check what apps are running after reebot and check your battery if the contacs are fused together by mistake

Ask in the battery stats thread .
I would wipe the phone install stock rom do not add any apps .
Set-up turn off data sync etc ,
Fully charge battery wipe battery stats .
Let phone sleep for 12 hours or overnight and check battery usage .

First see partial wakelocks tab. You can post screen shoot here. First of all do next :
Download >>samsung ultimate kernel cleaning script 2.4<<
than download latest cf-root kenel form here:

Place the files on your internal SD-CARD.
Restart to ClockWorkMod Recovery.
Install the kernel cleaning script.zip like any other package.
Install the Kernel of your choice.
Reboot the device.
Set BetterBatteryStats to "Kernel Wavelocks" with "Since Charged" and/or "Since Custom Ref." and see what it comes up with.
I did that. And then installed Redpill kernel. No changes. Same battery life.

My goal for this kernel?
I want to push the limits of this phone to the maximum and takin' it to the limit! Well, it's always fun to overclock, hence Zedomax "OC" kernel. If you want stability and long battery life, see this kernel instead.

ChangeLog:
v.1
-Stable 1.6Ghz Overclocking - 200-400-500-600-800-900-1000-1200-1400-1504-1600 Mhz (thanks to NeoPhyTe.x360!)
-Smartass/Interactive governors added!
-Root
-CWM 5.0.2.3 (thanks to codeworkx!)
-SuperUser App 3.0.5
-SU Latest 3.0
-Custom Boot animation support (copy over bootanimation.zip file to /system/media directory)
-init.d support
GitHub Sources Here
ROM Devs: Would be honored if you include my kernel in your ROM, no need to ask or linking needed, just put it in there for me will ya?
Beta testers needed:
Can you try 1.6Ghz OC with smartass and see how battery life is?
How to Flash Kernel:
You can flash the zip file in ClockworkMod Recovery. You will need a rooted kernel with ClockworkMod Recovery, you can try my stock kernel here to get CWM if you don't have it yet.

Not sure, it COULD be since international is nearly identical to AT&T.
Can you try it and let me know?
I am sure it won't brick it but at the worst you might lose voice or something but it should boot on regular GS2, just have your stock kernel in hand just in case.

Sorry for that, you can try downloading on another browser, the stock browser won't download, I think Dolphin HD works or just download on computer and copy over.
I'll be trying this out tonight and I'll report on any immediate stability problems. I'll also let it run over night tomorrow and I'll update you on how well the kernel's running by then.
Edit 1) This is remarkably stable at 1.6Ghz forced (performance governer). It lasted 30 minutes before crashing on stock voltage. I'm impressed.
Okay I used unnamed 1.02 and it booted but upon benching it crashed and on reboot was stuck with boot animation always on. Had to pull the battery.

Make sure when benching don't set SetCPU app to "set on boot" just in case your phone can't go 1.6Ghz. That's probably what's causing it.
so far so good . first time ive been able to stay oc'd at all. normally itll freeze after a minute at 1400. now been on 1600 for 20 mins straight running tests and all is well. benchmark s are through the roof
Installed fine for me on UnNamed 1.0.3. Long first boot, but after that no problem. Will report back tomorrow after some playing.
FYI, you'll find that there are quite a few people in these forums who are sticklers about following licenses such as the GPL.
hint hint...
tried flashing in clockwork and it says installation aborted
a little bit slower than entropies and less features.. throw in gpu oc and ill be sold.
Flashed it, then put my phone down to charge for an hour to watch the ICS event, when I went back to my phone it was really warm. Don't know if the two are related.
Sent from my SGS II
Very unstable with my test, I can't overclock to 1600 without a freeze.
Seems to be slower than kernel from unknown rom in benchmark.
Any of you getting good overclock with unknown rom and this kernel?

Try this one, it includes the Odin I used, I left out Odin tar file for this kernel because I don't want people Oding kernels and accidentally brick their phones, try the root kernel then flash this in CWM.

hi guys,
i just purchased a second hand s2 and loving it so far! the thing is it has already been rooted and running villainrom 2.0. but i do not know what root method has been taken. e.g. clockworkmod / unrevoked. how would i find out?
i have had some issue with some apps that i have instaled which just disappear. the icon of the app remains but when i select it, it says that the app is not installed.
Villain rom instructions .
They where almost certainly the standard Chainfire rooted Kernel and CWM method .

only problem now is that my battery drains very quickly...i took it off charge around 10:00am and its now 4:00pm and i'm on 35%...but weird thing is i just rebooted my phone and it now says i'm on 13%?? is that normal? :S
i think i may have a fauly battery...my battery goes up and down at different times...
basiaclly it was on 49% and i restarted my phone, it then went to 19% and a left it for a few mins and it went back up to 25% ...can anyone help?
I think you need this:
Flash a wipe stock rom(there are 3 different .tar files). With Odin pda or code file in odds section, modem file in the modem section and csc or multi csc file in the csc section... After flashing the stock ROM, root your phone using the cf-root method and through cwm do a battery stats wipe...
Hope this helps!

NO
If you are rooted with CWM either boot to recovery advanced and wipe battery stats or get Battery Calibration from the market or let the battery stats reset themselves after a few days use .
Stock rom wont fix anything and neither will flashing a three part rom instead of a single file rom .
jje
i am already rooted i will download Battery Calibration and test it with that and post the results...
would buying a new battery be a better option for me?

what kernel, rom, apps do you recommend?
i'm new to this thing but already informed myself. i got the streetware kernel and the original 2.3.6 firmware. i capped the cpu to 300-600 mhz and its good like this but i need an app that autokills services that are hidden. like "Badge Provider" etc. or even better: install a kernel or rom that doesnt include all that ram-eating ****.
.
2 full days without charging
normal usage = no
light usage = no also
flight mode = yes
that is based on my experience.
now im using codeworkx ICS kernel. its quite good for me. quite heavy usage but it last for half day
I/O scheduler: noop
governor: hotplug
autokill services app might consume ur battery more because it have to run again and again.
to kill stock application, maybe u can refer to this
link: SGS2 Removable
credit to the owner (sorry i forgot where i get that from, but im sure its from XDA forum ) but that one is for GB, for ICS im not quite sure. maybe someone in this forum could help us :highfive:

take a look, all it ever display are these 4 things.
even after i use chrome to online for more than 15 mins, it never appear in battery usage.
even default things like android OS and messaging app and other normal stuff that usually appear are missing.
what could be the cause of this?
i reflash the siyah kernal using cwm flashable zip and tried using odin to flash the tar file, but still same problem.
in extweaks, i just underclock it to 1Ghz as max, and 100MHz as min.
other settings remains untouched.
forgot to mention, i also tried clear cache and dalvic cache, still same issue :-(

I did that as well. But not working.
Is this normal for siyah 3.3.2?
Flash the latest Siyah Kernel which is v3.3.3d. I believe the developer sorted a few issues with Kernel Wakelocks and battery issues. Give it a go and report back after a while, not immediately. You have to let these things occur first.

i found the thread above.
in the first post, the author posted his stock battery stats.
look at the first screenshot, just like my situation,
at 47% remaining, it only display the following 4 items in battery history
sceen
voice call
standy
idle
usually stuff like apps, android systems, android OS and other apps that are used will be displayed.
i think this is an issue with siyah.
you mention you are using 3.3.3d
have a look at your battery history, are they only 4 items in there?
i think this may be a siyah thing, it doesn support stock battery history monitor.
edit:
the stock battery monitor is fine after i flash dark knight kernal, it display all the stuff like apps that i used.
this makes me feel siyah is the problem.
if any siyah kernal users would be so kind to confirm whether this is normal siyah issue or whether my phone has problem with siyah. thanks
sigh, just tried siyah 3.3.3d, the latest one,
same thing, no info in battery history other than that 4 items.
whats goin on here, siyah is such a good kernal, but this missing feature is just sad.

I´m using a stock 4.0.3 rom and siyah 3.3.2 and the same issue with the battery usage is happening here. I also optimized the kernel on CWM to battery saving. I´m not sure but as far as I remember this issue was not happening before I´ve set it up this way.
do you know any older siyah version that doesn cause this bug?
i dont mind using an older version

i used the ultimate cleaning scrip,

3.2,3.3,3.4, even the new 3.4.1 also have issue.
i recently learn how to dual boot, nice stuff.
on resurrection rom, battery monitor works perfectly,
but when boot into secondary rom which is sensation rom, battery monitor not working.
so yeah, siyah hates samsung roms.
Hi Guys,
I would like to ask for some advice regarding my GF's S2 Battery.. it seems that I'm in a dilemma which of two is at fault. Occasionally, whenever the battery hits 50% and I'm doing something CPU hungry apps like games or stuff.. it jumps from 50% to 16%.
I've already tried:
* Wiping battery stats in recovery (Using Philz)
* Flashing a new kernel
* Wiping Dalvik and Cache
* Fixing Permissions
and I still experience the ridiculous battery drain. Does anyone has an idea what could be the problem? Could it be the battery itself?
My GF's S2 is using Wanamlite 13.0 and Jeeboo kernel at the moment.
Any advice would be very much appreciated
Try a clean install of stock. Then try a new battery. If you've had the phone for a while (given the SGS2 was released over 18 mths ago), the battery could be on the way out. Even 12 mths of constant use/drain/recharge can finish a battery off depending on how often you repeat that cycle.

Flash to Wanam 12.8 or a version which is ICS.
Wanam 13 which based on LSJ is a leaked version that many users reporting problems with the battery performance.
After you try the ICS version of Wanam, you will see that battery performance is now stable.

I used to have this behaviour before my USB port broke down completely.
Download android assistant, using this app it tells you which apps are using the most CPU, maybe she downloaded a game or something which uses alot of CPU.
Well to those who are interrested that was a battery problem.. I used a non genuine adaptator that damaged the battery progressively
