Thank you, few questions:

1. How to you uninstall system apps? Root App Remover?

2. I'm using GO Launcher Ex & accordingly GO Calendar widget. Is it battery consuming same as stock one?
[Galaxy S II Android Development] shahulvm:
All GO* apps connect to the internet. While installing they would seek your network communication permission. God knows why would it need to connect (even the keyboard).

The apps listed by me dont connect to the internet unless needed. Try keeping the GoDialer in the background mode and check the cpu usage and data usage ;)

Ex-dialer is the closest you can get that looks like Go Dialer..

I remove apps via scripts or using a rhythm software file manager.

If you pay attention during installation of the apps, then it save you a lot of trouble.

My philosophy is to get the maximum battery life!!!!!
[Galaxy S II Android Development] pissyhun:
i think some of u forget that u are using a smartphone. its function is for internet browsing and mail, playing games, listening music, chatting with friends. if u use it just to make 10-20 calls and some messages over 3 days then no need to buy a 450 $ phone. i think u can buy a 20$ phone to do same thing. this is not a philosophy. nothing to be proud of.
[Galaxy S II Android Development] shahulvm:
@pissyhun,

Let me make it clear mate. I am not proud off, I just tried to stretch the standby time. I tweaked few things and removed even more bloated apps. I am no way arguing or saying mine is the best or my usage is the best. This is just my light usage, for normal usage i get around 2 days. I am more comfortable browsing the net,xda, mails using my touchpad or macbook...

Am just trying to help in a way I can, if your not happy with it. Please ignore..

have a good day and advance wishes for the New Year to you and all the members here..
[Galaxy S II Android Development] mb:
I'm well aware that my Smartphone battery will burn when it's being USED but STANDBY should drain hardly anything, nothing ideally. This is the issue. This is what Phenomenal excels at.

Nearly up to 3 days use now with extreme 2.0. Astonishing.
[Galaxy S II Android Development] pissyhun:
i dont understand why u show us that u can strech you battery life over 3 days mate. i dont understand the reason for it. thats why this was my answer. sure i have nothing against you. but i think the most of the xda users are not interested in something like that.
[Galaxy S II Android Development] bervin:
that's where your wrong then. Read around, longer battery life is always talked about
[Galaxy S II Android Development] Fishawy:
On the very contrary, I believe most of the XDA members are always interested in extracting few extra drops of their battery juice! Some might do it in a certain way, others might do it in a different one, but in the end most of us aim to the very same goal.

I - for one - am very interested in shahulvm's post. :)
[Galaxy S II Android Development] pissyhun:
interested in getting more battery life without using the phone?
[Galaxy S II Android Development] Fishawy:
No Sir/Ma'am, I'm interested in almost stopping the battery-drain in standby times, interested in consuming less juice with normal usage, and interested in not being forced every now and then to run like a maniac looking for a charger :). An extra 1% battery could, I dunno, save a life maybe?

In my humble opinion, his post and Fenomeno's kernel are on the same page & addressing the same issues. You might like to use your phone in a way, but that doesn't cancel the fact that there are others who use it in a different way.

Cheers :)

[Galaxy S II Android Development] shahulvm:
Okies Friend...when we put forward statements, its best appreciated with evidence. Without results, statements become hypothesis. My post of showing the standby time was meant to prove a point that the kernel was good for daily usage and as well for standy times. Good kernel is something which can perform well during daily use and also help to reduce the drain during idle times. If I were to go with default apps, my standby times could have been screwed (this is where the savings come from). If I were to say this kernel has potential to stretch 3 days, few would believe it without evidence.

Also, if I were to suggest to use this app or that app, none would go by, rather come back and blame the kernel. As a matter of fact, my post was to show that the kernel was very much a capable one and all you need to do was to tweak the phone a little and use alternative apps to get the best. I dont need to prove the effectiveness of the daily usage of this kernel, as everyone using the kernel is an evidence of it. Secondly, another member has also posted about various benchmarks and overnight drain. I ventured into a space which was untested and that is the standby time. Most of us charge the phone when its battery level goes below 30%. It takes 2-3 days to comment right on the kernel, that is combining the daily usage and the standby time.

If you can configure your phone to have excellent deep sleep, then am sure you can extract maximum juice from your phone.

Mate, hope I was able to clarify the point as to why I posted them. If not, pls pm me and I shall explain it even better.

why you are so polemical?

if you don't want to read this things,go ahead and don't answer..it's interesting for a lot of people,if you disagree with that,don't interject!:p

I seem to have understood that you are one of the few who do not care about this thing ...this does not mean that others can serve to..
[Galaxy S II Android Development] BrandoHD:
If you are not interested in getting the most from your battery, it seems you are in the wrong thread, the philosophy behind this kernel is clear. You need to sync your comments with the threads you browse.

Results for SpeedMod / void / Phenomenal / 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 XWKL1 ROM (Modem: XXKL1).

For stock kernels, I was running on the corresponding stock ROM.

Always using the Samsung's standard / stock 1650mAh battery.

Tested Phenomenal 2.1 black Extreme version on XWKL1 and added its results.

Here are my current results:

Benchmarks

Battery stats

The battery saving in mixed usage of Phenomenal 2.1 black Extreme is very good, but I have to redo the over night battery test. New Year's Eve was not the best night for testing :-(

Too many emails, Skype/Talk/phone calls, short messages, etc. for having a "normal" night.

As soon as I have redone this test, I will post my updated results.

Happy new year from Germany to everybody around the world !!!

Make another cycle and then try to set loadh to 80 by script. I think you cannot judice a battery on the first day of year
[Galaxy S II Android Development] fenomeno83:
If you say that noone use blue version, i will not release next time and use only speedmod k18 as base
[Galaxy S II Android Development] pissyhun:
using both phen medium 2.0 and 2.1 and i like 2.0 more. this after 3-4 cycles.
[Galaxy S II Android Development] Manitax:
I had 2 sod with extreme black stock freq.. one was after a phonecall.

With extreme 2.0 i got no problems.
[Galaxy S II Android Development] fenomeno83:
Thic can appen with 2.0 too.settings and base are the same
[Galaxy S II Android Development] fenomeno83:
Can you make this test? Reflash 2.0 and make test. After reflash 2.1 and make test. If your feel is again that 2.0 is better in battery life and not only a case, try in phenomenal 2.1 put loadh script with value 80(to verify if works, after reboot see sys/module/pmhotplug/parameters and open loadh file to verify that has 80).

To get best balanced between battery and performances i need not only your feedback, but i need to understand if some behaviours are only a case or are kernel related.

for this reason i need also your test to understand more..

This is for all people:more active tester=better kernel
[Galaxy S II Android Development] ziroxs:
Sh sry. I thought u searched for windows. I use scriptmanager from market
[Galaxy S II Android Development] Karpfenhai:
back on 2.0 extreme, got sod on 1.0 if battery is lower than 5%, will test now and report.. btw, happy new year ;-)

Swyped from my %s using XDA App.
[Galaxy S II Android Development] fenomeno83:
With extreme can appen with 1.0,2.0,2.1...voltages are the same and i don't think that loadh influences this.some people write that with 2.1 extreme haven't freeze, while 2.0 yes..it is only case..if you don't want random freezes, use medium or normal
[Galaxy S II Android Development] Karpfenhai:
your right, but it only happens if battery is under 5%, i deleted my powersaving profile on set cpu which denies more than 200mhz, we will see.

Swyped from my %s using XDA App.
[Galaxy S II Android Development] fenomeno83:
Ok...but can appen with 1.0,2.0,2.1..it's related to extreme voltages(in your case in low frequencies) and not to phenomenal version.so, i suggest to don't use setcpu
[Galaxy S II Android Development] It_ler:
I prefer black version based on SpeedMod K2-18, as I am fan of CWM5.

But if I have enough time, I might test blue version as well.
[Galaxy S II Android Development] frige:
Flashed 2.1 blue stock medium last evening. Came from 1.0. Looks very promising for me - at least same battery times like 1.1 for me (low use case).

Once tried 2.0 extreme -but my S2 did have problems with extreme voltages.

thanks for the update !

for me best battery kernel

Can not seriously compare blue with black - but reding the forums i think xx-16 is better for low use profiles...

i use setcpu and put this values in advanced tab. i use conservative gov. i need to make the file with loadh in init d folder? or is just enough because setcpu does this?
[Galaxy S II Android Development] shahulvm:
Increasing the sampling rate to 120000 could help a little. loadh values are to be set in init.d folder
[Galaxy S II Android Development] Tyrol:
I put the modified hotplug script into /system/etc/init.d & rebooted but the loadh value in /sys/module/pm_hotplug/parameters remains as 60, although I've already rebooted. Twice, even.

could help if you can set a delay 15seconds before the init.d scripts are executed by using sleep command

hi thanks for the advice man.
[Galaxy S II Android Development] shahulvm:
You should be very quick to observe it. 2.1 extreme take atleast 0.5 second for the screen to turn on, else it just flickers for a split second before turning on. So, I went back to 2.0 extreme and all seems fine now.

I tried Googling & tweaking the permissions of the hotplug script but it just wouldn't change the value in loadh. As a last resort, I changed it directly via a text editor. Is it alright for me to do that, or will there be problems with doing this?

Edit: I guess the loadh values don't persist through a reboot. :( Will someone be so kind as to give me some pointers/guides to working this out please? Thank you.

[Galaxy S II Android Development] :
Ok, haven't read this.. Yes for a comparisone of this two kernels regarding battery, I was talking.. Although it is to dificult because siyah has many many settings..
[Galaxy S II Android Development] It_ler:
That's correct.

In order to get a result that anybody can reproduce, I think that I will test Siyah kernel on unchanged default settings.

UV/OC, etc via (init.d) scripts would make a kind of "unique" kernel base and does not correspond to other kernels in my list.

So, it would be a Siyah "out-of-the-box" kernel test, which could be individually customized/optimized by everyone on his own phone.
[Galaxy S II Android Development] :
Mate I was about to pm you to suggest making a big joint thread with all your results and stuff :)

Will out test syiah with each governor available I hope?

[Galaxy S II Android Development] It_ler:
As my battery tests take some time (at least one battery cycle, sometimes I need two cycles for each kernel), and as I have not much time, I do not want to make anything "big" from it.

I started to test the different kernels under "nearly" same conditions for myself to find the best-balanced ROM/kernel combination for my phone and my usage.

Once started to list my results, I thought it would be "fair" to share my results with the developers of the kernels to give something back ... maybe they can use some results to improve their kernels.

And so I posted my results ... and shared them with the xda "community".

That's why I won't test all available kernels with every settings.

I have to focus on some popular and already tested as being "good" kernels with default settings.

Maybe someone else can start similar test series and comparison.

Then we can draw better conclusions from same kernels on different phones with different settings, apps, in different regions, etc.

Is there a volunteer? Anybody?!

Ok, i am REALLY impressed by your Phenomenal 2 Extreme kernel.

I have the BEST standby time i ever had, guess it´s due to the pretty heavy undervolting in this kernel. I must admit i didn´t do much with the phone during the last days but have a look at the stats, really impressive imho!

This is with the 2000mA battery running Checkrom 4 (my own stripped down version, only 189mb) and with the app "GreenPower Premium" which controls my Wifi and 3G). I am using airplane mode during night. K9 Mail is checking every 2 hours for mails, no other syncing on (i don´t need any). This is on second charging cycle with Phenomenal 2 Extreme.

I think i will skip version 2.1 as some people stated they experience more freezes / reboots. Also i am more than satisfied with 2.0, no reboots , freezes, just smooth and fast and looooong battery life. :D

Only thing i´d love to see in a future update would be voodoo loudness feature from Supercurio:
