Random shutdowns?

Has anybody experienced random shutdowns on their N4? It's happened twice now for me in the last few days. I'll go to turn on the screen and find that the phone is completely shut down and needs powered back up, without me having shut the phone down.
One strange thing associated with this is that it completely wipes my battery stats.

Please provide more information.
Stock? Unlocked? Rooted? Custom rom? Custome kernel? Undervolted?

Sorry, stock rooted. Both times happened when there was plenty of juice left in the battery, this morning when it happened I was still at 95%.

Are you sure it's actually shutting down?
The reason I ask is that there's an issue where the screen won't wake up, but the phone is still functional (can still hear notifications and feel vibrations etc.). It looks like it's shut down, but it actually isn't.
If so then I believe it's a known issue, even on the stock (unrooted) rom. It happens to me every now and then, and as far as I know it needs a hard reboot to fix (hold down the power button for 10 seconds).
Don't know what you mean by wiping your battery stats? A reboot would do that anyway, wouldn't it?

There's a video on youtube showing how this phone just shuts down after running a benchmark for long enough (that was about 10 minutes at normal room temperature..)
Could it be that your phone was doing something in the background, and because of the overheating issues that it has, it just shut down to prevent damage?

I wasn't doing anything significant right before hand. The last things I did were: checked Facebook, modified a Tasker profile, and swiped away a couple apps from the recent apps screen. Phone was cool to the touch. I was in the basement with no cell coverage (wifi connected), then moved upstairs and next time I tried to turn on the screen the phone was powered off.

No it was shut down, had to hold down the power button for 2 seconds to boot it, felt the boot vibration and saw the boot animation. This happened after being off charger for about 2 hours, but upon booting the battery screen showed on battery for 1 minute. Usually when I reboot the "on battery" time is preserved.

Is there a fix for the screen not waking? I'm still on 4.2(stock and rooted), does 4.2.1 fix it? I can't seem to update to 4.2.1, if it does fix it. But that's another issue...

Ya know I'm starting to think it may be my belt holster that's somehow shutting down the phone. This is the first day of my new holster and now the phone has shut itself down 3 times, each time I've noticed it after pulling it from the holster.

I only had N$ for 3 days.
Yesterday when I was taking a picture, camera app was running, while I was putting kids together phone screen went black. Only way to bring it back was to hold power button and it went through full boot up cycle, so I would say it did shut down on me.
Stock, no root, updated to the 4.2.1. Battery was between 50 and 75% and it did not wipe it's stats.

Oh man that's gotta suck. Worst moment possible. Mine has shut down as well several times.

I find that my phone likes to randomly reboot when using bluetooth. May be a coincidence or not. At times the widget toggle for bluetooth stops working too, so there's something going on with bluetooth. My bluetooth problems documented here:

Does anybody know a sequence of button pushes that will shut down the device? I know holding power for 10 seconds causes a reset, but is there a combination of button pushes that initiates shutdown?

If you hold just power button it should bring a popup with Power Off option, which is a standard for most Android phones.

I have the same issue recently. I've used nexus 4 for 1 month, this issue just occurred recently. it shutdown without any notice. I've drop my phone once, cracking its glass back, but it doesn't seem to relate to that issue. I guess maybe this is some software problem.

Fully charged battery became empty during night when phone was off

Hey,
I have an HTC HD2 (obviously ), what I've charged to 100% last evening. I've switched it off (I'm absolutely sure I did) and when in the morning I've switched it on it indicated the battery was empty, it was 0%. Of course the phone switched off almost immediately.
I'm using Android 4.1.1 ParanoidAndroid 2.15 by Xlyo.
What do you think, what could cause this really huge battery drain while, the phone was switched off?!
Thanks in advance!
VDodi
EDIT: I've forgot to state I have had no battery issues before. Normal drain at all time, 4-6 mha during sleep.

Hello,
Was the phone/battery hot when it you touched it?
Could be as simple as a bent battery pin.
Good luck.

I did not notice anything unusual... besides it became empty
Anyway nothing extraordinary happened before or up until now, so... i do not know... perhaps just an error in the matrix

What do mean by switched it off?
If the display is off many things still can run, wifi., Bluetooth, , app update, a game...
If you mean physically off the hardware is cause as stated above.
What does 'current widget' say just after waking up?

Hey,
I mean the switched of as turned off (power off).
Btw. really interesting because I clearly remember the Android started up, but no logs have been made by the CurrentWidget I have a log entry from 0:01:16 and the next one is 22:37:29 (I charged the phone via recovery and only after went to Android again).
No unusual behaviour since then so maybe it was a coincidence.

[Q] Battery Drain When Powered Off

Anyone else encountered this problem ?
I've had my Nexus 4 for 3 days now.
I turn my phone off every night. So two nights for this phone. Each time I have turned it off it has been fully charged, with the battery indicator and a third party app both showing 100 %. The next morning (about 8 hours later) I'm finding the battery has dropped to ~85%, so losing ~2% per hour when powered off.
Anyone else encountered this or know how to deal with it (before I contact Google)
Note - to power off I press the power stud until the Power Off menu appears, select Power Off, then click on OK to shut the phone down.
This is with Android 4.2.1

It takes power to turn the phone on. 15% might be a little much but it is not unlikely.

15% does sound a little high. OP, how's the battery life during daily/normal usage?

Battery life has actually been decent, I think I'm getting better usage than my old HTC Desire Z with extended battery. I'm not a heavy user, though I have been using it for music at work.

It takes a huge amount of battery power to start the phone from complete off, this also skews the first reading of the battery voltage as it will be lowered by the draw of power to start the phone so the indicator will read lower than it's true capacity.
The best solution is just put your phone in airplane mode at night, and turn airplane mode off in the morning, this is more power efficient than shutting the phone down using "power off", and you shouldn't see any battery drain apart from a percent or so doing this.

Phil

You can tell you guys never turn your phones off Starting up should have no battery drain - never been an issue on any of my previous phones and PDAs (last one also being Android).
I rang Google and they had never seen it before but recommended draining then fully charging the battery.
Friday night I made sur it was fully charged before unplugging and shutting down - next morning on turning on - 99% - result. Saturday/Sunday the same (note SAturday i fully drained then recharged the battery). This morning boots up with just 82%.
Looks like either it can't work out when it's fully charged, else there's some disharge mechanism in place to protect the battery and that's causing me issues.

It probably wasn't really at 100% even it was reporting as such. The reporting is broken. So when you rebooted you saw the real battery level.

I was just about to start a thread on this and then saw this thread here. So I'll ask here. I travel overseas a lot. So while I am on the plane I plug the phone in while off to charge it. I hit the power button occasionally to check the charge and when it shows "Full" I unplug it and throw it in my bag.
2 days later, I come back to the US and turn the phone on and the battery is usually below 50% even though it stated it was fully charged when I unplugged it.
So how does the battery drain if the phone is off?

I just sent my first Nexus 4 in for RMA on this very issue (if left for long enough it would just fully discharge), got the replacement on Friday, did a charge cycle, charged the phone fully up whilst off, took it off the charger (the official Nexus charger btw), and let it sit for the last day, just turned it on, and it's at 60%.... W T F !!!
This is sooo totally bizarre! I can only assume that this is common to most Nexus 4 (what are the odds of me getting two bad ones - direct from Google - with the exact the same issue?), and that people just aren't noticing, as most people don't leave their phones off after fully charging, and thus just never notice, as the battery behaves perfectly normally under usual use.
I would gratefully appreciate it if people could put this to the test, so I know whether or not to RMA the second device or not....

Are you using a custom rom, maybe its only sleeping.

Can't speak for the OP - but for me, no on both devices - totally stock. The latest one, box fresh on Friday! Also, the phone is most definitely OFF, and not just sleeping, ie, I press the power button & choose the "power off" option from the pop up. Unfortunately there's no way to really test this, by pulling the battery...

Nah - I tested it multiple times on my first phone. One time I left it for over two days and the battery went from "reporting 100%" to being under 10% whilst turned off!! Also on all the charges - I deliberately would leave the phone on the charger for multiple hours, even after it was reporting 100%, as I had the same suspicion. Often I'd leave it to charge overnight...
I have never had this issue with any other phone, or with my Nexus 7 (which I have subsequently tested in this respect, and it is perfectly capable of holding a charge whilst off)

It's not so much that it's a practical issue, it's more that I'm worried that it might indicative of a larger hardware based defect, and I'm not happy spending my hard earned cash on faulty goods.
If it's a very common complaint/fault then I won't bother to RMA the second one, but if I'm just ridiculously unlucky, and very few people are experiencing this totally weird behaviour, then I'll take my chances on a third...
Also, I don't think it's too much to ask to be able to turn my phone off to prevent it from losing any more charge. I can think of a plethora of scenarios where this would be extremely useful...

I'm now convinced of three things.
1. Android 4.2.1 can not properly read the battery state
2. Shutting down the phone does NOT do that, but rather puts it in to a hybernate mode that still requires battery charge
3. There is a fundamental design flaw in the phone that part causes this.
Most mornings I find my previously shut down at 100% charged phone at only 80-85%, though occasionally it is as high as 97-99, but not often.
Oh and my ROM is stock, my phone is not rooted.

I agree on all counts apart from the first, as my nexus 7 and my Mum's Nexus 10 behave totally normally in this respect, both on 4.2.1 and 4.2.2 (both stock/unrooted, although the Nexus 7 was rooted/bl-unlocked for a time).
Also, I don't believe it's a miss reading of the battery state, as I often leave the device charging for multiple hours after it reports 100%, by which point it simply must be fully charged. What's more - if you leave the device off for long enough it will fully discharge! The craziest thing is that the phone's battery seems to drain quicker when it's 'turned off", than when it's powered on and sleeping. Seriously WTF.
It must be something to do with either the LG hardware, or LG specific code in the Google ROM. Obviously the phone is incapable of properly shutting down, which is pretty crappy for a so called "flagship" device. As someone who likes to have full control of their device, I find it more than a wee bit irksome, that I don't have the ability to completely shutdown my phone! This is also where the irremovable battery is annoying, because there's no way to test whether it's a hardware or software issue, although I guess I could try a custom ROM and see if it still happens.... however I don't really wanna root & rom if I'm going to RMA it....
I'm really interested to know how many other people have this defect and don't even realise it, because their phone is either in use or charging! I find it hard to believe that I could be unlucky enough to have got two uniquely defective devices in a row...
I'd really appreciate it if people could check their devices for this issue, both on stock and custom ROMs, see if we can work out whether it's HW or SW related...

You could try powering it off with the bootloader. After you power off normally, hold power and volume down, when the bootloader menu comes on use volume keys to select power off and power button to confirm.
I'm hard pressed to believe the battery in my device would fully discharge if left off, when the phone arrived the battery wasn't dead, I got about three hours of solid tinkering before it died.

That's a good point. Mine came out of the box at about 80%.... hmmm. It could be that once it's first turned on it won't turn off again... this is such an odd issue! I shall try powering off from the bootloader next time, I'd still love to hear if other people's phones exhibit this anomaly though...
I'm aware that it's hard to believe issue, but there's only one way to find out...
I'm also very curious to know if loading a custom rom might solve it. I'm far less concerned if it's a software issue, I just don't want to have spend £250 on defective hardware.

I'm 100% stock, no Custom ROM nor kernal (kernel?) and my phone WILL discharge if left unplugged and "off". Happens every time I come back from overseas. Fully charge it up on the plane (even left the phone on but in airplane mode to 100% thinking that it was a misread of the battery level when the phone was "off") and still the same issue... turn it on a few days later and the charge is down to 75% or so....
I thought I was losing it... but I'm not the only one...

Ha - me too! With the first one, I actually went into a weird sort of denial, where I kept convincing myself that I must of got it wrong, it just seemed so absurd! Eventually I put it to the test (multiple times) and realized that my memory wasn't as bad as I'd been trying to persuade myself and the phone was in fact discharging when "off".
Anyone else?
Just got the update to 4.2.2 and have got my fingers firmly crossed that it's now a squished bug... although somehow I think it's more likely an LG/hardware issue...

What you could try to do it charge the battery to 100%, hold the power button for 10 seconds until it fully shuts itself off. Leave it overnight and see the battery level is at the next day.

[Q] crazy battery drain in nexus 4

Hi all,
New to the forum. Sorry if somebody has already posted something similar. Tried to search but could not find any.
The reason I am here:
Yesterday night before going to the bed, my phone battery was >80% charged. In the morning I found my phone switched off. I had to restart the phone using the power button. The battery was at about 40% down when I turned it on.
I dont use the phone much through out the day, so it uses around 20% in a day(morning to night).
There is nothing unusual that I can see in the battery usage stats. Attaching screen shots for reference.
The graph shows a sudden decrease in the battery power. I am not sure if any sofware can consume so much of power in such a short time, unless there is a hardware issue or the battery readings themselves are incorrect.
This is the third time in the last 5 days that I found my phone powered off in the morning with a sudden fall in battery power.
I am using the stock android 4.2.2 with all the updates applied.
Can anybody please help me understand whats going on?

When it drops straight down it signals either a reboot or a power off. Something is causing your phone to turn off (obviously), it isn't just a battery drain issue. That said, it shouldn't drop that much if it is off.

Thanks josh, is there a way to debug whats trigerring the shutdown? What worries me is the sudden power drop? Could this be a harware issue?
There might be some safety mechanism which will shutdown the phone in case it finds the battery current is extremely high. I am just guessing.

The battery % indicator isn't completely accurate so whenever you reboot your device it tends to show as a lower value than before you rebooted it. I find that whenever I reboot my device the instant drop is then offset by a slower than normal drain as shown by the indicator. Obviously the drain is no different but this is just what the indicator is showing.
I wouldn't worry about the drop itself so much, just what has caused the reboot. I can't help you there so maybe someone else has an idea on how to figure that out, good luck!

Try flashing the stock image again; efrant's guide in my signature is the best & most educational way to go about it..
P.S. overheating will shut the phone down. Maybe some rogue app misbehaving? Long shot but could be it. Search for betterbatterystats here in xda, see if some app produces some crazy wakelocks. If not, go back to the top..

You can monitor with betterbatterystats.
And if you are rooted you can check the root features in advanced settings to see any alarm that occur.
This will help you debug the problem.

I wouldnt be worried about the battery drain.. That is usual for your situation as you hardly use your phone, the battery reading isnt always accurate and is most accurate after a reboot.

If your reallt worried. Reflash stock images fromm Google. Don't use toolkits and learn something about fastboot and your phone.

Nexus 4 switching off at night while charging

I know this has been discussed plenty of times but I just have some more questions of my own I'd like to ask.
So my N4 just switches off over night after being charged to like 95-100%.
It is usually fully charged (green LED) but won't turn on if I want to wake the screen.
I have to hold the power button for like 5 seconds for it to switch off. Then I am able to boot it again.
If i just unplug the charger, wait like 30s to a minute, the screen will wake, it works as usual. But the phone restarted (!!!) without any boot animation or anything. Just like nothing happened. If I then go into settings -> battery you can see the phone switched on just a minute ago.
This is happening like everynight for me now, so I had to use my old phone as an alarm clock as I slept in quite a few times actually
I searched like all forums and tried everything but I cannot dissolve this issue.
I even turned off deep sleep in dev options and stuff alike, monitored temperatures and stuff. Nothing conclusive though.
So I just have no idea why this keeps happening.
It happened with different roms and different kernels. Root or not rooted.
A friend of mine has a N4 as well and he does not have this problem at all. He does not have a custom rom flashed or anything.
But I read on other forums that even users with stock rom had this problems.
I think this is a quite common problem with the Nexus 4 device, isn't it?
Anyone solved it yet? Or does at least know the CAUSE for this?
I mean srsly there is like nothing on the forums..
Is it software related? Hardware related? Did I **** something up?
Is this a valid reason to send my phone back to google and get a new (working) one?
Everything else just works flawlessly. I mean the N4 with PA on it works so smooth like a charm.
I DO NOT WANT TO GIVE IT BACK!

noone? really?

I don't remember this being a common problem, though maybe I missed something.
If I was you I would wipe everything and re-flash stock. Then if it still happens return the phone, it shouldn't be doing that and I wouldn't put up with that if it was my phone. But it's your choice.

I have the same problem and I believe that this and similar issues are becoming increasingly mentioned on various sites on the net. XDA tread - http://forum.xda-developers.com/showthread.php?t=2077148 which gives some idea as to what people are doing to get to the bottom of the problem.
There is further info here - https://code.google.com/p/android/issues/detail?id=35139 which starts with Sleep of Death issues on JB4.1.1 (on the Galaxy Nexus but has more recently focused on the Nexus 4).
Initially the problem occurred maybe 3 times a week. I'm running a Stock N4 and whether stock or custom does not seem to make any difference.
I re-flashed a stock image and thought I had solved the problem. The phone ran okay for a few weeks and then reverted to random SOD's normally at night whilst charging. If I use airplane mode at night I have no problems. It has also become unresponsive/deep sleep on three occasions during the day. More recently I have stopped leaving wifi enabled unless I need it I no longer use airplane mode and have not had any further problems --- so far ---
For me at least, the problem might be wifi related.

This happened to me this morning. I have my phone on charge every night and it probably hits 100% about 3am every morning. I have the alarm set at 7am to wake me, and has done every morning since I got it last month. However I have now slept in twice (this morning was catastrophic) due to waking up to find my phone was switched off and my alarm subsequently didnt sound!! I have wifi left on, but all my apps are closed down, and only the alarm app running.
To switch it back on I have to hold the down the power button for in between 5-10 seconds for it to reboot.
Does anyone know why this is happening? The Nexus 4 is perfect in every other way, I'm gutted to find a fault after raving so much about it!

Same thing is happening to me every night !

I have the same problem, but it happens sporadically, so I never know when I'm going to end up sleeping in. It's infuriating.
It just happened again this morning. I had Wi-Fi disabled, so I know it has nothing to do with that.

I have the same problem, but it happens sporadically, so I never know when I'm going to end up sleeping in. It's infuriating.

Sounds like a rogue app is triggering the phone to crash or something?
Have you tried a factory reset?

This bs caused me to be late to a final exam... I was so mad when I woke up and saw that it was 2 hours later than the time my alarm was set to sound.. Only started happening with 4.4+ updates.

Factory reset?
Sent from my Nexus 4, while driving in my Evo9.

Hey man,
My girlfriends nexus 4 did this as well and she got it RMA'd with no questions asked and a brand new one sent out, they told her to do a factory reset; this worked for a few days then went back to normal again.

Charging cable
I have had this problem eventually with every android phone I've ever owned but it seems by replacing the charging cable with a new one the problem goes away. It seems that there is a weird thing with android where if the cable doesn't sit completely snug or straight the battery can charge but the phone won't realize this and go to sleep. Also seen the opposite happen where the phone thinks that the battery is charging and in fact it hasn't. When you unplug it suddenly goes from full charge to nothing. Haven't seen that last one on my Nexus 4 yet though. So I would try replacing the cable (not necessarily the charger) usually worked for me on other phones. Also I would suggest not to leave the phone and cable hanging off the end of a table. Make sure it's in enough that it sits flat. I think this is how I slightly bent mine.
