Nexus 4 Shuts Down Randomly and Battery Problem

Help people, I have the nexus 4 for over 3 weeks and great but a few days ago when it was nearly full battery (around 80% or so) suddenly shutted down and I couldn't turn it back on until after 1 min or so plugging in. I did not care about it the first time ... But today, after having it charging about 2 or 3 hours I disconnected the cable to use the phone and the battery dropped from 90%+ to 8%, so I connected the cable and put it back to 100%, used it for 1 hour and it suddenly dropped back to 2% from 80% and then shutted down instantly.
Here are some screens.
Help please, and yes I have used the search function, but didn't find the solution on other posts.

What apps have you installed lately, maybe there is a rogue one. Install BetterBatteryStats for app behaviour and Cpu Spy for deep sleep issues.
Are you rooted? Custom rom or kernel? Undervolted or overclocked?

I'm not rooted, all at stock. I didn't touch the voltages, I didn't do anything. I installed some games (vector, pudding thd, order and chaos) evernote, mega manager, pulwifi.
I'll install betterbatterystats and cpuspy, thank you.
Edit: look what happened to the battery now...
Also I attached a pic of the cpuspy, I can't install betterbatterystats because it costs 2 dollars

I think there is a free version of BBS on XDA , here http://forum.xda-developers.com/attachment.php?attachmentid=1240843&d=1344068311. Consider buying it on Play in the future if it benefits you.
Battery levels can be inconsistent at times, especialy after deep sleep.

I see nothing abnormal on usage, just use the phone and see if this behaviour continues. If it does better do a factory reset or reflash the latest factory image.

Okay I'll uninstall the latest apps I installed and will use the phone normally, if this happens again I'll do a factory reset and if the problem continues I'll call google. Thank you :good:

I wish I could be more help but I had the exact same issue. I could not figure out what was wrong with it but I had previously broken the screen and sent my N4 back to LG for repair. Since it was still under limited warrenty from that repair I sent it back to them again. They said they replaced the charger connector. I got it back and it seems to work fine now.
My issue started after I updated to 4.2.2 I believe. I don't know the root of it but my advice would be to do what you said and call Google or LG.

Thank you anyway

Similar issue here - I've been using the same apps since I first installed them after N4 purchase (meaning no new apps/games installed in the last few days and no settings changed). Took a nap for a couple of hours and woke up to see N4 completely dead - 0% batt. Charging it now and looking at partial wakelocks etc, havn't seen anything out of the ordinary. Hopefully it doesn't occur again but in the meantime still looking for a reason why this would suddenly happen.

Are you guys using the stock chargers? And charging through mains?

Yeah, am on stock JB 4.2.2, unlocked and rooted though, no other change like new roms flashed or anything. I use the stock charger and charge through mains.

I think there have been a few threads with this issue and nexus4s even prior to 4.2.2 and supposedly it was hardware. I called support while talking it through she had heard a few similar cases and it seems to be a hardware/software design issue. My wonder is how can I enforce 'never deep sleep' because my kernel doesn't seem obey.
I woke up this morning with the indicator light on but phone dead requiring reset (charged though - if not overly so). Just now it died again while sitting on my desk at 80% charge and deep sleeping again.

I've read in a few places today the stock charger has been causing a lot of the charging issues and plan to switch to my old g2's charger tonight

Just RMA'd my nexus for powering off for no reason - would do it a few times a week (and extremely buzzing earpiece - which I was living with), never had a problem putting it back on though or had issues by battery levels being eratic) did quite a bit of testing over the space of a few weeks and found it continued to do it after wiping/fomatting everything and on Stock 4.2.2 non rooted and locked BL. As far as I am concerned if its still doing it with the stock out of the box set up its a hardware fault.

Mine has powered off unexpectedly twice in 30 days. Should I get it rmad?

Dunno about that its up to you mine was doing it 2-3 times per week. I would wipe everything including userdata, reflash stock rom and monitor before going through the rigmorole of the RMA to make sure its deffo a hardware fault. Biggest problem with the RMA is the fact they put a hold on your credit/debit card for the price of the phone. So basically if you don't have the funds available you are shafted (I think you would have to send off to LG in that case).

I got the same problem ..just that my n4 back cracked while was charging :-\

maybe you should try to flash other kernel and rom if you cant solve this issus. if your N4 is unrooted then just bring it to LG store, you got warranty rite ?

Pretty sure I bricked my Nexus 4

I don't know how I did it. I've been rooted/unlocked for over a month (running CM the whole time) with stock kernel. Last night I upgraded to the 03.24 nightly and everything was fine. 3 hours later I downloaded a franco kernel after some reading and I wanted to try it out. I used Rom Manager to reboot into recovery (like I always do) and install the kernel and as soon as I hit "restart now" apps started FC'ing and my phone never came back on. It never made it to recovery mode or anything. It just died completely and I was around 40-50% battery life.
Currently this is what I'm dealing with:
Holding the power button down for 10 seconds flashes a red LED light. No changed on the screen
Holding any combo of the volume keys (up, down, and both) + power does the same as above
The only time the LED flashes red is when I'm plugged in via USB or AC. Otherwise nothing
I've had to charging for nearly 10 hours now... it's like it has no power at all
When plugging it into a PC I see "QHUSB_DLOAD" in my device manager.
I have the Android SDK and Nexus 4 drivers installed
I have seen NOTHING On the screen since this has happened - no charging animations, fastboot, not even a flicker
I've down A LOT of reading and the only thing I haven't tried is charging it for days at a time and taking it apart (which I'm not opposed to doing) but I'd prefer not to. Is there anything else I can try? Thank you

Sounds like you flashed the franco kernel for the Nexus 7. You aren't the first and probably won't be the last. Unfortunately if you see QHUSB_DLOAD its dead.

You can try to get Google to RMA it. Yeah man, its bricked. Next time make sure you look at what your flashing.

That's what I was afraid of... do you think this is legit? I saw the video and it looks good. Says it fixes phones that don't boot at all. I e-mailed and asked them about my situation but I'm curious if you have heard anything about them?

Not to be an ass but it's his fault for flashing the wrong kernel. Google shouldn't have to pay for his mistakes.

Most of them are pretty reliable. The one that you linked to, they have their own YouTube channel where people have left pretty positive comments. They seem legit. I'd try them out if you want to be nice and not RMA it.
https://www.youtube.com/user/MobileTechVideos

Yeah its really legit. I got my HD2 Unbricked from there. I flashed a wrong radio and came back with a "RESURRECTED" Bootloader and just flashed a new rom. Its probably different on the Nexus 4.

I got the red light of death, just charged the phone for around 8 hours and it came back.

[Q] How to fix strange battery behavior?

Since last week I am experiencing a really strange behavior of my battery.
Sometimes my phone (in a random app) just vibrates, the screen goes black and then it reboots. After the reboot I have lost 40-50% battery life. Sometimes the phones isn't even able to complete the reboot because it spontaneously has too little power left. See attached screenshots.
Has anybody had similar problems? Or knows a solution?
About my setup: The problem seems to be not rom or kernel related. It occurs no matter what rom or kernel setting I am using. Currently I am running coool boy's 4.3 GE witch KT's kernel (no OC or UV).
Is it possible that the battery is physically damaged? I have NO IDEA...

Experiencing the same problem. I've flashed back to stock and still experiencing this. Phone randomly turning off, not starting, sudden battery drops. Driving me crazy.

I've seen the same sort of graph on my old i9000. You're not gonna like this, but it got worse over time, and eventually my battery wouldn't last more than 5 mins. I thought buying a new battery would help, but it didn't. When I sent it in to Samsung they said they would have to replace the entire motherboard...
I think it's got something to do with the motherboard not being able to correctly sense the battery voltage/whatever/%. The phone reboots automatically because it thinks the battery is flat (even though it isn't).
If you're under warranty I suggest sending it in soon... Hopefully it's not the same as what I had heh.

Well *#!$
I'll observate it for the next few days and see if it's getting worse...

If your phone is rebooting as opposed to just powering off, then I suspect it is hardware related (motherboard) as already mentioned.
I do hope I'm wrong though.
Maybe try using it for extended periods while plugged into a charger and see what happens. If it doesn't reboot then it may just be the battery.

Right as OP I'm suffering the same exact problem or there abouts. I've flashed back to stock rom, fully charged to 100% drained to 0% back to 100% yet still phone keeps shutting off randomly and the only way it works properly is with the charger plugged in. It's escalated quite badly with now after a few mins of YouTube turning itself off and not rebooting. I've requested a repair by o2 who I'm in contract with and see what will happen. I've heard crap stories about their repairs before taking it to Samsung.

I9500 owner. Had this exact same problem when using older firmware. After updating to the latest one, never had this issue again. Its been two months now, even more.
Try this. Flash the latest available firmware for you phone, not talking about OTA but the downloadable one from any region (whichever is latest for i9505). I guess it may have something to do with the kernel too.
Edit: wait a minute, why is your battery level going up when it isn't even charging in the second screenshot. Middle of the battery timeline. That's weird. I guess you should send the phone back

Thank you guys :good:
In the last few days the problem occurred more often. But now it is just shutting down (no reboot after vibrate) and after plugging it to the charger and restarting it sometimes I haven't lost any battery. Strange!
I fear there is nothing else to do than turning it in (warranty)

Same problem here. It started three days ago and today I'm barely able to use it... I'm still on warraty and I even have insurance, but it's a major inconvenience anyway.

Mines gone in for repair back to my carrier still no movement despite them having it for 2 days now really should have sent it back to Samsung directly. Will keep you guys posted.

Will send it in tomorrow. Lady on the hotline told me apparently the motherboard is defect and I'll get a new S4. Exchange, no repair. I'm fine with that...

That's good to hear, just inconvenience but at least you won't have to pay for it (or have the defect materialize a year later or something)

Hey
I am new here.
but i was looking for information becuase my s4 9505i has the same problem
shuts of almost everytime i open apps too quickly or stream youtube or some other high usage apps etc.
battery drops up to 50 percent then back 40 percent then to 0 percent, the fact it that the phone never seems to know where the battery is.
by the way my phone is not rooted and i have done the factory reset a few times.
samsung... hmmm.. they seem to be real hard to talk to on the phone, i have had to call them 4 times already about the s4 i ahve had since june, and they just play me off like i am some kind of idiot etc. and deny that there is possibly any reason for random shutdowns, phone freezing, and now this battery/motherboard issue.
next bit is kinda stupid, the phone has a few internal scratches on it from when i ahve stupidly had the phone next to keys and all that. im sure they are going to try and void my warranty and say i have mistreated the phone...
had many phones before, maybe close to 50 and never, never, never have had to ring up a company to try and complain etc.....
any ideas.
I am in Australia,
I am thinking of trying the CONSUMER AFFAIRS kind of threats, but i have to word it the right way...

[Q] Vertically jerking screen problem anybody?

Had been very pleased with this device in the the three months that I've had it. Until yesterday that is.
Basically the screen is jerking up and down on its own. When looking at the homescreen, the only way I can think to describe it is it's like 60% of the screen starting from the bottom is moving up and down by about 2mm on its own. I can see it eating pixels as it does so (it eats into home screen shortcuts). It also does this jerking motion when in an application or using a the keyboard.
I haven't dropped the phone, it hasn't got wet. It is completely stock unrooted and was bought SIM free in the UK in December and not tied to any network.
Things I've tried to fix it :
1.Numerous reboots.
2. Uninstalling the couple of apps that I'd installed around the time I noticed the problem.
3. Just done a full battery drain and now giving it a full charge keeping it switched off to see if does anything, (can't say I'm hopeful).
Next step is to back up / get my data off it and do a factory reset. Despite the bloatware, the stock ROM isn't too bad.
I was also thinking of just rooting it and running a cyanogen mod also.
Would be great if anyone has any ideas what I can try or if they've seen this issue before and remedied it. I can't find anything in Google and I wouldn't be surprised if it's just a random bad luck hardware problem -- which is worse than it might be on account of living in Southeast Asia -- but the device was purchased in the UK in December. Anybody know if there is such a thing as international warranty for LG phones ?
Thank you in advance.

I wouldn't root it send it to lg it sound like a serious hardware problem the g2 seems to be plagued with problems

Yeah I won't bother rooting it. A factory reset has made no difference and it's actually worse now and totally unusable, the screen just pogo's / jitters up and down an inch at time constantly.
The phone was bought on 22th of December, I'm pretty annoyed at getting little more than three months out of it. It would be understandable perhaps if I dropped it, or it go wet, none of these happened and the hardware has just failed for no reason.
For sure the LG repair centre where I livein Bangkok won't want to know as it was bought in the UK. And no doubt I'll get slammed for import duty both ways together with eating the postage sending back to the UK. I think I'll feel better taking a lump hammer to it and make a youtube stating what I think of £400 phones that last 2 months and carry no international warranty.

Have you dropped your phone?

Yep it is sad I hope my g2 doesn't go through the same thing i will definitely get a backup device sooner than later but like I said earlier the g2 seems to be plagued with problems which means the nexus 5 prob has the same problems maybe maybe not I'm a little nervous now because in the us most of us buy our phones locked with contract in the UK everybody buys there devices unlocked without contract from what I've heard if your looking for a new device I would wait for the xperia z2 looks very nice

Hello, same problem with me too, mine screen starts to jittering (like there is an earthquake inside my phone) after the latest update for kitkat, the updates says for optimising apps and such.
But recently i realize if i block my mobile data, and only using wifi for the data transfer, my phone stabilize much much better than when i used GSM/3G to do internet activity. When i used 3G my phone jittering like crazy, sometimes bottom half of my screen is gray pixels and bottom up of my screen dancing like crazy almost 70-80 % of the time. But when i block my mobile data and using only wifi, 80-90% of the time is OK, still a bit jitterish, but waaay much better.
There is also member of this forum experienced this and suggest to full cycle charger for couple of times. He say his phone stabilize after do full cycle charger (depleted ur battery until conpletely empty, than charge to 100% while turning off the phone). Im trying it tonight.
I also consult with some cellphone tech support (in shopping mall). They say maybe when i did my update, there are some data corruptions, so my phone did not update properly (corrupted). Because when you factory reset your phone, people said that it retain the latest update of software. So if you already did a corrupted update, it will stay even if you factory wipe the phone.

Seizure ?

It's a hardware issue, it's been discussed on this forum dozens of times. If nothing helps (including updating to the latest available version), send it in for repairs.

Im taking it in on LG Service Center this morning, the tech guy said its Hardware problem, about some sockets loose or something like that, He fix it and because im still have the warranty, so its free, no idea how much if the warranty is expired. And i still retain the KitKat OS (4.4.2). but my data is wiped out.
So far no jitters... I let you guys know if the jitters comeback.

Op...sounds like you have a faulty digitizer have you sent it in yet?

After 15 months own this phone, now this problem came to me too so unlucky because this happened after my warranty end...
Such a beautiful monster with so many hardware (screen or lcd) defects

I got same issue recently for many days, typically starts after turning screen on. Finally got it fixed by discharging fully and charging back again. No issue now. And I try not to charge phone too often only when battery is close to zero. Try charge and recharge a few times if it doesn't work. Works for me ?
Passing this on so others can benefit.

[Q] Nexus 4 sudden signal loss, battery drain and shutdown!

Hi all,
First post so go easy :angel:
I've had my N4 for about 18 months. Ever since 4.4.3 (now on 4.4.4 and nothings changed) I think I have been having some probelms.....I also dropped my phone around the time of the update so can't rule out a hardware problem, anyway....
On full charge the phone is, after a random amount of use perhaps around half battery, it drops signal completely....then it start goiing crazy, opening apps clicking on things (sometimes locks up) then shuts it's self off.
Once I turn it back on it says the battery is almost out.....even though before the crash it was at 50%???? (Please see imnage below for "cliff edge" on battery screen shot!)
I have tried safe mode, I have done a factory reset and removed all and any apps except facebook. Other symptoms include forgeting wifi and other account logins!
Also worth noteing I dropped it and smashed the screen, I then had it repaired and voided the warrenty (?) because I needed it same day for work.....dont know if thats connected was working fine for a while after this happened.
I have seen various posts of this forum and other about this kind of thing but no exact answers.....any help would be great 7 months until free new phone
Sudden drop is extreme right....

Re flash factory images for a full wipe, if it doesn't work after that then its probably hardware (sadly), maybe you could get a moto g? I've heard there really good and cheap.

Sounds like something went wrong during the repair or drop and that this is a hardware issue. As suggested, try flashing full stock, but I am pretty sure this is a hardware problem, unfortunately.

Thanks guys .....Ive been doing as much reading as pos.
Some people are saying reather than the drop its maybe just a failed battery? thoughts?

It could definitely be a possibility. If you are up to it, you could purchase a new battery and try to replace it, there is just the risk of damaging something further.

Same things happen to me. I thouhgt the battery is comming to end and orderd new one but I have read that people have some similar problems after updating from 4.4.2
On nexus 5 people also have problem with to fast battery drain. I have similar problems. I lose network, afterwards battery drop from 20-40% -> 0%

Not that I'm any expert but I think that your battery might be damaged

Same thing is happening to my wifes NEXUS 4. Hers is a little over a year old now. It was dropped and I replaced the screen a few months ago, but ever since the new updates, her phone has been going CRAZY!
The phone randomly loses signal, battery drains quickly and apps open close (ghost touches) and then it shuts down.
I've cleared the cache, reset to factory defaults and even run in safe mode and nothing. The phone is useless now, she maybe gets 2 hours of normal use out of it before it goes completely nuts again.

One of us should roll back to 4.2.2. and report the result

Facing similar issues. Have posted it here. http://forum.xda-developers.com/nexus-4/help/fast-battery-discharge-t2799931/post53790262?nocache=1
Any solutions?

I am waiting for a new battery. Try rollback to 4.2.2.

ITs same on my phone after an 4.4.3 update teh N4 gone rogue before the update it was working just fine I just did factory reset got back to 4.2.1 android and its doing the same

Just to keep you up to speed...I suspect it may be the battery....or perhaps power management issue/conflict??
Trick is if I keep my battery charge above 60-65% it's fine......get below that and the trouble start.....weird. hvaing said that seems to drain faster than normal also. My hope are pinned on battery solution once Rajnus trys it.
Although not looking foward to taking phone apart to replace it

Today after the first symptom I rebooted phone and after reboot my battery was at 14%. It looks like to me that we have constant drain but system some how is not registering it properly. I will restart after every 10%
Edit: 85% ->reboot -> 57%

I'm glad to see I'm not the only one suffering from this issues as well. I replaced my screen and digitizer about 3 months ago and never had issues. Last week I updated from 4.4.2 to 4.4.3 (and 4.4.4 shortly after) and started having the same issues where there would be ghost touches on the screen once I got to around 70% battery, loss of radio/signal, and when I would restart the phone, I would lose majority of the battery charge. I tried flashing stock back on the phone and the problem still is present.

Just to repeat that is exactly what is happening to me word for word.
