I´m using BLN control Pro 0.14.6 Beta a long time - working fine, but know no LED....

Today I reinstalled (uninstall and new install) BLN control Pro - dito liblight

Test with BLN control Pro is also not working....

Edit: its running now - ProfiMail and Option "Show notification" (must be disabled! Bug in ProfiMail) is blocking BLN. Thx for testing - chadouming.

@ gokhanmoral and to other devs

Beta 6 is giving me exceptional battery life, the previous betas had partial wakeups but this beta6 has no problem like that, i can clearly see it from the battery usage tab and betterbatterystats to confirm it. May i know is there any new technique implemented in beta6 for battery life and if so will those be implemented in the final release?

Had some strange behaviour on beta 5.1. Phone was running fine all day. Suddenly while on xda , I started getting lag. Phone rebooted. When I got it back up checked my lost.dir folder and it was full.

I had to reflash my Rom. Don't know why this would happen suddenly. I was on stock settings.
[Galaxy S II Original Android Development] cmd512:
100% agree with this, I thought my eyes were deceiving me when I suddenly noticed there were very few wakelocks in betterbatterystats as compared to before. Good to know others are seeing this as well, way to go gokhan. :-)

I have the same issue on b6.

Any idea?
[Galaxy S II Original Android Development] Rockin_Zombie:
reporting the awesome battery life in b6, I took tons of videos and pictures, played games, call, text, almost 3 hours screen time, still 35% left, that too with overclocking to 1.4 ghz! watever you did, don't change back:P

basically in this version of CWM "install zip from sdcard" means external sd, and you have separate option for internal sd.
[Galaxy S II Original Android Development] g2tl:
right, and that's what I'm trying to achieve. It's just that the external sd won't mount.

Last night my batterie drains from about 30% to 0 while Mediaserver was the highest within 45% of battery. I'm using 2.2beta6, played a little, 1 call, some xda threads. Not really intensive use. With the 2.2beta5.1 i had 1% drain over night. But last, it turned off, so i overslept today :/

Does anyone has the same problem? Is it because of beta6?

PS: I'n not the only one. Some user on android-hilfe.de have the same problem, there is also mediaserver the one who kills the battery

with beta6? and there is no drain from mediaserver?
[Galaxy S II Original Android Development] jooops:
Personaly i think version 2.1 is still the best evah made. Im getting drains with 2.2. So im back on 2.1 with the gingermod rom and no frills and cpu voltage. Cpu schedular is ondemand and i/o schedular is noop. The phone can last for max 2 days. With normal student usage. Calling, facebook, mailing, etc. Best combination! Tried all kernels: speedmod, jefrey, ninphetamine, ragemod, ICS infratech kernel, some other small ones.. SIYAH definitly the best. Also gingermod the best so far. Tried exynos rom ( stopped since he started to aks for more money the second time with another lie) checkrom, revolution rom, cognition, miui (which likes battery juice) and lightning rom.

So thats my deal. And im to happy that finally after an half year past by i got a phone which is stable, fast, more open than iphone and still with a good battery. Gokhan THANKS!!!

ΙΜΗΟ hotplug is the only and the right way to go, for the best battery/performance ratio. Completely turning off one core or continuously using both, are extreme case scenarios and I can't find any real practical use for it. After all what we are all looking for is the best battery/performance ratio.

But if someone makes the up and down threshold of second core activation user adjustable through init.d, with the option to set different values during screen on/off...

well that's something really really interesting to do and I think it really worths the effort :)

[Galaxy S II Original Android Development] tolis626:
@Gohkanmoral or anyone who can give a proper ****

So,the other day I posted about Smartbench not completing the test when I force dual-core mode with 2nd Core app.Now,this might be interesting.Some Linpack results first:

1200MHz

Single thread test : about 50-55MFLOPS

Mutli-thread test: 90-95MFLOPS(occassionally just below 100)

(So,multi-threded testing gives about twice as many MFLOPS)

1624MHz(That's what I'm using,so get over it :D )

Single thread test: about 75MFLOPS(Much more consistent here)

Multi-thread test: 115-125MFLOPS

Notice that in the 1624MHz test,in multi-threaded testing it doesn't even give anything near to double?It's more like cpu0(First core) is running at the user-specified 1624MHz and cpu1(Second core) is still running at 1200MHz.So,either something is wrong here,or I'm too much of a "1+1=2" kind of guy. :p

I'm no benchmark addict,but I trust Linpack. ;)

Now,if you could look into thing Gok,I'd be grateful.If not,is there any way for me to turn off cpu0 and use cpu1 in single-core mode or something?
[Galaxy S II Original Android Development] cmd512:
Here we go, comparing battery life again when idling... and in airplane mode for that matter. Your battery drained out overnight? Better question is... Why are you not charging your phone overnight???

I wonder if some of you even need smartphones given the silly tests you're running...
[Galaxy S II Original Android Development] droidphile:
I might be telling utter non-sense, but may be in a script, in an infinite while loop:

(to turn only cpu1 on)

echo "0" >sys/devices/system/cpu/cpu0/online

echo "1" >sys/devices/system/cpu/cpu1/online

(After all, in deep-sleep both cores are shutdown, so cpu0 can be turned off :) )
[Galaxy S II Original Android Development] KcDaRookie:
@cmd512: This has nothing to do with testing or whatever, but if my phone is fully loaded to 100% why whould I still let it plugged to the charger? O.o

This is more silly than having your phone idling over night and seeing that it only lost 1% in the morning...
[Galaxy S II Original Android Development] Alienfreak:
So you wanna tell us that just because threre is a fancy 100% on your screen you risk letting it alone for 8 hours while maybe some freaking Game is going rogue and thinks it can wake it up all the time and pump it up to 1200MHz, leaving you with a drained phone in the morning and probably no means of recharging during the day?

This sounds definatly more "awesome" then just letting it cycle over night while being connected to a charger and leaving you with a freshly 100% charged phone in the morning?

[Galaxy S II Original Android Development] Alienfreak:

[Galaxy S II Original Android Development] tolis626:
Well,cpu0 CAN be turned off in general,but I don't know if it can be turned off instead of cpu1.

Secondly,I already tried these scripts you said,but they change nothing,not in dynamic hotplug mode nor in single or dual-core mode.

Thanks by the way! ;)
[Galaxy S II Original Android Development] lpsi2000:
Let me try to see if I can shed some light on this. First thing to keep in mind that dual core does not equal dual CPUs. I don't think due other things that are going on with the phone that you will get both cores to run at their max simultaneously in parallel to each other. The cores are supposed to multitask on the work stream and if you got both core to lock at their max potential, I think the phone will freeze.

Multithreading behavior is little bit different. It all depends on the application, number of threads, number of tasks, and which core is handling which thread, etc... As you can see this thing can get hairy very quickly and to understand it better you will also need break down the algorithm being implemented by each of the items I have listed above.

All I am saying with my post here that 1+1 may not equal 2 in this case. There may still be an issue but I don't think you will ever get 1+1 to equal 2 here. And I think you already prove that with your first run.
[Galaxy S II Original Android Development] tolis626:
Well,I do know that it's not the 1+1=2 case here.Yes,the first run proves it,but it's much closer to 2 than the second run.What I want to see is whether there is a "problem"(If it can be called a problem) with the second core's overclocking.Based on what I've observed,the multi-threaded test should give about 140MFLOPS.Nothing too much to worry over but still... ;)
[Galaxy S II Original Android Development] fasst:
Let me ask you. If we at all are going to measure anything, what would your suggestion be of a uniform state on the phone that would give us a comparison base so that it is possible to compare at all?

We have all seen the hundreds of postings stating 'I have very good battery life, 5 hours screen time, playing for 2 hours, 15 SMSes', and more this and that.

Then all the questions from others after: What govenor are you using? UV, OC or what? And maybe: do you have the stock battery, 2000mAh or more?

To compare anything with so many variables are useless.

I've been measuring, for myself, the mA draw, in deep sleep with the same state on Wifi, data off etc., over hours at night, with different betas and different governors, and I have seen quite big variations in mA draw. I regret now that I wasn't a bit more systematic from the start and made some type of chart of what I have experienced. It could be useful for myself, and maybe others.

But if you have any suggestions to measuring methods of anything, battery life, speed etc., that could be some sort of uniform and comparable, I would gladly try them out.

Only then we can have anything to compare against, and maybe conclude what's working better than others. I beleive many are interested conclustions, not only wild guesses.
[Galaxy S II Original Android Development] lpsi2000:
LOL, I hear you. You are looking for that perfection:D
[Galaxy S II Original Android Development] droidphile:
A possibility could be that, since cpu1 active threshold is 70 %, at 1624 mhz, it takes longer time to reach 70 % as compared to 1200 mhz. Hence at 1624, single core is active for longer time as compared to 1200.

This relative-lower-time spend on dual cores could be the reason why 1+1!=2 for 1624.

EDIT: Just noticed you were not using dhpm for the test, but dual core mode using 2nd core app! My bad..

Hi, I found a bug or a problem don't know but here it is...

I am on beta6, 100-1200mhz, conservative, dynamic hotplug mode. I am using Wanamlite KI8 ROM 4.5.

The phone goes to deep sleep when WIFI is on and screen is off.

But, I it does not go to deep sleep rather remains on 100-200mhz while Mobile Data is On and screen is off.

Even it remains on 100Mhz while charging, I don't know if that is normal.

I don't know it the problem with ROM or Kernel.

Please look into it and any help wud be appreciated.

[Galaxy S II Original Android Development] kwerdenker:
As lpsi2000 already hinted at, dual-core doesn't exactly mean dual-cpu (ok, that statement is also false, depending on what naming convention you want to apply but it serves well enough for this explanation ;) ). Both cores still have to share most of the resources (memory and i/o access for instance), thus there are many possibilites for bottlenecks if the two of them try to run at full speed. This is all dependend of the architecture of the cores and the SoC but in general you can't assume a linear scaling of performance by adding another core to the mix. Somewhere there is always some overhead to consider^^

If you didn't use an external amperemeter to measure the draw but relied on some piece of software for this, your measurements are useless. Software has to wakeup the cpu to do their work, thus negating the deep-sleep of the device.

I also think it's impossible to generate any kind of useful batterystats that will be consistent across the board because of too many variables involved. Why don't we all start enjoying our mobiles and all the joy they can bring us and stop worrying about battery life (which for me isn't that much worse than on my old hero btw. and consindering I'm using my phone much more now this is really good ;) )?

BTW: This discussion would be very well suited for the q&a thread... *hint*hint* ;)
[Galaxy S II Original Android Development] xavihernandez:
I'll start using hotplug when ICS comes I think since gingerbread does not handle multicore well.

Don't know about mobile data mine does act like you.

When charging phone does not go into deep sleep because it does not need it.
[Galaxy S II Original Android Development] WebReaper21:
The phone being on 100 MHz while charging is normal behavior.

But I don't think that it should stay awake on mobile data connections. Have you looked for wakelocks with betterbatterystats from the market?
[Galaxy S II Original Android Development] lpsi2000:
One of the great challenge with this measurement is time. Most PPL move on to other kernels or builds before investing the amount of time it take for this measurement. The other factor that makes it difficult to do is the fact our usage pattern, location, service provider, signal strength, etc... are different for all of us.

I think it will easier to get the stars to line up :p

Nonetheless for me, it normally take at least a couple of days, a few discharge / charge, and the same usage pattern with the same ROM and Kernel during that time period. I think it takes at least a day for everything to settle and a day or two to start seeing the truth.
[Galaxy S II Original Android Development] paul88gt:
best kernel ever v2.2 beta6.
[Galaxy S II Original Android Development] KcDaRookie:
I always have the possibility to recharge my phone during the day, that's the great benefit working for a communications company where you at least have your laptop with you and can recharge it over USB and I also have an USB-adapter for my car so no problem with that ^^

But the most convincing thing letting my phone alone for 8 hours without letting it be charged in that time is: I only have 5-10 seconds of partial wakelocks over night since I have the phone an this wakelocks are due to the usage of the phone as an alarm clock ^^

So nothing awesome about it, just knowing how to handle my phone ;)

Plus I have the best kernel ever so how could there possibly go anything wrong? ^^

[Galaxy S II Original Android Development] navalynt:
I had that happen once so far in beta 6 myself, smartassv2 and min clock set to 100mhz. I upped the min back to 200mhz and have not had it happen again.

I have never used a phone that runs as smoothly as the SGS2 with GalNet ICS MIUI ROM and the beta 6 kernel. For kicks I turned off the second core and underclocked to 1Ghz, still just as buttery smooth.

Perhaps upon release you could rename smartassv2 to lardass because of how smooth its gotten?

+1 on MIUI ICS and this kernel. Very nice combination.
[Galaxy S II Original Android Development] Radikaal:
2.2b6seems to have the greatest batterylife of all kernels i tested, no lag in games, browser and mostly smooth. Do however notice some lag from time to time after many hours of sleep and right after wakeup in launcher, but its very little. However i think 2.1.1 is the smoothest you have released yet @sio scheduler. But at the expense at batterylife (i think, going to test a full charge with 2.2b6).

I got 5h30min screentime and 2d6hours with 2.1.1 with pretty much the same usage as my best result(6h Screen on 2d with speedmod k2-13). However probaly would have gotten much better if i had 100MHz at lowest, ran with 200MHz.

Don't know what you've done, but must say since 2.1.1 and forward a huge performance improvement, atleast in smoothness and snappyness, used to this kernel from time to time before and always was disapointed with that matter since everything else is just great, but now its fantastic.
