Stock 5.0.2 Not entering deep sleep (With Screenshots) - G2 Q&A, Help & Troubleshooting

Ok, so my g2 is simply not entering deep sleep so the battery is draining like crazy (I lose 20%-30% when just leaving it from fully charged overnight).
I want to know what is the likely cause of these wake-locks as I am reluctant to root- (still in the vain hope of an update from LG )
At first I checked the normal battery information and found that 'android os' was keeping the phone awake and was using 49% which can't be normal.
So I installed betterbattterystats and this confirmed that something was causing the phone to stay awake when the screen's off. (the deep sleep percentage is when I switched off WiFi altogether to test it).
Obviously I can't check the partial wake-locks section as I'm not rooted.
And also, if I do have to root - how easy is it? Is it as simply to use towelroot or something similar, and how easy is it to go back to stock (if lg get their act together and push an update).
Thanks

Hard to tell from current evidence, but i can tell you that you have no benefit from Greenify. I get 30hr standby + 3-4h sot + wifi on 24/7 + 1 year old battery on 5.0.2 no greenify
Facebook app used to increase my battery drain, maybe its that if you have it (messenger is ok)
Can you check your Auto-sync settings and GPS?

I used to get those battery stats, but its only recently that my problems have happened
It shouldn't be Facebook because that app doesn't even show up in battery usage- its just 'android os' that uses over 50% on a regular basis.
I don't have messenger any more, gps is always turned off and my synced accounts are

Hi, You can try Dorimanx's kernel, you can find it here: http://forum.xda-developers.com/showpost.php?p=60586770&postcount=1
I experienced better battery management and lowered "Android OS" usage with it.

root your phone
use this method http://forum.xda-developers.com/lg-...ols-how-to-install-twrp-bump-d80230a-t3072186
and check the wake-locks
and if you want to go back stock use this tuto http://forum.xda-developers.com/showthread.php?t=2432476

this may be a useless post, but i assume you already rebooted to try and clear the wakelock right? Does it happen on every boot?

Yep, I've tried that many times - and it does happen on every boot

Can any one tell me a way of rooting without installing a custom recovery?
I saw that this method: http://forum.xda-developers.com/lg-...ols-how-to-install-twrp-bump-d80230a-t3072186 also installs a custom recovery.
As from what I understand, I would still be able to install OTAs while rooted but with the stock recovery

[Q] Pretty bad battery life, help please?

I'm not seeing the battery life everyone does with the phone, and frankly I am not sure if it's a hardware or software issue.
For starters, I have excessive battery drain while on WiFi and not using the phone - about 3%/h according to BetterBatteryStats. It all seems to come from two particular wakelocks - sns_async_ev_wakelock (kernel) and WifiOffDelayIfNotUsed (partial). There is also BlockBeforeSleep but not as obvious as the other two. Also, while on data, I get another massive kernel wakelock - bman_dmux_wakelock.
Right now I have no relevant BBS or GSam screenshots, since my phone is still plugged in. However here's a screenshot of Battery Monitor Widget on a completely full charge - if there's anything wrong with the voltage or other data please tell me, my return window for the phone ends in a week -> screenshot
Tomorrow I will be going out and will use data, so I will post screenshots here and on the GSam thread. If anyone has any idea what I can do about this, please tell me - I absolutely love the phone and it pains me that I can't use it fully.
For what it's worth, the phone is running V10B - seems to be a Taiwan ROM.
First of all, I suggest you to
1. Install Wakelock Detector to determine exactly what is going on with your G2
2. Install CPU Spy to see if your G2 is even going into Deep Sleep as it should.
3. Install Greenefy (root needed) and hibernate all those nasty background apps you don't need running until you need them running.
Cheers!

Do 1. and 2. have any benefits over BBS? I would also gladly use Greenify but I am not rooted yet.

All these apps have their own specific uses and purpose and can be used together or on their own.
The first two are for diagnostic purposes and the last one (Greenify) to avoid unnecessary data and memory consumption, thus saving battery.
Have you tried the obvious first? Starting from scratch by doing a hard reset?
Also I would really recommend you to root and get rid of all unnecessary boatware and to control things like boot up processes, startup items, fstrims, etc.
Good luck!

[Q] Battery Life Issues. Can't figure it out. Lots of screencaps inside.

I am running a Note 3 bought in Sweden around the 11th of December, fully stock. Never rooted or anything. I was actually too stupid to update myself to MJ7 right when i bought it before finding out about the KNOX-debacle, but nevermind about that. What is done is done!
Batterylife has so far been alright since I bought the phone. I've managed to get around 7 hours of screen-on time in the exact same environment as these pictures have been taken in without enabling any power saving modes or going to extremes with turning off location services etc. I was very happy.
Yet lately I've been seeing that my battery life has started to get worse. I've noticed it mostly when the phone has been idle. This led me to experiment today. I've experienced the Android OS bug earlier, which caused me to factory reset the phone and start again. It disappeared for a while, but it has come back now.
The reason I am making this thread is that I cannot for the life of me figure out what inside Android OS is wakelocking my phone. I have a lot of pictures detailing my battery stats screen, with screen on times, signal strengths, location settings, google now settings, better battery stats kernel/partial wakelocks/other tabs etc. Even "Wakelock Detector" with all of its tabs are screencapped.
The wakelock times within better battery stats just do not add up to the "Android OS" wakelock time. Is there something I am not seeing, or is it maybe because I am not rooted that I cannot see more detailed info about what is wakelocking my phone? The only thing i've done today which I know wakelocks my phone, is listen to music for about 2 hours. Surely music does not count into Android OS? It is listed as another process in the battery stats..
Anyhow, if anyone has time to take a look at my screencaps to try and pinpoint what it is exactly that adds up to the "Android OS" time, I would be very greatful. This is very frustrating, as I was very sure to disable almost everything that has to do with location services etc. to see how the battery would fare during the day.
Please help me!
Thanks.
i have exactly same problem like yours. my main wakelock is resume_wakelock and sec battery monitor. i dont know what cause those 2 wakelock. i had disabled all location services and turn off gps and auto sync. do u managed to overcome this problem ?

try and turn of (auto network switch) it might have something to do with wifi
i may be wrong ,but no harm in trying
Here the same problem, it drains my battery in half a day
installed wakelock detector, and found out, that my note 3
never goes into deep sleep, it stays awake the whole time
For me it has nothing to do with screen -on time, Wifi or any apps
the problem is is in the android kernel system, and I do not know, how to solve this problem
last statistics : CPU time 3 u 11m 24s , Awake 10 u 28m 48 s
Tried lots of "solutions" found here on this forum, but so far no good
correct me if i am wrong, but as I understood, HTC and LG are having the same kernel / rom,
but without the google "apps", and are not having these problems
Asking Samsung is no use, a concreet wall will answer you sooner, than Samsung in the Netherlands
I wished I had a solution for this android kernel problem
I will wait for the Kitkat update, and if it will solve this problem, if not I will get myself another device

you tube has a lot of videos how to perform a factory reset or how to install stock firmware
T-mobile has a nice manual also http://support.t-mobile.com/docs/DOC-9049
when re-installing the (original samsung ) stock firmware , knox will not be tripped.
I even switched from T-mobile MJ6 to provider free firmware MJ7, without any problems,
hopefully MJ7 will get Kitkat sooner, than MJ6

Hello EddieN,
Found this on the forum, Under Apps > Settings > Wi-Fi > Menu > Advanced there are two options that should help this: "Keep Wi-Fi on during sleep" and "Always allow scanning" I set the "Keep Wi-Fi on during sleep" to Never and unchecked Always allow scanning and rebooted the phone. This stopped my battery from draining fast, however this is not the solution where was hoping for, maybe Kitkat will solve the problem
kind regards

Hello, thank you for the tip and happy new year!
I tried it, but it didn't work. Wifi is on all the time since the phone never sleeps. I just checked my phone again, and it's been on for about 4 hours. It hasn't entered deep sleep not even 1 minute out of that time. This is getting ridiculous. Screenshots from BBS are attached. As you can see, Kernel and Partial Wakelocks just don't add up to the "Awake" time.. Why is this? What is keeping my phone awake?
I'm seriously getting desperate. I'm considering just tripping knox and dealing with it properly with a custom rom/kernel combination that rids the phone of these problems. Is KitKat due this month? Or is it february? I may wait for it but something tells me it wont solve the issues we are having.
Cheers

yes. finally my battery life back to normal. just updated to the latest firmware in my country and do a factory reset in recovery mode. now no more drain like hell but still android os consume about 10-15% but sec battery monitor and resume wakelock no more on top in wakelock detector. i also can get about 7hours 300min screen on time with 1day standby time

[Q] [SOLVED, kinda] Weird battery drain for no apparent reason

Hello all,
I own an international N9005.
Up until recently, I used the stock Samsung ROM with good battery life.
A couple of weeks ago, with no apparent reason, I started getting horrid battery life - in access of 10% drop -per hour- in idle (as opposed to 1-3%).
I removed more-or-less everything, disabled more-or-less everything but nothing seems to work.
Got root (there goes the warranty) tried looking for Wake-locks and nothing. The Note3 is 97% (!!!) awake even with everything disabled, and in the wake looks screen both user and kernel I only see 1-2 minutes (!).
Tried resetting the ROM, tried installing other custom ROMs (X-Note, Omega, etc). Nothing seems to work.
Currently I'm running Omera v20, with *zero* applications installed (including all the Google and Samsung applications beyond Google Playstore) and all external services (location, WIFI, et-al) disabled, my note 3 is still 95-99% awake, and the list of wake lockers is, errr, empty.
FWIW I'm ~100m from the nearest cell tower.
EDIT: According to battery meter, Android OS is keeping the phone up.
Any ideas?

Indexing your external SD maybe?
You could try the link in my sig and try again for your custom ROM.
First, thanks all for taking the time to answer.
I'm thinking about getting a new battery, but my gut feeling is that its not the source of amazing battery drain - ~20%/h while completely [!] idle (auto-sync/location/etc completely off).
I've attaching /d/wakeup_source in excel format sorted by count and total time - in-case someone has any idea what's completely broken.
As far as I can see, qpnp-vadc-ebd30a00, sec-battery-monitor, mmc0:0001:2 are the main culprits.
nicholaschum,
Before I attempt a complete wipe (as opposed to the normal wipe data / cache), how can I detect if someone is indexing my sdcard? (which may account for the mmc0:0001:2 in the wake lock dump).
- Gilboa
I know this is a long shot but try turning off developer options if you have it turned on(especially force gpu rendering). Somehow I found out that when I turned it on and the screen is idle. I get a battery drain. Not as big as yours. But not really sure because if I use the phone, the battery is actually pretty great(an hour of screen time is about 10% even more with internet apps like facebook youtube chrome etc.).
Clear cache. I know this is too common but it actually works for a lot of people.
Lastly, try airplane mode overnight and see if it doesn't drain. It might be your network that is causing the drain.

Hi, basically just check your phone using BBS (BetterBatteryStats), and see which individual process is eating up your battery.

Already installed - together with WakeLockDetector.
Short update, out of pure desperation I completely wiped the phone (including sdcard), tried installing stock ROM and, err, Odin failed. Managed to get CWM running again and installed the latest CM nightly.
...
As weird as it sounds, going from NF4 based ROMs (including stock) to CM nightly dropped to idle battery usage to ~2-6%/h, a huge drop from ~20%/h.
I'll update and mark resolved if this situation holds (crosses fingers).

I heard there were problems with NF4 battery. But I haven't been on TW since ND4. No matter what on Note 3 TW the battery sucks. AOSP is great. But actually S5 port has the best battery.
Solved, at least for now.

I use Nova (and not TW)
Either way, latest nightly seems to solve the battery drain problem completely - using the same Nova and system configuration (widgets, active syncs, etc). Currently I'm at ~1.5-0.8%/h when idle with no issues going into deep sleep.
Seems that my specific model really dislikes NF4.
Thanks again for trying to help.
This thread has been quite helpful as I was suffering with a Battery Drain after the NF4 Upgrade.
Planning to go back to ND5, which was the last stable version.

I was thinking about doing the same, but in the CM 11 runs circles around both NF4 (duh!) and my previous ROM (not sure which revision it was) - plus I can actually get 2 days of standby time, even with the old batteries, so I'll stick with CM 11 for now.

Good luck, and post if you find a solution (in-case I decide to switch back to Samsung based).

100% Awake, Lollipop. Better Battery Stats Kernel Wakelocks "File could not be read"

100% Awake, Lollipop. Better Battery Stats Kernel Wakelocks "File could not be read"
I've had my Samsung Galaxy S5 for over a year. A while back I updated the OS a couple of times, and now it's on Lollipop (5.1.1). Lately the battery life is very low, although I don't think this started at the same time as the upgrades.
I've tried to use Better Battery Stats to figure out why. It concurs with the Battery control panel that my phone is staying Awake all of the time, never in sleep mode. Most of the time is at the 300MHz cpu speed. Unfortunately when I try to view the Kernel Wakelocks section of BBS, it just says "File could not be read" and presents me no statistics. I was using an old version of BBS, and have just updated to the newest version and this behavior persists.
According to the Battery control panel my top consumers of battery life are Android OS (10-20%), Android System, Bluetooth, Screen, Google Play Services, Cell standby (2-5%), and then a bunch of apps at <5% each.
How can I find out what is keeping my phone awake?
(If your answer involves rooting, I'd appreciate a link to a howto that doesn't require a computer running Windows)
(If your answer involves rooting, I'd appreciate a method that works on Lollipop 5.1.1, not stock S5 with Kitkat 4.4.2)

There is an application called Wakelock Detector to find out what's causing the problem you mention, but it requires root. If you don't want to root, you can try this:
Turn off your phone, and then turn it on pressing and holding Volume Up, Home, and Power button at the same time until you see a warning. Then press Volume Up to continue, and navigate using volume keys and select wipe cache/factory reset with the Home button, after that select wipe cache partition and do the same, finally reboot.
Please note that by doing this all your data will be lost.

I'd love to root, if I could find any method that works for Lollipop on the S5.

Clear cache of Google Play Services.

Just cleared its cache and will see for few hours.
By the way I'm thinking of trying this if the problem persists: http://forum.xda-developers.com/general/general/fix-fix-systemupdateservice-wakelock-t3060548
Edit: Clear cache not helped.

Android OS consuming huge amount of battery

hi guys first of all i apologize for this post not having detailed info such as ss from BBS,GSAM and WLD and will post them later !!
and as always i guess with most battery related problems it happened suddenly and i really mean suddenly the day before yesterday everything was perfectly fine and i didn't have that ridiculous battery drain !!
i woke up yesterday only to find out that Android OS is taking more than 50% of battery usage with a drain like 20% over night
restarted many times and by the end of the day i installed GSAM and WLD (wakelock detector)
froze most of apps including the ones i installed recently but i didn't install that battery hog apps (nothing unusual) and also they didn't appear in partial wakelocks section of BBS
btw i don't use any fake battery extender tools or memory boosters it's just Greenify
i observed that sometimes when i unlock my device (i use knock code btw if that matter!!) wifi gets disconnected and reconnect again (wifi icon disappear and re-appear again in 3 secs or so)
i'll upload ss in a couple of mins
thank you
Edit: SS Added
and notice how it drained 5% in just 40 mins (20 mins SOT) !!!

yea almost identical problem
i did tot reinstall and see how things go !!
sadly nothing changed and wifi still eats huge amount of battery idk how did this happen
well i'll update thread if anything changed
peace out guys
I had the same problem with battery drain(although not as severe) along with huge data consumption when using a significantly modified(i.e. heavy debloat and ota disabled) rooted stock rom. I tried a few customs roms and dorimanx kernel(not at the same time), and even though battery drain wasn't as bad, they were are waaaay to buggy to be used everyday(especially the dorimanx kernel, it's really bad).
Just last week I tot back to KK and ota updated to the latest LP rom(lost root unfortunately). Then I uninstalled/disabled every app I could/needed. Everything is very fast, smooth, and stable again. I now lose 1-2% every 8hrs in standby with syncing and wifi/data enabled, bluetooth and nfc disabled. I regularly get 5-6hrs sot over 48hrs with moderate use and brightness on auto.
I do have a new battery though - my old one( came with my "refurbished" phone from freedompop) gave me 2-3hrs of sot - but that was when I first got it and before I started modifying anything.

How is dorimanx kernel bad? How many user downloads he has,lots and lots then are we thousands of user wrong using a bad kernel, come on . Maybe it didnt work for you. But out of those thousands of users cant be wrong. If it was that bad no one would download. Just saying , you should just say it didnt work for you.

Can you tell us what app have you uninstalled and disable ?
What have you debloat ?
Thank you very much
My G2 (vs980) has also been suffering from a sudden battery drain. Android OS and Android System seem to be the problem. They are now second and third on the list of battery usage, after the screen. Before now, they were never that high on the list. I noticed this last weekend, when I kdz to the latest update for the vs980, which is 3AA. After noticing this, I flashed the xceed kernel, then cloudy with dorimanx kernel, and the battery drain continued. I even kdz back to kitkat, still the same, then I flashed AICP 11, and still the same battery drain by Android OS and system. Finally, I restored a backup of stock lollipop 39A but, the issue continued so I turned on airplane mode and it seems to help a bit. I still notice battery life isn't the same as before. The os and system still drain more than usual even on airplane mode.
Kind of glad to hear I'm not the only one with this issue. I don't think I need a new battery, since I bought the phone new in April 2015 from Bestbuy.
Also Gsam, shows the temperature of phone between 80°-90°F, where before it would be in the low to mid 70s. One time, it even got up to 104°F, funny thing is, it doesn't even feel that hot in my hand.
Hopefully, we can find out what's causing this because I really liked the battery life on this phone. Even when people complained about the battery life being worse on 5.0.2, I was pretty happy with it. All my previous phones can't compare to the g2. Now I feel like upgrading though lol.

When I tried the version that was out a month or two ago it wasn't nearly as smooth as stock, even after conservatively messing with the kernel app settings. The worst was that it also cut out tethering and my flashlight when the screen shut off. Maybe the recent updates have fixed some of the issues, but I doubt it. Could be that he doesn't have access to the sprint variant which I have...
Either way, just because 'thousands' of people use it doesn't necessarily mean that it's good - 99.9% of those users have no idea how to code or how a kernel is written. Their knowledge goes as far as following picture guides online - which a 5 years old could do. Just look at the most recent change log - those 'fixes' were to glaringly huge problems that shouldn't have been made in the first place and people were blissfully using it the whole time. Think about how many thousands of other bugs their must be. Not to mention hacking up code made by professionals at huge companies could lead to many other problems. Obliviously the stock kernel has bugs as well, but it works and is fast and stable so I see no need for using a hacked together kernel made by one amateur that doesn't even have my version of the phone to test it on. I wanted it to be good - which Is why I went to the trouble of installing it, but it's definitely NOT.

I uninstalled ALL of the stock apps that can be uninstalled. The ones I disabled are aosp keyboard, app updates, browser, calendar, cloud print, favorite contact widget, google play books, games, movies & tv, newstand, google+, lg voice command speech pack, music, music(the widget - it always runs in the background even without being on the homescreen), notebook, polaris viewer, quicktranslator, swype, talkback, voice command. I would have liked to disable a few more but I'm not rooted so I couldn't.
I use nearly all of the google products like chrome,gmail, calendar, docs, keep, music, photos, news and weather,translate,etc...so having the stock lg ones enabled was redundant. I also only have the bare minimum of installed apps that I need. Nearly all of them are made my major corporations i.e Chase, BofA, ebay, paypal, freedompop, microsoft, swiftkey etc. I have NO games or any small apps that need a ton of permissions. The only small apps are feedly, print hammermill, privacy flashlight(240kb, no ads, no permissions) and bubble level(180kb, no ads, no permissions).
I also go through every settings in every app to make sure it's what I want. And I restart my phone every time I take it off the charger. IMO having a clean and no frills system that is set correctly is the key to performance and battery life.
I just want want to clarify that I average 4-5hrs per 1% in standby since it doesn't seem to hold as well as it gets closer to 0%.
theres this app that have lots of info on battery..
thx guys for adding your experience
i hoped moded kernels would've reduced that amount as they should have necessary drivers for wifi which was somehow got messed up but from your reply i guess i've to look somewhere else
idk how to put this, well this isn't a solution at all i actually didn't start working on it yet just thought to share what i found so far !!
so it's just a reference for any one whose luck was bad enough to have a wakelock like that !
1st of all in most cases neither the device nor it's battery are at fault *you need to understand that*
faulty battery doesn't show up kernel related wakelocks instead they drain without a reason so i hope ppl stop accusing battery in every battery drain thread!
2nd after understanding that you'll have to deal with the environment your phone is used in
to put it simple it's your router and all devices in your current network !! (idk though why not all devices get affected by that or why it just started now, tough luck yea)
those threads may help

http://forum.xda-developers.com/google-nexus-5/help/getting-rid-wlanrxwake-wakelocks-t2519294
what i'll try to do is add an old access point to my router and connect my phone to it as i don't have a replacement router right now!!
i'll let you know if things were improved !
hey guys
i thought to share what i did so far and before i go on there is a bad news and a good news !!
i would start with the bad news first !
-no rom could solve this issue so you don't really need to format everything and start from scratch especially if you didn't mess around too much and you found it started suddenly like here, i've tried couple of roms including latest CM13 build it wasn't that bad but it didn't solve the drain that much either !!
-now some ppl may see this bad and some may don't care (which means good!!) google services are the ones responsible for this drain
well man you didn't come up with anything new and i see you've got a problem getting straight to the point besides you talk too much
i'm sorry
now you have to sacrifice your google services background sync including "GCM" if you are using any services similar to pushbullet or notification mirroring you'd understand why it's important
anyway if you are good with that you may install and yea it works with latest google play services
https://play.google.com/store/apps/details?id=com.playfulgeeks.gservicefix
and do as instructions (and believe it'll work if you did steps right)
if you prefer manual way then you'll need "app ops xposed module" and deactivate every "wake up" permission from google services
this guide may help but remember we don't have tools natively in our roms so don't bother downloading "shortcut maker" and go through your settings app to find "privacy guard" or "app ops" we don't have those natively like them
http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525
i'll share some ss from stock battery stats
i'm sorry for my long post and i hope it'll help someone with same issue
idk if it solved issue completely but things are stabilized a lot now and i just lost 1% over night not 20% or 30% like before !!
and i'm using lollipop now so i guess it's not that bad for what i heard about bad lollipop battery since it's my first time trying it !!
and btw real SOT should be +40 mins so the real SOT is 2H-47M cuz i restarted my phone to apply that fix and for some reason battery stats doesn't stick between reboots !!
if anyone interested in trying that rom it's for D800 only btw and thx to @Swetnes for his work rom feels pretty stable and solid :good:
link: http://forum.xda-developers.com/att-g2/development/rom-t3152368/
good luck everyone
