Well, there isn't much I can help you with. I don't use stock email clients, or exchange mail sync for that matter.

About UV, its up to you. The said values and governor - scheduler combos are purely there as a starting point for you guys. I thought I have made that abundantly clear already a few times before.

If you want to get more, its your responsibility and desire to carry out any further changes and test them according to your usage.

Thats the best I can do without actually having your device, and using it how you use it.
[Galaxy S II General] CamoGeko:
Would be great to have some feedback from Siyah 4 users out there... anybody??
[Galaxy S II General] tigerphil:
Flashed the latest siyah this morning after a ROM update so hopefully will have something in the next few days once everything has settled :)
[Galaxy S II General] CamoGeko:
Thanks mate, looking forward to your feedback... let me know if you made any extra modifications to the original MagicConfig settings and I shall add this to post 850.
[Galaxy S II General] tigerphil:
So far i've only set it as battery optimized and the CPU at -50 same as before but also disabled FD. I was thinking of trying -75 but after previous freezes etc i thought i'd stay safe for now

MagicConfig for Siyah 4.0

Hi geko95gek: What values ​​do you recommend for roms 4.0.4 with siyah 4.0?

Thanks
[Galaxy S II General] CamoGeko:
Ah ok mate, that sounds alright.

If you do end up trying some new settings, remember not to set as boot until you know they are working for you.

I'm still waiting on some feedback from few people, but the settings in post 850 should work fine. :)
[Galaxy S II General] OrangePL:
I'd also be interested to know which CPU Scheduler is best for Ondemand, since bfq seems to be gone from Siyah (it's not there on the list in ExTweaks).

Ondemand gives me significantly more battery life than pegasusq (especially in the 4.0 kernel where pegasusq activates both cores when screen's on).
[Galaxy S II General] c0x91:
True, same for me.
[Galaxy S II General] CamoGeko:
Thanks for the feedback guys! :D

I shall keep that in mind when I update/adjust MagicConfig for Siyah 4. :)
[Galaxy S II General] tigerphil:
Apparantly using my original settings since changing to latest siyah, caused freezes while my bro was playing temple run. I had to restart my phone a few times, i'm guessing thats a GPU problem so got to have a play about with those settings soon but may also try the ondemand, just giving another day for the rom and new kernel to settle then will watch my battery stats
[Galaxy S II General] CamoGeko:
Hmm... yeah mate, whenever in doubt leave the GPU settings as stock.

Ondemand should be more efficient for battery as well.
[Galaxy S II General] tigerphil:
I haven't personally touched the gpu settings only the cpu i'm guessing that by putting extweaks to battery optimized caused the gpu change so going to reset back to default later then try the same cpu settings but with ondemand, trying to get max efficiency out of the battery :D
[Galaxy S II General] CamoGeko:
Ok mate, yeah go back to default everything and just change the settings step by step.

That way its easier to find out what works and what doesn't. :)
[Galaxy S II General] alex__sp:
I'm running latest siyah 4.0.1 on RR 2.6.1 ICS 4.0.4 and after testing the -100mv undervolting It crashed immediately.

I'm testing the -75 mv UV.I hope this one runs just fine.

---------- Post added at 04:01 PM ---------- Previous post was at 03:42 PM ----------

UPDATE: I just tried -75 and it also crashes.

Now I'm testing -50 but with on demand governor because I don't like that pegasusq doesn't turn off second core quicly.

I will test trying to undervolt -75 only 1000mhz which was working for me before perfectly.
[Galaxy S II General] CamoGeko:
Sounds like your phone is choking on something...

Did you UV the GPU as well?

What is better? Ondemand/sio or ondemand/noop ?

[Galaxy S II General] CamoGeko:
Test both out for a day each and see what kind of results you get.

In my experience, sio gives smoother performance overall. Noop is simpler, and gives slightly more battery life.

Yeah I did.

I'm not sure but right now I'm running it undervolted -50mv and it's working great!.I even UV -75 the 1000mhz frequency.

[Galaxy S II General] luisfer21069:
i being using your configuration for some time now and pretty good results, but am wondering if you are gonna update the MagicConfig with Siyah 4.1 because i am seeing new features like more CPU states and the 4th GPU step and wonder what configs we can use now.

PS: never mind the new step features have being disable for now
[Galaxy S II General] CamoGeko:
Once I get the testing results in then there will be a slightly modified MagicConfig, which includes the new settings. :)
[Galaxy S II General] droidstarxx:
Ok i'm trying this magic config + single core only on siyah + checkrom. Can battery last longer? I'll see.... :) anyone tried this setup?
[Galaxy S II General] CamoGeko:
That's pretty much the perfect combo, you should get between 4-6 hours screen-on time easy! ;)
[Galaxy S II General] droidstarxx:
Thanks sir but now im trying 100mhz - 800mhz noop + con single core. I think this one is also stable.

4-6 hrs on screen time plus more standby time right? Hahaha thanks
[Galaxy S II General] CamoGeko:
Yes of course, it will total around 15-16 hours and within that time about 4-6 hours screen-on. This is with a stock battery of course.

Btw, I wouldn't choose to put it only on Single core myself... I'd leave it at hotplugging but it's up to you if you wanna try something different. :)
[Galaxy S II General] droidstarxx:
Yes sir thanks :) which one works for you better? Neak or siyah on GB ? Thanks again

running single core gs2 siyah kernel + crrhd v6 + modified magic config
[Galaxy S II General] CamoGeko:
Siyah is best... and always has been. ;)

I have had issues with a few NEAK releases so I gave up configuring it.

Settled ROM and siyah 4.0.1. Screenshots of settings can be supplied if needed (quite a few pics though)
[Galaxy S II General] Tricks25:
i started using this config around 2 months ago with my personal touch to make it more stable and i must say it really is a big help..

its the first thing i actually do after flashing a rom and a kernel (siyah usually)..

now my battery would last until night like i want to and 5+ hours screen time is easy to attain.. :D

so, a BIG thanks! :)
[Galaxy S II General] Scarface2283:
What do you mean for UV? I'm using the settings that I saw on the Page, anyway if is what I think is 800mhz 800mhz 950mhz

I mean that there are 3 levels of UV in post 850. Aggressive, less aggressive and relaxed.

Which ones are you using?

Its part of the neutrino rom, as far as i can work out its taken from the xperia S. The rom is built from a few sources so i could be wrong
[Galaxy S II General] Scarface2283:
Ah ok thanks, I liked the way it looks.
[Galaxy S II General] tigerphil:
It is a nice stable rom, a JB version has just been released aswell, theres a link in my signature if you want to check it, found this thread works perfect with it aswell :)
[Galaxy S II General] CamoGeko:
I suggest you do what tigerphil had to do and test CPU UV first, then once you find a stable value you can start on GPU.

Sent from my HTC One X
[Galaxy S II General] tigerphil:
All seems to be running smooth aswell now, thanks to your help. Yesterdays reading was with ondemand but i'm sure i was getting higher with pegasusq so i've switched back and going to see how it goes :thumbup:
[Galaxy S II General] Scarface2283:
I'm starting with CPU, I don't get much of all the settings (ondemand,etc) I'm reading a thread to see if I understand, and choose what is best for my use.
[Galaxy S II General] tigerphil:
i found pegasusq and ondemand are both good for battery life, everyone will get different readings though, happily cpu uv -50 but have seen people at -75 and stil running smooth. After i was advised i got a stable uv'd cpu, run it for about a week before touching the gpu, avoided alot of frustration with reboots, S.O.D etc. All the advice given and read in this thread is perfect for someone being 1st time user of UV :)
[Galaxy S II General] Scarface2283:
Yes is perfect here very clear,i'm starting from -25 going up to see the different type of way, what is S.O.D.

I thought to use conservative, as for cpu i allways thought at 1.6 ghz but I see that at 1.0 ghz is fine aswell.
[Galaxy S II General] tigerphil:
Personally i'd go backwards, once the freezes etc stop you know your on the right tracks, the higher the uv, the better your battery life could be :)

As for S.O.D (sleep of death) i only came across it twice, the phone doesnt respond at all. Had to reboot into recovery to clear all the extweaks settings and start from the beginning again.
[Galaxy S II General] Scarface2283:
Yes you are wright, I had that problem before but I thought it was the problem of juice defender, until now nothing of that, I notice that even the heat is lower than before.
[Galaxy S II General] CamoGeko:
Or you can just not set the settings as boot.

Then once your device freezes, just turn it off and back on again, all tweaks will be back to default.

There wont be a need to go to recovery and clear settings. :)
[Galaxy S II General] Scarface2283:
I'm using ExTweaks Plus, what are you using?
[Galaxy S II General] CamoGeko:
I was using the same.

You will find that most people with Siyah use that app. ;)
[Galaxy S II General] Many40:
Hi,

Sorry for disturbing your conversation but I think that using ExTweaks it will be not possible due to the fact that this app doesn't change values in real-time but when you change something it will be applied only after reboot. So to check UV I would recommend an app like VoltageControl for example (without setting changes as boot).

Regards
[Galaxy S II General] CamoGeko:
Hmm... to be quite frank... I've never noticed that in the ICS versions of Siyah + ExTweaks.

The values have always changed for me, however... I didin't double check this with any other apps. So who knows, maybe the UV doesn't stick until its applied.

Maybe you can do some testing of this and provide screenshots??
[Galaxy S II General] Scarface2283:
I'm looking now at Voltage control, ExTweaks as more settings, voltage control as the cpu setting and the voltage of battery at certain speed of the cpu.
[Galaxy S II General] Many40:
Just rechecked this to be sure and can confirm what I said:

1. When changed max scalling frq in ExTweaks from 1 000 000 kHz to 1 200 000 kHz it was immediately visible in VoltageControl app,

2. When changed CPU undervolting in ExTweaks from -50 mV to -25 mV - in Voltage Control it changed nothing - for example on 1 000 000 kHz it was still 1150 mV set what corresponds to -50 mV. When rebooted a phone, then in Voltage Control all voltages increased by 25 mV so accordingly for 1 000 000 kHz it was 1175 mV.

Summarising - ExTweaks changes frequencies in real-time but voltages not. I thing that this concerns also many other settings but haven't checked it yet.

Regards
[Galaxy S II General] tigerphil:
I've never noticed anything in extweaks where i can change weather or not changes are set at boot, i only get the option of save or discard changes, unless its an option in the paid version. I did notice voltage control had that option on my mates phone but i haven't personally used that app
[Galaxy S II General] Scarface2283:
On voltage control the cpu is like ETweaks, but not the voltage, but one question if I change the voltage of the Mhz for the Ghz that I'm using will it be a problem with ETweaks?
[Galaxy S II General] CamoGeko:
I'd advise to use either one or the other, not both.

Sent from my HTC One X
[Galaxy S II General] Scarface2283:
Yes is what I thought, but what would be better to use, voltage that looks simple or etwaeks that has more information.
[Galaxy S II General] Scarface2283:
I'm going to start to use SetCPU, I saw the Video and it seems good.

I have only problems with the undervolting of the battery with the speed of the CPU.
[Galaxy S II General] CamoGeko:
Can I just ask, why don't you wanna use ExTweaks again?

Sent from my HTC One X
[Galaxy S II General] Scarface2283:
I'm looking to all of the apps and see what could be better, Until now I must say that:

Voltage control is very simple and easy to use

ExTweaks is the more complete, with the possibilty of many tweaks

SetCPU until now I see the good thing of create profiles were to select the speed of the CPU

Very very nice thread. Knowledge is best when shared. Thanks for sharing.

Will try this and report on my experience.

[Galaxy S II General] Igor 3:
What kind of governor is conservative, the scrolling is so much smoother than with pegasusq where I always get microlags. But i noticed that battery is draining a little bit faster. Im on sio+conservative. Also what about scripts, is there a big diference betwen them. Im on Linux kernel default. I dont otice much diference betwen the 3 of them when im on conservative governor but when i put pegasusq and change to thunderbolt script the scroling becomes mush more worse.
[Galaxy S II General] tigerphil:
Extweaks is easy to use even though it does have alot of options but see that as fine tuning :) personally i tried setcpu after a mate recommended it but i didn't get along with it, the profiles are a good idea but your probably notice that once they're set up, they all look pretty similar, i gave up with it within a few days

---------- Post added at 10:28 AM ---------- Previous post was at 10:22 AM ----------

I found this a while back about the governor's, hope it helps

http://xdaforums.com/showthread.php?t=1369817
[Galaxy S II General] CamoGeko:
ExTweaks is the easiest and most complete app to use. Hence why the screenshots were done of the config set up there. Why are you guys questioning it, just do as you are directed. You don't need to worry about what app you use and what app you don't use.

Second thing... all links to useful threads are in 1st post. Including a link to droidphile's thread about kernel stuff, schedulers/governors...etc..
[Galaxy S II General] Many40:
Totally agree. I use SetCPU only to monitor governor's tunables. I think the main app for us to manage kernel's tunables should be ExTweaks as it was born with Siyah and it can tweak most of them. What I miss in ExTweaks is finetunning of UV. I use for that VoltageControl (and only for this) to set some bigger UV on some particular frequencies. Regards
[Galaxy S II General] Scarface2283:
I think that all the 3 apps are good, each of them has something that other doesn't have.

For SetCPU the possibility to select the profiles is good even if for my use is needed obly if I go over 45° Degrees or with screen off.

ETweaks is true the more complete but at the end what is needed, possibilty to select CPU, undervolting of the battery, personally I don't use BLN but NoLed.

Voltage Controle well is ok but very basic.

For what I'm getting now SetCpu is a good way to go, but I like to test them all and see the real different.

Until now since 10 o'clock I'm still at 93% of battery, I'm using juice defender aswell to see better life of battery, I will upload photos of what I'm running and the battery use.
[Galaxy S II General] Scarface2283:
So after 12 hours what can I say, I still have more than 50% of battery, So I must say that is good, Ok today was very low with use of the Mobile not many SMS, a few Whatsapp messages, and some skype messages, aswell like some Internet use, no phone calls.

I must say that in the afternoon I had a automatic reboot, and lost some battery.

First I will start with say what I'm running

ROM: UHLPS NeatRom Lite v3.0.1 Themed

Kernel: 3.0.37-Siyah-v3.4.1+gm@ubuntu #37

Radio: I9100UHLPG

Android Version: 4.0.3

Basic settings either on Apex and Mobile and Jkay

Juice Defender is set with 15 minutes program, I've configured the apps to be running only every 15 minutes, there are no apps running on screen off.

SetCPU in default I've set Max 1000mhz Min 200Mhz Pegasusq Governor Scheduler Sio.

I had some profiles that are the following:

Battery>=45°C CPU Max 400Mhz Min 200Mhz Pegasusq Governor

Screen Off CPU Max 400Mhz Min 200Mhz Pegasusq Governor

App Internet CPU Max 1500Mhz Min 1300Mhz Pegasusq Governor

Battery<=25 CPU Max 500Mhz Min 200Mhz Pegasusq Governor

I did not use any Undervoltages as I'm still not very good at it.

I'm uploanding some photos of the Homescreens so you see what I'm running (I took It when uder charge during the night), one of the Drawer, CPU Settings, and how much battery left.

Hope to get some replies, this is a very basic and nothing special settings, I think it can go better.
[Galaxy S II General] Many40:
Good work, you put so much effort to your post but to be honest as long as you don't use UV your current config is far away from MagicConfig. Regards
[Galaxy S II General] Scarface2283:
That is sure, the problem is that I don't understand the UV, in the sense of you see the photo, there is the CPU speed for example 1200MHz and under you see 1225 mV current and 1225mV saved, if I tap on I can select what UV use, but I don't understand if I need to do it for all the CPU speed so from 25MHz to 1600MHz or only from the one that I use so from 400MHz to 1500MHz
[Galaxy S II General] Many40:
General rule is more UV more battery juice saved but less phone stability. You should find golden balance for your phone (this maybe different depending on a hardware used in someone's phone). So my recommendation is to start UV from -25mV set in ExTweaks (remember to reboot) then observe phone's stability for some time. If it works you can continue with bigger UV. If the phone freezes, reboots etc go back to previous UV (you will have to reset ExTweaks in CWM) and afterwords you can try finetunning UV step by step, frq by frq using SetCPU or Voltage Control (don't set on boot before testing), of course for frequncies you gonna use (your scalling range 200 - 1000 MHz) + extra profile you set 1300 -1500 MHz.
[Galaxy S II General] Scarface2283:
So the use of ETweaks is ok even if I use setcpu or voltage control or even both or do I need only to use one, because in a post before it was wrote to use only one
[Galaxy S II General] Many40:
I think that it should be avoided to use two or more apps doing the same especially in real time. I use Voltage Control for UV only because I miss a feature to change a voltage for single frq separately in Extweaks. But for example I never set scalling frq range in Voltage Control because I do that in ExTweak (to avoid any conflicts).
[Galaxy S II General] Scarface2283:
So I could use ETweaks only for the UV and SetCPU for the settings of the CPU, but not use them both to Overclock or Underclock the CPU, but I will need to untick the boxes of the CPU settings on ETweaks.

But anyway I can do all of that with SetCPU, CPU settings, Profiles settings, and UV.
[Galaxy S II General] Many40:
I am afraid that it's not possible to ucheck "boxes" for CPU settings ("CPU scalling settings"). You have to set something there. In this case I recommend that you use ExTweaks for general CPU scalling settings plus UV and SetCPU for special CPU profiles (if you really need them). Then in SetCPU you would uncheck "set on boot" option (under MAIN tab) for general CPU settings (they are set already in ExTweaks). You would then check "Enable profiles" for your CPU profiles and additionally/optionally (up to you) check "Set on boot" under VOLTAGES tab for finetunning of voltages. Regards

What battery drain is typical for on screen activity?

Messaging

Web browsing

I tried less aggressive and deep sleep is fantastic. But once the screen is on constant I see say 1% drop every 2 mind or so.

Hi,

just started to use the less aggressive settings through extweaks.

I set them exactly as described at the op.

we'll see how it goes...

I have one question though-

In the settings it says:

Default cpu scheduler = sio

I didn't see this option in the cpu tab.

I saw there is a default i/o scheduler under misc tab.

By default it's set to cfq.

Is that the same thing? should I change it to sio?

Thanks!

Well, it seems that my device can't handle the - 75 undervolting... I had a few freezes.

I changed it to -50.

For now it seems okay.

Strange issue, after one of my freezes/reboots, my swiftkey keyboard lost all the dictionary and personalization... :eek:

Thank god for titanium backup... I restored all of its data.

And a question about extweaks-

After every reboot it automatically restores and sets the settings that I defined, right?

I noticed that sometimes after a reboot that happened after a freeze, extweaks returns to the device's default settings.

Is it kind of a safety mechanism?

Thanks!
[Galaxy S II General] CamoGeko:
That's weird with the SwiftKey. Never had that happen to me before.

Also, the settings restored to default probably because you forgot to set them as boot.
