Since ktoonsez lets you choose from a myriad of CPU governors and IO tweaks. Since their are so many and i for one have not found a list that explains every option this kernel offers.
So i am asking what you use if you do? and what do you think about the ones i use for my Daily Driver setting, I play games lightly I steam audio frequently and want good battery life (if it lasts all day with maybe 3-4 hours screen time) and can still run most games i am happy. So far With my Current Settings its been good to me although i have yet to put it though some heavy use.
For CPU governor I use "Scary"
ans i use the "vr" IO tweaks
I have similar usage habits as you do, however I don't use KT's kernel. I am using LeanKernel and am easily getting a full day's battery with nearly always 4hrs of screen on time. For me, since I am working on something atm and flashing a lot lately, I use Interactive/SIO as it has always been good to me. I know there are plenty of other Gov/Schs out there and I will settle on one (once I settle on a ROM for more than a week-lol).
Anyways, if you want to read more about Governors and Schedulers, you can go here and click the Hide parses to give you a bit more info.

Whats up guys? I have a question about using the Set CPU app.
Is it really worth it to use this app? Will it actually make an improvement in my battery life?
I don't want to use this app to speed up my phone, but to make it better on battery life.
I know you can set up profiles, but I'm not sure on what good setting would be to use. Can anyone give me some insight on this?
Also I'm running the latest version on MIUI and the Tiamat kernel.
P.S. Is there better kernels to be used then Tiamat?
Thanks in advance.
also I'm running the latest version on MIUI and the Tiamat kernel.

maybe it's just me, but am getting better bat life with the stock kernal. I ran the tiamat for a few days, switched back and it was obvious to me.
With Tiamat the default governor is smartass, which has a built in setting for when the screen is off, that only lets the phone see a max of 368640, which will save on battery life and does.
Now if you want to get into using your own profiles then an app such as Setcpu can be helpful.
I have been using this and this in place of Setcpu. It's a little faster reacting to the changes form screen off to on. Just another option.
I like the Tiamat Kernels as well as JD's Kernels. They both work well with Miui, at least on my phone anyway.
I've used Set CPU for awhile, but then got away from it. I'm back on it now since MIUI doesn't have a built in OC. I would try the two PacerguyDon suggested. I have used the andrev_oc it is fine. The second one appears to have more functions than Set CPU. Set CPU doesn't allow you to under volt if that is what you are looking for.
I saw that Set CPU is $0.99 on Amazon, if you want it. However, I would try the other two for free and donate to the one you like best.
I have been using JD's Kernel the last few days and it seems to provide better battery life than stock. I originally tried using the Smartass govenor, but had to go back to On Demand. The Smartass was causing screen wake delay when receiving a call.
I stole this from another PacerguyDon's post and it breaks down the different govenors found in most OC apps.
Govenors
Set CPU is free for XDA members. It also does allow undervolting according to their post.

Rooted Stock ROM. http://forum.xda-developers.com/showthread.php?t=2387942. Havent changed my Kernal asfar as I know, but have adjusted CPU setting in ROM toolbox.
I currently use OnDemand governor with max slider at 1200Mhz. After learning that OnDemand is not too good for batterys life long term as I use my phone in short bursts and alot of multitasking I have found that SmartassV2 would probably be the best governor for to use. The phone is used to play media, games, browsing and sketchbook app, nothing too serious but I want the best balance between battery life and performance possible.
I understand playing with the kernal can result in issues but have not managed to find a guide on how to do this on XDA. Can anyone advise me on this or point me towards a simple guide please.
Thanks.
so ur using Stock Samsung kernel with ondemand ??
only governor on stock kernel that have cores hot plugging is pegausuQ AFAIK so ondemand will cause worse battery
I have been using Omega Rom from version 8 up to version 18, then switched to ProBam, then Pacman, and now I'm back on Omega 19, giving the "official" 4.3 a shot.
I have tried many many settings and kernels to get this game run without a lag.
So far, I have seen no lag when using performance governor while playing for a few minutes (no overclocking the CPU or GPU) that was it...
Every other setup gives lag, more or less. The second best setup would be pegasusq governor, not much changes when overclocking CPU or GPU, or both.
Using a stock kernel is also not bad, but lags every now and then. (not dependant on Rom)
But I want to get the sound settings from trickster mod for example, so I feel like I need a custom kernel with my Rom of choice.
So, does anyone have a good setup that matches performance governor, but does not stick permanently to maximum CPU load?
I don't care about battery life, so I need a good performing setup.
(Just on a side note: when people say "there is no lag at all when scrolling through my homescreens" then I can only think that this should be normal with ANY setup. And I never had any lag while scrolling through my homescreens, except while I was using my HTC Hero...)
I would very much appreciate if someone with the same goal could help me out, or someone knows the default settings of the stock kernel...
Or is this whole idea just utopic, because the game is badly coded?
Hi. I just want to know how can I save more battery on this rom, cm cause when I had the TouchWiz stock one, battery lasted about 7-8 hours, with heavy use. And now with CM10.2 it only lasts about 5-6 hours, same use. How can I set the governor or which are the best performance settings for this rom? Right now I'm using interactive governor. Also, is it normal to take about 1 minute for the phone to boot? I have foldermount installed, but I don't know if it's the cause of this. Thanks.

I use the Slimrom myself, so not sure about CM, but 1min I think is a bit too long for the S4 mini. You may also want to try a customer kernel: http://forum.xda-developers.com/showthread.php?t=2568479 by F4k, its pretty good and stable. As for the governor, it situation dependent, some may perform better than the other depends on your installation and kernel. Generally ondemend, interactive and smartassV2 are pretty balanced between power saving and performance. There's few app you can use to set governor, its a basic function and they all work: https://play.google.com/store/search?q=kernel tuning&c=apps&hl=en
I don't use foldermount, but those type of APP do use quite a bit of process, especially now a SD card is involved. You can use: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en or similar program to monitor and see which process/program consume the most power.
Standard tweak are simple, disable unwanted radio, use the 'black/dark' version of the menu, don't use over-complex launcher, etc. I'm not sure if CM has the KSM feature (Kernel SamePage Merging) in the settings menu, if you do and happen to use it, disable it. It waste about 30% of the power.
No need for anything fancy. Ondemand governor is the usual "standard" and gives me great battery. Smartass has always been awful on devices ive tried it. make sure you don't have programs like Facebook running in the background. Most likely its an app causing your drain.
I use Elementalx custom kernel. All the things in its app confuse me. The only thing I understand is setting min and max CPU rates. I did a lot of searches on what everything else is and what to do with it, and nothing made sense. I need an explanation in layman's terms. Any help would be infinitely appreciated. My device stutters a lot and I don't get very good battery life.
You can take a look at this thread

There are a lot of basics and information.
I run EX too and leave the default settings as is. Flar knows more than me that's for sure!

Just leave the default settings as they are. The kernel devs know what they do.
I would recommend testing all kernels and choose the one that fits for you and your usage.
For me mvk is the best but I know people were mvk is not fitting their usage and they swear on francos or elemental or....
Test them all and find the best for you.
I usually turn off zram as this phone has so much ram it didn't seem to need it. Had no noticable issues or anything.
I thought leaving everything at default is the best thing possible for this phone, at least Flar said to not use any other governor other than default sched anyway. Phone is smooth enough for me to not tweak anything anyway. That was the point for buying this phone at first place, leave Google to do their optimisation and sorts so we can simply start using it and save time.
Use the "L speed" app by paget96 in the playstore.
