Yesterday I had this problem with l2_hsic......
Read the rest here
I moved my post because I will need the space for the findings, as I don't see the light at the end of the tunnel.
Here are the findings till now from some users.
I will update this when new ideas/solutions have posted.
what is l2_hsic read the rest here
anirudhgargi said:
HSIC is technology for inter processor comminication. Our phone has two main chipsets AP (here snapdragon, thus the name MSM ) and modem chipset (again by qualcomm). They both are connected via hsic, ...........
anirudhgargi said:
Yes, HSIC is an hardware along with its device driver used for Inter Processor Communication.
Main principle is Android RIL communicates with help of hsic driver to communicate to the CP (modem) chip. And vice-versa. Modem chip also has the same hsic at there side also.
.............
That L2 does not stand for L2 of OSI layer................ There are 4 states (L0(active),L1,L2,L3) state of power saving in USB link also , hsic also uses the same convention.

Hello
I've been encountering L2_hsic and a few other related wakelocks for months (even years), ever since updating my I9100T to ICS (which I did the minute custom ICS roms hit web).......
I searched around and found out the l2_hsic wakelocks are generated by a kernel file "/drivers/misc/modem_if/modem_link_device_hsic.c" which is also responsible for rpm_hsic and tx_hsic wakelocks.
From there I went to CM git and with help from their IRC channel I found the source code for their version of this file:

A explanation from anirudhgargi what hsic is! (09/06/12) post 264 :
anirudhgargi said:
HISC is the interface that connected the main Soc processor ( Also called Applciation Processor AP) to the modem ( 3G or 4G if there are two modems separately )
HSIC is used the standard USB core library. And it is stanrd given by usb.org. The HSIC by itself consumes very less power and is one of the very power efficient and space efficient ways of interconnecting chips. Currently common to Qualcomm and Sammy Exynos architectures.
The reason you seeing too many HSIC wake lock and other wake us's is due to the fact that the HSIC interface is waken up by modem (Normal scenarios are also so many) .

A sume of what we know from Shaftenberg(20/06/12) post #136
shaftenberg said:
- equal which modem we are using (GB or ICS)
- all available kernels are affected
- all ICS-ROMs are affected
- disable fast dormancy doesn't help(?)
- Wifi settings aren't responsible
- AC charger is equal (maybe a random thing for this user)
- turning airplane mode or data on/off does not help to kill the service

a found on the kernel code from funky81 (25/06/12) post #179
funky81 said:
After search codes in the kernel related with this problem, I've found out the conclusion is that this wild uncontrolled wake lock related with data communication (modem)
Code:
./drivers/misc/modem_if/modem_link_device_hsic.c:wake_lock_init(&pm_data->l2_wake, WAKE_LOCK_SUSPEND, "l2_hsic");
I will try to update the code w/ Samsung Galaxy S3 source code in my kernel...
I will inform you if there's any progress with this

I have the same kernel wakelock l2_hsic in my phone when it is otherwise idle... no idea what it is though, but in my feeble understanding it means that the phone never gees into deep sleep - and that can't be good can it?
I have the same problem of the l2_hsic wakelock popping up and eating battery. A reset always cures it for some time but it eventually appears again... Very annoying, I hope someone figures out how to get rid of it..
Same here, l2_hsic keeps my phone awake. It's seems to start at some random point and never "switches off" again until I reboot the phone. After a reboot it takes usually takes a couple of hours before this lock reappears.
Never saw this lock on GB, btw.
I'm having the same issue too. Has anyone figured out what it is yet?
I gave up.
Went back to Gingerbread using PC Odin and flashed a pre-rooted LA1.
Installed Mobile Odin Pro and flashed official LPY using Everroot and the 2 injects.
So far it has been running nicely with no wakelocks worth mentioning.
Disclaimer: I am a noob, what i have done might be unsafe and stupid.
same problem here. I also have not found a solution, even though I force-stopped all installed programs it was still there. Bad thing, it reduces my battery life from about 3 days to 14 hrs :/
i have a bunch of random kernel wakelocks that randomly start up and keep going. l2_hsic is one of the worst offenders tho.

Update: Phone is doing great now, with uptime of about 36h.
L2_HSIC does show up in kernel wakelocks but only for about 10 minutes in this 36h period.
Yesterday it seemed like my note cured itself, the l2_hsic wakelock was up for about 10 minutes and after 19 hrs I had 45% left. Without changing anything today it is worse like before. The Samsung-Support did not know what to do except for a factory reset, but I'd really like to find a better solution.
It seems like a restart cures the wakelock for about 24 hrs. I restarted it 1 hour ago and until now the l2_hsic hasn't come up...
you mention "2 injects" -- what are you referring to there? I did the LPY flash via mobile odin pro, but still have the l2_hsic battery drain issue, so perhaps I can try the '2 injects'?
edit: oh, SU and everroot?
SU and Mobile Odin with Everroot selected as well, of course
this deep sleep issue is the reason i went back to gb. believe me this issue will keep coming. im aware that rebooting by turning it off could fix it, but once u charge ur note while awake it will lock at 200mhz again. so annoying,..

You're right. I have the same problem. A reboot fixes it but it's always back when you least expect it. You only notice it once the battery is down by an inexplicable 20%
How do we bring this to the notice of someone who knows how to fix it.
On gingerbread I have other wakelocks. "gps" and sometimes "fuel_alerted".
I joined the club and have this strange wakelock too ^^
Only 4,6% though, so it's no battery drain but regardless of that i was curious and wanted it removed :
Hope there is a more permanent solution for this than rebooting
I use the LPY rom together with CF-Kernel LPF. I had the l2_hsic problem too. For me reflashing the kernel with mobile odin resolved the problem.

I stand corrected, it DID come back, L2_hsic startet some 4h ago and never stopped again.
I've had it, I'll switch to CM9.
When on charger, it's always awake at 200Mhz...
I've read somewhere that if you unplug from charger with the Note in "sleep mode", it will not enter Deep Sleep.
I had the fuel alerted wakelock because the bat was down to 5% and charged it and unplug it while screen off.
Also had the "no Deep Sleep" problem, but after I've started to wake up the phone prior to unplug the cord, it sleeps like a baby (2 days with usage) and always deep sleep when screen is off (checked by spy cpu).
Hope it helps...
Regards

I've also read this somewhere on xda. And when I had the problem it was exactly like this. The problem was there when I unplugged the phone with the screen off.
Sent from my Galaxy Note running ICS
Unplugging while "Awake" is not the solution.
My phone goes into this permanently awake state randomly after upgrading to ICS. (I am stock, and upgraded via Kies...never messed with this phone before). I too noticed the L2_hsic taking alot of time.
I have made a concious effort to investigate this, and I can confirm that unplugging the phone while "awake" as a solution is false.
Not once since I discovered this problem have I unplugged while sleeping, but alas, I am again in a zero deep sleep situation.
Back to restarting this stupid thing every 2 days after finding my battery draining 15-20% in some short minutes.
I abslutely love this phone!!! Best in the world hands down!!! I love ICS!!! But if this problem doesn't go away, I am giving up! Samsung is both the best...and the worst!
I'm using Kingdroid v7.1 with notecore v10 kernel. But even before these, the phone never goes deep sleep after unplug the charge until i reboot. I read some blogs lots of people have this issue on ICS. Have you face it and did you solve it?
Thanks.

Try not to install app that has something to do with your cpu or access to, for example temperature and consumption. This i notice when i install those app then suddenly i had wakelock problem. This is only my own observation.
Others said after charging unlock your phone first before pulling the cord.
I've also heard this,
Unplugging while locked leads to issues for some....
Personally I'd throw BetterBattStats & CPU Spy on and see what information you can get from here...

this is a complete bull**** myth that belongs to fairy tales!
what does locking the phone (pulling the charger) and the battery drain have to do in all of these??
I never read such a silly and crappy advice than this... this gotta top the lists of silly jokes on my end
anyway OP.
Don't rely on mumbo jumbo advices. These advices are worthless and totally just a piece of crap
I would go with the advice of just totally wiping your phone first.. don't install 3rd party apps(aside from cpu spy) on your phone, disable all background syncs, datas, 3G wifi, and BT.
With CPU SPY (the one app that you only need to be installed on your phone)... check back if your still getting deep sleep ish...
in that way.. you can really try to resolve your issue thru the process of elimination thru careful selection(of apps your going to install one by one later on)
This RILJ wakelock on the dialer seems to be impossible to remove. I've tried everything from disabling all apps, turning off the phone and turning it back on with airplane mode, TWO factory resets, turning off all GPS and location services, and even shutting off my mobile data. I even did all of those steps at once and to no avail.
I'm running stock right now but I seriously can not use this phone when this wakelock is disrupting my phone every damn second. I don't know if this is the right section to post this, but is anyone else experiencing this issue? Is there even hope?
I've tried what feels like everything. I feel like this will drive me crazy to the point where I will just exchange the phone and claim battery problems. Again, sorry if this is the wrong section to post this in, and I feel like such a dirty leech making a help post as my first post. This is my first android phone and I have a lot of experience with java but I need to feel secure with my new phone before I start delving into development.
Are you talking about a wakelock you see in a battery monitoring program? Or an error that keeps popping up?

Yes I understand this, but the wakelock shouldn't be going off over 2000 times, right? I mean, I'm totally new to android but I've never seen this wakelock before. I'm in NYC and usually have great reception, right now I'm getting 4G LTE 3-5 bars constantly. Could it be a hardware issue with my radio?

OK, so before I answer that, what sort of battery are you getting? What's your screen on time?
All android phones have this wakelock. It's not a hardware issue, 100%
Oh, I'm sorry but I also thought you meant a different wakelock xD RILJ wakelock is caused by having a lot of location services on, turn these off (Google Maps, Latitude, Weather constantly refreshing)

Here is the battery I was getting (can't post links yet, imgur is very safe): imgur_com/a/jCBG4 Thanks for the speedy responses btw.
I have essentially every single service off, only google's anonymous location service which is required for the weather app to work. All the sync stuff I can't turn off is set to refresh at the lowest intervals.

You're welcome. I have the same set up as you and I average about the same battery life, I think your device is fine. I would just stop looking at your wake locks and enjoy! Try flashing ARHD rom! The new base adds 2+ hours battery.

I didn't have this wakelock for those pictures. This thing is sapping my battery life causing an extra 1-2% drain an hour, which adds up quickly. It also doesn't let the phone enter deep sleep if I remember correctly.
Hello all
i´ve got my 4x Hd since one month now, everything is okay but the battery live is terrible. In some reviews i read that the phone should get 6 hours of screen on time and a lot of users here say that they reach 2 days with this phone but the maximum i reached with my phone was 20 hours with 2 hours screen on time. And no, i dont play ANY games on my 4x and the screen is nearly on minimum brightness. I have tried EVERY Rom in this forum (rom folder contains 80gig, lol) but it is very hard to manage for me that the battery lasts a day. Better Battery stats says that Baseband wakelock and wifi wakelock drains the battery at most (even on v10h and v20a,I thought that these wakelocks are custom Rom related...?). Also ive tried a lot of battery saving tweaks like greenify for facebook, trickster mod to reduce voltages and underclock to 1ghz, but nothing helps much. I ordered a second battery too (polarcell) and it gives a light improvement, but coming over an day ist quite impossible...
I would be gratefull if someone can suggest me a good setup (Rom + Kernel + Apps) or some tipps to save battery...
Sorry for my "bad" english....:0

According to what he has written, he seems to have searched and practiced a lot.
Please just ignore the question if you do not want to answer.
It is nearly impossible to filter good knowledge from a thread which has been started months ago so sometimes it is good to make a new start and share the most useful.
6 hours is overkill of onscreen time. 2 hours is what you should get with heavy use, 3 hours with moderate, 4h and up with video watching.
install custom rom and kernel, keep wifi and data off while phone is idle and you'll get miniscule discharge while the phone is not in use. if you need to sync messages or mails, use dsbattery saver, and let it turn on wifi/data once per hour for 2 minutes and force sync.
keeping data and wifi off will conserve a lot of battery.
baseband_xmm is weird wakelock. try werewolf kernel, as it seems he completely fixed it from overeating the battery. as for wifi lock, it seems that it's rom-related, and that stock has best stats with wifi on, but a bypass of that issue, is ofc, to use wifi only when you need it.
as for underclocking & changing governors, i didnt find that they increased battery life much (for me). only advice is to experiment, and from personal experience see what's the best you can pull off. (f.e., carbon 4.2.2 i could pump 4+ hours of onscreen time with medium use, but i've tested other (better) roms, with more functions, that i simply dont want to go back to it )

If that is true then the OP should have been able to formulate his own opinion as to which ROM and Kernel works best for him. The simple fact is that if he's only had the phone a month and has tried every ROM then he has only run each one for about one day - that is not enough time to form any kind of opinion on how a ROM actually performs. By far the best thing is to choose 3 or 4 ROMs that have the features you want and try each one for a week, take copies of the Bettery Battery stats and review after doing those tests.

If everybody could understand this fact, there would be less questions on the forum.
No custom ROM or kernel can create miracles when the power consumption of the screen is the unchanging variable in the equation and you have to turn the screen on to use the phone.

Thank you, actually i´m using a modded stock rom (p880-eur-20b-f1.zip) and because of wifi and data issues i moved to the werewolve kernel v8 because it promised to get rid of the wakelocks but everything stays the same...Disabling wifi is annoying but possible for me, but disabling data is no option because i need whatsapp....and i dont understand how a lot of people here say they have a good battery life without disabling anything... :l Carbon Rom had alot of other bugs for me (needed 10 seconds to show the lockscreen), 4.3 version was even worse for me :l

Wtf ??? When you listening to music phone runs 51mhz. I can listening about 2 days music. I think you have very many wakelocks I listen to music after 1h 2% was drained.

yeah, that's not normal. even with gaming it should last more than 30 minutes. my best advice is to dig deeper into the issue, see what's really wasting the battery. not many tips i can give, since my worst drainers were wakelocks, not apps using abnormal amount of battery while phone is active
Recently my nexus 6 has been having pretty poor battery life. It estimates about 5 hours left on a full charge when before I would have close to double that. Im running franco kernel r25 on stock android 5.1 build LMY47I. I've heard the new google play services update could be a problem too.. which is version 7.0.99 if that helps. Please, any help would be great. Thanks!

Still not sure what your asking of me... Do you want me to download an app? or am I looking for a specific setting?

an app. its called wakelock detector
There are lots of settings but wakeloc detector will tell you real quick what's going on. After that we can go from there. Also you might update to Franco's test build r26, its a couple pages back in his thread. I think it fixed a few wake issues.

franco himself said that build would not effect wakelocks in anyway. It just modified the idle loop in the cpu scheduler to allow the cpu to idle easier.

I thought I had seen the opposite posted in his thread. Could be wrong though.
just copy and pasted his post. At least thats what I got from this post.
"If you wanna test a new feature of r26 which is a patch from upstream that instantly idles (idle is not offline, it's a shallow power state when there no jobs running on the core to preserve energy) if a core is running with <= 1 job instead of going through a idle_balance() loop which goes on to decide if the core should or shouldn't enter idle, and it's not cheap. With this patch it also reduces the overall load_average since it reduces idle_balance() calls by 75%. In theory it should improve battery life. boot.img attached
I don't have numbers, but I sent the patch to imoseyon and he's already testing it. With your help we'll get some pretty numbers soon. This is completely agnostic of wakelocks, so if you have them, you're on your own, like you always are."
This is what you want see in wakeloc detector. As close to 0% as you can get. Just find out what's running/waking up and start working on stopping those.
Wakelock Detector is great but I honestly like Better Battery Stats better myself. Look for the XDA version on here, it's free

GSam Battery Monitor is also very good and detailed regarding Wakelocks

I know a ton of people love gsam, but whenever I've tried using it, it just gave me that bloated app feeling. If it works for you that's all that matters.
I use gsam also just to check how things are running. Greenify once wakeloc detector tells me what's going on.
I downloaded an app called battery doctor and that has helped a lot. Going on 31 hours with moderate use
But google play services is one of the things draining the most of my battery.
I too feel like I'm struggling to get passed 1 day with really hardly any use. My phone sits on my desk most of the day and I peek at it if it goes off. Most of the time when I do get a notification, I check my gmail on the PC, as well my messages via Verizon Messages (though I still use Hangouts on the phone). It never fails by the time I get home, I'm usually around 40% battery and I feel like I've hardly touched the device all day.
I've download WLD which I've used on previous devices so hopefully I can post back after today and see what's draining my battery.
