[Q][I9505] No deep sleep - msm_hsic_host

Hi everyone. I managed to get my hands on a beautiful blue I9505, had some issues while SIM unlocking it, but that's done and I am enjoying the phone very much.
Now, I do have a problem with it. The thing is, it simply will NOT go to deep sleep. Constantly hovering on 384 MHz with msm_hsic_host using a massive 90+ percent of awake time. It is driving me nuts. Our colleagues and friends over at Nexus 4 forums had an identical issue, and I read 57 pages of posts and used all their tips and tricks. Nothing helped.
Attached to this post you can see:
- the original Nexus 4 forum topic - [Q] msm_hsic_host - Nexus 4 forums
- The Google Code page where people complained about this - Google Code - Issue 41855 - "msm_hsic_wakelock" process on Nexus 4 causes severe battery drain
- my battery usage and BBS stats - attached to this post
- Qualcomm's fix for the issue - link 1 and link 2 at Code Aurora
I can't make heads or tails of any of this. The only thing that remains to do today (which I will do) is to flash a custom ROM and kernel for my I9505.
Thanks to anyone who will chime in to this discussion.

Bump - nobody else has this problem? Can you at least share your configurations so I can experiment a bit?

99% chance that some app you installed is causing the wakelock. Install BetterBatteryStatts to determine wich app causes deep sleep/wakelock issues.

I do have BBS as can be seen on the screenshots. I can't find the culprit since I believe it's the system itself.

I had this problem and it turned out to be avg pro app keeping it awake

clear dalvik cache and see again if it does enter Deep sleep or not, as everyone said its an application if not it must be a setting like sync, scan, or even that damn old wifi advanced settings that kept usual phones awake... reconfigure.

Insomnia
My phone won't sleep, won't time out and tapping the power button won't shut off the display. This happened just after deleting bootsamsung.qng, samsungloop.qng and shutdown.qng.
I'd replace the three deleted files, but they just grew and replaced themselves minus the carrier logo. The Baseband version now says: unknown. I stopped and installed google maps, that didn't help.
The good news is, those pink blocks are gone. The bad, I did a factory reset and noticed my cell network connectivity is gone. Maybe that's the sloppy work cutting down the SIM, or maybe something else? I've reinserted that sucker a dozen times and no joy. Do you know if the phone will stay awake without cell service? Putting it in airplane mode doesn't help.
Any suggestions? Thanks for your consideration.

Cleared Dalvik, will keep an eye out (though I don't know how can it help)...

Wiping Dalvik did not help. I will try a factory reset later this afternoon and let the phone be for an hour or so without any apps installed.

Same problem here, my msm_hsic_host accounts for ~99% of the wakelocks according to BBS, even when the phone is in airplane mode and Wifi is off.
I'm running stock MDC firmware & kernel, rooted though.

Read this about the wakelock, has to do with bad/lower 3g connections:
http://www.google.nl/url?sa=t&rct=j...3jjunrjohBvz3zaNvrYSO5g&bvm=bv.46751780,d.d2k

Thanks for the link.
This seems to be a logical explanation, but I've disabled 3G, and it still happens.
Plus it happens when in airplane mode, without any (cell) activity. I'm pretty sure that the kernel isn't configured properly.
Is there a known kernel / stock firmware version where this problem is fixed?

It appears that I have solved my problem.
I reset the device to factory settings and then restored apps, 5 by 5 in 30 min intervals. I still haven't restored all my apps, but so far I restored some 80%, here is the current state of things.

Very interesting.
Please keep us posted once you find out which app caused the problems, or if the factory reset fixed it.
Did you freeze or uninstall any apps?
Did you remove the T-Mobile bloatware?

I froze the same apps I had frozen before. If I find the app that caused the problems, I will report back. So far it's all good, 6h of use and I'm at 87% battery, wifi and 3G always on
P.S. I have Wanam's 1.0 installed
EDIT: 22h30 min, 2h4min screen on time, 48% battery.
I'd say that's an okay result.

You know what, I can't really say. Since the factory reset I restored all my apps and never had the problem since. Really weird issue. 25% can be bad. I had 99.4%

So, if I give you my app list, can you identificate what you used before wipe?
Maybe can will know what apps are potentially to reproduce the problem

[Q] Battery issues/questions

So, I've been having some battery issues lately and I can't really tell why. I haven't been doing anything too extreme, but my battery is almost dead within 12 hours of a charge, and the highest usage is mostly the Kernel and/or OS. I know next to nothing about that side of things, so I exported reports from GSam, and I'm hoping someone will be able to translate them for me if there's an obvious problem. Thanks in advance!
(I've also uninstalled Boxer, I only had it because Pro was free yesterday.)

Keep the location enabled.
Are you using any of the smart stay/air view etc. controls?
If not turn them ALL off.

As far as I know, location is always turned on (meaning I never turn it off myself). One of the first things I did was turn off all the smart crap, and turn off every piece of bloatware I could in the settings (I'm not rooted).

When was the last time that your phone was restarted?

I usually restart it every other day, give or take. It's gone a couple days without it before. I don't usually have it off for more than a couple minutes at a time though.

Did you install any apps recently?
How old is the phone?
Also do you have data/wifi on all the time?

That's not good. :-/
I install apps often, but I just as often uninstall them...I guess that's not much help. If it was one of them though, wouldn't it show up under the battery log?
It's approaching a year old, I got it last November I believe.
Yes, I keep my Wifi and data on all the time.

Bad network will drain your battery. Check how the signal is.

Android OS and Kernel are normal between 12-25% on 4.4.2. It's an issue with the battery reporting.
It looks like you've got a wakelock. 12% per hour means it's not going into deep sleep.
Check Wakelock Detector to see if it's going into deep sleep or not. (It needs root for everything else, but that still works.)

Stated in reply post that the phone is not rooted.
My advice will be to uninstall apps one at time to find the one causing the drain.

And neither is mine. Wakelock detector still works in the tab that shows Deep Sleep vs Awake. As I said by 'Everything else requires root, but that still works'.

That varies. At home, I have great signal (full-signal 4G, router is never more than 20 feet away). Some places in town, I can drop to 3G, especially my grandparents (although my grandma does have a router I'm connected to). There's a weird (unrelated?) bug where if I drop to 3G, I either have to turn airplane mode on or wait several hours until it reverts back to 4G, even though I'll be back in a verified 4G area.

I will definitely check that out and use it tonight. Thanks for the suggestion. I'll get back to you on what it says. What generally causes the wakelocks, specific apps? Or just poorly set-up preferences?

Usually apps. Facebook, Skype, some games. Although Mediascanner(Android process) is also known to be responsible for it quite often.

It looks like PayPal was one of the culprits? For some reason?
I did find out I could root extremely easily, so did so and downloaded Greenify, so I'm hoping I can tweak enough to get my battery life back.

That does seem to be the case... Either uninstall paypal or drop it in the Greenify list.
Google Search is probably either the widget or you're using Google Now.

I don't think they're related, but I can't be a hundred percent sure. You can try disabling both Google Search ones under apps -> all, see what that does to the info updates. If it scrambles them, just turn them back on.
(There's two Google Search, one is the search bar, the other is the app related to it.)
With that and Paypal dealt with, battery life should improve significantly.

Battery draining on stock rom.

I bought this phone few days ago and after some using noticed that battery drains really fast with WiFi/Mobile data. I downloaded Greenify and hibernated all apps using network. I turned off Sync, NFC, Energy saving on, screen brightness really low, gps, bluetooth still it drains with 2-4h using WiFi or mobile data(3g).
Can anyone think of something that drains my battery so fast? Thanks for any help!

Sounds like you either have a process that's preventing your phone from going into deep sleep, or your battery is malfunctioning. Try checking your sleep states with an app like BetterBatteryStats and see if your device goes into sleep mode properly.
P.s. My device lasts ~2 days with medium usage, always connected to the internet with either 3g or WiFi,and I'm not even using Greenify or anything similar, so the battery life is generally pretty decent.

Check the partial wakelocks screen. You should be able to locate the app that's causing the problem there. Also, I've read somewhere that cleaning the cache (either through Storage Settings or recovery) helps.

Well, it looks like that AudioMix process is causing your problems. I did a google search and found this thread that might help you.
Some have reported that disabling touch and lock screen sounds fixed the issue, while others said that clearing the cache did it for them. I'm afraid you're going to have to experiment

Thanks for the help! I'll try to fix the issue then.

Google Battery drain

Got my mate 7 A few weeks ago. Love it. Getting awesome sot (8.5) the last charge mainly using mobile data..
But today google contact sync is draining so much battery. I've exported and deleted all contacts from google. Disabled back up my phone in settings and even disabled the app in settings and it still opens... I don't really want to have to root it. Any ideas I may not have tried?

Also wonder,my phone is rooted though, well, didn't want to freeze any Google services but some features like backup system is stubbornly running even after disable in settings. Don't know any good medicine from this issue.

Yes I know that. The thing that drives me crazy is that I have no control over running background apps, like backup, that were disabled via Google provided interface. This is type of cheating to have an interface that doesn't do much.

I froze with TB google app, then defrozed it and converted to user app, also didnt enable google now service, after all I have drain 10% per 6 hours at night, while phone is on extreme battery mode and just laying on the night stand without anyone touching it.

How did you fixed it temporarily?
But the one million dollar question is: How much battery is lost while idle overnight?
This is the real question I think, because in all my tests, no matter the build version, I have got l least 5 hours of SOT (17 hours of use in total), which is not bad,
but most people get at least 7 hours SOT (in some 30+ hours) I guess I use it too frequently.
So, that would be the main question.
Please, do try to answer and tell us. Thank you!

I have already told it in this discussion, I have frost (later removed actually) google app system application, and fresh installed it from the market as user app.
As I said earlier though, now I use unrooted phone with locked bootloader, in completely original state (except I use tsf shell and disabled all unused system apps) and no longer have any problem with battery.

Heavy N4 problems, any suggestions?

So, my phone have been having a lot of heavy problems. This has been going on for a while and i'm not sure what to do. The problems include:
- Extreme laggyness
- Heavy battery drain (2-3 SOT)
- Random reboots
- Random freezes
- Not rebooting
- Only rebooting in recovery
- Dying at 30-40% batt, and bootlooping until I put a new battery (a fully charged one) or charge it
I have tried full wipes, custom ROM's and stock ROM's but nothing seems to work. Atm I'm running stock android 6.0.1.
Is there anyone having the same problems (or have had the same problems) and has any ideas on how to fix it? I have to 3.5 more months until i can get a new phone so it's pretty necessary.

same(ish) issues...
I have the same issues... And I'we also tried "everything" .
I am starting to belive that this has to be some kind of hardware failure... it seems like some use in a way eats up all the memory... I have also tried to stop all background processes, but this doesn't seem to have any effect. The problems happen on all ROMs I'we tried, so it cant be software... But I'm no expert...
One thing that seems to help is not using some google apps, like chrome, and hangouts... When I launched this app it just died right away, but after uninstalling them, it "lives" a bit longer...
glad for any help I can get...

Is there anyone having the same problems (or have had the same problems) and has any ideas on how to fix it? I have to 3.5 more months until i can get a new phone so it's pretty necessary.

I have the same issues... And I'we also tried "everything" .
I am starting to belive that this has to be some kind of hardware failure... it seems like some use in a way eats up all the memory... I have also tried to stop all background processes, but this doesn't seem to have any effect. The problems happen on all ROMs I'we tried, so it cant be software... But I'm no expert...
One thing that seems to help is not using some google apps, like chrome, and hangouts... When I launched this app it just died right away, but after uninstalling them, it "lives" a bit longer...
glad for any help I can get...

Disable app optimising in battery settings.
Use wake lock from app store and set to level 4.
☆Try a new battery☆
I had every issue you have listed... I replaced the battery with a new official samsung battery and it's been perfect since, not even a single reboot.

Had some ideas about the problem being the battery (I use an external charger) but to me it didn't make sense because I don't see how the battery could influence the software. You only had the problems with the battery or also the other ones (bootloops, lagginess, freezes, strange messages like 'sim card was removed')?
Thanks for your response.

Had all the same issues as you guys. The freezing, lagging, apps crashing and restarting at like 90% then boot looping until plugged on to charge. I tried all solutions, different roms, downgrading, completely stock. Bit it was the battery replacement that solved it finally.

No problem man, I honestly didn't think it would work at first. But I was suprised when It did. It's like a new phone

great!
edit: My most notable change was actually to remove the memcard.... As I'we read about the memcard issues...
It sounds so strange...
I actually tried some stuff for my self... Let debugging run and when it seems to get worked up, I'd just let it lie, I aslo tried tweaking the kernel, so that not so many background processes run at the same time. I'we had it running for about 18 hours straight! Last night I was browsing, installing apps and changing icons and fooling around with settings on 13% battery. Alarm worked this morning, and I'we been using it for more or less as I would use my s6, but a bit more patiently. At about 48% while running Instagram and play music it suddenly crashed. Now its up and running again.
Its still very clear that something isn't right and I will look into your battery solution...
Thax alot for you contribution! :good:

Here what I have done !
Hi dear !
I were facing this problem a month ago as my
phone gets reboot randomly as well as
shutting down by it self at 60 % !!!
Can you imagine that !
What I have done dear that I changed my
' class 4 ' microSD card to a new ' class 10 ' one as well
as I have changed the battery !
And you know what dear !
I have no longer facing this problem !
It had been resolved !
Now my phone is working fine since the last month !!
Hope it helps ??

Hi folks! I was having the same issues too apart from the battery drain. My phone was lagging, restarting, getting stuck on the 'Note 4' bootup screen. I reflashed and reset. Cleared Cache etc etc. But I also got a mmc_read error. Apparently it was an internal memory error. So I sent it back to be repaired as it's just under warranty. Looking on the repair status I *think* they've ordered a replacement mainboard and will be installing it. I'll also order a new battery when it comes back.

Can anyone recommend place or web site to buy genuine Samsung battery as 99% there is counterfeit ones?
Yes, bad battery makes your phone unstable. Had same issues on Note 1. When bought new battery all gone.
Thanks

Not all the problems are gone, but it definitely helped. Problem is that i bricked my phone now lol.

I think Samsung is to blame for battery problems,i use
Samsung Pro+ microSDXC 64gb class 10 UHS,after upgrade to Marshmallow battery went crazy,tried all 6.0.1 custom roms with BL and CP mentioned there,nothing the same fast battery discharging,went back to 5.0.1 perfect,next i went to 5.1.1 perfect ,back to Marshmallow same problem,now i use SimpLite v5 5.1.1 N910F....
Thank You Samsung !!
