past 2-4 days.... my nexus just dies suddenly with the battery drained. checking history with system panel shows that the cpu usage just suddenly shoots up to 100%! and i dont know what app is causing it.
just updated locale and extended controls + a lot of other apps. but my main main suspects are locale and extended controls (since EC posted that they are having problems with the update on the nexus)
any ideas? any other apps i could use to target and isolate the rogue app that drains my battery?
get a task manager and see ?
also, it may just be time for a new battery. ebay. $13 shipped, 2400 mah

System Panel HAS a history, and you can see which apps are using CPU, so have you done that? Is the phone getting hot? It would if the CPU was running 100%. And even at that, it wouldn't immediately die, I've never exactly tried to see how long 100% cpu utilization takes to drain the battery but I'd have to guess it's at least 2-3 hours.

seems fine at first then when i notice its hot... it is already about to restart. couldnt even get to check the app usage on system panel. after reboot... the app usage in system panel goes away. just checked now.. nothing is eating the battery up according to system panel.
guess the rogue app just turns on and eats up all the juice at some point in time. weird.

Do you have SetCPU or anything else enabled with a performance-oriented governor or similar? That would likely keep the CPU pegged at the max without really doing anything.
Try disabling as many applications as you can until you can pinpoint which one is misbehaving.
Same Problem Here
My phone is experiencing atrocious battery life, and so is a friend of mine's. We are both on FRG83D, and it seems to have been the trigger for the problem. He is on AT&T and I am on T-Mo. My wife also has an N1 on FRG83D on T-Mo, but her phone is not having the problem. Her phone is set up very Vanilla, my friend and I have more system altering stuff on ours but nothing too wild, and none of the phones have ever been rooted. The two problem phones both use Launcher Pro and Extended Controls, I am not sure what else we have in common in our apps. I installed System Panel today to try and figure out what is happening, but I still can't find an obvious culprit. While the phone is sitting on the dock charging the CPU seems to be idling under 10% and when I pock it up and look at System Panel you can watch the CPU spike to the upper ranges if you scroll the screen but otherwise it is idling under 10%. The display is always the highest on battery usage and the worst app shows as System Panel, but that is basically what I expect to see. I am ready to start removing apps to see if I can get it back to normal unless anyone has an idea of how to better diagnose the issue.
I had this issue a while ago. "system" was taking up all my CPU, and I couldn't find any details about what was really causing the problem. I couldn't remember how I finally found out about the problem (I think I spent a night reading the logcat to see what was wrong). I couldn't even use the phone, it became horribly sluggish, and battery went flat in mere hours. Turns out, I had a bad picture or two in my SD Card, and the media indexer went in a loop trying to interpret the files. For some weird reasons, the same files got Windows Explorer "confused" too.
Try to remove or format your SD card and see if it's doing the same. I know it's more of an anecdote than a real known issue, but it won't hurt trying
oh wow i was hoping someone was having the same problem... left it overnight unplugged so far so good. now im really beginning to think its extended controls. took out the widget and replaced it with the stock one for now.
IDLING at 10% CPU usage??? Mine idle at 0% if nothing is active. Average 3% over time.
You guys should watch and see what's using hte most CPU, SystemPanel can do it if you look at the history (free for a week or 10 days or something, or buy it to keep the function), but also look at Spare Parts, you can install it from the market. It gives you visibility to a few more Android settings/info menus which you can see which apps are keeping the system awake etc, it can help pinpoint what's going on.
Something very bad is happening. When you all figure it out, report back.
When I look at system panel the little CPU circle graph stays at 100% for the most part. I don't understand if its accurate.

Do you have the app 'Extended Control' installed? The last update is very buggy and is causing bad battery life and broke the camera app on the N1. Check comments on the market. They are working on a fix.
Sent from my Nexus One using XDA App
Looks like Extended Controls
I did some testing and Extended Controls does appear to be the culprit. Dev seems to be aware, hopefully they get it sorted.
Edit-Overnight and battery life is back to normal with Extended Controls uninstalled. I didn't suspect it at first because they had already released an update after FRG83D, but apparently it was broken worse than they knew. I hope they fix it soon, I like the app.

It obviously should not sit at 100%, look and see what app is using CPU, it ain't rocket science.. Mine idles around 3% with my apps, mainly K9 and Tasker, weather etc..
Step 1: Call HTC's exclusive Nexus One Phone number
1-888-216-4736
Step 2: Tell the rep your battery isn't holding charge. (Possibly tell him your earphones blew as well, if you lost them like I did )
Step 3: Wait 3 days for the battery (and headphones?) to make it to your door.
You don't even have to ship your old battery back!
Step 4: ???
Step 5: PROFIT!
Okay, just a warning. This firmware is a battery destroyer. Within 11 minutes my battery has dropped 10% and I have no running background processes and I'm not doing anything with the unit. Just checking the screen once in a while. I've actually watched it go down 1% in a minute.
I'm telling you...if you have not installed this update...don't do it!
Too late for me.. already updated. I'll keep an eye on my battery level and let you know if I notice it go down faster than normal.
I just unpluged from the charger. It is at 100%.. I'll let you know where it is in 1 hour. I'll turn on display to stay on to simulate being used and then let it set.
Edit: Okay after 10 minutes.. still at 100% screen always on.. that was with whatever programs load into the background after boot.. I haven't killed any apps. I now have launched my Pykl3 Radar app to increase cpu from 300Mhz to 1000Mhz.. it refreshes the radar screen every 5 minutes.. we'll see how the battery does with the processor working harder.
I'm not noticing any difference really... Same battery life as before(I think, I haven't done any formal battery life tests or anything)
Seems fine for me too, but I'll go ahead and do this test.
Edit1: After 30 minutes it is still at 100%.
Edit2: After 35 minutes it has gone down to 99%
Edit3: After 60 minutes it has gone down to 96%
Edit4: After 90 minutes it has gone down to 90%
Edit5: After 2 hours it has gone down to 82%
Edit6: After 2.5 hours it has gone down to 76%
Edit7: After 3 hours it has gone down to 67%
Edit8: After 3.5 hour it has gone down to 61%
Edit9: After 4 hours it has gone down to 55%
Edit10: After 4.5 hours it has gone down to 50%
Edit11: After 5 hours it has gone down to 46%
Edit12: After 5.5 hours it has gone down to 44%
Edit13: After 6 hours it has gone down to 40%
So this averages out to a discharge rate of 10%/hr
This test was done with the screen fully on the whole time. Mostly running at full 1000Mhz and with wifi on and downloading data every 5 or so minutes.
If I let it run down to 20%, I would probably get about 8 hours which is within the specs of the Archos 101.
I was pushing the device harder than average and I believe in normal use I could get more than 10 hours.
So I conclude the battery problems aren't related to the latest firmware release 2.1.04.
Yeah, looks like you might just have a problem with your device. Have you tried reformatting and reinstall?
After about 4 hours of usage (mostly Wordfeud) with Softlocker active (keeps device awake when screen is off) I still have 82%.

Saying that your battery is depleting at 1% per minute is useless information given that many electronic devices can sometimes drop by 20% in 1 second
Please only evalute battery usage by observing how much time it takes to fully discharge.
Please check battery history with the android system tool and also more detailed info accesible with this widget: http://www.appbrain.com/app/quick-battery/com.bwx.qs.battery

Yesterday I updated to 2.1.4 and really have not noticed any battery drainage. No issue from my side.
Updating last night on Archos 70 8GB, after fully charged all night and playing net for 20 minutes continuously, battery drops to 99%. No sign of drainage too.
don't see any issue on battery drainage on my Archos 70IT either =)
It is interesting, but in this thread I appear to be the odd freak out and no one is having any issue except me...yet in the other 2.1.4 thread, a lot of people are experiencing this battery problem...not sure why that is, but the problem is there and it is real even if it is hit or miss on people experiencing it.
Yep, it's real. I put in a service ticket. I wiped and reloaded my a70 today, but it was still drawing over 800 ma listening to Pandora. I only had about 30% left on the battery, and I wanted to completely discharge it. It's stone dead and on the charge right now. I'll find out early if it helped. 3am start tomorrow. Goodnight.
(first post ) I just installed firmware 2.1.4 yesterday, and haven't noticed any difference in battery life. Although, I have noticed that 3d games obliterate my battery life now, where they just ate it before.
Wiped, reloaded, completely discharged, and charged over night. Down 20% the first hour.

Mine is still around 10% drop every hour I have wifi on for net surfing. Mine just upgraded from 2.1.2, just for information.
don't see any issue on battery drainage on my Archos 101 IT either
One thing I am noticing is that is seems more sensitive to cranking up the processor to somewhere between 600Mhz and 1Ghz at various times. Before it wasn't as sensitive and often would stay in the 300-600 range for me. This change may be why people have noticed "increased performance/less lag?"
That might be part of the drain issue or something else.
I think the point is that it is hit or miss out there. Some people get the glitch and some don't. Regardless, Archos needs to address the problem.
Ok, now this is interesting. Just to try something different, I reformatted my tablet this time and installed 2.1.3, then restored everything with Titanium. I seemed to be holding up much better. After an hour it had barely dropped. To put it to the test I drove home from work with bt gps and google maps via tether. All tolled, in 2 hours it dropped about 10%. I thought I had it fixed. Then I realized I hadn't rebooted after restoring with Titanium, so it was still rooted. I rebooted it and the wheels came off. It dropped over 10% in about 20 minutes. I ran the root app again and it leveled right off. It's down to 10% now so I have to charge it before I can experiment more, but maybe someone else can try and see if they see the same thing.
Maybe root has something to do with it.. I've never rooted and don't have a problem.. I wonder if the only people having problems are the ones that rooted.. although it sounds backwards in your case.

I was wondering the same thing. It also seems to have to do with wifi, because with it off it draws almost nothing. The exploit has something to do with the wifi, so who knows.
Every night, my battery is drained by 7-8% even though, GPS, WiFi, all radios are off and the phone is in airplane mode (done automatically via LLama scripts). I installed GSam Battery Monitor to try to figure out what was going on and it indicated that even though the screen was dark, it was draining the battery (and was the primary culprit). Is this accurate or is it a bug? Anyone else seeing something like this on their Nexus 4?
Mine shows 78% usage in dark.. I think that just means how much of battery total it was used while the phone screen was off. I'm taking a completely random guess here though.

So you reset the app right before going to bed and checked it first thing in the morning and in the 7 hours you slept, the main battery drain came from the screen?
I use the same app and I never noticed anything wrong. Still, battery readings are not always accurate... sometimes when I recharge my phone, it stays 100%for a few hours, then it drops 7-10% in a matter of an hour...and that's completely normal I say you shouldn't worry about it too much as long as you get satisfying usage times..

I'm not happy w/battery life and trying to track down what the culprit is. If all major services are off at night, 7-8% battery drain doesn't seem normal to me. Granted this is apples and oranges, but my iPad Gen 3 in the same configuration remains at 100% overnight.
If doing nothing drains nearly 10% over 6-7 hours, no surprise I've got issues during the day.
I've noticed the same thing, one time I didnt turn the screen on on my phone, then I went to screen and it showed 0% discharge while screen on, and 7% discharge while off. I'm running the latest version of Viper, I'm also confused and I wonder if theres some issue where maybe power is being sent to the screen even though it's not on.

After my 7 hours sleep.. Every morning my phone uses 2% battery drainage at MAX. i.e.: Wifi Edge Sync etc ALL OFF. And I am getting 4+ screen time on my phone with moderate usage. Pretty happy with the battery life so far.

Your phone probably isn't going into sleep. The Nexus 4 seems to be prone to insomnia caused by apps that don't cause a problem on other devices.
To check this download CPU Spy from the play store. Run it, reset timers to zero, and with the phone on battery (i.e. not on charge) let it rest for 30 minutes or so, then check the figures.
You should see Deep Sleep as > 90%, if not, or it is listed as an unused state, your phone isn't sleeping.
To fix this you either work forward or backwards!
Work forward:
Factory reset, install CPU Spy, run the test and see your phone is now deep sleeping.
Start installing applications one by one and after each install, run the app, then run the CPU Spy test again.
Eventually you will find the app causing the problem, all you can do is avoid that app. Note you may have more than one app causing a problem so keep checking after each install.
Work backwards:
Start by un-installing an app at a time restarting your phone in between then running a CPU Spy test. Start with any live wallpapers (even if not set to be used) you have installed, then any weather widgets. Note just un-installing is not enough, you must restart after each one.
Eventually your phone will start deep sleeping again so finding the problem app.
Hope that helps.
Regards
Phil
I tried your advice, and my phone is going into deep sleep around 90% of the time, so I don't think that it's a rogue app. I keep my phone on the dimmest setting at all times, and I only get 2.5 hours of screen on time. I have an anker battery.

Hello everybody, i bought my Nexus 4 2 days ago. Well, it comes with android 4.2.2, then i updated to android 4.3
But i have a problem, the screen leaves 43%-50% of the battery.
The minimum is 43% of screen battery usage. And the bright is at the middle, its not the maximum.
Can someone help me? If i use 3g/wifi or play a game the battery finish in just 12 hours...
Just wifi + standby sometimes 15 hours..
Thanks to all.
That's fairly normal. Screen will be the highest unless you make a lot of voice calls or listen to a lot of music.
No, its not normal.. I was charging my phone and now i removed the charger (full charged) and the screen was with 81% battery usage but after 2 minutes it down to 51%-55% at the time im writing this answer its 55%
In 10 minutes just with wifi on is 96% now.
Thats so bad.
My advice
Rooted Stock.
hmm its 62%, well, i think its not normal, well lets wait google make a new update..
Now i restarted my phone and the screen battery usage is 7% lol.. this is crazy.

Just disable the: Settings > Location Access > Wi-Fi & Mobile Network Location.
Disabled now. Lets see how it will work.

Remember that disabling that setting means you practically have zero location services working. you're relying on GPS only, so apps like Google Now, weather widgets, etc. will not work.
The analogy I like to use is to solve a leaking pipe issue by shutting off the water main. Sure the leak is stopped, but you're not going to be able to shower or wash your hands. So in the end your water bill is $0 not because you stopped the leak, but because you also stopped doing other things.
I don't doubt you'll stop the battery drain, but we never really fixed the leak. I guess only Google can do that.
Edit: What I also noticed is that if you've already booted up and you disable the location services via Mobile Data/Wifi, then you end up getting 100% wakelocks. I can upload the screenshots after I get off work, but I tried several times resetting CPU Spy and BBS stats and it was 100% wake.
Once again in the water main example, if you turn off the water main while you shower, the water left in your pipes will continue to flow. It's not the same as turning off your shower which cuts off that water to you immediately. What probably happens is you're revoking location services permissions by unchecking the box, but apps like Google Now, Weather Widgets, etc. will continue trying to request for location. Since you've given the apps permission to use location services, it will try, but since there are no location services GPS, it will just continue to wakelock.
A reboot does solve it where I think the app will stop requesting for location services.
I think The main problem is not the location settings
I disabled it and my battery its like enabled.
It drain 5%-10% in 30 minutes or less with just WiFi on.
This is really bad..
I don't think you quite understand what it's displaying.
The battery history shows the percentage used of the battery consumed. So if your battery level states 75% and the screen states 60%, that means out of the power consumed your screen used 60% of it.
In a typical day the bigger percentage your screen uses the better. That means you aren't suffering from wake locks or other battery draining activities.

Yes, but i think the battery is going a little faster than normal.
If im mistaken sorry.
Solved nexus 4 android 4.3 battery drain
:good: You have to disable in Google Now > Settings > Voice > Hotword detection.
This feature turn on the mic all time and try recognize your voice to do a action.
Just disable that, and the battery will take a good life duration
I made this.
But im having yet the battery drain. I wake up and i take off the charge, it was 100% after 15 minutes with wifi and facebook, whatsapp on the battery drain 5% (95%)
After 7 hours (now) with much use (playing modern combat 4 15 minutes, real boxing 5 mins, dead trigger 5 mins) with 3g always on, the battery is now 41% (now i turned off 3g) is this normal??
Or my battery is really going faster than normal?
Edit: I started to play real boxing for 10 minutes again, the battery was 40% after playing 30%. Wifi and 3g off.
How exactly do you update it to 4.3? Mine's still on 4.2 and I check Software Update in the phone and theres no upate.
Well it was on the software update..
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.
