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?

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

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.

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!

Yeah ive been using the Advanced Task Killer for a while now already.
I have read that usage of ATK is not required at all because of Androids near perfect RAM Management. And you also could come into trouble because android looses a small amount of ram capacity every time you use ATK untill the next reboot.
other than that you could try Juice Plotter and Juice Defender
find a app can auto turn on/off fly mode.
I ve tried Juicy defender, it seems not fit wildfire very well, some function not working. like auto fly mode, and auto turn off wifi when over 50M.
(btw,it will change your apn setting,cause me can not connect after uninstall it.)
after 1 month, I found navigation app take me 80% of battery.like google map/navi.

Not sure if these steps actually improve the efficency of the battery OR wheter the S/W behind the battery guage becomes more accurate as it goes through a process that alows it to better estimate the SOC of the battery.

Yup, even I have read a lot that Android manages the apps in a beautiful way. When I first used Android, the first question that came to my mind was how to exit apps as none of the apps had an exit button. Coming from nokia, sony erricson etc this was an obvious question to ask. Then after some research I found that Android just freezes the apps when we go back. The app is not actually running in the back end.
But anyway, yesterday my battery again went to 8% and on checking the used status, it showed that the android system used 92% of the battery lol.
One more thing I would like to suggest is that there is a Power control widget built in the wildfire. Its pretty useful to decrease the brightness, turn off gps, wifi etc from the home screen itself.

Thanks for this!
I installed this widget and it said that GPS was on even though it wasn't appearing in the tool bar along the top. I had run several apps that use GPS, but had assumed if the GPS icon was gone, GPS was off.
Is that wrong?
(good news if it is, as I was struggling to keep enough power to in my phone to get through the day without charging)

Avoid task killers like the plague. They cause more problems than they solve. Trust the android os to manage ram.
Just discovered the most powerful app I have ever seen called "Tasker". It its only £4, but will make your android so much more diverse. You can, for example, have it go into airplane mode between certain times (i have between midnight and 6am) but periodically check for sms or voice mail every hour. It saves stacks of battery.
I have it turning wifi on only when it knows I'm at home or at work.
I have it turning off wifi, dropping screen brightness down, and playing a louder notification when battery gets to 15%.
It silences my phone when I get within 100m of the two cinemas I use.
It is not the most easy app to use, be patient with it. Look up some of the "recipes" on the internet to get a good tutorial on how to work it. £4 is a steal for something so potentially vast. Its limited only by your imagination.
Oh and having run Tasker for 24 hours, (how long my battery normally lasts) only contributes to a 2% drain, and its adding roughly 6 to 8 hours extra! It would cost you ten times that for an extended battery!
I use an free app called timeriffic to auto disable WiFi

Try program JuiceDefender....you can download free from Android market.
my battery life is really awful too,i noticed it a couple days ago,that it drains to fast,so i started looking into it,and i found out,that my device won't go too sleep. so in settings/about phone/battery the awake time and up time are the same. i had similar problems on my hero, but there it was the messaging apps fault.
here, i kill everything with advanced task killer,it still can't go too sleep,android battery use shows,that android system is using most of the battery.
anybody else with similar problem?solutions? i have stock 1.25 rom rooted with unrevoked.
What? You mean your screen is permanently on? .....
Ive head bad things about using task killers too, I dont use on anymore.
Some things i have done that have helped my battery like quit alot actually is turn off Wi-Fi, Turm off GPS, Turned off haptic feedback(vibration when pressing buttons), Screen brightness to automatic & screen timeout too 15 seconds.
I can now have a really good fiddle with the phone and it can last more than a day without needing a charge.
As I understand when screen goes auto shut off, all apps are idle, even WiFi or gps is on. I tried with music on continuously for 2 hrs in flight mode, I still have about 80% power. With gps on for 1 hr continuous, I still have about 80%. With normal use my power can last the whole day.

no,the screen turns off,but something still runs in the background what eats the battery,and I can't find out what it is. I tried multiple task managers,and they show that everything is closed.i have it in flight mode,with everything turned off,still something runs,what shouldn't.
Did you solve this? It's happening on my phone now, and it's very frustrating.
(just installed ATK - very scary the apps I never use are running) and killed everything except ATK. Touch the power switch to turn off the screen. 15 minutes later, up time and awake time are still the same.

2 updates from me, to help anyone else with similar problems:
1) I uninstalled any recently installed or updated apps** and widgets now I have a 1:6 ratio of awake time. So, fixed?
2) In the meantime I logged a call to HTC via their website. Answer:
With regards to your problem, if the battery is going down significantly and you have turned of applications when your not using them and used task killer. It might be better to call us up so we cann look into it further and we might have to book the phone in for repair especially if you have noticed it not charging properly or overheating at any time.

I really wonder why there is none of such thread here!
Gingerbread unfortunately brought only bad things to my Nexus. I already forgot why I was so crazy about installing it.
What feature did it introduce again?
Okay the response is much better and everything seems faster...but with lots of bugs?
That screen off animation? Seriously?
Things that I hate now:
- Battery Time: this is bad, can't even run half a day with lot of usage, b
efore I could listen to mp3's one day, ie. more than 4 hours without any problems...now
- Camera: either Cam or Video, the application crashes after I take a photo or video and then I can not connect to it anymore
- Gallery: often crashes, especially if you have an online photo account connected
- unlock screen: I use a pattern, often there is no overlay of what pattern I drag, still the screen can be unlocked
- Market: even if automatic updates activated, it only updates if you open the market and go to the "my apps" tab
- 3G and Wifi: if you are connected to wifi more than 15 minutes and then disconnect from it you do not get any 3G, you have to go to airplane mode and back, this bug appeared ages ago and was fixed, now back again...tells you a lot about their merging control, ie. sucks
- notification led: you know...
- apps: there are a lot of apps running even though I never used them since restart (see it in a task killer app)
- gps: on a random bases it tries to lock even though no app that uses gps is running
- phone reboot: it even rebooted without any notice two times since I installed it
(- Contacts: I still can't enter a simple thing like a birthday on an expensive phone like this)
MOD EDIT: Borderline trolling removed. If you switch OSes, that's your own choice. No one here is stopping you.
Got any troubles? Tell here.

As far as battery goes, my display is still the thing that takes up the most battery (which is normal) but I had been experiencing severe declines in battery life. Does the switch to 32-bit color require more processing power and therefore battery?
I *#*#4636#*#*>phone information and saw it was set to WCDMA preferred. I remember playing with the option when froyo came out but didn't remember what it was set to (Maybe Gingerbread reset the option...?). I changed it to GSM PRL (Auto), and have experienced increases in battery life, as my phone isn't hunting for 3G all the time- it uses a service provided list of tower locations.
The LED REALLY bugs me.

-Battery with CM7 roms
-Trackball wake blocked in non-CM7 roms
-More difficult to mod themes like statusbar (before we just had to change a png and now we have to edit a bunch of files)
So in summary GB roms are still not stable and complete, they have either TB wake missing or poor battery life too
My annoying issues?
- 2 second mic mute after I answer a call
- stock launcher choking after a while
Less annoying ones:
- Market does not automatically update apps
- gps activations without an apparent reason
My annoyances
In no particular order:
The cursor select triangle not lining up with the cursor
Launcher unresponsive/vanishing
Lockscreen pattern not showing (as in the OP)
Phone randomly stays awake at night
GPS turns itself off
Not able to view an apps wakelock any more
USB mount screen shows 'turn off' even when it isn't mounted (UK issue)
USB debugging icon doesn't appear, or doesn't turn off depending on how you enabled it
Exchange push is just crap now, I swear it's getting worse by the day

While I'm not a big Gingerbread lover at all, here are answers to some of the points:
Battery time is fine, at least in freshly installed ROMs it far exceeds what Froyo mastered.
Camera is your own problem - you didn't update radio, or your update went bad.
Gallery never crashed - again, your own problem (you get the feeling now, right?).
3G and WiFi - again, your own problem. No bug.
Apps - and why do you care? Isn't the "DO NOT USE TASK KILLER" thread clear enough? 150-200MB free RAM aren't self-explanatory?
Due to your comments, you might really consider switching to Apple. It would be beneficial both for you and for this forum.
Or you could back up user data, wipe, install new radio and bootloader, load fresh Gingerbread ROM (NOT CM7 or CM7-based), and have most of your points addressed.
Now, having said that, if you want a much better overall feel - install Froyo-based Desire port, or if you don't have any use for Hotspot - DesireHD port. I hate using barebone Android after some experience with it.
have you guys heard about Cyanogenmod ROM? I am using CM7 RC4 and I have no problems that anyone mentioned in this thread....
Maybe you haven't heard that your experience not necessarily represents anything.
For me (and another 2 guys that asked me to reinstall other ROM on their Nexus Ones), CM7 was a huge, awful pile of bugs. Starting with the ill-famous "wonk".
Plus, again, after having some SenseUI I don't really want to go back to plain Android, and wouldn't suggest it to anyone looking for a good overall experience.
I have an occasional problem with the application tray where it stutters, flashes and doesn't scroll properly. It seems to happen only after exiting certain apps, and needs the launcher to be force closed to fix.

Just lost all credibility in my book...
I would suggest the OP decides what features he/she wants in a ROM and then try a few different ones out. There are plenty to cater to all tastes and i'm sure they'll be able to find one that works well for them.
1. exchange sync stops syncing without any reason. can't start a manual sync. only reboot of the phone helps for a short period of time. needs a fix very urgently.
2. TINY TINY notification icons...the worst idea google had for the GB update. i cannot see the difference between the gmail and exchange mail icon on normal usage in example.

QFT!!!!!!!!!!!!
Auto brightness adjustment no longer fades, now it just jump straight to the target brightness which is quite abrupt visually.
And of course... trackball wake is gone.
I concur with these points:
- Battery Time: this is bad, can't even run half a day
- Gallery: often crashes, especially if you have an online photo account connected
- Market: even if automatic updates activated, it only updates if you open the market and go to the "my apps" tab
- GPS: on a random bases it tries to lock even though no app that uses gps is running
- Creating shortcuts on desktop: sometimes you can't drag/drop icons to the desktop or to a different spot on the desktop.
- The cursor select triangle not lining up with the cursor
- Auto brightness adjustment no longer fades, now it just jump straight to full bright or full dim.
As for the people suggesting we update the radio and try different roms, while that is primarily what this board is about, it doesn't "solve" anything. This is a stock Nexus One with official everything. If it doesn't work then it doesn't work.
I've been trying loads of things to try to make things speed up a bit more with my rooted Bell Atrix running the new Telstra FW, and the 4 things I've found that seem to improve the UI speed that do not require rooting, are as follows:
1. On a fresh reset, use the Atrix to format both internal and external SD cards. For some reason after doing this on a fresh reset, it seemed to speed up the "instant on" when the phone is asleep and you press the fingerprint scanner on/off button to wake the phone. Of course, remember to back up your external SD to your PC prior to doing this.
2. Setting the Wifi to be always on (never sleep when its on).
3. Don't use ATK task killer
4. Don't use SetCPU
Even with all my apps reloaded, and loads of use over the last few days, I found these things to cut the usual 3-5 second wake time to between 1-2 seconds, and for some reason the general UI speed was much better (even using Blur)
I'd be interested to hear any feedback on people who are thinking about starting fresh and resetting their Atrix, and trying the above to compare to what they had.
I'm rocking the telstra with all the blur and bloat deleted not frozen. I deleted the browser because it doesn't let me download apps from the internet. I replaced it with dolphin browser. Deleted email and various other apps like car dock, etc. I underclock to 800 for screen off. I literally replaced every transition animation with an app from jrummy (root required) I use automemkiller to allow more memory for empty apps and honestly I have a lwp running and constant usage and I last 16 hours on a charge and use it constantly! Death to all lag.

If you are around Wifi more than not, it is best to keep this on "Never"... The Wifi uses way less battery than 3G/4G. Having your phone update using wifi will save battery for sure.

You must have one special Atrix . The only time mine wakes within 1 second, is within 10-20 seconds of the screen going blank. If its been sleeping for more than 1 minute, it takes at least 3 seconds to wake.
I starting a bounty for fixing the android os bug.
Anyone that fixes this bug gets the bounty. (not samsung or google tho)

Keep the discussions in the other threads.
But maps is not the cause.
Switch Wifi sleep policy to "never sleep"
From the page for this issue on Google Code (others have linked to this page already but apparently no one here has bothered to actually read it):
code.google.com/p/android/issues/detail?id=15057
There appear to be two main causes of extreme battery consumption by the Android OS process.
#1 is the Wifi sleep policy of "wifi off when screen off", which is usually the default. If you haven't made a point of changing yours, it's probably still on this setting. In the Wifi settings page (where the SSID list is), press menu, then advanced, then Wifi sleep policy. Change it to "Never". A more blunt-force solution is to keep Wifi switched off all the time.
#2 is some combination of Google Latitude and location services (GPS and Wifi). This one seems to be less common and many people say it's definitely not the problem. It may be related to #1 in that a problem with the Wifi is causing location requests to fail, somehow causing extra processing.
Comment 23:
The increased consumption only occurs, when I have the wifi sleep policy set to "sleep while display is off". In this case the battery consumption is very high while the display is off.
Comment 31:
Only changing Wi-Fi sleep policy to Never from "Never when plugged in" fixed this for me for now.
Comment 40:
I can confirm that "Always on" WiFi policy solves the problem for me
Comment 53:
By putting "always on" to the wifi sleep policy, I'm now at 25% battery after 1 day 7 hours of usage (since last charge)
Comment 54:
The recommendation of changing the wifi sleep setting to 'Never' appears to have worked for me as well.
Comment 88:
Both "always on wifi" as well as "turning wifi off manually" work for me. The heavy battery drain only occurs in combination with the "wifi sleep while screen is off" policy.
Comment 90:
I have 'never sleep' policy for WiFi, and battery life is just fine.
Phone easily can sustain a day with some 40% battery remaining.

A poll to see whether these solutions work for everyone would be good. I probably can't make it because I just registered.

These fixes wont cure it for sgs 2.
See attached. It's not the wifi policy.
I too will pledge $30 for a working fix once I've verified that the problem is solved.

Nice, i will update 1st post with all the findings so far.
"android os" bug is NOT:
Wifi bug (always on)
Maps bug
Any installed apps bug
Operator bug
Latitude bug
count me in with $30 as well

I had similar issue on SGS, my problem was because aparently I got a faulty modem file, I noticed my signal bar going up and down continously.
Has anyone tried changing modem?? I don't have a SGS2 so I don't really know if there are modems to choose from...
Good Luck Doc.

Getting a good idea now, a first setup on 3g network (no wifi), avoid the dir 655 routers and you be fine.
Wifi policy is set to "never" by default, so I can't see why it would help anyway.
That said with KE1 and a factory reset, although I have higher than would usually be expected AOS usage, my battery drain issue hasn't been all that bad - from a full charge today (7hr 15 on battery) to 83% with maybe 20 minutes angry birds, and the occasional checking of emails, texts and facebook and playing around with it a bit...
Screen on time 31 minutes... Android OS at 20% now and Wifi Sharing(!?) on 13%.
So not too bad, but it could be better IMHO - equates to about one and a half days of light use - definitely room for improvement.
There are so many threads about battery so not sure which one I should post it but..
I saw some strange things in Logcat. I get alot of those errors :
E/lights ( 2701): write_int: path /sys/class/backlight/pwm-backlight/brightness, value 170
E/lights ( 2701): write_int: path /sys/class/leds/blue/brightness, value 0
I don't exactly know what the error means(well they are related to the menu and return backlight I think), but the E/ stands for error in case you didn't knew.
Do you guys get the same kind of errors in logcat?
I've noticed 2 things:
If I wake it up, the cpu frequency doesn't go below 800mHz. (with only 4% load)
Only after I've started an app (not a widget etc.) it went down to 200.
(look at the "Temp+CPU V2" widget on the screenshot)
And the camera seems to run further if you don't go back out.
After a shot in school, I pressed the power button and at home, it felt VERY hot (front and back) and the battery level went down in 3% steps every 1-2 minutes.
But the camera wasn't listed in the battery stats, only Android OS, which was eating 70%.

Android OS Battery bug
Hi!
1. Install SystemPanelLite Task Manager from the market.
2. Run SystemPanel and open settings and check the "System processes" option. Close settings.
3. Scroll down in the process list until you find the process "android.process.media". If you have a CPU usage of more then 10-30s and the process usage gauge to the left moves up and down you probably have the Android OS battery bug.
At this point you can try the following;
- Shut down your phone. (Not just turn it of. The complete shut-down-power-off-thingy)
- Remove your external SD card.
- Start up your phone again.
- When the scan media is complete, do step 3 above again. If you don't see the problem at step 3 your SD card has a corrupt filesystem. And needs to be reformated. Follow these steps;
- Backup your data first!!!
- Settings -> SD card & phone storage
- Unmount SD card
- Format SD card
- Restore files from your backup.
If the problem persists your internal SD card might have a corrupt filesystem and needs to be reformated. Follow these steps;
- Backup your data first!!!
- Settings -> SD card & phone storage
- Format internal storage
- Restore files from your backup.
More details; What happens when you have a corrupt filesystem is that android.process.media tries to read a file but fails over and over again. The filesystem might not look corrupt to you. And you can read and write files on the SD card without problems. But at some point the android.process.media failes to read the files and loops like crazy, draining your battery.
I had a corrupt filesystem (FAT32) on my external SD card. I also had Android OS battery usage of 60-70% and a fast draining battery. I hope this can help others.
Best regards,
/Pontus
My android.process.media is 27 secs. Is this in the acceptable range?
Hi!
It's a bit high I'd say. I've got like 2000+ photos and I'm at 9 s after a days use.
Take a look here;
Settings -> Applications -> Battery usage
If Android OS is above 50% then you should consider my suggestions.
Most importans, does your phone get hot and use a lot of battery without heavy use?
Removing your external SD card and rebooting your device isn't that much work. If that gets rid of your problems, then reformat your SD card.
FAT32 isn't the most robust filesystem.
Best regards,
/Pontus
how can i remove the languages which i dont need?
what's causing the battery drain inside Android OS
After doing further investigations with watchdog, the Android OS battery drain is caused in stand-by by:
1. suspend (linux process)
2. events/0 (linux process)
They use heavily the processor while in standby... I've seen alert of up to 80% of CPU in both processes.
I updated to CM 7.1 RC1 last week and I've noticed a few times where the device has locked up after "going to sleep". Essentially, if I leave it on the coffee table with WiFi on and let the screen turn itself off, it won't respond when I return to it 20-30 minutes later. I have to force reboot via the power button + nook button.
Just curious if anyone else has noticed it or if it's just me. If it's a common issue I'll escalate to the CM folks, if it looks like just me I'll start the long and tedious process of uninstalling apps one by one. =)
I have at least one every day. I figure its just a price I pay. Over all its the best rom I have used.

Only once have I had the issue you described. I leave WiFi on some of the times, but majority of the time I have it off when I am done using it. I know some people have mentioned using Tasker or something similar to turn WiFi off when screen goes off so that it can perhaps be prevented.
EDIT: I don't believe I can link yet on my account, but search General for the post "NC, CM7, Dalingrin OC kernel.. Sleep of Death" and start about post #6.
Thanks bio, that looks like the exact issue I'm experiencing.

That's a pretty generic statement... what did you blacklist within Droid wall to increase battery life / fix the issue?
I'm facing random freezes when I open an application like tweetdeck or mercury and leave it updating from the internet. After some time, I'm not using it, it just stucks. To get it back to life I have to press for a few seconds the power button to shutdown it and then again to power it on. I have used different nightlies, voltages or governors but it is still here.
Now, I don't have freezes since yesterday that I really reduced the voltages but I'm not sure if my problem is solved.
configuration: 144 nightly 300-1100mhz xlv profile
not sure if anyone has told you that what you describes is called:
Sleep of death.
Felt to be possibly related to wifi being on all the time. In wifi settings, go to advanced change it wifi to off when screen off.

I'm sorry. I use the white list feature and only check mark the current application that I want to use and allow to access the internet. It keeps everything else from using background data.
For example right now I selected xda and updated rules.

It seems that I solved it reducing the voltages. When sod occurs a black screen appears right? I never had sod, only random freezes.
