Tried Black Phenomenal 2.1 Medium, ran it for a few days but it's not giving me the same battery life I got on 2.0 Medium. On 2.0 I had 6+ hours of screen on time over 24 hours, but on 2.1 I max out at 5 hours, over 14 hours. Of course, this is in no way a scientific comparison but I think I'll be switching back to 2.0 Medium.

i'm trying this kernel. but i get a heavy battery drain. i'm at the first battery cycle with this kernel (i wipe battery stats). i'll post screenshots after 2-3 cycles. in 6 hrs i lost 36% of battery without data of wifi. only 13 sms, 2 mins of call and 3 mins of angry birds.

i don't find the post with the guide for custom bootanimation with speedmod kernel. can you post the link?

ps: thank you for your share

thanks fenomeno83 for this thing (i don't call this kernel) it makes my battery paused at certain level. i've been using my phone for 9 hours with bluetooth headset (about 5 hours usage) and several phone calls and it's 94% here :D

thanks again for such a great "thing" :)

not as battery efficient as Speedmod k2-18 test7

Hi fenomeno...thnx for the kernel..i was trying to benchmark this kernel with speedmod k2-18 test7 and i found the test7 to be more battery efficient than this...

But i am sure with the next version of speedmod kernel and with your undervolting...we would be able have win here...

Hi fenomeno83

I'm trying to learn UVing. Have a beginners question:

What are the differences between cpu arm voltages and cpu internal voltages?

If I use Voltage Control, the value that were displayed is which voltage value?

Thank in advance.
[Galaxy S II Android Development] a1adin:
at first, I use the exact same script in the 1st page:

then I change the max value to 800mhz using the text editor in root explorer:

Results for SpeedMod / Phenomenal / void / N.E.A.K. / stock kernels

Everything is specific to my phone, my "normal" usage and my home location. Most values are exact results, but some are rounded. I usually have wifi, synch (three email accounts, calendar and news), Google Talk and Skype on.

For all custom kernels, I was running on Frankenstein XWKL1 ROM (Modem: XXKL1).

For stock kernels, I was running on the corresponding stock ROM.

Always using the Samsung's standard / stock 1650mAh battery.

Finished my battery tests for Phenomenal 2.1 Extreme blue version and added its results.

Here are my current results:

Benchmarks

Battery stats

On my phone, Phenomenal 2.1 Extreme blue has nearly the same battery savings like black version. I can't see a significant difference.

Phenomenal = SpeedMod-based with UV is still the best-balanced kernel on my phone.

But I will keep testing new kernels ...
[Galaxy S II Android Development] paulyluca:
Not a bad screen on time for 2.1 extreme. Could have been even mor, but it was a day of heavy use, because my Laptop is in service, so I did everything trough my phone: emails, browsing, messaging, synking etc. Even 30 minutes of gaming.
[Galaxy S II Android Development] Fishawy:
Hello mate,

Can you please add this one to your tests?

[Galaxy S II Android Development] Manitax:
With setcpu and voltage control you change cpu arm voltages.

But Phenomenal or speedmod do not support that.. you have to use N.E.A.K. , syiah or other supported kernel.

Internal voltages perhaps change the Bus freq?? but i dont know..

Cheers
[Galaxy S II Android Development] kxnzxmori:
Testing this kernel now. Let's see how it goes... If it provides gd batt results on my phone, i'll stick with it. :)

Coming from speedmod k2-18.
[Galaxy S II Android Development] grgsiocl:
its a stock kernel and may not yield better results than any other available kernels. I guess by going through the test reports, phenomenal 1.0 is doing good in terms of battery.

My experience

-------------

Siyah newest version: video calls lag, doesnt run thunderbolt scripts etc...and also voice quality is not good too

neak kernel: same problems like above

phenomenal: excellent for my usage and runs smoothly without any problems!
[Galaxy S II Android Development] It_ler:
CF-Root kernel for XWKL1 ... as another user said before, CF-Root is a rooted stock kernel (in this case XWKL1 stock kernel) ... Chainfire only added some "little" features (SU, BB, CWM, etc.).

But nothing to change performance or battery life.

If have already tested XWKL1 stock kernel.

P.S.:

If you meant to test kernels on TurkBey ROM: I want to stay as close to stock / Samsung ROMs as possible. That's why I do not flash custom ROMs.

Are you running a 64 bit ubuntu?

Please make sure you install everything that is stated here:

$ sudo apt-get install git-core gnupg flex bison gperf build-essential \

zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs \

x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev \

libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown \

libxml2-utils xsltproc

If some parts are not installing do copy the single packages in your terminal and install them seperately.

Then install this package:

$ sudo ln -s /usr/lib/i386-linux-gnu/libX11.so.6 /usr/lib/i386-linux-gnu/libX11.so

I hope this helps. These are the required packages for building a kernel from here:

http://source.android.com/source/initializing.html

You probably do not need all of those packages, but install them just to be sure.

@fenomeno83: I think you can stop making the blue version, the black version is a lot smoother and according to it_ler tests the battery savings are similar. I've just changed from extreme blue to extreme black (both stock frequencies) and I find black a lot smoother.
[Galaxy S II Android Development] Lownita:
Hi

Does this kernel (black) give exactly the same performance as speedmod k-18? It is ONLY uv, so performance should be the same, right?
[Galaxy S II Android Development] dica:
Yes
[Galaxy S II Android Development] It_ler:
In theory: Yes.

Same kernel = same performance.

(Assuming that the same governor is used.)

But it is hard to proof/test because benchmarks often test special parts of the firmware (browser, OpenGL, CPU, GPU, etc.). Some of them are ROM related and should never differ between different kernels as long as the ROM remains the same.

I often have slightly different results is benchmarks even between SpeedMod K2-18 and Phenomenal 2.0 (which is also SpeedMod K2-18 based).

Maybe some benchmarks are having a bit trouble with UV and therefore they show less score?!

Sometimes it is better to not only trust benchmark results but just use the phone as "normal" and check if it runs smoothly or not.

Thanks Schindler for your time, I have downloaded all 3 zip correctly, however while compiling I always end up with the same error. ie ubuntu and mint linux.

What I had done :

1. Installed Mint Linux 12

2. Installed required patches

3. Installed all packages listed for 64 bit from http://source.android.com/source/initializing.html

I did not install two packages ie. lib32readline5-dev lib32z-dev

i) Note, selecting 'lib32z1-dev' instead of 'lib32z-dev'

ii) However for lib32readline5-dev , it requires a different built. All requirements taken care..

Appreciate your time and help..If you can pm me your chat-id, then it would make it easier....or even fenomeno..

Thanks much guys..

Coming from 2.0 extrem i flashed 2.2 black extreme. Everything is running fine,no lagging with Modern Combat 3, no freezes or reboots.

Great kernel!
[Galaxy S II Android Development] markp1989:
I have been noticing a rather odd problem since I have flashed this kernel:

my phone is sitting on the desk next to me and it keeps making the "ping" noise it makes when you plug it in to the charger with the battery full, and the battery icon on the status bar says the phone is charging, even thought it is unplugged.

it seems to be randomly jumping between "plugged in" and "not plugged in" even though it is not plugged in, I can Imagen this will cause problems with battery life as there is a kernel wake lock that only comes active when the phone is plugged in.

The battery is still reading at "100%" as it hasn't been unplugged very long (about 2 hours)

edit: if i go to the "status" page under settings, I can just see the "Battery Status" field jumping between "discharging" and "charging(usb)" every 3-10 seconds

edit: I tried rebooting the phone, and it wouldn't turn back on, was coming up with a picture of the battery with a spinning circle on it, I tried booting in to cwm and clearing the battery file, which let me turn the phone on ok, reported battery life dropped from 100% to 82% from clearing battery file.

any one else had any problem like this?

edit again: I just tried cleaning the charging connector with cotton wool tips, and the its been about 15minutes and this problem seems to have gone so far, I will report back in a few hours to see weather it has happened again.
