Odd Problem with SGHi257M

The problem is that the phone will not ring for either incoming or outgoing calls. Someone phoning me gets no rings, it goes immediately to voice mail. When i try to call out the screen looks perfectly normal - all of the correct icons are showing up so it looks like it is ringing, but it is not ringing either at my phone or at the person i am calling.
The problem is cured by restarting the phone. Only after i restart the phone do i get notification about any messages that were left.
This happens only when the battery is at about 40%, but not always - just occasionally and rarely. It happened today for the first time in a few months; it also happened a few times, a few months ago.
I would think that at 40% battery there should be no battery charge related problems? 40% should be plenty to run the phone?
Any ideas? I am going to return it to the store and ask about this, but i would like to have some more info to go on, if any is available.
TIA,
Mick

Update: It may very well be happening more often than i thought. I do not get a lot of calls, certainly not every day, so it could be quite consistent and i may not have noticed. For the next while i'll let it run down every other day and check.
It happened today. I just decided arbitrarily to check. Battery at ~35%. I phoned to check if i had any messages. Everything looked normal as i said in my original post, but it did not ring and did not connect.
Before re-starting i checked to see if Mobile Data was working. It was not. After re-start both Mobile Data and the Phone were working.
I am wondering what is the technical significance to the Phone problem of the Mobile Data also not working? They must be somehow related in the hardware or software structure of the phone.

I got my phone back today. On the report it says ...
Complaint
#1[]C56-no service
phone antenna cutting out intermittently
Symptom code C56
Work performed
[202]-Full sw upgrade & phone reset
;sw re-flashed then rebuild to factory default
Repair code 202
I'll see if it happens again or not over the next few days and report back. To me it sounds like they did nothing to the physical components of the phone, just flashed/installed/configured the various software components.

Here we are, exactly one week later, and the phone failed in exactly the same way. So the "repair" process they applied did not work. I'll be returning it to the Rogers store today and will report back here with the results.

I may have the solution to this problem of network drops now, finally. I took it back to the Rogers store where i bought it. This time there was a more knowledgeable guy there. He took one look at the screen and said "I know exactly what is the problem". What he noticed was that the LTE notification was not showing. This city is an LTE hot spot. The phone should connect with LTE virtually anywhere, anytime. He said it is not the phone at all, but that there is a "switch" that needs to be reset for my account; something to do with the SIM card. After a couple of phone calls he returned the phone and said that it is fixed.
Time will tell. I'll post again.
Mick

False alarm. The fix made it worse. Now it not only drops network connections, but also drains 50% of the battery over the course of one day with very little use. Used to drain 20%.
Mick

Just reporting that the so-called knowledgeable guy was incorrect. Still dropping the networks. I went back and he was incorrect again as he believed that you had to have Mobile Data enabled to make/receive calls. Oh well, he was doing his best. Got thru today so far with no dropouts, and battery drain returned to normal ~20% loss for the day. Will see what happens overnight and tomorrow.
Getting kind of tired of having an unreliable device. Hope this gets settled soon. I'll be back to him as soon as it drops out again.
Mick

I really do wish some of the more technical guys on this forum would take an interest in this perplexing problem.
Here is a summary of this problem and of the work done by the official repair center, the results, and finally at the end a couple of questions ...
Here is a description of the technical problem with the phone ...
1. The phone will work normally for an indeterminate time period, perhaps a few hours or maybe a week or so. Then it will malfunction as follows -
2. Signal strength is tiny. The phone will not ring for either incoming or outgoing calls. Someone phoning me gets no rings, it goes immediately to voice mail. When i try to call out the screen looks perfectly normal - it visually appears to be calling as the active icon is on the screen and the message says "dialing". There is no dialing sound. It never connects, it eventually gives up.
3. Mobile Data is not working. With Mobile Data enabled there is no icon on the notification bar. Google search and PlayStore do not run.
4. Wi-Fi is working. The icon is on the notification bar when it is enabled. Google Search and PlayStore work with Wi-Fi.
5. The problem is temporarily cured by restarting the phone. Only after i restart the phone do i get notification about any messages that were left. Then eventually the problem re-occurs.
When i sent phone back the first time this is what they did ...
[202]-Full sw upgrade & phone reset
;sw re-flashed then rebuild to factory default
When i sent it back the second time this is what they did ...
[051]-No trouble found
;RF Calibration performed to enhance RX/TX performance and network connectivity. Passed RF compliance test to meet manufacturer soecifications. Adjusted battery level to optimize power usage
When i sent it back the third time they did exactly the same as the second time. The phone is now working better as i will explain, but it has not been long enough to confirm if the real problem is solved.
I have set up the CleanMaster [CM] and BatteryDoctor [BD] Apps. I have turned off any automatic options in both. I make only light use of the phone - a few calls per day, maybe one Google search, nothing else. I run the 1 Tap Boost CM Widget and the Save Power BD Widget after each use of the phone.
I also have installed NoWallpaper [saves a wee bit of battery power], SmoothCalendar [very nice and very useful] and one of the Clock Apps [with a useful 1 x 2 Widget].
I have not yet disabled the 50+ Apps that CleanMaster reports as harmless to disable as my phone is still under warranty and has this issue that the service people have not yet been able to resolve. But i will be doing that and i highly recommend it to others.
I have had the phone back from the 3rd repair for 6 days now. I am leaving it powered on overnight. At the end of the first day battery = 89%, second day 74%, 3rd day 55%, 4th day 46%, 5th day 31%. That is 5 days of light use. Was 23% this morning so i re-charged it to 100%. I'm happy with 5 days of light use.
I do not have written notes on the previous battery performance. But from memory it used more than 20% the first day, at least an additional 30% the second day. There was not enough to trust it for the third day as it lost more overnight. I was running BD and CM, using the CM Widget but not the BD Widget.
I am wondering when the phone will fail again. I'll post again when that happens as i feel certain that it will. But i secretly hope it will not
So, finally, here are my two questions ...
What is the actual, presumably hardware, problem with the phone that they are not able to find?
What did they do to improve the battery performance so dramatically? Did they for example lower the CPU clock rate?

I have posted about this problem on four S4 mini forums and on one S forum. No one has ever seen or heard of this problem. It is clear that my phone is the only one with this problem.

Thanks fort the response, i told her not to get the phone.

Well, it gets worse. The phone messed up today same as before. A bit more than two weeks after the "repair". I was at home in one of the strongest signal areas. Would not receive or make calls or use mobile data. So back to the Rogers store. By the time i got there it had started working again so i could not demonstrate the problem. Also used a lot of battery power today, about 40% with light usage compared to 15% or less per day for the past two weeks.
What the counter guy at the Rogers store said is that there is nothing wrong with the phone, that all cell phones do this, and that i should adjust my expectations.
Here's another ConnectionChecker app. This one attempts to reconnect ...

PLEASE help me troubleshoot my ridiculous battery drain!

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?

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

[Q] Reboot problem when not charging

I have had my P607T for a couple of months now. It is box stock no changes. Over the last few weeks I have noticed that it will reboot while using various apps. (Fliipboard, Chrome, Clash of Clans, Papyrus...) They don't seem to all be heavy graphics or network. The only symptom is that the screen starts to flash then "bang" reboot (and trouble rebooting when not plugged in). It would not be too annoying except that it will loose wifi settings and the wallpaper. I have tried different wallpapers (saw a thread blaming the live wallpapers ) Unloaded some apps (had another phone issue with FitBit and HTC blink on my N4). I stay away from CoC (my base has been raided so often now ...). Any thoughts? I am really trying to like this tablet more than my old ASUS Transformer but this reboot and reset wifi is a pain.
Thanks in Advance,
marka

Have you tried a factory reset? I'd make tmobile replace it

was hoping to avoid the reset button. Tried it and still giving trouble it rebooted while restoring apps. I bought the tablet on ebay, I don't think TMO will take it back. oh well I'll keep poking about.
thanks,

I experience exactly the same problem since the update to 4.4.2 (kitkat): The screen starts to flash, suddenly the tablet reboots. I tried a factory reset multiple times, also removed the SD card and reflashed the ROM via KIES, nothing helped so far. Also, even when plugged into the outlet for several hours the tablet didn't charge at all (I think it stopped charging when the screen saver kicks in).
A couple of weeks ago I filed a RMA request (my dealer sent the tablet to Samsung), yesterday I got it back. It was charged at 60% and when I plugged it to the outlet it actually charged (even when the screen went off). But after about one hour (the battery was still > 60%) the flashing reappeared and after a while the tablet started to reboot again. Interestingly the battery now showed only 2% and the low battery warning appeared.
I think the problem might occur only when the battery runs low (which happens very fast as something seems to drain the battery), while android still shows a much higher battery level . Never experienced these problems when the tablet was plugged in so far.

At least I don't feel so alone with this issue... I have been paying more attention to my build up process since the factory reset. I found, the other night quite by accident, that when I logged in to Twitter the reboot started. So for the next few days I have left Twitter off the machine and it is doing better. I suspect that something is hitting the power drain (like you mention) and that causes it to have problems. In that thought I have also turned off the power saving mode and auto screen now just to add to the list of things I am avoiding.
Rgds,

Have you considered rooting and using root apps to stop the apps from being able to do such things?

Battery drain

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.

Notifications Issues

I know this will be almost impossible to solve with suggestions, but some of my notifications don't come through until I unlock my phone. Most notably WhatsApp. I've turned off all battery optimisation options, removed it from the sleeping apps list, allowed background data and turned off data saver. Still have the same issue.
I have naptime installed so turned that off as well.
What's strange is that a few days ago all my notifications started coming through as normal for a few hours, and then stopped again.
I know the only way to solve this is probably a factory reset, but with loads of tweaks I've gotten it so my battery life is amazing. Leaving it overnight it drains around 3% and depending on how I use it I get around 8h of SOT with 50% battery left so I don't really want to factory reset.

What launcher are you using?

I feel your pain with factory resets.
There needs to be a backup settings to cloud so you can easily restore them after a reset or even a change of phone.

I understand your frustration with this issue, I experimented it as well when I started using my device, back then I did not fully knew about all the battery optimization settings, but, when trying to get all the notifications right, I stumbled upon an app named PNF-no root, which is meant to fix the push notifications from sms, email, whatsapp, etc, I tried so many things, that I honestly can not say if this PNF solved the issue, but in the end my notifications became normal, so, I kept using it, you can give it a try, that is, before you reset your phone, it might help

Do you at least move your phone? Because a lot of apps, to bypass the system's optimisation that put apps to sleep, is that their wake up workaround is gyroscopic based.
That's why WhatsApp and such use a lot the sensor while it has nothing to do about in the first place.
If a battery monitor works for you, you can check that for WhatsApp.

I've just installed a push notification tester app and my phone goes into doze immediately once I lock my phone and the screen turns off it seems.
If I request a notification, it comes through with the phone unlocked but if I set a delay of a few seconds and lock the phone before it comes through, nothing will happen until I wake my screen up.
Any ideas on how to solve this?

I worked out what the problem was!
I have a VPN that is set to disconnect when my screen turns off to save battery. At the same time I enabled the Android setting that blocks all connections without VPN. Of course when the screen turns off and the VPN disconnects, my phone was blocking all outside connections, hence me not getting any notifications.

Well, I am glad you figured it out
