Cpu settings

Has anyone noticed that the cpu throttles based on its current stress level.
Sent from my HTC Liberty using XDA App

That's deff interesting. I haven't done much playing with CPU apps because the one time I put setCPU on my Aria it caused all kinds of issues. But that was like three days after the Aria launched so setCPU may support Aria now.

According to Android System Info I get:
480mhz 23.08%
600mhz 76.92%
So it is throttling for sure.
Maybe SetCPU will work now? but I hope it can throttle lower than 480. is there a limit to how low it can go?

All phones throttle in order to save juice. Your phone wouldn't last long at 600mhz. So this won't help with setcpu since the kernel still needs to be hacked. The CPU should clock lower in full sleep mode

It can, my Aria shows it is at 245.76Mhz 95.61% of the time
Android system info shows lower clocks, like 200Mhz, but my Aria hasn't operated at that speed at all.

That is when your phone is at full sleep. You won't see that speed when the screen is on.

Okay this makes sense then since it was a fresh install and I had yet to put it to bed

CPU problems

hi i just recently traded for a vibrant and when i got it it was already rooted. but it seems to have some troubles with the cpu. on set cpu it keeps fluxuating from 1000Mhz to 800Mhz to 1ooMhz and i think its causing my phone to lag a lot. anyone have any idea how to fix this or whats causing it to lag? thanks

The phone does that according to the load put on the cpu... If you set your defaults to 1000/1000 it won't do that anymore but will eat battery..
Sent from my SGH-T959 using XDA App

i set both to 1000 and it still goes to 100mhz

Solution: stop messing with it. The clock is supposed to do that.
Sent from my SGH-T959 using XDA App

yeah its variable clock speed...let it keep doing what its doing...

You can lock it to 1000Mhz, but your battery will last aproximately 1-2 hours. Maybe 3 if you're lucky lol. I wouldn't recommend it. The phone automatically goes to 1Ghz when it needs to.

I am not sure how true this statement is. Have you tried this? I have had my min clock speed set to 800mhz for about a week and a half now and my phone lasts me from 7am until 12pm without charging the battery with plenty of usage.

Undervolting?

I do it on my laptop, was wondering if I can do it on my phone to save power?
I looked aound a bit and everyone seems vey focused on overcloking. I don't have a problem with the 1Ghz speed, was ust wondering if I can stay at that speed and save some juice and if it' safe.

Yes you can. Get one of the apps off the market either unstable apps or jrummy. I use the unstable version to under clock from stock down to values of 50, 43, 36, 25. Which is quite a lot lower I think.

The apps are only .99 -so you can't go wrong with 'em. But I like learning this stuff and tinkering. So you may have already checked out this thread...
http://forum.xda-developers.com/showthread.php?t=812749
It is about overclocking- but you can use the same information to underclock. You just need the overclock.ko file and then adjust the setscaling.sh file so that it uses lower vsels.
I did a little write up in that thread...
http://forum.xda-developers.com/showpost.php?p=8771591&postcount=43
so if you want to check into- once you fool around with it a bit- it is not that hard. I now actually have 3 scripts I can run. 1 for stock clock speeds undervolted. 1 for stock speed stock voltage. and 1 for high voltage clocked to 1.3mhz.
good luck.

it has definitely been a great mod to my phone. I'm running stock speeds and ULV. Battery life has been phenomenal.

Care to post the file you are using?

The stock vsel is 56, right? I've tried going down to 54 and the stress test in set CPU goes well for 5 minutes. At some point between 5 and 10 minutes I get an error.
Is that normal and I should go with 54 or should the test last a lot longer without an error? Or is the stock vsel higher?

58, 44, 33, 27 are my vsel values oc'd to 1.125. Any higher oc will slow me down to a crawl.
To answer your question, I think stock vsel is 62 on Froyo.

I have been running the Ultra low voltage 1.3ghz preset from jrummy's app for a couple of weeks now with zero stability problems. Improved my battery by about 15-20 percent. I have seen warnings about stability with ultra low voltage but I guess I got lucky. Low 18's in Linpack and upper 1600 quadrants.

@aggie12 Care to share your vsel numbers? Im doing the same stock cpu speed just undervolted but I have hardly noticed a difference in battery life. How many hrs does your phone last in average use?

I typically get 36 hours before I get nervous at 20%. This is without juice defender, just straight 1ghz use on regular battery manager

How is 36s hours even possible? I get around 10-12 hours of use, but I'm a heavy phone user...
Also, is it possible to undervolt using setCPU?

No- set cpu only adjust your clock speeds- not the amount of power the phone is drawing to obtain those speeds. The .99 apps will allow for undervolting though. Or if you do a little study on the OverClock thread- it is not to hard to do with a script.

@Daali What are your vsel numbers? Mine are:
1ghz/45vsel
800/40
600/30
300/18
I get only 12 hrs of heavy use.

^^ siphen^^i just set this i'll start my test 2/marrow after I unplug for the day. I have extended battery mild user mainly txt/mms/no more than 30 min a day calling but i do surf sites quite often and wifi is on 24/7 as I have it at work and home> i'll let you know how those work for me.

[TWEAK][Siyah Kernel 4.1.1+][Extweaks] Get up to 7 hours of screen usage

WARNING: Use this settings at your own risk. I am not responsible for what will happen to your phone.
So, Siyah Kernel 4.1.4 has been released, and since 4.1.1 and its new features I have struggled for obtaining maximum battery life without loosing smoothness.
I tested these settings on 5 phones (Galaxy S2 GT-I9100): mine and my friends' ones, and we all got the same (more or less) results: it's awesome!
Screen usage can get up to 7 hours. I did these tests with mobile data on for all phone usage, and not in deep sleep. When I was at home I switched to Wi-fi.
My ROM is AOKP M6 (ICS 4.0.4), other tests were made on Resurrection remix JB, stock XWLPF (ics), CM9 stable (screen usage: about 6 hours, no more), and AOKP JB (latest).
Extweaks settings:
CPU:
GENTLE FAIR SLEEPERS: ON
CPU HOTPLUG: (default)
CFS TWEAKS: Linux kernel defaults
CPU IDLE MODE: AFTR+LPA
SMOOTH SCALING LEVEL: 800 mHz
MAX CPU LOCK: Dual core mode
CPU UNDERVOLTING: - 50mV (if you get freezes, set -25mV)
CPU STEP COUNT: 16 (all available)
GOVERNOR: pegasusq
MAX FREQ: 1200 MHz
MIN FREQ: 200 MHz
GPU:
MALI TOUCH BOOST LEVEL: Step 2/Step 3
GPU STEP 1: 44 MHz
GPU STEP 2: 66 MHz
GPU STEP 3: 100 MHz
GPU STEP 4: 200 MHz
GPU VOLTAGE LEVEL 1, 2 AND 3: 800 mV
GPU VOLTAGE LEVEL 4: 950 mV
THRESHOLDS: default values
AUDIO:
HEADPHONE AMPLIFIER: 0 (set this value as you want and as you ears can stand it, it doesn't affect battery life unless you listen to music)
SCREEN:
TOUCHMOVE SENSITIVITY: 3 pixel
ALL OTHER SETTINGS: default values
mDNIe negative toggle: off
BLN:
BLN: off
NOTIFICATION TIMEOUT: never timeout
BLN EFFECT: set what you want, cause BLN is disabled
LED TIMEOUT: use ROM defaults
LED FADEOUT: on
LEDS ON WITH TOUCH: off
LED VOLTAGE LEVEL: 2700 mV (2750/2800 mV if led lights are dim)
MISC:
ANDROID LOGGER: off
DEFAULT I/O SCHEDULER: cfq/noop
ALL OTHER SETTINGS: default values
I think they are not too aggressive values, but if you get freezes, I recommend you reset your extweaks settings via CWM recovery and then use less aggressive ones.
In the attached screenshots, battery stats analysis starts from 91% since I had to restart my phone, and when it was at 10% I plugged the USB cable in to transfer a .zip file in my SD card, but I don't think that this 15-second charge affected my test (I'm sure it didn't!).
Phone usage was high today, I used Tapatalk, created a new UCCW skin, did some long phone calls, Facebook, messaging, e-mail checking, and other stuff I don't remember since the battery stats don't even report them (lol).
Notice that this is an extreme test. 7 hours of screen usage is not a myth, reality instead, but you cannot get them with the so called 'everyday usage'.
Screenshots of test made on my usual phone usage will come soon

I think you forgot the most important part : the extended battery

Extended battery? so what we can get on normal? 4h?

I have a 1650 mAh battery... never had extended 2000 mAh

I don't think these settings are good for performance... I have used even higher settings and there was lagg in some cases. But that was all on my phone

This seems largely similar to my MagicConfig thread.

7 hrs screen time with 1200mhz max frequency and stock battery.. how much more if it's set on 800mhz.. 8-9 hours probably on stock batt?
you could have atleast included what you were doing in those 7 hours screen time like browsing, texting, facebook, etc, also the brightness of the screen, battery chart..

As you said, it was all on your phone. This is why with someone's settings nobody get exactly the same results: I get lags, you don't get lags, but he sometimes gets lags and sometimes not

MagicConfig was my starting point for GPU voltage levels, how cannot I admit? I always used those frequency steps (first post) but I've never found the right voltages to avoid lags, especially when turning screen on. And I forgot to thank you. I say sorry mate

@Adam Hui sorry if I can't help you, but I don't have a RIL matching the XXKH3 modem. I have XXLPW, and since it is all going well with it (deep sleep is ok, wakelocks are ok [more or less]) I didn't much care about it

Try GetRIL

Try the GetRIL app, it should be able to find the RIL for you.
But if I understand correctly, KH3 is a Modem from the GB firmwares, and you're running and ICS Firmware, the RIL is part of the Firmware and I don't think you can install a GB RIL on ICS... but try the app.

Need to test this. The magic config thread was slightly outdated and with new Siyah v4+ releases, it never got updated.

As I have mentioned before I do not possess an s2 anymore so it makes the process of updates slower. Doesn't hurt to be a bit patient right?

I configured my phone with your settings and it's running nice.
I can't really feel a difference in "smoothness" and it's the first time I change GPU frequencies and UV... but I still can't really tell a difference... what should I expect from changing GPU params, other than battery life?

buddy i cant find Siyah Kernel 4.1.1+ do you have any dwonlad that.

Annoying issue with core scaling...

I know many will probably just ignore this bug, but I can't because just knowing it's there is pestering. Anyway the GPU is not functioning properly ever since 4.2.2 . Its frequency isn't dynamic.
I would like if some volunteers with faux clock or another GPU reading app could confirm if they have the same issue on 4.2.2 .

Default governor for GPU is ondemand, it's behaving properly.

On demand doesn't entail a static frequency. Previously it would drop to 128 or 200 but now it sticks to 400... That is definitely not normal behavior for this governor. I only had faux clock open and I doubt that app would be GPU intensive.
And this is a problem for me because the the back is noticeably warmer than before despite me having a max of 1ghz and eco mode.

Ah ok sorry, thought you meant it wasn't scaling through the frequencies on light loads.
Dunno may be it's using some kind of low power state instead, I'm using faux stock enhanced kernel and mine is cool at the back with just normal use, also getting great battery life.
Mine only gets hot with heavy gaming or by just browsing with 3g on.

My issue is that it sticks to 400 which is high state. The only time it changes is when I set it to 487, it'll switch between 487-->400 constantly. Something is triggering a load but these tests are on fresh installs. It's generating heat which isn't good for batteries, especially non removable.
All these issues with my nexus are seriously making me reconsider my purchase -_-
