Great results, but could you do something for me pls as you are the most experienced on testing procedures pls? Could you at your earliest convenience test exactly the same but with more realistic WiFi usage - not in one period only within testing period but with many more WiFi connections/disconnections but keeping similar screen on time? I think that difference would be significant.

Additionally the results will vary depending on the data load when WiFi is on eg battery drain would be higher if dowload/upload is higher.

So maybe to have even more objective results would be a good idea to add amount of data exchanged while wifi or mobile data is on. Sorry for bottering you with my stupid thought, I must be too tired of Christmas celebrations. :)

[Galaxy S II General] It_ler:
Yes, I think you are right.

Had the same thought myself.

So I will definitely re-do the tests on Jeboo and Siyah kernel with wifi on and running all the time.

But first I want to finish the tests with my current wifi/system settings.

Jeboo kernel v1.0e:

Nearly the same battery life in night use than SiyahKernel.

Jeboo v1.0e (XXLSJ): Battery loss of 0,69% per hour, Awake: 2,3%

Slightly better deep sleep ratio.

Now I will check its battery life in mixed usage.

P.S.:

I have "cleaned" first post now, so that there are only battery results of my current JB base ROM.

EDIT:

Here some screenshots:
[Galaxy S II General] bluefa1con:
Using siyah 6 beta 3 I lost only 2% over night over an 8 hour period

I had my wifi off if that matters
[Galaxy S II General] -iNCEPTiON-:
It really matters because Wifi is really a battery drainer on JB Leaked ROM :)

BTW i am on SiyahKernel v6.0b4 and i noticed fast battery drain when Wifi on and when i switched off the wifi , the drain was significantly less and it was really noticable!
[Galaxy S II General] It_ler:
And that is with old wifi drivers that gokhanmoral used in his kernel.

With the new/stock JB wifi drivers, the battery consumption is even higher.
[Galaxy S II General] -iNCEPTiON-:
But I have a problem ... I am having fast battey drain on siyah kernel .. previously I was over 12hours of battery life when I had 50% battery and see now.. and that was wifi ON all the time and on siyah kernel wifi is OFF and see below

[Galaxy S II General] It_ler:
Could have many different reasons, e.g. voice calls that you didn't have on your previous test run.

And I see a drop/jump down of your battery power somewhere in the middle - maybe you rebooted your phone.

These "jumps" in battery power indicate that the battery stats chip was not fully "calibrated"/settled down to show the correct battery power level.

Just retry the test on the next battery cycle to verify your test results.
[Galaxy S II General] -iNCEPTiON-:
Yes i think so , I will give it a try on the next recharge cycle.. this was a first recharge cycle though.. thats the reason i think.. :)

I will give a try and report back :)

Jeboo kernel v1.0e:

Very good battery life in mixed usage too.

Jeboo v1.0e (XXLSJ): Battery loss of 1,45% per hour, Wifi: 14,2%, Awake: 12,0%, Screen: 10,0% => loss*(1-screen): 1,31%

It has a slightly better deep sleep ratio but a little bit worse battery life compared to SiyahKernel v6.0b3 on my phone.

[Galaxy S II General] THE RED BLUR:
In version 6.0b4 he is using a different wifi driver from the previous 3 betas. I believe it's the one he ported from the Sg3.

I personally find this one drains less battery then the previous old wifi drive he used. :)

By the way I was curious to know do you have a spare sg2 you use for beta testing :D Cause I don't know how you stop yourself touching phone for like 11 to 12 hours.

I feel compared to you I'm abusing my phone and will be reported to the authority's for abusing it and not letting it rest:D

Any way as I said on NeatROM lite thread I'm leaving all further battery assessments to you.

I felt I had to step in and show siyah kernal V6 betas wasn't as bad as people were making it out to be especially the version 4 and for me who has tried all latest philz, jeboo have found it to be the best option and more convenient due to a lot of factors and most notably the conviance of the fully usable recovery.

Looking forward to you being on siyah again and hopefully your input can help GM improve the kernel more ;):):thumbup:

Thanks for the info about the changed wifi driver.

Read about it but was not sure, if it's still the same (from v6.0b3).

I don't have a spare SGS2 for my tests ... it's just my one and only smartphone ATM.

The 10-11 hours of not touching the phone is only possible during the night - when I am sleeping, my phone should sleep too :D

My battery tests can just give information about the system (kernel/ROM) running/performing on my phone with my settings.

So for the developers it is very important that more people test and report back their results/experiences IMO.

I don't have a "favorite" kernel ATM. SiyahKernel has best battery life on my phone, but there are still some little bugs - hey ... it's still a beta.

Jeboo is a nice alternative and PhilZ-cwm6 is just a rooted stock kernel with an extended CWM recovery.

Let''s wait for other custom kernels/kernel versions.

I'll keep testing them all :cool:
[Galaxy S II General] It_ler:
Jeboo kernel v1.0e:

Benchmark results added to first post.

Similar results as for stock/PhilZ-cwm6 kernel - not much difference in performance IMO.

I will re-do the battery test with wifi on and running all the time before flashing and testing the latest SiyahKernel again.
[Galaxy S II General] bobdoblo:
Yes It_ler you do a very good and hard job that is apreciated by many of us mate!

Hi It_ler I just read your op for the first time in its entirety. And very impressive and informative. :);):thumbup:

Flashed SiyahKernel v6.0b4 on my XXLSJ NeatROM Lite v4.0 some hours ago.

Everything (except the Video Player app) seems to work fine so far.

Even the touchkey light set to "Always off" work fine now.

The system feels very smooth and is very stable on my phone.

Exynos exploit is still patched - tested with Chainfire's ExynosExploitDemo app.

Hi mate. Loving this thread.

The stock video player seems to be working fine for me on latest Disaster Rom combined with siyah version 6.0b4.

I followed reds guide in installing using rom nuke. He posted his method on NeatROM thread today. :)
[Galaxy S II General] It_ler:
Yes, already saw his post.

As long as the video player works when started via Gallery, I do not feel the need to wipe/clear everything.

A simple wipe cache and Dalvik cache could not solve the Video Player issue on SiyahKernel v6.0b4 on my phone.
[Galaxy S II General] hyperthrust:
Um that's okay. But I'm starting to see a pattern here of video not working for people not doing a true wipe installation of Rom. Unless it's just isolated to NeatROM?

Hmm ... stock Video Player app on XXLSJ NeatROM Lite v4.0 works fine on SiyahKernel v6.0b4 on your phone?

What's the difference to my phone?

Here the Video Player always has FC when starting directly.

When starting indirectly via the Gallery app, it works fine too.

Have you done something special?

When I flash Jeboo kernel, Video Player app works fine. After flashing SiyahKernel (without any changes, no wipe), Video Player has FC.

As I said, wiping cache and Dalvik cache could not solve this issue for me.

Any clue?

[Galaxy S II General] It_ler:
No SetCPU but I have Voltage Control (VC) app installed (and STweaks of course).

What do you want to know?

I'm on completely default settings => CPU governor = "ondemand" and io scheduler = "row" in STweaks (in VC it shows "cfq" :confused:)

Update SiyahKernel v6.0b4:

Even better battery life in second battery cycle.

Siyah v6.0b4 (XXLSJ): Battery loss of 0,53% per hour, Awake: 2,3%

Best battery life for JB ROM on my phone so far.

EDIT:

Here some screenshots:
[Galaxy S II General] It_ler:
Haven't flashed latest PhilZ-cwm6 kernel yet, but as its difference in only CWM related, performance and battery life should be the same.

You have to decide yourself what kernel fits best to your needs.

I want a stable phone (stock, PhilZ-cwm6, Jeboo and Siyah are all stable on my phone), smoothness (all kernels for XXLSJ are very smooth IMO) and best battery life (latest Siyah has best battery life on my phone ATM).

Other aspects:

1. Brick-bug ... stock kernel is theoretically affected (but Samsung seems to have no issues in stock recovery), PhilZ-cwm6 is patched (so safer than stock kernel), Jeboo and Siyah are not affected as they both have the eMMC_CAP_ERASE flag disabled.

2. Exynos exploit ... stock and PhilZ-cwm6 kernels are affected (patching will lead to broken camera), Jeboo and Siyah are patched (on low level).

3. Extra features ...

Stock kernel has maximum compatibility for stock firmware, KIES, OTA updates, official support (warranty) but lockscreen freeze and significantly higher battery consumption for wifi (compared to GB and ICS).

PhilZ-cwm6 is rooted stock so has (nearly) the same as stock kernel, but no official support (void warranty) but root features (especially extended and patched touch CWM recovery).

Jeboo is rooted custom kernel based on HK sources so less compatibility with stock firmware, KIES, OTA updates, no official support (void warranty) but root features (especially CWM recovery, no lockscreen freeze and all current patches for safety).

Siyah is rooted custom kernel so similar to Jeboo, but with touch CWM recovery and some minor bugs (e.g. not all STweaks settings are saved after rebooting and on some phones the stock Video Player app has FCs when started directly ... but working when stated via Gallery) - it's still a beta version.

For more information read the kernel threads/changelogs.

I have just flashed siyah v6b4 again to try and sorry if this has already been asked but on stweaks I have set bln - led to 3 seconds. Do I need to tick blnww to and will these settings stick after reboot. Sorry for asking but never needed bln tweaks
[Galaxy S II General] It_ler:
I think you are asking in the wrong thread, as I have never changed those settings. I know that the blnww (BLN without wakelock) needs bln enabled too, but if these settings are saved after reboot ... Please ask in Siyah discussion thread or test it yourself.

I flashed Jeboo v1.0e and Video Player works fine.

I flash SiyahKernel v6.0b4 and Video Player has FCs.

Flashing both kernels from external sd card - Jeboo as CWM flashable zip file and Siyah as tar file with Mobile Odin app.

That could be the difference.

Will try to flahs it also as CWM flashable zip file next time.
[Galaxy S II General] jas0nuk:
It would be quite concerning if flashing from CWM/Mobile Odin/PC Odin gives different results for each. A flash is a flash.
[Galaxy S II General] It_ler:
As I don't know the cause why the Video Player app has FCs on my phone and for other users with the same kernel/ROM combination it works fine, I just want to check all possible reasons/differences.

Maybe we will be surprised when finding the real cause of that Video Player issue :eek:
[Galaxy S II General] It_ler:
Tried different sequences for flashing Jeboo > Video Player works > DorimanX > Siyah > Video Player has FCs.

Then Jeboo > Video Player works > DorimanX > Reset STweaks profile > clear init-d folder > wipe cache > wipe Dalvik cache > Siyah > Video Player has FCs.

Now I am back on SiyahKernel v6.0b4 and Video Player app has FCs when started directly, but works fine when started via Gallery app.

I can't find the solution :(

And I won't wipe data/do a factory reset, as it works fine with stock/PhilZ-cwm6 and Jeboo kernel without wipe.
