No deep sleep here even on t31... Roll back to t27 and everything is fine.

I'm on XXKH1 rom.

Thank you for your kernel though... Absolutely the best!
[Galaxy S II Original Android Development] fish80:
Great performances though... Super smooth t31... I would keep it but without deep sleep drains too much the battery...
[Galaxy S II Original Android Development] PerJohnsson:
Heating and battery drain

I have tried SpeedMod before with Litening ROM. I then had severe battery drain and an overheated phone. The solution was to install Ninphetamine and the phone went back to normal.

Today I wanted to try the new K1-T31. So I installed it but got the same drain and overheating. The battery drain is so bad that it drops power even on USB cable. I have heard so many having good battery with this mod so it is a petty I can't get better performance.

Does anyone have a solution to this problem?

I have an SGS 2 bought in Sweden.
[Galaxy S II Original Android Development] hardcore:
There's something else going on then. Sounds like a misbehaving app.
[Galaxy S II Original Android Development] avetny:
testing 31;)

update:

no laggy (even better scrolling), linpack 91, "SO" smooth.

testing battery life....
[Galaxy S II Original Android Development] pvillasuso:
Hi hardcore , 1st want to thank you for your work

Is there any chance to share T26 for download ?

Is the best I have tried since Ive been using your kernels .. but it deleted last week .. :( , and its gone from the OP

Cheers
[Galaxy S II Original Android Development] nicregi:
Thanks for sharing. Trying out t31 now :)

Hope ti solves the deepsleep thingy. I tested t29 today. 7 hours of on (idle) - 2 hours deep sleep, 4 hours on 200mhz.

Was during my sleep though.
[Galaxy S II Original Android Development] xaviero17:
Speedmod T27 and JuiceDefender.

All day moderate use and a lots of text messages.
[Galaxy S II Original Android Development] :
Nynäshamn huh? I remember that name from the Stockholm Pendeltag when I lived in Sweden. Never been to that stop though.

OT: I had a very similar issue with SpeedMod T29 and T30. Extreme overheating and wasting battery like crazy. Hell, I idled on T29 overnight for 7 hours and it wasted almost 60% of my battery... That's crazy.

I also have Lite'ning 6.1 installed. I reverted back to Ninphetamine and battery drain was normal again. Now I decided to try out Speedmod T27 and it works perfectly. Least battery drain I have seen!
[Galaxy S II Original Android Development] hardcore:
It seems that people having the crazy battery drain with the kernels using the new source code are using the Litening ROM?
[Galaxy S II Original Android Development] rdy2go:
+ 1 deep sleep is back, stock h3
[Galaxy S II Original Android Development] fish80:
Hey hardcore,

just for curiosity I put again t31 and after a battery full charge now is going into deep sleep normally... And immediately... Wow! I will test this great kernel!
[Galaxy S II Original Android Development] PerJohnsson:
I will try T27 tonight then. You should visit the endstation. Great place in the summer.
[Galaxy S II Original Android Development] Pfeffernuss:
Using Litening 5.0 and SpeedMod 30 deep sleep works just fine and no drain at all :D
[Galaxy S II Original Android Development] WarriorZ:
sory guys.. just want to make sure..

Im coming from another kernel. niphetamine. For the last weeks I just try speedmod, niphetamine, and mirage kernel. now I want to back to speedmod.

From my past experience I just flash the new custom kernel without reverting back to stock kernel first (flashing stock kernel first) because I dont have any glitches when doing that.

If I want to back to speedmod, I just flash it via Odin right? without care about flash it to stock kernel first?

thanks
[Galaxy S II Original Android Development] jasontschan:
That right, you can flash it via odin or cwm manager, and I suggest you to charge bettery to 100% and calibrate the battery again.
[Galaxy S II Original Android Development] rab1412000:
Yes that is correct
[Galaxy S II Original Android Development] Silverbolt:
No, not just Lightning Rom. I had the crazy battery drain with Criskelo v14 & v15.
[Galaxy S II Original Android Development] zvikam:
How come? I am on Litening 6.1 with SpeedMod 31 and no deep sleep at all. Even though, thanks for the really great work hardcore!!!
[Galaxy S II Original Android Development] gil80:
Nope. I'm using Villian Rom and T31 and only now I got the battery drain. At T28 for example, I didn't have battery drain.

Could be ROM differences?
[Galaxy S II Original Android Development] dzontra11:
Strange...stock rom...t29...no deep sleep at all but great battery life.....
[Galaxy S II Original Android Development] yuvalbar84:
got the same problem here...battery is draining fast

T31 doesn't get into deep-sleep either, ever since >= T28

hopes to see a fix for that one :/
[Galaxy S II Original Android Development] fish80:
Guys with no deep sleep... Don't know why, but I resolved that issue with a full charge of battery... Don't ask me why, but you could try...

I'm on XXKH1 stock rom.
[Galaxy S II Original Android Development] hardcore:
If you're having the "nodeep sleep" problem:

- Remember, there is no deep sleep when the phone is connected to the charger or usb

- Reboot and check it again

- Dial *#9900# and Disable Fast Dormancy, reboot and check it again
[Galaxy S II Original Android Development] adaimespechip:
Stupid question - When loading this via odin, am I selecting the DPA field to apply the Kernel?
[Galaxy S II Original Android Development] robbiekhan:
Nope, you're selecting the PDA one :p
[Galaxy S II Original Android Development] adaimespechip:
Dammit! Thanks bro ;-)
[Galaxy S II Original Android Development] robbiekhan:
Do note though that the yellow exclamation will show on the Samsung boot screen if flashing via Odin so if you don't like that then use a USB jig or use one of the fixes available on this forum.

It won't affect anything being there though.
[Galaxy S II Original Android Development] yaronAD:
here you go:)

I too think that I is the best (was my first) >>> but just install the T31...with many hopes:)
[Galaxy S II Original Android Development] yaronAD:
Stupid question....but what exact. is the "no deep sleep" problem?

If the screen won't shut off?:confused:
[Galaxy S II Original Android Development] iwang:
T31 is better than 28 or 27..
[Galaxy S II Original Android Development] xmfpdlemalnz@hotmail.com:
Please go through a couple of cycles before making no-deep-sleep claim.

On T31 and still no sign of drain but will wait and see
[Galaxy S II Original Android Development] pvillasuso:
Heeeyy, thank you so much man ..

Very nice of you
[Galaxy S II Original Android Development] jbdeq:
I had the problem on Leomar's ROM, havent tried T-31 yet though
[Galaxy S II Original Android Development] aegisfreedom:
How do i know the phone is going into deep sleep or not?
[Galaxy S II Original Android Development] jbdeq:
CPU spy from the market. Free app.
[Galaxy S II Original Android Development] blackspp:
No drain here on kh3 stock and t31

Good combo afaic
[Galaxy S II Original Android Development] hytin:
Deep sleep ok on my kh3 stock and t31

tanx
[Galaxy S II Original Android Development] aegisfreedom:
Thanks.
[Galaxy S II Original Android Development] dartoumi:
Sorry if this question is already asked, but where are the source code patches for?
[Galaxy S II Original Android Development] andresalonika:
Ninphetamine or SpeedMod ? ????:confused:
[Galaxy S II Original Android Development] avetny:
31- no problem with battery...
[Galaxy S II Original Android Development] hung77:
Speedmod is the best kernel for your SGS2
[Galaxy S II Original Android Development] andresalonika:
Thanks a lot!! But im using ninphetamin kernel atm..what if i want to use speedmod's kernel? Do i just flash through odin normally or flash the stock kernel first? Will i lose my apps?
[Galaxy S II Original Android Development] Pfeffernuss:
No idea... Haven't tried T31 yet but this is the result with Lite'ning 5 and T30 so far:
[Galaxy S II Original Android Development] SERGI.3210:
is not entirely accurate affirmation...

I think there are a variety of views for this.:rolleyes:
[Galaxy S II Original Android Development] Jonjungle:
I tried to get it from the market but it says not compatible with my device [galaxy s2] :(

any alternative?

Edit: Ok just realized there is actually an option in SetCPU to see "time in state" in the "info" tab.
[Galaxy S II Original Android Development] aegisfreedom:
How's that possible? I downloaded the same thing, and it works.
[Galaxy S II Original Android Development] rikz112:
ok so i have t27 speedmod how do i change this to the latest kernal t31?? do i flash via odin? or do i use cwm to update ?? help please
[Galaxy S II Original Android Development] WarriorZ:
okay thx for your confirmation :)

anyway I dont do calibrate the battery after 100% charge :(

I think maybe that the reason why Im having battery drain..

calibrate the battery = remove battery status on CWM right?

and what is all of you talking about the "Deep sleep" anyway? :D

as my question already been answered.. YES you just flash via ODIN or update with CWM
[Galaxy S II Original Android Development] elnoxvie:
Update via Odin. there is a flashable cwm in the threads .. search for it but before you do that just in case people tried it and not working.
[Galaxy S II Original Android Development] rikz112:
ok so i flash via odin i get the yellow triangle do i flash stock over it to get rid of this???
[Galaxy S II Original Android Development] marvinhemstock:
or use a jig :) flashing stock kernel you will lose t31 kernel
[Galaxy S II Original Android Development] rikz112:
i dont have a jig i did get rids of it last time when i used t27 i forgot how i did it someone help please?
[Galaxy S II Original Android Development] avetny:
Whats wrong with sexy yellow triangle man??? just leave it ;)
[Galaxy S II Original Android Development] Davith:
This T31 is rock solid. I'm glad the no deep sleep issue is gone for me.

On a side note, I wonder what's wrong with the Tapatalk app and this thread. It force closes every time I try to read it. The strange thing is that all other threads are working fine. I hope it's just temporary, I hate going on the XDA website using the web browser on my phone.
[Galaxy S II Original Android Development] piteyyy:
for all who have battery drain and no deep sleep. try to wipe cache partition and wipe dalvik cache. (no data loss)

this help me.
[Galaxy S II Original Android Development] rikz112:
i know but i would like to learn thats all i got rid when i installed t27

EDIT : SORTED FLASHED BACK TO STOCK TO GET RID OF IT AND FLASHED THE ZIMAGE FILE FOR T31 THROUGH CWM :):)
[Galaxy S II Original Android Development] blaex:
glad to hear the no deep sleep problem has been fixed!
[Galaxy S II Original Android Development] :
Same issue here. But I'm on kh3 + speedmod t27.
[Galaxy S II Original Android Development] Остап:
Yes !

But only T29-31 ones. In 27-28 all are workin fine !

I'm back to T27. Battary life on 31 is very bad. 7 hours only
[Galaxy S II Original Android Development] Остап:
31 was eating battary like crazy but deep sleep was workin perfect !
[Galaxy S II Original Android Development] Davith:
Okay I just don't get it. Deep sleep was working perfectly for me on T31 until I rebooted my phone an hour ago. Now CPU Spy shows it just doesn't want to sleep anymore.

I will try to revert back to T27. It seems my phone can't handle the new kernel sources. I'll try the later versions when I make the switch to 2.3.4.
[Galaxy S II Original Android Development] Остап:
T27 is workin perfect !
[Galaxy S II Original Android Development] Ffbf:
Well, im testing T29 and im very impressed. Light to moderate use, never had this battery life before. I never turn off wifi and 3g so the phone is always connected.

Just had 1 issue, but i dont know if its kernel related. Using setcpu my phone got sleep of death everytime i connected a charger (200 Mhz screen off). When i set it up to 500 its all good.
[Galaxy S II Original Android Development] nechmadi:
it's not light , it's almost no use .

flashed t31 , hope for good :D
[Galaxy S II Original Android Development] Ffbf:
Indeed, but as its connected wifi/3g 100% of time, running viber, pushing a gmail account and updating launcherpro facebook widget every hour i said light to moderate.

Of course this is nothing to most of you guys :p
[Galaxy S II Original Android Development] huuub:
Still that battery life is impressive :s
[Galaxy S II Original Android Development] blackspp:
Deep sleep is working perfect with t31, full day use and power sits at 62% which compared to yesterday is a good 50% improvement (sort of same usage).
[Galaxy S II Original Android Development] yuvalbar84:
sorry mate, tried to follow all of the above + tried to charge till 100% as a guy here mentioned...still doesn't work, the battery is draining fast. t27 seems to be the last good-battery-life version that was working for me, and for some other guys whom Im talking with.

thanks alot for your help though.
[Galaxy S II Original Android Development] andresalonika:
Will this t31 kernel wipe my apps and data if i install it on top of the one im using atm? (im using ninphetamin's kernel no root) . Thank you
[Galaxy S II Original Android Development] mariotme:
No m8 don't worry nothing will get wiped or replaced other than the kernel itself
[Galaxy S II Original Android Development] blackmumba:
No a new kernel will not wipe any of your apps. The same with a modem.

Only if you flash a wipe rom your apps and settings will be gone.

Cheers

Sent from my GT-I9100
[Galaxy S II Original Android Development] andresalonika:
Cheers guys thanks
[Galaxy S II Original Android Development] Остап:
Really Impressive ! :D
[Galaxy S II Original Android Development] Davith:
So I went back to T27 and deep sleep is now working fine. I'm not sure what could be wrong with the later versions on my phone.
[Galaxy S II Original Android Development] DarkMenTH:
I can't help reading the HDD with ntfs file system..any solution?fuse.ko and ntfs-3g.ko not work with this kernel?:o
[Galaxy S II Original Android Development] ChrisFilo:
Is anyone else experiencing lag in page turning animation in kindle app with this kernel?
[Galaxy S II Original Android Development] FrenchSparda:
T27 is/was a really great kernel like t22 :D
[Galaxy S II Original Android Development] MODKID:
HI

I Am on

KH1 , 2.3.3

can i use this kernal ? should i just download the kernal and flash it throught odin ?
[Galaxy S II Original Android Development] SERGI.3210:
1. yea.....:)

2. yea also

if your firmware is european KH1 is 2.3.4 not 2.3.3 ;)

cheers pal
[Galaxy S II Original Android Development] MODKID:
But am not in the european KH1

i am on the Arab KH1 which is 2.3.3 ** I9100JPKH1 ** ?!! the 2.3.4 hasn't been released yet for our region !!

so can i use it ?

dose it work on 2.3.3 and 2.3.4 ?
[Galaxy S II Original Android Development] iwang:
Am on 31 since yesterday, deep sleep alright, 15hrs battery on normal use, continue testing today with disable fast dormancy.
[Galaxy S II Original Android Development] aegisfreedom:
Im on T31, deep sleep not working. Clear cache and dalvic, wipe batt stat, still not working..drain 10% batt during bedtime..

[Galaxy S II Original Android Development] SERGI.3210:
uooopps u posted threee times the same post...:confused: PLEASE Dónt dump and duplicate posts pal,,

i don´t know if works in a arabic ruu BUT but you can prove to flash it in odin ... if does not operate flash again with your old rom with the kh1 the stock kernel (mode downloader u know ;)))

thinking about we are talking about the same android version (gingerbread), actually the kernel controls the hardware of the device,,, and the device is the same here in europe in asia australia etc...

i think that its going to work properly!:)

always u can revert the changues from odin,,,,

feel free to post here the results,,, :D
[Galaxy S II Original Android Development] LBTaylor1984:
Running t28 doing 6hrs 50mins per 1%. can't fault it really.
[Galaxy S II Original Android Development] gtda:
I'm on kh3 with t31, I've just found using dynamic setting in display gives me no yellow tint. My brightness is always set to 0%

Any one else use dynamic?

Deep sleep working give here too, I do notice my fancy widget clock doesn't update the time sometimes. Which can be deceiving coz it has a battery percentage on it, makes me think my battery is great when its not lol
[Galaxy S II Original Android Development] nofam:
Flashed this last night and lost 8% in around 2 hours. Flashed back to T27 and my phone is deep-sleeping like a baby!

I wonder if there is an issue in the updated sourcecode, as people seem to be having similar issues with the Ninphetamine kernel?

I'm using Cognition 1.51.
[Galaxy S II Original Android Development] jasontschan:
For the deep sleep problem, it may be caused by Samsung update2 source code, Since T28, I found that sometimes the phone will awake by itself, but not really drain too much battery, this problem didn't occurred before version T28.

I am using Leo's v2.6, wiped everything before flash this rom & kernel, for the past SpeedMod version, I don't have this awake problem.

usage of T31
[Galaxy S II Original Android Development] turilo:
Great work!!
[Galaxy S II Original Android Development] turilo:
There any versions that can be flashed via CW?
[Galaxy S II Original Android Development] Lobaba:
deep sleep not working...I even have juicedefender switching off data network at night yet it drains 20++% in 6 hrs. on default rom with KH3
[Galaxy S II Original Android Development] hardcore:
K1-T32:

- Test release using Update1 source code but with new compiler optimizations from K1-T29

It will be good to compare K1-T32 (Update1 source code) vs K1-T31 (Update2 source code) to see if there are any differences in battery usage.
[Galaxy S II Original Android Development] jasontschan:
Just installed, I will report back later:cool:
[Galaxy S II Original Android Development] BAWS:
Just installed it aswell, from RAGEmod v1-T27.

Just lost 1% battery when reboot.

think I lost about 10% before.
[Galaxy S II Original Android Development] m444266:
Awesome, I'll get to this one. just finished with T31.
[Galaxy S II Original Android Development] BAWS:
thank you for taking your time and benchmarking all these kernels
[Galaxy S II Original Android Development] koolshubh:
Can anyone tell me how can I flash this kernal through CWM if its possible... Thanks
[Galaxy S II Original Android Development] beaver2233:
shove the zimage in a flashable .zip or just find the cwm app and can flash it using that ;)
[Galaxy S II Original Android Development] valtamnz:
Just flashed to T32...should be interesting to see the difference.
[Galaxy S II Original Android Development] koolshubh:
Thankss for the help... I jst flashed .tar file through CWM as Flash Kernal and it worked.... :)
[Galaxy S II Original Android Development] Galaxy_Fan:
Download DarkyRom2 Tool from the market.

With these app you can flash the tar file
[Galaxy S II Original Android Development] nicregi:
I am definitely looking forward for this. A quick test earlier and 2h 30m on phone wifi only with a few emails in, list about 1% battery life. That was on t31. Will see how this works out then.
[Galaxy S II Original Android Development] hardcore:
From my initial observations, T31 and T32 have about the same battery usage.

But I don't experience the 'no deep sleep' problem. It might be another story for people who get the 'no deep sleep' problem. Hopefully this problem doesn't happen in T32.
[Galaxy S II Original Android Development] gil80:
Back to Kernel T28.

Battery drain on T31 and 32 is considerably high.

I did not install new apps after changing kernels so the only variable in this equation is kernel changes.
[Galaxy S II Original Android Development] hardcore:
I've figured out how to adjust the brightness levels... I've lowered the brightness on lower levels and this should be in the next release.
[Galaxy S II Original Android Development] fish80:
I thinks there's something strange into Update2 source code... I try to explain:

- Until t27 everything perfect

- t28, t29, t30 no deep sleep (in my case)

- t31 initially no deep sleep; after a full charge deep sleep back. Yesterday made a battery calibration and as result I got NO deep sleep again...

- t32 just flashed... deep sleep is working. Obviously can't speak about battery drain.
[Galaxy S II Original Android Development] Qwerty__-:
i'm considering the best kernel is the T27 too...
[Galaxy S II Original Android Development] Dirkenberg:
Any intention to update su to version 2.3.6.3? Thanks.
[Galaxy S II Original Android Development] fish80:
t32 is a t27 more optimized...
[Galaxy S II Original Android Development] nofam:
Have flashed T32, and will leave overnight at 100% battery with radios off (via Juice Defender). Update to follow tomorrow!

Thanks for taking the time to rework this HC - much apppreciated!
[Galaxy S II Original Android Development] nmsraider:
Good work again hardcore, one question though.

i have installed all the updates you keep posting all getting better as we go. i have never had any issue will no deep sleep nor severe battery drain.

now i am no expert in this field nor do i calim to be, but if you dont get it , i dont get it, surely its a app or the rom they are using causing the problem.

I have never had such good battery life in a phone since these mods since the snake phone days :)

Currently running:

Lite'ning Rom v6.1 XXXKH3

Hardcore@speedmod-s2-k1-t32
[Galaxy S II Original Android Development] marvinhemstock:
i use dynamic and no yellow tint on mine :)
[Galaxy S II Original Android Development] Davith:
It's definitely not caused by an app, or at least not the app on it's own.

Deep sleep is working fine on CF-Root and all Speedmod until T27. Then T28 and beyond started using the Samsung update2 which seems to mess around deep sleep for some of us. It could be caused by an app (among tons of other things like ROM, mods, etc.), but if that's the case it only reacts abnormally when in combination with this update2. If you revert back to CF-Root or T27 then the deep sleep issue disappears. I'm guessing T32 should be working fine as well.
[Galaxy S II Original Android Development] gil80:
Could Android OS be the issue?

It seems that it got much lower since I changed back to T27.

Before that it was about 40-60% (with T31/2).
[Galaxy S II Original Android Development] dzontra11:
T31 works very good for me...deep ..deep sleep.
[Galaxy S II Original Android Development] sebarkh:
It is the second time since t31 when I loose all battery in 5 hrs, while not using the phone... Must check other kernels...

Sent no matter where from. Concentrate on the topic...
[Galaxy S II Original Android Development] vithudu:
Finally i got "deep sleep" at 70% batery life with k1-t32 version; I tried several kernels like ninephetamine 205, 211, 213, and speedmod k1-t27, k1-t31, but only k1-t32 gave me a deep sleep in my mind.

Thanks
[Galaxy S II Original Android Development] Bynar010:
Battery life way better on T32 than the previous few versions. Assume therefore this "deep sleep" issue has gone away for me too.

Unplugged for 4hrs - down to 89% with 45mins of calls in there. Happy with that.
