Excessive Deep Sleep Battery Drain

Some of you may have noticed that battery life on this phone can be both unbelievable and mediocre. I've been trying to figure out what can trigger and cause mediocre performance and I'm at a loss. The problem is, there doesn't appear to be a smoking gun. No obvious wake locks. No rogue Apps. I have Carrier IQ disabled by System Tuner. Google Now is off. What I'm running right now is pretty bare bones. And the kicker is my phone is sleeping, as can be seen in the shots below. The vast majority of the time my phone was off the charger it was in deep sleep mode.
I noticed my phone in excessive drain mode Saturday so I let it run over night and into the next day, so that BBS and GSam could pick up as much data as possible, including sitting idle overnight and very little use throughout yesterday.
Here are some shots to show the story. The graph, which is definitely steeper than when idle drain is normal, which resulted in idle drain of about 6% per hour. Also as can be seen in these shots, there is not a wakelock problem. Deep sleep shows as 12 hours 38 minutes, Awake time of 1 hour 8 minutes, and screen on time of 1 hour. So, my phone was only "awake" for 8 minutes when the screen was off out of almost 14 hours according to BBS.
I did notice and oddity here though. BBS listed the unplugged status as 13 hours 47 minutes, while the phone's battery meter listed it at 12 hours 13 minutes.
Attached are the shots I took at 19%, as well as a final battery meter shot after charging the phone to full while powered off and restarting, where it's been purring like a kitten in deep sleep.
Part of me is beginning to believe there is a bug with the battery gauge. What do you guys think is going on?

Try clearing data for google play services,google services framework and playsore than reboot and check if things changed.
And i would recommend uninstall the updates related to those apps and let them update itself again.

Done. Although I won't know if any attempts to resolve the issue have worked until the idle drain triggers again (or doesn't).
Thanks for the advice.

Well unfortunately that didn't solve the issue. The heavy deep sleep drain again triggered after a bit over one full day. I charged to full last night and let sit over night where it drained 6% per hour with no obvious culprit. Anyone else have any suggestions?

It seem that your signal is week, did you get stable signal and have you tried airplane mode, to find out how much battery drain in this mode?
Also, did you disable LG MLT? This is a massive app from LG, can consumed about 150 MB RAM.

This might sound boneheaded, but what about just resetting the phone. Maybe some system app is causing some type of memory leak and thus draining your battery. Also disable wifi when you're not using it.

I don't think it's signal related. I get an excellent signal at work and the idle drain still occurs. Also, it happens whether wifi is on or not. I have not disabled MLT, as I'm not concerned about RAM, just running processes. Rebooting the phone eliminates the issue, so something is obviously getting hung. The really odd thing is I was draining 6%/hr overnight, all while the phone was in deep sleep, yet my top battery consuming category was the screen at 35%, with just 1 hour of screen on time of 10 hours off the charger. If something was cranking in Android System that caused 40% drain overnight I would have expected Android System to be higher. It doesn't make any sense.
I may just have to factory reset.

My battery's been great until couple of days ago when I turned on GPS and Voice Notification (for speaking out names when phone call/message comes in). After I noticed the abnormal battery drain, I turned off those two options, because that's the only thing I did differently before noticing the drain. However, that didn't help... yet. I needed to do a reboot and battery's been fine again. Not sure if those two were the actual culprit, or just coincidence.
Have you changed any settings right before you noticed the drain? Just a thought.

had the same issue., wakelock detector, BBS, GSAM nothing could show what was eating the battery. i use mobile browsing a lot and almost 8/10 times this battery drain was happening with chrome , chrome beta and firefox browsers.
Only thing thats helping me is the Greenify app . Greenified the chrome and firefox and almost all the cloud apps and the battery is now much much better.
still ...IT IS AN PROBLEM to be found..

To provide a bit more info on this, attached is a pic of my reboot a couple hours ago (marked by the thin white vertical line). The change in the slope of the drainage line is drastic. Also, notice the small hump after the reboot? The line actually increased a bit, fell, then flat lined. More and more I'm beginning to suspect the battery gauge, but I just don't know.

I have the same situation after charging. Even in"deep sleep" it would chew through the battery. Now I just reboot the phone after charging and it plays nice. The gerbil on the wheel seems to take a break and rest.

To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.

i got the same issue which is very annoying, have over 85% deep sleep, no wake lock, battery draining like crazy, and it happens randomly. I wonder if factory rest fixes the problem, or hardware issue
i have done a bit testing for this random drain,
with mobile signal on ==> huge drain
without mobile signal on and only phone signal ==> huge drain
airplane mode ==> no drain
so i believe it is a bug within the phone software, actually sometimes the random drain started after a phone call

I've been getting the drain too in the past few days. Last time i could fix it by factory resetting, but obviously I don't feel like doing that once per month. What I do know is that flashing another stock ROM (kdz) without factory resetting doesn't fix it. However last night I figured i'd try disabling WiFi (kept it on during the night until now) and I only drained 1% in 5 hours, down from 3% per hour. Perhaps this bug is related to WiFi.

Have you disabled LG MLT? It acts like CIQ for internal LG purposes. I have personally seen it cause mass wakelock in unexplained situations. If I leave everything on overnight under 95% battery, I will get around a 3% drain in about 7 hours. Pretty normal. The first 5% on these batteries seem magical. At 100%, with everything on, I wake to 100%.

Yup, frozen in TiBu. Will be factory resetting however when I get home as GSAM grabbed my attention. Never were system things so high up the list when i had no drain.

I been struggling with this since I got the phone (almost a month now). I've done all the usual:
Removing bloat
Disabled CIQ
Disabled Google Now, Location, GPS
and I have the same apps as my Nexus 5
Just last night I realized that this battery drain only happens after taking it off the charger. This got me to add the word "charging" in my search and I found this thread.
Is this hardware related, or would a custom ROM resolve this? I have the AT&T version.

Ok and which stock rom does not do that?

Probably this is a software issue. Never heard this problem on latest firmware or custom ROM.

Guys could you write which stock rom does this wakelocks for you so we could eliminate corrupt firmwares?
For example I experience these wakelocks on latest F international version.

[Q] sudden drop in battery life

I've got the 16gb nexus 7 (non 3g).
I've had it for less then a year and the battery life had been great. But starting over the last few days the battery is horrible. After a full charge over night my battery was down to 50% today. And that's with hardly any use. I used it for maybe an hour total and at least half of that time was just reading reddit.
I haven't changed any settings recently. This is all stock, no mods, not even rooted.
The battery usage right new says it's been 13 hours, and it's down to 48% and Android os accounts for 27% Followed by screen at 18% and WiFi at 9%. Those are the top 3 showing for battery usage.
Any suggestions as to what's going wrong it how to diagnose be fix it?
Thanks

Either your battery is bad or you have a stray process running somewhere.You might want to factory reset it, possibly even reflash your image.

Would the battery go bad that fast though? In my experience batteries usually gradually get worse. This went from losing a few percent of power to losing half power in the span of a day.
I might try the factory reset - just have to make sure everything is backed up. This tablet isn't rooted so i dont have titanium backup on it.

Doubtful it's the battery... my money is on a rogue app!!!
Hi, merkk...
It's possible, that as the previous poster suggests, some rogue app is 'eating' your battery.
The biggest consumer of power is the screen, so ensure you haven't got it set it maximum brightness... and ensure auto-brightness is enabled in settings.
Another thing you can check, is your WiFi setting... on my Nexus 7, I have 'Keep WiFi on during Sleep' set to 'Never'... it's not a setting that is easily found - it's buried in SETTINGS>>Wi-Fi>>overflow MENU (three dots, top right hand corner)>>ADVANCED>>Keep WiFi on during Sleep.
It also might be worth checking if the SYNCING of your respective accounts (Google, Twitter, etc.), haven't been inadvertently changed. Particularly the SYNCING of your Google account... which by default, SYNCs a lot of stuff and frequently. This will keep WiFi awake, and may cause battery drain. Go to SETTINGS>>ACCOUNTS>>GOOGLE and disable what you don't need to be SYNCed.
-----------------------------------------------------------------------------
It's unfortunate that your Nexus 7 isn't rooted, because there are a couple of excellent diagnostic apps available (GSam Battery Monitor and BetterBatteryStats) which provide more granular and finely detailed battery info/history than the standard Android battery info screen... and are useful for tracking down problematic apps that might be keeping the device unnecessarily awake ('wakelocks', etc.).
However, due to changes in Android 4.4 (KitKat), these apps now require root access to read and report battery stats info.
If your Nexus 7 is running any version of Android BEFORE 4.4 KitKat (and some haven't updated yet), then you don't need root to run these diagnostic apps.
-----------------------------------------------------------------------------
It's sometimes the case, with Android, that there will be occasional peculiarities with battery performance... and in my experience, it's almost always the case, it's due to something the user did... some app or widget installed. I'm currently experiencing similar battery issues on my Samsung Galaxy S3, but having run GSam for a couple of days, I think I have the culprit identified. If I can't eliminate the problem, I'll uninstall the app.
-----------------------------------------------------------------------------
Hope my ruminations are of some use.
Rgrds,
Ged.

Gedblake, thanks for the suggestions. For whatever reason, today it seems to be back to normal. The only thing i did last night was drain the batter to around 10%, turn it off, and let it charge while turned off.
Turned it back on today,used it for about 15 minutes or so playing a game. And now just about 5 hours after turning it on, it's down to 92% which is what I'd normally expect.
I'll try some of your suggestions if the problem re-occurs.

I noticed that my N7 (2012) has been draining quite a bit lately. Watching the battery stats, it seems Google Wallet was eating up some major battery. It was 2nd at 29% with the screen number 1 at 38%.
Not sure what the heck Google Wallet was doing, but I killed it and things seem to have stabilized.

battery drain after update?
For years I've had the same routine. I use my Nexus 7 all day for work, mostly notes. In between I play, (youtube, E-reader, etc). Every night I plug it in to charge and in the morning it's fully charged and ready to go. On Tues, I received the OTA update for 4.4.4 I noticed this morning that after a full night's charge, the battery only reports 50% charge. Is this the beginning of the end? What steps should I take from here? I recently bricked by GS3 so I depend on this thing now more then ever, any help would be sooooo appreciated.

I'd just restart it and let it charge again. I've updated mine a while ago and haven't had any issues.

I'm on a custom 4.4.2 ROM and I have had intermittent draining behavior as well.
Sync is off, location services off, I turn off wifi manually, and I always clear recents before I have my tablet sleep. I have greenify installed. I'm using better battery stats.
My issue seems to be similar, but I am also having battery percentages jump around.
Earlier today it went from 26% to 43% in the middle of me using it. Without charging. It frequently does this, both lesser and greater values reported. I've had my tablet shut down in the 30% range. I've had it shut itself off on 4%. I've had it drain all the way to 0% and then some before shutting down. I've had it turn itself off and when I power it back on the tablet is thinking it is at 25% or more.
I haven't been getting much more than an hour of screen time with my tablet lately. Clean fresh install of my ROM.
But I've never, until the last couple of days, had it go from a small percent to a large percent active during use. I took screenshots. I even started a thread to talk about it but nobody has responded yet.
Has anyone else ran into this behavior? Is it a sign of a soon to be dead battery?

mine got almost 30% drained on idle, airplane mode, screen off for 3 hours (tested on stock rom 4.4.3. GApps + Swiftkey + BBM + Facebook only)
my nexus 7 never lasted a day, only half a day max.
trying GSam app, hope it helps in knowing what's eating up batteries.

S4 major battery drain

Hi guys so I have a s4 i337m running Android 5.0.2 and recently I have been getting extreme battery drain. It draims around 3% an hour when the screen is off and seems to be awake more than half the time! I can get may even 2 hours screen on time even with my 3000 mah zero lemon battery. I have factory reset twice and even reinstalled the rom and it if anything it's gotten worse. Any ideas.? I do think want to downgrade to kit kat unless if have to.

Not enough information from you to allow anyone to help. Install an app like Better Battery Stats, run it for a day, then post a log so we can try and help.

I have been using gsam battery monitor for a couple of days and the android settings as well. I don't now how to put pictures in this thread but android is and system are at the top. Around 35% screen 20% android os, 15% android system 10% other apps and the rest unaccounted for. In GSAM I get around 70% app usage with both android is and system taking around half that. In the system settings it also shows that I have severe wakelock. I was in an area with no service at the but that is not the problem. I am on wifi 90% of the time. And almost always have a good cellular connection when I'm not.

Phone Idle under Settings/Battery

What runs under "Phone Idle" on the V20. It's been the largest battery consumer for the last week of use that I've noticed. My wife's V20 is the same and I had my brother check his and his wife's V20.
I'm only asking because I'm not see great battery life like other have been reporting. I don't have live wallpaper, have only two widgets on the home screen. GPS is set to battery save, screen is set to auto but that doesn't even come close to chewing up the battery.
Sadly I feel like I'm still using my old 2.5 year G3 where it'll need a charge mid way through the day.

Really??
Pretty sad that needs to be done on a week old phone with minimal apps. I'm not even a heavy user.
I feel like I'm back on my old DroidX days where everything was a factory reset but never helped...

I agree with you. Although my phone is just beyond a week old and does have all my apps installed, a factory reset can't be the solution here. This is the typical "I don't know how to fix this" answer always given by manufacturers and carriers.

In the roughly 3 weeks I've had my V20 I've only seen this once where phone idle was higher than Screen. I started looking thru all running apps for 'keep awake' time being high and noticed Android OS had keep awake of over 2 hours when it's normally less than an hour after a full day use. I power cycled the phone and it stopped.
The weird thing was Android OS didn't show high battery usage even though something was triggering keep awake. Looks like the keep awake was causing phone idle to be high.
I'd look at everything in your battery usage to see if you have any high keep awake times.

Sorry did not mean to be short in my response. When you set up your phone did you restore it from another phone using the nfc bump thing? I did the same and my phone battery was the same way. Wouldn't last even half a day. After i factory reset and set everything up manually i get 18+ hrs with 7 hrs screen on time sometimes.
If this situation doesn't apply to you then maybe a reset won't help. But you have to understand your situation isn't normal.

Make sure Google now features are all turned off and not running in the background.

I'll have to go through the apps one by one like I did previously on my G3 and see. Now within the battery stats there is only a handful of apps like hangout, play music, chrome and camera. The rest is OS related so that's why I was curious what ran under Phone Idle.

No and sadly I was looking for that feature a week ago but couldn't find it so I had to individually install most of my apps I had on my previous phone...made for a long night along with the additional emails and configuration or icons and such.
I'll keep digging away at the phone...I really want to like this phone ?

Has there been a definitive resolution to "phone idle" battery drain? I just got a V20 2 weeks ago on sale for $360 and its a fantastic upgrade over the One+1 I've been rockin all these years, but I'm also suffering from mediocre life due to whatever phone idle is. Some forums (for other phones) say phone idle is related to your wireless signal. I'm still with the same carrier and frequenting the same locations and had no such battery drain with that old One+.

i finally discovered whats was goin on with me..
i had the same issue..
phone idle was topping my battery usage list
it turns google plays have this "locationmanager service " and locationwhatever" that kills your battery over wifi even with location button off

Go to locations/ 3 dots in top right corner/ turn off WiFi scan. See if that helps.

My phone has been suffering from poor battery life for quite some time now, here are the screenshots, Android OS has been this high on almost all battery cycles.
I disabled wifi scanning as suggested above and will watch the performance, does the community have any other inputs to fix this? View attachment 4212978View attachment 4212979

Phone idle is always the biggest battery draw on my phone too. I have minimal apps too. No Facebook or similar types of apps. I'm on a Verizon V20 stock with the latest security update. Is this normal V20 behavior to have phone idle consume more battery than everything else?

how about doze mode , isnt that meant to help with this sort of problem ? ( my phone is currently on a ship )

Any update. İ have the same problem

So what did you do?

Would also be grateful if anyone shared a solution.
I specifically have a SIM-unlocked Sprint model (LS997) which am using in Europe with another carrier.
Using it in LTE preferred mode drains about 10-15% overnight.
Using it in WCDMA preferred mode drains up to 5% per night (yes, wifi and cellular data OFF and many apps greenified) . So I'm really interested in how this can be fixed and achieve 0% battery drain across several hours.
Or maybe it's SIM-unlocked Sprint ROM related?? I can't root my phone since it has the Feb 2017 patch and is a ZV6.
I suspect rooting it and using another ROM would solve this + the annoying issue of not being able to send images via FB Messenger and Viber while on cellular data (I imagine the Sprint guys placed some kind of restriction to deny media transfer for these apps when using cellular data).

I have noticed this too.. wondered why "phone idle" takes most battery... any suggestions would be great!

I am also curious about the solution. Phone Idle is at top. Even without SIM card. 30% drains during a night (everything is disabled, but no airplane mode is on). I tried factory reset, reinstall older ROM, replace battery, use no app but still sucks.

hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.

Note 4 Fast Battery Drain

Hi,
Not sure if this is in the right section so admin please feel free to move.
Ive googled my problem and had a bit of a read but dont really get any solutions.
Ive noticed a serious battery drain since upgrading to 6.0.1 - maybe it happened on the previous version however ive just seemed to have noticed it more since i did the update.
My battery doesnt last very long. It will show 100% in the morning. If i dont use it, it can go down to about 80% within an hour or so. If i do use it then im using apps like gmail, whatsapp / sms, short phone calls, some other apps but im not on them for very long. I normally close all apps that are running in the background.
This morning it was 100%, ive used it as described above and its on 57% and its not even dinner time yet...
Ive checked the battery usage and top of the list is " Cell standby" with 48% usage showing power used is 1530mah - which is alot. The next is "my data manager" (an app to manage data usage) showing power used is 485mah (alot less!). Ive attached a screen shot.
Ive also noticed that once the battery gets to around 30% it drains even faster. I find myself using power saving mode when it gets to about 20%. It still seems to drain at a similar rate. Maybe slightly slower.
Any ideas on what i can do to recover battery time without buying a new battery. There seems to be a few topics online relating to battery drain when updating to the latest android version.
Thanks

Thanks

Factory reset might help a lot.

Dont really wanna have to do a factory reset if i can help it.
I forgot to mention i also cleared the cache in boot mode

I had same battery drain issues when i updated from lollipop to Marshmallow but after doing factory reset everything is better then lollipop and doze feature in 6.0.1 works very well. I leave my phone at night about 9 hours and not drain even 2% battery and i got 5 hours scrern on time .
try factory reset+wipe cache from recovery and use atleast 3 days to doze feature work properly.if you have same drain issue then it's a bad battery.this is the only solution so far.

Battery pull?
