I think it'd be great if you could also compile a more aggressive version (more UV) and post it here.

many thanks, trying now.

[Galaxy S II Android Development] stylez:
Moved to correct place.. :)
[Galaxy S II Android Development] fenomeno83:
I will share a guide for dummies that explain how compile kernel with favourite values
[Galaxy S II Android Development] GIRIDEGR8:
you have interchanged the links in the CWM and Odin version Megaupload links, CWM link opens Odin version..

the kernel seems to be good , no percentage drop in the last 2 hrs idle. will keep you posted on how it is over the time. Thanks for the nice work
[Galaxy S II Android Development] sageman70:
Initial impression: tried it and it drained my battery by 7% in 5min although the phone was on stand-by.
[Galaxy S II Android Development] sid9922:
Just flashed this kernel with the new Turkbey v.29.2..after 5hrs i can say that i have huge improvement with my battery life than the other kernel that i tried..no setcpu.voltage control and anything else..

I just have some lags while browsing the homescreen and app. drawer though..im using Go Launcher Ex..any tweaks to get rid of the lag?

Thanks in advance guys..
[Galaxy S II Android Development] pissyhun:
hi i'm back with some results. xwkk5 stock rom+ xxki4 modem+phenomenal 1.0

i use init.zip made by frankcilo.

battery - 32%- 1 day 4h , display- 45%- 4hours.

very stable kernel, no fc and no restarts.

i think this is very good but i think that are much more kernel wakelock with this kernel than speedmod k16. i am not an expert. i use betterbatterystats.

today at 1% battery life i will try phenomenal 1.1 and init.zip made by frankcilo.
[Galaxy S II Android Development] kungvn:
After 11 hours, I have 64% with my battery, 2h30 screen on : with sms, web, mini game: fruit ningia, one billion, :D

Not bad. Right?

P/s: check rom v4 with phenomenal 1.1

sr my bad English :D
[Galaxy S II Android Development] BossNexusS:
Yeah........ Don't use Go Launcher.. Lol! It's a huge waste.. TWlauncher is by far the best and smoothest!

[Galaxy S II Android Development] ziroxs:
In the meantime i tested echo.void and some other kernels, but [1.1] without setCPU or Voltage Control rulez them all.

Using now simply & clean with this kernel, great job. with the new 2000mAh battery from samsung 5-6 days will be real.
[Galaxy S II Android Development] BossNexusS:
I have a question is anyone else getting unusually high battery percentage from Android OS? Mine is always at like 20%.. On other roms it's usually at like 4%.. Does anyone know why?

Sent from your bedroom with my GT-I9100
[Galaxy S II Android Development] pissyhun:
mine is 16% i think because of wakelocks...
[Galaxy S II Android Development] riccardoPolaris:
Don't worry new kernel will normalize voltages

CheckRomRevolution HD v4.0

Kernel Phenomenal v1.1
[Galaxy S II Android Development] riccardoPolaris:
This is not real problem in This kernel because it isn't battery drain.

Try and write your experience. Look

CheckRomRevolution HD v4.0

Kernel Phenomenal v1.1
[Galaxy S II Android Development] bervin:
@fenomeno

maybe you can try to take void kernel and add extreme uv??
[Galaxy S II Android Development] pissyhun:
hi

some results of phenomenal 1.1. i wil post a picture that made my day very good. first of all kernel is very stable and smooth, no fc, no restarts, undervolting is ok.

in quadrand i also got 4000 points so its ok but i wanted to flash this kernel for battery life and i see that performance didn't drop too much.

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.

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“.

Here are my current results:

Benchmarks

Battery stats

Thanks fenomeno83 for your good kernel.

Benchmark results are not the best, but battery savings seem to be better.

I will finish my testings and then post all results.
[Galaxy S II Android Development] pissyhun:
hi

anyway who uses this kernel i think it's for battery life because of the undervolting process. undervolting will cause a decrease in performance. so quadrant and nenamark don't mean nothing.
[Galaxy S II Android Development] aqualeris:
Not necessarily.. Stability is an issue more often related to undervolting than performance. Underclocking, rather, would directly impact benchmark scores more than undervolting would..
[Galaxy S II Android Development] fenomeno83:
Thanks for your benchmark!

Consider that is based on "old" speedmod k16..when hardcore will release new final version, i will make a new phenomenal version.

Phenomenal will have same performance of speedmod used as base, but more battery (thanks to undervolt)

another thing: phenomenal 1.1 is a "test" version. The stable is the first 1.0 (not extreme version)

;)
[Galaxy S II Android Development] fenomeno83:
Not correct.

again, consider that phenomenal is based on an old speedmod version...performance will be not affect.. performance ARE THE SAME OF SPEEDMOD K16

Undervolting is a process which reduces the excess "voltage" given to the CPU using a software..is different from UNDERCLOCK (reduce performances) ;)

Another thing: I'm not a fun of benchmarks, that can give only an idea of performances/battery life.If you repeat many times benchmark, results will be always different. In real use users can understand how a kernel work.
[Galaxy S II Android Development] It_ler:
As I tested many SpeedMod kernels and only some other custom kernels, such as Phenomenal 1.1 and void.echo, I have posted my comparison result list here => http://xdaforums.com/showpost.php?p=20201903&postcount=5680

After next stable/final version of SpeedMod and your undervolting add-on, I may test the new Phenomenal kernel as well.
[Galaxy S II Android Development] pissyhun:
hi

thx for info about undervolting and underclocking. glad that u want to continue work on this kernel. waiting for the next final release of speedmod to see another phenomenal kernel.
[Galaxy S II Android Development] xcarecrow:
Please, can you consider to make a Phenomenal version with speedmod 18 test 12? it seems it's the best version at the moment.

thanks in advance!
[Galaxy S II Android Development] fenomeno83:
thanks....... ;)
[Galaxy S II Android Development] fenomeno83:
i think that when hardcore will release final version, it will be based on the best test kernel.

And hardcore will publish source code when will release final version..i can't compile a new phenomenal if I haven't source
[Galaxy S II Android Development] jonny68:
may i ask which kernel based on your tests you recommend for best battery life?
[Galaxy S II Android Development] Jeremy:
Hey man, great job on 1.1. Awesome battery life. Lag free.
[Galaxy S II Android Development] JPHCCFC:
I tried phenomenal kernel last night but it kept vibrating during charging even on silent. Is this normal behaviour? I reverted back to siyah but will re flash phenomenal if it was due to a bad flash. Was on checkeom v4
[Galaxy S II Android Development] It_ler:
Difficult to say as the same kernel will have different results on another phone.

On my phone, SpeedMod K2-18-test10 had very good results running on XWKJ3 ROM.

And SpeedMod K2-18-test12 had very good battery results on XWKK5 ROM ... on my phone.

Depends on so many things ... I recommend to test it on your own - on your phone with your settings at your location and with your "normal" usage.
[Galaxy S II Android Development] nursespecialist:
Hi. I would like to ask the font your using and where can i get it? Thank you so much
[Galaxy S II Android Development] hanifh:
since flashing this Kernel, Market has stopped functioning over wifi and Eva intern app very erratic. Also, LauncherPro's app drawer blanks out and a reboot is need for them to be restored. standby battery time seems to be very good.
[Galaxy S II Android Development] Karpfenhai:
No such side effect here, have you wiped the cache partition and dalvik?

Cuz, new kernel needs to recompile desired apps, maybe market and launcher..

try wiping both and come back after, note, first boot can take up to 5 mins then, good luck!
[Galaxy S II Android Development] Jokesy:
I'm currently using this kernel version1.1 and it works great without any problem with KI4 and KL1 modems.

BUT I must say it has problems with KI3 modem because anytime I flash this modem to my phone the loses stability and just reboots under heavy use. Flashing back to KI4 or KL1 modem solves the problem instantly!

I'm on Android 2.3.6 XXKK5
[Galaxy S II Android Development] aceofclubs:
Was using this 1.1 kernel on KJ3 with KI3 modem without any problems.

Might be a combination of things in your device. Each device is different.
[Galaxy S II Android Development] pedestre:
I confim that I've been using this kernel (extreme edition) with ROM KJ2 and modem KI3 and no problems at all.
[Galaxy S II Android Development] pasquy85:
Did you also try 1.1? If yes,any difference in battery saving?

Anyway I hope Hardcore will release soon a new final version with sources so as to see a new phenonenal mod!
[Galaxy S II Android Development] pedestre:
Yes I did and I can't tell any difference in battery saving.
[Galaxy S II Android Development] Jeremy:
This kernel is not getting the love it deserves. Very good stuff. Using 1.1 extreme with Checkrom rev 4. Excellent.
[Galaxy S II Android Development] Karpfenhai:
full ack, its awesome, my no. 1 recommendation to all my friends!
[Galaxy S II Android Development] pedestre:
+++++++++ I totally agreeee +++++

This kernel will improve even more when hardcore releases a new stable version. Test12 is a great kernel in battery saving but no sources yet.
[Galaxy S II Android Development] aceofclubs:
Using XWKK5 firmware with KL1 modem and this extreme v1.1 kernel with no problems whatsoever at this stage.

Thanks for a great kernel.
[Galaxy S II Android Development] Jeremy:
Hey man please keep this baby updated. Love your work.
[Galaxy S II Android Development] Manitax:
I'm waiting for a new release. Hope that hardcore publishes his source soon ;-)
[Galaxy S II Android Development] kungvn:
+1 :D:D but I think Phenolmenal 1.1 is enought because it's the best :D ( with me)
[Galaxy S II Android Development] rj.camargo:
Agree. I could stay with phenomenal 1.1 for ever can't find something to be improved.

phenomeno83 keep up the awesome work.
[Galaxy S II Android Development] andrei_me:
quick question. i wanna try this kernel. do i use setcpu? governors? oc or uv? thanks. :)
[Galaxy S II Android Development] Manitax:
The new speedmod test 17 kernel seems to be awesome in performance and batterylife! With uv it would be even better!
[Galaxy S II Android Development] Karpfenhai:
just read the thread... setcpu is supported but not needed.. the kernel is a full undervolted piece of art :)

only stock (speedmod) governors are included, i suggest to stay on ondemand, use setcpu only to control the max speed, resign using profiles, they are not neccessary w/ this kernel!
[Galaxy S II Android Development] Mujodroid:
i will test it for 2 days

thanks
[Galaxy S II Android Development] bernard134:
No problem, you will fall love with it after that. ;)
[Galaxy S II Android Development] pedestre:
Hey guys, new final version of speedmod kernel (K2-18). I can't wait for phenomenal 2.0

How many charging cycle to have most efficient battery life? Because on my first charging cycle ive got 30% drop on the first 3 hours. I used the phone for sync 6 gmail(active mailing list), twitter and browsing..
[Galaxy S II Android Development] DaveHTC200:
My battery savings were instant!

Have you tried bbs to see what wake locks you are getting? :)
[Galaxy S II Android Development] greyrevolver:
I already install bbs, but honestly i have no idea how to read the result :)..
[Galaxy S II Android Development] pissyhun:
hi

first of all u must know that all different kind of mails and twitter or other programs that run in the background consume more battery. first the telephone not going in deep sleep. wifi or 3g also consume more battery. so 20-30% drain is ok if u use the programs u said. bbs has one option- partial wakelock its a list and there u will find which programs consume your battery. install bbs and use google.it takes me 1-2 days to understand bbs. look here on xda because there are some threads about bbs and wakelock.

Updated to newest speedmod kernel k2-18

Hey guys since fenomeno83 did not match his kernel to the newest version of hardcores speedmode kernel (k2 18), I tried it by myself.

I did nothing more than just follow fenomeno83 guide how to undervolt the kernel which you can find in the first post.

I decreased all the bus, internal and gpu voltages by 50 mV like fenomeno83 did in his kernel. If you want I can send you a link to my undervolted speedmod k2-18 version. Just pm me.

Remember I did nothing on my own! I just used hardcores newest sources and the very good guide from fenomeno83.

@fenomeno83 thanks a lot for your guide!
[Galaxy S II Android Development] fenomeno83:
Next weekend will publish new phenomenal..i'm full of work in this moment
[Galaxy S II Android Development] pedestre:
Why don't you simply upload it and put the link? Everybody could test it without bothering you.

Just an idea
[Galaxy S II Android Development] Schindler33:
Yeah I know, but I want to ask fenomeno83 first.

EDIT: I got the ok from the boss.

Here is the link for the undervolted speedmod kernel k2-18.

Remember I only tested it on my device, however it was stable. I am not responsible for any damage you, or this kernel will do to your phone. You flash it at your own risk.

- Test1 is only slighty undervolted. 50 mV on bus, cpu and gpu.

- Test2 has some more cpu undervolting and -50 mV on bus and gpu:

1200 MHz@ 1175 mV

1000 MHz@ 1075 mV

800 MHz@ 975 mV

500 MHz@ 900 mV

200 MHz@ 850 mV

All credits go to fenomeno and hardcore!

Flash via CWM recovery.

Hi Shindler, are those cpu voltages for test1 or test2. If for test1, then can I have the values for test2 pls....thanks
[Galaxy S II Android Development] kungvn:
I think test 2 :D
[Galaxy S II Android Development] aceofclubs:
Test 2 is working great for me so far. thanks a bunch mate.

Quadrant score 4016 for what it's worth.

No errors with setcpu stress test. Whatever that does.

All equals....phone works good.
[Galaxy S II Android Development] pedestre:
Same here.

Thank youuuuuuu
[Galaxy S II Android Development] Schindler33:
These values are for test2. Test1 is -50 mV on everything.
[Galaxy S II Android Development] mb:
Still the best Kernel on the SGS2 by far. Thanks to Schindler33 for taking the initiative to make an updated version.
[Galaxy S II Android Development] ziroxs:
Its too short for a good analysis but a battery drain of 7% in the last 9 hours with permanent 3G on (receiving ~ 20 mail messages) and using telephone over bluetooth for ~ 30 minutes sounds very good.

Using the Test1 Kernel. ;)
[Galaxy S II Android Development] RedSpyderX:
will this work with CM7>?
[Galaxy S II Android Development] Mujodroid:
Hello good morning/evening ,

this my result of 2 days testing the kernel W@@W so far ,

around 15h battery 15% & display on 3h :D

Thanks :cool:

I tesedt schindler kernel test2 but phenomenal kernel is far superior battery wise
[Galaxy S II Android Development] wicked245:
Which karnel phenomenal or schindler test 1 or test 2?
[Galaxy S II Android Development] ziroxs:
I think 1.1 oder 1.0 because the other kernel compiled by schindler33 is only 1 day old :o
[Galaxy S II Android Development] markp1989:
Would it be possible to add "2nd core" support to this kernel?

http://tegrak2x.blogspot.com/2011/11/2nd-core.html

it gives the ability to turn off one of the cores to save extra battery life.
[Galaxy S II Android Development] ckfamily:
turn off 1 core??, why bother to buy a dual core phone at all?
[Galaxy S II Android Development] markp1989:
I didn't mean to turn 1 of them off all the time.

you can set 3 modes:

you can have it auto turn the 2nd core off when the load is light (which the phone does by default anyway)

you can force both cores to be on

you can force 1 core to be off.

I can see the use if your going to be away from a plug for a long time, thinking on holiday etc, just to squeeze as much time as you can out the battery.

I agree that having 1 of the cores off at all times would defeat the point of getting a dual core phone, I would just like to be able to manually chose

I guess I'm just a bit of a control freak.
[Galaxy S II Android Development] Manitax:
+1 that would be cool ;-)
[Galaxy S II Android Development] shahulvm:
If you dont want the second core to be kicking in often, you can do this...

echo "80" > /sys/module/pm_hotplug/parameters/loadh

echo "40" > /sys/module/pm_hotplug/parameters/loadl

Loadh --> instructs the second core to kick-in only when the first core is above 80% threshold

Loadl --> instructs the second core to go off-line when the first core load reaches 40%

Those are hot-plug modules params

@Mujodroid

Please try the Test1 kernel. I know, the UV in test1 is less than in test2 but i get a great performance with the first kernel from schindler33.

Lost 12% in 24 hours (8 hours flight modus, 35 minutes telephone via bluetooth, 16 hours 3 G Modus and getting ~30 mails with google mail sync).

@shahulvm

Thank you for sharing this info. What are the standard values if i want to have default parameters? Or they will be switched back after rebooting?

thx

Does someone knows if its possible to UV/UC the GPU with the last final speedmod?
[Galaxy S II Android Development] Karpfenhai:
finally i found a possible Issue w/ the Phenomenal 1.0 Kernel, if the Phone is deep sleeping on airplane mode it seems the bell is not ringing, means the alarm in the morning does not wake up the phone (and me!!), if i press the home button the alert is showing on snooze and after the snooze period it raises as expected, that's kinda weird.. if the phone is on charger the alarm pops up as expected, if the alarm is set to lets say 30 mins (short nap during lunch) it works fine too, even on flight mode, so only after a long period of sleep w/o being attached to power (more than 2 hours) its broken, so sound, no screen on.. does anyone else have similar issues with that?

confused greetings..
[Galaxy S II Android Development] ziroxs:
My wake up in flight modus works very good. With [1.1] and the new Test1 schindler33 kernel as well. No problems here with this combination.
[Galaxy S II Android Development] shahulvm:
Put the above values in a script and place it in /system/etc/init.d folder

Removing those lines and rebooting will have the values reset to the default ones
[Galaxy S II Android Development] ziroxs:
Hi shahulvm ,

i already tried this yesterday but without success.

I copy and renamed a file from the inid.d folder and add this parameters. Executing this file changed the configuration, thats ok. But a reboot doesnt change anything.

I also add a sleep 30 command in it, to do it later after reboot, no success as well.

Perhaps my FluxMod do not support the init.d scripts?
[Galaxy S II Android Development] Schindler33:
I tried to patch the kernel with the patch Tegrak provides, but it failed.

Does somebody know how one can make a kernel compatible with setCPU?
[Galaxy S II Android Development] shahulvm:
Wrong Post
[Galaxy S II Android Development] aceofclubs:
@schindler33

I've been using setcpu with your test2 kernel all day and it appears to be working ok.

Not voltage...but clock speed looks ok.
[Galaxy S II Android Development] Schindler33:
Yeah sorry i meant controlling the voltages too. Clock speeds are working well
[Galaxy S II Android Development] markp1989:
I just took what you said and made it an init.d script, gonna do some tests to see if it makes any difference to the battery life.

#!/system/bin/sh
loadh="80"
loadl="40"
echo $loadh > /sys/module/pm_hotplug/parameters/loadh
echo $loadl > /sys/module/pm_hotplug/parameters/loadl
[Galaxy S II Android Development] ziroxs:
Ok, i make a big mistake. I forgot to rename the script and put the "S" in front of the name :o sry

Now it works
[Galaxy S II Android Development] shahulvm:
Am not sure what the issue is, but test2 shows high utilisation of "Android system" in idle mode....so am switching kernels...:p
[Galaxy S II Android Development] fenomeno83:
default loadH is 60 and loadL 20.

Today or tomorrow i will release phenomenal 2.0
[Galaxy S II Android Development] fenomeno83:
have you tried this params? performances remains the same in several context (browser, games, etc etc)?

I thought to set these as default params in my new kernel
[Galaxy S II Android Development] ziroxs:
What ROM you are using? I have a very less android usage using test2. After 12 hours standby with permanent sync of one googlemail account and 3G still on.

- Android OS 16 min (18%)

- Android System 4 min (8%)

- Dsiplay on 40 min (47%)

@phenomenal83

I had no time to test the cpu parameters with applications. btw my are a little bit different :D 80/55 and i could not see any issues. Yesterday i streamed over 1 hour internet radio over WLAN and lost 7% accu power.

Battery life is excellent.

[Galaxy S II Android Development] shahulvm:
fenomeno, as for me the performance is good for general use... i usual dont play games, but browse the web etc(ie you tube, tweet, fb, mail, streaming) ...you could first give it a try and then check...but it greatly reduces the second core becoming online soon..
