[Q] "Shell" app eating my battery - Android Q&A, Help & Troubleshooting

Hey all,
My battery life has gone to sh*t in the last couple days, and I have noticed in my battery usage settings that the top contributor to its demise is always "Shell" (screenshot below).

Here are my specs:
----------------------------
Samsung Galaxy S4 AT&T
Cyanogenmod 10.2 (09/22/2013 nightly)
Rooted
Sometimes when I reboot, "Shell" does not appear for a while, but I have not been able to pinpoint what triggers it to start. I tried wiping and reinstalling CM, but it still shows up. The battery drain is so bad, in fact, that unless I use the original wall charger that came with the phone, the battery life still decreases while charging.
I am posting this in general Android questions because I literally have no idea what is causing it. It could be a CM bug, it could be an app I installed that's doing something malicious (Lookout doesn't think so, however), or it could be something else I haven't thought of. I just wanted to see if anyone else has experienced this on any version of Android and get some help debugging. Even if you have ideas for how I can pinpoint the app/service that is causing this, I would really appreciate it.
Thanks!

I am experiencing the same trouble with my LG Nexus 4 with CM 10.2 nightly.
Edit: Actually it was the case with 20131001, but it seems Ok with 20131007.

Yea pretty sure it was a CM bug. I reverted to stable 10.1.3 and haven't seen the issue since. I guess that's what I have to expect for living on the bleeding edge I haven't seen anything about it in the changelogs, but if you say it's fixed, maybe I'll try the latest nightly.

I have a stock Nexus 4 ROM (rooted, but still stock), and I'm seeing 76% in "Shell" today as well, so it's presumably not related to CM.

Stock Nexus 5 and I had 55% drain over 5 hours today... What in the world is causing this? Never had this problem before.

1 day old stock nexus 5 and I'm having this issue...
Here's my post from another thread with screenshots:

Anybody have a solution to this yet?

What version of Android are you on? 4.3? 4.4?

There is no official 4.4 for the Nexus 4 yet. I'm on 4.3, JWR66Y.

[Solved] S2 Network/Update issues.

So i recently got my S2 a few weeks back. before this had.an Optimus One.
I put my hutch sim in this one and for the past 1 week my bars keep fluctuating between 0 to 4.
Now i am on vodafone and my entire family uses the same.
Neither of them have a problem.
Also I never had a problem on my P500.
Also recently I had received an OTA of about 20mb, still on ICS though.
After that update I have been getting random freezes, cant change lockscreen wallpaper, not even with quickpic. TwWallpaper keeps crashing and this signal trouble.
Adding a few screens.
Taken on the same spot. Also right now my sister is getting constant full bars!

So i was wondering what should I do?
1. Replace my sim?
2. Visit a service center?
3. Rollback the update, if yes, how?
Also I'm on Stock, non-rooted. ICS 4.0.4.
SGS2, send this you must!
Given it's a new phone, your problems have been caused by a carrier pushed update & your warranty is still good, the 2nd option (tho if it were me I'd probably mess with it anyways because I don't really care about warranties).
Re: S2 Network/Update issues.
So most probably its a software issue?
If so I guess I have my reason to root and install a recovery coz even I couldn't care less about warranties..
one thing though, like my P500, once rooted, the root can be reversed as well, right?
Also is there any way without root to rollback this update?
SGS2, send this you must!
Re: S2 Network/Update issues.
Hey vj the signal drop problem is a common issue on Vodafone network if you want you can try to change your s2 modem to see if will gonna improve your signal .
Use this thread http://forum.xda-developers.com/showthread.php?t=1656005
Or you can try to root your phone using this method that I used http://forum.xda-developers.com/showthread.php?t=1501719
Then you can try another Rom

thanks man!
I switched to GSM only since 3G plans are way expensive here anyways, also since I'm on wifi usually.
And haven't seen a drop since then, hope it stays so!
Also network issue aside I sometimes find the metal around the camera getting hot while gaming for more than 30-40 minutes.
Is it normal or should I go ahead and flash that modem, since it boasts of nominal temperatures at all uses?
And OT, are you also an ex-P500 user? I seem to remember you seeing around on xda. And I have been on OT & P500 forums only prior to SGS2
that heat is a normal effect for our s2 when we play a game or a movie and if you gonna flash that modem your phone signal will gonna increase and the heat will lower (tested by me)
OT : yes i'm an ex p500 user you'll gonna see some work for it in my signature and an rom port (not in my sig )

[Q] Potential GPS fix for P769?

Hi all,
I am currently using AntonX's unofficial CM11 for the P769, and its great except that like CM10.2 seems to be broken. In CM10.1 it worked perfectly and same with the stock ROM as well. So I decided to pull a few files from the stock Jellybean ROM and create a flashable zip that installs the old files that have to do with GPS. It seems to work pretty well as I was able to get a pretty good fix from a cold start in less than a minute using device only location settings, but it doesn't seem to work nearly as well as CM10.1 and stock. Does anybody have any ideas on how to fix this problem (I have already tried using different gps.conf files to no avail)?
Attached below is a screenshot of my latest GPS fix in less than a minute and the flashable zip that I created.
Thanks!

I think your files are the same as the ones already in the ROM.
What's wrong with GPS in CM10.2 or CM11 anyway? It never fails me, I always get a fix within a minute, even on a cold start.
As far as I remember GPS in CM10.1 was a little strange. I think I noticed that sometimes GPSTest was showing yellow bars but accuracy was in hundreds of feet, which actually indicated not a good lock. I may be wrong though, been a while.
Still a Problem

Yeah I think you're right that they're the same files because I was testing GPS again today and it would lock for maybe a second and then if I even moved, it would instantly drop. But this problem is definitely here because on CM10.1 and stock I would instantly have about 13-14 satellites in view, and be able to lock to about 7-9 of them in seconds, whereas now it takes about 1-2 minutes to get 10-12 satellites in view and lock to just five which instantly lose lock when the device is moved about 10ft. This is using the device only method of getting GPS so there is no use of wifi or cell signals to get the location because I have very spotty coverage. I just wanted to point this problem out as I've noticed it on other ROMs too such as BobZHome's CM11.0 and leolawliet's PenberRom5 which is also based on 10.2. Other than this little problem the ROM has been great and I thank you for your work AntonX!
On my P778g, i also noticed a diference between CM10.1.3 and CM10.2/CM11. But after some testing comparing to stock (my father has another p778 with stock rom) i discovered that the only diference is the signal strength: Under a clear sky the GPS works exactly the same but inside a house the roof is too much and the signal seems to be too weak, so it takes a lot more time to fix compared to stock. Keeping in mind that i never use the GPS inside my house this is not a big deal after all. I bet that no one is testing the GPS outside... try it.
If it wasn't winter and I paid my phone bill I'd be happy to go out now and test the GPS on my p769. I'm running omnirom tho, and I don't think it's cm based so I could have different results.
I'll post back here when I get a chance. By the way, the GPS on AOKP wasn't any better.

KitKat wakelocks issue

Hi guys!
I usually use a 4.3 rom because of this issue but every now and then I feel like flashing a 4.4 rom just to see if it it would go away.
So on every 4.4 rom i used i got crazy 3g related wakelocks. Is anybody experiencing a similar problem? Here is a photo of BBS:

Thanks to it I've got ****ty battery life (14h tops). I have also tried disabling fast dormancy with this i9300 market app, but it didn't seem to help.
Is there anything I can do?
1. How old your battery is?
2. How much battery life you used to get on 4.3 with similar usage?
3. Which kk ROM you have tried?
4. What was the SOT when you took this screenshot?
1. I guess it's maybe 1,5 years old. I don't expect miracles, but battery time now is patethic.
2. I could reach like two times more, 25h from 100% to 0% with 2h SOT.
3. CM11, SlimKat, and now I am using PAC.
4. I don't remember exactly, but 1,5h tops
Hmm.. looking at your information i can pinpoint it to the 3g wakelock only.
I am finding this on github-
svnet-dormancy / multipdp
Author(s): sven, credits to Entropy512 @xda-dev
Ranking: n/a
Speaking Name: svnet-dormancy / multipdp (those are synonyms, depending on android version)
Rationale: svnet-dormancy is a kernel wakelock related to cell data transfers - Fast dormancy or not, you get a 6 second wakelock any time the radio transfers data
Know actions: Change the duration of the wakelock (use at your own risk). Reduce the wakelock by reducing the amount / number of data traffic requests
Known conditions of occurence:
Caused by data traffic
I am unaware of a solution for this. Maybe someone else will be able to throw more light on this. hang in there.
I'm having exactly the same problem as you, those 3 wakelocks(multipdp, secril_fd and l2_hsic) are killing me. I tried to change ROMs, kernels, radios, but couldn't get rid of them.I've done a lot of research, but didn't come up with the solution for this. I even tried with neatrom, jb version, which is closest to stock, and I have those wakelocks there too.
Any luck?
Hi sheo,
Did you found the root of this problem?
I have the same situation, all kitkat roms I've tried so far (including CM, OMNI, SlimKat and lots which I don't remember anymore) have this wakelock problem.
Some users at the better battery status have tried to help me, but all they suggest is to turn my smartphone in a dumbphone by disabling/uninstalling everything that makes sense to have in a smartphone!
So, (sarcasm=ON) without removing, facebook, google play services, google plus, disconnecting from wifi, going to 2G and dimming my display darker than a black hole, (sarcasm=OFF) were you able to use KitKat on your I9100?
Thank you! :fingers-crossed:

Unfortunately, no. I have changed my phone since then, and the problem lasted until the end.
You'll have to learn to live with it.
I did.
Not an option...

Not an option... It stays hot all the time and can't live without a charger for more than 8 hours even without use...
I just switched back to stock rom from my carrier (Brazil Vivo), as there is no wakelock but it is killing me with slowdowns, glitches, bugs... And that sense of using a 2011 (amazing) phone!
I'm just preparing to install SlimSaber Reborn and came to this threat to check for some hope.
See ya!

you will have battery drain but not much.atleast you can get rid of the random reboots and enjoy the rom.I am a moderate user so i am getting around 15 - 16 hours of battery..

because it always keeps the cpu active,phone just doesn't goes into deep sleep,so that's how it affects the battery life,
but yes on the other side there wll be no reboots.
I was just wondering, then why not lower down CPU freq every time you sleep your phone? As in, lower it to most lowest freq. Yea it won't go to deep sleep but at least no random reboots and battery drain.
Since I don't have this MI3 as of now, you guys can try by installing SetCPU and do some profile settings.

I've noticed the same issue. Originally I've set it to only turn on during night time, but now it stays turned on, disregarding my time schedule.
Actually the new Android 11 upgrade is not stable for the time being, that apps may not cope well with it (despite Samsung claimed otherwise in the update changelog). Some games performs even worse than on Android 10 with one of my games crashes 9 out of 10 times just trying to enter the main menu...
So I think it's better to hold off this upgrade until the major issues can be addressed. I upgraded to this mainly to hope this might help with some touch-related issues I'm having with previous versions, and am now very disappointed as the tablet feels even worse than before :-(
