Nexus 7 dies when left idle - Nexus 7 (2013) Q&A

Anyone having this issue?
I leave the tablet when I go to work. When I get home it is non responsive. I have to hold the power button for 10 seconds to reboot it.
Is this a setting that can be turned off?

Do you have Netflix installed on it?
There was a thread on reddit which said that this is happening because the Netflix app locks the CPU when in sleep mode. But at the same time I haven't seen this issue on my tablet. The OP on the reddit thread did mention he was testing it with chromecast though.
Current solution was to uninstall Netflix. Worth a shot.

Mine did that yesterday. After I got it charged up enough to power up I found that the calendar app had locked up my CPU and drained ~60% of my battery according to the battery stats in settings.

Thanks guys.
My battery does not drain. It just becomes unresponsive.
I do have Netflix installed. I will see if uninstalling fixes the issue.

Mine did the same thing last night, went to bed in the morning it wouldn't wake up had to reboot
set it down for about 30 minutes did the same thing, there was a system update available, i installed it and it has been fine all day
i did not have any battery drain and netflix is not installed

Had a brain fart... Netflix was never installed. I already installed system update (4.3 upgrade)

Samething happened here. Left it idle overnight and the battery died. Is this a software issue?

I flashed cleanrom, and issue repeated.

I haven't noticed any battery drain or locking while idle before I rooted and after I installed PA. I have to say though, the battery life on these are incredible. Forgot to charge it last night and it's still around 90-95% battery.
Anyway, I have to agree with the others, there's probably a wakelock going on. Check your battery statistics to see what's causing your wakelock.

Install gsam battery monitor, formerly known as bad ass battery monitor to see what app drains battery if your having battery drains etc. to check battery stats in native 4.3 click the battery symbol in the status bar and then browse battery or select setting / battery / etc.

Decided to get it exchanged to be safe. It does not look like a common issue.

I've got a similar problem. Recently (since the latest update), my device will be unresponsive to touch when I wake it up. It has only happened a handful of times, but enough to be a problem. The screen will rotate, and it will respond to side button inputs, but no touch. Every time has been after a prolonged sleep, and the only fix is to restart the device. My device is on the charger, so the battery is full. I do have Netflix installed, but have had since day 1 (actually day -2 since they released it early) and never had the issue before this last update. It's not something I can reproduce, but it's happened about 5 times over the last few weeks

i having the same issue as well and weirdly this only occurs after i put on moko casing
it was working fine from the first day until i got my new moko case, it went to shut down when i left it idle for few hours or overnight. It happened twice now so i will see if it happens again without the casing

my nexus is naked and completely stock

Mine is now doing this, Its happening all the time. Anyone know if this is software or hardware related?

I got the same issue too. I'm hopeful this is software related. I've been reading about similar issues in xda and google product support forums as well.

I had the same issue on day one right after my purchase...
Drained it to about 5%, charged it whilst the unit was on when I left for work the next morning. Got back from work and it was completely dead. Took it back for an immediate exchange.
System update was installed right after the initial bootup so I think it was a dodgy batch.
New one has been running great but I noticed that the 3d graphics were especially bad before it died so I don't know it the GPU had died on me?
Hopefully its not a common fault!

Same, but it wasn't charging. I was sitting reading Game of Thrones and I couldn't turn pages. Then I tried to lock and unlock it, change volume, rotate it, everything worked except touch. Only happened once so far but I'm blaming Asus' awesome quality control on their touchscreens.

edit: nevermind

Battery draining way to fast

I let my phone completely die last night because I wanted to get a full charge on this thing. I wake up this morning, and after 4 minutes, it had gone down 4%. It has now been 7, and it's down 7%. Anything I can do?
PS, it is now down to 90%.
Running Calk's rooted FC15 with ics4ics theme and the lockscreen mod.
88% now.

Been on it since Sunday. Location services are not enabled. Yesterday I noticed it had gone down faster than before, battery only lasted just over 8 hours with minimal use, but the wifi kept disconnecting, as did the 3g when wifi was off (this didn't happen in gingerbread).
I wonder if I don't need a new battery. I have noticed battery performance getting worse and worse over the past couple weeks.

I would take your battery and have it checked at Sprint. They will replace it for free if it's bad. My battery gets better after a day or two. I lose 2-3% while asleep on wifi and regularly get 4-6 hours of screen on time depending on how I use my phone. Did you check your wifi sleep policy?

Check what accounts you have setup, and if anything is syncing.
Goggle+, dropbox, and other applications have auto picture sync options which will KILL your battery.
Also location services in google or westher applications, and as always poor signal or no signal.

Yeah, I forgot to mention the sync options. That taxes the battery big time
Sent from my Nexus S 4G using xda premium
Sync is always turned off.
Well, I tried something: pulling the battery for a minute, then when back in, plugging it into the charger. I would give me a false full battery light, because when I unplugged, it showed 90%, and it kept doing this every percentage point, so I kept unplugging and plugging until it showed 100%. Well, 10 minutes have past, and it hasn't budged. So I'm chalking this up to false battery stats.
Thanks for your suggestions!

Yeah, I was going to mention wiping the battery stats but I figured someone would say that does nothing. I always do it when I set up a new ROM even though some do it on install
Sent from my Nexus S 4G using xda premium
How many apps do you have installed? Could be a rogue app in backround eating your battery up.
Also with wifi/3g constantly disconnecting also taxes that battery juice faster then a constant steady signal.
Sent from my SPH-D710 using xda premium
FYI, I am having this same problem on the same ROM for the last couple days. I thought I had isolated it to a problem with having USB debugging running when charging from the computer but that's not it either. Last couple days battery is draining so fast that I lose charge while plugged in! Have to charge from wall plug to get an increase in battery. I am having Android OS AND Android System at the top of my battery stats eating 35% and 34% respectively. Clealry not due to syncing or email checks or anything similar as this is the exact same setup I have been running for months (other than the upgrade to Calk's ICS ROM). I'm baffled....
Install these 3 apps:
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
This app will tell you what is holding wake locks on your device. Anything over 30 minutes over the course of a day would be problematic imo. But it depends on what you have installed.
https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy
This will tell you how much time your processor spends at each clock speed. Deep Sleep should be close to 80% with moderate use.
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
This will show you your percent per hour usage of battery. It's optional, but it helps me debug battery use. Typically I run 3-6% per hour with moderate usage.

So it figures, downloaded those apps, rebooted the phone and now its not happening anymore. This has been the problem the last couple days, its intermittent so I keep thinking I've figured out what's wrong and then it happens again. I'm thinking about going back to Gingerbread or trying one of the AOSP roms to see if the problem persists...
I noticed FC15 has the worst battery of all the leaks so far. It a joke shouldn't have even been sent to sprint for testing.

Gonna have to disagree with you there, maybe you have a bad flash. I'm getting an average of 16 hours with fairly heavy usage. FC15 has been fantastic, no issues whatsoever.
Im having kinda the same problem. I just had to get my rooted phone replaced yesterday not that it matters it was rooted I had no roms or nothing on it just rooted at the time, but my battery was fine. I got a white one I havent rooted or nothing yet and battery is going fast. I kept the battery from the previous phone. I was looking through appbrain and seen the app "bad ass battery monitor" and my kernal is killing my battery as of today.
Argghhh Bricked it!
Tried going back to Gingerbread and hard bricked the phone! 5 years on android and four different phones and this is the first time I really truly bricked. Blue led on and not a thing else.
Well I guess getting a new phone is one way to get back to Gingerbread.... For now, I'm sporting a cutting edge Blackberry tour!
Why is this phone so easy to brick? I've had 4 other Android phones and I see more bricked posts for the e4gt than all the others combined...

Before the ICS leaks, this phone was virtually unbrickable. Once we get the ICS source and the recovery issues are sorted out it will be that way again. If you stay clear of wiping individual partitions and follow directions in OP you are safe

Mine has been horrible and have no idea why. I haven't changed apps or anything from previous installs or settings but Android OS loves to eat 50% of my battery which is a good 25% higher than normal.

battery drain issues

OK, I noticed my battery has only been lasting half a day lately. Checked and discovered Facebook app to be the culprit. Uninstalled it, recharged my phone and went to bed. This morning my battery was down from 100% to 30%! Android system the culprit this time. Any ideas what's going on?
If you had BusyBox installed, try a hot restart, solves the wakelock problems for me.
Apart from what you wrote there, there is really not much info to work on.

It means some app is excessively waking up your device (eg. polling for something). Unfortunately, the Android battery stats won't flag it, which is a shame.
Install Better Battery Stats and find out which app is causing the wakes. Alas, there are many badly written apps written by clueless developers. Facebook being a good example, but you already found it.
Do you have a lot of apps that are free because the developer used ads? If so, those apps could be running in the background and seeking a network connection for those ads.

Facebook app is terrible, I think it got worse in the last update. Yesterday I started with a freshly charged phone on the extened batt and from 8am to 3pm I am down to 30% power. Uninstalled it and I used the rest of the power to 1am, recharged the phone overnight and 8am to 3pm, I am still sitting at 76%....
Agree with most. Heres my solution. Aokp build "whatever is the latest" with francos stable or nightly kernel. Juice defender app does well however aokp kind of has it built in under rom control / power saver. My stock nexus would get like 5 hrs now with current setup i see a little over a day depending on how much i use the phone that day

Normal battery drain?

Hey...android noob here. Got my first Android phone a couple of days ago after being an apple fanboy since the first iphone. Loving the note 2 so far. I have a question in regards to battery drain...unplugged last night after full charge and went to bed..woke this morning with about 82% left..it was idle the whole time except for checking the time a couple of times throughout the night. Does that seem to be on par for the typical battery drain? Thanks in advance. Loving the forums here so far.

You can conserve you battery by stopping some of your apps
Eg : if you have youtube running this will help run your battery flat quicker
I turn off any apps that i'm not using even data ,gps ,location services etc....this can effect some widgets tho
Hope this helps
Ps some phones and tablets won't let you shut down apps so they will run constantly

Hi Mate,
Download an App called CPU Spy.
Power off the Note 2(do not restart) and turn it on.
Leave it for a few hours and make sure if the phone goes to deep sleep when not in use.
When u r charging the phone the state would be 200MHz so if you remove the Changer without turning on the screen it does not go to deep sleep.
So always turn on the Screen before removing this.....
Hope this helps
Regards,
Pravish
Not normal I'm afraid. I think most I've lost during a night is 3%, with wifi and 3g turned off but not in airplane mode. Most days I wake up with the same exact percentage as when I went to bed, i.e 0% loss during 7 hours.
Removing the charge with the screen off won't kick it in to deep sleep? Interesting, but sounds like a flaw somewhere. Where did you find this information?

That's not true! I remove the charger without turning on the screen most of the times and my phone does get deep sleep.
Not to mention the screen is automatically turned on when you unplug.

[Q] Short battery life

I've had my Galaxy W for just over a year. Whilst I was running the stock ROM I would more or less get a full day out of the battery. I upgraded rooted my device and installed the Cyanogen CM9 rc2 ROM. I don't recall any battery problems at first, but just over a week ago it started draining within five or six hours. This happened every day for a week.
Since then I have uninstaleld all apps (apart from Google Authenticator which I couldn't manage without), turned off wifi, bluetooth and everything else I could think of. Now I seem to be getting about 36 hours out of the battery... Although I think it goes from 35% down to 10% very, very quickly.
Leaving all data connections off and having no apps is okay in the short term, but is there a long term software solution?

Before I uninstalled any apps I downloaded and installed CPU Spy. Here are two screenshots taken with CPU spy.
I could reinstall it now without any other apps installed, if that will help?
I don't know enough about this, but I expected that the phone would spend a higher percentage of it's time in 'deep sleep' than that.

Interesting.. how about you check on the battery is it bloating or not?
For battery problem is either the phone calibrated wrong readings on the battery or the battery it self is the problem.
If you use your phone not too often but the deep sleep only reach 34% of the time then some apps is preventing the deep sleep, try to check what apps is that causes that with some battery stats app, try search it in xda or market

I've gone for Battery Stats Plus. I'll reenable wifi, bluetooth and 3G for a few days and see what happens. If that takes a toll on the battery I will post back with details from Battery Stats Plus.
I will also take the battery out later to inspect it.
Update:
My battery had 15-20% remaining and I turned it off, and tried to turn it back on. It now thinks that it does not have enough power to boot the phone. I don't know if that new information is helpful or not.

With 15 - 20% it should have boot, because it still have juice left. What about your battery physics? Is it bloating or just normal?

Took the battery out this morning for a proper look. There's definitely some bloating. Time to get looking for a replacement battery?
Could there be two issues here? As from the screenshots I posted the phone doesn't seem to have spent a lot of time in deep sleep.
I was just watching a YouTube video, with about 70% battery. The phone turned off, and when I've turned it back on it's gone down to 2%.
Could this be down to an improperly calibrated battery, or is it purely down to the physical damage/bloating to the battery?

sorry I didnt see your first post (about bloating) :/ , definetely you should buy a new battery
Thanks for your advice.
I'm going to install Battery Calibration by Nema from Google Play. I'll see how I get on with that.
I'm going to order a replacement battery this week. I'm looking for a direct replacement, with an official Samsung battery. I have posted here in the Accessories forum. I hope that was the right place to put it.
After I install the CM10 alpha 6 conform to the first post, the battery life of my cellphone has been drained very fast - 21% about 6 hours and half.
Can anyone help me, please? I already did the battery calibration and I can't see effects. I'm wondering if is better install CM 9 or just go back to the android 2.3.6 factory version of my cellphone.

Your battery is bloated? Then you *must* replace it. Period.
A damaged battery is the root cause of myriads of problems. Until that battery is replaced, you _will_ experience all kinds of annoyances, no matter what ROM/Kernel you're using, including inexplicable battery drain.

Battery drain, of the crazy variety

So it has happened a couple times where the tablet says it has 28% or so and then my daughter uses it and in about 5 min the battery is dead. Has this ever happened to anyone, is it from being uncharged for a while and by that I mean I haven't charged it for about 3 days? Its not to big of a deal just weird.

Probably just a calibration issue. Charge it back to 100% and keep and eye on it to see if something similar happens again.

I've had that problem, particularly when using what I assume are labor-intensive apps (Skype, Candy Crush, The Room). It really bugs me, since the tablet ought to be able to handle these without significant drain. But I'll see my battery go from 40% to 5% in a matter of minutes.

I made this account just for this EXACT issue..... same thing has been happening to me, battery loses CHUNKS in the matter of seconds, its not a calibration issue, i have fully charged it many times.
i just got not even 5 hours of screen on time with my note.... freekin pathetic. its a fresh flash of clean rom too. battery drain like crazy... i think im gonna try to odin to stock and send it to samsung... i think this tab has a battery defect.
Ya it only happens for me when the battery is getting lower at around 40-35% then sometimes it just drops stupid fast. Also I'm not rooted it's a stock tab

I have the exact same thing. From about 30 - 35% it drops in a matter of minutes until empty.
Did anyone figure out yet what causes this? And is there a solution to it? I also sometimes have issues to power on the device. When pressing the power button it doesn't respond. I had this a few times now, after pressing the button for about 10-15 seconds it finally switches on... Anyone else had this issue too?
Yes im having the same problem. As im viewing this post, ive lost about 3% battery. Last time i buy a samsung tablet. They dont optimize or update to patch their mistakes. Horrible.

I had the exact same problem......
And the solution is.....
FORGET ABOUT IT... I know that it turns u crazy and makes u just watching the battery percentage waiting for it to drop....so annoying
But what I decided to do is just forgetting about it and use it normally and dont let the battery percentage go too low and by time and charging and draining the battery over a month or so it became perfect!! It even gets charged in less time (about 4 hrs)
agree
This has now happened to me twice. Id be hovering at 35% ish, and in 20 mins of video watching im down to 16%. Something is amiss
I never had this problem until i recently Rooted the device and installed Clean ROM. Im thinking i should go back to stock firmware with Root and see if this still occurs. Worrying
If people let the battrey drop to 5% then switch off the device. Then put it back on and then connect charger and charge to 100% in one go without using until it tells you to unplug....see if that works.
Obvs dont always do this....this is just to try to calibrate battery. Under normal conditions you shouldnt let the battery drop below 30% before charging anyway to protect the battery from severe degredation.

Had the same issue with mine, sent it to Samsung for what I thought was going to be a battery replacement. They just flashed a new firmware on it and that fixed it. They also put 2-3 scratches on my flawless screen. Idiots.
However, overall, battery life SUCKS on this tablet. It's way worse than the older 10.1 which I am using now because I can't get rid of Samsung's API locked sPen gestures on the 2014.

I get just over an hour per 10% drop, pretty happy with that tbh.

The problem might lie in the usage of a certain app... dolphin browser for example... enable flash on it and your tablet drops 10 percent a minute or more ... you should look if the tablet is draining also by doing nothing by just having the screen on.... there is also the possability of having a bad external sd card that causes android to loop media scanning nonstop....
Im rocking android for some time now on multiple devices... and it was always some rouge app which caused this ... causing wakelocks and stuff... you can look for whats draining battery with wakelock battery monitor... or better battery stats... try to keep android as clean as possible ... some apps just drain like hell.... even facebook ... because of background services
