I've done a search but can't find anything to do with my issue. I am running L26LEOV2.1_GoldEdition_213_WWE_21899_SE and have been for probably a month. Everything has been running excellent. I've got AS pushmail, weather etc all running and had no issues.
All of a sudden the battery life has disappeared. Noticed my battery at ~30% last night which was strange as I usually charge every night or 2nd night but it's never that low. After about 45mins it was at 8% just sitting idle (no data or anything running).
Did a full charge last night before going to bed and unplugged it. So 100% charged. This morning I found the phone is off, turn it on and its on 0% then shuts down again due to no power. Would only be like 6-8mths old.
I haven't made any software/ROM changes in weeks so I'm fairly sure it is hardware related. Before I go back to stock ROM and send it in for warranty work, does anyone have any suggestions for things to try beforehand? I don't want to go back to an old Nokia while I'm waiting
You could try BattLog to see where/when the rapid power drain is occurring. I've had my battery do the same thing once. I usually get through the work day with 50% left, but one day (without any use) my HD2 was dead before lunch. The problem went away as mysteriously as it arrived. So maybe just give it a few more charges and see if it works itself out. I'm curious if you've noticed any unusual ammount of heat from the battery? It could very well be that it is failing.
I'll try that program but oddly enough today its been ok, using only 10% with a bit of google maps and phone usage in about 10hr.
Hey Guys,
this morning I woke up to a dead phone again. Which was odd, because i charged it to 100% a couple of hours before I went to sleep.
When I turned it on and plugged it into the charger I immediately went into the battery usage log and took these screenshots.
Now, I heard of problems with the N4, the battery not being the best and all, but is it normal for the phone to discharge in that time by just lying around?
Also, when I plugged it in, the displayed battery level climbed somewhat fast. It had 1% when I plugged it in and 10% a minute after that. While I write this, it's at 20% already.
Is this anything out of the ordinary or am I just imagining it?

Have you installed any new apps lately?
I'm betting you have a wakelock that is preventing your phone from entering deep sleep.

Let's see... I installed UCCW (not used yet), Light Manager (changed LED settings slightly) and Fast Reboot.
Could the Light Manager be the problem? I'll go ahead and check those battery stats anyway...
EDIT: Oh, I also recently set up face unlock (stock feature) Should not be a problem though, since it's not an additional app, right?
So, after running on battery for a while I took these. Can you make any sense of it?
EDIT: Wanted to check the stats again after I had on battery for the night and it was dead again. Unfortunately the stats seem to be deleted when the phone restarts (or maybe when it's plugged in).
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?

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.
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'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.

I just started getting it since updating to 6.0.1 PN. I switched to AK Synapse and it drastically reduced it, but it is still there. Only info I can find is much older phones. I am using an LED manager...wonder if that could be it. May freeze it this week and see.

I believe that wakelock is from charging. I don't know why but the device doesn't seem to register as deep sleep with better battery stats when fully charged and then idle but still plugged in. Likely an issue with the program and not the phone.
However if you want to test this simply charge your phone over night. Once it hits 100% it will stop charging at some point and go into sleep mode. The device is still plugged in but won't charge anymore. Device will use power, mine is usually around 95 or 93% when I fire it up and use a little juice in the morning. During this time the device uses battery quickly until it drops to 89% or so then normal discharge rate. This is normal of most android devices I've had and most everyone here is aware of this:
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
Getting back to the wakelock issue, f you check better battery stats this wakelock shows up under the above condition. You'll notice the time on this wakelock is usually the sum of the device on but screen off time and your screen on usage or pretty close to it.
Now charge your device to full while waiting for it (as in not going to leave it for 4+ hours on the charger after it is full). Once it stops charging at 100% pull the device. Use as normally.
Now the device is fully charged. Really this time and not just the UI telling you it's full. When you use it throughout your day and then check better battery stats you'll notice the wakelock is no longer there or nearly so depending on how fast you got the device off the charger after it was full.
End result is this seems like a reporting issue with better battery stats or the device not fully going into deep sleep while being plugged in. I would tend to lean on a reporting issue as discharge time seems about normal at 1% or so per hour while idle and that tends to hold true to my regular doze discharge.
TLDR:
This seems more like a reporting issue than actual wakelock. Any significant battery drain when fully charged can be explained by the link above and testing as I have explained in the post.

The only thing is this wakelock doesn't start until after I unplug it and leave for work. It grows during the day..so is it faulty reporting? Something is using my phone when idle for about 2 hours a day with screen and sync off at 384 Mhz and that wakelock usually shows at about an hour and 10 minutes or so. I have also done as you said and after it dropped to 97% charged it back up and pulled it off immediately..same wakelock and similar time. Also this wakelock was not there with 6.0.0. So Google changed something with 6.0.1 that brought this to life for me. Also interestingly, this wakelock was at about 4-6 hours with stock kernel. I changed to AK kernel and that is what made it drop to about an hour and doubled my standby time.
OK, I froze Light Manager with TB and this wakelock went away. This was the only new thing I added to 6.0.1 to get the battery fully charged light to not change until 100%. Stock changes it at 90% for some stupid reason. So if anyone is using an LED manager, try removing it for a day and see if that makes this wakelock go away.
so here is the source. Are you guys all using the stock charger that came with the device? Only reason I ask is because I didn't start seeing this until I started using a samsung charger with a micro to c adapter.... I think
Reported at 93% it's my highest wakelock. Stock charger and no LED manager installed. Other causes or fixes?
I too have this at the top of my wakelocks. Did anyone else find a solution? I don't have any led managers
