thanks mate, this steps I've thougt by myself too. I've already tried with clerar the cache and dalvik cache. Now as a first step I've re-installed the SetCPU and let only start it at boot with the full frequency range (200-1200). It seems, it solved my problem for now. Once I have time, I'll do the factory reset and the others...

Results for SpeedMod 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.

I am running on Frankenstein XWKJ3 ROM and Samsung's standard 1650mAh battery.

Here are my current results:

Benchmarks

Battery stats

Test12 seems to have the best battery savings for me (on my phone and my "normal" usage). I conclude this as the ratio between battery loss per hour and screen on time is the lowest = best.

Test10 has got the best balance between battery savings and performance for me (on my phone and my "normal" usage).

So, thanks again to hardcore for providing another "top" kernel !
[Galaxy S II Original Android Development] lrcquest:
Wow, that is some test result!!
[Galaxy S II Original Android Development] grisha1:
Thank you for this helpful comparison.

I dare to ask you. Could you include a test with void. echo with the same conditions? That would be interesting.

For me k17 still brings best battery performance on stock ki8 deodexed, went now back from test 11
[Galaxy S II Original Android Development] It_ler:
Maybe ... depends on what you mean by "void. echo".

Can you explain or describe it to me?

EDIT:

No, I won't test other kernels ... yet.

Sorry, but you have to do it yourself.

K2-18-test8 quite well results.

Hi,

before to start with this mod kernel I was using Siyah 2.1 Kernel and then

I got several card mountin problems for external and internal memory, but since I've installed K2-18-test8 all my problems has gone.

The kernel works smooth and the battery is a little bit better.

Good works Hardcore!!!.

Can someone give a link with the Odin version of: K2-18-test10 for my next tests.

I can't update kernel from the CWM Manager V2.0 installed with the Carbocean V6 Rom.

Thank you very much.
[Galaxy S II Original Android Development] tCC:
thanks a lot for the statistics, very cool ! switching to SpeedMod again because of your info :D
[Galaxy S II Original Android Development] nikzDHD:
Test 12 is fantastic deep sleeps very well even with push email I have both my gmaii and exchange pushing and does wonders.

I've flashed many kernels before but always come back to this as it just works without tinkering, this is like Apple plain, simple and works. Others are like android although they work well you need to tinker until it's right for you which is not a bad thing per say.

indeed test12 going great.

please please please new mali drivers :P
[Galaxy S II Original Android Development] akbarhash:
I concur. Though it would be a lie if I said I got these times magically by just installing speed mod. I spent considerable time tweaking settings and identifying culprits. Lowest brightness except maybe for 20 mins. Auto-Sync switched of when wifi off. Data off mostly except maybe for 30 mins.

Battery crapped out at 7hr 14m.

2000 mAh battery.

Gmail, Facebook, Google +, Whatsapp, Facebook messenger, Google Music syncing.

Awesome work hardcore.

Been on void echo for a couple of days and thought I'd come back to Speedmod.

Tried test 12 and it was laggy as hell, felt like it was in slow motion. Odd.

Got only 2900 in quadrant too.

K2-16 was awesome.

I had SetCPU installed but it wasn't running, I'd froze it with Titanium backup so not sure what was going on?

Yesterday i installed K18 test 12 and i found it more smoother then K18 test 7.

First result, Antutu gave 5989 and i find it a nice score.

It's running for about 10 hours now with screen on for 6 hours (watching movies with 1/3 brightness mostly) and 1/2 hour Angry Birds Rio and still have 40% battery left.

Tested Sygic for about 20 minutes and 3 times started, somehow i think Sygic is kernel sensitive, and no problems found so far.

No problems what so ever.

Using the 2000mah battery by the way and CheckROM RevoHD™ V3.1.1 rom.

[Galaxy S II Original Android Development] doongoo:
I've used other kernels before Speedmod and I've also used SetCPU. With Speedmod I've disabled SetCPU (Titanium Backup freeze), but I had to notice, that my CPU was only running on 800 MHz after a reboot (CF-Bench, AnTuTu bench). I've also got only ~2900 points in qadrant. Now I've re-enabled SetCPU with only a startup 200-1200 MHz. My CPU runs now as before and I got good results in benchmarks. If I have time, I will make a factory reset and delete SetCPU.
[Galaxy S II Original Android Development] It_ler:
You can flash the Odin tar file with Odin (application on your Windows-PC) or Mobile Odin, an Android app from the Market (developed by Chainfire).

You can find an xda thread for Mobile Odin here => http://xdaforums.com/showthread.php?t=1347899

For Mobile Odin you have to root you phone first.

Alternatively, you can use the CWM zip file to flash a new kernel with CWM Manager app (you may have to extract the zImage file out of the zip file to flash the kernel - you have to try), or just boot into CWM recovery mode, flash zip from sd card and choose the CWM zip file.

It is up to you.

Good luck !

P.S.:

If you flash SpeedMod kernel by using Odin, you will get a yellow triangle and the binary counter will be incremented (without using a Jig).

That's why I prefer flashing new kernels via Mobile Odin or CWM recovery mode.

Hello guys,

I am new on this forum.

Well, I will try to root my Galaxy S 2 and I have an doubt about this kernel.

Well, yesterday I update ( via Samsung Update Tool ) my Galaxy S 2 to Android 2.3.4, original kernel ( 2.6.35.7-I9100UHKI2-CL553601se.infra@SEI-07 #2 ).

This kernel work without problems in this version of Android ?
[Galaxy S II Original Android Development] lrcquest:
It is advisable to upgrade over to 2.3.5. But if your region doesn't give you thru Kies, pls visit intratech's post (in the sig) & choose the XWKJ3 rom (choices available). These are stock roms & you can flash the respective CSC's.

But still it you can flash this kernel for ur version as its 2.3.X gb. Quote from Hardcore's FAQ link

"Q: Which firmware versions can I use this kernel on?

A: Any stock Samsung Gingerbread firmware, and most popular customized Samsung ROMs. It does not work with CM or MIUI ROMs."

[Galaxy S II Original Android Development] ithehappy:
You need to install this kernel via CWM Recovery.
[Galaxy S II Original Android Development] myshu:
you can flash via the in-phone CWM manager app but you need to take the zImage out of the .zip file before you do that. or keep it in the .zip file and flash from recovery.

1. speedmod.odin.tar via Odin

2. speedmod.cwm.zip via CWM

I know how to flash with CWM, I've tried with CWM recovery, it doesn't work, and neither with the CWM.apk, I don't know why, but I've got the same error, the zimage can't be found... and it's not speedmod.odin, it's speedmod.cwm.

Also the .tar file can be used directly with the CWM app, no need to untar.

Results for SpeedMod 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.

I am running on Frankenstein XWKJ3 ROM and Samsung's standard 1650mAh battery.

Re-done some "older" tests and updated my comparison for the SpeedMod K2-18-test kernels:

Benchmarks

Battery stats

Test10, Test6 and Test12 had the best battery savings on my phone.

And Test10 is still the best balance between battery life and performance - for me (on my phone with my "normal" usage).

As I am preparing to flash new Frankenstein XWKK2 ROM, I will only add my results for this stock ROM to the comparison list above.

All other tests and results for the next versions of the SpeedMod kernel running on a different ROM would have other conditions, and so they were no longer comparable.

Hope that my results helped someone ...

[Galaxy S II Original Android Development] endor43:
Just to note, It seems to me that this kernel does not fix the "AOS bug" which has to do with disproportional battery drain due to misbehaving suspend and events/0. It seems that it (AOS) is just hidden in battery stats. All battery gains or otherwise do not even come close to what they should be without these processes misbehaving (which would=the bug fixed) .

I still am averaging a 3% battery loss per hour with phone sleeping, no widgets, and wifi off.

Anyone have similar results?

If AOS is indeed hidden in battery stats, I'm curious to know why, as it doesn't accomplish anything but misdirection.
[Galaxy S II Original Android Development] hardcore:
AOS and some other apps don't appear in the battery usage stats because the kernel is compiled with CPU Frequency Stats off to remove the overhead associated with the statistics logging.

In any case, it's debatable whether or not AOS appearing in battery usage is a bug.
[Galaxy S II Original Android Development] nofam:
Nothing wrong with battery life here (on K1-T16):

@Hardcore

Thanks for clearing that up man.

Hmm, now back to the age old question of GS2 battery life.....
[Galaxy S II Original Android Development] TheWizzard2203:
With the latest kernel, T17, I'm getting 10 hours and 40 minutes of total battery time. When I look at the battery usage I see that the display is consuming the most of the battery life. I have 3G/HSDPA data connection continuously on and auto sync several social networking accounts and mailboxes automatically (push mail). I have the screen brightness set to auto. This is with a few calls and a little usage of wifi and bluetooth. Is this normal?
[Galaxy S II Original Android Development] hardcore:
It seems normal, but it really depends on your GSM/3G signal coverage. The biggest user of battery is the GSM/3G radio, especially if you have pushmail turned on. If you have poor coverage, it will use more battery. If your coverage is good, it uses less.
[Galaxy S II Original Android Development] TheWizzard2203:
Okay thanks for your answer. I think the data connections has great coverage, it's fast and till now I never had any data dropouts.
[Galaxy S II Original Android Development] furrypotato:
I'm interested in knowing more about the CPU Governor , hardcore.

Many of us are used to using setcpu to overclock, underclock and undervolt anf this kernel doesnt allow that.

What's the governor like on your kernel instead ?
[Galaxy S II Original Android Development] hardcore:
This kernel uses the default governor (ondemand) with some tweaks. There should be no reason why you cannot change the CPU governor. My guess is that SetCPU assumes that cpu frequency stats is always enabled and crashes if it is not enabled (as in this kernel).
[Galaxy S II Original Android Development] cr0wnest:
10 hours is quite normal. I also have 3G and auto sync on all the time and my brightness is also set to auto. Its good that most of the battery use is on the display, it goes to show that the phone is indeed sleeping like it should be while your screen is off.
[Galaxy S II Original Android Development] monkeydrufy:
please add support to tegrak

[Galaxy S II Original Android Development] furrypotato:

[Galaxy S II Original Android Development] Krautmaster:
what about this discovery?

http://xdaforums.com/showpost.php?p=16274520&postcount=9951

Is the speedmod kernel hiding some battery stats?

I think the kernel is really fast so far, i like it, but it seems to use more energy than my older ninphetamine kernel which was undervoltable with SetCPU.

With ninphetamine i could get 0.5% / hour with 30 min sync intervals and juice defender. 100 to 93% in 15 hours.

This night with speedmod my SGS2 took around 1% / hour from 51% to 43% in 8 hours.

But its to early to made a decision because my battery needs to calibrate new after flashing.
[Galaxy S II Original Android Development] hardcore:
Android OS and some other apps don't appear in the battery usage stats because this kernel is compiled with CPU Frequency Stats disabled to remove the overhead associated with logging the statistics.
