Kernel wakelock lli_cp_wlock - Samsung Galaxy Alpha

One day phone started to lose battery. Using betterBatteryStats I've found that it is caused by kernel wakelock lli_cp_wlock. It appears without any pattern and I can stop it only rebooting the phone. I've tried to reinstall the system and flash newest firmware, but it hasn't helped. Searching the internet I've found that lli is low latency interface controller which is connected in some way to the modem. Any idea how to deal with it? samsung g850f android 5.0.2 stock rom
P.S. sorry for my english, it is not my native language

Same problem exactly here. Doesn't anybody have any clue on what a solution would be? This "lli_cp_wlock" wakelock comes and goes wherever it wants.

Try to turn off functions or apps that use GPS/location or background syncing,
and turn on GPS/location manually only when you need it.
Functions that use GPS/location like:
Google Location History
My places/Find my phone
Google remote control
Samsung remote control
GeoLookout(weather notifications)
Weather syncing(use current location)
Just check everything in settings/Google settings and turn off those you don't use.
And social networking/messaging/email apps would background sync
or check for push message regularly,
try to turn off sync or turn off app features that use locations or uninstall them
and see if there's difference in battery usage.

All these are done from my part at least and more. Nothing happens. It is not an app problem, it is an Android System battery drain.

I installed BetterBatteryStats_xdaedition_2.2.0.0B5 as a system app,
and here's what I've noticed so far:
The percentage in "Kernel Wakelock" is percentage of time,
not percentage of battery usage.
My percentage of lli_cp_wlock is less than 1%,
so if your percentage is high, it should be related to some apps.
The percentage of battery usage is in "Process",
check here to see what apps drain the battery the most.
The percentage in "Alarms" is percentage of wakeup counts,
have you checked the numbers here?

Sudden Battery Drainage

I understand all these battery drain issues that the prime has been having but haven't actually had them, until now. I used to lose about 2-3% overnight but suddenly I am losing around 15% because it won't sleep. I go into the battery setting and it shows it been awake the whole time. Now I am sure if I looked around I may find a fix but it just seems a bit odd that it has just suddenly occurred. And its not a wifi drainage issue as I usually put it to sleep at power saving mode and wifi off. Just asking why?
Thanks,
I think it could be the Asus weather widget which I had set at 1 hour refresh rate.
if this just recently occured out the blue, likely a rougue app or something you recently installed. an app running in background or sync is likely the culprit.
Just put Skype on it but that's not signed in most of the time
every android tablet and phone i have does this occasionally, and those occasions are when i either play video or music. some of these media players employ a wakelock that will not disable after you put your device to sleep. sometimes a reboot will work, sometimes not. most of the times the reboot keeps it from draining. even force quitting all my media apps wouldn't work.
so basically i reboot every time i use any type media player so i don't get the drain - netflix doesn't require it, dice and just about every music player does. i'm not sure it this may be your problem, but it may be a possible solution.
I find that making sure to check the last two settings under Asus Customized Settings helps this. I was waking up in the morning to find my dock dead everyday before I checked those two settings. The only down side is when I turn the screen on and wake it up, it takes about 5-10 seconds to connect to the wifi. No biggie.
Use better battery stats and see what is causing it. I have read that skype does drain battery pretty bad. And even if you're not connected it still runs in the background at start up. Another app I would recommend is Autostarts. It allows you to disable apps at start up. I know system tuner is free and has the same functionality but I find Autostarts better. With ST, you just disable the app at start up, with Autostarts you can disable it at start up, shutdown(which some apps fire when the tab is being shut down and other system events), also other events. Like some apps fire up when you get a text, or when your connection changes etc.. I just think Autostarts has more options.
Also dev Entropy has a thread in the GS2 forums about know battery drainers. Some of it applies specifically to the GS2 but there are a bunch of general battery killers listed
http://forum.xda-developers.com/showthread.php?t=1308030
If you go to setting and battery it should show you which is using the most battery. The first one on top. If its android system, you can click on it and it will show you a list of whats been using your battery which may point you to the culprit. In my case, media was the only thing in the list. And I know if an SDcard is inside my dock it will drain battery. So after removing it the drainage went away. Havent had the drain issue since. Again yours might be different so check the battery usage.
Thanks for the feedback guys, the first thing i am gonna do is charge it up after it fell flat right up to 100% then try some suggestions. I am thinking a reboot could help it.

Problem with S3 Battery

When i fall asleep i just place my phone nearby the bed and its on airplane mode,wifi closed,data closed and generally no apps running(i think so).The battery is level (ex)50% and when i wake up,about 7 hours later its always about 15-20%.why this happen?
I checked the battery manager just after i waked up and the first was screen(56%) and after that adobe reader(10%)

Better battery stats does not work.dont know why.and i made my own post cause i cannot find the solution of the problem on other posts.try to be more polite to your answers
have you tried downloading the xda version of the better battery stats? if not here it is
http://forum.xda-developers.com/showthread.php?t=1179809
Is your phone rooted? Like others said, try to install the xda-forum version of BBS but it's weird because I did install the one from GPlay.
One of the first lead is the WiFi? Is it always turned on? There's a bug with it. Go into the advanced WiFi settings and set it to 'only if activated' (I don't know the exact spell in English but it's something like that).
But you better have to dl BBS & check the wakelocks.

what?
Underclock when you're not using your phone.
That will save battery.
If ur using stock TW. Put on power saving mode
PM Me if u want to know more.
Try using an app called easy battery saver and only use the cable and plug that came with your galaxy s3 it works for me, today I had eight hours after charge and using internet with 3g nearly continuously.
You would get much more by leaving it on standby.
Also restrict your background data, turn off your automatic updates at play store andturn off WiFi while screen is asleep.
Follow all these for better battery.
Use any battery investigation apk/widget (I'd recommend battery monitor widget) and look what is causing the drain...
may I guess: cell standby or gpsd?
guys i remember you that the cell phone is on flight mode with wifi,gps and data turned off
and, if you have a soft which contains a bug - you'll have such processes running.
It is up to you to install any apk which will contain more detailed statistics what actually is consuming so much juice.
If you do not want - no one would force you.

I have the exactly same problem,30% drain overnight.That happens after updating to 4.1.1 JellyBean.With ICS never happened.
Go into the battery page, click on the graph and then post a screenshot of the detailed graph here. It is usually an app or process not letting the phone go into standby. Happened to me when I had my phone on ICS out of the box. I fixed that all up through the individual app settings and all was sweet. Then when I went from ICS to JB, the issue came up again and I had to go through the apps again to change the settings back. It seems that by updating from ICS to JB, certain settings get set back to default, which then does not allow the phone to go into standby.
Culprits that I have found are:
Facebook - set to manual refresh interval
Weather (or any weather widget) - manual refresh interval
Google play store - Turn off Google AdMob Ads
Any form of newsreader (I was using Pulse) - Turn off notification when there are new stories
Wifi advanced settings - Set Keep Wifi on during sleep to "Always"
Samsung account - Turn off sync
Samsung app store - Turn off Update Notification, turn off push notification, turn off ad preferences.

Maybe some apps running in background if you are using *viber* delete it
It makes proximity sensor always on.
Try delete apps like that

Guys please keep in mind that keeping the stock os without any custom kernel might be not as effective than using an adequate custom rom...
In addition remember, cooler temperatures cause ur battery to lose its charge faster...
So if ur phone is placed on the window shelf and its getting cold during the night it might cause ur battery to drop fast..
I made this observation with my sgs plus....
Hope i helped.

[Q] S3 Battery drain

Hello! I bet you have seen this a heap of times. Well guess what, so have I. Alas, nothing has been found - I checked Android Central, the T-Mobile and AT&T websites and all sorts of other techy places but to no avail. So here I am, scavenging information, doing stuff to my phone - I am finally to the end point - writing a post myself.
So, heres my problem: awful battery and when I charge while using the phone, the battery goes DOWN!
Lets start with this
What I have done:
Factory reset
Cleared cache
Deleted every program (app)
Airplane mode
No sim card
Downgrade to 4.1.2
Rooted and calibrated battery
Full discharge to full charge
Now please check the eye candy down below in the attachments..
So.. What else?! It isn't a hardware problem because when it is turned off and charging, it seems to be fine.
Some system specs:
Galaxy S3
International
OmniRom 4.4 (btw, this ALSO has drain, I install hoping it wouldn't)
Wrong section just post in q& a section...
Install BBS and see what's eating your battery..

Go into Google Settings and Turn Location Reporting Off. If you want a more agressive power saving go into WiFi settings and turn Always Scanning Off.
Clean
I had this problem of the phone discharging while charging (no pun intended) and the only solution I found was to clean the phone's USB charging port with an Contacts cleaner Spray (the one that has a "pipe/tube", let it dry out and clean the usb plug likewise. That solved my problem. But mind you: my problem was phone discharging while charging

Thanks for the info. I did both, yet, noticing a little less awaking, it still drains when charging and rather abnormally when not and just using it. The only thing waking my phone up now seems to be Google Search? (in wake lock detector) Cant anyone explain that?
Install an app disable services and disable Google services which are active in background... But disable then one by one as it may affect your play store functionality...

using wake lock detector I noticed the apps name (google search) was com.google.android.googlequicksearch... but, using a service disabling app, I couldn't find that name under the system app ''google search'' tab?
*EDIT: I tracked all the wakelocks (ALL of them) and they lead to location services! Simply turning it off gives me no more wake locks. Not a permanent solution as I am completely unsatisfied, but a temporary one nonetheless. Going to keep monitoring battery as it seems to be fine, but I haven't nailed down the discharg while charging problem yet...

Device is always awake and WiFi is always on

Hi,
I'm having battery issues with OPX again, first it was a faulty battery, but now it looks like the there's something wrong with the settings. The device loses about a third of it's battery overnight, but when I look at the stats I can see that WiFi is always on and the device is always awake!
I have installed naptime as well and told it to ignore sensors (not that it matters as the device is not moving overnight) and to sleep even if connected to a charger etc. No matter what I try the device is always awake.
Is there a way to find out what is keeping it awake?
When I look at usage since last full charge there's nothing unusual there, just regular apps and single digit percentage numbers.
Thanks for your help!
System version?
I'm on Android Marshmallow, using Resurrection Remix ROM.
I'm not quite sure how to use the wakelock blocker, but I just installed Wakelock detector and it shows TripAdvisor as #1 on the list. I have it blocked in notifications, but I can't find anything related to TripAdvisor in wakelock blocker.
Is there any way to prevent apps from keeping the system awake, or should I just unintall TripAdvisor completely?
Not sure if I'm on the right track, but something is keeping the system awake and I need to find out what
OS3 with google back up turned off I get zero drain. Maybe 2-3℅ max over night. Also turned off automatic updates playstore. With just those two things off dont see drain anymore might just be lucky.
Well I think I'm back on normal drain. I uninstalled TripAdvisor, not using it except when I'm on holidays. I disabled the option to keep WiFi on even during sleep.
I used wakeblocker to block all weather/facebook entries, and I have two gmail accounts, one which is use a lot and one which I don't - so I blocked all wakelocks from syncing the account I don't use often.
Battery history confirms device is now correctly going to sleep and turning off WiFi. Automatic updates are still on.
I probably blocked too much, but I don't care anymore, I have 30% more battery every morning and that's good enough for me

[TIPS] Fix That Weird Battery Drain On Any ROM {M/N/O/....Z}

Hi guys, this is not the thread where you'll find fancy kernel tweaks to improve battery. I'll share a few little things I personally follow that considerably improved battery life for me. You don't even need root
If you use any other battery saving placebo like greenify or wakelock blocker, then you're on your own. I don't recommend these
Follow each of these steps -
1. Turn OFF pocket detection, screensaver and ambient display.
(AD is upto your preference, doesn't drain battery much)
2. Set location to device only mode.
(DE mode uses GPS satellites and gives enough accuracy, high accuracy mode keeps bluetooth and wifi scanning on, draining battery)
3. Turn location permission off for google app.
(drains alot of battery)
If possible disable location for every app except maps and google play services.
(tracks your device when it's lost)
4. Go to location settings, scanning and check whether bluetooth and wifi scanning are off, if not, turn them off.
5. Go to battery, performance and turn off automatic optimization.
6. Most important step, reboot your phone after doing all this.
That's it guys, try this and report Suggestions are welcome
Good Tips.
Very nice

I have done all these except 6 point (once per day). Plus I have installed greenify. But still battery drain in most of the ROMs. Even if I won't use my phone, the battery is draining fast. I have turned location off (always)

Just try that bud
actually the thing is that kernel is not proper for any ROMs for which there is a battery drain...
changing kernels will be battery saving because of CPU tweaks running always in the background even if the device's screen is off...
use greenify in magisk for more if you dont want to tweak with your kernel...
do this and tell if your battery drain is solved... also follow these steps above.. they are mandatory as well...
it doesnot work well for resurrection remix ROMs... i have tried... maybe fixed by change in kernel tweaks...
For some weird reason my device doesnt go deep sleep anymore. The battery graph use to to be flat but now therea a slight steep when i am asleep. I still do my usual habit of turn of wifi, turn off location, turn of sync, turn off scanning for bluetooth and wifi, turn off locatiom history. I am on stuart's los 14.1. this started to happen two days ago. You know the best app to troubleshoot?screen and lineageos system and android is on top of battery stats when checking after waking up overnight.i have no addon or other tweaks. Not even greenify because battery graph overnight is flat before.

Where I can see you're doing wrong is turning things on and off. The steps mentioned in thread do not break a single thing. Keep location as device only mode forever (no on off required).
Just follow those steps for atleast one cycle and report

Ill try. Ive been doing this for a long time since teammex releases builds. And since the first build of stuart got no problem up to the second build.by the way i am.only turning on location once in awhile if i need navigation. Only wifi and data connection is frequently turned off and on. The rest is off 90% of the time

Battery drain issue
Any one having a battery drain problem ........Go to magisk( if not installed plz find the tread and do it)....Then download Enable Doze ..... Optimize Google play services and Google app and see if it is fixed......Worked for me
Very nice practical advice. However, greenify is not a fancy placebo. Together with Leandroid, and only following no.1 and 4 of your guide, battery almost doesnt drain at all on my snapdragon Xiaomi when idle. For my MTk xiaomis, I have to flash the drain fix in addition to get the same results as the snapdragon variants.
Anyway, good advise.
