Any chance you will unlock 1.4 ghz for those using tools to oc a little bit?

Great work, using the intermediate version, gonna try extreme now.
[Galaxy S II Android Development] Jokesy:
Thanks for this great kernel. I'm facing a problem when using 2.0 extreme.

Anytime I'm running graphic intense apps like HD games, my phone will either hang or reboot after 5mins.

Please help as I really prefer 2.0 Extreme to Medium version.

Thanks.

Try to flash speedmod 18 e verify if you have problems..if not, reflash phenomenal 2
[Galaxy S II Android Development] fenomeno83:
For what purpouse? Phone is already very fast and overclock wll be not apply visible performaces enhancment, bit only more battery drain
[Galaxy S II Android Development] Gall0wz:
The same reason why someone would buy a Corvette instead of a Toyota ......
[Galaxy S II Android Development] fenomeno83:
Your phone doesn't manage well extreme settings...maybe are only gpu settings that fails..there are a lot of variabiles..i made 3 versions for this reason
[Galaxy S II Android Development] poochie2:
A little more optional consumption for a tad of speed for those who feel they might need it in the most demanding tasks. Seeing how little time the cpu spends at max clock I'd give a little bit of battery for a little extra power, think of it as an insurance against the aging of the phone, a little closer to the Miui original phone.

Ps: have you thought if it may be helpful enabling the 100 mhz frequency at an even lower voltage?
[Galaxy S II Android Development] fenomeno83:
I've tried 1400mhz and there are't visible differences. Phone is already fast and smooth..at least, with speedmod based kernels
[Galaxy S II Android Development] dhrv:
so apparently i'm the only one here where init.d scripts won't load (see post #338)? :eek: or have you guys just not checked it out yet? (a good way to do this is by looking at the SD card read ahead value after boot...)
[Galaxy S II Android Development] panteleimonov:
I wrote that with speedmod 18 i havnt problems only wth phenomenal kernrl
[Galaxy S II Android Development] fenomeno83:
And reflash...maybe is not related to kernel..
[Galaxy S II Android Development] poochie2:
It's not a matter of what is best for everyday usage, it's about giving users a choice. If it is not too much of a hassle to implement it would be a nice feature as long as it triggers only when wanted and not automatically.

100 Mhz?
[Galaxy S II Android Development] Manitax:
Yeah it would be really nice if you could implement 100mhz/1400mhz support for this great kernel. It doesn't have to be enabled by default but at least give us the choice to use it ;-)
[Galaxy S II Android Development] fenomeno83:
With 100mhz will be too much jump to the second frequency: less performance and more drain.

I like all ideas of speedmod kernel: don't use hack that can drain battery or give less stability(underclock,bln,etc etc), except no undervolting support. For this reason i've created phenomenal.

With several hacks like overclock, go against goals of stability and battery.

Speedmod kernel and phenomenal are less customizable. Everything work good without customize options, but by default.

There are several customizable and very good kernels like syhia, but mine and speedmod have a different concept
[Galaxy S II Android Development] aceofclubs:
In the very 1st post fenomeno83 states very clearly the philosophy of his kernel.

Why ask for anything else? After all he made it for himself and is sharing with us.

Full source is available for anyone to mod themselves.
[Galaxy S II Android Development] panteleimonov:
same s**t :) so may be this kernel is not for me ;)

fenomeno83 what do you mean by "reflash" i flash speedmod 18 everything is ok than over this with wipe i flash phenomenal and the problems are here cant get at home screen severeal reboots befoure got the home screen .. and etc

oter known problem only for me-after flashing the phenomenall i one of the time the was made factory reset,without my command i and the second it was delete some of my apps :) and strongly and dont have such problems with other kernels.. i dont want to say that your wokr ons not good i was say that the kernel is very good for gaminsg and battery and i want to ut use it but with these problems i think is not possible..the problmes here is only with this kernel extreme and stable version
[Galaxy S II Android Development] bervin:
Your work is great op! Don't let people who clearly don't respect your decision ruin your feelings towards the contributions you've provided us here. Good work mate! Keep it up
[Galaxy S II Android Development] kartalgurhan:
apart from the uv changes, do you think the method of compiling the source would effect the battery life? if so , to what extent?

thank you
[Galaxy S II Android Development] chonshon:
Dear fenomeno83,

Would you please think about addding ondemandx governor?

Thank you.
[Galaxy S II Android Development] ithehappy:
I will try this Kernel as it's based on SpeedMod. Will try the Extreme edition as the UV values are higher than my previously achieved stable values on Ninpho Kernel, however they are different, still. Will post back my experience ;)

Users who are testing this one please DO NOT consider overnight/deep sleep drainage count to decide a Kernel, but you've to run the device at higher freq, like 1200 MHz to decide if you're getting any better juice outta this, thus play a game, or do something which pushes the CPU at higher clock rates.

Regards.

PS- I'd also like dev to add an OC option for

future use

, I am sure after 6 months we all would like to run this device at it's max extent :)
[Galaxy S II Android Development] fenomeno83:
What undervolting settings do you use usually?

try also phenomenal 2.0
[Galaxy S II Android Development] fenomeno83:
????!!!????

it is impossibile...before make a full charge to phone
[Galaxy S II Android Development] Sandwiches:
is cwm included in this kernel or should i reinstall it after the kernel?
[Galaxy S II Android Development] sageman70:
Yes. After the battery calibration. I have used Cognition 777 with this kernel.
[Galaxy S II Android Development] petrokr122:
please do it!

Guys, may be undervolting is possible to do just throw init.d script?

See link to Typhoon HD2 ROM, and explanation there...

http://xdaforums.com/showthread.php?t=933951

So, can we do it in the same way?

I think it is possible
[Galaxy S II Android Development] spirt:
thank you for the great kernel. i'm the adherent of Speedmods kernels. but your kernel has a Phenomenal battery life with the same performance on my device. i'm just on a 1st battery cycle on a newly flashed rom.

i hope you will continue to post modified versions of stable Speedmods releases. your modificaton instructions are very helpful, but i'm too lazy to patch and compile kernels myself ;)

ps: i'm on Wanamlite v5.8 a little bit modified by myself and xxki4 modem.

pps: forgot to mention. wifi, bt, gps - always on. calendar, contacs, gmail - auto sync. every hour - check for new mail and rss feeds.
[Galaxy S II Android Development] Excelsiorr:
Nice work mate.I'm glad to see your work and I apreciate that.I'm using now your kernel and my phone doesn't heat.It's great when I'm playing hd games.I need to test that a few days to see my batt life.Thank you.
[Galaxy S II Android Development] fenomeno83:
With less voltages phone will be less hot
[Galaxy S II Android Development] spirt:
the combination of the modified Wanamlite v5.8 rom and Phenomenal kernel keeps breaking my personal batterylife records. i'm still on the 1st battery cycle.

gps,wifi,bt, auto brightness and auto sync always on.
[Galaxy S II Android Development] =Dynamic=:
This kernel is very good !!
[Galaxy S II Android Development] kamandor:
What sort of modifications did you make to Wanamlite? Are you willing to share? I'm sure lots of people are interested in achieving the greatest battery life possible.

I'm at 55% battery on 8hours. Would love to be seeing the numbers you have!
[Galaxy S II Android Development] Coedy:
Is this MIUI compatible?
[Galaxy S II Android Development] fenomeno83:
No.........
[Galaxy S II Android Development] grgsiocl:
excellent kernel. been using for a day. nice battery life and i am on batista 70 foxhound. Checked the deep sleep and that too working fine. So i will stick to this kernel!
[Galaxy S II Android Development] shahulvm:
Undervolting Query

I know this kernel is undervolted, but does it give us the option to change voltages on the fly using voltage control or setcpu.

Thanks...
[Galaxy S II Android Development] grgsiocl:
This kernel is phenomenal. I flashed this kernal when my battery was at 93% and after 55minutes of heavy usage, i lost only 5% of battery. Dont wanna speak much, intsead screenshots does that!:D
[Galaxy S II Android Development] shahulvm:
I dont see any heavy usage here :))
[Galaxy S II Android Development] Coedy:
Thanks. I'll stick to Siyah then.
[Galaxy S II Android Development] panteleimonov:
like phenomenal 2 stable :) but without any problems..
[Galaxy S II Android Development] fenomeno83:
Can you Try phenomenal 1.0 e write if you have problems?...maybe problems are with gpu settings...what is your cpu 500mhz uv setting?
[Galaxy S II Android Development] qureyoon:
I'm having problems with 2 extreme as well. It's stuck at the boot logo always. Currently using Simple & Clean 2.2.1

Having no problem with medium though.

Would like to help if I can provide more info. Just let me know what to do and what to provide.
[Galaxy S II Android Development] fenomeno83:
Your cpu doesn't support extreme versiom
[Galaxy S II Android Development] ewokuk:
this is good! been saying ever since I discovered speedmod that it should have undervolting to REALLY maximise battery for those lucky enough that their hardware can handle it.

Have been using speedmod k18 test 12 for few weeks, wasnt going to update to k18 final after reading quite a few people having various issues and being happy with test 12. but going to try phenomenal 2 medium now and see if that works better than my K18 test12 :P

although ithehappy is reporting on speedmod thread that phenomenal was significantly worse than speedmod for battery. seems odd to me, if its the SAME kernal running on slightly lower voltages then how can the battery be worse at all?

edit: ok using medium, no problems so far, i ran a buggy app that I have which puts cpu to 1200mhz constantly and it didnt crash during the 5 mins I was testing it. are there any apps that will properly test stability when UV? If i can confirm that medium is stable then I will try extreme (provided medium actually shows an improvement over the k18 test12 I am coming from, which so far it doesnt as battery seems to be dropping like a rock, this is either due to k18 final being worse than test 12, or due to phenomenal, no idea which).

Results for SpeedMod / void / Phenomenal / 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 XWKK5 ROM (Modem: XXKI3).

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

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

Running void.echo kernel, I used the default settings, and only enabled „Auto CPU UV on boot“.

Just added battery saving results for Phenomenal 2.0 Extreme version.

Here are my current results:

Benchmarks

Battery stats

How, Phenomenal 2.0 Extreme version has even better battery savings on my phone than Medium version.

And it is smooth and stable - on my phone.

That's why it became my new favorite.
[Galaxy S II Android Development] fenomeno83:
can you repeat test with phenomenal 2.0 stable? thanks ;)
[Galaxy S II Android Development] fenomeno83:
guys, what do you think about change freq table from

200 500 800 1000 1200

to

150 450 750 1000 1200

?

ps: don't touch maximum frequency! I bought a 1.2ghz dual core phone and will remain 1.2 ghz phone! :D

(you can reduce via script/setcpu or similar maximum frequency if you want)
[Galaxy S II Android Development] ewokuk:
make it and call it super extreme?
[Galaxy S II Android Development] Manitax:
It would test it ;-)
[Galaxy S II Android Development] fenomeno83:
i'd like make a new phenomenal version (2.1) with normal/medium/extreme...

should be a test version to understand if reducing frequency of 50mhz in some steps doesn't affect performances in use and is more battery friendly

after, i want understand if speedmod k18 base is really more battery friendly of k16 base (used in phenomenal 1.0/1.1)

@it_ler, can you remake battery test with phenomenal 1.0 extreme, after remaking test with phenomenal 2.0 stable? IF YOU HAVE TIME, AND YOU YOU WANT..

@panteleimonov, can you test phenomenal 1.0 and tell me if you have problems?
[Galaxy S II Android Development] pissyhun:
this could be magic if u do it. after all u are fenomeno... i think undervolting and the lowest freq in deep sleep is the key. so if u can put it 2 versions:

100 450 750 1000 1200

150 450 750 1000 1200
[Galaxy S II Android Development] bervin:
i think min freq a 200mhz is fine cause if not it will cause a frequency jump too often and besides at 200mhz i can uv to 800mv but at 100mhz i can go to 775mv not much difference from 200mhz might as well stick to it since we can do more stuff at 200 without jumping freq
[Galaxy S II Android Development] fenomeno83:
100 is too much low in my opinion..and not all phone manage well this frequency...is low also because jump to the second frequency became higher (against performances and maybe battery)
[Galaxy S II Android Development] It_ler:
Hmm ... I always want to flash and test new kernels.

But I have just flashed Intratech's XWKL1 Frankenstein ROM.

So, my upcoming tests with SpeedMod and/or Phenomenal kernels will no longer be "comparable" with the test results on XWKK5.

I will start testing Phenomenal 2.0 Extreme version on XWKL1.

After finishing my tests and posting my results, we can talk about what to test next.

Hope that I can support you by doing some tests and providing results that you can use to enhance your kernel.
[Galaxy S II Android Development] fenomeno83:
If I change frequency, I don't change algorithm to manage jump frequencies..

so, if for example is set jump from 200 to 500mhz after load > 20%, now jump from 150 to 450 will remain after load > 20 % (this is only an example)

is different if you add another frequency in table(for example 100-200-500-etcetc), you must change also algorIthm tHAT manage frequency table..

and, power consumation depends from frequency and voltages (C*f*v^2); so, if you use same voltages at lower frequency, you will drain less battery

but I want to do this version for test to know about battery benefits without loss performances
[Galaxy S II Android Development] fenomeno83:
ok..I'd like know about phenomenal 2.0 normal in comparison to speedmod expecially..phenomenal 2 should be stay under phenomenal 2 medium as battery scores.

and, some people report that prefers 1.0 as battery saving, for this reason I want understand if k-16 base is more battery friendly of k.18.

My goal is find best balance between battery and performance, without loss stability. For this reason after several test versions, i can make phenomenal final version.

I think that with samsung update 3 kernels based, we are at limit.
[Galaxy S II Android Development] Karpfenhai:
Hello again, don't know whether my opinion counts but after 3 days of testing ph 2.0 ex i just went back to 1.0 ex .

the 2.0 kernel works flawless, no question, no issues, no random boot, nothing, but.. weird battery consumption behaviour.. :-( it eats more power than your old kernel, even after a "settle-cycle", I'm on villain rom 3.0 and KL1	modem.

If i use my phone i can watch the battery dropping during normal operations like browsing or tapatalk, on 1.0 this is not the case. Yesterday i lost 29% battery in 6 hours with flight mode enabled and not using the phone at all! Yes, i can read BBS, no unexpected wakelocks and stupp, phone was on deep slerp.., Never had such effects on 1.0.!

conclusion, test 16 works much better for me, so i will stuck on Phenomenal 1.0 at least for a while.

regards.

Swyped from my GT-I9100 using XDA App
[Galaxy S II Android Development] fenomeno83:
ok...can you do this test? test phenomenal 1.0 ex and after reTest phenomenal 2.0 ex...
[Galaxy S II Android Development] ewokuk:
right im now testing extreme. was not impressed with medium, battery seemed to be just draining for no reason. however before putting extreme on I wiped cache and dalvik and so far that seems to have stopped the excessive drain, still not sure its better than k2-18 test 12, but I would assume its better than k18 final assuming its identical but with lower voltages.

needs a couple more days of testing as I havent really used it yet but looks promising after the wipe.

so anyone having any problems, if you dont wipe cache and dalvik, you are probably wasting your time testing anything, EVEN between different versions of the same kernel (plus it takes like 2 seconds to wipe it anyway so not exactly difficult).
[Galaxy S II Android Development] Mayday_XL:
The extreme version runs fine, thanks.

[Galaxy S II Android Development] ewokuk:
ok using extreme, 10 hours overnight with 3g on and sync on 2 email accounts. I only lost 5%, new record for me, slightly better than my old K2-18 test12. keeping this as long as I dont get any crashes. nice.
[Galaxy S II Android Development] hansation:
hi, im a a fan of speedmod. this is my first time to try v2.0 extreme. do i still need to uv this kernel? or do i need setcpu or voltagecontrol to uv? thanks
[Galaxy S II Android Development] ksantoshh:
Bro.Please read through the first page of the thread. The kernal is already UV by 100mv at each frequency step.
[Galaxy S II Android Development] pro.aggro:
Is there a way to make a recovery update on v5.0.2.7 and a cwm manager update on v3.0?
[Galaxy S II Android Development] borrego:
IMO it is better to keep the stock SpeedMOD CPU hot plug settings. As I find the Touchwiz UI, and browsing internet (on Wifi at home) a lot less smooth and slower with the stock Phenomenal 2.0

I think if staying in single causes longer webpage loading time, it may actually uses more battery with longer data connection time?
[Galaxy S II Android Development] didopidobg:
Absolutely same here. Pheno 1.0 Extreme is ultra battery saving, I expected even better results form Pheno 2.0 but who knows? Maybe fenomeno will try some improved 2.x version. I love this kernel!
[Galaxy S II Android Development] fenomeno83:
are you sure? try to set loadH to 60 by script and retest

Phenomenal 2.0 Extreme version performs very good on XWKL1 ROM - on my phone.

Not much difference to same kernel on XWKK5 ROM.

So, it is still my favorite.

Maybe I will redo some other kernel tests on my current ROM.

EDIT:

I had one freeze with Phenomenal 2.0 Extreme version. As I could not reproduce the issue, it could be a one-time problem.

Will examine the kernel for a while and report if any issue/freeze/FC occur again.
[Galaxy S II Android Development] fenomeno83:
Thanks! Sorry, can you test phenomenal 1.0 extreme? Some people reports that has better battery of 2.0 extreme
[Galaxy S II Android Development] shahulvm:
Am able to easily clock 2+ days of moderate use with ver2.0 extreme edition...perfectly fine with it..:)
[Galaxy S II Android Development] It_ler:
Ok, for you my friend, I will flash and test Phenomenal 1.0 Extreme ;-)

EDIT:

On the first look does not feel as smooth as SpeedMod K2-18 based kernels.

And I had one freeze during benchmark testings.

But my first benchmarks show nearly the same scores for Phenomenal 1.0 and Phenomenal 2.0 kernel.

Now I am curious about its battery savings.

Will post my findings as soon as my tests are finished.

---------- Post added at 10:47 AM ---------- Previous post was at 10:44 AM ----------

I had 0% battery drain/loss in 9 hours during nightly airplane mode running Phenomenal 2.0 Extreme version on XWKL1 ROM.

Absolutely amazing !
