Can confirm.

For my phone and my usage, Siyah 2.6.7 had better battery savings than Siyah 2.6.12.

As 2.6.7 was on XILA2 ROM, I removed its results from my last result list.

Here are my latest test results in non-dev Thread => http://xdaforums.com/showpost.php?p=22413999&postcount=847.
[Galaxy S II Original Android Development] hausmanis:
Can also confirm the above, actually 2.6.12 is the worst batterylife that Siyah have had since 2.0 for me... :( it has gone from the best batterylife kernel into one of the worst with the latest release, not meaning to taunt anyone just giving critism feedback

Hi Gokhan,

There is a new develoment concerning USB DAC support for our device in GB. Would you look at this topic and support it in the upcoming kernels if possible?

Same goes for me. 2.6.11 had waaaaaay better battery life than 2.6.12. Huge difference here.

I'm seeing an issue with the phone not staying off when charging. I plug in the charger and I see the battery icon.... then it boots into recovery. I'd like to see that fixed if possible.
[Galaxy S II Original Android Development] MistahBungle:
Can't speak for the AT&T version, but I had the same problem with 2.6.11 on I9100. Reflashed my rom (without wipe)/reflashed Siyah which fixed the problem.
[Galaxy S II Original Android Development] teiglin:
So, I came across the video playback issue last night. I'm not surprised it hasn't been more widely reported; it had happened to me several times before I was certain there was a problem with the phone rather than with the videos I was playing. Basically, the video would choke and my player (I use MX) would restart with software rendering on. It seemed to take anywhere from one to five minutes of hardware playback before this would happen, and since things chugged right along with software rendering, I didn't really worry about it--since there are encoding features that are not supported by our hardware, I made the assumption that it was the videos' fault.

Anyway, I went ahead and disabled AFTR rather than mess with 2ndcore app, which I've never used before, and as expected, it fixed the issue. Looking forward to an update with Entropy's latest patch. Thanks!

I also posted in the other thread that i reverted from .12 to .11 because of sod's. apparently the sods are caused by the reminder function of go sms pro which notificates you again after some time. happened once with .11 now and i switched it of. will have a look at it.

Done.

Why I get this message and how can I do this?

Well, you need to mount the /sdcard in the mounts menu first, then you can format it ^^

after the fourth (!!) "SOD" (the screen is black and unresponsive but it reacts to the volume buttons and the power button ... weird) in the last 2 days and overall very bad battery life with wifi on I'm back to 2.6.9 again.

no idea what's wrong with .11 and .12 but they have issues (battery, stability, responsivness), at least on my phone.
[Galaxy S II Original Android Development] c0x91:
no... and i've not a external sd card
[Galaxy S II Original Android Development] CamoGeko:
That's why you get that "Error: mounting SD card".

Mount "emmc" instead. Or better yet, do a hard reset after booting into Android. :)
[Galaxy S II Original Android Development] rauschkugl:
this doesn't happen to me and i also use heavy undervolting. never had a sod on .12 and can't imagine how so much people could get it. if you installed scripts remove them all, if you undervolted remove it, clear dalvik after installing new kernel. i never had a problem on any version of siyah despite my heavy undervolting!
[Galaxy S II Original Android Development] PedroMRP:
I hate I don't have any of those problems with .12 :P
[Galaxy S II Original Android Development] Misterjokerboy:
Same here, Mine is undervolted quite a bit and I haven't had a single SOD either. Only upgraded to to .12 2 days ago though
[Galaxy S II Original Android Development] veyka:
I backed off 50mV on my 200mhz UV and its working fine now, so maybe 2.6.12 is just more sensitive.

Also I haven't had any battery drains or other issues so far.
[Galaxy S II Original Android Development] Entropy512:
That's most likely due to the interactive governor. It causes a hung task timer to fire when the phone is in LPM charging. That's why I removed interactive only 1-2 releases after putting it in.
[Galaxy S II Original Android Development] tolis626:
I too wonder how people manage to get these issues.Every stable release of Siyah after 2.0(I think I haven't used any previous versions) has been working working like a charm for me.Stable and with more than excellent battery life,even though I undervolt to my CPU's limit and overclock at 1.5-1.6GHz,not to mention I have my screen's brightness high(70-80%).How people have issues is beyond my comprehension.Maybe rooting and modding isn't for everyone... ;)
[Galaxy S II Original Android Development] teiglin:
Well, for one, you have unusually good silicon to be able to run such aggressive voltages and be stable, so not everybody is that lucky. More importantly though, many people just don't take the time to understand how to undervolt safely and always assume that there is a kernel problem when they copy someone else's settings and scripts blindly. I also suspect that the majority of people run stock or at least conservative settings without issue and don't bother to come complain in the thread. :)

I will note for what it's worth (admittedly not much, since I forgot to pull the last_kmsg) that I had an SoD while messing with the video playback issues. I'm guessing it was related to said video issues, since I'm running the same voltages I've had for months, and been on 2.6.12 for almost a week with no other problems.
[Galaxy S II Original Android Development] stylez:
We also have to take into account some ROM combo's cause issues, along with not clearing cache oh and then the not letting bed.

But since so many ROMs some will cause problems no matter what's intergrated by users.

I had SOD but with a little voltage up on low end all seems fine, don't ask about battery since no combo/ROM/Modem/Kernel provides enough but that's just part of having a blazing phone and not being able to put it down :-D

[Galaxy S II Original Android Development] stevehkim:
i also noticed some roms have preinstalled init.d scripts so people may think they dont have anything in there but they do. plus im sure every flash and download arent perfect. bad flashes/downloads are a dime a dozen and every phone isnt created equal. i have to admit though i have been lucky as i havent had hardly any issues with siyah and can undervolt the **** out my phone. as i stated before 2.6.1 and 2.6.7 are rock solid for my daily usage with perfect combination of battery and performance.

Hi guys,

First of all, thanks to Pikachu, chadouming, and qureyoon for the stress test tips and links. I have tried the experiment (playing videos using MX Player) suggested and this is what happened to my phone:

After I set to 100Mhz(min)/100Mhz(max) and UV to 850, I played the 7 recommended videos using MX Player. I was expecting freeze or hang to occur pretty soon but none. Strangely, the videos never hang or freeze but rather it was playing very laggy. Laggy but never hang. I played the 7 vids back to back for about 4 loops w/o hang. So I moved on 200/200 with 850v too. Same thing happened. Then I moved to 500/500 with 850v. Same thing again. By this time, I thou to myself that sth seems not right. I thou the phone supposed to hang or sth. :confused:

So I changed my experiment. I decided to set 100/100 with 850v and let it slp by screen off. SoD happened. Kinda expected. So I rebooted and increase to 875v. Strangely, SoD again. Same for 900v. So I tried with 200/200 next. Same result, even for 900v. Same goes for 500/500 with 900v. In the end, I revert back to my old setting which is 200-1000Mhz with volt ranging from 850v to 1100v. (850 875 950 1000 1100). Strange thing is that now there is no SoD even with the lowest volt set at 850 for 100Mhz.

Anyone can enlighten me? Another qns is that after this setting has been set, when I tried to adjust the volt down by 25v for, say, 1000Mhz from 1100 to 1075, my phone hangs as soon as I hit the 'apply change' button. Same for 800Mhz when I adjusted from 1050 to 1025. Can I say that these volts are the min. requirement for my phone?

I am using noop/conservative. Does this play a part in the stress test? I thou by limiting the min. and max. at the same freq, the scheduler and governor should not have any role? :confused:

Appreciate if gurus out here can help me! Thanks!

Can I use this kernel for my phone

Hello,

first, thank you for your job.

My question : Can I use this Kernel for my phone ?

Number model : GT-I9100

Android Version : 2.3.5

Base Radio: I9100BUKI1

Kernel : 2.6.35.7-I9100XWKJ3-CL647431 root@DELL82 #2

Number version : Gingerbread.BUKJ3

I just root my phone with the Kernel Chainfire to have the CMW.

And my phone has the ROM Samsung SFR with Touchwiz.

If I can use your kernel with my phone, wicht one I must donwload ?

the basic, the att or the kor ???

(For information : I read the post #2 with the Q&A but I have not all understand).

Thanks.

What is your Bus frequency in sleep mode ? I was having SOD when being at 133Mhz, got to use 266.

# Max Cpu Speed in sleep mode

echo "6" > /sys/devices/system/cpu/cpu0/cpufreq/deepsleep_cpulevel

# Bus Frequency: 0: 400 mhz | 1: 266 mhz | 2: 133 mhz

echo "1" > /sys/devices/system/cpu/cpu0/cpufreq/deepsleep_buslevel
[Galaxy S II Original Android Development] pikachu01:
It sod because sleep requires it to be at 800 mhz when it sleeps. It won't consume energy though.it just needs to sleep at 800mhz.. And when it hangs at apply, yes that's the minimum.

Governor doesn't play a role when you limit the frequency to the one you're testing.
[Galaxy S II Original Android Development] Honusnap:
For what i see... mine is sleeping at 200Mhz (Testing Phenomenal, so limited to 200Mhz, was 100Mhz with Siyah)...

And if you go from 1000 to 1025 .. apply than go from 1025 to 1000 ... apply .. does it hang ? If not than certainly 1075 is too low for your SGSII
[Galaxy S II Original Android Development] sergedevelopers:

[Galaxy S II Original Android Development] eric-filth:
with neak kernel the sleep freq is 500mhz
[Galaxy S II Original Android Development] PedroMRP:
The deep sleep freq can be adjust, mine for example is at 500MHz but it's device dependent, some devices can handle a 500MHz deep sleep other can't.

It's a case of trial by error just like undervolting some devices can handle lower voltages other can't so if you have SOD with lower deep sleep freq increase it to 800MHz and it should be fine the same with undervolting if you have problems with a certain voltage increase it until you haven't any problems.

Before reporting any problems with battery life please check if you have any app that have a odd behavior using BetterBatteryStats, don't use task killers and keep in mind that wifi on or data packet with 3g on or having 3g on all time eats up the battery if you aren't accessing the internet turn off those things including sync.
[Galaxy S II Original Android Development] eric-filth:
Thanks for this.

So im had luck with my device for can use undervolt and min freq sleep?

Obrigado pela explicação.

Então eu tive sorte por conseguir usar deep sleep com 500mhz e por usar undervolt sem ter problemas?
[Galaxy S II Original Android Development] Honusnap:
Well i suppose that in deep sleep, frequency is egal to zero... it should be, only radio and perhaps some others chips are waken.

In my case, i use deepsleep_cpulevel = 6 => 200Mhz, but i suppose that this "sleep" frequency is only the frequency at which the cpu is setted before entering "deep sleep" and perhaps the one when it woke up after an interuption is triggered... (just a supposition)

Hi gokhan and others , a quick question

1. we all are waiting for the source code(ics) from samsung right? will the new source code and kernel v3 will be compatible with gingerbread?

2. If the code is not compatible with gingerbread, then what will be the current state of kernel development? will we get two separate kernels like 2.x for GB and 3.x for ICS?

3. Are the list of new features that will be added for ics is ready?

4. Will the existing features of siyah 2.x will be added to 3.x?

Unlikely since there isn't any Android 4.0 kernel source. Ask Samsung for it. :)

Nope, if you have accelerated battery drain it's not due to undervolting.

Before it gets to deep sleep, it'll scale to 800MHz and then sleep (CPUSpy will show it as deep sleep though).

You can check by using Root Explorer/File Expert/Root Browser by navigating to these files:
