Before I begin, let me state that I have already factory reset countless times and reflashed my firmware at least 3 times in the past week. Neither of these have helped me at all, so PLEASE do not suggest this. I've been trying to solve this problem for a week or two and everyone has suggested this to me and of course I've already done it, so it hasn't helped me at all.
PHONE: E980
FIRMWARE: Stock 4.4.2 E98020g
BASEBAND: APQ8064/MDM9x15M
SYMPTOMS:
-Battery draining ridiculously fast (appx 10%/hr, but before my last reflash, it was draining 50%/2hrs!)
-Phone only lasts about 5hours.
-Android OS is consuming about 80-90% of battery, followed by Screen at around 10%
-Phone is constantly warm
-Phone rarely enters Deep Sleep (it stays awake 95% of the time).
TESTS DONE:
-As I said, I factory reset numerous times with the same exact problem
-I reflashed my firmware 3x, with same problems
-I usually keep auto-sync on, but the issue occurs whether it is on or not.
-There is supposably a Kitkat 4.4.2 (in general) issue where the camera will consume a ton of CPU resources and get stuck that way. I haven't used my camera much, but do use Smart Stay, so I disabled this. No positive result.
-Disabled the Google Now "OK Google" hotword detection. This helped reduce the drain, but didn't solve it. Drain went from like 15%/hr to 10%/hr.
-Took battery out of phone for 10 minutes and placed back in. Seemed to help at first, but after about an hour or so, it returned.
-"Recalibrated" the battery numerous times. This was done by draining the battery until the phone shut itself off. Then I charged the phone to 100% while the phone was still off. Once the phone read as having 100% charge, I let it charge for another 1 hour. Then I unplugged the phone and booted it up. Again, this appeared to help at first, but after a while, the phone began to drain rapidly again.
NARROWING THE ROOT PROBLEM:
-Both WakeLock Detector and BetterBatteryStats show "wlan_wake" and "wlan_wd_wake" as being the largest wakelocks.
-As previously mentioned, "Android OS" is consuming a huge amount of battery
-Problem only seems to happen when wifi is on, whether it is connected to an SSID or not.
OTHER:
I have narrowed the issue down to wifi but I can't seem to figure it out any more than this.
Both of the "wlan_" wakelocks are caused by wifi being on and I need wifi on whenever possible because I can't afford a huge data plan. My current one is 2GB/mo and it is shared between 3 people.
I noticed today that my phone drained 10% within 1 hour after taking the phone off the charger, and I was connected to my home wifi. I then went to work, but still had wifi turned on on my phone. At work, I was only connected to mobile data (but the phone was just sitting in my pocket). The battery drained another 15% within an 1hr 30min, and the phone was warm in my pocket (very uncomfortable!). I then turned wifi off completely, and the battery drain completely disappeared!!! The battery life was amazing in fact!
PICTURES:
I've provided some screenshots with notes. Please take a look at them.
I'm going to manually make the problem happen again and will upload new pictures afterwards. They will be of WLD and BBS. Any current info I have is tainted since I turned wifi off and the problem temporarily turned off too. I want to get only screenshots of what is going on when the problem is happening.
EDIT: BTW, the problem occurs whether my mods are installed or not (the mods used to remove the icons in statusbar, AdAway, etc)..
The issue seems to be pureply related to wifi and nothing else.
IDEAS:
Could adding a wifi supplement scan interval to the build.prop solve this problem?
Is Wifi bugged in this firmware? (This never happened on Jelly Bean!!!!)
Is maybe the "Battery Saving for Wifi" feature bugged?
Would maybe flashing the Jelly bean modem (e98010p) solve this issue (since it didn't happen on Jelly Bean)? If so, does anyone have a flashable version of this? <- I just did some research and it seems that the baseband (AKA modem) is the same in Kitkat as it was in Jelly Bean. Weird....
These pictures were taken shortly after making my first post. I already had wifi turned off, so I turned it back on and after a few minutes, the battery began to plummet. I went from roughly 77% to 66% in just an hour!!!!
Just to make sure that it is clear, I have both BBS and WLD set to start recording data after the phone has been unplugged from the charger. So to restart the data collection, I simply plugged the phone into my charger for a few seconds and then removed it. THEN I turned wifi on. The data seen in the pictures should only have occurred between the time when I unplugged the phone and the time I took the pictures.
EDIT: Also just to make sure it's clear: All the data shown in the System picture is actually since I unplugged the phone this morning. I only posted these pictures to show any changes from the similar ones posted earlier.
PLEASE! Can anyone help me solve this!?
Or is this a major Kitkat bug!? (or ATT bug, or modem bug, etc etc).
After a full week of this problem, I think I just made another breakthrough. Unfortunately, I think it IS one of my Xposed modules, which is weird because I didn't think any of them would have a need to constantly connect to the internet.
All I know is that I just completely uninstalled the Xposed Framework and the phone started to sleep like a baby... with wifi on!
Now I just need to pinpoint the module, which I can do myself.
MODS CAN CLOSE THIS THREAD.
Sorry I created it and (mostly) solved my own problem. This happens to me a lot. I have a problem, can't figure it out, ask for help, then solve it myself. :/

In this case, I need to be more specific about my solution then.
The problem seems to be caused by the module, Xposed Torch. It's still usable, but you need to tap the overflow (3-dot) icon and disable ads (it's free to do this). The module requires internet access permissions, which I was not aware of, and it constantly connects to the internet to stream the ads. This in turn causes the wifi to constantly receive data (thus the wlan_wd_wake and wlan_wake). When wifi is on, but not connected to a network, I think it forces wifi to constantly scan in order to find a connection so that it can get that ad data. I'm not sure why it doesn't just use mobile data though... unless it does and it's just more power efficient.
So far, I have disabled the ads via module settings and the phone is now sleeping like it should.
So if anyone else is having wlan_wake wakelocks of any kind, especially followed by wlan_wd_wake or wlan_rx_wake, then this means that something on your phone is constantly accessing the internet via wifi. FIrst turn off auto-sync, and if this doesn't help, then you need to uninstall apps until the problem ceases.
My phone is currently icy cold in my hand and I've never been so happy to feel it like this!
Problem came back today. I've basically uninstalled every app now and the battery is still draining whenever wifi is turned on.
Under Better Battery Stats, there is a process (?) called dhc_dpc that's been running the entire time my phone has had wifi on. There are also the wlan_wakes too. (NOTE: IIm backing up my phone right now, so these names are coming from memory).
According to this thread (different phone and unknown Android version, but similar problem), the wifi driver may be bugged. They recommend doing a reinstall, but I've done this many times now and it doesn't seem to help:
http://forum.xda-developers.com/galaxy-s2/help/dhddpc-t1246190
EDIT: I think I've found the culprit and while it is definitely wifi-related, it's NOT an app. It's the actual Android system constantly pinging the internet. According to my research, it's constantly collecting location data by using either mobile data or wifi and will do this whether you have location services (gps) or Location Reporting enabled. This has been described as a "bug." It was introduced by Google as a cool new feature, but it's implementation was buggy.
I am currently testing a fix to resolve this issue, but want to be certain that it's fully working first.
Just an an FYI, this fix SHOULD help anyone running Android 4.4.2 and experiencing high battery drain caused by Android OS. Even better, the fix does not require root, so anyone can do it!
have you try a full factory reset using lg driver to bring full stock rom back and not just a factory wipe from the phone

Not to be rude, but the first sentence of my first post says I did this several times.
I had those ridiculous battery drains on both stock ROMs with xposed, but never found a direct connection with it.. So first, (if you already haven't), try to disable xposed completely and try again. LG's stock ROM doesn't like that kind of modifications. Also, one of the biggest problems I had with Kit Kat was Location services, so you should check them too.
If that doesn't help, check your apps and download stats, maybe there is something downloading or trying to download stuff.

It's definitely Xposed related I think.
I've disabled Xposed during some testing a day or two ago and yeah, battery definitely improved.
The only modules I have installed are:
App Settings
Enable BatteryStats Permission (just to allow me to track this issue. I installed this after problems had already begun)
Greenify (all Xposed settings checked)
YouTube AdAway
I have also been using G2 TweaksBox up until last night. I only used it to declutter my status bar and to enable the advanced reboot menu. (I hate all the icons in the status bar!!!). Last night I disabled G2 TB and battery life improved dramatically!
I can't explain why G2 TB would cause battery drain, but I did notice it doing something odd yesterday. I have the lockscreen off sound enabled in the system settings, so I hear the sound whenever I lock the screen. Well, I turned my phone on yesterday for some reason when in my car. I then turned the screen off, heard the lock sound, and started driving. 15 minutes (NOT seconds!) into my drive, I randomly heard my phone make the locking sound, but the screen was not turned on!! I wonder if G2 TB delays my lock somehow.
I switched to GravityBox[KK] today since so many people claim that it works perfectly on their OGP, and so far, battery drain is MUUUUUCH better than with G2 TB activated, but it still may not be as good as pure stock. I need more time to figure it out though. This morning, my battery dropped 5% in 40 minutes while connected to my home wifi. I then left my house for a few hours, but left wifi turned on on my phone (it's hard for me to remember to switch it off and on all the time!). The battery seemed to be pretty stable after that, but I can't explain the weird 5% drop, but I did receive 2 missed calls and a text during that time too. Should I lose 5% just from getting a text and having my phone ring?
It's now night time and I'm at 75% battery. This past week, I would be at about 10% by now or even DEAD, so I'm happy as heck right now.
I would LOVE to be able to keep using GB, but I now just need to figure out if it too is draining battery, or if everything is stable. I'm going to continue comparing stock VS GB tonight and tomorrow. I'll live with stock if needed, but I'm just very OCD about the statusbar clutter.
In GB, I only disabled some icons, centered the clock, enabled advanced reboot menu, and enabled the lockscreen torch.
Try with GB and post results, it looks like it doesn't drain that much... Unfortunately for me, I had problems with every xposed module ever tried, so I simply gave up and now I'm using another rom. I think that LG's ROM is problematic, especially if you use a lot of SystemUI customisations, like GravityBox does.
Are wakelocks from orginal post still active?
G2 Tweaks aren't even compatible with our phone (as much I understood), never managed to do anything with them. I assume that G2's SystemUI is too different from OGP's, so that may be one of the problem sources.
With my normal usage (1-2 hours of music, 2-3 hours of internet - wifi or mobile, K9 sync, viber, sometimes games, ~60 SMS and few longer calls per day), battery was holding up to 35, sometimes 45 hours. With xposed, barely a day, if I turn mobile data and sync off. I usually have a dilemma about putting it to a charger before sleep, there is alway around 60-50% of battery at the end of the day.

OK, so I just got home from work and today I not only had GravityBox disabled, but I also had the ENTIRE Xposed Framework uninstalled.
My battery is now at 30% and I was only gone for 7 hours!!!!!!!!!!!!!!!!!! This is ridiculous!!!!!!!!!
*sigh* <- frustrated with this whole situation
Yes, the wakelocks are still active.
The top two Kernel Wakelocks are "wlan_wd_wake" (46.3%) and "wlan_wake" (46.2%) in that order. The next in line is "PowerManagerService.Wakelocks" (8.0%) and then "msm_hsic_host" (6.1%). This was since my last reboot, which was about 2 hours ago (I had to rebooted after removing an app that I thought was the culprit... apparently it wasn't).
Again, I keep Auto Sync on, but disablign it seems to not help in this matter at all.
I also keep wifi on. When at work, it isn't connected to a network, but I often forget to disable wifi when I leave the house, or I come home and forget to enable it and end up sucking my data plan dry. Nonetheless, I also did this while on Jelly Bean and had no issues whatsoever.
My phone is only staying in deep sleep less than 10% of the time and the time when it is awake, the CPU is running at full 1.7GHz! This is causing the phone to get warm in my pocket. It doesn't hurt, but it's enough to make things uncomfortable.
According to the battery stats (in system settings), Android OS is consuming 83% of the battery.
The biggest network drainers are "Google Play Services" (33.3%), something simply called "0" (14.8%), and a weather app. I had the weather app open manually not too long ago though, so that explains that one, but the other two I can't. I have no clue what "0" is and I have not opened Play at all today.
It's something to do with wifi itself I think, and maybe not a specific app accessing wifi. (?)
I turned wifi completely off about an hour ago and the battery drain has been stable. It's been like this for days too. If I turn off wifi, the drain is "normal." If wifi is on and connected, drain is higher than with wifi off, but barely. If wifi is on and not connected, the battery level plummets like a rock in a pond.
OH! One thing I just thought about and should mention:
Before I discovered that G2 TweaksBox was causing serious drain, I was on another battery-related thread in the OGP forum. Someone told me to delete the "libiq_client.so" file from System/lib. He assured me this would give me excellent battery life (which apparently it did not). So I did. Normally, I just rename system files so I can restore them if needed, but I guess I accidentally deleted this one.
Could this be causing the drain, and if so, can someone upload a copy of libiq_client.so so I can try it on my phone (after setting it's permissions correctly)?
Um, that's not good.
Check wireless settings, and disable "Scanning always available" if enabled.
You don't have a nand backup, do you? I have E988 variant so maybe my file isn't good, I don't know if there are big differences between them. I can upload it if you want.
It is possible that Google Services are messing things up since they are between top processes... have you tried clearing their cache/data? Also, if you have a custom recovery, clear cache/dalvik cache, maybe it helps. Also, if High precision location is enabled, try disabling it if you don't need that service, I had some problems with that in combination with weather widgets.
What partial wakelocks are active?

"Scanning always available" has been disabled since day 1
The only nand backup I have is after I already deleted the file :/
I did try clearing Google Service's cahce/data at one point and I think it helped for a few hours. It may have been a placebo effect though. I also di the recovery cache wipe and dalvik wipe with same results.
I don't keep location on at all since I don't use it. It's always off, but at one point, I did enable it to select the battery mode and then turned it off again. I did this mainly so that if and when I do use location, it would always use Battery and not High Precision.
I'm currently backing up my rom, so all partial wakelocks were cleared for now. Sorry.
I'm trying to reflash the stock rom real quick and grab the libiq_client.so file, then restore the backup and insert the file back into system. Unfortunately, I may not be able to tell if it solves the problem until sometime tomorrow.
EDIT: BTW, the only reason why I won't just start all over again on the reflash is because 1) I want to figure out what's causing this problem so it won't happen again, and 2) I don't have the time to spend hours setting my phone up again
EDIT2: Oh and every time I reflashed my ROM, the first things I did was rename/delete that library file and installed G2 Tweaksbox. And every time I had horible battery drain, so i'm really hoping it's due to the lack of this library file.

Try it. I can upload file from my backup if you're willing to experiment with that, to save you from all that flashing.
Also, if you edited your build.prop and changed pm.sleep_mode and ro.ril.disable.power.collapse, undo that. It only disabled deep sleep state for me (had similar problems few days ago when flashed a new rom, mmc1_detect, suspend_backoff and some other weird things, so I even tried that)
Have you tried using another roms?

It's OK, I'll get the file from the flashing. I know it'll be a pain, but this may be safer just in case there is some sort of difference between the E988 and E980 versions. I doubt there would be, but better safe than sorry I guess.
I did add those settings to my build.prop as a test, but I was smart there and backed up my stock build.prop first and ended up restoring it a few hours later. It was causing my screen to not always turn on when I pressed the power button.
I have not tried any other ROMs. I prefer to stick to stock ROMs (or modified versions of stock... basically anything stock-based and not CyanogenMod or AOSP). I had bad experiences with AOSP-based ROMs on my old phone.
If I tried a stock-based ROM though, it must have everything working though. I mean everything: calls, texts, LTE, bluetooth, speaker phone, etc etc.
EDIT: OH MY GOSH!!!!!!
I just found where the libiq_client file went. I moved it to my internal storage.
Well, good to know I wasn't totally stupid and knew not to completely delete the file! Unfortunately I was still dumb enough to misplace it....

Libiq.so enables carrier IQ, its removal should only help battery drain, not cause it.
Just to ask, have you tried adjuating wifi scan interval? You can try as well the xposed module, "wifi deep sleep". Helped minimize my wifi related drain
About 3 days ago the battery drain on my Nexus 5X went crazy. I found out that the "app" Android System do not let the phone sleep and keeps it awake all the time. That is why the phone can not even get into doze mode and drains about 8% per hour when the screen is off. I tried restarting the device and also force stopping the Android System. Both without any succes. Do anybody knows what to do with it? Or should I just wait if it will go back to normal? I do have screenshots, but the XDA will not let me post outside links...
Interested about that.

I am having the same problem. It occurs randomly, most often when I have just charged the phone and removed the cable. If i am correct, a wakelock under the name *backup* is holding the phone awake, it might be the same in ur case. I've done a research on this, turned out this is unfixable unless you have some sort of wakeblocker, which my current rom lacks of. I tried using xposed with its modules, but it gave me a ton of bootloops and i gave up on it. The only temporary fix for me is to reboot the phone. Until it happens again. No clean flash nor anything i have tried seemed to have helped. I even tried disabling all services and receivers from Android System, no luck again. That is one hefty problem

I have exactly same problem with wakelock. It happens only after charging. Everything is OK after restart.
It has happened to me sometimes on my old HTC One X and I think it happened also once on this 5X, but it was just for about a day or so. It disappeared itself with time, I didn't do anything with it then. Now it's been 6 days, I have to charge the phone twice as frequently and neither the reboot nor the force stopping everything works. I really don't know what to do in this case. Also this phone isn't rooted yet, so I can't just flash the system again as on my old HTC... I'm still hoping it will disappear by itself asap
But do you anybody have any other ideas what can I try to do to stop that crazy system app?
same problem here...
had the phone about 350 hours with no restart and i thought i would give it a reboot..
same think happened...android system was going from 2% to 20% in a matter of hours..
installed an app called GSam Battery monitor..showed me the phone was not going in deep sleep (Doze mode) at all...
here is an attachment if anyone can understand better than me..
I posted a similar thing in the battery life thread. Very odd really as I've had the phone a few months now but it also only started with me a few weeks ago. Really can't think of a trigger for it... I doubt the April update would have been significant enough to create an issue, but who knows.
Exactly. After about 4 months of working excellently and about 400 hours without restarting, after charging it's immediately goes into this "mode" when the Android System won't let the phone sleep. Even restart didn't help me, but now after 3 restarts it goes to normal. One bad thing... after every single one charging, every time I put the phone on the charger it goes crazy again and I have to restart the phone after every cutting of of the charger... it makes me really angry when the phone is only 4 months old and even the "okay" battery life isn't that good on this phone... God I just need to find a solution, that's insane...

THIS!!!!
the phones battery life was a big "ok i can just play a bit less so i can get through the day and IF anything happens i know it has fast charge so ok"
nowadays i have to reboot after EVERY charge....
p.s.
anyone that faces the same problem but WITH mai's security update? do we have any hope that it will fix that problem?
Not sure if it's a one-off, but I decided to uninstall the game "8 Ball Pool" by miniclip as it appeared on my battery usage stats when I'd not opened it in days. Since then, even after a recharge, the phone seems to be going to sleep as normal.
I'll monitor to see how things go but perhaps it could genuinely be a rogue app. It's a little disappointing that doze wouldn't block the keep awake requests - I thought that was one of the main purposes of it.
The same issue occurs for my Nexus 5X: after device disconnected from a charger, Android System process starts to keep device awake until next restart. As I understand from comments above factory reset does not help to solve a problem. Has anybody met the similar problem with custom ROMs/kernels?

It started with the latest update I think. It hasn't happened once ever before. I hope they already know what's happening and with the May update it will be gone. I don't think there's any other solution when you don't want to flash custom ROM and stay on stock... :/ we have to wait.. :/

Hmmm, sorry for offtopic clarification... as of now I'm little bit confused about Android versioning, especially it's unclear for me: whether you mean as latest update: 6.0.1 or april security patch or model build number (like MHC19Q, which is currently on my device)?
I guess it must be April security patch. Some kind of problem in the Android System app that comes with the security patch. I don't really know in this case, but as I've said, it hasn't happened once before the April patch

I rolled back to MHC 19J. The April MTC19T Build cut my battery life in half. Android system being the top culprit. Deep sleep never going over 80%. Horrible idle drain. Would drain 15% over night while i slept. Exact same setup as before, no new apps. SOT went from about 5 hours to not even 3.

MTC19T is May update. I've updated my device to it yesterday and the issue hasn't been fixed yet: a device is still kept awake by Android System after disconnecting from a charger. @ScumDroid, could you please confirm there is no such issue on MTC19J after rolling back?
Jandiey said:
Exactly. After about 4 months of working excellently and about 400 hours without restarting, after charging it's immediately goes into this "mode" when the Android System won't let the phone sleep. Even restart didn't help me, but now after 3 restarts it goes to normal. One bad thing... after every single one charging, every time I put the phone on the charger it goes crazy again and I have to restart the phone after every cutting of of the charger... it makes me really angry when the phone is only 4 months old and even the "okay" battery life isn't that good on this phone... God I just need to find a solution, that's insane...

Same issue. After running it for few months flawlessly, the Android System is keeping the device awake and only restarting it solving the problem temporarily. Charging the phone again starts the wake lock..
Most disappointing is it's the 'Android System' that causing the problem. If any app/game is linked to this, it should have been appeared as the culprit but unfortunately it's that 'System'.
Waiting for solution.
Samsung users are having the same problem.
I have found something on my Samsung Galaxy S6 in regards to 'Android OS' killing the battery. It might be the same for Nexus users, I've confirmed this on a Moto G 2015 running the latest MM update and on a Samsung Galaxy S6 Edge. By latest update, I mean the April security patch.
Check this and this.

Sorry for the late response mate. I have no issues with android system draining battery in MTC19J.
Guys,
i need some help. Over the last two days, my battery has just gone. The attached screenshots are from earlier this morning. I'm really not sure what's causing this. I lost 11% in under an hour and my phone was telling me it has 4 hours of battery left. I haven't installed anything new in the last two days.
I've tried using better battery stats in the past. I'm not sure how these apps work. I noticed my cell service isn't that good but I'm at home, always on WiFi. Can someone point me in the right direction? This phone is not even two months old.
Thanks in advance.
I highly advise you to turn aeroplane mode on and enable WiFi calling if you have it. It saves so much battery! This is whilst your indoors of course. Keep your brightness below 40, disables location when you don't need, disable auto update and sync behavours, disable NFC and Bluetooth if not being used. Disable animations via developer menu.
Your screenshots don't seem to show how much battery Android OS is using and there's nothing battery draining in what you did include, so I don't know that anyone can really do a lot to help you beyond offering very general suggestions.
What Rom or version of Android are you running? If you are running stock did a monthly OTA update install recently? It is that time of the month.
It's possible you have a rogue app but there's nothing showing up in your screenshots. It's possible that Google, Facebook or some other app is getting sync errors. Where you would check for that would depend on what OS you are running.
You could contact Pixel Support but my guess is that they would have you try a factory reset, which might be your best course of action based on the limited information you have provided.
My battery percentage currently shows 61% 1 day and 7 hours left, so you definitely have something wrong.
I would personally start with a factory reset. You could also run the phone in safe mode for a while and see if the problem persists. If it doesn't then the issue is likely a third party app.
When I had my battery issues, I factory reset and just ran stock for a couple days. It turned out I had to RMA it due to a bad battery. Phone was dying between 20-60%. I would barely get 1 hr SOT

Your screen was on for the majority of that time. And that 4 hours left means at the current rate you're going you'll only get another 4 hours. That is nothing more than an estimate and it will change all throughout the day based on you're use. Try letting you're battery drain all the way to zero 3 times. This should calibrate the battery. Try monitoring it after that.
And a side note. Use you're web browser for Facebook. The Facebook app has been a known battery destroyer forever.

I:m running Pure Nexus ROM with the Elemental kernel.
Thanks for all the responses everyone. I will try to drain my battery and see if that helps.
I had this problem. I went in and disabled all of my Google apps. I then went back and re updated them in the Play store After that I did a restart and I haven't had one since. I also recommend not having a battery case as both the Mophie and ZeroLemon both caused huge wakelocks for me. Cheers. ?
Hello.
I've bought a G4 in March and only 20 days ago I've started to notice a odd and big battery drain. Android tells me it's "Android SO" consumption. What once drained like up to 5%, now drains more than screen. 20 days ago, battery lasted like 34h. With same usage now, turned 12h.
I've uninstalled the apps I've installed meanwhile, used it in battery eco mode and even on airplane mode, without any luck.
4-5 days ago I've installed Wake Lock Detector (no root, but with the right permissions) and Better Battery Stats. From what I understand from the reports, they don't blame any specific app but show thousands of wakelocks on Android SO. I believe sometimes it can be normal (for instance, when I run with GPS and music). Anyway, maybe the issue lies here.
What I find really odd is that those 2 apps say that the phone is awake more than 90% of the time. Like 1h of deep sleep only per full battery.
I could understand if someone says that it's the battery that had a great use already, but not only has 7 months of use, but also the phone behaviour changed (Android SO was never so high before, at least constantly).
Thanks in advance for any advice!

Suggest you check out and install the apps recommended apps on ✭[GUIDE][26-07-2016]Extreme Battery Life Thread(Greenify+Amplify+Power Nap)✭ at https://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
Read the OP thoroughly for each app discussed. The wakelock situation can be helped a good deal with Amplify and Greenify in particular - the paid versions - but I would also install AppOppsXposed - all require Xposed which requires root in order to be installed and I would also check out Power Nap to see if any incremental improvement.
You may a also want to run a malware scan ...
Thanks for the info. I checked it earlier, but most of those apps only run in root phones. I'm waiting for official Nougat in G4, mostly because haven't saw yet a Nougat image for this device without any problems, like camera not working, or such. I wouldn't mind to pay for apps that could work on this, but I want to avoid rooting. I guess I rather put Android 7, that has a bigger chance to even solve this problem, than root at this time.
Haven't said earlier but did a factory reset yesterday and device kept the behavior... I believe a hard reset would reduce almost to 0 the eventual malware problem.
No obvious alternatives for not rooted phones? Haven't this happened to someone else and been solved?
Thanks!
I had the same problem a few weeks ago...i was loosing ~30% of the battery at night with no wifi/data/gps etc. I tried everything...factory resets, different roms, greenfy & those kind of apps but the phone would not sleep. The last thing i tried was a factory reset and after i logged into my gmail account i set the phone as a new device...so no restoring apps and backups from my gmail account. Now everything is ok, my phone sleeps like a baby. I've read somewhere that it might be related with the syncing & backups....i don't really know, but you can give it a try.

Haven't tried that yet. I'll try to remove and add the device again, to avoid the pain of a new hard reset.
To have a reference, it was good to know an average percentage of other G4 deep sleep. If everyone has around 90%... maybe it's not a problem at all. The "sleep like a baby" is which percentage? Also, there are plenty babies that wake up hourly crying for a period of time...
Thanks for the tip!

My phone was awake >90% of the time(when screen was off), even in flight mode, when it had "the problem". Now things are back to normal...~2% awake when the screen is off.
Hello again.
Tried to reset a couple more times, tried to remove old phone register in my gmail account, but I wasnt successful.
How you did the
"The last thing i tried was a factory reset and after i logged into my gmail account i set the phone as a new device..."
?
Once it asks for my account, I'm not able to set it's a new device. I also did no restores... Is there a way to disconnect devices from Google account? I was only able to do so in devices I connected like one month, or more, ago, but not able to do so in the device I'm using at the moment.
One thing I did not try but that would confirm your thesis is to register device with a new account.
Anyone with an alternative?
I'm hoping LG really releases Nougat for G4 in 2017...
Today, the device returned to normality without any intervention. I can only imagine the following: since last factory reset I've disabled some apps I didn't used, like Google books, or Google music, but only yesterday I did a normal reboot (due to huge battery drain...). Eventually, some updates just took place after this reset. Anyway, even having imagined this theory, I don't believe in it. Wizardry, I bet.
