l2_hsic wakeups - finally getting rid of it - Galaxy S II General

i posted this in the Note section since it had a big thread going about this wakeup annoyance called l2_hsic, but as i am using a S2 i should post this here as well (you may remove my posts there if you think 1 is enough, i have no permission to do that yet), its a wall of text so im just gonna quote it:
i too had alot of battery drain without actaully using the phone much, was reaching aorund 2 weeks on stock 4.0.3 but the performance wasnt all that, so i installed Supernexus & DorimanX (extreme_battery), great performance but the battery wasnt really what i expected, barely a week with low usage, tried lots of things while i searched a ton of topics about l2_hsic, using gsm-only with FD disabled, turned off play store notifications in the store itself and market updates in TB, WiFi is only on when needed, data usage is disabled, so is gps since i dont use it, baseband/ril is matching, and disabled stuff in TB/gemini/LBE which i dont use, battery got a tiny bit better but far from the 2 weeks i was reaching with stock (had alot of stuff/bloatware frozen though), i was even thinking about flashing stock again but that was gonna be the last option, performance on custom roms was far better
so it got me thinking, saw alot of l2_hsic wakeups with no appearant reason to why or what was triggering those while i had just under 1%/h drain with all that stuff off, then i remembered the last time i opened the play store before flashing Supernexus & dorimanx it didnt work, probably froze too much in TB but didnt want to get to the bottom of it since i was gonna flash a new rom & kernel anyway
so a couple days back i decided to freeze google play store/services and market feedback agent in TB and block them as wel in gemini (had a hunch they could be the culprit triggering all these wakeups since some autorun lines automatically re-enabled themself after turning them off in gemini, one even was called WAKE_UP lol), denied all access in LBE and then used the phone as i normally would (occasional WiFi, couple calls a day and thats it)
rebooted the phone a couple times the last couple days to test if it wasnt a 1-time-wonder but things stuck and im glad to say im now at 0.2%/h of battery drain in deep sleep, up to a max of 0.5%/h when in use, down from around 1%/h in deep sleep, so it will probably last a bit longer than the stock rom/kernel would have before, great success!
before i froze the store/services/agent i had around 1500 wake counts from l2_hsic on a couple of hours while the phone was in deep sleep, now im at a couple wake counts on almost a day while actually using the phone like i usually do
now, in case i need to go in the store i just have to enable the stuff again in TB/gemini/LBE, little effort imo for alot more battery life

notice the l2_hsic wakecounts are now 16 on a week, where i had a couple thousand during a few hours of deep sleep before i disabled the store/services/agent, this is the stock battery with Supernexus + DorimanX (extreme_battery) on 2G, wi-fi wasnt on this week, and i only make like a couple short calls a day, same as ive always done, yet the store woke my phone up so much i barely reached a week with a full battery before disabling it

TLDR: in a nutshell, after trying all possible solutions to get rid of the thousands of l2_hsic wakeups (in deep sleep that was), it was actually the google play store/services(/agent) that caused it, disabled it, and i have more than doubled my battery life
obviously most people use their phone alot more than me, i make a couple calls a day, rarely turn on wifi and thats it, someone using the store on a daily basis is probably not gonna disable it and reenable it over and over, just wanted to point out how much the store actually drains your phone without wifi/data in deep sleep on a 2G network

It's a pity that gmail/youtube wouldn't work at all after disabling google play services, google play store and market feedback agent.
The data/wifi signal that would usually turn blue stays grayed out. I'll be trying enabling just play services

Interesting, it would be good to see this bug fixed but Google apps remain connected, especially Gmail

and after a couple months the l2_hsic evil is back for no appearant reason, i hit up TB one day with half a battery and it couldnt find the pro key again, so i closed it and thought i'd ignore it, next day i turn the phone on again and my battey is near empty, wtf? enabled google play stuff again, updated my apps including TB, pro key problems solved, disabled the google play stuff again, no luck, l2_hsic is back in full force, disabled all the google apps, no luck again either, but i noticed umts_ipc0 was in there too with just under the amount of l_hsic wakeups, which has something to do with the usb, so i started looking further and it seems a fix for the l2_hsic wakeup bug has already been found, even though its on another device:
http://forum.xda-developers.com/showthread.php?p=41338478
only problem now is to have the kernel modders take a look in their kernel and see if that bug is present and if so, if they can fix it?

Use non stock battery? Salutes for 7 days for 35% remaining even standby on 2G..:what:
Sent from my GT-I9100 using xda app-developers app

using stock battery, the better ones havent been available in my country for as long as i can remember, would have bought one if they were
shame i cant get that battery life back from my OP, it was 35% used instead of remaining after 7 days with the l2_hsic going mental again now im lucky to even hit 7 days with a full battery

Solution to battery life issues (works 100%, guaranteed)

I love this phone and have posted this on several forums already. I want everyone to enjoy it as much as I do.
I switched from an IPhone 4 to the Atrix and I am really impressed by the device. HOWEVER, I was very close to return the phone due to poor battery life (in comparison the IPhone 4). The max I got out of the device was 14-16 hrs and the strange thing was that it did not make ANY difference whether I hardly used the phone at all or played around most of the time. Over the weekend I checked and after unplugging the phone from the charger and leaving it on the desk the battery was down to 70%.
By the end of the day on my IPhone I used to have about 30% battery left with all radios (3g, bluetooth, wifi, GPS) on and moderate use. With similar use and GPS off the Atrix hardly made it through the day. I read several suggestions and wanted to share how I increased battery life by almost 100%!! Like mentioned earlier I was puzzled that even in idle status there was a 10-15% drain. The only logic explanation was that there are services that continue in the background and drain the battery.
1. I think the absolute biggest battery drain is to enable wifi triangulation for location services. The fact that the pop-up window states "...Collection will occur even when no applications are running." should have made my suspicious. I have noticed that enabling the GPS does not have any significant effect on battery life as long as you do not have any applications open that use that radio (like maps). Obviously I disable the wifi option in location services.
2. Root your phone and download Titanium Backup PRO. Disable all Motoblur services. I do not use any Motoblur widget/services (no facebook, twitter and so on) and am happy with the native gmail client. I literally froze allmost all of the motoblur services as well as other services that may use data services in the background (news, weather services).
Following link gives a good overviw which services can be disabled without any problems:
Death-Force • Thema anzeigen - [TIP][Tutorial] Freeze Motoblur for more Performance and RAM
3. I haven't really found it helpful to use setcpu. Whats the point of having a ferrari and driving it at 30 mph?
Since making those changes I have seen a significant increase in battery life. Using the gmail client, bluetooth+GPS+wifi+3g on, screen set to auto-brightness and mdoerate use throughout the day I make it easily throughout the day with the battery indicator showing in general 30-40%. I think step 1 made the biggest difference. Again, this phone is just amazing and I do not miss my IPhone at all!
No way!?!?

Because you don't want your Ferrari to use up gas while you're not driving it?
With SetCPU, you can set a profile for it to throttle down several hundred mhz whenever the display turns off. I find that even background services like Pandora can run perfectly fine even when that dualcore "ferrari" of a machine has the display off at half the ghz.
Using setCPU alone, I feel like me battery life doubled. I recently froze motoblur in its tracks and only provided minimal increase compared to just underclocking it.

my trolling = quotes and screen shots of Dumb and Dumber.
its amazing how experiences vary from user to user. i had installed setcpu the 2nd day that i had the atrix and didnt really notice a big improvement (with it properly set up to save battery). i froze the blur settings and the weather widgets and can easily get through a heavy days usage. i find the atrix is at least as good, if not better when it comes to battery life.
i leave the wifi and cellular location option on and my battery life is great. i dont have widgets or apps running in the background that need my location and i even say no when google asks for permission to use my location for better search results. disabling this feature would make a big difference for people that use location aware apps often but i find it takes far too long to get a good gps lock when using maps if this feature is off.
as long as you are happy with your battery life, thats all that matters
Never used setCpu on my phone. battery lasts for awhileeeeeeeeeeeeeee!
setcpu is not necessary the cpu automatically throttles down when not in use, the phone doesnt run at 1ghz all time...
ive noticed with the atrix you need to turn off gps when you are not using it or it will still be on even when no apps are using it. my captivate used to turn off gps when i exited an app that was using it. im not sure if this is the case with wifi too.
After playing a long time with phone I found synchronized apps like talk, gmail, take up most of the battery.

Stock Android 4.3 'Android OS' permanent wakelock

Looking at some XDA and Reddit posts, small set of users (my Nexus 4 including, unfortunately) experiencing some sort of bug with stock not rooted Android 4.3 after OTA on all range of Nexus devices.
The bug is Android OS holding device awake all the time and not letting it into deep sleep. It looks like it has not huge impact on battery life, but still it is abnormal. Rebooting devices, for me, curing this, but only for a day or two, after a few days wakelock makes its come back.
Unfortunately WakeLock Detector does not show who is guilty, looks like it is in the kernel. I just have bought BetterBatteryStats, and will look at its data tomorrow. What WLD does show is that my Nexus 4 had 0:00 of deep sleep today:

Here is what Android's battary stats looks like:
And here is what is should look like and does look like on my 2012 Nexus 7, that is unaffected by this. And stats looks the same for a few days after I reboot my Nexus 4, before wakelock occurs again:
I have to assume that it has nothing to do with connectivity, because same thing happens even if I disable wifi and mobile data entirely.
Here is a list of topics about the same issue I could found, but they only have questions, not answers.

Unfortunately, I also do not have any answers (yet). The purpose of this post is gather all the info I've found in one place, and maybe rise the awareness about this.
Update:
Ok. I had BetterBatteryStats on my phone for 30 minutes, and this whole 30 minutes PowerManagerService held wakelock itself. So, it safe to assume that it is an offender.
Hi, I saw your reply on this thread.
I read some speculation somewhere that the wakelocks might be caused by the device continually trying to poll for location, and apparently this behaviour could be corrected by the latest version of Google Play Services v3.2.25. I don't see the wakelocks now after upgrading to it earlier today, however this could also be because I rebooted my phone... Nevertheless I'm still not getting great screen-on time, just about 3.5 hours compared to other people's 5+ hours.
What's your version of the app? If you don't have 3.2.25 you can either download it directly (Android Police has put up a copy of the apk, but it might not be a Nexus 4-specific one) or download a more recent version of Play Store and wait for it to update Google Play Services automatically.
I'll report back here if I notice any more changes in my phone.

Location related wakelock are reflected in Android System and Google Services in the Android's battery stats, and as NLP (and some others) in the BetterBatteryStats. They account for about 1 hour of awake in a day. And they actually DO something.
This wakelock unfortunately does not show in Partial Wakelocks statistics in BetterBatteryStats, so I think it occurs somewhere deep in kernel.
If you use Google Now, or some other location based apps like Aviate, 3.5 hours of screen time is great. I do not turn off Wi-Fi, even when it is not available, use Google Now (without location history). 3 hours of screen on is what I expecting as a best case scenario.
Unfortunately, at days then 'Android OS' wakelock happens it nowhere near 3 hours.
So you're saying that location polling only affects "Android System" and "Google Services" wakelocks. Ok, I didn't know that.
But I did note that my "Android OS" wakelocks have now stopped. Although I cannot say whether the update to Google Play Services / Google Play Store had anything to do with it, or whether it was simply because I rebooted my phone. Do you know for sure that Play Services has no effect in this respect?
And yes, I do use Google Now and also Field Trip.
In any case, I'm also noticing that my battery drains at a much faster rate (as compared to 4.2.2) when I have my phone turned on.

It'll help with Google Services drain, I think. Anyway Google Play Services just updated for me (with Android Device Manager), hope it'll fix Android OS drain too. Hope is not high, though )
I've recently have this issue as well with "Android OS". Luckily I can still make it through the day easily but annoyed this kind of stuff still happens. I got the latest Google Play Services yesterday and still have this issue today after a full charge. Will reboot and see what happens I guess.

It looks relevant indeed. Although, I would not call the drain "rapid". I'm now looking close to my device statistics and try to pinpoint exact moment this lock occurs to find the cause.
If it is indeed caused by concurrent condition in PowerManagerService there is not much to do, but flash another, patched, ROM. But I eager to stay on stock.
Also seeing this with my Nexus 4. Reboot doesn't do much at all for me.
I was having the same problem with Android OS keeping my nexus 4 awake. It turns out the problem was using a wireless charger. If I wirelessly charged overnight my phone would never go into deep sleep when I took it off the charger. I went back to using the usb charger and the problem has gone away. I don't know if you are wirelessly charging but it did the trick for me.

It's documented problem about wireless charger https://productforums.google.com/forum/#!msg/mobile/c4HRzEUNmFk/geRlvQRtSPoJ
Looks like it was there since 4.2.2 and nobody cared to patch this in 4.3.
Unfortunately, it has nothing to do with my case. I do not own a wireless charger and the name of the wake lock is different. When it is related to charger it is PowerManagerService.WirelessChargerDetector keeps device from sleep. In my case it is less specific PowerManagerService.Wakelocks
I have this issue i think maybe going back to 4.2.2
I have the same problem of android os keeping phone awake on my nexus 4 .. I cant go back to 4.2.2 coz i face notification delay prob on 4.2.2 so i am stuck up with battery drain on 4.3 .. all os updates seem to have some or the other bug! really annoyed ... maybe i should have sticked to my htc one x+ .. atleast it dint hav any probs as such

I have been having the same issue . I finally dealt with it last night after flashing multiple ROMs and kernels. I went back to OTA 4.3/rooted/twrp and flashed from the updated .84 modem back to the previous .48 modem. Went back to only losing ~4% overnight. The problem appears to be the qualcomm modem driver. Additionally, I am mostly seeing this problem from people outside the US.

What I also tried, that didn't work at all, was stopping all running services during an Android OS wakelock. Even with all the services stopped and the RAM cleared, the wakelock didn't stop at all. So, it means the drain comes directly from the OS/drivers/etc, not any running app. In fact, after 2 factory resets, 1 reflash and keeping my phone completely stock for days, the Android OS wakelock kept occurring. Even if you don't sign-in into your Google account, the wakelock will still be there eventually draining all your battery.
I will have to give the old modem a shot.
So, somewhere here, on XDA, I read suggestion to clear cache (Settings -> Storage -> Tap on 'Cache' and then 'Yes') and then reboot.
I did this on Friday and to date wakelock did not return. I do not know did this really help. May be it was just a coincidence, or maybe this nasty wakelock will return, but this procedure is easy and harmless, so maybe it is worth to give it a shot.
Same Problem
I just got my nexus 4 a week ago and I have been having this problem ever since I got it. It seems to be an issue for me no matter what rom/kernel/radio I flash. I've also tried complete factory image flashes of 4.2.2 and 4.3 with radio and it has no effect on this issue. I am very discouraged because I love this phone other than that problem.

Nothing else on the forums worked for me so as a last chance, i tried this solution and it worked. Well, sort of. I did this last friday and afterwards android OS battery usage dropped from around 25% to 8%. Also in Wakelock Detector, i saw that my CPU was no longer awake all the time. But unfortunately, as of this morning, problem reappeared. I tried to erase cache again but it didn't work.
Is this happened to you as well?

If you can't find the source of the drain try a factory reset.
We went through so many threads like that, my man.
Do a search.
For the headup, assuming that you have already turned off Android location access, turned off Google location access, turned off auto-sync (I know you said you needed it but just for now, off it), turned off gps/mobile networks, do the following
a. disable Knock On/Off feature
b. disable CIQ (if you don't have CIQ, then ignore this step)
Note: do one by one and make an observation how the battery life behaves after each change.
Oh, btw, reboot the phone, say, right after unplugging the charge.

yup done all of that ! still same result ! even turned off fast dormancy as my network provider doesnt support it ! im not a noob to simply open up a thread in the q and a section. i might be new to this phone, im not new to android. anyways is your android OS staying awake ?

In term of battery life, I was considering myself as one of the unlucky one but after done all those, I got pretty good result. Normally last about 3 days with 6 hrs screen-on time and 4 hrs talk time. No wakelocks

you should know better than to give stats.... standby hours and battery life is varied alot by user, ambient temperature and etc.
OP if you feel thats not right, flash another rom see if it help, I'm using energy rom, its good for me so far.
Try remove some bloat and apk with titanium... A regular user can often remove 100 apk from these roms! And use bootmanager and greenify! Greenify is must have!

I know, but if you are the same as me, you will NEVER be 100% happy with your phone before you root it and do you own tweaking.

Don't hope, fix now.
If I was you, I would backup all my important personal info on the phone and factory reset it.
I would do those tricks one by one w/o installing any app yet and see how the battery fares after each charge.
General speaking, we need to understand the root cause and find the solution from there, if it needs to be rooted to fix the problem then you root it otherwise, blindly rooting and assuming everything else will fix isn't the right way to debug.

fact reset done , only whatsapp installed. same issue so i installed my other apps as well. im guessing its a kernel issue

N910F, "Android OS" battery drain - can't determine the cause

This started happening about a week ago... I didn't install any new apps in particular. I've attached screenshots to the post.
Screen-on time is a little below an hour in these screenshots.
As you can see Android OS and Android System are at the top of the list by a long shot. Android System seems "normal" in the sense that it has 58mn of CPU time and only 18mn of wakelocks (as reported by the built-in battery menu).
Android OS however kept the phone awake for 6h11 which seems like a lot. I'm not rooted, so I did the ADB USB trick in order to pull stats out of Wakelock Detector, and all of the apps clearly don't add up to six hours. Especially not the usual suspects like Google Services, Facebook, etc.
Diagnosis shows a LOT of system processes, and I'm not sure if that means 1) it's all good as far as user land goes (I don't have any weird apps) 2) there's a system process gone rogue for some reason 3) the cause isn't showing up 4) something else???
Does anyone have any idea what's going on?
I have the same issue. Tried greenifying everything. No dice. I reboot, phone fine, then stays away. I will say that my battery life is good though, but this riddle is driving me nuts
Here is my issue, look at away bar.

Me too - 910F - im on Lollipop, but struggling to make it through a day at the moment.
Checking my Battery Graph is the same Story - my phone seems to be Awake constantly.
Seems Android System is using it....
Anyone have any ideas?
I can only recommend rooting your phones and change roms or kernels.
TW is heavy on battery and if you change to a CM rom the battery life will increase dramatically.
I have rooted all my phones since the very first android phone ever made and i cannot own a non rooted device as the freedom of rooting is just to awsome to ignore.
Every time i have battery issues i ether change my rom or kernel and then my issues goes away...
Can't root Verizon unfortunately
Hmm. Try this. Unchecked under advanced wifi, the option to let Google and apps use wifi, even when wifi off. Since then, 12 hours, I have had normal sleep. Did reboot after Unchecked. . Premature to say I fixed it, but so far so good.
Update. Since unchecking that wifi option, phone sleeping normally still.
Update #2- after 36 hours. It's back! Awake constantly. Unreal

Ironically I see no difference in battery life.... Hahaha. But driving me nuts.
I get through entire day... About 3.5 screen hours on. At 7pm I'm at 20% typically. Maybe that's bad?

I'm usually around 40%. but maybe our app-age is different.
I've updated the Google Play Services to the new version 7.0.87 and this issue seems to have gone.
Find the apk here

Putting the 2-day battery life claim to the test

I'm usually a fairly heavy user, but this week I haven't been quite as hard on the Z5C as I normally am, and I saw it as a chance to test the 2-day battery claims.
Everything was left turned on as per usual - Wifi, Bluetooth, LTE and the like were left on for the most part. Screen was on auto-brightness, all the usual stuff. I didn't try to 'milk' it for more. I didn't use any of the battery life extending modes.
52 hours and 26 minutes later, with 4 hours and 26 minutes of screen-on time, I was at 2%. I'd definitely call that a pass.

that's amazing.. im experiencing 9 hours of battery life with 10 mins screen on time, trying to figure out how to fix wake lock with sonys tasks app and some calendar storage app but seem to be completely unsuccessfull in this... you think if i do a factory reset of the device that'll fix it?

Mine is changed out now because of faulty lens but I've used it for a few days and I got same usage as OP.
you might want to perform a full factory reset and if it doesn't solve your problem return it to Sony for warranty.
Also, do not close the recent apps constantly. Let them run in background will improve the way lollipop (and soon marshmallow) runs.

thanks i've just done a factory reset and unfortunately still same two processes are holding up hundreds of wakelocks on my devices not sure how to further troubleshoot / fix this..
processes are :
com.android.providers.calendar
com.sonymobile.tasks
does anyone know what those processes do and how i can go about just removing them or replacing with something not buggy? will be leaving for an overseas trip in a weeks time (away for a whole month) and this new phone which i got especially for it (good camera and waterproof) will be completely useless to me if the battery keeps failing on me. love the phone so far but this battery issue is killing my transition experience
had full charge at 9am and now at 4pm already at 33% battery life

for testing purposes.. do you have a calendar app? can you disable it? or clear the cache from settings >apps...There is some rogue app that is constantly accessing storage.. I've had it happen on my old phone with custom ROM.. also do you have exchange/gmail sync try changing that
for battery problems you can use Wakelock Detector without root (following the guide in the google play page https://www.google.com/url?q=https:...A&sa=D&usg=AFQjCNFCL0Z8eiWrc0xTYvz2hQAgPd3xoA ) and, if you find system apps that can't be disabled manually, you can use Debloater (windows application) http://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294 which can Hide ( pm hide command) the system apps. I don't know exactly what the command does but i hid three system packages and they disappeared from the running processes list: either they are completely hidden from the system or they are stopped and not running. For example, i hid the Software firmware upgrade app and its settings in Phone Info disappeared along with the Software upgrade notification in status bar.
My battery life was fine until I recently updated to latest fw version using Flashtool. I can't update the phone with PC Companion anymore. I'm a heavy user, I play games, watch videos, check social networks, listen to music, download apps etc. But before using flashtool battery can last me a day or so. I don't think it could last more than a day if I don't use it. At night, for example, sometimes I let the phone idle, even with stamina mode on, the phone drains 1% per hour. I don't think that's good. I hope with the marshmellow update battery can improve.

do you set up your phone after a factory reset?
U should try this: factory reset, not completely set up phone, only necessary apps like WhatsApp, Google account etc, maybe disable or remove the unneeded apps and then keep using the phone for 2 - 3 charge cycles. Then all should be good. If not, return the phone. If all is good by then, u know it's not fault of firmware or phone but fault of some app u installed.

Did u flash userdata.sin (factory reset)?
I really can't believe some people having this bad battery life.
It must be some bad app or something, I think..
The only way to test is full factory reset including wipe internal SD and then test the phone without fully setting everything up (installing apps etc)
I think I'll do a factory reset. But maybe when the marshmellow update comes, I don't want to have to set everything up again. Btw if I want to update phone flashing a new fw via flashtool is it recommended to do a factory reset before or after updating? Thanks

Mine has only maybe 30ish % left in the evening after one day with some youtube on the bus to and from work and random email and IM check ( 3-4 hours screen on total). Maybe it's youtube taking away all my battery...
I suspect it can only last until noon the next day maximum if I do my normal use and don't push it on power saving.... I don't know if I can call it a pass.. I guess it's somewhere between a pass and fail to me..
but, I do notice that it drained very fast in the first few days when I bought the device. After using it for a week it's a lot better. So if anyone is wondering why the battery life on your new device is really bad, try use it for a few days.
