l2_hsic wakeups - finally getting rid of it

i posted this in the Note section since it had a big thread going about this wakeup annoyance called l2_hsic, but as i am using a S2 i should post this here as well (you may remove my posts there if you think 1 is enough, i have no permission to do that yet), its a wall of text so im just gonna quote it:
i too had alot of battery drain without actaully using the phone much, was reaching aorund 2 weeks on stock 4.0.3 but the performance wasnt all that, so i installed Supernexus & DorimanX (extreme_battery), great performance but the battery wasnt really what i expected, barely a week with low usage, tried lots of things while i searched a ton of topics about l2_hsic, using gsm-only with FD disabled, turned off play store notifications in the store itself and market updates in TB, WiFi is only on when needed, data usage is disabled, so is gps since i dont use it, baseband/ril is matching, and disabled stuff in TB/gemini/LBE which i dont use, battery got a tiny bit better but far from the 2 weeks i was reaching with stock (had alot of stuff/bloatware frozen though), i was even thinking about flashing stock again but that was gonna be the last option, performance on custom roms was far better
so it got me thinking, saw alot of l2_hsic wakeups with no appearant reason to why or what was triggering those while i had just under 1%/h drain with all that stuff off, then i remembered the last time i opened the play store before flashing Supernexus & dorimanx it didnt work, probably froze too much in TB but didnt want to get to the bottom of it since i was gonna flash a new rom & kernel anyway
so a couple days back i decided to freeze google play store/services and market feedback agent in TB and block them as wel in gemini (had a hunch they could be the culprit triggering all these wakeups since some autorun lines automatically re-enabled themself after turning them off in gemini, one even was called WAKE_UP lol), denied all access in LBE and then used the phone as i normally would (occasional WiFi, couple calls a day and thats it)
rebooted the phone a couple times the last couple days to test if it wasnt a 1-time-wonder but things stuck and im glad to say im now at 0.2%/h of battery drain in deep sleep, up to a max of 0.5%/h when in use, down from around 1%/h in deep sleep, so it will probably last a bit longer than the stock rom/kernel would have before, great success!
before i froze the store/services/agent i had around 1500 wake counts from l2_hsic on a couple of hours while the phone was in deep sleep, now im at a couple wake counts on almost a day while actually using the phone like i usually do
now, in case i need to go in the store i just have to enable the stuff again in TB/gemini/LBE, little effort imo for alot more battery life

in case youre wondering if my post was full of of crap when i said disabling the store doubled my battery life:

notice the l2_hsic wakecounts are now 16 on a week, where i had a couple thousand during a few hours of deep sleep before i disabled the store/services/agent, this is the stock battery with Supernexus + DorimanX (extreme_battery) on 2G, wi-fi wasnt on this week, and i only make like a couple short calls a day, same as ive always done, yet the store woke my phone up so much i barely reached a week with a full battery before disabling it

TLDR: in a nutshell, after trying all possible solutions to get rid of the thousands of l2_hsic wakeups (in deep sleep that was), it was actually the google play store/services(/agent) that caused it, disabled it, and i have more than doubled my battery life
obviously most people use their phone alot more than me, i make a couple calls a day, rarely turn on wifi and thats it, someone using the store on a daily basis is probably not gonna disable it and reenable it over and over, just wanted to point out how much the store actually drains your phone without wifi/data in deep sleep on a 2G network

It's a pity that gmail/youtube wouldn't work at all after disabling google play services, google play store and market feedback agent.
The data/wifi signal that would usually turn blue stays grayed out. I'll be trying enabling just play services

Interesting, it would be good to see this bug fixed but Google apps remain connected, especially Gmail

and after a couple months the l2_hsic evil is back for no appearant reason, i hit up TB one day with half a battery and it couldnt find the pro key again, so i closed it and thought i'd ignore it, next day i turn the phone on again and my battey is near empty, wtf? enabled google play stuff again, updated my apps including TB, pro key problems solved, disabled the google play stuff again, no luck, l2_hsic is back in full force, disabled all the google apps, no luck again either, but i noticed umts_ipc0 was in there too with just under the amount of l_hsic wakeups, which has something to do with the usb, so i started looking further and it seems a fix for the l2_hsic wakeup bug has already been found, even though its on another device:
http://forum.xda-developers.com/showthread.php?p=41338478
only problem now is to have the kernel modders take a look in their kernel and see if that bug is present and if so, if they can fix it?

sorry mate its wakelock detector

I am suffering the same problem, and it drives me nuts
not a user of music, video or things like that
for me the troubles started with the last update from 20 November
without using the phone, the battey drains in 9 hours, not installed any third party apps
Android OS kernel 52% , Android system 9,8 % Media 5 %
I contacted samsung for a couple of times, and only give the basic answers
already wiped cache, several times, re installed the stock firmare two times, MJ7, nothing helps
i am getting really sick of this and already looking around for another phone
Kind regards, Wiebe

Have you tried to stop comm/sync stuff? For instance disable the sync toggle? Or both Wifi and Mobile Data when you do not use that?
Have you tried wakelock detector to see what keeps your CPU from entering deep sleep state?

What eventually fixed mine was a complete wipe, then reinstalling stock. (I have since gone on to a custom rom again and custom kernel) - my Android OS/System sit on 3-6% average now. Where as previously they were sky high.

IT IS A KNOWN ISSUE!
This thread will help you optimize ur battery - http://forum.xda-developers.com/showthread.php?t=2579075

Don't confuse the percentage in settings for the actual drain percentage. It just means that of the ACTUAL drain, 20% is done by OS. So 20% of for example 4% per hour.
Use BetterBatteryStats and Wakelock Detector (both can be found in XDA) to find out what is really causing it.
My Android OS and Android System are also both at 20%... But I still only lose 0.1% in deep sleep.
And in the past hour it went from 96 to 93%, with screen at 100% brightness, Wifi, tapatalk and music. So....
Send From My Samsung Galaxy Note 3 N9005 Using Tapatalk

Again.... It's a known issue. There are many Threads about AndroidOS Bug and the Deepsleep Problem.
Just search for it or read the last few days in this forum.
Every day a new Headline for the same Problem and in 95% of all no App is the Problem for the battery draining.
If you use your Phone not often, and your Battery lose 2-4% per hour, AndroidOS is on top of your Battery Status list and everything is fine.
If your Battery need much much more per hour, and AndroidOS is also on Top check the wake time from Display and AndroidOS.
This is okay

Battery drain edge plus

hi, everywhere i've read all over the internet seems to me that no one has actually a clue as to why samsung phones are using a lot of batter..ie my galaxy s6 edge plus on uk vodafone..100% in the morning need to recharge it again at 6 or 7 oclock with light usage...lots of people are having similar issues with samsung devices, all saying its the android system or android os using it as you can see that when you go into your battery settings, beyond that its all mystery...then you get ....turn this off, disable that, power save that, get wakelock detector, task detector. Phoned samsung this morning they said it was the battery...oh dear me...they would replace it for me, i would have to be without a phone for a few days...that was their answer....the phone is 2 months old with light usage, had iphones in the past, not one problem, since android, im now paranoid in making a call and sending a text incase the battery dies...you shouldn't have to disable features on a phone that was made for that phone, there is clearly a fault in the software, so im asking the super experts here if they can actually pin point the problem thanks, its happening a lot, so there clearly must be a bug in the system software somewhere...and its not my apps, only got half a dozen installed, and i ve reset, cache cleaned, reinstalled one app a time, tried it with no apps installed, always the same...android os or android system between 12% to 87%...thanks to anyone that helps

I'm having the same issue. Last week before the 6.0.1 update I rooted my S6E+ and it started going into a boot loop. So I put stock rom back on again and left it. But the battery is terrible since. I thought the update to 6.0.1 would help but it's the same. At night (10pm) I'd put into airplane mode at 100% and by morning (7am) it would still be 97%. Now in the morning it's 43%! It's losing 57% overnight in airplane mode.
Any help really appreciated!

If factory reset didnt help you need root . This is the only way to fix it

I aware you have trip the knox and that cause Doze fail to start when it is on idle.. Please check your knox via Phone Info *Samsung* via playstore and if it shows 01, that means the knox is tripped..

By placing the root, leaving the stock firmware the device does not go into deep sleep and then consumes the battery.
You must flash a kernel for MM

Battery drain is caused by a lot of factors. The truth is that there are a lot of apps/services on your phone that you don't actually need/use. Google for example tracks location, syncs your account, backup, etc. All these services are running in the background and eat up juice. Android is different than iOS, so you need to disable some apps/services that you don't need to prevent them from running. There's also a lot of apps that have the "wake up phone" permission enabled or "keep phone awake", that even though your screen is off, will sync and do stuff. There used to be a method in Lollipop to prevent an app/service from waking up your phone, but I can't find it in Marshmallow (yet).
I'd recommend to root your phone, install TitaniumBackup/Package Disabler/etc. and freeze all apps/services you don't need. Search for "debloat" and you'll find loads of lists that you don't actually need and can disable.

Thanks guys for the help. Can someone give me any pointers (link to forum) where I can update my kernel or root please? Really appreciate all the answers thanks
I am back to 5.1.1 now and rooted.
I've noticed my phone is now downloading the 6.0 update again. Is it ok to install this or will I lose root again?

Where ever any help for battery asked everyone says disable this and that.
There is some kind of software bug.
I really regret now for buying this device

Battery Drain
I am also facing same issue tried moving to custom Rom performance is awesome though battery drain is something i am not able to understand .Even i tried keeping phone on airplane mode still battery drain .Maximum standy i am getting is 9 hours after light usage .
Any help will be really appreciated .

Install a custom kernel and rom, flash exposed framewrok and install Greenify, Coolify and Amplify. That's how i minimized the battery drain.
I recommend the Audax plus kernel and rom.
You'll find it here with a detailed guide: https://forum.xda-developers.com/s6-edge-plus/development/rom-audax-plus-v1-0-t3219017

There is no root available for the at&t varient

You know.. it's such a shame.
I loved my phone but I'm not keen on doing Samsung again. My battery life was horrendous.
Greenify and Disabler Pro h help a lot but not enough.

i think i got the same problem. i rootet my Samsung Galaxy S6 Edge+ (SM-G928F)
After i saw that 7.0 was on the way for the s6 and s6 edge i unrootet so the phone was ready to get it OTA.
But after this it´s using around 40-50% over night
First time i unrootet i used Samsung Smart Switch to get back to stock.
I then rootet and aplied a Deep Sleep fix wich help
But now i want to sell the phone and would like to sell it stock and from i can see it looks like the problem is still there.
This time i flashed the phone via odin and with this file G928FXXS3BQB1_G928FNEE3BPI1_G928FXXU3BQA5_HOME.tar.md5 from sammobile.
I hope someone can help me out to if there is a fix so it get´s deep sleep in stock.

Don't get any phone with small battery. Like 2K resolution with 3000mAh is a bad idea. Galaxy s6 edge+ Plus should have 4000mAh battery instead.
Get Galaxy A5 2017 full HD screen but you get a better battery life.

Nougat wreaking havoc on your battery? Solutions...

If you're reading this, you're probably regretting taking the latest OTA update.
It seems that Google hasn't been so kind to our batteries this time around, and with no root is in sight (thanks AT&T), our likelihood of any real battery life improvements is severely limited. Here are a few tips which may help remediate the situation.
Don't drop the soap...
Suggestion 1.) Reset app preferences. This may help to sort out some battery draining bugs:
Navigate to Settings>General>Apps>(dropdown)>Reset app preferences
Suggestion 2.) Disable all AT&T & LG bloatware. Less apps to run = less potential battery drain:
Navigate to Settings>General>Apps> disable everything you don't need
Suggestion 3.) Force GPU rendering. This will take some load off of the CPU which is more power-hungry than the GPU:
Navigate to Settings>General>Developer Options>Force GPU Rendreing>On
Suggestion 4.) Disable battery optimizations for all Bluetooth-related entries, Nougat is known to play nasty with Bluetooth:
Navigate to Settings>General>Battery & Power Saving>Usage>Ignore Optimizations
Suggestion 5.) Turn off IZAT low power location estimation. Contrary to it's description - this will actually actively use Wi-Fi for location services when your GPS is off. This feature is a no-go for battery life:
Navigate to Settings>General>Location>Low power location estimation>Off
Suggestion 6.) Disable Wi-Fi when screen is off, this will mitigate network drain while your phone is idle:
Navigate to Settings>Networks>Wi-Fi>(dropdown)>Advanced Wi-Fi>Keep Wi-Fi on when screen is off>No
Suggestion 7.) Disable Enhanced LTE services. You will lose HD call audio, however this feature is known to cause excessive battery usage on the AT&T network:
Navigate to Settings>Networks>More>Enhanced LTE Services>Off
Suggestion 8.) Install Greenify and Greenify pretty much everything, including system apps. Make sure you connect the phone to your PC, enable USB debugging and run the ADB commands to enable aggressive doze. It is still far better than Nougat's built-in doze.
Suggestion 9.) Pray. Jesus may not save your battery, but doing anything rather than using your phone may help the battery last longer... :angel:

Or just do a factory reset and solve a lot of the issues. I don't have the battery drain I always do a factory reset after an OTA for 2 reasons 1 it's recommended 2 it solves the optimization of apps because when changing operating systems it doesn't do a smooth transition and usually leaves behind some of the old system cache that can only be removed by factory reset

Not everyone wants to do a factory reset. It can be a big pain losing data and restoring all your apps one by one. If course this wouldn't be a problem at all if we had root, because we could use a custom recovery and clear the system cache manually.

Yup, I've pretty much figured out this phone. Carrier models (especially AT&T's) really suck because of background apps you can't disable without root (which is also likely impossible unless they'd release a .TOT/ .KDZ to be examined for root possibility). Additional installed apps drain the battery to varying degrees, especially with Nougat. Compounding everything, this phone's battery life is anywhere from 2/3 to 1/2 as efficient while using mobile data/ especially with a low mobile signal. Factory resets do nothing to fix these problems. Hopefully 7.1.2 or 8.0 will eventually be signed and distributed for us, otherwise this phone seems like a lost cause.

Strange thing it's it now works. I pretty much uninstalled everything. Then I slowly reinstalled the things I wanted slowly, over weeks. Even android wear. But there are things that still will crush the battery life. Either way it seems normal now.

I am awaiting my g6 and was curious to know the battery life , came from real life review battery standby drain on g6 to here via link. This made me lol . Thanks for the other suggestions as well , will try them out.

Thank you for this! Ever since getting this phone (Just over a year ago), the ONE THING that has bugged me is the immediate and apparent horrible battery life! I went through this and did as much as I could, and noticed an immediate improvement. Also has helped with the heat, it would get a worrying level of hot. One thing I wasn't able to figure out was this, as I couldn't find it where you indicated in settings.

You need to activate the Developer Options. To do that simply navigate to (assuming to are on G5 LG-H820, Android v.7):
Settings>General>About Phone>Software info
Now start tapping on "Build number" till you get the message "You are now a developer".
Developer Options will appear in:
Settings>General>Developer Options

Huge battery consumption, help needed

Hi all,
I am very satisfied with my device except for the battery life. I always had like 3-4 hours SOT. I was not happy but it was OK.
Lately I started charging the device every day after work (I would come home with dead phone after only 8-9 hours of it being unplugged).
So I thought the battery is defective, I must change it... and I did change it yesterday. The thing is that even the new battery behaves almost the same. It approved somewhat and now I will return home with 10% battery instead of dead phone 1 hour ago. But still the battery is terrible...
Can anyone help me, share some advice on how to improve it? I have disabled many software (even facebook), disabled location... did everything I could think of.
I am thinking some app is drawing the juice but cannot put my finger on any of them.
Some screenshots are attached that might help with your tips/advices.
Thanks!

Are you rooted? On nougat? If so get background restrictor APK here on XDA and kill background apps and tasks so they can't run if you do not open them. Lower screen brightness. Install kernel auditor and shut off cores 4 and 8.

So I thought the battery is defective, I must change it... and I did change it yesterday. The thing is that even the new battery behaves almost the same. It approved somewhat and now I will return home with 10% battery instead of dead phone 1 hour ago. But still the battery is terrible...
Can anyone help me, share some advice on how to improve it? I have disabled many software (even facebook), disabled location... did everything I could think of.
I am thinking some app is drawing the juice but cannot put my finger on any of them.
Some screenshots are attached that might help with your tips/advices.
Thanks!

uninstall chrome. Then try accubattery (better bcause after android 7, they join all in android system to mask each app consumption. If after this you still can't find out where's the problem, start the phone in "safe mode". Even the consumption is better in this mode you must do a full wipe in recovery mode (vol up+power+home) and after this, reinstall one app each time and see after reinstall the second one and so on until you find out in which app is draining the battery
If you want you can starting by disabling background data in settings but I think isn't the clearer way to find out

This is going to surprise you.
I've had this phone for years and I've tried everything - and the BEST result is when you DON'T DO ANYTHING except disable Facebook and Instagram, and any Google Apps you don't use.
Do not tamper with anything else.
I figure that Samsung tunes this phone so tightly that if you leave it alone it operates as it should.
Anytime I disabled anything else, battery life suddenly and drastically reduced.
The phones runtime software kicks in and if you have disabled something it checks routinely, it will keep the phone awake constantly looking for a ping back from that process.
I just went through the whole process again meticulously, App by App.
Also DO NOT enhanced messaging OR the device antivirus. If you have, you must reset and then train yourself not to engage these too regardless of how hard The phone tries to persuade you!
Then - the battery life becomes like a normal phone which means you'll still need to charge everyday but it will take you through a full heavy day... And this is fantastic!
Honestly try it and you'll see what I mean. The S6 edge plus is so finely tuned, anything you block will start a feedback loop.

I had similiar problems , the way i fixed it, i disabled/uninstalled all samsung applications what i dont use, i disabled/uninstalled all google applications what i dont use. Cold weather (like -20C) will affect the battery life too.
Disable / uninstall apps you dont need. That helped me a lot and got even more battery life while at stock nougat rom with all updates installed.
try wiping cache from recovery and reboot your phone.
I hope this helps you
