[Q] msm_hsic_host wakelock keeping s4 awake - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Today I noticed this wakelock kept my device away 80% or more of the time it has been on battery (11h13m at the time of posting this). To give you an idea of how little I used it in the time screen on time is only 33 minutes. And the only time I used it for anything was when I had the screen on. I can't seem to track down any info on what would be causing this wakelock on my s4. I found in a google search about this on other devices like the nexus which pointed back to a thread here on xda that said it is due to " the 3G modem is connected to the phone as an external USB device controlled by the hsic host controller". Problem is I don't use USB for anything with my s4. No new apps or changes have been made to my s4 in ages so I can't even contribute it to anything that has changed recently. I use the same apps I have been using for ages. I've been home all day today as I had the day off. I use wifi at home. CPU spy lists my uptime as 29 hours I rebooted last night while out with friends because flixter wasn't working right. After the reboot flixter worked fine. And I put it on the charger when I got home. In case any of this has any bearing on this. Is there a way for me to find out what causes(ed) this wakelock on my s4 so that I can troubleshoot that thing and make any reports needed to the respective people to correct the problem causing it?

I have kindoff the same problem

I also have the same problem with my s4, I installed greenify and DS battery saver but they don't help. My device wont ever go into deep sleep!
I am on 4.3.1 and the thing is that I have something broken on my modem too, so maybe my situation is different. So I'm trying to use my device as a tablet but my battery gets eaten away like hell.

Battery life suddenly very poor - how to identify cause?

For the first few weeks I had my HD the battery life was brilliant. With minor use it'd have high levels like 95+% when I go to bed at night, but the last week or two something has begun really guzzling power from it and I can't figure out what.
I don't think I installed anything new, so I want to find out if there is a way I can easily identify where the power is getting drained so badly. For instance, some days now it is down to about 55% by the middle of the day without even making a call or using any data services etc. I have bluetooth & wifi switched off all the time too!
Is there an app that can identify battery drain in a similar sort of way to cpu/memory use? Or does it normally follow that something using more memory/cpu will be the cause?
Thanks guys!

Try the following task manager and click on CPU Usage at the top. This should help isolate what programs are active
Thanks very much for the reply.
I did look in a task manager I already had and I found that Phonex seemed to be varying but generally using up to 10% cpu just sitting in the background so I have uninstalled it (shame - it's nice).
I'll add in the task manager you've given me and check that, and see how it behaves now PhonEx is gone.....

Here's an update - I couldn't find anything else that was really using any cpu, and the main culprits using memory seem to be important stuff (I think - shell32.exe & device.exe & cprog.exe) so I doubt I can do anything about them.
Anyway, it wasn't bad last night after removing PhonEx but this morning it had used 10% battery in half an hour without even being used at all!!!
Rebooted and it's stayed on the same battery level now for over an hour but I don't trust it - it seems very erratic and I'm really not sure the best way to find the cause still.
I'd do a hard reset but it'll be a right PITA to get everything back on it again afterwards.

I would recommend reading this thread
A number of ideas have been given including using SQTools to identify what is using up the battery.
Good luck and keep me informed
Thanks for the reply again.
Are SKtools/SQtools two different things, or is that just a typo?
Have already got SKtools installed so I'll give it some scrutiny. It's obviously behaving at present though as it's an hour since my earlier post and still on the same battery % level.
Thanks for the link to the other thread anyway. I'll obviously be keeping a close eye on this so I'll advise any findings as they come up.
I've never known anything like it with this battery - no regular pattern sometimes brilliant sometimes awful. Very sensitive to chargers and type - one person reported here that if he charged through usb on computer his battery life went down really quickly afterwards. If he charged through mains battery life was much better. I also just found my charger on my motorbike has a small amount of rust/dirt in it and is causing the device to discharge.
I am not helping but just reaffirming your findings. I did find a programme called BattLog useful to see what programmes were causing high level battery usage. I don't have the link but you can find it here somewhere using search. Another tool for your collection.
Good luck!
Battlog eh? Thanks for the suggestion - will look it up
*edit* here it is - I'll try this tonight, if only as it's quicker than going through the SKtools menus to get to the power usage:
http://www.freewarepocketpc.net/ppc-download-battlog.html
I just began uninstalling stuff to see if it helps (seems to currently run around 106-111mah drain - no idea what might be considered 'normal' and have seen other posts questioning this but no real answers - yet).
Uninstalled Memmaid, and the wedge 18 tab action screen, and also Singh's 15 tab thingy. Have also turned off Handy Switcher as I had that running from startup. It's still drawing 106mah after all that!
One side effect though after removing those, was the weather applet appeared on S2U2 when I unlocked it - first time it's worked! It did disappear again though so there's still a problem with that too.
I've seen many posts where people blame software they have installed and the developer denies it is the software etc.... I think in the end it comes down to the device/battery or manila/TF3D. I may be wrong of course and will be interested to see how you go with it all.
I think it must be software since I have a lot on there and it was fine for the first few weeks I owned it and then suddenly began losing LOADS of power.
For some reason my data connection is not working now either! Might be time for a hard reset I guess.
If you are getting ~150mah consumption when the unit is in use, then with a standard 1350mah battery the lifetime should be 9 hours per charge.
If your battery dies in 1 day, then the unit is consuming the same amount of power almost all the time, even when it's locked or sleeping and this is not normal, unless you want it this way.
Some software, in particular lock managers and button managers are believed to be causing battery drain as they prevent the device from entering deeper sleep states where power can be conserved.
There's software floating on this forum that enables wi-fi and wave audio drivers to remain active in unattended mode (when your backlight is off) too, battery is drained a lot faster when any of these are installed.
Good points
I doubt there's any way of monitoring what power is being used in standby mode is there?
For instance, would an app be possible so that when sync'd and usb charging turned off the app on your desktop could run the same power monitoring process that you find in the likes of SKtools? That would answer a lot of questions I think!
PowerGuard
I used PowerGuard, when I was troubleshooting my battery problems ... and you can run the monitor and put it in standby mode, backlight off etc. I used to consume ~180maH when on, no calls no bluetooth and ~96mAh when backlight off/standby.
For me the culprits were S2U2 and Enable HSDPA in the phone settings. I cant get 3G cause im in the US, but it was alwys searching for a signal... after disabling those two.. im at 115mAH when on and 33mAh when standby and back to an ~18 hour battery life.
Oh dear, I just made a new thread with the same question really Silly me.
What version of S2U2 are you using? Did you upgrade that recently? I moved up to 1.5 and I think that might be the culprit, but I've uninstalled it and still having poor battery problems.
**EDIT** Okay, so I have Battlog installed, the drain sometimes shows as -330ma, but how do I see what is causing that drain?
My battery was lasting 2 days on the standard rom, using S2U2 and with HSDPA enabled.
I then upgraded to the Davideuck V-1 HP, and changed the radio from 1.09 to 1.12. Again I did have SU2U installed.
The battery then lasted about 6 hours, and the unit shut down before the ending of my day at work. I can only assume that the pda was consuming too much power even when switched off.
After two frustrating days, I gave up last night, and installed Davideuck V6 and changed the radio to 1.10, and now the pda battery is lasting for ages. It's only dropped from 100% to 99% after 5 hours.
OK, I know I should have changed things one step at a time, but I must assume that either the 1.12 radio or the V-1 rom is causing the problem.
I don't think S2U2 is the culprit here. But I do suspect that it might be the V-1 rom, as I believe that some folk have a similar problem with the new Dutty rom too. However, other users of the V-1 rom assure me that they don't have such a problem, so I'm confused!
Hmm, Dutty's 2.0 is using radio 1.09. Maybe I should try 1.10? Where can I get it from?

There should be for example "Active Application=ThumbcalStart" just above the temp/ma figures in the log file like in this screen shot post 17.
I am guessing 330ma does not sound too excessive for an open application as long as it is not running all the time.
So, idle it's at around 90-100. When I turned it off and S2U2 didn't start, it dropped down to 33 fairly steady. When I locked S2U2 and then turned it off, it stayed around 80, dropped to 50 for a little while and then came back up to 99...

Random Shutdown

When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up
nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.
interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model
yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.
it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.
Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.
Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm
This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting
I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.
Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.
Should send back for warranty
Sent from my GT-I9000 using XDA App
software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....
i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running
OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.
«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.
Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.
Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?
Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.
I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.

Gets hot and uses battery while idle

Recently I have noticed on several occasions that my phone have gotten hot and started eating away the battery. One time I had around 30% battery and the phone was laying in my pocket. I felt the heat through the pockets and took it up to see what's up. It then had 0% battery and turned itself off.
When looking at battery use in settings, it's hard to pick out one specific application that might do this. If anything it would have to be "Android system", right now it's tied with the screen on 40%, but I charged the phone an hour ago and I haven't used the screen much.
Edit: I should add that the same thing just happened, from 99% to 89% then it stopped. That's why the information above about battery usage is relevant.
Do you think it might be hardware-related, like a partial short circuit or something, or is it most likely a software thing?
Bump. 10 signs.
Had mine for a few days, have not experienced anything like what you describe
I have though felt the screen get hot when turned on full brightness and reading a e-book on it (white - black text)
Well this is while it's laying in my pocket, with the screen off, so it's not the screen. (it's the battery that gets hot)
Take it back.
[Funny story that probably isn't relevant. I had a dodgy micro sd card that made my phone drain battery super fast and as a result my phone got incredibly hot. Took it out and it's back to normal.]
Sounds software related to me, your android system should definitely not be 40% of your battery. It sounds like some rogue app/process is utilizing your cpu and thus your battery very heavily. If you select the "Android system" in the battery usage list, does it not give you a further breakdown of what is included in that that is using your battery? Also, what does it say for the cpu time for the android system?
May be firmware bug
I've had this happen to me a few times when I was running the original firmware. In some early firmware there was a bug related to switching between wifi and 3G, which would get it stuck so that you couldn't toggle wifi on or off. The times this happened to me, it was also stuck in the wifi bug (although I had the wifi bug and it didn't drain the battery).
I now run the newer firmware (JG4) and both problems have stopped.
I've had this problem with my asian i9000 since the beginning. The app called Top showed me that it is ksoftirq/d that is running and System Panel showed me that the cpu was running at 100% at 1ghz.
At first the only solution seemed to be restarting the phone. However some information shared on this forum led me to try restarting wifi which also works. For that thread search for "ksoftirq/d."

I have had the "stuck wifi" bug, but I'm not sure if it was happening the last time this happened. I'll check it out the next time.
There's no official firmware update on Kies for Norway yet, so I think I'll wait for one.
Had exactly the same problem and tracked the culprit - it was Fancy widget in my case. Removed it, installed Beautiful widget and all is well since
Sent from my GT-I9000 using XDA App
That might actually be it. If I'm not mistaken Fancy Widget had 30% battery consumption when I checked. I deleted it just to see if it would make a difference. So far so good.
Some details:
Fancy Widget will hit the 100% cpu on auto-refresh if there's no data connection available (either wifi or cellular). It seems there are 2 bugs with Fancy Widget; it ignores "auto-refresh off" option and it tries to connect to server even when offline.
A dirty work around would be to set refresh time to let's say 12 hours and make sure to manually refresh at least once every
That makes me even more convinced that Fancy Widget is the culprit. I usually have cellular network disabled (APNDroid On/Off Widget) to save battery and my wifi connection keeps loosing connection, probably due to some software bug in XXJF3 stock firmware.

[Q] Weird wakelock mmc0:0001:2

Under kernel wakelocks in better battery stats. Is anyone getting the mmc0:0001:2 wakelock? It has some serious counts an I think it's a culprit of some deep sleep issues. I tried with factory reset and not restoring anything, just installing bbs and its still there. I'm attaching a pic of insane 1.9 million counts. Anyone got any idea what this is?
EDIT: okay, so I did notice it was ticking like insane when I was downloading some games. And figured I would try turning off Wi-Fi, look and behold, it stopped ticking. Even when I turned it back on it back on it didn't tick up either. But if I turned if screen and later checked it was ticking again. My router had been acting weird lately so I made it forget it and put up a hot spot on my other phone. Now it doesn't tick up either, so must be my router D-Link DIR-655 with latest firmware. Good thing in getting a new router next week. Will update if it's better (going to buy a DIR-865L). Please do report if you are having same problem and find other solution though.
EDIT2: I left it using hot spot and awake time went up like 2 min and deep sleep 1.5 hours. Now it sleeps like a baby. Will update with new router next week. Hope this helps someone.
EDIT3: After a restart it started ticking up again for some reason even when connected to hot spot.

Galaxy Note 3 here. I'm getting the same thing, it's causing my phone to stay awake 100% of the time. I turned off my wifi and now the problem is done, but that is a huge hassle as I want to be connected to wifi all day if possible.
Will see if it's a router/modem issue or if it's a wifi on the phone issue.

Okay so, kinda forgot to update this thread, forgive me, Im a human I got my new router DIR-865L and I keep getting the same wakelock, however, this doesnt seem to make my phone to wake anymore, so I guess it was my old router, DIR-655 that gave the wakelocks. If you can try with a new router or at least another.
My Galaxy S4 LTE-A has the same problem. It occurs only when I connected to wifi.
Mmc0:0001:2 seems related to sd card, so I removed my external sd card.. but it did no trick.
And it is thought to lead to battery drain.
When connected wifi, battery decreases about 3% per hour, which is nearly three times to LTE.

Any updates/solutions? I have the same problem, it started after i rooted my LG G2. Unrooting/changing firmware/factroy reset or changing my router gave no effect
Same problem guys, I have this wakelock always.
Anyone has any solution for it?

I have the same thing now, wakelock detector app is showing it running hundreds of thousands of times with the phone only on for a few hours.

Unexplainable battery drain

For a month or more I'm facing totally unexplainable battery drain.
As seen on the screens below, the phone is awake, but it is not detected anywhere - not by android nor by GSam. In any case the battery draws faster.
I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

You have this problem
http://forum.xda-developers.com/note-4/general/explanation-horrible-note-4-battery-t3004274
I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...
@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....
Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.
All of the rest is done - I'm no newby

Oh sorry mate well I don't use much 3g so I can't help you there but if you're having drainage when you're using WiFi in general then maybe you should reconsider investigating the post above with the link I don't have so much drainage on connectivity with 3g or WiFi....viewing the pics you uploaded it seems suspicious.... Maybe an app? I don't know...

Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app
One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
