big problem for me with test 12 : wi-fi and root explorer stop working after a few days. Going back to test 8 and everything is fine, fast and smooth. I keep this one definitely, waiting for I.C.S. :-)

---------- Post added at 12:19 AM ---------- Previous post was at 12:15 AM ----------

I had also this problem with test 12 :confused:
[Galaxy S II Original Android Development] AMDPOWERFIST:
Yeh i have the same issue. Root explorer has stopped working.... wonder whats up with that...
[Galaxy S II Original Android Development] Vahidmoby:

same here :(

and i have random reboots with test 12

Checkrom RevoHD v4

for me k2-17 test 1 is Best kernel so far very smooth and battery friendly

without any problem
[Galaxy S II Original Android Development] trixnix:
Never encountered random reboots (all speedmod test). KK2 Frankentsien.

TAPATALKED
[Galaxy S II Original Android Development] zekurosu:
personally i think test 12 is a tad better compared to test 13 in terms of battery performance..

but i'll keep this until hardcore produce test 14 .... speedmod kernel for me has been the best so far
[Galaxy S II Original Android Development] Rafael1000:
Hello,

I am waiting for a final (no test) release... So I still use Kernel K2-16 (this is a good kernel but an update would be good).

When do you think there will be a new final release?

Thanks !
[Galaxy S II Original Android Development] gorillaCF:
suddenly my phone's awake status all goes down o.O no idea what happened, but clocked in 5h 10mins, and drained 15% of battery with mild usage (smses, and web browsing).

i think speedmod is great!
[Galaxy S II Original Android Development] zekurosu:
i think you should now consider custom ROM as well :D
[Galaxy S II Original Android Development] hardcore:
There are reports that updating busybox from the Market breaks things like obtaining IP from WiFi. Perhaps its a similar problem.
[Galaxy S II Original Android Development] gorillaCF:
hahaha its not even 1 week since i rooted and flashed speedmod.

not that adventurous to go into ROMs yet :p
[Galaxy S II Original Android Development] hardcore:
That's possible because test 13 has the new AFTR cpu deep idle mode disabled (test 12 has it enabled). I am trying to disable it because I think it causes the 5-second black screen problem that some people have. Not sure how much difference it makes.

Test 13 is definitely smoother than 12 though.
[Galaxy S II Original Android Development] Rafael1000:
@hardcore : Can you help me with that please?
[Galaxy S II Original Android Development] coolfire:
I definitely agree that Test 13 is definitely smoother than Test 12.

Keep up the great work, mate. Looking forward to our release. :D
[Galaxy S II Original Android Development] :

Getting good results with k2-13 in terms of stability so far -- still rock solid/no hang.

Battery loss over night was approx 1%/hour. That may not be the absolute best but pretty decent. Sync etc was active, though no screeen on time.

I know the AFTR idle mode is disabled in test 13. Was there anything else? Could any of the other tweaks to scheduler etc in any way explain why test 11,12 would just hang for me after a few hours? (stock[briefly] and test 13[since release] have not). I know I've not really run 13 for long enough -- but when hangs did occur they were all within 6 hours, on at least 3 occasions.

Interestingly I didn't have any hangs with the KJ3 firmware, they seemed to start when i switched to KK5 -- but of course I updated to latest speedmod at that time, though I'd been tracking releases within a day or two.

Any changes likely in KK5 over KJ3 that might prompt the kernel to go down different code paths and make a hang more likely perhaps? Odd...

Had crashes started I was considering going back to KJ3 - but at this point there doesn't seem a reason to. I guess next step is a test 13 change with *only* aftr change? (enabled) - though note I am not talking 5s delay, I'm talking phone goes to a mode where it appears to be running a high priority kernel thread and lags with around a 2-3 minute or more response time making any usage impossible, and seeming like a hang, just not total.
[Galaxy S II Original Android Development] BrandoHD:
Whenever it's ready!!!
[Galaxy S II Original Android Development] borrego:
With the AFTR idle mode disabled, I suppose k2-18 test 13 would be very similar to k2-17 test 1?
[Galaxy S II Original Android Development] alexkno:
test13 on stock deodexed KK5:

good battery performance (very similar to test12 but not as good as K17 for me):

currenty 3:15h display on, 30h overall on battery (8h of them on wifi, 12h on 3G) sync all time active (gmail and gtalk + facebook)

Additionally I had several boots with dalvik cache rebuild (installed different themes)

And still 35% left...very good

Only issue I had with test12 and 13 when activating flight mode two or three times it had problems to reactivate normal mode (function was grayed out and only was available after some 5-10 minutes)
[Galaxy S II Original Android Development] shawnaye:
i'm quite sure you should let the test kernel sink it abit more first, as compared to how long you did for k17 to sink in , then you SHOULD probably get bettery battery life with the test versions.
[Galaxy S II Original Android Development] HellRazorGod:
Battery life test

So I installed test 12 and went for a heavy usage period in the first cycle.

The results were out of the roof. 5 hrs of display tim[e with 11 hrs in total. Continuous usage and I played FIELDRUNNERS HD for almost 3 hours with a lot of youtube streaming Internet usage and music at auto brightness which is indicated by the peak falls. Best display on time till date. See for yourself
[Galaxy S II Original Android Development] adl:
Just had a black screen after a phone call. The phone call wasnt interrupted, just after hanging up the screen didnt went bright and no button was doing anything,even pressing the powerbutton for over 10 seconds. I waited 5 minutes and pressed powerbutton again and the phone booted up normally. Never had this before. I am on Speedmod 18 test 10 with GoaRom 1.6.
[Galaxy S II Original Android Development] alexkno:
fully right, was just first impression, and fisrt impression (on battery, not speed and smoothness) was a bit better with k17, be sure I'll keep an eye on (at least until test 14 arrives) ;)
[Galaxy S II Original Android Development] vuidoi:

nah, it's like that sometimes, screw ups in the system i guess.

mine went up 20% once.
[Galaxy S II Original Android Development] walkergeri:
what is to do, that this kernel is working with CWM manager 3?

[Galaxy S II Original Android Development] walkergeri:
yes, i know, but isnt there another solution? :)

I need to download k2-18 t12 . Please I need the download link. It's not any more located on the OP
[Galaxy S II Original Android Development] planetf1:
Had a strange situation where desktop was mostly blank (4 icons at bottom were ok), and app list was empty though I could switch between running apps.

I can't see this being a kernel issue. It's one too many "odd" thing to happen with KK5 -- seriously thinking of going back to KJ3, or perhaps KK2
[Galaxy S II Original Android Development] Dark Emotion:
You can download test12 here: LINK
[Galaxy S II Original Android Development] eseregin:
Thanks hardcore!

every new kernel better and better:-)

Appriciate your hard work on both dual core :-)
[Galaxy S II Original Android Development] marsexpress:
I had this happen to me after installing KK5, can't remember if it was before or after I put speedmod kernel on, think it was the first boot up actually. Not seen since.
[Galaxy S II Original Android Development] interfreak:
K2-18(13) is running awesomely for me, only losing about 7% battery overnight and everything is very smooth. No system stuff ups for me on XWKK5 either.

Look forward to It_ler's battery/performance tests!
[Galaxy S II Original Android Development] It_ler:
Here you can find my last results for SpeedMod kernels on XWKK5 ROM => http://xdaforums.com/showpost.php?p=20010105&postcount=5430

Now I am testing void.echo kernel for the first time.

Its benchmark results show top scores for speed performance.

(My first results are here => http://xdaforums.com/showpost.php?p=20048923&postcount=563)

It feels very smooth, similar to the best SpeedMod kernels.

Now I want to finish my tests for battery savings and will post all results as soon as testing is finished.
[Galaxy S II Original Android Development] planetf1:
After my funnies with KK5 I've gone back to KJ3 (vodafone stock official)-- and also reverted to k18-test12 (to see if there was a rom relationship)
[Galaxy S II Original Android Development] sinancetinkaya:
Hi hardcore, is there any chance to add Bluetooth PAN module into your kernel?

As far as I know bnep.ko module is missing in sgs2 as well as sgs.

I don't know why samsung is deliberately screwing its devices :mad:

Usage stats....on light usage. 3 days, 18 hours @ 26% remaining.
[Galaxy S II Original Android Development] tEsT_MaStEr:
Maybe next update would be turn on AFTR again for better battery usage.

BTW,thank for the best SGS2 kernel. :)
[Galaxy S II Original Android Development] Hilmesh:
This is what i got with Test 12. How does it look? can it be bettered. I am quite happy. did some reasonable usage in Wifi, 3G, Saw some videos & took quite a number of snaps.
[Galaxy S II Original Android Development] joezy07:
I have tried a few other kernel and this kernel is still my favourite.

the other one is Phenomenon, but since it's the derivative of this kernel, then Speedmod is still the best I think.

I really hope the next release will come with CWM 5.0 version.

:D

Your phone is awake for long periods of time without the screen being on?
[Galaxy S II Original Android Development] veeruchinnu143:
Going to update my mobile. Downloaded xwkk2 & xwkk5 firmwares. Which one is best suit for speedmod k-18 test 12(coz heard a lot abt test 12 kernel).
[Galaxy S II Original Android Development] crash_194:
I use the Rom Kitchen optimised KK5 Rom with speedmod k18 test 13, works brilliant mate. Very smooth and very snappy (more so than test 12) and also good battery life.
[Galaxy S II Original Android Development] veeruchinnu143:
Yeah but I think I downloaded the xwkk5 stock rom(From original android development form). What's the diff between Rom Kitchen optimised KK5 Rom and actual KK5 rom...?
[Galaxy S II Original Android Development] It_ler:
Stock ROM is (nearly) identical with the officially released ROM of Samsung.

Kitchen ROM is something different, it is a custom ROM and comparable with a workbench where you combine different parts to build an individual, optimized solution.

Have a look here => http://xdaforums.com/showthread.php?t=1133846&highlight=Kitchen+ROM

Read and decide, if this is where you want to go.

Good luck !
[Galaxy S II Original Android Development] Hilmesh:
I do not understand what you mean by awake. But my phone has been ON for the full 2 Days and 14 odd hours. The screen not necessarily for the whole period. The screen for maybe 4 Hrs.
[Galaxy S II Original Android Development] It_ler:
Awake means not in Deep sleep.

So, this is the time in which the CPU is not idle.

You can check it better by using CPU Spy app from the Market.
[Galaxy S II Original Android Development] ballmead:
If you look at the second picture you posted the CPU is awake (processing away for long periods of time) while the screen is off).

This would eat the battery pretty quickly.

As suggested above, CPU spy or BetterBatteryStats Apps can show you why this is happening.
[Galaxy S II Original Android Development] Hilmesh:
So basically what you are trying to say is if the situation improves then I can get more battery backup?
[Galaxy S II Original Android Development] Hilmesh:
I have downloaded it. How should I use it. please advise
[Galaxy S II Original Android Development] mathsmart:
so basically the best kernel ''battery saving'' is test 12 with a bit less smoother than test 13 right ?

I tryied siyah 2.4 and the battery drain so fast ! so I get back to speedmod test 12 to see ! somesaid test 13 is great on battery life also but a bit less than test 12 right ?
[Galaxy S II Original Android Development] Chanz09:
Here is my test results for test 13. I got same or better results than test 12 posted earlier. The only difference is the new rom. 2kmah battery
[Galaxy S II Original Android Development] planetf1:
Quick update - back on KJ3 + test12 & working very well - no hangs so far & excellent battery life.

My earlier complaints with test12 were with KK5 -- and over a few days using that ROM I found a number of things that just didn't seem quite right. Maybe that was somewhat anomolous .
[Galaxy S II Original Android Development] anisbombaywala:
Wow!!

Results for SpeedMod / void / 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

So for me (on my phone and with my "normal" usage), void.echo kernel is very fast and smooth, but its battery savings are not as good as of the best SpeedMod kernels.

One aspect I never considered before, as I only used stock and SpeedMod kernels, is the system stability.

With void.echo I had several issues that I never had before - neither running on stock nor on SpeedMod kernels.

As I have not examined the causes of the (*) and (**) issues, I cannot blame void.echo. I just observed these issues. Maybe they result from a combination of software (kernel, ROM, apps), hardware (my phone) and usage (my personal usage) ?!

I can only conclude for myself that void.echo is not the best balanced kernel for me (my phone and my "normal" usage).

P.S.:

As long as hardcore does not release a new version, I will flash SpeedMod K2-18-test12 again. It seems to be best for battery life (at least in the night and during minimum usage) on my phone.

Maybe it will change as soon as I flash XXKL1 ROM to my phone.
[Galaxy S II Original Android Development] planetf1:
a good decision to go back to kj3 and test 12.

15 hours on, with sync, plume etc active. Only 1.5 hours display time, but battery still at 50%, though this is in good signal, data via wifi, and stationary
[Galaxy S II Original Android Development] ballmead:
Yes, if you can work out what is causing your CPU to be awake when the screen is off, you will reduce your battery consumption .

---------- Post added at 09:13 AM ---------- Previous post was at 09:10 AM ----------

CPU Spy or BetterBatteryStats?

CPU Spy will show you what state your phone is in.

BetterBatteryStats goes into it in far more detail, have a play and try it out for yourself.

It should be in Deep sleep most of the time that you are not using the phone and the screen is off.

Things that like to auto update like Facebook, Gmail, Google account sync, Gtalk, Samsung account sync etc wake the phone up when in deep sleep.

If you want to improve battery you can do some of these things manually.

Some other Apps prevent the phone from deep sleep, as you have long periods of time where your phone is awake when the screen is off, I would use BetterBatteryStats to see which App is doing it.
[Galaxy S II Original Android Development] dzontra11:
Guys..what you think about this screen shot and battery life..good or.....???

Tnx
[Galaxy S II Original Android Development] ballmead:

Is your cpu oder your gpu overclocked?

I have a deodexed and handoptimised system build from WanamLites package (removed all garbage from /system/app) and SpeedMod Kernel K18-test12.

My vallemo benchmark result ist ~1050 and better than other I found for non overclocked.
[Galaxy S II Original Android Development] Hilmesh:
I will check it out as you suggest. But 2 days and 14 hrs is good I think. What do you say?
[Galaxy S II Original Android Development] It_ler:
No overclocking at all.

I recognized the "boost" in Vellamo (browser) benchmark after switching from XWKJ3 to XWKK2, and another slight one from XWKK2 to XWKK5. It seems to be ROM related, but curious.

That's why I have added the Vellamo test results to my list.

Here are my complete Vellamo results:

Boot Animation

Hello guys.. I read to other thread that there is a guide on how to put Boot Animation on SpeedMod Kernel. After 1hr of browsing this thread, I cant seem to find the guide.. Can somebody help me or give the link for the guide?

Thanks so much..
[Galaxy S II Original Android Development] rodak:
What's up with the bootanimation love? I just can't get it. Are people restarting their phones all the time to see some stupid animation for a couple of seconds?
[Galaxy S II Original Android Development] billab0n6:
After 1hr of browsing? I guess u missed the first post from Hardcore
[Galaxy S II Original Android Development] AMDPOWERFIST:
OMG i totally agree....

its 5-8 seconds of time.... when your phone restarts....

how often are people restarting their phones to actually care about the boot animation...

do you walk around the street constantly restarting your phone and showing random people what it looks like... or showing friends the boot animation ? just look them up on youtube, and show your friends from there, saves you actually rebooting the phone LOL

such a trivial thing.... same with the yellow triangle at boot.... who cares if its there either? unless your sending your phone back for warrenty or insurance purposes, does it really matter if it appears ???
[Galaxy S II Original Android Development] alexkno:
C'mon , it's up to anybody to choose a boot anim or not....
[Galaxy S II Original Android Development] AMDPOWERFIST:
oh i totally agree...

each person should have the rights to have their phone the way they like it. I'm not suggesting they shouldn't, im just saying, does it REALLY matter that much? would people not prefer speed and simplicity and battery life over a 5-7 second boot animation they see probably once a week give or take ?
[Galaxy S II Original Android Development] interfreak:
No it doesn't 'REALLY' matter that much, but the poor guy was only asking a simple question.

Say in your case, Why install the Sony Bravia engine? Do you walk around the street constantly showing random people what it looks like... or showing friends? just look it up on youtube, and show your friends from there, saves you actually installing it on your phone LOL

such a trivial thing....

Android is all about customisation, don't knock someone just because they want to customise their phone...that's why they are on XDA.
[Galaxy S II Original Android Development] BrandoHD:
The real question is why the user had to browse for 1 Hour when I was able to find the exact post in less than 3 minutes.

Is it a good idea to post the info seeing as the method to change boot animation is a lot more complex than finding the info in the first place???
