What do you mean? You want to over- or underclock or stay at one frequency?

they all do. it only will go to max frequency when it needs to, otherwise it stays below. you can always set max frequency as max and as min, then itll stay only at max cpu speed.

For example, when the Antutu cpu decreases the frequency of max. less.

Hi,
Thermal throttling.
If I understand right...

right. thats thermal throttle kicking in. if you have root, you can disable throttling, or you can always cool down your phone in a freezer before running antutu.

Let's OC

It's time to Overclock our Phone...
DISCLAIMER: OVERCLOCK IS DANGEROUS FOR OUR PHONES
How to:
1. Now download r151 from Here
2. Put the files of r151 in the root of SD, run HARET.
3. Download SetCPU from Here and install It.
4. Now open SetCPU, And choice "Autodetect Speeds Reccomanded".
5. Allow Root.
6. Press Windows button and choice "Perflock Disabler" and "Attemp to Disable Perflock" and Check "Set on Boot".
7. Now, close the windows and OC our Phone.
My phone under USB and AC run at 825 MHz without Crash, i had tryed to run it at 864 MHz but System Crash everytime. Without USB and AC my phone run at 787 MHz. I Post 2 Images 1. = Normal Clock 2. = 825 MHz Clock.
To Made Benchmark i Use BenchmarkPi.
1. Screen Normal Clock
2. Screen 825MHz
For Other Question:
1. SetCPU
2. -r0bin-'s Post
I did it, it works perferctly !
Upscaled to 825 and min 128
Downscaled to 245 while charging and screen off
Thanks !

My Profiles:
1. Screen Off Min: 19 MHz Max: 245 MHz
2. In Call: Min: 128 MHz Max: 600 MHz
3. Charging AC: Min: 19 MHz Max: 825 MHz
4. Charging USb: Min: 19 MHz Max: 825 MHz
5. Main Profile: Min: 19 MHz Max: 787 MHz

Tell me please, does it helps to save the battery in last releace (r163)? I`m asking becouse i try to use Master CPU, and it seems to me that it don`t helps to save energy... But I don`t use profiles, only ondemand settings from 120-600 mHz.
Thanks!
@HTCxxxx
what is the percentage priority by profile?

To PowerSave try 19-480 MHz if Don't need Performance or 19-600 MHz Im Sorry But i Don't Know Master Cpu

19 Mhz does not work for me. Phone gets unusable slow and dont come back :/
Beside that, underclocking do not have a big influence on the battery consumtion.
Undervolting would be more interesting.

Why Unusable??? Yhea, Undervolting can be an Interesting Thing, but i Think if the Volting is too low phone Freeze, and if is too high cpu can have an High temperature if you're stressing cpu and phone can freeze too. But i've noted, when i use a low "screen off" profile battery consumaption is high? why? is a problem of kernel? or is nomal?

you are right,i also experienced that 19 Mhz makes phone lazy
i'm also agree about 2nd part..i read the same

you don't need to undervolt it too low,you just need to find the right voltage
try last kernel from r0bin and you will not have high battery consumption anymore
Low Mhz does not lead automaticly to low consumtion.
If you phone has something todo (update something for example) it will get the job done faster with high Mhz and is going fastert to sleep after that.
With low Mhz it takes longer and so can have higher consumtion.
On my HD2 I dont use profiles (like screen off) and it has a very low consumtion on standby/sleep.
If you set a minimum speed when screen is off a11 is not able to go to suspend, maybe
just a quick feedback on power consumption:
it never been so good with r167+drain fix without SetCPU
when I set profiles with low frequency (19 or 128Mhz) it keeps on consuming battery up to 100mA. when i switch SetCPU profiles off, i go to 9mA in suspend mode.
true story
there must be a way to setup SetCPU in a way it doesnt affect too much battery drain in suspend mode, but for the time being i just deactivated it.

(I THINK)
Hi All,
I've understood why CPU doesn't run @ 19MHz or @ 128 MHz...
Go to /sys/acpucloclock and look acpuclk_tbl...In It there are write all frequencies CPU can Run:
245760,400000,480000,600000,768000,787200,806400,825600,844800,864000....
but no Under 245 MHz so if You use a Profile for Screen off From 19MHz to 254MHz, cpu Run everytime @ 245MHz...so there is an high consummation of energy
bye

hi
as codiak said earlier lowering CPU(underclocking) doesn't have so much impact on battery life..he also explained you why..if you want i will explain you too
explanation:run CPU at low voltage,open an app or downloading an email,etc= CPU will take time to get to the level app needs,display will stay longer while it CPU will get done the job= worse battery life
Undervolting will have impact on battery life
explanation:run same CPU clock at lower Voltage= CPU will use less power=better battery life
hope it's clear enough for you now,and if anyone else thinks i'm wrong feel free to prove me i'm wrong
P.S. Anyway i asked devs and they will lower CPU to run @ less than 245 Mhz.
Enjoy

SetCPU modes?

What does it mean ondemand, performance, hotplug and so on? what is the diference?

Well, ondemand : cpu maxes only when is needed
performance: cpu runs always on max speed,and consumes lots of battery...
I don't know anything about hotplug
hotplug
Hotplug its the performence switching all the time like if u put it on 200mhz and 1000mhz it will be like this: 1000-200-1000-200-1000-200-1000-200
its switching every 1sec
This means a lot battery consumption, right?

Ya..hotplug using apparent juice aiming good performance side..if u want no compramis on battery choose ondemand..u can also use 'setxperia'(free from play store) by intek which working awsom on o3d..

[Q] CPU Question

Greetings people!
Sorry if this was already asked, but i couldnt find answer anywhere.
i ve rooted nexus 5 (stock kernel, stock rom) and installed trikster mod. I have noticed that minimum and maximum cpu frequencies are changing from time to time. Is this normal?
Thanks!
Hi,
If the min CPU freq changed by itself it could be due to MpDecision (the min CPU freq is increased for smoothness purpose when you touch the screen so when you open Trickster Mod for example for xx ms... plus the specific refresh time of the app to see the real min CPU freq), for the max CPU freq maybe due to thermal throttling at some point (the CPU freq is decreased according to the CPU temperature to avoid damages)...
What is the min CPU freq when it's changed? 1.26 Ghz?
What is the max CPU freq when it's changed? In what situations?

Nexus 5 permanently slower after overclock??

I'm pretty new to Android. I got my N5 2 months ago and rooted it as soon as I took it out of the box to get rid of the navigation bar. Didnt install any ROM or kernal.
What I did today was try to overclock it. I wanted to test the performance upgrade with Geekbench 3.
I got 2500. Tried to overclock with this app called: No-frills CPU control. And suddenly I get no higher than 2000...... Tried everything. I'm stuck at a multi core score of 2000 in geekbench while it should be 2500>.
WTF DO I DO? My device is noticeably slower, it's like a GS4 D: I'd rather not install any kernals/Roms
I set the minimum CPU frequency to 300Mhz and max to 2.266Ghz
Hi,
Thermal throttling..., overclocking produces more heat than the stock CPU freq so more thermal throttling. To prevent any damage, the CPU freq decreases according to the CPU temperature...
Let cool down your phone.

Sure, I'll turn it off for a while.
Just to make sure: the standard CPU frequencies are 300Mhz MIN and 2.266Ghz MAX, right?

Yes, that's right 300 Mhz-2,26 Ghz.
Not necessary to turn your phone OFF , when it boots it's a process that causes "heat" at the beginning then you will need to let it cool down again. EDIT: oups, you mean the thermal throttling OFF maybe?
Don't touch it for a while, airplane mode can help. If you are in a "hot" country/weather, air cooling, fridge...

I've let it cool down and I got my old performance back . Never knew the solution would be so simple. Thanks.

CPU frequency scaling

Something is boosting LITTLE cores to 1248MHz even with 10% load. Messing with governor and kernel adiutor settings doesn't help. Even in powersave it does the same when I touch the screen. This seems inefficient and not battery/heat friendly to me and the only reason I can think behind this is to make big cores less active. How i can disable it?

Even in powersafe?? Powersafe should never change the frequency since maxFreq is minFreq.

Yes, even in powersave minimum freq jumps to 1248 when I scroll.

I think maybe it's like a touch boost option that made the scrolling lag free, so many custom kernel have it, xiaomi could have implemented something similar
