Ridiculous battery drain on standby

It seems that the battery drain on my newest N7 (RMA'd first one) is waay worse than on the other, I'll attach some screen shots of what I mean.. it may be just the WiFi is using a lot more than the other's :S I left it 4 hours alone with WiFi and the battery drained 20+ % which even with WiFi on seems excessive does it not? Is it possible I got one with a faulty WiFi radio? I will be testing tomorrow (or maybe tonight) to see battery drain with WiFi turned off to compare, because it also seemed to drain fast when I was just out and about with WiFi off :/ worried I have bad battery, deep sleep isn't working right (it is going into deep sleep or at least thinks it is from looking at cpuspy), or faulty WiFi... or just too early to judge XD has anyone noticed battery improve over time ? I forget if I did was a month ago I got the original
BTW first screen shot was taken pretty much right as I was leaving for work, so you can compare the battery drain there..

I doubt it's a bad wifi radio, its probably an app that is syncing like crazy in the background.

I'm currently watching the MediaServer app use a disproportionate amount of battery (14% and rising). I deleted a number of images which must of kicked in the scanner which must be very inefficient.
I also noticed my N7 become very slow at the same time.
Possibly you downloaded a large amount of images/music/etc before putting your device to sleep...

I really wish I could figure out why maps keeps starting a process.. can you check to see how many instances of maps there are ? In particular one running Prefetcherservice.. as for the other comment, media server is sitting at 6%, android is at 14%, and screen at 67%.. though I did copy a bunch of songs and pictures over after the RMA, is there a way to fix these or should I delete them to see if it gets better ?

Sigh, I might just have a bad battery, or preferably poorly calibrated, since another hour of use, just browsing and such, and I'm down 20% more -_- hope I don't have to RMA again

As a side question.. how hot does your tablet get under normal use? Mine has been heating up quite a bit in the battery section i think with just average on browser use :/

Nothing you've mentioned sounds even the slightest bit out of the ordinary. I know a person who thinks they are always sick is a hypochondriac so is someone who always thinks there is something wrong with their computing device a hypo-com-driac?

Bahaha good one I dunno, the problem is that this is literally my fourth N7 since the other three allll suffered from major screen lifting, so maybe I am looking for something wrong just so i can make sure it's perfect... Though I do think the battery life is pretty weak, I think I may have figured SOMETHING out, the only difference between this and my original is that my original had a huge section of the map of my area downloaded, and since I did that maps hasn't started any additional processes.. so good sign ? maybe ? haha

Yeah this might be a good time to stop looking for trouble and just enjoy the tablet for a while. I drop mine on the charger in the morning and don't ever really think about the battery other than that. Whatever the battery stats say now they won't say in a week and they won't say after you flash to a different ROM. If you have wifi on apps will sync and the tablet will loose it's charge. I'm never far enough away from an outlet to make it much of a concern. So maybe just take a breather, install the Angry Birds and have some fun for a bit. Eventually we'll have ROM's and kernels that make this thing sip electricity but for now I get the few hours a day I need out of it on one charge so I'm set.

You think the battery life will get much better than what it is? My only other android experience is my HTC Desire Z which has a horrible battery as it is so it didn't improve much at all with custom roms
Speaking of improved life through ROMs and kernels, have you noticed any kernel providing particularly better battery life ? I'm on trinity right now, no voltage changing, but underclocked to 1.1 ghz from 1.3

Factory reset, see if the problem continues. That's the only way decide if it's a HW problem.
And my N7 uses effectively 0% battery in standby, it was off the charger yesterday for 6 hours and when I started playing around it was still at 99%. I turn off wifi on screen off, however.

Use http://forum.xda-developers.com/showthread.php?t=1179809 to find out what's waking up your phone, the apk is in the second post. Install, charge it up, unplug, leave for 4 hours idle then look at partial wakelocks and alarms.
I saved quite a bit of standby time by disabling location services and Facebook.

If your not using nfc that could save battery?

I used Better Battery Stats to figure out Google Maps was causing wakelocks. I cleared data in the maps app and now my 7 idles without much battery drain at all.

So it seems like partial wakelock is mostly audioout_2 which i assume comes from me playing a game with music amongst other things?
Alarms says com.google.android.googlequicksearchbox has 50 wakeups, and maps has 38 :S why does maps keep trying to kill me?! and what is the googlequicksearchbox doing waking the tablet up...

Wlan_Rx_wake seems to be the culprit of semi bad battery. Is there a way to prevent the tablet from waking up all the time? Maybe just unsync or turn off WiFi instead?

When my battery drain was bad I had something like 250+ wakeups from maps under the alarms section in only a few hours off the charger and Maps was showing up as the most common reason for partial wakelocks.
I think AudioOut_2 is normal - Im not sure what it does though. Im now at 8+ hours of standby with 99% battery. Under alarms im showing 138 Maps wakeups and 76 from google quick search box. My drain is all gone now though so i assume this is within normal range. The better battery stats thread and a few other threads on XDA have detailed descriptions of the different battery draining wakelocks and possible remedies. Not all wakelocks are bad though.

What are sns_async_ev_wakelock, sns_periodic_wakelock, and main?

These 3 wakelocks are always about even with each other at anywhere from 50% to 90% of the time "since last unplugged". Anyone know what these are, if they're normal, or how to get rid of them?

turn off latitude helps a lot
but they are Android 4.2 bug, i think Google will fix them

Probably normal if you were on the phone or doing lots of texting.

Hmm they're actually increasing almost the whole time the phone is idle with screen off though. Latitude is off as well. I'll try a clean ROM flash after factory reset and report back. Thanks guys.

Unfortunately these are still present (and high) after a full wipe and flash of the latest AOKP. Anyone else see these at the top of your wakelock list?

Not on MINCO

I am having this issue too, I believe it might be an AOKP problem:
http://forum.xda-developers.com/showthread.php?p=37451238#post37451238

Well, I searched for hours, and hours for this wakelock too, and I think I finally found what it is, basically this wakelock is caused by the signal processor going berserk and waking up your phone constantly, most of the time this is caused by something disturbing it, and in that you have to think about something that could change or capture a signal in really the root and not through the official Android ways, like Viper4Android, it changes the audio kernel, this could disturb it, or automatic call recorder, this one picks out the voice signal, and this applies to almost all the sensors and signal processors

n00b here, need help with battery issues

Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!

If your saying you left the screen on over night, meaning the phone never went into deep sleep.. If you slept for let's say 6 hours and the phones screen was on for that whole time it's normal that it went down to sixty percent battery.
Maybe I'm understanding your post wrong? Btw I cannot see the picture you posted.

Turn off mobile data and lower the screen brightness to 0 during the day. Also disable WiFi when you're sleeping. I also make sure all apps are closed using the app manager button on the far right.
Mine's been fine following this logic.

Oh sorry, I should meant sleeping overnight, whilst I slept cosily in my bed.

This is NOT the answer. His battery in the image has dropped 7%. If he hasn't used the screen much it is perfectly understandable that screen might not be a large percentage of that 7%. As he uses the phone more screen will use a larger percentage of his battery and Android OS will use less.
If he gets to the point where the screen is on for an hour or two and the percentages are still like this then yes there is a problem.

Actually No the "Screen" should not always be at the top of the stat list. If you use the phone more than it idles, then yes... but if you are like me, mine says "Phone Idle: 20%" (which is on top) and "Screen" is 4th on the list with 12% (Wi-Fi and Cell standby above it) [this is my personal phone, and I mostly use my work phone. hence the high Idle & standby]
I was having an issue with my phone running out of battery, with very little usage from it. I mean very little, I might make 2 calls from it each day, and respond to an email now and then. I found that an App was preventing my Screen from going into "Deep Sleep" or even "Sleeping" possibly. So I uninstalled all apps (well I only had like 4 additional apps installed), except for 2 that I need (Google Voice & Drive). Powered off the phone, charged it fully, then powered back on. Its been running on the same charge for 24+hrs now and reads 68% battery remaining.
So check the apps you have installed, some use background data, and might be causing problems...

And your phone is the definitive guide for what Android OS usage is? Maybe his phone woke up those services for a period of time longer than normal.
The answer of "lol looks wrong root and install kernel" is terrible advice when so little information is given.

See now it is much easier to see that you actually do have a problem and what it is. You have the wakelock problem as you can see from Better Battery Stats which falls under Android OS on the other screen. It also appears that you have somewhat weak signal which could cause the wakelock to drain battery even more. There's not much you can do about that wake lock, some kernels have patches for it but those have their own issues as well.

Could I just install any kernel on stock android and be OK with it? As I've said I've no idea what's best for me; just something nice and clean that doesn't have issues like this. I live onsite where I work so my WiFi is pretty much on all the time if that helps in anyway whatsoever
I'm gonna let it run down completely tonight and charge it, but I don't expect it to help much.

Fully charged overnight, battery still sinking like a ship. 45 minutes and I'm already down to 94% already!

The battery on the n4 seems horrible.
I'm completely stock I just got my phone yesterday, I charged it to 100% now its at 64% battery with only 47 minutes of screen on time.
on the s3 I would be around 83% with 47 minutes of screen on time.
I'm gonna unlock the boot loader and root soon and try Franco kernel I've been reading good things about it.
Sent from my Nexus 4 using xda app-developers app

The battery life on the stock kernel isn't great because the CPU management isn't optimized well. It ramps up the CPU (frequency, number of active cores...) very easily and keeps it there long, which removes the occasional lag but sucks more battery. Flashing a more battery friendly kernel would definitely help you if that is the root of your battery issues and not a badly coded app.
Franco's kernel is a very popular one, and very battery friendly compared to stock (and that doesn't mean you lose performance). It is the one I'm currently using. Most people report of screen on times of 4 or 5 hours. With not so heavy usage and wifi (not 3g) I can also pass 5 hrs.
To install a kernel you need to unlock your boot loader and install a custom recovery. No need to root, but.. why not since you're at it
You can try different kernels with the stock ROM. You don't necessarily need a custom ROM. Just be careful to read the dev's OP and instructions, and definitely not to flash a kernel for another device.
Also another thing that reduces battery is your mobile data, if there are a lot of programs that sync on the background. You can use a program that turns off your mobile data when your screen is off and switch it back on just for a sync every xx minutes. Juice Defender is such app, though I like to use Tasker for that. If you use Tasker and are interested in that project, ask or send me a pm. It works great.

[Q] msm_hsic_host causing battery drain?

Hi everyone,
I noticed some heavy battery drain during the night. So I installed BetterBatteryStats to find the culprit.
The phone was fully charged and uplugged before going to bed. 7,5 hours later there was 80% left.
In the log "kernel wakelock", "msm_hsic_host" was on for 99% of the time and in "other" it showed my phone was awake the whole time.
I couldn't find any related threads here, but some on the nexus 4 forums. It seems to be related to the radio searching for a good signal, am I wrong?
I'm on stock rom XXUAMDE, rooted. Wifi was on, mobile data off. I set network mode to GSM only. I noticed yesterday the signal bar in the battery log was yellow/grey most of the day with GSM/WCDMA (auto connect) and green with GSM only. It appears 3G signal isn't the best in the area.
Any thoughts on how to fix this or some tests I can do?

Here are my battery stats for last night. 3,1%/h seems a bit too much. This is with MDN firmware btw, but no change.

I did a factory reset. I could not find the problem, so I had to do something. While installing the apps I kept an eye on the battery consumption, but
everything seems normal. At night it lost 3% with wifi/data/nfc on!
Still no idea what was causing the battery drain though, but at least it is solved now.

Battery Life is absolutely horrible

Ive been using an iphone 5 and Optimus G Pro for the past 8 months waiting for the new androids to come out this fall and I am quite disappointed. I have the ATT version, i have wifi, gps, bluetooth all off, never had to do that on the iphone. I close out all the apps and clear the ram, and I went through 30% overnight while I was sleeping. My Optimus G Pro was far better on battery and that seems kinda backwards?
Is there like a break in period or something, what is the deal here

You have to figure out what application is causing the "wake lock"
What a wake lock is; Its something running in the background that is not letting the phone "sleep" or otherwise go idle. Meaning your phone is running full speed ahead while you are sleeping.
It could be all sorts of things causing a wake-lock. I had one guy on my ROM have a wakelock because his internet connection was so poor the phone just kept searching and he was draining about what you are draining everynight.
Another thing I would look at are your location settings, not just GPS. The new Google settings Icon has a bunch of crap that it syncs and tracks you via all sorts of stuff. Go in there and make sure nothing is turned on you dont need...
And lastly, like the other guy said, check for a battery stat app. They can show you what app is not sleeping or why your phone is not sleeping like it should.

Facebook is a notorious offender. With refresh off I would get over 140 wakelocks in a 7 hour period.

mine is way better now, after being off the charger for 3 hours I'm at 94% where as yesterday I was probably at like 70% at this point.

Don't forget most android handsets need a 72 hour battery calibration window before you will see a more even battery level. After 72 hours your phone should have a good batch of data to help gauge its power levels.

Battery is fantastic on this phone. Coming from an X and Note 2.

I'm still on my 2nd full charge but notice once the phone huta around 60% the percentage drop starts to slow down, I figure this is just calibration getting dialed in and so far I'm very happy with battery life.

fd toggle
Hi there, I am not sure if this is the reason but I used to have Fast dormancy toggle apk on my old lgog to prevent the phone from complete discharge even though I was not actively using the devicd. I installed the fd toggle here,too and I can honestly say that if I am charged 100 % at about midnight, I have the same 100 at about 6:30 when I get up. Of course, no data,no sync,no wifi and no active use of any kind during that time. I do not know if the app is the key but the result is pretty impressive. I have the korean version F320K.

I was using the Snapdragon Battery app on my DNA. Never sure if it did anything. Is it worth using on the G2 as well? Love the phone! Less gimmicky than the S4 and more interesting than the Maxx.

Another thing I would look at are your location settings, not just GPS. The new Google settings Icon has a bunch of crap that it syncs and tracks you via all sorts of stuff. Go in there and make sure nothing is turned on you dont need...
And lastly, like the other guy said, check for a battery stat app. They can show you what app is not sleeping or why your phone is not sleeping like it should.

Scross tell me you got a G2 lol

This is dumb. My G2 was at 100% battery for 3 hours! You either have a lemon or your cell reception is poor where you are. The battery life is not horrible.

Yeah, I'm with the rest. I'm coming from a MAXX HD (insane battery) and the battery optimization on the G2 is far superior (albeit smaller battery).

Bought the phone over 24 hours ago and I am still on the charge from the box. Its running great for me with LTE on.
