doing better kernel wise and theirs no info on what it really does on the web beside preventing some apps from wake. So Im keeping and eye on it ,so far it only seem to send usage data when device is asleep :p:D

But too early to say,only about a week now im useing it.

Alright thanks :D let us know if it's worth installing! Oh and by the ways, what rom are you running :o?
[T-Mobile Samsung Galaxy S 4] Kjc99:
Thanks guys for bearing with my newness to custom kernels but one more question

Can I run this kernel on a Rooted stock ROM or any custom kernel on stock rom? I'm having some bugs with Omega and I want to flash back to stock and use this kernel or do custom kernels only work on custom roms

Thanks for everyone's patience with my noob questions

Galaxy S4
[T-Mobile Samsung Galaxy S 4] kevinrubio1:
Custom kernels works on any rom!

Just know that the latest version of this kernel will make the smart features not work unless you're on the 6/10 version!
[T-Mobile Samsung Galaxy S 4] mamba720027:
Lol yea thats what Im starting to believe but giveing it time.

Well the rom im useing is "binary rom" in the link below. It havent update in a while but had no problems with any features not working or bugs which is more important.

love ktoonsez kernels, only problem is i find that my phone gets hotter than it used to. The cpu goes up to 50-54 degrees Celsius and the battery goes to 40-45. any ideas what i can do besides undervolt, i am -50 volts atm (-75 leads to phone rebooting)??
[T-Mobile Samsung Galaxy S 4] dragon-son:
Don't over clock as high.

Try mamba720027 settings minus some over clocking and under volting.

Don't have screen as bright. Use lux auto brightness app to have even dimmer.

Tell us what ROM you have and kernel settings and everyone could probably give some better input.
[T-Mobile Samsung Galaxy S 4] elesbb:
Lux auto brightness doesn't make it dimmer. It simply puts a mask over the entire screen area. the screen is still running at full power.
[T-Mobile Samsung Galaxy S 4] chenxiaolong:
That's true for LCDs, which have a backlight. AMOLED screens have individually lit pixels, so darker colors means less power. There's no backlight to remain powered :good:
[T-Mobile Samsung Galaxy S 4] elesbb:
Thats technically not true. There was a youtube video of an XDA tv member who had screen burn on her Note 2.

Either way, the screen is still using full display power to draw both what you are looking at and the filter.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Lux auto brightness doea not work that way as a filter like the other screen filter apps youre reffering to. Its not a filter. You need to disable android auto brightness when useing lux app. This way lux takes full control of your screen brightness and android auto brightness plays no role. So logically theirs no filter effects involved.

Heres a link below for anyone with intoduction and quick setup useing the app.

Also additional information I quorted from link below about our amoled screen and how colors affects battery performance. For anyone who likes reading :)

OLED Power Efficiency:

While LCDs are not very power efficient, they are still currently more power efficient than OLEDs for producing bright high Average Picture Level APL images. For dark low APL images OLEDs are very efficient and LCDs very inefficient. So OLED Power Efficiency and Power Management strategies become very important for bright images because they are using lots of battery power (and generating heat). By far the most significant issue is that Green OLEDs are 12 times more power efficient than Blue OLEDs and 1.8 times more efficient than Red OLEDs at producing visible light (Luminance) for a given amount of display power (Watts). In fact, Blue OLEDs consume more power than Green OLEDs but generate only 9 percent of Green OLED Brightness (Luminance). This tremendous imbalance means that images with lots of Green content are much more power efficient. It also means that color mixtures all come with an power penalty. In fact, color calibration of an OLED display so that it matches the sRGB / Rec.709 Standard would require complex color mixtures that will have noticeably higher power demands, which may make OLED calibration challenging in the near future for mobile displays until the OLED efficiencies (or battery power) increase significantly.

Also quoted the below from the article which is a feature available in ktweker by going to extras/mdnie section and turning on mdnie negative mode when reading white pages and black text.

"

For all text based reading applications it is a really good idea to set the standard Black text on a White background to Reverse Video, White text on a Black background. Not only does that use a lot less power but it improves screen viewability in bright Ambient Lighting. Start by setting Google’s search page to a Black background. Do the same for Email and other Apps and websites wherever possible.

[T-Mobile Samsung Galaxy S 4] elesbb:
You disable auto brightness so the app can adjust it instead. This does not mean that the app is able to make the brightness go below the darkest setting. This is ONLY achievable by drawing an image over top the entire screen, and adding a transparency filter to it. I bet you a thousand dollars it uses the permission "draw over other apps"

About oled screens, blacks are still using power, granted not as much as whites. But like I said, go onto YouTube and find that video of the one XDA TV member and how she talks about screen burn from dark images. Whether or not it changed to the s4 I don't know. Either way you're still using full power to draw two images. It's probably better battery life cause of the way it polls the light sensor. If you truly want better battery life, disable auto brightness and lux. Polling the light sensor takes approximately .5 ma each time it's on.

Trust me, we've discussed this a million and one times over on the s3 threads.

If you don't believe so be it. I just want people to know the truth and how coding and apps truly work.

I'm done as this is a bit off topic from ktoonsez thread. (But maybe not so much as we're discussing battery life on his God like kernel.)
[T-Mobile Samsung Galaxy S 4] mamba720027:
You obvious havent read anything from my previous post in the second link where it says useing a black wallpaper is not smart. So if her screen burns its her fault not manufacturer or anyone. Some folks just need the attention so they create youtube videos to display their stupidity.

As for "blacks are still useing power",obviously it does but not as much as white and no one wants to turn off auto brightness and manually adjust it for little noticable battery lost,its demeaning owning smartphone and haveing to do that.

Wiki explains more on screen burn-in

en.m.wikipedia.org/wiki/Screen_burn-in

"

Causes of screen burn

With phosphor-based electronic displays (for example CRT-type computer monitors or plasma displays), non-uniform use of pixels, such as prolonged display of non-moving images (text or graphics), gaming, or certain broadcasts with tickers and flags, can create a permanent ghost-like image of these objects or otherwise degrade image quality. This is because the phosphor compounds which emit light to produce images lose their luminance with use. Uneven usage results in uneven light output over time, and in severe cases can create a ghost image of previous content.

"
[T-Mobile Samsung Galaxy S 4] elesbb:
She's an XDA TV member, she wasn't creating a YouTube video for attention.

And I know what screen burn in is :P

I use an app that adjusts my screen brightness based off of light sensor at screen on time. Light sensor is polled for like a millisecond only when screen is turned on.

Off to work now! Thanks for the conversation!
[T-Mobile Samsung Galaxy S 4] mamba720027:
You can do that in lux,it also adjusts based off light sensor and adjust the polling intervals and more :D
[T-Mobile Samsung Galaxy S 4] Shawn:
All I have to say on that matter is that yes, Lux seems darker. But ALSO tints the screen a dark green. I scrolled past a picture of a baseball on Facebook with brightness at -50 and it was green shaded, and pink jutted out. Anything 0 or higher, it didn't.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Lowest for mine is -4 , seems too dark lower.

[T-Mobile Samsung Galaxy S 4] Tunasty:
Up your voltages by 25.

[T-Mobile Samsung Galaxy S 4] Monkz:
That's actually not bad at all. That will give you roughtly 4 hours of screen on time, which is pretty standard with this device.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Also set "touch boost cpu" to 1134mhz and "touch boost 2nd core" to 1 . If experience lag :)
[T-Mobile Samsung Galaxy S 4] kevinrubio1:
I'm still experiencing lag, I copied all of your settings except for the overclocking and under volting,

I'm at 189/1890 (min/max) , and only - 25 UV
[T-Mobile Samsung Galaxy S 4] mamba720027:
Save your profile then reset ktweaker to stock with Ktoonservativeq. See if lag exist then if it does,restart device and reapply settings. Cant see anything else that would cause it except if 189mhz is too low underclock for your device.

My Preliminary Report:

Upping the 'touch boost cpu' helped a lot! My annoyance was not a MAJOR lag, but was very apparent when typing. It didn't seem to register my touches quickly enough which came across as lag. I haven't 'boosted the 2nd core' and am pleased with the performance to alleged (haven't gone through a charge just yet) efficiency. Thanks for sharing your settings and, as always, thanks to KT for the best (IMO) kernel for the S4!!

Anyone having issues with thermal throttling? I set my "do not throttle below" frequency to 702 MHz and it goes way down to 378 and lags like crazy. Did I miss a setting?

---------- Post added at 08:24 PM ---------- Previous post was at 08:21 PM ----------

If I'm using a GE 4.2.2 ROM, which kernel should I flash? TW or AOSP? Can you provide me a link to download so I can install on my SGH-M919
[T-Mobile Samsung Galaxy S 4] chenxiaolong:
You can use the latest TW version for any Google Edition 4.2.2 ROMs (4.3 versions cannot use custom kernels yet due to the lack of source code) :good:
[T-Mobile Samsung Galaxy S 4] mamba720027:
Sometimes sacrifices must be made in the war on battery efficiency :p:D

Thats a weird issue u got their,not supposed to fall under 702mhz and depending on your max frequency when temperature meets 50 as u mentioned your temp limit to start throttling will begin dropping by 1 frequency if u havent change the "frequency steps" to move by 1 to something higher. Also dunno what your temp limit stop is set at.

The do not throttle above X frequency is evin stranger cause with your temperature to begin throttling set at 50 thats really where the cpu frequency starts decreasing instead of going higher.

Scenario settings.

*Max cpu freq 1890mhz

*CPU freq to stop thermal throttling 702mhz

here's a scenario of what happens temp to start thermal throttleing 50

Thermal throttling stops at lets say 39. With frequency step to move by 1 it will reduce the frequency 11 steps in accordance with temp dropping 11 degrees to meet 702mhz and stop. Now if the thermal throttling stop is less than 39 then it will override 702mhz and keep dropping untill it meets the required thermal throttling cut off temperature.

Thats how I see it working :p

High temp always trumps in thermal throttle

Sent from my GT-I9505 using Xparent BlueTapatalk 2
[T-Mobile Samsung Galaxy S 4] mamba720027:
Thats true. I never messed with the way it throttles at high temperature but that how I understand it suppose to work base on settings :)

I see what u mean now,your taught is that high temperature takes greater priority and would throttle the cpu past its cut off point with extreme heat. I retract my statement about that being true but I may be wrong. I belive the idea to reduce temp is by useing lower frequency which uses less voltage thus thermal throttling. This intern helps cpu get rid of heat quick enough as to not damage anything.
[T-Mobile Samsung Galaxy S 4] sgs22012:
Kt, correct me if I'm wrong but I understand it to be don't throttle under for normal non-throttle situations but dropping temp always tops priority list in throttling

I used the disable scrolling cache add-on and that seemed to remove any lag....

Sent from my Galaxy S4 running Omega v8
[T-Mobile Samsung Galaxy S 4] mamba720027:
Where u found that or (option) or how u do that?

So far I dont have lag but another problem,well not so much a problem now. I usually use winamp along side vipermod N music playback had some stutter when the core switch on and off from 1-2 so I figure it needs more processing power which was also mentioned in the vipermod forum about cpu intensity. Anyways I turn the 2nd core to always online and that solved it completely.

But aside with other players like jetaudio I dont experience stutters so its sort of a winamp problem also. But I can live with this,I loose insignificant or not noticable battery.

I just installed version 7/15 when I was coming from 6/10, I'm thinking of switching back to get my smart features to work!

Maybe it's my settings?
[T-Mobile Samsung Galaxy S 4] Monkz:
How do you set it to 50 without having it throttle all the time? This device will idle in the mid 30's, 40's for texting, and it jumps to the 50 degree range just through internet browsing and minor to moderate apps, and in the 60's whenever doing heavier usage.

Im assuming you have your device underclocked to something like 1.5GHz?
[T-Mobile Samsung Galaxy S 4] Gadianton:
Has anyone else had bad lag with the kernals newer than 7/7? For me it shows up especially in Chrome. 7/7 is fine, but the two newer ones will not load or scroll webpages without a very long delay. I've tried restoring to defaults and the problem is still there. It disappears when I revert back to 7/7.

Any ideas to try? This is TW, by the way.
[T-Mobile Samsung Galaxy S 4] elesbb:
You got some serious background issues then. It only throttles if i am outside or at work. In the air conditioning, it never throttles unless intesive gaming. But simple tasks it never breaks 45.
[T-Mobile Samsung Galaxy S 4] waylo:
I have the same issues funny enough, so yes. The lag I see is also apparent in Google maps, but particularly so in chrome. I didn't try the release between 7-7 and the latest though.

I'm back to 7-7 for now.
[T-Mobile Samsung Galaxy S 4] gaww:
Besides smart features, before you give up on 7/15, reset it to default and see how it works. Then try a few adjustments one at a time.

I am only using 7/15 right now on Omega 8, which is running real good. I am waiting on Wicked v5 until I go back to it, and only went as far as 6/17 on it (v4).

So I just read in another thread that I can use ktoonez i9505 kernel I have a i337m

And have been using this tmo one on it Does anyone know which is best/compatibility for my phone?

Galaxy S4
[T-Mobile Samsung Galaxy S 4] Monkz:
Right now in the air conditioning its sitting around 42-43 degrees, charging and just navigating around my phone with LTE on. But if i start to open apps like facebook, and things that use my Data or Wifi it will get into the low 50's range. Upon gaming it will generally hover in the high 50's - low/mid 60's range, and approach 70 if im outside of the air conditioning while running those heavy apps. Had it throttle like 2 or 3 times in 1 month on 70 as the throttle range, but havent experienced it throttle since raising the throttling temp to 73.

This is with KT's latest kernel and recommended settings except i have GPU OC to 627, and undervolted -70 instead of -50, Running on Task650 AOKP ROM, so its not a matter of bloat and background processes, as theres like 1/3 or 1/4 of the built in system apps and files on AOKP and generally thats sopposed to make it run cooler and not hotter as the result. But when comparing it to other peoples devices i dont think its a problem with my device, i think thats just the natural heat our devices get to. You must have just been really lucky with your device, it looks like it has its own little magic or voodoo powers of its own.I know i hit the 50's range more than occasionally, so i'm really surprised that yours can handle a 50 degree throttling range.
[T-Mobile Samsung Galaxy S 4] elesbb:
Right now it's at 37. And that's just sitting idle. Using it for xda and email texts web surfing I go to about 43 to 45. Games usually make it hit 50 then throttles down to 45 my stop temp, and it's good to go. I have a feeling your gpu oc is what's causing it.
