    Hey guys,
    I have heard quite a deal about this siyah kernel.since I am new to rooting and flashing, I haven't quite got the swing of it yet.
    I am using resurrection remix 2.2 now and this is my first ICS ROM experiment. Is the latest siyah kernel better than the kernel used by this ROM by default? Since I haven't changed it yet.

    Siyah is one of the popular ones certainly, and is performing very well for a lot of people.

    However, there basically is no such thing as a "better" kernel, as what is better for one, may not be the case for another.

    Try it for yourself and make your own opinions.

    A few weeks ago gokhanmoral, the developer of the Siyah kernel, stated that he now had acquired an SGSIII and that his new wife had his SGSII. Therefore he would be doing less, "risky", test releases as he did not want to upset his wife's phone... or his wife, come to that!

    Well, I've been on the latest Siyah release, 3.3.2, for about a week now and all I can say is... GREAT!

    This kernel has performed flawlessly for me and has contributed to some excellent battery life when used in conjunction with NEATROM Lite. In fact, my battery life has never been this good, even on Gingerbread. My Android OS, on the screenie below, shows only 4%!

    So, a big thank you to gokhanmoral and as far as I'm concerned, your marital life is safe! :D

    Quite fancy trying this out, I'm running my Vodafone Stock ICS, is it worth just changing the kernel in terms of battery life or is it better to put a new ROM on? I've never done anything with my phone beyond basic rooting with CF-Root.

    What's the easiest way to go about it, is it just through CWM? Or Odin?

    Both NEAT ROM Lite and Siyah were installed using CWM Recovery.

    Do you get any strange behaviour at all with yours?? Quite a few times mine gets to about 30% then will suddenly dive bomb after doing minor tasks.

    Other than that mine would be equal I reckon, I'm on 3.3.2 also but just stock ROM.

    Out of interest what does your Android OS show as in your stats? Mine's the only other thing thats consistently high - today its at 28%. Any idea if this is workable?

    I did right after installing it but used the Reset Fuel-Guage Chip function in ExTweaks Plus and after 24 hours I no longer had a problem.

    The NEAT ROM Lite is a big battery saver as far as I am concerned.

    My Android OS is shown in the screenshot as 4%.

    I just hit the Reset Fuel-Gauge chip there and my battery went from 44% to 16%!!! I'll see how it fares after I charge it.

    I have Android OS & Android System :

    Think I may give Neat Lite a go...

    Oh yes, you're right, It seems that NEAT ROM Lite doesn't display it the same as stock. It doesn't appear at all in fact.

    Right on cue!!
    A quick couple of backup's and a reboot.........

    Notice the big dive at end - from 62% in last post to 19%!!

    Its the nature of the fuel gauge beast. It requires no calibration whatsoever, but its drawback is it can go out of kilter when its power supply goes awol. On such drops it will actually creep back up slowly if left unused until it reaches its true value once more.

    cozins17 Well-Known Member

    Yep - well almost.

    Having been out for hour without phone, ive come back & its creeped back up to 29%! Strange cause if I carry on using phone it'll go down & eventually off!

    I'd like to download a STABLE version of the Kernel for SGS2 ICS. It doesn't say which releases are stable on the site. :confused:
  17. Hawker

    Hawker Well-Known Member

    All versions of Siyah are stable. Why would you think otherwise?

    3.3.2 is the pick of the bunch

    I flashed this just a few days ago with NEAT, and ExTweaks.

    Wow, I am very impressed. I had 1 day and 10 hours, and about 40% left before I murdered the battery with a game. Doing simple things like email and social networking doesn't seem to drain this so much now.

    Very happy :)

    I rooted my S2 a few months ago and all was good. I did the 4.0.3 update and wanted to root again. I managed to brick my phone and I managed to fix it without a jig or other things that others had tried. So I have this kernel installed now.

    I'm all for using it but the right two buttons don't work now. Is this supposed to be like this?

    Could you go to Settings > About phone > Model number... and give the information there.
