Battery life's non to fancy

I thought with a battery this big there wouldn't be much of an issue but if you push this phone it won't last the day.
I have screen set to auto, manual sync, data off, wifi off, gps off and here's how I got on today.
6am Of charger and 5mins checking email twitter then wifi off
7 hrs radio and music player,
Then through out the course of the evening I checked emails etc again for a max of 15 mins.
Phone turned of at 8pm so thats 14hrs but that was 14hrs with everything turned off and not really using the phone, my Desire S I used the same way and at this stage of the evening it still had well over a 3rd of battery left almost half. I installed Juice Defender yesterday and it made no difference.
Is this type of battery life normal for this phone?

A lot of battery related threads are there pal,

Just keep in mind that if you are getting around 5/5½ hours screen on time then you are fine, just fine. Forget about days. And JD will do no good if it doesn't do any bad.
Regards.

Keep in mind I am using Ninphetamine 2.0.2 kernel with villain rom 2.4.2, juicedefender, and did a proper, full battery calibration.
Today I played about 2h of games, listened to music for about 3h, and then did random things like checking email, downloading apps from market etc. I have only Wifi and autorotation always enabled. It's been about 12 hours since I unplugged it, and I am at 83% of my battery life. Looks like I won't have to charge it for 4-5 days using it regularly.

That's about as good as I've managed, but that's with it basically being still, only sending a few text messages. Don't think it'd have managed that long with music/game playing added in.

If he had mobile data and the phone turned off and just on wifi that's doable.
Listening to music with the screen off is a pretty low consumption scenario, cos the cpu will hit 200mhz and the dps' will be doing most of the work.
And considering that the screen and the mobile data connection are #1 and #2 users of power!
Doable but still maybe a slight exaggeration.
The phone has a very low idle draw though, so when its just sitting there not doing anything in deep sleep, you know you wont find your battery dead which is good.

Do people really not have access to chargers in a 12-24hr period? I don't get this whole batt life issue. Yeah,they suck, but seriously, who can't plug their phone in for 20-30mins a couple times a day?
oh and I deft call BS on not having to charge for four days. Never going to happen. Even if you dont touch your phone at all for four days. Still won't happen.

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

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?

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.

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...

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.

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.

Weird Battery Behavior. Any solution? Or time for an RMA?

I have had this phone for about 2 months now and everything has been exceptional with the phone. Have seen people complain about the battery life, however it has been really good as far as my experience is concerned. However since a week I have seen the battery screwing up a lot... A LOT.
I always used to charge my phone daily in night. Plug it in..set an alarm of 3.5 hours (yes it takes 3.5 hours to fully charge from less than 10% stage) wake up..turn charging off..sleep back. Okay, some of u might think it is stupid but can’t risk of leaving it on charge the whole night and burn my phone. Anyhow, so, since a week what I do is I charge my phone whenever I want (read it on a few thread and articles)..be it 50%... 80% or even 92%. I just make sure its 100% whenever I leave home.
But something weird has started happening... The battery percentage keeps on changing.. For instance:
when I unplug it..its 100%.. within minutes of usage it drops to 99..then 98.. then 97 and suddenly it rises back to 100%. (Pics attached)
Sometimes when its on charge and I come to check SMSz and reply them.. battery % suddenly drops.. e.g: if its at 99%... it will suddenly change to 96% in a second and in a minute goes back to 99% .. so on and so forth. And sometimes even when its charging..if it is at 80%, it will suddenly shoot up to 100%. The percentage doesn’t change even after a reboot. Weird, isn’t it?
Now the most weird issue, since yesterday the battery life and dropped to 50% less. I used to get 4 hours OST and now I hardly get 2 hours. During night, the battery used to drop 2% in about 6 to 7 hours and yesterday it dropped 15%. There was this one time when it dropped 9% in 6.5 hours (pics attached). Tried seeing through Wale Lock Detector but there were no Awakes during deep sleep. Too weird :s
I don’t really know where did I phuck up as I haven’t installed any shaddy apps or something. Please advice.
My phone info:
All stock. No root (and not looking). No custom Roms whatsoever.
TL;DR... Battery acts weirdly. Shows inconsistent percentages. Suddenly shoots up. Suddenly Drops. And now the On Screen Time has reduced 50%.

It sounds like it's nothing more than a bug.

This is "normal" for the N4, and the most/all of them do it. Unreliable drivers, or a hardware fault, not sure.

Anyhow, this normal behavior has reduced my battery life a lot.. which I am not liking .. What to do?

Both my N4's (different H/W revisions) have been doing the 100 to 98 to 100 thing as well since new. Battery life is still excellent for me. An RMA would probably do the same.

Happens with my nexus 4 too. But this hasn't reduced my battery life at all...

You're pretty much stuck with that phone as you only have 15 days to RMA a device, your only option would be to send it into LG for a repair. My battery has acted up like this once so I stopped using the stock charger and it hasn't happened since.

Ok. Thanks for replies. Do u think Factory reset would do "anything"? better?

Rebooting might help. Could also be an app that updated that now doesn't play nice. You could try a factory reset just to clear out some crap but I'd back everything up just in case first. Not sure if a factory reset deletes all your user data in memory or not. I only did it once right after I got the phone so can't remember. Hate to lose all your pictures, files, etc. that aren't backed up.

According to that you should contact Google if you got it from the Play Store

Thank guys for your responses.
Kzoodroid, i regularly back up all my personal data.. Pictures.. Videos.. Music.. So thats not an issue. And all the games and apps r also backed up on my hard drive. So i guess factory reset wouldn't harm much in my case. Any idea how to factory reset N4?

Yeah, just go to settings, backup & reset and click factory reset.
By the way, I notice you use battery guru and I was wondering if that application really helps in saving/boosting battery life. Personally I like "Greenify". It's a great app.

It's normal. The N4 isn't great about showing the exact battery life. In fact, what you see isn't the true percentage, it's an estimation. Don't worry too much about it!

This is a question I can't answer along with any facts. I tried disabling it for 2 days and I noticed the OST reduced from 4 hours to 3.xx hours. May its placebo or something but then I enabled it...thinking if it's not doing any good then it's not doing any harm either.

Hmmm, I didn't know that. But why is that? Any apps or something to show the exact battery percentage left?

Happens to me once in awhile. Do a quick reboot, and if that fixes it, I would not worry too much.

Hmmm..
Yesterday when I woke up in morning.. the battery lost 2% only in 6 hours. I felt SOOOO relieved that my "good battery" is back. But who knew what was to come... today I woke up after 7 hours and the battery lost 15% .
My usage is always the same. I force close all the apps I use daily and turn wifi etc all off. So i doubt if its any app.

Very Strange Battery Stats - Help Appreciated

I've just flashed PA latest build (dirty) and my battery stats are pretty messed up, apparently Bluetooth was the biggest drain on my phone, 57%, and it was on for nearly 50 days.
I don't use Bluetooth and obviously a battery lasting 50 days is nonsense.
I've had a search and found people experiencing high drain from some services, or reporting 100% charge as soon as plugged in, but can't find anything resembling my problem.
Is there a way of resetting these stats without having to do a full wipe. I tried charging to 100% but they remain.

get battery calibration app, should delete the stats shouldnt it?

Waste of time. Just charge your phone to full and battery stats are wiped.

Thanks for replies. I did a charge last night but the stats remain. I probably didn't charge to 100% just almost 100%.
I find that it can take up to 30 minutes to go from 99% to 100%. I will leave it charging overnight and hopefully that will sort it
That Bluetooth figure just seems weird, and I have no idea where it came from??

I can't help myself........ Need attention
Seriously though it's a bit strange that we both got that, could these be the stats of the ROM builder and they got left in somehow?? I know the 15th June version wasn't official and just put out for feedback. Apart from the battery thing it's awesome

Probably, but I guess its just derp. Anyways running Franco kernel and PA on this and get 5.5 hrs of sot with YouTube and music playing all the time xda browsing Facebook and mostly on WiFi but on 3g when WiFi signal is lost when I go outside. Auto brightness on and screen does take up juice outside but I believe I could get 7 or 6 hrs if I played with settings, underclocked, minimum brightness etc...
