Hi
Can some one help me , i will like to know witch should be the bes cpu settings?
my cel. only have as max1512mhz , and a freind told me that try to run as min less than 500 mhz.
But on the governor witch should i select interactive , conservative, ondemand, userspace, powersave, or performance?
and on Io scheduler noop , deadline , row or cfq ?
I am using [4.3.1] Official LiquidSmooth [Ver 2.25].
If someone can give me any info on this i will apreciate it.

nobody can tell you what the best is. what works best on mine, may not work best on yours. it depends on what kind of user you are.
I can only tell you what my settings are and how it works for me.
I always go 1 up from the bottom on min to 384
I set my max to 1512 usually, just because I don't want to redline my rpm's (car reference)
on liquid smooth, I had set my governor to Userspace to get rid of my wake problem.
my scheduler, I left it alone. I haven't noticed it do anything for me.
I am not hardcore user. I barely game or call. mostly text and my music along with XDA and Facebook. I will get all day with about 40% battery left. cause I charge every night, that's all I am worried about getting.
hope this helps

I have found explanations for most of the governors but would be nice to have a better explanation of the governors in particular the Smartass governor. Any kernel devs want to do a nice writeup explaining these.
Thanks.
the thing with governors is that they typically vary by developers and sometimes even by individual kernels. The concept of smartass is to throttle back when not used and ramp up using more slots to accurately match your speed to your usage. Most devs throw their own tweaks into each governor though, specifically the smartass one most
hope that helps a little bit...
Nice development thread!
This is more of a general question (and probably will rightfully be moved there soon enough)
Here it is though
Performance (never use): Keeps CPU at max all of the time
Powersave (never use):Keeps the CPU at min at all times
Conservative (personally suggested): Keeps CPU at lowest clockspeed possible while trying to perform well
interactive: Generally not used
smartass: works like conservative most of the time but locks the CPU at a low clock speed with screen off (depends on the kernel on exacts)
interactiveX: Seen in a kernel for my TB but NO idea what it does at all
Any I miss?
Userspace. Nobody knows what the hell its for.
Ondemand...lowers clock when not needed, ramps up very quickly when needed.
Interactive is very similar in that manner.
smartass can be configured to act like conservative or ondemand. I have it acting more like ondemand.
Standard Linux governors.
im running the extreme1.92x kernel oc'd at 1.4 but not sure about the best setup to save battery. i made one profile for charging i put in on max. not sure what to do with the advanced tab settings.
Profiles are really dependent on the user and their needs. The one piece of advice I can give you is to make sure you have a profile set up in case your phone starts to over heat. An OC'ed phone maxed during a charge may get quite toasty.
any suggestions?
Imo dont o/c. Let the kernel operate the way it is setup. O/c cause reboots, phone heating up, and freezes.

I'm running Adrynalyne's 4.4.7 kernel and use the following and get really good battery life with no overheating and no lag. I don't do a screen of profile because the governor seems to handle that pretty well.
Normal 1024 max 245 min-Smartass governor
Profiles:
Battery < 25% 768 max 245 min-On demand Governor
Charging 1280 Max 245 min-Smartass governor

Does that actually work?
I thought you had to choose a default governor and setup profiles accordingly.
I didn't know you could setup profiles with a governor that wasn't active or chosen on boot.
the thunderbolt is so fast already theres really no need to over clock. i left it at stock for normal, toned down to 768 when <30% battery and down to 368 when screen off. its a little slow for about half a second when waking up but the battery life is amazing. i can make it through a whole day without charging with moderate use. also running ziggys bfs kernel on virusrom and that added a ton of speed. way better than overclocking that drains your battery
im not asking about overclocking or profiles, just want to know about advanced settings. everything is set to default -1.

What Rom are you using?
Go to settings, menu, wireless networks, mobile networks and uncheck the third box. No need to have mobile data always on for most peeps . You'll still have 4G n everything, but gain a good 1-2 maybe more hrs (depending on use, kernels, governor settings, and I/O scheduling. I personally am running BAMF 1.6.2 with adryns 4.4.7 kernel, no set CPU, using tool box for that at 245mhz min - 1.024GHz max with ondemand governor and most importantly SIO Scheduler. Try these n you will have amazing performance and better battery life. Let me know you opinions

No matter how precise I click, I can't get SetCPU to set 1024mhz. Closest I can get is 1036. What gives? lol

Haha, I couldn't tell if you were being serious or not but each kernel has speeds at different increments. 1036 will probably be as close as you can get to 1024.

My settings are identical except running 1.6.3, what does the SIO scheduler do or any of the schedulers for that matter?

You can use Wikipedia for the scheduler info. Once you look into it you'll know why I didn't wanna type all those details in here from my phone. Lol, but yeah set that to SIO, Take off ENABLE data always on. N you should be better let me know.

Go to manage applications and clear data from set CPU and when u go back in to set CPU you will have to hit auto detect n if ur kernel has that frequency you'll be able to click it.

Can somebody please explain the SetCPU governors to me? Normally I would use Smartass V2, but we only have the stock kernel.
The main governors I am curious about are mot_hotplug and hotplug. My phone seems to use a lot of battery when these are enabled, even with underclocked minimum scaling values.
Last night I ran my phone on ondemand at 300 min -300max (screen off profile) and it didn't drop 10%, first increment on battery reading stock ROM). Today while in school, it dropped from about 80% - 20% (using the same profile but with mot_hotplug).
Do all of the other governors manage both processors and hotplug can not?
You might as well use hotplug m8

Why? That doesn't make any sense based from the findings I posted.
I'm using mot-hotplug in a week I'll know
Was using ondemand but I read an article where it shows the descriptions. Apparently hotplug behaves very similarly to ondemand but has the capability to turn off the 2nd core if there isn't a lot of workload. I switched to hotplug and so far its shown a significant difference in battery life. However, it may be a placebo as well so i'll stick to it for a week or so and then compare.

I use kholks custom CPU governor it seems to be a lot snappier and battery use is good.
There is info in the development forum on here about it and using it.

alright. ive been playing around and cant find some good governors for what i want.
for hardcore gaming, what governor have you found that works the best
for best batter saving, but still be able to watch videos, surf web, email and just general navigating without it being too slow.
which governors do you guys use for both of those? thanks

Use the smartassV2 governor. It regulates the CPU frequency according to load (sorta like ondemand except it works better).

i tried and i liked it, but it like locked my cpu at 1.24ghz (thats the max i have it set to) and even if i changed it, it would lock to the max frequency????

I'll have v1 of Funky kernel out soon if you want to try out wheatley.
I've been a fan of smartassV2 since the first time I used it on the Thunderbolt. It is as close to an ideal governor as I've ever used. SmartassV2, with a complete sysfs implementation, can be tweaked very nicely. It is a governor that you can really tune so that most of the time it's not running balls out, but it's not loafing along either, which is how a governor SHOULD function. (I like to see a nice bell curve peaking at an ideal frequency, and spiked way out at the bottom frequencies when I look at a bar chart of my time-in-state's.) From what I can tell, few if any devs tune their governors to their kernels. I'm thinking that's how we ended up with a dozen or so governors that are rather similar, yet rarely ideal.

Alright now my problem is that I set my CPU to 192mhz lowest and 1.24 max. And that's for normal use. I'm running smart ass2 Nd it's not licking my CPU at max anymore, but it keeps.moving the max to 1.51ghz.
any ideas on how to fix tht?

Yeah. Don't use DSB's kernel. I spent DAYS trying to figure out what his kernel is trying to do as far as governors. I'm not going to talk smack about the guy's work, but I will tell you what I know.
I doesn't appear any of the governors have been tweaked for his kernel. It looks like code was just tossed in there and left however someone else wrote it. For instance, smartassV2 has a sleep_wakup_freq of .998GHz, which is much slower than it should be. It SHOULD be near or equal to scaling_max_freq. Likewise, the max_cpu_load (which determines when the cpu should scale up) is 70, a fairly aggressive number, while the awake_ideal_freq and sleep_ideal_freq are pointlessly high. If I had to guess, these look like parameters for a Snapdragon S1 SoC, not the dual core S3 the Rezound has. No matter what governor you choose, it's only active on "cpu0". "cpu1" runs ondemand no matter what. The reason you have trouble making settings for the governor stick is because the sysfs location disappears and reappears for no obvious reason. It appears when things pop in and out (presumably when cpu1 goes on and off line), things are reset.
Cold hard reality is this: You're NEVER going to optimize any kernel out there to it's fullest potential. Either the options aren't there to tweak, or they behave in inexplicable ways. I can't tell you why DSB's kernel (not to single out a dev or his work, but I'm certain that's the kernel you're talking about) does what it does, but it's so far divorced from optimized on such basic levels you're better off not wasting your time.
As an aside:
After getting a rough feel for what some of these kernels are doing, I'm not at all surprised some kernels have had significant heat and battery drain issues. There are things that simply do not work right or work consistently. The devs shouldn't be blamed for this. These are probably the issues they're trying to work around that they inherited from the sources they're starting from and what makes tweaking them so difficult.
I acutely got everything to work. I'm just trying to overclock the GPU.

If your running performance governor your cpu runs at Max Freq so battery is going to be terrible plus the fact you have high usage,
please give more detail like rom kernel etc if you use task killers or greenify, ram managers
Other things like gaming

Try using OnDemand governor and if you have it use nightmare governor as its performance based
and see how battery is also try wiping battery stats in recovery after full charge

pegasusq, LionHeart, SmartassV2 are good governors try to balance performance and battery.
row and noop are good schedulers, but sio performs better in dual core processors.
