so with ragemod I have the voltages tab back in setcpu?
[Galaxy S II General] TimmehPS3:
Yes you will... I have ;)
[Galaxy S II General] m2smoe:
Do you have a USB jig? Turn the phone off completely, put in the jig, wait until you're in download mode, remove jig, hook up to PC via USB, flash with Odin. Perhaps that will do the trick.
[Galaxy S II General] ithehappy:
I don't have a Jig.

Edit- I am trying to re-flash the firmware again. What are these options, Clear Phone EFS, Phone Bootloader update, Re-partition and Flash Lock, will any of them do any good?
[Galaxy S II General] m2smoe:
I don't know, but you should not try them out, you might brick your phone. Make sure you know what each does and if you can use them before you try!

Also, a USB jig is a must-have with this phone. I bought one for 5e off ebay and it works perfectly.
[Galaxy S II General] ithehappy:
Yes, unless the phone does something weird. Anyway, right now the phone isn't turning on at all, really embarrassed, now I really need this as I need to see my contacts.

I shouldn't have experimented and played with UV stuffs, shame on me.

Regards.
[Galaxy S II General] m2smoe:
You should have done as I said: start from stock UV settings and go down 25mV by 25mV, doing stabilitytest everytime you go down a step.

That's a requirement for any kind of overclocking/undervolting, for any device, including computers.

If I were you I would turn the phone off, and take out the battery, and leave them for a couple of hours. See if that helps.
[Galaxy S II General] rocketpaul:
If it boots again, quickly try an flash stock firmware. If it continues to shut down, buy a jig reset the counter and take it to a repair center.
[Galaxy S II General] abhi021:
beofre you Reflash the firmware, clear to factory reset, clear cache, clear Dalvik all from recovery mode and don't reboot the phone. Put the phone off and go on to download mode by pressing volume down + home key + power. Once in download mode flash the firmware through odin. Try with flashing the single firmware tar file.

If this doesn't work download the stock firmware from samfirmware.com that comes in three parts i.e. PDA, phone & CSC file. It should also come with PIT file. Select the individual file respectively in ODIN. Also note to select re-partition. re-partition is to be selected only when you files in three parts and NOT if its a single tar file. Instructions are also given on samfirmware.com

Flash it and let it reboot.

Hopefully this should work.
[Galaxy S II General] goldbergx:
What all settings did you use?

If you have a kernel on your SD Card, boot to CWM Recovery using "Volume UP + Home + Power" then flash that kernel after that - if you have a kernel that does not allow under-volting then that would be your best bet.

EDIT: Just saw that the post I quoted was from some hours ago.......
[Galaxy S II General] jody2k:
I know this isn't a benchmark but I run my sellphone for 2days and 4 hours now and the battery is 54% left:

Batista rom

KH3 modem

speedmod T27 kernel

setcpu @ max 500mhz (did'nt noticed any delays or slowing things to be honest when working with the phone)

+- average use: calling, sms'n, surfing, xda app

so if you count my sellphone battery will go 4days easly within average use :) this is amazing! normally it was 2days max (without setcpu), now it goes double :D
[Galaxy S II General] m2smoe:
If you don't play games, or watch HD videos, its not surprising. I don't know why people say this phone has bad battery life.

Could RageMod v2 t27 make the same time of speedmod t27? :rolleyes:
[Galaxy S II General] m444266:
ninphetamin 2.0.2 w/ BLACK bg result out

I think RageMOD will be near or same with SpeedMod T27 if they have same voltage setting by default since there is no OC/UV on my part.

ANYWHOOO... Result with Ninphetamine 2.0.2 (so far the worst performer, 1st pass) but now with BLACK background instead of white is posted!

Next RageModT27
[Galaxy S II General] GadgetCheck:
RageMOD is way better
[Galaxy S II General] TechSilver13:
So are you doing a black screen fir all the kernels now? I bet speedmod27 would be insane with a black screen.
[Galaxy S II General] joelteixeira:
Yeap, it's the best battery experience I have since nokia e71.

Sent from my lite'ning fast GT-I9100
[Galaxy S II General] m444266:
i wish but.. that will take too long. :D I want to enjoy my phone once in a while too.. so I'll just assume that battery life will last approx 3 times longer with a black background vs a pure white one both on highest brightness. whatever our background is, it will surely be between those. we dont want to waste money spent on a great device with great screen if we just put on plain black bg.. unless that's your preference. ;) this will give us instead an idea how our current theme/display will affect the battery. if your current theme is generally light and you want more battlife, then maybe consider a darker theme and get some more juice. again its our choice.

ANYWHOOO... looking good for RageMod v2 T27
[Galaxy S II General] joelteixeira:
Hi mate,

Just to let you know that niphentamine 2.1.3 and SpeedMOD 28 are out.
[Galaxy S II General] m444266:
aww heck.. not even done yet with ragemodt27 and probably ragemodt28 will soon come too. :|

btw, thanks for letting me know, man!
[Galaxy S II General] zzz777:
you missed one of the most importants kernel in your benchmark

CF-root

http://xdaforums.com/showthread.php?t=1103399
[Galaxy S II General] m444266:
I already have stock kernel on my list. cf-root is stock kernel with superuser,busybox and CWM preinstalled so you don't have to go insecure kernel and install those one at a time.

you probably missed one of the most importants page in this thread

And here we go again!

Day 4 is it? Here we go!

Kernel:

2.6.35.7

hardcore@speedmod-s2-k1-t27 )

Rom:

DarkyROM XXKH3 Base R2

Drain Time:

5584 Seconds

4.147V to 2.815V

This one FELT like it lasted a long time (two episodes of Merlin instead of one and a bit), definitely got my best results thus far, even though i forgot to turn off GPS, auto rotate, etc.

Even though nothing was accessing the GPS or wireless radios it may or may not have skewed my results.

Keep in mind, my tests are under the most extreme conditions, even a couple minutes means a lot of regular use.
[Galaxy S II General] abhi021:
Looks like it's raining kernal every alternate days.

I have tried testing the Ragemod v2 - T27 kernal, from first 2 hours on idle with screen on, looks like battery consumption is slight higher may be 1-2 % than the Speedmod T27.

However since being an off day - family day ;) will not be able to make the complete test of 6 hr 20 mins. Will post the test results tomm.

Further test coming up will be -

Ninphetamine 2.1.2

Ninphetamine 2.1.3

Speedmod K1-T28.

NOTE: m444266 : Thanks for putting up the details on the 1st post.
[Galaxy S II General] m444266:
RageMod v2 T27 result out

Done with RageMod T27..

still thinking if I should test SpeedMod T28 and/or Ninph213. not quite sure too much have changed from their previous versions. what do you think?
[Galaxy S II General] jody2k:
say whaat?? ok try to run your phone more than 2days with a standard firmware, you will see what i'm talking about, with a average usage you won't get past 2days my friend :)

atm: 2days 18 hours: battery 41%

i wen't yesterday on party also, did some sms'n, and film, taking pictures that makes me a average user, with this usage I could'nt get past 2days

no i go 4days without prob ^^ setcpu for tha ownage
[Galaxy S II General] desmes:
That sounds quite impressive ! Would you share your configuration , please ?
[Galaxy S II General] abhi021:
Speedmod T28 changelog says rebuild from new samsung update2 source code, it'll be good to test this knowing how much has it changed over T27 in terms of usage.
[Galaxy S II General] jody2k:
@desmes

Batista rom 3.7.2

Speedmod T27 kernel

KH3 modem

setcpu @ 500mhz (without voltage mod)
[Galaxy S II General] m2smoe:
Plenty of people do it, and without underclocking to 500Mhz, which is totally lame when the phone is 1.2Ghz stock.

Also, plz post screenshots of battery use, including a screenshot of the battery graph.
[Galaxy S II General] desmes:
Thank you ! Seems I have to try some more kernels and roms ... :)

I've been mostly on Darky's , because of the ease to skip all bloatware from Samsung.
[Galaxy S II General] m444266:
thanks.. how about Ninphetamines changelog? can someone explain what kallsyms is and so what if it was enabled? also that intrfms fix doesnt seem to be much..
[Galaxy S II General] buxz777:
you should try leomar and his kitchen also very very easy to skip bloatware :-)
[Galaxy S II General] goldbergx:
kallsysms helps in reading logs for debugging. Will not affect kernel performance
[Galaxy S II General] desmes:
Just flashed it after reading more carefuly in Revolution Rom v2.6 Base changelog that skipping bloatw can be done easily :)

Seems quite interesting to be able to choose from the kitchen :)

Wonder how with SpeedMod s2 k1 T27 , for example , you can have longer lasting battery without being able to UV in SetCPU / like in Ninphetamine / ?

What other kernels support voltage control in SetCPU ?
[Galaxy S II General] jody2k:
2d 22u

battery: 38%

how do you take screenshot again?

Results for Ragemod v2 T27 - Litening 6.1

Some how managed to pass the test today inspite of family commitment with Ragemod V2 T27 kernal. :)

Undervolted with the same parameters as done on the ninphetamine 2.0.2 to compare how it performed against Nin.2.0.2 & Speedmod T27 by making use of the Undervolt feature that comes with Ragemod.

So far worked out the best with 53% battery left out after 6hr.20mins

Undervolt parameters : 1200 mhz- 1175mv | 1000mhz - 1100mv | 800mhz - 975mv | 500 & 200mhz - 875mv |

Sorry & thank you very much.
[Galaxy S II General] m2smoe:
That's nice, but you have a 20% charge in there, so it doesn't really mean anything. Maybe you used phone alot before charging, charged, then didn't touch phone and got 2d22h. Also plz post a screenshot of screen on time (press Display in the list)
[Galaxy S II General] jody2k:
yes I saw it, but strange enough it didn't charge :/ just plugged usb in for 5mins or so

but no prob, if you guys don't believe me I will redo the whole thing :)

screen on time is 2U30 min
[Galaxy S II General] m2smoe:
No I believe, but I also believe your screen ON total time is under 2 hours, which is why the phone lasted this long. If your screen ON total time was ~4 hours, you wouldn't get more than 24-36h like I do.
[Galaxy S II General] jody2k:
screen time is 2U30 min :p

edit: yeah well for me it's the best battery time I had (I just doubled my battery life) thats good enough for me ^^ there will probably be some that does it better
[Galaxy S II General] m2smoe:
Yeah, as I thought :p

[Galaxy S II General] xSmooth-:
Soo jealous when seeing people getting more than 15 hours out of their battery.

I wanted to test something at night so I fully charged it when I went to bed.

I woke up 6hours later, looked at my phone and saw the message: "Battery Low"

Wi-fi off, received 10 Whatsapp messages and 1 text message.

I now installed BatterBatteryStats and praying this gets fixed.

Stock firmware btw.
[Galaxy S II General] jody2k:
Why using stock? no wonder you dont get more than 15hours, try one of our great roms here in xda xd
[Galaxy S II General] xSmooth-:
To be honest, max I'm getting is 7 to 8 hours.

Last friday I was working 8 hours, did not touch my phone.

Few messages blabla, came back home..phone off.

I'm new to Android ( Had it a while on my HTC, dualboot WM) so rooting is something I want to really understand haha.

Even though people say it's not hard.

But still, I have an high-end phone, and my Vodafone plan I currently have isn't cheap.

So I expect a phone that works properly with the stock firmware.

But I'll look into rooting and stuff haha.
[Galaxy S II General] jody2k:
well I must say 8 hours is really pour battery life, is your wifi on? try to shut down some battery sucking programs as wifi sharing manager, social hub etc
[Galaxy S II General] m444266:
no prob.. more or less under the same conditions, yes. altho it is unlikely the your normal usage will be under the same conditions so you'll probably get more.

oohh 7-8 hours even with screen timeout, get out of stock FIRMWARE. liberate your phone! :) rooting is something like installing a door to a cage and you hold the key. while that doesnt improve your battery life, outside the door there's vast number of ways to improve both battery life and performance.
[Galaxy S II General] Lenunited:
to be honest.

Well it is only my 2nd charge but im getting horrible battery life of out Speedmod T27.

The standby overnight drained 3% in deep sleep, and if i use the phone its dropping by %1.

Anyone have any tips for calebrating the battery?
[Galaxy S II General] m444266:
Do tell us other details such as firmware, apps, idea of your usage, etc so other people might help.

what do you mean 2nd charge? 2nd charge since SpeedMod or ever since?

btw, people are probably going to ask have you calibrated you battery?
[Galaxy S II General] samaxen:
Hi m444266, can you test Ragemod v1 T27. I think the new Samsung 2 sources is causing higher battery drain. The v1T27 is purely based on T27.

Whereas v2 T27 should be equivalent to T28.
[Galaxy S II General] Lenunited:
Im using

Revolution 2.6

By calibrated you mean killed it to zero then full charge? then yes

My apps cosist of Games and Utlities none of which run in the background.

While the phone was in deep sleep i was getting %3 battery drain, which doesnt seem right.

2.0.2 niph seems the best so far.
[Galaxy S II General] m444266:
I did.. that the ragemod i tested was v2.. note that no OC/UV done on my part.

full charge > clear battery stats > drain till power off > then charge it up again.
[Galaxy S II General] m444266:
stable setCPU underclocked and undervolted configurations and profiles, works only on some kernels like ninphetamine or ragemod, etc. read about them and if the feature difference doesnt concern you, go with ragemod probably so you can use setCPU. use generally darker wallpaper/theme. probably some juice defender even if its the free version one. probably a task killer as well to kill processes running on background when you phone is on asleep/stand by. you can easily go beyond 6 hours.

ANYWHOOO.. anyone think theres a point in me testing speedMod T28(w/ update2) when I have already tested RageMod v2 T27(based from speedMod t26 w/ update2)?? since i dont tweak voltages and run them in default.
[Galaxy S II General] ithehappy:
Absolutely negative on this. Stock firmware could give you same battery backup if not better than a Custom firmware.

Besides, its good to know that you've installed BBS, but don't expect it'd do any good to save juice directly, the purpose of that app is to show which processes/apps are running on background, so that you can do something about it. So keep checking the 'Partial Wakelocks' option.

Regards.
[Galaxy S II General] m444266:
but isnt ragemod v1 t27 based on speedmod t27, only with UV option.?

and ragemod v2 t27 is based on speedmodt27 w/ update2 sources also with uv option, which basically is like speedmod t28 w/ uv..

kind of confusing. ;et me put it this way.

ragemod v1 t27 = uv + speedmod t27

ragemod v2 t27 = uv + speedmod t27 + new samsung update2 sources

but

speedmod t28 = speedmod t27 + new samsung update2 sources

therefore

ragemod v2 t27 = uv + speedmod t28

i have tested speedmod t27, is there point in me to test ragemod v1 t27? also

i have tested ragemod v2 t27, is there point in me to test speedmod t28?

ANYWHOOO... change of plans until that's answered.. testing galaga instead for now.
[Galaxy S II General] m444266:

[Galaxy S II General] m444266:
yeah.. you may want to upgrade to 2.3.4 first. not thinking of custom?
[Galaxy S II General] m2smoe:
Look at those wakelocks, they're what's draining your battery and keep your phone from going into deep sleep:

DoNotGoToSleep (com.twidroid.UberSocial): 15 m 3 s (903 s) Count:31 2,2%

FacebookService (com.facebook.katana.Facebook): 36 s (36 s) Count:12 0,1%

Disable/uninstall those, and you should get better battery life already.

ANYWHOOO change of mind. going LR 6.1 with speedmod t28 .. shouldn't affect anything very much anyway..
[Galaxy S II General] Hacre:
Didn't read all the thread but this is utter nonsense and to say this as a supposed "ROM developer" you should be ashamed of yourself.

Odexed code is arguably faster and boots quicker because there's no need for dexopting, it's already done in the odex file. Deodexing allows one advantage and one advantage only: Theming.

Also for this thread to be of any use at all, then all tests need to be carried out on the same device with some clear test parameters outlined and identical environments for each and every test.

Alrights guys, I succeeded my 4days battery test here's the results:

As you can see I have total screen usage of 3hours with the phone running 4days

note: you see a charging notification, thats strange because i did'nt charge

(exept for the +-5mins callibration with USB because I needed to copy some foto's and video's to my computer, so I think that's the reason it gives a charging notification in the bar).

If it's needed for some people I will redo the whole thing, but i'm pretty shure I will get +- the same results again ^^

My settings are:

[Galaxy S II General] m444266:
already in 6.1

I've already moved to LR 6.1 .. so if i test ninph213, it wouldnt be comparable to my previous ones until I test the same kernels and came out with more or less the same results. if that happens then t just means 6.0 doesnt differ much with 6.1 in terms of battery life. cant say that with other custom roms tho.

anywhoo.. still calibrating my batt from a rom changed. apparently calibration really does help since i only got 3h 32m with speedMod T28, fresh from a rom change. will not post that yet.
