Hi guys, pretty much just registered to post how I solved this annoying kernel wakelock!

I noticed after the 4.3 update to my N7105 Note II (stock) that the battery was draining way faster than usual, on another forum I saw a combination of things that solved it for me:

1. Factory reset and cache wipe. May not need to do this, but after upgrading to any new build it's worth cleaning the old stuff out!

2. Make sure developer mode is enabled and also make sure USB debugging is disabled in the developer options. To enable developer options, go to settings>more>about device>tap 7 times on build number (might be 10, I can't remember exactly, but a countdown will pop up telling you how many taps you have left to enable developer mode) then go back to settings>more>developer options and make sure USB debugging is unticked.

3. After this was completed, go to the dialler and type *#0228# this will bring up BatteryStatus, at the bottom there is a tab called 'Quick Start' tap this and your screen will go blank, then return and you should notice your battery life level percentage has reduced slightly. Charge it back up to 100% and repeat this procedure until the drop in battery percentage is negligible.

After unplugging at 100% and leaving my phone overnight, with Wi-Fi and data disabled, my battery was draining at 0.1% per hour. Previously, in the same conditions, it was up to 4% per hour and only a phone reboot would solve the drain before it would come back again randomly!

When my N7105 had a bad reception mdm_hsic_pm0 was triggered and kept active permanently. Yesterday, I updated my modem from XXDLL5 to XXUFND3 and the problem has gone. :)
[Sprint Samsung Galaxy Note II] muhib.al.karim:
I guess mine started when I bricked the cell phone while flashing it.. Then I flashed with some modem zip just get back my cell reception.

Any idea where and how to get the modem for s3 4G (gt i9305) international version?

Thanks in advance.
[Sprint Samsung Galaxy Note II] Schmafutsche:
Just download a odin-flashable package from sammobile etc. and extract modem.bin. Now you can flash modem.bin via mobile odin.
[Sprint Samsung Galaxy Note II] muhib.al.karim:
Quoted from a friend - AXEL. People will find this helpful.

For him it got much better with the latest Boeffla kernel version, most notably 2.3 Beta7b

Btw don't let you irritate by the "Omni" in the file name, this kernel works just fine here with CM11 4.4.4 and the latest nightlies

Good luck :)
[Sprint Samsung Galaxy Note II] paulkoan:
Hi Schmafutsche - it is a couple of months later. Is the XXUFND3 modem still working for you, and keeping the wakelock away?

Paul
[Sprint Samsung Galaxy Note II] Schmafutsche:
Hi,

I have to revise my statement, the wakelock still appears when I have a bad reception and I'm listening to music simultaneously. Maybe that could be the key to the question how the wakelock appears. I have used different kernels (Omni, Agni and Devil) with Omnirom and it made no different excepting that the Omni kernel caused audio lags (with Poweramp) when having a bad reception (or the mode of transmission is changed) .
[Sprint Samsung Galaxy Note II] cheffy11:
This wakelock will always be there as Long as you use 3g
[Sprint Samsung Galaxy Note II] painball:
That's false. It appears also in 2G on national roaming.

How do we contact Google and Samsung with this crap? This is not only happening to us it's also happening to other Galaxy Note 2 users across carriers. I think it's our Exynos chip! Can't believe this wake lock is a year old and no resolution! ???
[Sprint Samsung Galaxy Note II] RayTrue04:
I think I finally found a fix! It's been a whole day without being hit with it after freezing a certain app. Will give more details after 2 days more of testing.
[Sprint Samsung Galaxy Note II] Ash359:
It didn't m doesn't hit me every day so fingers crossed.

Try unplugging your phone without waking it up first. That almost always triggers the wake lock for me.

[Sprint Samsung Galaxy Note II] Schmafutsche:
Now I'm absolutly shure that this audio thing is keeping the wakelock permanently active. So, in my case the question is if it's caused by Poweramp or by audio in general. I forgot to mention that I'm using a N7105... So it's not a general problem of the Exynos-SOC. I think every LTE-enabled Note 2 has this problem.
[Sprint Samsung Galaxy Note II] RayTrue04:
You do know all versions of the Note 2 run on the Exynos 4412 Quad right? Actually I'm assuming not since you wrote what you wrote. We have the same processor. Anyways back to the drawing board for me. I just woke up and unplugged my phone and it's back! I really thought I was on to something by freezing a system app called MDMapp1.0 :(
[Sprint Samsung Galaxy Note II] Dond006:
Hi,

Had the mdm_hsic_pm0 preventing my Galaxy GT-I9305 going in deep sleep tested with BBS). I turned off "Synchro" in android 4.3 and MIRACLE the phone went to deep sleep for over 95%. :fingers-crossed:

So I had 3 accounts using synchro (samsung, google, email).

I turned "Synchro" on and desactivated the samsung account first and all the samsung applications (cloud, save/restore, synch etc...). This was the guilty one since my phone still goes to sleep for more than 90% when screen off. :laugh:

Samsung is really as bad in softwares as there goog in hardware.

Hope it helped
[Sprint Samsung Galaxy Note II] RayTrue04:
I've just called Samsung to report this wake lock and I suggest others do too. Maybe they'll finally look into it. I gave a thorough explanation and had the rep note my account to forward to her supervisor who in turn will have her techs look into it. This bug is too much of a headache to just sit around whining on XDA like it's going to fix itself.
[Sprint Samsung Galaxy Note II] PhilDX:
i had this problem almost every day on my VZW note 2 during the past few months while i was running CM11. it started a few months back and nothing i tried could make it stop (daily reboots, unplugging charger while screen on/off,removing apps that access data, etc.). for me, the most reliable trigger for this wakelock was simply travelling between areas with different signal strength.

i gave up a few weeks ago. i odin'd back to stock (4.1.2 for my phone), unlocked the bootloader again, and then flashed a stock odexed build of TW 4.4.2 (with modified boot loader). i haven't had a single recurrence since. i'm find myself using it a lot more now too because everything just works.
[Sprint Samsung Galaxy Note II] RayTrue04:
I've borrowed your photos. Samsung is asking me for screenshots and I'm no longer rooted so I took yours. Just a heads up lol
[Sprint Samsung Galaxy Note II] noz38:
My 2 cents:

Just to confirm it's also happening with the s3 LTE (i9305) and stock 4.3.

I think it only activates if I enable data connection during the day.

It's notre linked to 4g because I often have only 3g or h+ available.

And finally, wifi is not triggering the wakelock.
[Sprint Samsung Galaxy Note II] woodman:
Yes, and I also have this wakelock with 4.3.x or 4.4.x on my i9305.. Not with Android 4.1....

What's your ROM ? A Custom 4.3 Stock-based or a pure 4.3 Stock from your carrier ?

Did you change your modem and your CSC ?
[Sprint Samsung Galaxy Note II] noz38:
I'm using a pure stock ROM from Sammobile: I9305XXUEMKC

I replaced the original modem XXUEMKC with XXUENE2 but I didn't feel any difference in the frequency of the wakelock.

I'd say it happens about 1/3 of the times I enable data connection.

Everyday I have to open BBS, check the deep sleep count, lock the phone, wait a few seconds and come back to see if the deep sleep has changed or not. If it didn't, I must restart the phone to remove the wakelock before going to bed, or the phone will shut down during the night, the alarm won't go off and I'll be late for work... Happened once, it was a great day, thank you Samsung :rolleyes:
[Sprint Samsung Galaxy Note II] woodman:
OK, I was wondering if a bad combination of PDA, CSC and MODEM could be the culprit. That's why I asked you about this...

Here is a tip (in case you don't know yet) for BBS to ease the detection of 100% awake time : in paramters go to watchdog and enable it (with notify option) ! It will avoid you to check manually deep sleep time...

Ok, did you try to delete data of the app, configure again and retry watchdog ?

Or maybe a compatibility issue of BBS with your device or your ROM...

[Sprint Samsung Galaxy Note II] Ash359:
I cleared it's data and tried again. I switched on watchdog and turned the duration threshold to 30 minutes.

Seems to be working great now. It actually caught the wakelock and notified me.

Thanks

[Sprint Samsung Galaxy Note II] woodman:
Ok, nice !

But why do you set a so big threshold ?
[Sprint Samsung Galaxy Note II] Ash359:
I have several smaller wake locks that are insignificant.

Also my Bluetooth has a wake lock and will trigger this while I'm commuting.

30 minutes is plenty short enough. Is there a notification tone to set?

Sent from my Jedi MasterX Note 2
[Sprint Samsung Galaxy Note II] woodman:
No tone to set with watchdog. As it's triggered when screen is turned on, there's no use !?

Just a quick update from my i9305. We were lucky enough to get kitkat last week, I didn't get the wakelock since I flashed it with odin.

Now I might need a few more days of testing since I don't use data connection very often, but it looks promising!

Maybe it's kitkat, maybe it's the 70+ apps i removed from system/app and priv-app...
[Sprint Samsung Galaxy Note II] woodman:
I think it's kitkat 4.4.4 update effect, that's what I also read thanks to [MENTION=5172716]painball[/MENTION] on community rom thread here http://xdaforums.com/showthread.php?t=2759082

[Sprint Samsung Galaxy Note II] woodman:
Hi, sorry for late reply :)

EDIT1 : could you please make screenshots of all your BBS stats ?

In my case I sometimes have this wakelock (power manager service) and it's triggered by my 3rd party music app (Deezer music).

To fix this I greenify my music app.

But this wakelock is triggered by many other misbehaving apps or system process. You have to dig a little. :)

EDIT2 : or, try to disable fast dormancy...
[Sprint Samsung Galaxy Note II] muhib.al.karim:
I had this wakelock issue for pretty long on my Galaxy s3 lte running cm11.

Then I flashed the stock rom 4.4.4 which came out couple of weeks ago via Sam mobile. The performance was great so far. No wakelock and could really feel the difference in battery life.

Now since this evening I am again having serious wakelocks!.. Would appreciate if anybody can help out...

Thanks in advance.
[Sprint Samsung Galaxy Note II] lecomarreco:
Wow .. I can't believe that this issue is going to its second birthdate without any concrete solution.

I just read the WHOLE thread hoping to find a definitive solution but it seems that nobody found out yet.

I have the issue of 0% Deep Sleep in BBS and the most guilty is the mdm_hsic_pm0.

My device is a I9305T ( S3 LTE) with a custom ROM: CARBON-kk-NIGHTLY-20141106 running into a Boefla's kernel 2.4 beta7. When I was on Wanam Lite 4.1.2 based ROM I've never had this awake problem.

Last week I flashed the Cyano 10.1.3 and this nightmare started, 100% awake time and the battery going to hell.

Then I flashed the 4.4 Stock from sammobile looking for a fix, but I couldn't stand that Rom for a day. ( Samsung rom Sucks). It only gave me the new KNOX bootloader

Now I'm on the Carbom ROM 4.4 based with baseband modem from 4.3. ( It has the better signal and 3g speed).

But this nightmare keeps waking me up, actually keeps my phone awake. :p

Today my battery went from 100% to 1% in only 8 hours, with lass than 1 1/2 hours of screen on. 100% awake time, not even a second into Deep Sleep. ( my phone has all the lines on build.prop someone suggested some post back)

After all I read and tried I really think it is related to Data Connection. In my case there is nothing to do with Wifi, Bluetooth, Gps, etc.

I've made some tests today and the problem was triggered only when I turn off the screen with data connection activated.

The mdm_hsic_pm0 running time still counting with the screen off. If i turn off data connection before turning of the screen the process stop running, phone doesn't go to Deep Sleep though.

Turning of data and rebooting the phone stop it and get the phone temporaly into deep sleep mode. I'll try to flash a 4.1.2 modem and watch its behavior hoping for a solution. I can't flash a 4.4 modem yet because I have a I9305T model and there is no such a modem for this device, actually I can flash the I9305 universal modem, but I don't want to lost my 4G connection due to different working frequencies.

If anyone know how to stop this battery serial killer let me know, it's driving me crazy.

Sorry about my english, hope I've made myself clear.
[Sprint Samsung Galaxy Note II] PhilDX:
the solution for my VZW Note 2 was to revert back to a TW ROM. i tried everything before that. i failed. haven't had a single problem since though, more than two months now.
[Sprint Samsung Galaxy Note II] lecomarreco:
Good to know that it solved the problem. I just flashed an old modem, if it doesn't get better I guess that will be my way out aswell.

Did you flash a custom or stock ROM? 4.4 based ??

Thanks dude
[Sprint Samsung Galaxy Note II] PhilDX:
i flashed a pre-rooted stock ROM for my device, it's TW4.4.2.

while I much prefer CM over TW, I have come to appreciate the stability of the stock ROM. to be honest, this wakelock really wore me out. I never bothered to experiment with any other TW ROMs once I realized the stock TW ROM solved this issue for me.
[Sprint Samsung Galaxy Note II] lecomarreco:
I guess I'll need to give TW a try.

I flashed an old modem yesterday nigth. Fully charded my phone and let it screen off and data On over the night. About 8 hrs.

For my surprise it got into DeepSleep for 90% of the time with only 30 min awake.

But something is still draining my battery because it went from 100% to 84% at this same period. I don't think it's a normal rate. I see people around stating 2 - 4% for 8 hrs inactive.

16% is not acceptable for 7:30 h into deep sleep.

I already grenified a bunch apps and disabled some google services that were keeping it awake.

I'm start considering my battery is getting old.
[Sprint Samsung Galaxy Note II] PhilDX:
My comments were specifically in regard to the mdm_hsic_pm0 wake lock, are you sure that's your problem? If something else is creating the problem on your device, it might be related to one of your apps.
[Sprint Samsung Galaxy Note II] lecomarreco:
Yes, I'm sure this is the biggest problem.

Updating my status. The old modem did not solve it . I just get the service pm0 back awake all the time even with off screen. I just drived over the street on different signal areas.

Rebooting the phone stops that service and put it into deep sleep again.

But as I've said before there is

something else draining the battery even when it's in deep sleep. At least the BBS shows deep sleep.

Audiomix is another service that is keeping it awake. But with the pm0 service always on it is useless to disable or greenify anything else.

I'm looking for a good TW based ROM for.my device and will give it a try.

Thank you for the tip.
[Sprint Samsung Galaxy Note II] lecomarreco:
Just giving a feedback.

The TW base ROM solved my problem aswell. It's a 4.4.4 TW Stock Based.

Thanks PhilDX.

Still working?

I have the T889V and I've been using a stock rooted 4.4.2 ROM for months. The wakelock has been coming and going but for the last few days it's been practically impossible to get rid of it. I'm rebooting several times/day and it's not always fixing it. In the past I could go for weeks without the wakelock but now it seems there's no getting rid of it. Does anyone have a solution yet? I thought I would keep this phone for a couple of years but this is getting beyond frustrating and I'm pretty sure that I'll never buy another Samsung phone or tablet.
[Sprint Samsung Galaxy Note II] PhilDX:
even though i've moved on to a nexus 6, i still pay attention to mdm_hsic_pm0 wakelock topics across forums and i haven't noticed any new developments. the note 2 is a great device, but if the stock ROM no longer solves this problem it is very sad news indeed.
[Sprint Samsung Galaxy Note II] heathcliff06:
After a long time I just reavicated my Note 2 LTE (N7105) for using it as an outdoor device.

Has the mdm_hsic_pm0 issue ever been solved? I know that there was a fix in Lineage OS, but I remember thats calls often were disconected and that GPS did run bad @ Lineage. That was no solution for me.

For the moment I run Omnirom on it and I added - after the issue came up again yesterday - "ro.semc.enable.fast_dormancy=false" to the file "build.prop".
[Sprint Samsung Galaxy Note II] MeetFace:
I was simply analyzing the information provided and giving suggestions.

On a related note, the times I've seen this wakelock the highest were when I had GPS enabled all day. I typically leave GPS off, it's a battery killer in low-service areas.

I have a hunch that it's not related to Location Services. I have had the same battery drain issues since last weekend and location services has been on since I have had the phone (almost a month.) I enabled the Samsung Push Service on the weekend before I knew what kind of battery hog it was (as I went into Samsung Apps to get Polaris installed) and uninstalled that.

When I go into battery usage settings on the phone (not BBS), it highlights Polaris and the default video player app as big draws on the battery. Still trying to figure it out ultimately......
[Sprint Samsung Galaxy Note II] Skripka:
I have the mdm_hsic_pm0 wakelock on PACMan ROM...seemingly hung. It prevents my phone from ever deep sleeping. GPS on/off does not effect it...Google Now on/off doesn't effect it...Location services doesn't effect it.
