There's really nothing much left to say as what I was going to mention has already been stated. However, in addition to that I would like to say that the more features added/merged into a ROM the more difficult it is to keep that same optimal battery life you once previously had. They require so many background processes to keep the phones running as smoothly as possible The kernel will only push out what is fed to it by the ROM and apps installed by the user so I'd like to think that it's more the ROM than the actual kernel, at least for the most part in this case. Understand that ROMs today will cause more partial wakelocks than they did a year ago or even 5 months ago, depending on what exactly is running on that specific ROM. I could be wrong but it looks to me like your phone is having a pretty rough time sleeping. As I tell everyone I would suggest installing Betterbatterystats to monitor everything occurring "under the hood" of your device, thus better determining the cause to your battery drain issues. I would also recommend matching your favorite kernel build from 11/11 with a ROM from that same point in time simply just for battery testing to see if you get similar results. Now in regards to kernel builds alone, I too have had roughly around the same battery life over the course of these KT747 builds but the same has applied to various kernel builds I've tested across the board.
If you can possibly confirm none of this to be the issue then it must be the battery itself. Purchase a new one and make your own definite comparisons. I wish I had more to tell you but this is all I got to help you unfortunately but test out what's been suggested by us and report back as soon as you can and if you do so wish to..

mw86,

First of all, I acknowledge you as one of our top developers, so your opinion weighs pretty high on my book. But I have to tell you, battery life does indeed fluctuate for many reasons. Point and case: I removed the. 11 nov kernel and installed last night the April 11 kernel, which was the last kernel released for 4.1.1. Went to bed with 65% and woke up with less than 20 percent. Same ktweaker setting file; nothing else was changed except the kernel. I used the kernel removal tools before swapping kernels. So, statistically speaking, there are no other variables on this equation. The 11 nov kernel burns about 12% of battery life overnight; the 4-11 ate 45%.

Again, you're the expert, but all I'm doing is experimenting and taking notes. I upgraded my ROM to 4.1.2 (MOAR) and battery life was even worse.

I honestly believe that the simplicity of the earlier kernels does help battery life. And for the record, I own Six batteries with two chargers. So I am not concerned with battery life as much as folks that have only their one stock battery. I've gone through 5 S3s for various reasons (bad screen, overheat, sudden death, and fried GPS chip).

The bottom line is that us users are very fortunate to have such a robust team of developers, to include you. The conversations among us have always remained professional, unlike other forums. So I'm honored to be part of this all.

Although I may have experienced optimal battery life throughout these builds I do have to agree with you on the simplicity of the earlier builds. You can't deny the fact that with simplicity or "lack of features" on those builds you're bound to gain a significant amount of battery life with those as opposed to the current ones. Regardless, I must only speak on personnel experiences as well as what's been reported by users.

Luigi,

Thanks for your contribution. Again, I'm not trying to say that I have any issues. My S3 is purring like a kitten. I do have cpu spy and my phone goes into deep sleep 90% of the time. So, I'm good.

The reason I wrote my comments was because I've seeing a string of comments complaining about battery life with the latest kernels. That was all. And if you noticed, I posted my comments on this new thread and not on the main forum, mainly because I wanted to keep this conversation low key.

Again, just trying to share insight that might contribute.

I see where Jag50 is coming from too so it seems to make semse with added features such as our own manual implementation of thermal throttle which requires monitoring temps and setting max mhz as just one example of a feature very helpful and useful but at a small cost of some added resources.
The less of these features likely less keeping kernel/system active in background. So acknowledging that it seems thats not the issue Jag50 may be facing. Seems just loading kernel straight up something is keeping it awake.
Jag50 your a bright person you likely don't have an obvious thing like swipe to wake enabled right? Basically even if it seems normal drain old kernel and back to crazy drain fresh install of new would say its kernel its just as likely the new stock rom with all new features keeps system awake on new kernel just because something new in rom. So the effect of better battery makes sense on old kernel where less flags and options etc are running as im sure in latest tw builds there has been a ton of code added. I don't think ita battery based on what youve said. Ive abused mine and they dont get max but still right up where they were for me.
Example Ktoonsez had a hair pulling week on his phone which is his buisness work phone too so consider his stress, he had exact drain you do now. It in the end was his wifi router at home. He wasn't using net but left wifi only on at home and it somehow due to faulty hardware caused drain on his phone just being idle and about 20-40% down like you. New router solved it. So Jag50 lets continue to investigate and if i were you try seeing as much as you can on wake locks or diagnosing radio drains etc. If you find for example it never happens on airplane mode you have a start at figuring it radio related. Theres a lot of factors and such a drastic drain seems many kt users would have reported but point being kt had a issues to diagnose and solve similar he even thought was his kernel once... poor guy but no... So goes to show sometimes the last thing we think is the cause. Keep us posted Jag50.

mw86,

Much honored for you taking the time to discuss this issue. I completely agree that there might be other factors at play here.

What I've done is create several nandroid backups and in that manner I can continue testing new kernels and ROMs. I do full wipes before restoring and never have had issues restoring.

This whole conversation will fade away anyways as newer smart phones are released. I'm not upgrading to the S4, but will stay current on that forum.

In any event, thanks for your suggestions and comments. I truly believe our kernelizer forum is the best in xda.

Well it really depends on which group of builds you're referring to but you can check the most recent build for each group by the dates included in the file names. For example, 5/17 is the most recent 3.4 build released by Ktoonsez.

Android OS is taking up over 50% of your battery. Any idea what may be consuming that? Do you have many apps running? Is your phone sleeping? Have you tried using apps such as Betterbatterystats to better monitor and determine what's running "under the hood" of your phone? If not, I would suggest doing so and posting some shots of "Other", "Kernel Wakelocks", and "Partial Wakelocks". Hopefully I or someone else can better assist you then.

all i did was switch kernels. i was running leankernel and it was great. i switched to kt to try it out and i always get this. no matter what. thats why i have stayed away from kt. the phone doesnt go into deep sleep either. i had swipe to wake enabled and i read somewhere that that causes drain. i disabled it this morning and now it seems to be going into deep sleep. so i will monitor the battery for a couple of hours and see what happens.

Different kernels will run some different aspects of your entire phone, especially depending on the ROM your running the kernel on. . Unfortunately, it seems though as if something about this kernel is constantly causing your phone to stay awake. I don't want you to miss out on this beast of a kernel so If you do have any hope left in this kernel then please do install that app, post those screenshots I mentioned, and I'll personally help you in identifying the cause if you can't do so yourself.
Hopefully that swipe to wake is the main culprit.

I agree. Kernel devs need help from people with problems in order to make their product better. Please don't drop it right away. While KT may not be the kernel for everyone, maybe not even you, if you have problems it is your responsibility as a guinea pig... err... user... to help report and test issues :)

Turned off swipe to wake and battery life seems much better but still not great.

Considering you've got wifi on the entire time this really isn't bad at all. If you wanna improve it even further then take care of your wifi. Try turning it off when not in use.
Also view your partial wakelocks to identify exactly what apps or widgets are running and, if possible, Greenify most of your apps

It looks relatively normal but your screen is nearly 50%. Try dimming down the brightness to about half or at least reduce the times it increases towards it's max when using it. As far as android system and OS goes, it's not taking much off your battery and as you can see the phone is sleeping for the most part. It just looks as if you got small background processes going on that has kept the phone awake for 45 minutes out of those 3 hours. You can post a screenshot of your partial wakelocks if you like. it may also have something to do with your screen off states. What are your Ktweaker settings if I may ask?

S2W is a big drain to the battery if left on all the time. Glad you figured that out. I only have it enabled when plugged in. Still really like the feature.
One question I have, did you rename the files? As is suggested in the KT thread.

Oh yeah! What's the GPU governor control?

And could you guys add the Zen I/O Scheduler and possibly GPU speed selection for Android Tuner support?

I'm working on the second part myself but don't think I'm as quick as this team at it. And the Zen scheduler is quick and easy... Possibly the best scheduler out there... at least it's the best one I've found.

    KT747 [Kernel] Builds [Discussion] ◆ALL VARIANTS◆ [AOSP/TW] ★KTWEAKER SHOP★

    ALL CREDITS GO TO THE ONE AND ONLY KTOONSEZ FOR THIS AWESOME KERNEL AND GIVING ME THE OPPORTUNITY TO PROVIDE THESE BUILDS.



    I am not a developer and am in no way affiliated with Ktoonsez or his work. I’m just a simple member of the XDA community who happens to be a huge supporter of this kernel and its creator. This is just my way of giving back. I am aware of some of the recent issues occurring on the Linux 3.4 base builds and this is my response to that:


    This is by no means intended to replace any of the original KT747 kernel threads. The purpose of this thread is simply to work in conjunction with them by providing a variety of 3.0 and 3.4 builds for users to experiment with and see which versions function properly on each of their respective phone models. So I’ve gathered MOST of the earlier as well as current builds that I had hidden within my pc and am sharing them with the public. I hope this makes a difference for all you guys. ENJOY!! :good:




    POST #2: Reserved for T-MOBILE and AT&T users

    POST #3: Reserved for SPRINT users

    POST #4: Reserved for VERIZON users




    All posts will be updated regularly upon future releases so please be sure to refer back here for all builds from this point moving forward! :)



    Please make absolutely sure you are downloading from the post intended for your phone. Nor I or Ktoonsez will be held liable for anything that may occur to your device. So please...


    ***FLASH AT YOUR OWN RISK***



    ***** IMPORTANT *****
    If you are using my ktoonservative governor with the Touchwiz JELLYBEAN version, you should rename /system/bin/qosmgr to /system/bin/qosmgr.bak to prevent battery drain


    Always do the following AFTER installing the kernel:
    1. Clear cache
    2. Clear dalvik
    3. Fix Permissions




    If you are UPDATING the kernel, follow my recommended procedure for best possible results:

    1) Backup current Ktweaker settings
    2) Navigate to Settengs > Apps > Ktweaker
    3) Clear cache and data then force stop
    4) {Optional} Open any root browser, mount as r/w, then navigate to /system/app/ and delete Ktweaker apk
    5) {Optional} Clear all Superuser logs
    6) Reboot Recovery
    7) Flash kernel
    8) Wipe cache/dalvik
    9) Fix permissions
    10) Reboot
    11) Restore Ktweaker settings













    NOTE: If at any point Ktoonsez no longer wants this thread open it will be closed without question.

    Welcome to the Ktweaker Shop!

    Here you will find all of the pre-configured settings provided by myself and some of our fellow users. As a proud member of Team Kernelizers, I am offering a variety of profiles specifically for S3 users with their personal needs in mind as it's pretty clear no one favors the same governor, scheduler, etc.. Any suggestions are always welcome. All future settings will be added here for sharing and discussing our settings as well as gaining approval on a profile to be added into the built-in Shop in Ktweaker. Keep in mind that results will always vary per device regardless on the settings being used. Apply what works best for you and your phone. We're here to help eachother out and with more options comes better experiences for everyone running this kernel. Big thanks to ALL who have contributed!


    So shop around.. pick and choose.. load and go!!



    Installation

    Download links will include the specified profile(s) as well as an "Adjustments" and an "About" file. The "Adjustments" file is just for easy view of all changes made to a profile compared to stock settings.

    1. Download the file(s) to your phone. In case of .bin files, optionally rename the file(s) as .txt
    2. Copy ONLY the profile(s) (DO NOT copy the "Adjustments" or "About" file) to /sdcard/KTweaker folder using a file Manager of your choice.
    3. Open Ktweaker app and click on "Restore Prefs from sdcard".
    4. The file you just copied should be listed there. Choose the one you want to apply.
    5. After applying, make sure the "Set options on boot" setting on the main menu of KTweaker has a little green text bellow confirming that the settings will be applied upon reboot.
    6. Profit!



    Balanced Bull: Reloaded (updated: 11~15~13)

    These settings are very special to me as they were my very first, dating back to the Galaxy S3, and has gained an incredible amount of feedback. It has become notable for it's fairly smooth interface and amazing battery life. If this stacks up to your standards then I encourage you to use it!





    Nightmare To Remember

    This will likely become your beautiful, never ending nightmare.. It offers a unique balance between battery and performance but unlike Balanced Bull, it is slightly more performance oriented due to the more aggressive scale up to max CPU. However, only 2 cores will be used for the majority of the time so you can still enjoy a nice buttery smooth interface with just enough juice to last you through the day. :)





    Bless The Child v3 (updated: 10~25~13)

    Based on Ktoonservateq and aimed towards battery. This is specifically for all the battery hungry users out there wanting to conserve as much power as possible. So don't expect the BEST but rather decent performance out of this one.





    Feed The Machine

    The exact opposite of Bless the Child. This is a performance oriented option for all hardcore users. If battery isn't a priority for you then this is a great option.





    Day Of Reckoning

    Very similar to Nightmare To Remember but is aimed slightly more towards battery without deteriorating much of the performance. It is based off the Pegasusq governor.





    Super Bull 2.1 by @MavereXx (updated: 9~24~13)

    A derivative of Balanced Bull but aiming towards more extreme polarity of performance and battery life. Stable Undervolting for i337, i337m, m919, and i9505 CPU and GPUs. Overclocks up to 1998mhz going all the way down to 81mhz without causing severe lag or stuttering or slow wake ups. Tries to find the right balance between ultimate performance and battery life.





    Dead By April v2.2 (updated: 11~15~13)

    This profile attempts to bring some of the best battery life possible to your device. It is similar to Bless The Child but takes things a step further . It now focuses more on snappiness but still maintains it's well known battery conservation. It manages to maintain a smooth ui for your average daily use.





    Project Icarus by @mamba720027

    So some may wonder why the name "Icarus",why not Hyper Performance or Deadly Good Battery.
    Well the reason and to begin explination,short history.
    Icarus is a greek mythology who is seen today as a mythical pioneer that tried to conquer the skies.
    I like that mythology cause it kinda corresponds to my own saying "fly high or fall hard" which means to aim high or fail trying. So their you have it folks and thus the profile name "Icarus".

    And onto explination of each profiles.

    The first is "Performance" which is catered for straight out performance with also good battery performance.
    This one is for when u dont give a rats flying balls about battery really and just want everything super fast and smooth. But you maybe surprise of battery performance. I recommend everyone try this profile first. My current favorite :D

    The second is "Conservative" this is for those seeking performance but also better battery performance than the first.
    This one is the middle man or lady as u may want to refer to it. It gives the best of both worlds,performance and battery. So if the first leave you stranded then fear not, this is the one to turn too :cool:

    The third is "Kamikaze" which means "god wind". It either knocks the daylight out of your Galaxy S4 due to its high undervolteing and mean intent on Battery Performance but still snappy.
    This one the undervolting is of my personal voltage table that runs stable for me with other tweaks. If it runs successfully for anyone else then battery performance may be great.
    This one is for those that likes the thrill of trying something new and unsure if it will work :p





    Undisputed 3 (updated: 12~11~13)

    This is a universal performance setup in which combines the essential elements of other profiles by providing equal battery life, speed, performance, and stability to bring the ultimate experience to your device.





    ECLIPSE v2 (updated: 10~25~13)

    This is a performance oriented option where great battery life is also expected to intervene. This not only will bring an incredibly stable, smooth, and snappy feel to your device but will also benefit towards longer lasting battery so you can love and enjoy your phone the way you were meant to. :)





    Asking Alexandria

    Another battery driven profile in which focuses on saving as much juice as possible while also maintaining stability and providing an extremely snappy feel to your phone. It is quite possibly one of the smoothest and snappiest battery saving profiles available.

    Why Asking Alexandria?
    It's named after yet another one of my top favorite metalcore bands and I chose this because Alexander The Great basically ruled the world at one point and "Alexandria" is the female equivalent to that name, which has become known to mean the "one who comes to save warriors".
    "Asking" was an addition to the title name as an indication in the sense that we are all asking Alexandria what she can really do to our phone.






    Smooth Criminal by @ORT14

    Why Smooth Criminal you ask? Simple, this profile will keep your phone running as Smooth as ever, so smooth that it is Criminal to still get this type of battery life. Last test my phone went over two days with six plus hours of screen time without a charge (see below) while still running super smooth. This profile will change your life (well maybe not). Give it a try and let me know what you think.





    Super Battery Saver 3.0 by @MavereXx (updated: 10~7~13)

    This profile is not about performance, even though its surprisingly smooth. Gentle Undervolting.. your s4 now has only a 1.1ghz processor. .. but remember: This is when battery life is all you care about!





    Project Daylight v2 by @mamba720027 (updated: 12~23~13)

    Day Light is focused mainly on battery conservation. I felt that its useless if its not smooth and lags alot so I add performance into the mix createing a profile that offers both while its first and foremost goal "battery performance" is still preserved and not diminish. This profile is yet unique and on a different level from my early release of "Icarus" :)

    The contents are 3 profiles unique in their own way, "Daylight", "Daybreak" and "Experimental" along with a "Extra" folder containing wallpapers I created on our S4 for fun while testing :D:p . Kind of gives me some inspiration and sense of feel of what my objective is.

    Daybreak is a crossbread profile of my Icarus Performance profile and Daylight. Its simply utilizing the performance power behind Icarus Performance profile while useing Daylight profile governor settings as its core to boost battery performance :)

    The experimental profile is heavily undervolted/Underclocked with tweaked scheduler and governor. I taught if some of you could run it stable then it may produce great or mix results ;)





    What Lies Beneath

    This is an extreme battery performance setup in which essentially transforms your quad-core device into a dual core device.

    Why "What Lies Beneath"?
    You'll find that during light to moderate operations the cpu remains at lower frequencies for an extended period of time and will only jump to max when needed. Although it's clocked at a max of 1.3ghz it maintains a surprisingly smooth and snappy feel to your device at such low frequencies. This is where battery life is also expected to come in to play as well.






    Ktoonsified v4 (updated: 1~18~14)

    This profile was put together by none other than the BOSS himself, @ktoonsez! This is a performance oriented option in which also offers a great deal of battery life. Haven't tried these settings yet? then what are you waiting for!! Load em up and be prepared for one of the smoothest and snappiest experiences ever!





    Sleeping Dragon by @mamba720027 (updated: 12~23~13)

    Sleeping Dragon V2.1 Single Core
    This is a single core profile aimed at consumeing the least battery for a time when you will be away from home or at work and away from the charger. It was a profile i played with at first as i did not expect it to mount as much with apps and system UI needing a right amount of performance from a CPU to meet todays tasks in performance. In the end i was able to tame the dragon and make it work as best as possible to achieve its goal

    Sleeping Dragon V1.2 Quad-Core
    This is the counter part of Sleeping Dragon Single Core but with many tweaked parameters to make it a fully functional 4 Core base profile in hopes to achieve close or same battery performace as its single core entity. Unfortunately i still am not sure if it measures up but what i know from previous test with settings @Stock it hold its own in battery department. I am pleased with the results although i would wish to see some light usage results from users. I am pleased to present users with this 4 Core or Quadcore profile :)





    Smooth Operator v3 by @mamba720027 (updated: 12~23~13)

    This profile utalize all 4 cores on demand and serves as being a balance between battery and performance. Its as smooth as possible and utalize the full cpu power while operateing sensibly in governor scaleing.





    Hydra

    Eclipse and Kamikaze clash with one another in this hybrid profile (BIG thanks to @mamba720027 for the amazing work done on Kamikaze!). This is perfect for those who favor one or both of these profiles. With the merging of some of the essential performance and battery elements of each profile as well as a few minor adjustments, this one also stands as it's own profile and it flies!.





    Notorious by @PiggySmalls502

    This is a derivative of Feed The Machine. Hotplugging was turned back on and I/O scheduler was switched to ZEN along with a few other minor changes to the profile. It's aimed towards slightly better battery life but doesn't deviate too much from the performance aspect of things found in the original profile.





    Ghost Rider by @galaxys3man30

    this setup can benchmark on 1890,1944 and 1998 and its been really good on battery even thou its a performance setup think im going to call it ghost rider cuz its a sleeper yea it shows good battery life but behind that is the raw performance that is on demand when needed.





    *Stardust v2* by @mamba720027 (updated: 12~7~13)

    This Profile I put together is based on the "AbyssplugV2" governor.
    Everything is tweaked and the profile can run by itself or either use the "smooth operator V2" Script or Luigi's "Hydra" Script.
    Both are found in Post#8 of the OP. The choice is yours.





    Infamous 1.0 by @PiggySmalls502

    Infamous is a work of pure and utter boredom, and a desire to use the SLP governor. Profile uses very low CPU frequencies, yet still runs very smooth, while still seeing great battery life.





    Crimson Dragon v2.1 by @mamba720027 (updated: 1~8~14)

    This is a profile that i put together from a lost in the thread Dual Core profile "Lazy Dragon". What was suppose to be a V2 Update of it turned into a 4 Core profile and something totally new, Crimson Dragon. This profile is a variable of Performace and keeping things balance. Its very smooth on TW and produce great results on AOSP as well threw testing and feedback. Please enjoy this new addition :good:





    3hands by @sew3521

    This profile is a combination of my 3 favorite profiles; Ktoonsified v2, Project Icarus-Kamikaze, and Balanced Bull: Reloaded. Each of these 3 different profiles has great aspects however I thought I could combine them to make one super efficient profile and this is what I came up with. There is an extreme amount of undervolting going on here however my S4 runs extrmely stable (Sprint S4 purchased on release day) and thanks to the Balanced Bull and Ktoonsified portions of this the interface is very snappy.





    Lateralus v2 by @CamFlawless (updated: 1~15~14)

    This profile was designed in an attempt to strike a balance between battery and performance with a focus on conservative CPU scaling to maximize battery life while maintaining a smooth, fluid, and stable UI. I tested it with the Hydra script, but your personal favorite will work all the same.





    Lightning Blade v2.2 by @mamba720027

    This profile is aimed at performance and efficiently uses the 4 cores somewhat better than my first performance base profile.Â
    Although it's aimed at performance it could conserve on battery as well because of the way cores are handled. If you play lots of games that require speed and processor power then this profile provides both.





    Moonlight v2 by @Tunasty

    This profile is based on Ktoonservateq and Mamba's Daylight profile. This profile is aimed towards battery and be able to use your phone without any lags. Performance has not been sacrificed either. Max Mhz is 1458 which works out pretty awesome. KT's AWESOMEEE kernel and Moonlight profile will make you fall in love with your phone ;)





    SRV v1 by @s3icc0

    Basicaly it is ktoonsifiedv2 with few changes focused to battery life. It is well responsive and I have no problems playing games like RR3. + The frequencies are more stock, but it is possible to go down with max frequency to 1680MHz e.g. I have been playing with the treshholds to let the phone stay on higher frequencies and to get there faster and of course it will scale down later but faster ...
