Terrible battery life

Hello everyone, i purchased my Nexus 7 and it arrived in the mail 3 days ago. And as with every other Android device ive ever owned, the batter is absolutely terrible. I get about 2hrs on screen time when browing the web and maybe playing an occasional game. Does anyone have any idea whats going on? Or have any way to help? Thanks so much

That is pretty bad. Try a factory reset. Might be something you installed.

I'd hate to do a factory reset cause I just barely got it set up but..I'll try it anyway tonight

Doing a factory reset before installing anything is becoming the gold standard.
Hope it helps you.

I get between 7-9 hours of active use. Sounds like some process is running amok on yours. I didn't factory reset when I bought it either....though I have rooted it since then, but battery life is about the same pre and post root.
You might want to consider a program to monitor battery use to see what's eating it up. Maybe do that before you factory reset it so you don't install the same thing again.

Really? Like as soon as you set up the device, you are suppose to factory reset it? And since im facotry resetting it 3 days into having it, do i have to calibrate the battery again?

Do you have any battery monitoring apps in mind? I would love to see what is eating up my battery

System panel is a good app to find what's using your CPU and better batterystats can help find what's keeping your phone from going to deep sleep. An easy way to see if this is the case is go into battery setting and select the first option(history details). Compare the Awake bar with the screen on bar. Those two should be nearly identical if not then you have a rogue app.

The one I've seen mentioned several times in here is BetterBatteryStats. I just don't want to drop $3.00 on something I don't need. It might help your issue though.

have you flashed any kernels or roms? sometimes this makes the tablet report the wrong battery stats for a bit.
did you run the battery down until it turns off and then give it a full charge? sometimes you have more juice than what is being reported. ive been stuck at 1-2% for over an hour before. Most likely its a rogue app though, system panel and better batterystats should find out what app it is. if they dont then it could be that you have a defective battery...

Been on mine continuously for 3 hrs 18 mins and at 60%. Excellent if you ask me. Next step up in battery life would be Transformer series with dock.

Quite the opposite for me; unlike every other Android device I've had (Nexus One, GS2) the battery life is excellent. I watched 720p mkv video on the train yesterday for a good 3 hours, and still had ~70% by the time I got home, from a full charge.
The battery life is excellent, as far as I'm concerned.

Don't think you needed to calibrate the battery to begin with. I usually get fine battery life without doing anything special.

Something must be causing the poor battery on your Nexus, Yesterday after my N7 was fully charged, I watched the movie Thor for 1hr and 54 minutes n and my battery only dropped to 83%.

I'm at 16 hours and 52 minutes with 3 hours and 44 minutes of on screen time, the battery is at 51%

My N7 is completely stock and has never been rooted. I also did do a couple charge cycles which didn't seem to help much. And better batterystats has AudioOut_2 at 38% (while I'm playing music) but other than that it doesn't seem to be a rogue app

Unless you listen to music for over 5 hours or streaming the songs it shouldnt use that much battery. If you can't find a wakelock with better battery stats then it might just be a bad unit.

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.

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.

Thanks for ur reply. How to figure it out? And measures should be taken? Any suggestions?
this has really kept me worried since a few days.

This is "normal" for the N4, and the most/all of them do it. Unreliable drivers, or a hardware fault, not sure.
Here are other threads about the various battery bugs, but there are many more:

I know I searched many threads before posting and mostly had the Shooting up issue only, when charging.
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.

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.

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?

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.

[Q] Battery life is turrible

So, I got a Galaxy S4 back at the beginning of December, and the battery life has just been awful since I got it. I'm talking 5 hours max.. of juice. Its bugging me because I have tried so many different options and nothing makes it last any longer. One time I got 8 hours and I was like planning on throwing a parade because it was so groundbreaking for my GS4.
Here's what I normally have going on:
Admittedly I use my phone quite a bit and it's always on full brightness because hey its a $600 1080p phone so I want to be able to use it to its full potential.
I do not have one game installed. Never been a huge fan of mobile gaming.
I usually have a 4-5 bar 4G signal and barely use my wifi because it's like 300kb/s down.. And really spotty.
I may listen to 30 minutes of music a day.
Most of the time I'm on twitter and looking up stuff on Chrome.
This is not a battery issue I do not believe because my brother got the same phone and he has had similar issues. My brother uses his phone maybe half the time I do, so I doubt it is my usage that is bringing it down. I seriously do not want to have to contact Samsung for them to tell me it probably has water damage and then ask me to wait 2 weeks to get my phone back. My phone does tend to get warm from time to time but I've seen multiple reports of that. My iPhone 4 that I upgraded got 8 or 9 hours of battery life on similar use. (Android rocks)
So what is the problem?
P. S. my phone ran down 8% while typing this.

Are you running a custom or stock rom? And are you rooted?

Look at your battery usage in settings. Screen should be number 1. What's after that? Get betterbatterystats and see where your wake locks are. Without some additional info it's hard to help you

It depends on what I am using the most. Most of the time its below 10% of total battery use. I would say it is mostly Chrome at 4-8%.
Right now it has been on for 37 minutes and is at 85% battery.
84% screen
7% Chrome

so under battery usage it's just screen and chrome usually ? (iId dump chrome to begin with anyway)
Is GPS on ? Any other apps that would be constantly syncing like facebook, twitter, etc ?

Yes, normally screen and chrome are the biggest consumers but I do use a few more apps. I've been wanting a Chrome alternative, but nothing I've tried has been as efficient.
I do use Twitter and Facebook(rarely), but at the same time, my brother doesn't use any social media and his battery isn't much better.

The biggest user of battery would be the screen, LTE, and GPS or location based processes. Honestly LTE that doesn't use much unless you are streaming all the time. Something isn't letting you phone go to sleep and if you can root I would just do it to be able to use an app like greenify or another wakelock killer that lets you keep apps from keeping you phone awake. Also turning off sync in general helps i.e making you refresh stuff manually.

Thanks for your help so by the way. I always have gps off and I only get regular 4G in my area. I will check with Facebook and try to turn off automatic syncing. Rooting is an option, last time I went through kingo and did it just fine until I tried to flash Cm over my locked bootloader *facepalm* Haha. I haven't heard anything definitive on the downside of using that tool. It was very simple. Would you suggest me going that route for Greenway?

No problem just hit the thank button
I'd root and just leave it stock the rest of the way. With battery life it's always YMMV. The battery stats given in the setting menu don't tell you much so apps like wakelock detector or Greenify allow you to stop apps from "waking" the device all the time to either push notifications, sysnc, do whatever crap they do in the background. You could also get something called better battery stats, the app in on xda just google it, and let it run from full charge to dead and then take some screenshots of partial wake locks, how often CPU is in deep sleep etc and others can help sort some out.
Just root with Kingo as its easy and leave the custom rom's alone haha.
BTW how did you fix the brick form flashing a custom rom on MK2 ? I'm on the good MDL firmware so not sure how others fixed the MK2 brick

Well after about a zillion tries on Google I finally found where someone got out of soft brick. It was something like hold down volume down, home, and power buttons until two options come up after you first power on the device. They are like "proceed to recovery mode" or "boot regularly" (something close to those anyways) and then you hit the volume down key to select boot regular and it boots up the phone without seeing that Oden screen. I was so relieved, I had already BSed my chat with a Samsung rep so they probably would have fixed it do to "accidental" downloads caused my phone to brick.

Watch out having your brightness to 100%. My statusbar got burnt into my phone. Just be careful. I can see the clock numbers(blurry) as well as battery and such. It sucks.

Yeah I just wish I would have been warned as well, now I just keep my status bar off. It's not directly noticeable if I don't look at it but it's still there.

My charge wont last even 2 hours screen on time.
Pls help me i tried to calibrate but it just made it worse.

You need to figure out what's drainng the battery. Get gsam or betterbatterystats to figure out what's causing it. Anything else is just a guess.

If you don't see anything unusual after a few hours of using GSAM/BBS, no extreme wake locks or times held awake, I would then do a factory reset and see if the problem continues, if it does then you may have a bad battery and it will need to be replaced, it is not difficult to do, a simple YouTube search will show you tons of examples of how to do it.
If that isn't it, although it is rare, you would have bad hardware and need to get the device serviced or replaced.

İ was using pa but i unrooted and stocked my devixe yeaterday but its the same.My other battery was way worse but this one is annoying too.Could it be the brand of the battery?

Download and install from the playstore the app Wakelock detector, let your N4 get to 100% in battery and unplug it and try to use it as usual. When it reaches 10 or 5% take a screenshot of wakelock detector and post it here. Try also to take a screenshot of GSAM or Betterbatterystats.

do you try to change kernel or rom ?

Kernels and roms make very little difference. It's how you use the device and the wake locks you get. Without something like gsam or bbs it's only a guess what's causing the issues.

maybe there is some kind of secret service that runs on the background and drains the battery ?????? well thats pretty weird.....

this, absolutely right. battery life depends on how you personally use your phone, how you set it up, what apps you have installed, and mostly on the quality of the phone/data connection that you have.

İ dont think its a software problem guys.My newest stats: http://i.hizliresim.com/rLNLAB.png
Any calibrating suggestions?

We need more detailed information than this to troubleshoot this... Without that information we can't really help. We need screen shots of Wake lock Detector, BBS, or GSAM. GSAM is the easiest to interpret, so shots of the main screen, app sucker set to time held awake, screen and radio would be needed to assist further, in English if possible.

As i told,everything looks fine.

Everything does not look fine...Two things that's bothering me looking at this is the GSAM shot, it is showing you drawing 1500+ma off the battery... Seems very excessive, I usually see 350-900ma at most (433ma at moment). And the 41% of usage by the screen in just over an hour use seems kinda high, what is your screen brightness set at, and what does the GSAM Screen usage screen say, anything in the Medium or higher category is using very significant battery.

"Calibrate" is a misnomer, it will not affect battery life or current draw, years ago in the Froyo/Gingerbread days you would wipe the battery calibration file to reset the display and estimated run-time remaining, it doesn't affect actual battery use or life, just how it is displayed and runtimes are calculated. You can always download a Battery Calibration app from the Play Store and use it, it won't hurt anything but I believe most require root access. I have seen some discussion that this is irrelevant in KitKat since the file is rebuilt on each boot, but I can't verify that.
Honestly though, when I look at your GSAM screen with 2:40 average screen time and just over 3 hours max, this part doesn't look unusual, but it doesn't jive with the screen shot showing 1:19 screen time using 42% of the battery... you are at 12% after 10.5 hours, the phone is obviously sleeping properly (only 28min held awake over 10+ hours is quite good), but at the same time you are showing 5%+ per hour drain. A little puzzling but not outside of the realm of normal.
I'm not really sure what else to say, every phone is different, this may be normal for your device, without screen shots of app sucker and screen usage in GSAM I can't really say anymore... try the standard stuff like switch to Device Only in location services to stop Google Play Services drain, lock the screen brightness at 20-30%, disable syncs, etc.
Of course, this could be something in hardware too... I had a Samsung once that no matter what would drain 5-10% per hour well sleeping even in airplane mode, yet no one else in the forums ever commented that theirs did, turned out it was just a lemon, a replacement would drain less than 1% per hour.
