[Q] MIUI Set CPU settings

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.

Kernel for mik3d??

I'm currently running mik3d and in my opinion its the best 3.0 rom out there at the moment. But what's the benefit of using a kernel other than stock? And any suggestions for kernels and how do I flash a custom kernel? Thanks in advance

I am running MikG (not 3D) but I can address the reasons for running a custom kernel.
- Overclocking: Custom kernels will often allow you to change the max cpu clock to improve performance when you need it.
- Underclock: They also allow you to lower the max clock and the min clock if your aim is to try and improve battery life.
- More Governors to choose from: They will often have other cpu clock governors that can be used to balance battery life vs performance (see here).
- Undervolting: Some kernels will use various schemes to undervolt the CPU as another means to save power.
- HDMI Mirroring: The stock kernel will output a display to the HDMI only from the photo gallery app. The custom kernels can allow full display mirroring to the HDMI. This allows games, netflix, etc to be viewed on the big screen.
- Memory optimizations
There may be more reasons... these are the one from the top of my head.
You flash a kernel much the same way as you do a ROM. From Recovery you would wipe Cache and Dalvik Cache before flashing the ZIP of the kernel. That is it. Some kernels then allow adjustment with programs such as SetCPU.
There are a few kernels that support Gingerbread Sense roms (such as Mik 3D). You can look at Freedom, ChopSuey, Golden Monkey, Poonsense. I am running Freedom and it works well for me.

I just tried adjusting my CPU after installing freedom and my phone froze lol

Some phones do not like to be overclocked. That is normal. You just have to find out what your limits are. Mine actually does not like to be run as low as 128Mhz. When I do that I get boot loops once in a while.

Undervolt gNex w/franco

I tried searching but didn't turn up anything..
I'm running AOKP milestone 4 and Franco'a kernel.
I'd like to undervolt it because I've got plenty of performance and undervolting did wonders for battery life on my old OG Droid.
I know I saw controls for the voltages the other day but I can't find them to save my life now.
Help?

SetCPU or Franco's Kernel Updater app
Sent from my Galaxy Nexus using Tapatalk

franco's kernel update and setcpu were the first place I looked but no love.
Didn't find anything promising in setcpu .
franco has a OC/UV tab which sounded promising but is only showing over clock stuff. the Calibrated Voltages tab sounded good too but seems to be read only for me (and I am su).
Also tried jrummy's Android Overclock. No joy there either.
I KNOW I saw it somewhere the other day!

your phone is rooted right?

Yep, rooted as soon as I got it.

I'm also running the same set up as you.
my voltage setting are located under :
Settings -> ROM Control -> Performance -> Voltage Control
Hope this helps

Curioser & curiuoser... ROM Control was the first place I looked today and is definitely where I think I saw it the other day.
But now I only have two sections under Performance: "SET CPU" and "FREE MEMORY".
The SET CPU section has "Max CPU", "Min CPU", "Scaling governor" and "Set at boot" but nothing about voltages.
I'm beginning to feel like I've fallen down a rabbit hole!

Did you mod anything? It should be located there...
Here is a screenshot of my performance menu, it's German but it figures
The menu points are Max CPU, Min CPU, Governor, Set on Boot and Voltage Control, running M4 and Franco...

i think voltages only show up if you're rooted and your kernel supports it.

Well he has written already that he is rooted and Franco Kernel deffo supports it...

But he might not. I thought was rooted one time before and ended up i wasn't. Others have done this before also.

Yes. Some versions of franco kernel disabled the undervolt feature. Make sure you flash the latest nightly (110 at the time of writing) and check the options in the franco updater app. You should see the Undervolt option.

Mystery solved!
V6 Supercharger was the culprit. This phone runs so well I probably don't need that anyway. Just ran it out of habit, I suppose.
Unfortunately I didn't notice this for a week and running the uninstall doesn't restore the voltage controls. I'll have to restore back to there and then redo all my changes for the past week manually. Oh well..

Voltage Control

Installed it but dont have the voltages tab like on my SGT. Only available tabs are General, Device Info and About.
Do I need to do anything else for it to give the voltages adjustment options?

Are you using a custom kernel? Stock kernel doesn't allow voltage or clock control.
Personally I am using Perseus kernel (by AndreiLux) , it comes with STweaks which allow you to control a wide range of settings : voltages, CPU and GPU clocks, governors, audio tweaks.. and it closes the recently discovered exynos exploit.

I guess that is the reason! I am on stock kernel.
Any other kernel suggestions? I am quite quite happy with my note performance in almost every way so wanted to play with voltages for curiosity reason only. If I flash a custom kernel I still want to maintain the stability of stock without need for any fancy stuff.

I am a happy camper with RedPill v1.0. But this surely depends on your personal taste, there are quite a few others as well.

Best CPU Tweaking App/Optimal Settings

Hey so I was just wondering what everyone thinks the best CPU tweaking app is, and what you believe the optimal settings (such as speed, governor, and scheduler) are.
It's been a couple years since I've used an android device, but I've previously used SetCPU. Is that still the 'king' of CPU management or has some other app emerged?
In a nutshell, post your ROM/Kernel, favorite CPU tweaking app, favorite settings, and why you chose them.
Here's mine:
ROM: Stock
Kernel: Stock
App: SetCPU
Settings: 1512 MAX, 1026 MIN, ONDEMAND/CFQ
Why: Don't know any better options
Let's see what we can find out!

ROM: PA
Kernel: Faux
App: Fauxclock (trickster mod is a free one that works really really well)
Settings: 1512 Max, 160 Min, Intellidemand/Fiops
Why: PA so I can customize and faux cause I used his kernel for S3 and it gave me awesome battery life, and N7 is no exception to that! I went 1 day with 3 hour screen usage and only lost 35%.

ROM: ParanoidAndroid
Kernel: ElementalX
App: ElementalX uses Aroma installer to customize features
Settings: 1728 MAX, 1026 MIN, ONDEMAND I think
Why: Not sure what you expect me to say. These were the settings I used on my Nexus 7 before I returned it and ordered a new one from BestBuy. I plan on using the same setup when I get my new one.

These are my settings memory settings below

Kernel Tuner is a nice app for adjusting everything on your tablet. It allows you to adjust each core individually, or link them all together! I used SetCPU as my primary CPU tweaking tool for years, I guess since I first started flashing kernels on my OG Evo (Evo 4G, Wimax), but find Kernel Tuner to be much better!! Adjusting each core individually isn't something that SetCPU allows you to do, plus there are many other features in Kernel Tuner that aren't available in SetCPU. Ever since someone referred me to Kernel Tuner a while back, it's been my go-to CPU tool!! Anyone who hasn't used it before should DEFINITELY check it out, I think you'll like what you find in the app!!
SwiftKey'ed from my '13 Nexus 7 FHD using XDA Premium HD

im on elementalX 1.4 using trickster mod donate version, overclock at 1.8ghz but i under clock and undervolt with trickster app
if u don't play games, don't bother o/c, underlock to like 1.1ghz and improve battery life! i think 1.1 adds at least 1 hr SOT

Stock kernel isn't real customizable at all. You need a custom kernel. I recommend faux but everyone will say the one they use is the best so flash around use one for a couple days and move on until you find the one you like.

As far as I know, Faux plus the faux app are the only way to get the screen color balanced.
worth the price of admission right there.
And definitely turn your minimum clock down to the lowest it can be - idling at 1 ghz as you do at default is pretty pointless.
Add greenify and better battery stats to the mix to address apps that keep your device awake for no good reason, too.

"Faux123 Kernel Enhancement Pro" aka faux clock includes color tuning. Second or third to last page of the tunables in that app.
