Noticed that when using chrome for example on dead by april, I get screen flicker. Should I raise GPU voltage a bit?
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Is this the only profile you've experienced the flickers with? If so then it may not be the GPU voltages as all my setups are UV'd by just 50 mV but it definitely doesn't hurt to test.

Try upping by 25 mV across the board and see how it goes. If all is well then UV by 5, test, and so on til you've found your sweet spot.
[T-Mobile Samsung Galaxy S 4] 93foxgt:
Its the only settings that I noticed it. Will try upping a bit. Thx. Oh and this pic is with stock battery for those that care :D
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Whoa!! By the time you hit 1% you will have reached a full day's use with 6hrs screen time! Amazing results bro :thumbup:
[T-Mobile Samsung Galaxy S 4] ahatzz11:
This is with location services on, greenified apps, about 40% screen brightness, wife on most of the time, and 3 hours and 40 minutes of screen time.

Dead in April. I'm speechless.
[T-Mobile Samsung Galaxy S 4] Perseus:
To those concerned, just FYI, Nightmare was written for the HTC and Samsung Dual Core Devices. The code was in beta stage then and it is beta now. Even on dual core devices Some swear by it, others have freezes and reboots. Your milage may vary. Yes Its a derivative of PegasusQ, which is more mature.

BIG NOTE - I recently became aware that the media Scanner service is actually playing havoc on Galaxy S4 due to forking of original Android code. Here's what you can do to avoid unnecessary battery drain.

Please follow one of 2 options.

1. Get Startup Manager from Play. It will ask for root and let it. Then from under system tab, look for "media Storage". If you find it, disable it then reboot.

2. Only if 1st option does not work, please go to Settings> Application Manager > Running Apps. You should see "Media" in the running apps. Force stop it and if possible disable it there. You will have to force stop it every time you reboot.

You should see your phone a lot cooler after this and better battery life.

SWIPE 2 WAKE –

This is an Interesting concept. If this is set, then you get to short circuit the process of waking the phone. What you need to do is slide through the capacitive buttons on your phone as if you are sliding the screen to unlock. This bypasses the step where you press power or home button to wake to lock screen and then actually unlock the phone.

Quoted from my own guide. :laugh:
[T-Mobile Samsung Galaxy S 4] Nyckrs:
Will disabling media do any harm? Can we just use titanium backup and delete media storage?
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
You will need to reboot the phone for it to recognize recently added media files. Easy fix would be to use a 3rd party app in which allows for manual rescan, such as Poweramp but if media scanning isn't causing you severe battery drain then there's absolutely ZERO need to do any of this. Sometimes after flashing new ROMS i forget to do this and I still manage similar results as i did when I actually had disabled it. My advice would be if it's not bothering you then don't touch it.

EDIT: You can also use a 3rd party media scanner app so there would be no need to reboot.
[T-Mobile Samsung Galaxy S 4] Nyckrs:
I'll just freeze it and see if there's improvement. I do notice it running 36% of the time but didn't really affect battery life much. Will report back. Thanks
[T-Mobile Samsung Galaxy S 4] makenmoney82:
Its actually a system manager application should I do it anyway
[T-Mobile Samsung Galaxy S 4] Nyckrs:
When i froze the media storage none of my ringtones work. guess i'll just leave media alone.

Hey guys got a question. I have a verizon S4 and have been using bless the child which is freaking KILLER for battery life. Thanks!!!

My question: Is there a way to change the screen lag? When calls come in or if I am in the middle of a call the screen on doesn't happen I have to hit the power button to get my screen on. What setting should i change so I can get my screen on sooner when calls come in or during the call so i can switch calls switch to speaker or simply hand it up. Thanks

[T-Mobile Samsung Galaxy S 4] LuigiBull23:
It's safer converting a system app to a user app before Greenifying but go for it if you like. As long as you have a nandroid you have nothing to worry about.

What ROM are you on? Are these the only settings you experience screen wake issues with? and have you tried bumping up the screen off profile Mhz?
[T-Mobile Samsung Galaxy S 4] doctordroid:
I am on the Eclipse TW 2.0 ROM. I have not changed any settings. I usually don't mess with goodness but this is the only flaw I found. I guess I will bump those settings up if I can find them... thanks...

---------- Post added at 08:12 PM ---------- Previous post was at 08:11 PM ----------

okay so i bumped up the screen off profile mhz to 189... should i disable the screen off Mhz call option?
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
KTweaker > Extras > Screen Off Profile Mhz

Try raising it to something like 594.

That would be your second option but does not need to be done as long as you raise your screen off Mhz a good amount. You may need to raise it further than 189 but test it out anyways. Any issues then raise an additional 2 steps or just disable screen off Mhz call.

Super bull just won't die damn it! Haha

Battery reborn says 7 and a half hours left. Only draining at 3 . 5 % screen on and 2.5 off :) greenified like crazy and seems to be fine. Basically all non system apps minus Instagram what'sapp and stuff I need notifications from isn't greenified. Been testing whether or not greenified gnow/gsearch and gmusic are stable and so far yes they are. Along with the play store as well. Location services off and toggle on as needed and no modded gsf.

Oh and for anyone on a college campus that you might be switching between wifi routers constantly as you walk around from class to class. Disable wifi till your stationary. It helped me ALLOT. Even turning the advanced setting on/off in wifi did minimum help. I really noticed hours worth of difference when I just turned it off until I got seated in class.

The only thing I could probably do better is do the mod gsf to make my phone sleep almost instantly but I like my notifications and I do use Google services fairly frequently just to piss off my siri toting friends :p

[T-Mobile Samsung Galaxy S 4] mamba720027:
Yes, that's indeed impressive results considering that crazy stats with battery to spare. Thanks for the feedback as always :D:thumbup:

I actually saw the specs for the Sony Xperia C3 quadcore clocked @ 1.2ghz although different chipset and all I taught that if that device can run at such speed fluid I shoud be able to sort of simulate something similar since our device is plenty powerfull and fast plus ours would consume less power considering screen type/size and such and thats how I derive at that profile in the final release. I know attempts were made at similar setup but for me getting it as fluid as possible were the challenging part. Something Luigi also wance mention in a post sometime ago about fluidity in battery conservative setups.
[T-Mobile Samsung Galaxy S 4] MikeC4510:
Here's my stats on Green (without script) and brightness at about 40%. This is definitely my new favorite. Will try with script and perhaps with an underclock of 189mhz.

I'm a noob as far as using KT Kernels. After looking at the impressive results shared by fellow members I'm trying latest TW KT Kernel with "Smooth Criminal" profile; however how do I make sure that the profile is applied or in effect? I did follow the steps in the OP but wanted to be sure.

Any help is appreciated. Thanks.
[T-Mobile Samsung Galaxy S 4] CamFlawless:
In KTweaker, go to CPU settings to ensure that the values in there are the same as what is stated in the profile XML file. If you chose to 'restore prefs from SD Card', then you are good to go. :)

Hey [MENTION=4883551]CamFlawless[/MENTION], where can i find the updated versions lf Asking Alexandria, etc. Because in the OP are outdated i think and in the ktweaker shop is also outdated, i remember there were profiles that were v2.

I am slightly biased towards the profile(s) that I created myself, but some of my favorite combos include: Overactive Imagination/Hydra, Misanthrope/Hydra, Whispers in the Dark, and Smooth Operator V6/Smooth Operator Infinity.
[T-Mobile Samsung Galaxy S 4] a103:
Thanks. I'll give it a run. One more question. I've seen that people ask for a kernel to settle for a day out two. So it is after first couple of days one will see the amazing effect a Kernel can have on battery as well as performance? Sorry for asking too many questions but I've never tried custom kernel before; I was using stock which came with the ROM itself.

Thanks for all your help so far.
[T-Mobile Samsung Galaxy S 4] CamFlawless:
It's just a general rule of thumb with ROMs and kernels. Give them some time to settle before jumping to conclusions about it saving or not saving you battery/performance/etc. With this kernel, you should notice performance improvements immediately, but be patient on judging true battery performance.

It would also be beneficial to use better battery stats to ensure that you don't have any wake locks draining your battery.
[T-Mobile Samsung Galaxy S 4] a103:
Yes I'm seeing the performance difference. TW was never snappy before. I'm thankful to members (and their posts) like you who kinda encouraged me to try KT Kernel and I'm happy that I did.

I'm using betterbatterystats as well. Will monitor wakelocks too.

Thanks...

Hello.

I have A question. I am using kt kernel set on ktsoonertiveeg with cfg governor.

My issue is when my screen is off, my tunein stream skips. If I turn on my screen it plays nicely (depending on data strength. )

What should I change to fix this?

Thank you for any assistance.

[T-Mobile Samsung Galaxy S 4] mamba720027:
In ktweaker Under "cpu settings/media Bluetooth settings" you could set a higher min cpu frequency while playing media or streaming over Bluetooth.

Another options is to enable the "disable_hotplug_media" by placing a "1" where it is located at "cpu settings/governor adjustments/only screen on"

This disables the hotplugging logic and brings the 4 cores online alltogether using the low frequency while screen is off.
[T-Mobile Samsung Galaxy S 4] mamba720027:
New experimental profile added to dropbox. No name to it just Highly Experimental but safe for anyone to try as its not set to apply on boot.

Its a 3 core profile tweaked undervolt by unconventional method. Also experimenting with the scheduler which im not a big tweaker on but with enough info from a CM thread I was able to understand the row scheduler in order to tweak it and will keep improveing on the scheduler part and profile.

For now I think load time n responsiveness have improved on apps and im now useing elesbb warp drive TW 4.4.2 Rom. It feels very fluid on my end with exceptional battery improvements. Some screenshots below.

I'm testing Smoothing operator v6 + smoothing operator infinity and Green Quadcore + Green Conservative. I love the first one, very smooth and a bit better with the battery than KT V6 (it is my impression).

The second seems to be veeery god in term of consumption, but it is too laggy for me. I can't use it as my regular configuration... but it is a good option when I have to spend a whole day out of home without charging possibilities.

There is a huge difference in terms of performance between this two profiles, I think that more than in consumption...

Generic question on AOSP ROMs - Can I use this with ART? What's the difference in performance and battery life when this Kernel is used with ART Vs Dalvik? .

I mostly use balanced profile and scripts.

Any insight is appreciated.

One more question - I flashed this Kernel on my CM11 Nandroid Back up (with Art). I tried different balanced profiles and found it was bit laggy specially the animation was stuttering. It wasn't a big deal however was it due to the back up. Should I do a clean install of ROM and then flash the Kernel. If someone can pitch in with steps to follow to flash this kernel after a clean flash of any ROM I would appreciate that.

I really want to try this Kernel on CM11.

Thank you.
[T-Mobile Samsung Galaxy S 4] CamFlawless:
Green profile and script is too good, you guys.
[T-Mobile Samsung Galaxy S 4] benzxi:
if the lagginess of anims, and a more snappier feel is infused with this profile, i'd give it a thumbs up. :)

i've been using overactive/hydra and interchanging from smooth criminal+ smooth infinity
[T-Mobile Samsung Galaxy S 4] CamFlawless:
The small lags are reasonable for me considering the nature and battery life of the profile. Definitely a small trade off but well worth it considering I get two days of usage with no problems. It helps I am not a gamer and use mainly PowerAmp, Tapatalk, Instagram, and Facebook. A wonderful profile for my usage behavior.

P.S. glad you are enjoying overactive/Hydra. Definitely my go-to. :D
[T-Mobile Samsung Galaxy S 4] mamba720027:
Thanks for the concern and I do appreciate the feedback. While it is possible to make it smoother it will also bias against its battery conservativeness at this point.

I would recommend you to try raising the max frequency one step see how that feels. Give it another stepup if needs too.

Unfortunatley ktweaker has stopped

Hi whenever I boot my phone I keep getting a message that "unfortunately ktweaker has stopped." Any suggestions how to permanently fix this? I've tried various solutions such as wiping catch, clearing app data, etc and reinstalling the kernel.....
[T-Mobile Samsung Galaxy S 4] CamFlawless:
Force quit KTweaker, clear app data and cache, backup the contents of the /sdcard/ktweaker folder somewhere, delete the entire ktweaker folder. Now you should be able to open KTweaker and have it operate correctly.

Should I reboot and restore the /sdcard/ktweaker after I delete the apps data and cache?

You should not have to reboot after deleting the internal folder. I would however, advise from restoring all profiles. In particular, be sure to delete the "currentprofile.xml" before moving your profiles/scripts back into the KTweaker folder on the internal.

If you downloaded Ktoonsified V6 from the shop within KTweaker and applied it, you are good to go. Do not worry if they do not match the description found in KT's kernel thread(s). The shop version is up to date. KT doesn't always update his settings post within the thread to reflect changes. ROW is the correct i/o for the latest profile version.

To be honest, it was left on by mistake. But, it will not hurt battery considering it does not grant the kernel permission to hold a wake lock. That also mean at it may not work every time. If you don't have use for it, like myself, just turn it off. But you don't notice a thing if you don't.
