You should try on your own. But start with NEAK and lulzactive. Read OP and you'll see my settings.

Hey Bajee,

Have you upgraded to 27.04 already, I'd like to get some descent feedback first before flashing the update. Para's thread is flooded I can't understand if it's good to update. :(
[Galaxy S II General] XDA mark:
I believe since 14/04 most Hydrogen ROMs are about the same battery wise. Most changes are features wise. I'm not sure though, I'm still on 14/04 and it's good :p

---------- Post added at 03:52 PM ---------- Previous post was at 03:43 PM ----------

"just tell me which is best for battery"? Lol that sounded a little bit rude but lets move on :P

I'm not on CM9 but on a CM9 based ROM (Hydrogen, AOKP). I am using Siyah v3.1RC6 still, fantastic batterylife. I use VR + Lulzactive and I tweaked the Lulzactive govener with Tegrak's Lulzactive app from the Play Store.

Performance wise you deliver but battery wise you gain.
[Galaxy S II General] bajee11:
Doing it as we speak, and I might actually keep the new Standard.:rolleyes:
[Galaxy S II General] clifffhanger:
I have installed mine but used NetChip 18.04 as the new one doesn't have lulzactive in it
[Galaxy S II General] bajee11:
I installed N.E.A.K 2.0.3x, going to start testing this combo. :)
[Galaxy S II General] clifffhanger:
I just got back to NetChip bundled with the 27.04 update. Wifi doesn't work on 18.04 kernel. Sad but conservative + VR is working good on 27.04 except some heating issues that I UV can't seem to handle. :( If I can't handle this, I might go back to 18.04 until a much stable update from Para.

SiyahKernel v3.2b4

Posted on April 30, 2012

Changelog:

new feature:

breathing effect

for native bln implementation. to enable: “echo 1 > /sys/class/misc/notification/breathing” it will only work when bln notification is active.

set touchscreen threshold settings to cm9 settings.

bln options configurable in ExTweaks app. we have enable/disable BLN checkbox, notification timeout, breathing on/off, led timeout (for cm9 or some AOSP roms which do not have led timeout settings) and testing BLN button.

make sure that you do not have blinking enabled if you want to use breathing effect in BLN. also, use only one notification timeout setting, either in ExTweaks or BLNPro app.

Looks interesting.. :rolleyes:
[Galaxy S II General] Badassian:
Hi bajee, thanks for the awesome tests, it helped a lot.

However i still get the android OS bug eating my battery up like there's no tomorrow, and I notice you don't. I have exactly the same setup as you with Siyah 3.1.2 and I'm wondering if you have any idea what reason causes this bug other than the software/developer bug reason.
[Galaxy S II General] bajee11:
Using Hydrog3n? If you are, I read someone posting something for that issue. Here try this:

Turn on Airplane mode

Turn Off phone

Wait 1min

Turn On phone

Turn off Airplane mode

Another solution would be to do a clean installation. (Wipe everything and only put back what you need)
[Galaxy S II General] clifffhanger:
It could also be due to your soft keys left lighten up for so long. Try checking wakelocks using BBS to identify the culprit.
[Galaxy S II General] Hk.Tang:
bajee should try dorimanx kernel :cool:

---------- Post added at 10:57 PM ---------- Previous post was at 10:55 PM ----------

Sound good :) mind to share ur currently lulzactive settings ?
[Galaxy S II General] bajee11:
I'll add that one to my list as well :D
[Galaxy S II General] landerson07:
What settings are you using in lulzactive?
[Galaxy S II General] bajee11:
I believe he's using these:

inc_cpu_load = 80

pump_up_step = 3

pump_down_step = 1

up_sample_time= 28000

down_sample_time= 40000

screen_off_min_step= 200MHz

HyDrOG3N-ICS 27.04 + N.E.A.K 2.0.3x Test Results are up on OP. :)
[Galaxy S II General] landerson07:
I've set these now! Are these settings geared for battery or performance? Or is it a good balance?

Cheers
[Galaxy S II General] Hk.Tang:
how bout the extweak profile ? Battery or default
[Galaxy S II General] bajee11:
Battery profile and tweak GPU voltage
[Galaxy S II General] bajee11:

[Galaxy S II General] JPHCCFC:
Bajee what's your daily driver kernel when your not testing?
[Galaxy S II General] bajee11:
Been testing too much that I don't even have one.:rolleyes: I'm debating between Siyah and NEAK.
[Galaxy S II General] awaisuk:
Will just setting the lulz setting without undervolting save me battery and give good screen time?
[Galaxy S II General] shadowblade330:
did u have any bugs when u updated to 2704, I had one for the NEAK kernel not working properly with lulzactive, but I did not do a clean wipe so maybe that could be the problem.
[Galaxy S II General] bajee11:
It will depending on your usage. But lulzactive itself as a governor with these tweaked settings will save you more battery. UV is not necessary, it will only give you a little extra juice, not a 'major' difference maker.

Nop no bug at all. I always use kernel cleaning script. Only time I had issue, was today when I used the script and flashed Thoravukk 2.50, my WiFi wouldn't work. But finally figured out it was my modules that were erased by cleaning script and weren't back with the kernel. Had to copy modules from /lib/modules/ and paste them in /system/lib/modules/
[Galaxy S II General] :
awesome results :)
[Galaxy S II General] Hk.Tang:
Ok , bajee .. if i using latest siyah wanna flash b rc6 , what's should i do ? reset extweak profile thn can le ?:confused:

Or flash samsung ultimate kernel cleaning script ?

N

lulzactive / VR the default ondemand suspend freq was ? 500mHz ?
[Galaxy S II General] superleeds27:
Netchips kernel is probably the best ive tried!

[Galaxy S II General] bajee11:
Flash siyah rc6 and reset profiles. And then reboot into recovery and choose battery or performance. No need for cleaning script. Yes, default is 500 but only works with On Demand governor, It wouldn't work with lulzactive governor.
[Galaxy S II General] Hk.Tang:
Mean i using lulzactive governor .. tat ondemand suspand freq just let it 500mHz thr ?
[Galaxy S II General] awaisuk:
Hey,

I used your uv and gpu uv settings and also lulz settings with n.e.a.k 2.0.3 and I lost 11% during the night with no usage, no sync or updates, but data on all the time. Is that normal?
[Galaxy S II General] bluedragon38:
I think i have a problem , i flash the 27.04 Hydrogen .. and want to try your netchip config bajee .. but i don't have the lulzactive governor ... WTF ?
[Galaxy S II General] bajee11:
It only applies if you're using On Demand governor. So just leave it like that, it won't change anything.

That's not normal. Do you have BBS(batterybetterstats)? if not, you should get it and we could try to see what drained your battery. I usually lose 2-3% overnight with WiFi ON and Autosync ON.

It's not a problem. 27.04 Stock kernel does not have Lulzactive.
[Galaxy S II General] awaisuk:
Ok thanks where exactly do I look in the betterbattery stats to see what is eating battery? There are a few settings in that app, but not really sure where to look....
[Galaxy S II General] bajee11:
Look mainly for Partial Wakelock, Kernel Wakelock, Process.. It will tell you what keeps the phone awake instead of deepsleep.
[Galaxy S II General] clifffhanger:
If the culprit is "vbus_present" on kernel lock, do the airplane mode method posted on page 27 of this thread and it should fix the issue. :)
[Galaxy S II General] yabadabadooo:
Don't know, I'm on 2000mah battery using your stats on Netchip kernel but I got crappy battery life. Losing 5% in 20mins screen on time.

CPU spy seems to be ok.

Better battery stats i cant analyze..

Maybe someone could have a look. Would be nice
[Galaxy S II General] clifffhanger:
Weird, you have ""deleted_wake_locks" (): 1 h 48 m 16 s (6496 s) Cntc/wc/ec)148654/0/4698 5,5%" Have you tried the steps on page 27 with the airplane mode method?

Last resort: re-install the ROM:(
[Galaxy S II General] bajee11:
"deleted_wake_locks" (): 1 h 48 m 16 s (6496 s) Cntc/wc/ec)148654/0/4698 5,5%

NetworkLocationLocator (Google-Dienste): 26 m 25 s (1585 s) Count:399 2,9%

com.google.android.location (): Wakeups: 411

These would be your main issues for now I believe. What do you use that requires Network Location, because seems like it has quite a lot of wakeups:411. Try to turn off Network location and make sure no apps is trying to ask for location by disabling it in their settings. If you're getting better battery after these changes... you found your problem. Let me know how it goes.

** Use the "Hold Back to Kill" function available in Rom Control>General UI>Hold Back To Kill. It is very useful to close an app.
[Galaxy S II General] awaisuk:
Here are my stats as well:

My battery is at 10% now and in total I only got like 2hr 15mins screen time. I have UV, GPU UV, and lulz same as your setting. Also no BLN.

I am using N.E.A.K 2.0.3
[Galaxy S II General] T3rran:
N.E.A.K. battery

Hi guys, I'm back for a bit to share with you my battery usage on the HYDROG3N ROM (14/04) with N.E.A.K. kernel version 2.0.2x. I didnt do any extensive testing, I just used the phone as I normally would. I like my battery to last long, I didnt use any data, very occasional wifi connectivity with some browsing, some phone calls, sms, but no games or other prolonged heavy activities :) The governor is set to lulzactive, lowest step is 100Mhz, battery is standard stock. In case you wondered, the weird steep falloff in the battery graph is a strange thing that happened to me one morning after I turned off the alarm and couldnt unlock the phone anymore, had to reboot and after the reboot, the battery % really fell down. Maybe its stupid to upload corrupt stats, but still, after the battery glitch, I managed to get a good 2 days on light usage on stock battery.

So far I have to say that N.E.A.K. is really the best kernel for me regarding battery life. For the moment I've switched to Resurrection Remix (1.7), just to check what's changed but it seems to be really on par with the 14/04 version of HYDROG3N ROM when it comes to features/stability/etc... I've tried Thoravukk on the Remix ROM but my gs2 seemed to be suffering from some sort of kernel wakelock issues which I didnt bother to investigate. so now Im on 2.0.3x and the better usage really improved just as I thought it would. Especially during deep sleep.

Im gonna do some more tests of HYDROG3N ROM again after the new version is built/uploaded. Since I can't post in Development forums yet (such a bummer:(), I'd just like to express my thanks this way to Paradoxxx, Netchip and other contributors for doing a hell of a good job on the ROM, and CONGRATULATIONS for becoming the 1st official AOKP developers for SGS2!! :)

RILJ (Phone): 23 m 43 s (1423 s) Count:770 15.8%

AudioOut_1 (1013): 21 m 3 s (1263 s) Count:143 14.0%

RILJ:

"Dialer RILJ is the userland counterpart of the RIL (radio interface lib). RILJ handles whatever the phone need to tell or get from the RIL = phone, e.g. dialing but also coarse location." There's probably a logical explanation why this took 23 m 43 s, but I'm positive it's due to poor signal.

AudioOut_1:

Disable Touch Sounds, Screen Lock Sound in System Settings>Sound

My phone is on silent all the time. No vibration either. Also I have very good signal....so I am not really sure whats wrong .....

[Galaxy S II General] AsherChua:
Anyone has similar problems like me? What's with this kworker?
[Galaxy S II General] clifffhanger:
Dude, looking closely you still have 91% battery so it would be hard to determine. Also, items below kworker are system apps which should be fine. You should see their just running for about 6 seconds.

Take a look at kernel wakelocks or partial wakelocks instead if you're having issues with battery drain. :)
[Galaxy S II General] AsherChua:
Yeah I know, just charged it! Seems like it was because of Siyah. Flashed back to stock kernel and everything seems fine now!:D

Any cleaning script is fine as long as you know what each one do. But yes, ultimate kernel cleaning would be fine.
[Galaxy S II General] clifffhanger:
flash ultimate cleaning kernel then flash siyah again, reboot on recovery, select battery setup, clear cache and dalvik, reboot system and observe. Seeing your results, it seems you have kernel wakelocks that might be the cause of the issue. :)

Help with lulzactive

Hello guys,

i'm using last Hydrog3n (04.05) + N.E.A.K. ...

right now with lulzactive but i have a problem...

the cpu never goes below 500 MHz...

pump up step is 1

if i set it @ 2 it goes stable @ 800 and never goes down. :confused:

if i put on ondemand it goes @ 200 and works normally ... i'm very confused because it's the first time this happen with neak.

btw first time on hydrog3n

help!

when i'll get this right i'll post my results ...
[Galaxy S II General] AdrianS2K:
Please help me!

Where can i download the kernel (flashable zip), which came with the latest (04/05) Hydrg3n-ICS rom? If it is possible, i don't want to reflash the whole rom, because of the kernel.

Sorry for my english! :o

Thanks!;)

[Galaxy S II General] bajee11:
This is very unusual..I don't think this is a rom problem since on demand works okay for you. What is your pump down step? Did you do a full wipe before coming to HyDrOG3N? If not, I strongly suggest you do that. Try to post on N.E.A.K thread as well to see if others have reported the same issue.
[Galaxy S II General] AdrianS2K:
Thank you very much both of you! ;)
[Galaxy S II General] GoldGanja:
bajee first of all thx for the support, i can't post on neak kernel thread because i don't have the rights to do so (less then 10 msgs) ...

i have done the full wipe before the installation, format sys data and cache + dalvik!

my pump down step is 2, but even if i bring it to 1 nothing happen...

from CPU SPY, after 4h i got: 3h 32m of deep sleep, 22 min @ 200MhZ and 7m @500 ... the rest is scattered in other frequencies. display on 20m.

maybe I'm worried unnecessarily, but usually when I opened the Neak configurator without touching anything else, the CPU remained at 200 but now stays at 500.

I tried all the rom / configurations possible but it seems to me that no consumption is comparable with CheckROM v6 + Neak that I used before... :(

i'll give an update tomorrow morning ... thx! ;)

P.S. Btw this Hydrog3n is the first AOKP rom with a decent scroll that i try! Amazing!

P.P.S Omg there is already a newer version! :eek:
[Galaxy S II General] clifffhanger:
Pump up depends on the demand. Most probably something is running that needs to use a higher frequency. :)
[Galaxy S II General] shadowblade330:
I am having a deep sleep problem I noticed it on Siyah Kernel 3.2b5 and b7 wonder what is causing this?

[Galaxy S II General] kurtcl21:
Hey bajee11 n' guys, I'm a noob, then I wanted to ask an couple of questions.

I am currently testing the hydrogen rom (kernel abyss 1.6b governor abbysplug), and I've been reading that to optimize battery performance in a rom in general I have to play the following parameters:

1 - Kernel

2 - Governor

3 - CPU and GPU Voltages

4 - Scheduler

5 - Tweaks

6 - Scripts

My questions are:

a) can change the settings of the governors? (I know lulzactive have an application in the market that allows it)

b1) The voltages are changed in CONTROL ROM right? Are the voltages that appear to me to edit depends on the kernel?

b2) Are there any "standard" voltages settings? (extreme, normal, light, etc)

c) What is Scheduler?

d) What are the tweaks? are configurations of the governors?

e) What are the kernel's scripts?

f) Are there any other parameter (kernel) that can be modified to optimize the use of battery?

I would greatly appreciate your answers
[Galaxy S II General] msquared:
How does this kernel work on cyano 9??
[Galaxy S II General] bajee11:
a)Yes you could change the settings of the governors with script. But my daily governor is lulzactive and I use lulzactive app to change settings.

b1)Yes you could change the voltage through Rom Control>Performance>Voltage Control. The voltage that appears already, are the ones set by the kernel upon flashing it.

b2) There isn't any standard voltages, because it all depends on the user and the users phone. One sets of voltage would work for one but not for another person. You have to try to find out what's the lowest UV you could apply to your phone by testing it. But the ones you already have without modifications, should always be stable.

c) (I/O) Input/output scheduling basically describes the method that the OS decides the order of the I/O operations that should be submitted to storage.

d)Tweaks, is just a term used when you modify governor, cpu, gpu settings.. You "tweak" the settings.

e)It's any script placed in /system/ect/init.d/ that will modify parameters of the kernel, such as governor settings, gpu voltage, cpu voltage, cpu frequency table, gpu frequency, bln settings if supported and much more.. Some people prefer to use apps to change those settings but some prefer scripts because it gets applied at the very beginning stage of boot. First the bootloader loads, second the kernel drivers and finally init.d scripts run. By using scripts, you don't have to use any apps to change kernel settings.

f) There's always different parameters you could change such as cpu and gpu threshold, AFTR+LPA enabled, hotplug enabled and you could also enable sched_mc, but I find it is not effective if Hotplug is enabled.

This is a kernel testing thread only. I test different kernels with my rom and post up the results so users could have some kind of reference of the pros and cons. There's no kernel to download here, sorry.
[Galaxy S II General] bajee11:
Currently testing Abyss 1.6b and I gotta say, I'm pretty surprised by the performance and battery life. This might be a keeper for me.
[Galaxy S II General] kurtcl21:
thank you so much, u are so friendly ;)

Only for this time, when you finished (or in the meantime) can u explain how to do the configurations with the hydrogen rom and abyss kernel? please... because i don't know if you use scripts or programs and how to do it!!!
[Galaxy S II General] bajee11:
I basically went into Abyss settings in recovery mode before the test:

Enabled AFTR+LPA

Enabled Hotplug

Disabled sched_mc

Disabled BLN

Installed Abyss script

Reboot

Then I went to system/etc/init.d/ with ES File Explorer and modified S90abyss script file as follows:

GPU Clock:

GPU_STEP_LOW=100

GPU_STEP_MIDDLE=160

GPU_STEP HIGH=267

GPU Voltage:

GPU_VOLT_LOW=850000

GPU_VOLT_MIDDLE=900000

GPU_VOLT_HIGH=950000

I ran the script with Script Manager since I didn't want to reboot. You could also reboot, and the script will get applied, just make sure you set the right permissions and enable Rom Control>Start-up Tweaks>Enable start-up tweaks

For the rest, I used Lulzactive app (my current settings are posted on OP) and undervolted cpu with Voltage Control Extreme. (I could of done these with the script as well, but I always use these app anyways, that's why I didn't modify anything concerning CPU in the abyss script file.) Hope this helps, good luck.
