A few things you can try. Before you proceed know that with any device over-clocking will generate more heat. Ambient temperature will affect how cool your device stays. Needless to say if you are in a hot vs cold room or a room above comfort temperature of 72 degrees Fahrenheit expect slower heat reduction. The profile is set to maintain thermal throttling which reduces cpu max speed when temperature too high for safety and stability but can only do as much in the describe environment.

On to recommendations.

Alright first i know performance is a must but remember your CPU was design to operate at* a max clock speed of 1890mhz while its bumped up too 1998mhz which is not bad but not all device is the same.

>>

I advice reducing the max clock speed to 1782 or one step lower and reducing the min cpu speed to 486mhz. This may affect performance slightly but may also help with the heat dispension.

Also disable "sync extra cores screen On". This feature helps in performance with the tweaking KT made in regulating the other 3 cores operating at same clock speeds speeding up tasks. In your case turning it off may allow those cores to operate at lower speed when not needed which will help reduce heat because of less power consumption.

I think those two things are your best bet on adjusting while staying on KT-Gaming profile without swaying too much from its purpose as a gaming profile.

Their are other performance profiles in the K-Tweaker Shop and in OP that you can also experiment with using for a few days and see how well they compare if nothing else works. Keep in mind the heat will not damage your camera or components in phone. Just don't have it plugged in on the charger while doing gaming cause then that's not good.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Ok seems you're looking to pro-long your battery life where you already have decent battery performance but due to the high power demand of "uber partner app" you can't get threw your daily routine even while charging.

Having it plug in while using the app won't help it charge faster nor using fast charge because the principle involving battery cells won't allow it. If anything your battery will go from warm to hot damaging the battery overtime because some of the cells will simply loose its charge or potential to hold a charge.

I recommend trying Franco "Per-App Modes" app which is found in the playstore. It will allow you to control how the CPU performs such as setting CPU clock speeds for the app you mention among controlling other things which may reduce power consumption and pro-long battery further.

Last resort you can get a second battery or if you want to avoid the hassle of swapping and don't mind the bulge go for an extended battery. It will get you threw the day.
[T-Mobile Samsung Galaxy S 4] PhrostB:
thanks for the advice. I think i found a reasonable work-around. see I drive a minivan that has a power outlet in the back, so today I decided to rig up an extension cord that runs under my carpet to the front of the car where i have a regular charger (not microusb -> usb) plugged in. I still lose battery but much less than with the old usb -> power charger.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Great!!:thumbup: glad you had that sorted out :)

been tinkering with regard to getting the performance needed not to suck at SGDZ without the heat of ktgaming, I came up with an edited version of feed the machine v2 with just the main settings changed and a switch to userspace governor. so far it's been like butter so I thought I'd share it
[T-Mobile Samsung Galaxy S 4] roiikka:
I got the stuttering audio problem fixed on the Galaxy S4 M919 TMobile. It should work on the other ones too.

It would stutter with the screen off unless you go to the settings and re-tap on the governor you were using. This fix would last only until reboot which is a fix i found out how to do personally.

What I did was increased the "screen off mHz" to somewhere around 1,000 , set the "screen off governor" to a different one with higher performance (mine is "ondemand" with screen off set to "performance").

This also might help it to do the "re-tapping on the default governor being used after you reboot it" fix that I mentioned above. Not sure. It just sets the governor to a different one while the screen is off then sets it back again when you turn the screen on.

Also I read that changing the read-ahead values might help.

It all seems to be working now.

It was bugging me like crazy and I just had to post this. I know there are alot of people out there with a Galaxy S4 still and that love this kernel.

My IP/TCP congestion control is also set at "highspeed" .

If I understand correctly, the display stat is a sum of the energy used while the screen was on. It's not only the power drawn by the screen itself. So if you draw less cpu power while the screen is on you'll get more screen on time
[T-Mobile Samsung Galaxy S 4] Perseus:
With due respect you might be barking up thee wrong tree. You could be struggling because a partial wakelock is sucking your battery dry ?

Next time i get stats like that i will post BBS screens here....... But my battery life is bad when the screen is off and even worse when the screen is on....... In numbers...... 30% battery for one hour of web browsing (underclocked the cpu by 75 and the gpu by 100 ......) which governor and which scheduler should i use?

Atm Iam on nightmare and row without any changes (min 378 , max 1242.... Or something like that^^(gpu at 320)

But before i used ktoonsez own settings he posted on the forums somewhere......

[T-Mobile Samsung Galaxy S 4] MavereXx:
After much experimenting, *too much* undervolting (even -75) causes the device to work harder to do the same tasks causing slower performance, and may be unstable depending on your device and voltages. Thats one of your issues, mostly for your higher frequencies which your phone stays at a lot when 1242 is your max.

Try one of the pre made setups and play with those settings! Or keep them as is, whatever you want to do

[T-Mobile Samsung Galaxy S 4] MENACE_69:
It may be a question with a obvious answer that has been addressed before I'm sure, and i think i already know the answer.i just want some clarification.

Is it best to stay with the settings of your likeing (example: superbull, dead by april ect.) for a couple days to see accurate battery statt results?

[T-Mobile Samsung Galaxy S 4] MavereXx:
Hey guys I have two new updates for my ktweaker setups for you today :)

~~**Super Bull 2.0**~~

Based upon a custom I/O scheduler configuration by [MENTION=5082757]LuigiBull23[/MENTION] from his "Balanced Bull" setup, Super Bull aims to achieve Amazing Battery Life at little/no perceivable cost to performance.

Thouroughly tested within the XDA community before release. Thank you to all the testers that really helped make this setup smooth for the majority of s4's :)

-Improved voltage stability and performance yet still considerable battery savings

- Highly optimized and fairly balanced CPU governor (ktoonservativeq based)

- Blazing fast read speeds without much loss to write with [MENTION=5082757]LuigiBull23[/MENTION] 's amazing ROW optimizations.

Download:

~~Super Battery Saver 2.0~~

When intense 3d gaming isn't important, and you want it so the only thing killing your battery is your screen, you need a profile similar to this.

Efficiently works with low frequencies to accomplish majority of tasks. Touchwiz is suprisingly smooth!

Sometimes ill forget I'm even using it!

Based upon my SB2.0 voltage set and governor but focused 100% on battery life. How long will it last you?

Enjoy =)

Loaded superbull 2.0. Just wondering why is auto hot plugging checked? I was under the impression that ktoonsevativeq was a hot plugging governor.
[T-Mobile Samsung Galaxy S 4] MavereXx:
It is, that's just a leftover from me playing around with other governors based upon the super bull profile. Doesn't do anything to this Profile whether its checked or unchecked.

Nothing beats ktoonsez' governor :)

[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Yes. I'd give it a minimum of 3 full cycles before you can truly determine more accurate results.

EDIT: The Shop has been updated with Super Bull 2.0 :D

Battery Performance will vary per user, depending on what apps you use some may poll higher frequency,lower etc. Also screen brightness,background running apps,how well the device go into deep sleep. It all makes a difference.
[T-Mobile Samsung Galaxy S 4] Jabberwockyyy:
The settings in the spoiler for Super Bull 2.0 don't match the settings in the downloaded file itself. For instance the screen off profile scheduler when restoring the settings is set to same as the selected scheduler whereas in the spoiler it is listed as noop. Just pointing it out as it might cause some confusion!
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Thanks. Must have missed that one while editing. It was a minor left over from previous versions. Nice catch :)
[T-Mobile Samsung Galaxy S 4] colorchange:
I am very pleased with SuperBull 2.0. It has been rock solid stable since early prototype and here is a screen shot. Standard battery, no noticeable lag for me after it settled in.

I see I've got to get my Google services under control.
[T-Mobile Samsung Galaxy S 4] manofcolombia:
Turn personalized ads off. And location off and you can just have the gps toggle in the notification shade if you needa use navigation. If your just leaving it on all the time then it's just sucking juice and allot of it. I had the same issue

Double check your wifi settings. If you go to advanced wifi settings and switch your wifi to sleep once your phone goes to sleep. Else it's staying on even if your phone is in deep sleep. So you can switch it to always on only when plugged in.
[T-Mobile Samsung Galaxy S 4] gandhidog:
I found this result interesting... After much tweaking, I decided to test stock settings. Interactive governor, no mhz or voltage changes, just stock everything. To be fair this was a day with light usage. Wifi on all day, and screen on time was only 3 hours but this battery life is great on its own. I'm really satisfied with performance too. Phone wakes quickly and everything is fluid.

Configuration changes

- way faster screen on when phonecall during CPU sleep, no lag :)

- CPU intensive apps now run perfectly :)

No more versions for a while this is as good as my settings gets until ktoonsez gives me some more stuff to play with =)

By far the best most stable version IMO

Ladies and Gents I present to you project Icarus which consist of 3 profiles I have been putting together and testing for weeks and now is finally here. I only tweaked each profile on a TW rom. I cannot guarantee same performance output on AOSP but you can always try it anyway as other tester useing AOSP rom reported good battery performance and stability.

My aim was only 2 profiles but I add the 3rd incase someone else besides myself can run it stable.

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

The download zip is to be extracted which contains a folder of all 3 profiles and a "Extra" folder of bonus item I randomly created on our Galaxy S4 ;)

Lastly I would like to thank the following :::

::

Ktoonsez - for provideing us with such a great custom kernel with features to tweak to our likeing an most of all have fun doing it.

LuigiBull23 - for createing this thread so that anyone like myself can openly share profiles and help each other to provide a better experience on our galaxy s4 running ktoonsez custom kernel.

Droidphile - for explaining Scheduler and suggestion in determining which would be suitable.

PiggySmalls502 - For testing and providing feedback on my tweaked profiles in order to work out the kinks and make it stable as possible. Thanks alot.

[T-Mobile Samsung Galaxy S 4] mamba720027:
Just an "OTA" folder. Like in screenshot. Just use rootexplorer app go to "system/apps" and delete ktweaker. Reboot into cw recovery and reflash kernel. Open ktweaker,reset defaults and reapply whatever profile you were useing.

If u have that in their then u shpuld be fine and dont need to do the above.

[T-Mobile Samsung Galaxy S 4] arcrox:
Are they different from the voltages used on SB2.1? Right now, I'm running 2.1 with the more aggressively tuned CPU voltages from 1.5-1.8, and Ktoonez's GPU voltages of -75mV (in light of the post made in the main Ktoonez thread a few days ago). Seems to work fine and is stable, but is there an underlying possibility of this actually having the reverse affect because the device has to "work" harder?
[T-Mobile Samsung Galaxy S 4] MavereXx:
I find the device seems to lag slightly if its undervolted *too much* (which means working harder or unable to work; my estimates: more than 40-50mv), even though they dont crash on most devices. But my voltages for 702mhz and below on superbull 2.1 are accurate default voltages samsung just put 900mV for 702mhz and below which is funny cause it doesnt need that much power to run 100% stable and fully operational when its running at such low frequencies.. but it seems nobody notices this when they configure their voltages. They keep 702 and below really high.

I'd pin the default stable voltage of 81mhz where you can drop it by -50mV and still be stable at 795mV (so 745mV is -50mV undervolting, my device personally can run stable at 715mV)

The next two frequency steps only need an extra 5mV each

[T-Mobile Samsung Galaxy S 4] CamFlawless:
Definitely not. You may want to wipe data for ktweaker. Or make sure you're not somehow bizarrely set to performance governor. :p
[T-Mobile Samsung Galaxy S 4] JaZart:
That didn't solve the issue. It seems the only way to circumvent the issue is to turn on power saving mode and check "limit cpu frequency". After doing that, the cpu behaves properly. However, I don't want to check that as I'm sure it has a noticeable impact on performance.
