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.

Note 3 | 4.4.2 version|battery drain of 22% overnight.

Hello All,
I'm using note 3 France version. I notice that overnight my phone is getting, yesterday night my phone was charged till 93%and i closed all the running apps & when i see this morning, am left with 71% of juice.
Stock Android + no root.
When i look at the battery graph, it just says "android os" for 100%.
Is it actually hiding any of the background process?
Is this normal?

In my case, the sd card is the culprit. Every thing back to normal when i remove the sd card.
Sent from my SM-N9005

SD card shouldn't be a problem, many people use them without any issues, you may have experienced indexing bug, some program residing partially on a card got shot down, when card was removed, or something of this nature.
As far as OP goes, even battery display itself is weird, never seen anything like that. On mine Android OS, Android System, cell standby, device idle, something from Google and screen will show up at the minimum. In your case it seems every other battery usage had to be very small, way less than 1%, If you press on Android System, you will get more details, but no matter what I would do full factory reset to start with, since neither 22% idle discharge nor battery display is normal. Just make sure you have full backups, since you'll loose all settings and need to reinstall all programs.

Note 3 battery drain problem Solved...
Hi all..
I am using a note 3 LTE N9005. I was facing the battery drain problem with my phone it used to drain at a rate of 10% an hour even when the phone was locked and kept idle. Like some one mentioned above if I kept it aside after full charging in the night it would be around 50% in the morning.
Then i installed wake lock to check what was causing the issue but couldn't find anything unusual.
Later i noticed that my android system and android OS were consuming more than 35 % charge everyday. Even wake lock and other similar apps couldn't find it.
Finally....finally i decided to uninstall few apps one by one and check if anything changes..... and yessss..... i found it.... Facebook app and Facebook messenger were the culprits. ... particularly Facebook app.
Now without them... i am getting a full 6 hours screen time and 24 hours on normal usage. Just try it.... its worth a try.
Please note : My phone : N9005
Android version : 4.4.2 KitKat
Hope this help you.

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.

Got my new 6p two days ago. Seeing ridiculously bad battery.

Have updated until the update notifications stopped coming. Sitting on 6.0.1 with Feb patch. What can I do? I was wondering if this is a problem with stock rom and moving to something like pure nexus would help?
I searched Google (and Xda) and found there are people both affected and not affected by this problem. Any insights would be much appreciated.
Thanks!
Edit: if needed, my SOT right now sits at 2h35m58s with 30% battery left. Have screen listed at top on things using battery most with 8% and it shows 5hrs worth juice left.

The same happened to me - new phone, ran all the patches, and craptastic battery life. A factory reset fixed it.

This says nothing.
What apps to you have installed?
What widgets are running, etc?

Thanks for info! I am planning to swap stock rom for pure nexus today. It will include a full system wipe so here's to hoping. Will report findings in a couple of days.

No widgets. `Google now` and `google now on tap` turned off. NFC turned off (Wifi, BT on). Listening for `OK google` turned off completely. Screen brightness managed by adaptive brightness.
Apps include the normal google ones that came pre-installed and whatsapp, slack, apple music, pebble time, harvest (timesheet app for work), pocket, sync pro (reddit) and 1password.
I did find out that the device seems to be awake much more than the screen. Seems like a wakelock. I'll have to root the device later today and install wakelock detector to see what's up.

Over 2.5 hours SOT with 30% left isn't the end of the world. People eek 6 hrs out of this phone either with greenify or naptime or they turn all the location and background services off.
I'm at 17% with about 3.25 hrs SOT now on a third party ROM without greenify and everything running in the background. If I get 4hrs+, I'm fine with that. I have chargers everywhere.

Yeah I don't really care about SOTs and stuff. Only put it here because I thought it may help someone think of something that might be wrong. The actual problem is, I am literally seeing battery percentage go down as I use the phone. I browse a few pages on chrome, maybe 15-20 minutes and my battery goes down 6-7%. Neither of my previous phones did that and none of them were known for their good battery life like nexus 6p. That kinda has me concerned.

I'd advice you to charge your battery full (leave it on charger for 30mins after it says that it's full). Then use BetterBatteryStats background while you use your phone normally all the way down to 10%.
Take screenshots from BetterBatteryStats and from battery (from settings).
There are quick toggles for Wifi and Bluetooth, no need to keep them on constantly if they're not needed. Bluetooth is known to drain battery for some users (not me though). Screen brightness is 100% with adaptive brightness? Are you always in a well lit area? I use 50% w/ adaptive. I usually get something between 4.5 to 6 hours of SOT.
Pebble time can be your drainer, I remember ppl complaining about it a while ago.

So I flashed purenexus with elemental x. It probably is better to let it go for a few recharge cycles before commenting but things are already looking very good For anyone looking at this in future, I suggest a minimum of system reset (or flash a new rom if you wanna go all the way).
I'll monitor the battery life over this week.

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

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?
