Battery drain in just 6hrs, 2.2.1 JPY XEU. (while idle overnight), phone was turned off in the morning from 100% before going to bed. (completly drained)
Voodoo kernal with voodoo lagfix/sound.
Ive done a full wipe and installed only the apps from the market (not installed any of my gameloft games)
Not sure yet if this has fixed it but...
Is there Any app i can use to see what the trouble is?

Try the APP "Green Power" from market, it turns off wifi automatically when not in use, plus lot other power saving features.
I too have the same experience previously. now this App helps me a lot.

Sorry to jump in but can you tell me where you found this, I have gone into settings wifi but cannat see it anywhere

If you have disabled GPS and Bluetooth read the following, if not do so and come back^^
1. Go into battery stats and look out for anomalies
2. let your phone run out of power and shut down by itself, if the drain does not change significantly after that.
3. think about your installed apps. chat apps like skype and facebook are evil battery eating bastards.
4. check out whether your modem fits your region
5. Reflash the kernel

how to know to best modem that feet my region please ? i have have tried many of them i all work fine but how to know the best one ?

I had sort of the same problem as well. I downloaded Android System Info and went in to tasks and killed com.seven.Z7.service, and that made it stop use my data transfer 100% of the time. Worth a shot? I think it's the SGS email client, that has been reported before as well. Weird cause I've got push email, but still...

Its definatly a wifi issue, i thought a full wipe AND and fresh rom flash would clear it - but no luck

I just need a clue, wifi driver? Re-partition? Kernel issue?
Any developers know what could cause wifi to keep scanning when enabled?

ive tried countless different roms and full wipes - ive heard of others having this issue on not only the galaxy s, but the galaxy tab and also HTC phones (a quick google search)
so, is this an android issue?
i refuse to believe that there isnt one developer on this forum, that doesn't know the answer and fix to this problem?

Easy Fix... (For the SGS anyway)
Go to... Menu>Wireless and network>Wi-Fi settings.
Uncheck "Network Notification"
Then tap the menu button (to the left of the home button) and tap "advanced"
Select "Wi Fi sleep policy" and set it to "When screen turns off"
Your battery life will improve drastically. Just drain the battery fully, and give it a full charge.
Let me know if this helps you.

It still keeps scanning for networks whilst im connected to my home wifi.
I dont want the wifi to disconnect when my screen goes off, i download and dont want it.switching to my data allowance just because the screeb turned off.

Unchecking Menu>Wireless and network>Wi-Fi settings.>"Network Notification"
You get no scanning for open networks so maybe you stop to scan networks while associated.
I think this is a problem with the modem.bin try to flash other one maybe JPY, JPU or JPM

Can you please check in wi-settings and see if it keeps scanning every 5 seconds when already connected to wifi.
... It may be normal behaviour, but.i doubt it.

eh17 reboots - narrowing in on the issue

from what i've noticed
it happens when closing the keyboard under certain circumstances
possibly only during sms messaging
i was able to duplicate a reboot sending/receiving a couple messages today
i had just received messages and then closed the keyboard
immediately i noticed the samsung logo
just seeing if this strikes anyone else's memory as being the point of occurrence
this was with eh17 and mkasick kernel
i have also seen one random reboot with my phone just sitting there
that was eh17 with eh17plus kernel from chris41g
but i also got the sms keyboard close reboot then as well at least once
i posted a kmsg for mkasick but he didn't see anything
just hoping to document the occurrences to help narrow in on the exact issue.
save the whining for another thread...thanks
i have a lot of bloat removed.
launcher pro
no animations
2 minute screen timeout with keyboard set to same as screen
auto rotate off in both settings and launcherpro
stock sms app

Sounds more like you have a loose battery. Random reboots occur in GB leaks when phone is sitting idle. It was found to be a voltage and deep sleep transition during partial wakes that was causing it. The fix was posted in this forum using Tegrak and SetCPU combination.

Here's what works for my phone:
SetCPU
OnDemand 100mhz/1000mhz
Screen Off: 100mhz/200mhz
Tegrak (Make sure you buy it for the newest version.)
OnDemand 100mhz/1000mhz
100mhz @ 1000mV
200mhz @ 1025mV
Edit:
If it is a loose battery, you can always jam some cardboard back there to make sure. I can't remember where the link is to the SetCPU/Tegrak, so I just posted my own settings for ease. It does seem to vary per phone, just like overclocking/undervolting, so a bit more reading/tinkering might be required.

my reboot issues happened a lil over 2 minutes into a phone call on every rom I tried so I went back to eg22

The fix for reboots is a page or 2 down here in General called "Possible fix for random reboots"

Also running "stock" EH17 with the mkasick compiled kernel, and haven't had any reboots in the last 4 days. I use the keyboard to send sms many times without problem. Sounds like a mechanical problem to me. I've heard other people with loose batteries or worn battery contacts have exactly the same issue. Try wedging a thin piece of cardboard into the space along the bottom of the battery and see if the problem goes away.

definitely a loose battery
i'm dumb
i'm running the 3000mah with extended door
i just set it down with a bit of extra force and yep reboot
thanks people

didnt know there was a fix for the random reboot.. i have 2 try that out its funny that it doesnt happen while plugged in

It doesn't happen while plugged in because it runs constantly at 100 Mhz and does not go into deep sleep. That is how we narrowed down the issue in that other thread and added the screen off profile to SetCPU.

I fixed my loose battery by sliding a half credit card ... Actually an old Kroger card... In the back of the phone. Tighter and zero reboots. Specific to the battery anyway. Cm7 does not reboot.

For me at least, the mkasick compiled kernel on EH17 doesn't reboot either. With the standard kernel it rebooted within a half hour of install.

Combatting the Sleep Of Death

Not sure how to search on the XDA app, so please forgive me if this is already a topic... does anyone have any tips/tricks for avoiding the Sleep Of Death?
-XDA Premium on CM7 Nook Color

What version CM7 are you on?
Latest SOD fixes were put into a kernel which is available as separate zip but have not made it into a nightly build as the build has not been working since mid November.
You may be able to use the kernel update if you are on a fairly recent version or you could switch to the KANG MiRaGe ROM which does include the kernel fix together with other improvements which have not made it into a nightly. Look for the main MiRaGe thread in the development forum.
Other than that before applying this kernel fix people were using various techniques for switching wifi off rapidly when suspending which seemed to be a work-around.
I haven't had a SOD since using the new kernel when it first appeared and as now as embodied in MiRaGe.

I'm on cm7.1.0, I don't get SOD all the time just on occasion without pattern
-XDA Premium on CM7 Nook Color

Widgets...
Don't use Beautiful Widgets. That causes SoD's. Other widgets may cause the same problem.

I have found that every widget that has weather causes SOD for me. All others are okay.
Sent from my NexusHD2 using xda premium

I had to switch ROM's from MIUI to Phiremod to get this to stop. Works fine now even with Beautiful Weather Widget active.

The KANG ROM you describe is the one I have been on since it was introduced. I had the SOD fix but it still occured albeit infrequently. My "fix" is to just shut my Nook down every night. I haven't had one since.

Setting wifi to shut off when screen goes off also works for me (the issue seems to be wifi related). You can also use tasker to shut wifi off when the screen turns off.
Both beautiful widgets and the go weather widgets have caused the sleep of death for me. Without any widgets, my Nook would be up for weeks at a time.

Quick Tasker fix for SOD

Click to expand...

Certainly...
I'm assuming you have a basic understanding of how to use Tasker, if this is not so please let me know and I'll be more in-depth. I created a profile named WIFISLEEP with the condition being "Display Off". The first step of the internal task is to wait 5 minutes, with the "IF" box checked and the "IF" condition reading "%SCREEN ~ off". The second step is to set Wifi to off, with the same "IF" condition as the first step. The third step is to play a notification sound (not required, but nice to be assured that your profile actually executes), with the same "IF" condition as the first two steps. I already had a "Display On" profile (for setting the CPU governor and speed), so I just added the next part to the pre-existing profile. If you don't already have such profiles you can just create another profile (named something like "Display On"). The condition, of course, being "Display On", and the first task being "WiFi set On" with the "IF" condition being "%SCREEN ~ on". The second task being "WiFi Net Action Reconnect", with the same "IF" condition as the first task. Not only does this fix my SOD problems, but it will also save you quite a bit of battery when not in use for long periods of time. There will be a slight (10-20 sec.) delay waiting for the WiFi to reconnect after you turn the screen on (as long as it's been more than 5 min of course), but it's definitely worth it. The reason I have a 5 minute wait is so that downloads can finish before they are cut off, you can set the wait time longer if your downloading times take longer. Overall, this did the trick for me on SOD.
*EDIT* I did also get ahold of a much better WiFi management application called Green Power. Instead of having Tasker turn off the WiFi after 5 minutes of the screen being off no matter what, Green Power throws in a few more conditions to look for. Through Green Power I have it set to turn off the WiFi after 20sec of the screen being off IF WiFi traffic is at 1Kb or less. If it is not at 1Kb or less, the app will re-check the traffic every 10sec until it is at or below that level, then shut it off. Also, while the display is off, Green Power will re-enable the Wifi for 2min every 30min to allow data sync to occur. When the screen is turned on, WiFi will be re-enabled automatically. However, if the device can't successfully connect (after 30sec) OR if the strength at connection is less than 20% signal, the WiFi will be temporarily disabled so that there is no battery wasted continually trying to connect/stay connected. This setup is perfect for finishing a download after the screen goes off and then putting the WiFi to sleep, and quickly giving up on the reconnect if there is low/no signal and trying again later. This also fixes the SOD for me, with better overall management than what Tasker can provide as far as WiFi is concerned.

Hey guys, just wanted to post what I used to fix my problems related to SoD.
I was getting SoD all the time with any ROM that I used, no matter 7.1.0 or 7.2. So recently i started fresh on a 7.1.0 stable rom and moved the ROM from SD to EMMC, but the problems still persisted.
After seeing this thread, it gave me some insight regarding the root problem... For me, it seemed that wifi being on when the screen was off was the culprit. So I downloaded the free app called "Easy Battery Saver+ Task Killer" found here:
https://market.android.com/details?...SwxLG51bGwsImNvbS5lYXN5LmJhdHRlcnkuc2F2ZXIiXQ..
I set it to the "General Power Saving Mode" profile, which basically turns off the wifi whenever the screen is off.
That seems to have fixed the problem, now I never get a SoD! So I recommend giving it a try!

If you are interested in my opinion...

The problems I see here are that there is no WiFi traffic check (at least from what you've explained) before it kills the WiFi, and the Task Killer part. Task Killers actually cause more battery usage because the Android System will have to use more battery to re-start many of the killed processes. This is because the OS is programmed to keep some/most of those background processes running and will continually re-start them no matter how many times a task-killer stops them. It is better to have apps such as Ram Manager Pro (http://forum.xda-developers.com/showthread.php?t=1111145) or V6 SuperCharger script (http://forum.xda-developers.com/showthread.php?t=991276) to optimize your RAM for much better smoothness and crisp response, with much better battery savings. Combine one (or both depending on what parts you use for different activities) with Green Power app, which will give a hand-full of extra conditions to look for before turning off the WiFi at screen off and thus fixing your SOD and providing better performance with extra battery savings. I hope this helps!

ICS Roms Battery tips and tricks request

I thought it might be useful to start a thread dealing with any tips and tricks anyone might have found when using ICS Roms with the Kindle Fire. I know that the kernel is still a work-in-progress, so I know it will definitely get better over time. This info is likely spread across multiple threads, so hopefully we can consolidate a bit to make it easier for everyone to find.
What I'm hoping is that folks can list suggestions like CPU Frequency, CPU governors, apps, and other tweaks that everyone else might find useful. Thanks.

great idea
everyone should share their experience with cpu governors.cpu frequencies for better performance and battey..

Green Power app
I found one suggestion from user webdroidmt on the 3.0 Kernel forum suggesting using the app Green Power to manage WiFi sleep. I think a number of users have reported issues that WiFi doesn't actually seem to shutdown during device sleep, no matter what the policy is. The Green Power app can be set to do this. However, one issue i've noticed so far is that once I come back from sleep, my WiFi icon doesn't seem to reappear. This could easily just be user error and nothing wrong with the app, but I thought I'd mention it.

Actually, it appears that if you wait a bit on the lock screen after sleep, the WiFi icon will appear. If you just unlock right away, the icon is gone.

i use the batterybar app and plug/unplug the power lead until i see the bar moving to show charge.(animation needs activating in app)
i have never had a flat battery and i am always at ease that i know it is charging.
or aokp has a batt bar built into rom.
hope this helps in some small way and stops the *****ing in the

That *is* the SOD. It's not caused by an app so much as meeting those conditions. For a quick fix set wifi to turn off when the screen turns off. Search is your friend for more info/fixes.

Like MISRy said, it is not a specific app causing it. It is the fact that you leave wifi on with the screen off. And not just specifically screen off, but in deep sleep. But it is not consistent and not everyone gets it. Some of the devs could never make it happen. Usually it is when wifi is on with screen off and an app is using it that is the problem. So if wifi is on and being used, and at the moment you try to turn it on it is in deep sleep, bingo SOD. As I said in the other thread, look at my tips.

No, the kernel and wifi kernel module are two different things. The wifi kernel module has to be matched to the kernel (it is a kernel module), but is a separate piece of software. It is in /system/lib/modules/twlan_drv.ko. No SOD patches have been used in any stock CM7 kernels or modules. I think Mrg666 uses a patched kernel for his Mirage build and sometimes it is enough, but SOD does not really stop until the patched module is used.

Dear all my friends who facing the SOD Sleep of Death issue with their Android devices...
i found that it is totally related to Wifi Sleep policy related... i just changed the setting last night n now after 8 hours it is running absolutely without SOD... i will also be inform u later if i will get my device out of SOD issue... all of u just have to do one thing.
Go to settings>wifi settings>
from the options go to advanced settings
there is one option: Keep wi-fi on during sleep (go to this option)
there is 3 options: 1. Always, 2. Only when plugged in, 3. Never (increases data usage)
u just have to change ur option from 1 to 2 or 3, then i hope u will find that u will get ur device out of SOD issue...
