I had this issue as well, and none of the solutions in this thread worked for me. However, deleting the Google Voice+ apk from /system/app has solved my problems, so I am posting here in case it solves the issue for others.

I did not have the voice+ functionality enabled, but it was still running in the background, and I decided to remove it to see if it was the problem. Hope this helps!

So I read somewhere that chrome causes a lot of wakelocks, I deleted it and battery life has improves a lot! Try it people!
[Sprint Samsung Galaxy Note II] RayTrue04:
I also get this wakelock too and it appears to have to do with fast dormancy. At least that's what I gathered from all the Google searches I did. It's also seems to be location and tower specific. I only get it when I'm at home. When I'm at my aunts I never experience it. I'm sure it has something to do with your phone communicating with the towers to enter into a deep sleep state. At my aunts the towers have been upgraded to NV and the phone sleeps fine but at home where they are still working on NV this wakelock never let's my phone sleep. It stays up waiting for a signal to enter fast dormancy state keeping the phone awake. Very annoying as it drains my battery faster..

Hi!

I had the same issue on DN3 ROM and Devil Kernel 2.3.2 but I found my own solution:

1. Download the newest modem for my device (Vodafone N7105BUUEMK2)

2. Wipe Cache and Dalvik Cache

3. Flash new modem

4. WiFi extended settings, switch to never at standby

5. Disable Google to use Wifi to locate position while Wifi is off

After that, phone is sleeping like a baby! :)

Associated with some app

Having the same problem here. I am on sentinel rom 6, kitkat on S3 LTE.

Phone was going into deep sleep until I installed the Smart Wifi Toggler. Then I don't thing that the current modem is a problem as it was working fantastic before. I guess this Smart Wifi Toggler app is activating the wifi from time to time and using the cellular network for location.

I found out that deleting Triangle Away cleared a little bit my wakelock, now it's down from 18 hours awake to 30mins to an hour... It's still there but not as much as before...
[Sprint Samsung Galaxy Note II] muhib.al.karim:
My S3 LTE went back to normal for sometime but just from two days ago it is having extreme battery drain due to this reason again.. Within this time I haven't installed or deleted any new apps!... Anyone managed to find a permanent solution to this issue or should I switch to a different rom?

PS :. I am using cyanfox 2.0.1 based on cm 11
[Sprint Samsung Galaxy Note II] jocarog:
I've changed roms like crazy and nothing fixes it, only a reboot or if I pull the battery but it comes back after a couple days... It's weird... I would like to know if it happens on stock rooted...
[Sprint Samsung Galaxy Note II] RayTrue04:
I only get it when I'm at home and it's pretty constant. Even after a reboot it'll show up after only an hour or two. Weirdly when I spend time at my aunts for like a week this wakelock is never present which makes me believe it's tower dependant. I thought it had to do with fast dormancy at first from all the reading I did but maybe it has something to do with the implementation of CFSB for tri-band phones too. Fix one thing, break another..
[Sprint Samsung Galaxy Note II] jocarog:
Well I guess we need to try a different radio then, but I had it on the radio that came with 4.1, and I thought that it was gonna go away with 4.3 (mk4) for the note I, but I carried it with me, I thought it was an app since I was restoring with titanium but a couple weeks ago I did a clean install without restoring anything from, I got all the apps from play store (a pain in the rear) and it's still happening... So frustrating...
[Sprint Samsung Galaxy Note II] muhib.al.karim:
Considering all the recent replies I can conclude the solutions to following points :

*flash a new modem

**try some other root besides cm as those have issues within

Ps:. Haven't found this issue being resolved through uninstallation of any apps!

Suprised nobody has found a solution to annoying problem yet :(

The battery drain increased even more :(

Switching off fast dormancy?

I have been living with this plague since slimbean 4.3, and now on slimkat, I still have this issue, got a N7105, so not the sprint model. I live in Hong Kong and this wakelock would kick in when I walk through some places during my commute. At work, it just happen anytime.

I have been in the US for a business trip and was using a Ready Sim, the network was using T-Mobile, I had bad connection and total blackout sometimes, never had anything better than EDGE, and surprizingly... NO WAKE LOCK for a whole week.

So ultimately, there is something wrong with the radio.
[Sprint Samsung Galaxy Note II] RayTrue04:
I've been saying it for a while now. This wakelock is location based. Almost got me ready to turn in my home keys and move in with Auntie! Something in certain towers is what wakes it up. I've called Sprint and they have no clue either.. :banghead:
[Sprint Samsung Galaxy Note II] Ash359:
I think it's caused by different things in different devices.

Seldom happens on my Note 2 but when it does it's noticeable.

It's fast dormancy related to some. It may be that one area has fast dormancy in it's network and the other doesn't.

Let me rewrite everything completely from what I know of that wakelock and some piece of info about me:

-I live in a very very antenna/people crowded area: Hong Kong, so I think my phone is constantly switching, looking, antennas (if someone has a tool to check it, please let me know).

-wakelock can happen anytime, usually the user notice it after watching the battery drain at a relative high pace. It is related to the use of DATA, I think it's more related to the use of 3G. I can't reliabily test 2G network as it miserably fail in my location, I am in a antenna black spot in my office and it is not an option for me to switch to 2G.

-I think that mdm_hsi_pm0 does have a normal behavior, if I am browsing, feedly, emailing, whatsapping... this translate into this kernel activity and in my case it's usually just a bit lower than the main activity.

-When can we say that wakelock is stuck?

To this question, I think it's safe to say that it's stuck when the kernel activity link to it is growing without stopping and is bigger than the main screen activity (unless you are downloading over your DATA connection with the screen off).

-Reports have shown that the wakelock would still occurs if we switch to Airplane mode, it happened to me several times in the past, I go to bed, switch to airplane mode and it drains my battery completely.

Right now, as a solution, we can only reboot the phone from time to time and I have been doing that every day as I arrive home (I switch to airplane mode and leave it as is up until next day morning).

After 5 days testing on a old modem ZHALI5 (reminder I have a N7105), the wakelock happened once, I tried not rebooting my phone fo 3 days and as I write this message, I saw the wakelock grow to 1h30 while my main was only 45min. Good thing is I left my phone yesterday night and it stayed at 30% battery whole night. (I did not rebooted it as I went home, but plugged the phone to the wall for 5 min just to mark the time for the wakelock app).

So, yes, it does still happen... I am sorry for bringing hopes too high. But it did not happen as much as before and writing down exactly when we should consider it a serious issue will help me do my testing correctly. I have been so much fed up with this issue that every time I would see this kernel activity, I would say "NOT AGAIN"... but I do think sometimes, it's a normal behavior...

This is just a notice.

There is no bug. No kernel problem. No data roaming need to be switched on. No fast dormancy issue.

The solution is in fact, really simple.

As someone already pointed it out, the name is a generic name. It means that something keeps the phone awake, an app most likely.

In my case, it was LINE. Removed it, rebooted. Never a deep sleep issue again. (Had no deep sleep at all when I had it installed.)

Easy way to test:

- Put a new homescreen page, add "BetterBatteryStats" widget to it.

- Start checking your apps, pinpoint suspects.

- Try removing them one-by-one and check when the deep sleep meter will start going up.

It took me an hour to find it this way. (Reboot is needed as I said.)

Have fun!

I haven't had any issue since I stopped using spare phone. Another voip app. So maybe it's the internet voice apps that are doing it.

Did you find another app that isn't so offensive?

Sent from my Jedi MasterX Note 2
[Sprint Samsung Galaxy Note II] h8Aramex:
tl;dr: Kinda, we will try Hangouts now. Just had to make a new gmail for that purpose, but that's not a big deal.

Well, the reason I started using LINE was only one person, my girlfriend.

We would send each other a hundred mails each time something happened, and that was inconvenient as hell.

LINE was also cute, which girls love (well, most of them anyway). But that wasn't the only reason we went with it.

So, other apps?

- VIBER: No privacy; no default deny all; everyone can see you/find out if you block them, bla bla bla. Terrible.

- WhatsApp: No desktop client. Otherwise, it was promising... until Facebook bought them. Double dropped.

- IM+ Pro: It never delivered messages, they would get lost, stuck, etc. It's a mess to use like the other apps. It's good when I have to talk with someone on those networks, but otherwise it's crap.

- ChatSecure: Again, messages disappeared, didn't arrive, etc. Nope.

- Facebook: ... is this a joke answer now? NO.

Recently, I found out about "KokoaTalk". It's a South-Korean messaging service, but to me, it just looks like a rebranded LINE.

Even though, they say it's a different thing.

I'll give it a try and see.

Another thing (!): With

ART

, I had no deep sleep again. || NOTE: This happened after I had deep sleep, there was no other IM app installed. || This may be due to some ART incompatible app of course, but good luck finding it. Since ART is experimental anyway and does not give a huge boost, I just went with Dalvik. But yeah, I love the idea of ART and I welcome any improvement, even if it's a tiny one.

Not like I would complain. My S3 LTE is blazing fast, much faster than the iPhone (5) I had. So yeah. Everything went better than expected.

UPDATE #1: KakaoTalk dropped. Same Viber crap. At least LINE had options to OPT-OUT of automatic stupid things. Here, it's like Viber. Everyone can reach you, and you have to block explicitly everyone. Silly crap. Hangouts it is. :)

ps.: I don't want to sound antisocial, or paranoid, or whatever. But let me pick who I want to talk with. Just because I have numbers at my company on my phone, I don't want to add them, nor ever talk with them. If I do have to talk with them, I'll call them. I find this so damn annoying. Why is privacy become worthless in 2014? And people are not bothered. They eat up Facebook and other services that give no f.s about privacy. ...

If privacy is your thing you should look at the xprivacy xposed module, the latest beta is pretty impressive.

[Sprint Samsung Galaxy Note II] h8Aramex:
Heard about xposed, I'll check it out, thanks!

(Generic privacy is not much of a concern to me.

But this IM thingie... I hate when everyone can see me, nag me. And if you don't answer, you get nagged at work for it, etc.

At least they stopped using Facebook so much... (and in the end I removed my profile because of this.))

But yeah, its terrible.

LINE was great, except those bugs. (Great == simple IM client, lol.)

Hangouts is a good alternative meanwhile.

Im owner of i9305 but had exact the same issue with the mdm_hsic_pm0 on 4.3 that was going crazy totally randomly. Hard reset after update to 4.3 Device is rooted, greenify + green power. Same apps that I was using on 4.1.2, no restore from backup - clean installed.

It was showing up totally random. No specific rule. Today after one race at RR3 I put phone on the shelf, came back after an hour and noticed battery drop. I wanted to check BBS for awake/deepsleep and how's our "mdm_hsic_pm0" having today while I missclicked Greenify. There was Chrome in awaiting for "Greenification" tab. I was like: "WTF? I haven't use chrome today at all". Checked BBS right after and ofc mdm_hsic_pm0 was going crazy.

Freezed the bastard (Chrome) with Titanium Backup, no restart and phone is sleeping like a baby. No idea why Greenify didn't put it to hibernation while turning off the screen. Weird, however I noticed couple times earlier after intensive use of my phone (using couple of apps for some time) that when I force hibernation of apps via Greenify widget - Chrome was appearing as one of hibernated apps (I'm too lazy to close each app seperately. I press home and then hit Greenify widget "Hibernate now"). But I never connected that together.

Still no idea why Chrome. It wasn't sync with my Gmail and there was no problem after normal using of app. It was just totally random.

Written by [MENTION=931226]dublus[/MENTION]

OK, it seems like several people are having problems with wake locks draining their battery.

It was happening to me too. A couple pages ago I had reported that I had inadvertently found a solution. Ever since I started charging wirelessly and leaving the screen on at all times while charging ("Stay Awake" in Developer Options) I didn't get the dreaded wake lock. This morning when I took my phone off the wireless charging dock I noticed the screen was off and didn't think much of it. About an hour later I noticed the battery had already dropped a bit and for the first time in 2 weeks the phone had not entered deep sleep. I don't think it's a coincidence. I was able to get the phone back to normal by turning on Airplane Mode and rebooting then turning off Airplane Mode.

Could others see if they can duplicate what happened to me and if they have the same experience maybe this info could be added to the FAQ?

Sent from my Jedi MasterX Note 2
[Sprint Samsung Galaxy Note II] painball:
Wait, what? If I understand correctly: Even with"stay awake" phone turned off the screen by itself when wakelock went crazy?

And back to my diagnosis related to chrome: It was a fail. Wakelock returned. I gave up already.

Oh yeah I don't even have chrome on my phone.

Running PAC 4.4.2 (KK) Mar 24 build on T-Mobile Note 2.

Always keep WiFi off and set to "never" on during sleep. Always kept "Location Services" off too.

Read WHOLE thread.

ROM had two of the five suggested lines.

Added the other three AND rebooted.

Voila. Battery life seems to be working great again. (Although the wake lock is still present, it doesn't seem to be draining the battery and my phone is going back to deep sleep rather than staying awake).
[Sprint Samsung Galaxy Note II] RayTrue04:
So I think I finally figured out what causes it! The bug is activated by Wi-Fi. In my case I always used Connection Optimizer. The bug is random when Wi-Fi is switched on, it might activate on the first Wi-Fi activation or not. It will eventually get you the more you switch Wi-Fi on which in my case CO was periodically switching on Wi-Fi even when there was no Wi-Fi to connect to. Ever since disabling connection optimizer I haven't got the bug, only got it once from manually turning on Wi-Fi.

Edit: Ugh i was just hit with it after a good 24hrs without seeing it.. Guess I'm wrong! :(
[Sprint Samsung Galaxy Note II] oxfordia:
Problem I have now is: after charging for good 8 hours, the battery is not FULLY charged. Went from @30% to only 85%. Fast charge seems to be disabled.
[Sprint Samsung Galaxy Note II] Skripka:
First thing first, replace your USB cable.

Well although i did end up getting hit with it again after thinking it was gone for good.. I must say it happens much less now that i hardly use Wi-Fi. I'm not sure if Wi-Fi plays a role in activating this wakelock but i can actually go a good 8+ hours of sleep now ever since i stopped using Wi-Fi. I used to constantly reboot as the most my phone could sleep was 2hrs. But not anymore.. Is everyone with this wakelock actively on Wi-Fi?
[Sprint Samsung Galaxy Note II] muhib.al.karim:
I don't use the wifi at all... I notice the problem occur right after I disconnect from charger... If noticed just restart it.. Sometime it fixes but sometime it doesn't... Not sure what can solve this issue!

One theory is that it happen when you disconnect from the charger while the screen is turned off.

Try only unplugging it after you wake it up thoroughly. Let us know if that helps. We are all trying to figure this out.

Correct me if I'm wrong.. But I believe his wakelock is a whole different situation from what's being discussed here. I've just realized his wakelock is not even from mdm_basic_pm0. I did suffer from the wakelock from unplugging phone with screen off but I believe it had a different name and was only present on like PALJ1/PALJC? I think it was kernel something and it was preventable by turning on screen and unlocking device before unplugging. This mdm one shows up randomly even after its been unplugged for hours.

Edit: What's even weirder is that mdm does show up on his second screenshot but wasn't present on the first one with the deepsleep issue.

Thanks for the reply... The waking up before unplugging helped temporarily... I think I started having this issue when I had a no imei issue while trying to flash a new rom.. Then had to fix that using method mentioned on xda...

Can't be hundred percent sure but I assume I have been having the wake lock problem since then..

Now I have to keep the net connection off to carry on with battery life.. Before that never had to turn off 3g..

Any ideas how to find the exact original kernel for my phone's model?
