A few posts before I have write my method for use extreme version, and use tegrak overclock ultimate to set the voltages of medium.. You will have better battery than medium version because extreme version has more undervolting things.. This if your device haven't problem with other things that has extreme version. (I had to reboot twice for make my phone boot with extreme version, but after change voltages have no problem at all and better battery than medium..)
[Galaxy S II Android Development] dude0014:
Will try the app. Would be awesome if fenomeno83 or anyone else could compile an "Almost Extreme" version. With Medium CPU voltages, and Extreme other voltages.

I have no clue, and too scared i'll mess up trying to make something like that of my own
[Galaxy S II Android Development] iZz0s:
Hi !

Im testing currently some Kernels, in the past it was Fluxi and Siyah.

With Phenomenal i have a Problem...

First, im using the Ultimate Cleaning Script and then im falshing Phenomenal 5.5 Kernel through CWM. First i tried Extreme but it got a freeze, so i choosed medium version.

The Problem is that the default governor is set to "userspace" and cpu spy says that my handy is running all the time on 1000 Mhz.

I've installed now SetCPU and there i have seen that it is fixed on 1000 Mhz. I've reflashed that Kernel already!

Dont know what to do. I've changed manually now to ondemand but it would be cool if i got some informations about that issue from the developer or somebody who have maybe an answer for that ^^

Thanks

Hey guys can anyone tell me if this kernel will work with WanamLite 11.9 Rom or no..???
[Galaxy S II Android Development] pissyhun:
I flashed this kernel many times. Default governor is ondemand. In speedmod too.
[Galaxy S II Android Development] pissyhun:
So lazy u are. Yes will work. Read first page carefully.
[Galaxy S II Android Development] Ausboy 2011:
loving 5.5 medium, still had the problem with freezing on extreme but i never did on gb, anyhow ill stick with medium! 50 % battery left with 3 hours screen on wifi on no sync, so ill post a pic if i make it to 6 hrs screen on ;) awesome kernel dev keep up the good work
[Galaxy S II Android Development] LIPA:

And perhaps Normal is not very usefull ?
[Galaxy S II Android Development] It_ler:
Now on second battery cycle, Phenomenal 5.5 Extreme works fine on my XWLPD ROM.

Very stable, very smooth and very good battery life on my phone.

Nearly the same battery life as Phenomenal 5.4 Extreme, and only a little bit worse than Phenomenal 5.3 Extreme (but smoother).

So IMO, I very good balanced kernel.

Have a look at my latest kernel test results here => http://xdaforums.com/showthread.php?p=26775950

And feel free to comment or post your own experiences with the different kernels.
[Galaxy S II Android Development] defenderko:
I really don't know how you people are getting that long battery life... Mine is on 55% bat , and I have 1h40 min... Phenomenal 5.5 medium and lp7 stock.. Wifi on when needed,3g also.. I don't have twitter, Facebook, or any of that sh.... Plus most of those Samsung preinstaled apps are disabled or deleted.. Battery checked and it is ok..

[Galaxy S II Android Development] jamespangck:
You must recycle you battery at least twice. What this means is that you use the phone until battery flat and it shut off by itself. Then 3 minutes later, plug in your charger and charge till full without using, if possible. Usually I let it charge overnight.

Try this and let me know if it helps.
[Galaxy S II Android Development] defenderko:
Yap, I am doing that once or twice a week!

I'll make dump file in bbs and will post it .. Should I wait till battery is almost empty? Now it has 48% ..
[Galaxy S II Android Development] Ausboy 2011:
Use newer base i find lpd the best even tried lpf/lpw. Turkbey Rom is a great Rom
[Galaxy S II Android Development] muoino:
Just switch from Siyah to this kernel. Used the phone for some hours and it seems that my S2 can stand with extreme version, great. But I tried many benchmark tools and this kernel seems not to have good performance for GPU.
[Galaxy S II Android Development] Karpfenhai:
Mate... this kernel is made for nothing but battery life! If you want performance, you are using the wrong kernel! Stick with siyah or use normal edition, them you have the similar performance as the parent speedmod kernel!

Guys guys guys...

I have problem with calls record on this kernel (i have FC app CallRecorder 1.2.4 that i used to record calls).

On CF-Root everything works ok. I use stock LPW Rom. Anyone have the same issue ?.
[Galaxy S II Android Development] robbo89:
Managed to break the 6 hours 30 minutes screen time with my last cycle with the battery lasting 40 hours total so thanks for the help! Not quite 7-8 hours but still more than happy with that. Deep sleep was around 87% so I'll possibly be able to improve upon that.

As others have mentioned, I'd also be interested in a version somewhere in between extreme and medium.
[Galaxy S II Android Development] Lach0:
Hello, I'm using wanam lite 11.9 with phenomenal extreme 5.5, ondemand/cfq.

I got 4:45h screen time and 1:10h call time, 24h total. 1650mAh batt.

Very smooth and fast, no FC reboots or anything, no lag in angry birds space hehe.

Problem is the screen is so bright most of the time, with siyah's and extweaks I could tweaks brightness curve, but I don't know if it's possible with phenomenal!

:)
[Galaxy S II Android Development] sefrcoko:
In the past I used Phenomenal Extreme on GB and had best battery life of all kernels. Then tried it on ICS but kept getting random FCs or SODs with extreme version. But with Phenomenal 5.5 Extreme I have no issues at all and once again achieved the best battery life of all other kernels i've tried. Thanks, this is stable and awesome.
[Galaxy S II Android Development] hardkod:
How to root this kernel?
[Galaxy S II Android Development] It_ler:
???

Phenomenal kernel is auto-rooted.

Just flash and your phone will be rooted.
[Galaxy S II Android Development] Karpfenhai:
Rofl, seriously?

Custom kernels are rooted by default, no need for that..

IT_ler was faster. do you miss something? SuperSU or..?
[Galaxy S II Android Development] hardkod:
Got superuser, but all progs told me: you have root your device first...
[Galaxy S II Android Development] Karpfenhai:
That's really weird, wipe cache and dalvik and reflash.

What does your cpu spy say?

Ah wait, you said superuser, did you deinstall supersu first?

Tapatalked from my Samsung GT9100
[Galaxy S II Android Development] hardkod:
Havent SuperSu, and CPUSpy kernel ifo exactly the same as u. Reflash doesnt help...
[Galaxy S II Android Development] Karpfenhai:
Weird, never heard that before, can you uninstall all superuser apps and reflash the kernel, after using kernel cleaning script?

Install the kernel by using ODIN, this is just fishing in the dark, no real clue what is wrong, sorry!
[Galaxy S II Android Development] hardkod:
Fix it. Reflashed Omega first, then reflashed Phenomenal. Thx for help.
[Galaxy S II Android Development] adl:
Best Gingerbread kernel for.

Now i use it on ICS and also there it´s just AMAZING how good it works and how great battery life is. Thanx for your time developing this kernel!! :D

Glad my SGS2 can handle the "Extreme" version also on ICS. :D
[Galaxy S II Android Development] It_ler:
Do you want to share which ICS ROM and which Phenomenal kernel version you are running now?

I am just curious.
[Galaxy S II Android Development] adl:
Hey mate!

Really like your kernel comparison (told you already ;) )

I use Phenomenal 5.5 Extreme with Wanamlite 12 ROM (Stock theme) with some apps removed and some tuning via the app "Auto run manager" (paid version).
[Galaxy S II Android Development] alidogar:
how to change governor

sorry for this noob question but... i have installed Phenomenal kernel 5.5 and i am on wanamlite 12.0 Rom, kernel is installed, but from where to control it? i mean i couldn't find its icon in system settings or in app drawer. how to change governor? have i done n e thing wrong? i installed this kernel via CWM and i flashed ultimate kernel cleaning script before installing this kernel.
[Galaxy S II Android Development] Karpfenhai:
There is no control, that's the main advantage of phenomenal :cool:

To control governor use either setCPU or voltage control.

Default its cfq and ondemand which fits perfect!

[Galaxy S II Android Development] defenderko:
I have this annoying situation when my phone is fully charged and when I unplug it, battery level drops down for 1-3 %, and when battery hits 6% then it rises to 8 or 9 by itself... I am satisfied with battery life though.. Any ideas? I am using 5.3 medium..
[Galaxy S II Android Development] It_ler:
Just try the following:

1. Shut down the phone.

2. Charge it fully (100%) and let it plugged in for another 15 minutes.

3. Then unplug the phone and pull out the battery.

4. Wait for about 2 minutes.

5. Put the battery in again and boot the phone.

This procedure helps me to get reasonable battery stats for 100%.

Good luck !
[Galaxy S II Android Development] championc:
Is this the best setting for best Battery Life ? I thought maybe noop and ondemand ???
[Galaxy S II Android Development] defenderko:
Thanks ,I will try this, but now there is something new: I just restarted my phone and before restart battery was on 46 %	, after restart it dropped on 14! Really annoying this battery situation.. Any help will be appreciated!

No sir, there's always a solution.

Just Use normal version, It will be ok. ;)

[Galaxy S II Android Development] Karpfenhai:
Are you using a script/app which is forcing a governor change for screen off?

Don't use setCPU screen off profiles!

Don't ever mix governors, most likely this is the reason for your issue, please check.

Regarding stability of phenomenal:

4 charge cycle, not a single issue! :D

[Galaxy S II Android Development] sefrcoko:
Try installing the .tar version of Phenomenal via Mobile Odin instead of the .zip CWM version. My phone supported Phenomenal Extreme on Gingerbread, but always seemed to freeze with ICS (I tried normal, medium, and extreme versions and always got SOD). Once I flashed the .tar versions of Phenomenal though, everything worked like a charm. Currently using Phenomenal Extreme 5.5 with WanamLite 12.0 :)

[Galaxy S II Android Development] viscocesco:
Where is the difference between CWM flash and Mobile Odin flash?

Why this difference result ?

Omega Supporter
[Galaxy S II Android Development] sefrcoko:
Supposed to be the same, but lately i have problems with the .zip files and no problems with the .tar files. As far as I know, the mobile odin files are the originals, which are then made into .zips for convenience and flashing through CWM. CWM used to be easier for people to flash than Odin was, but now with mobile odin there's no big difference. So for best results use mobile odin and flash .tar versions.;)
[Galaxy S II Android Development] Karpfenhai:
Sounds a bit like Voodoo to me, but if it works for you, then lucky you ;)

For me there is no difference between tar and zip, extreme on ICS does never work..;P
[Galaxy S II Android Development] gabi11:
I know it's not related directly to this thread, but if you started explaining then I have a little question about flashing kernels through mobile odin-

When I flash a kernel through CWM, I wipe cache, dalvik and run the kernel cleaning script. as far as I know, those are the actions that are recommended for a clean kernel flash.

What do I need to do when I flash through mobile odin? just flash without any wipe??

looks a little weird to me...:confused:
[Galaxy S II Android Development] Fishawy:
Thank you very much for this. I'm still on GB ROMs "Turkbey in particular", and after several trials am not planning to switch to ICS anytime soon, since there are several apps that are not running properly on ICS "Such as AutoCallRecorder and CacheCleaner NG" .. Been switching between (Phenomenal / Void Echo / The good old Phoenix) for a long time. Now I have much more varieties to try.

Thanks again! :)
[Galaxy S II Android Development] superleeds27:
Probably get shot down for this but:

Can we control cpu items with a program? Voltage control? Governors etc?
[Galaxy S II Android Development] Karpfenhai:
Voltage control, setCPU, all are working.. but, dont blame the kernel for SOD and dont touch the voltages!

Good luck ;)
[Galaxy S II Android Development] championc:
Hi fenomeno83

Congrats on such a superb job. I was a fan of 4.0 on GB and now I'm on ICS so this was an automatic choice.

One question and maybe more of a question for It_ler but is anything more that can ge gained by allowing the CPU to run at a minimum less than 200mhz ? I noticed that Siyah can be set as low as 25mhz
[Galaxy S II Android Development] It_ler:
I could not recognize a significant difference for kernels using 200MHz or less as lowest frequency.

But I didn't test the same kernel with different minimum frequency.
[Galaxy S II Android Development] sefrcoko:
Not sure actually. There is an option in Mobile Odin to wipe data and cache but I don't use this option as we normally don't wipe data when flashing a kernel. There is also an option to wipe dalvik cache but it is always greyed out so I don't use it either. So I just flash the kernel and all works well for me on Phenomenal Extreme 5.5.
[Galaxy S II Android Development] milan188:
Just moved over to ICS... Neatrom LPG 5.5 extreme. I'm fairly happy with my battery usage.... Deep sleep drain is almost non existent. However when I use my phone to do some fairly simple tasks like tapatalk whatsapp and some browsing with opera mini I feel my phone drains quite quickly. The battery indicators are telling me my screen is draining the battery quite a lot compared to GB. I know this is not GB but I just want someone who has been on ICS for quite a while to confirm if my results are normal.
[Galaxy S II Android Development] It_ler:
To find wakelocks, which prevent your phone from deep sleep, it would be helpful to have Better Battery Stats (BBS) logs.

Have a look at the BBS thread, where you should post your logs for examination by the "experts" => http://xdaforums.com/showthread.php?t=1179809
[Galaxy S II Android Development] milan188:
I meant to say my deep sleep is very good :D but I got lots of drain when screen is on
[Galaxy S II Android Development] Karpfenhai:
Cmon Man, 5:20 is pretty good!

Is this with stock battery?

Between 6 and 7 minutes / % is perfect.

To gain more juice, disable auto brightness and use screenfilter

Limit your CPU, 800 mhz is way enough.

Regards.

[Galaxy S II Android Development] milan188:
Yes it's stock battery I feel like it's getting weaker I have had this phone for 10 months now... I froze lots of silly stock apps and I limited cpu to 1000... My brightness is just above the lowest. What does a screen filter do?

Reduces the brightness even more :D

5h 20 min with the stock battery is more than good.. I have the same (and not always) with 2000 mha battery..

But in Greek sun (most of the time brightness auto= max) 1200 mhz, medium phenomenal. And many many services delete also.

Did someone tried this (english users google translate):

http://goo.gl/CssEm

Pnenomeno83 could you do something like this?
[Galaxy S II Android Development] Doeyourthing:
Verry Verry strange

Nooooo, is not a Voodoo.

Today i did flash the zip file version 5.5 extreme through CWM, the phone get stuck at the bootlogo or get stuck when scanning the applications after pass the bootlogo.

Now i did try Phenomenal 5.5 extreme.tar with Odin3 and no problem at all. No freeze, playing a video and games. Again no problem.

Only thing flashing through Odin that you counter will increased.
[Galaxy S II Android Development] It_ler:
Just use Mobile Odin app from Chainfire to flash tar file without yellow triangle and increasing the flash counter.

And for ICS ROMs, you can use TriangleAway app to reset the counter after flashing.
[Galaxy S II Android Development] hassi4042:
does this kernal support multi dpi? 200 dpi.

Great Rom Dude
[Galaxy S II Android Development] bervin:
yes.. dpi is not kernel related
[Galaxy S II Android Development] hassi4042:
Stuck on galaxy s2 boot screen. After changing dpi settings :(. Changed to 200 dpi runing omega rom
[Galaxy S II Android Development] hassi4042:
Stuck at Boot Screen, when i applied 200 dpi setting in omega rom :(
[Galaxy S II Android Development] :
Read it all the time.. It is because you didn't do it well or use an application to do it that is not compatible with ics. I always do it manually with root explorer, open with text editor and erase the second line in witch writes the dpi value. This way working in all rom. Have done it more than 100 times...
[Galaxy S II Android Development] hassi4042:
Er

I changed it with root browser the line in build.prop

to ro.sf.lcd_density=200

Thats all na? But still stuck at boot screen with this kernal.

There is an other file called build.prop.bak. Should i edit that to? And

what is ro.build.user=dpi? Which line shoild i edit in which file
[Galaxy S II Android Development] :
And if you find a second line with dpi value, erase this line. Every rom I have use have 2 lines with dpi value. Not all rom work if you doesn't delete the second line.

The 2 lines are the same

ro.sf.lcd_density=240

ro.sf.lcd_density=240

The .Bak file doesn't matter.

I supose you change the build.prop of the folder /system

This is the one..
[Galaxy S II Android Development] hassi4042:
Thanks man i use to change both values. But this tme i delete the 2nd line and that did the trick :D
[Galaxy S II Android Development] hassi4042:
After the dpi problem solved i tested this kernal and i am like WOW :eek: man this kernal is so cool so so cool. I need battery timing and this kernal giving me 5 hours of screen on time. Man that is on stock battery. I still cant belive this that our sg2 can acheive this

Hi, thanks for the effords. Should I use the kernel cleaning script if I update from previous version of phenomenal?
[Galaxy S II Android Development] It_ler:
As I don't use any (init.d) scripts or other manual tweaks, I never use a kernel cleaning script.

If you changed some kernel/system settings in previous kernel versions, then it would be "safer" to run the script.
[Galaxy S II Android Development] Prockkaii:
Does anyone used this method with cygwin ? Cause apparently it didn't worked with me.
[Galaxy S II Android Development] carlos67:
Guys, i've searched this whole thread but can't see it anywhere. Does this kernel support init.d scripts?

[Galaxy S II Android Development] xXxJaylenxXx:
Hi all, i've been using 5.5 medium for quite awhile. I've noticed the sudden surge from 200mhz to 1200mhz whenever i turn the screen on or unlock my phone. Is it normal? Any method to reduce the possibility of the surge?

Thanks :)
[Galaxy S II Android Development] androidkid311:
I'm guessing your using on demand?? I think when it surges like that! It doesn't stay in the 1200mhz state for long. Just a few seconds. Or you could under clock it to 1000mhz. So I don't think there is nothing you can really do and I don't think its bad as such. But you can also check for any misbehaving apps :D :D.
[Galaxy S II Android Development] xXxJaylenxXx:
Hi thanks! =D I did not use SetCPU or any other voltage control apps as it has been advised not modify the settings. Is the kernel default governor is ondemand?

Setcpu should tell you how high your max frequency was set.

But CPUSpy would fit perfect too.
