[Q][I9505] No deep sleep - msm_hsic_host

robogo1982 · May 18, 2013

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 don't have such an app. Wakelock detector reports no odd stuff.

Wakelock couldnt find anything on mine either I just had a feeling it was that app so I removed it and it started going in to deepsleep I also had a problem with maps keeping my phone 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.

Build number: JDQ39.I9505XXUAMDC

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

robogo1982 · May 20, 2013

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:

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?

robogo1982 · May 21, 2013

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.

fizzefazze · May 21, 2013

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.

What app was the problem?

I have a problem with this wakelock, use about 10-25% of battery time

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
