[Nexus 4 Q&A, Help & Troubleshooting] tacwold:
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?
[Nexus 4 Q&A, Help & Troubleshooting] tacwold:
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://xdaforums.com/attachment.php?attachmentid=1240843&d=1344068311. Consider buying it on Play in the future if it benefits you.

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.
[Nexus 4 Q&A, Help & Troubleshooting] tacwold:
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.
[Nexus 4 Q&A, Help & Troubleshooting] tacwold:
Thank you anyway ;)
[Nexus 4 Q&A, Help & Troubleshooting] Guiding.God:
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.
[Nexus 4 Q&A, Help & Troubleshooting] Rizy7:
Are you guys using the stock chargers? And charging through mains?
[Nexus 4 Q&A, Help & Troubleshooting] Guiding.God:
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.
[Nexus 4 Q&A, Help & Troubleshooting] toturi:
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.

[Nexus 4 Q&A, Help & Troubleshooting] Higgsy:
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.
[Nexus 4 Q&A, Help & Troubleshooting] gamepr:
Mine has powered off unexpectedly twice in 30 days. Should I get it rmad?
[Nexus 4 Q&A, Help & Troubleshooting] Higgsy:
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).
[Nexus 4 Q&A, Help & Troubleshooting] alexwhatpr:
I got the same problem ..just that my n4 back cracked while was charging :-\
[Nexus 4 Q&A, Help & Troubleshooting] damonhuang:
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 ?
[Nexus 4 Q&A, Help & Troubleshooting] fdbf:
Same issue

Same issue: phone shutting down brutally (goes of in an instant) and not turning on anymore. If you manage to turn it on, huge battery drain displayed, like in the pictures posted above. Furthermore, network signal is falling down often.

Already tried:

- Factory reset

- Cyanogenmod 10.1 M1, M3

- Changed baseband .33, .48

- Returned to stock android 4.2.1

- Tried Stock android 4.2.2

- Franco.kernel flashed

- wipe out of EVERYTHING, data , cache, dalvik cache

Result: NOTHING HAS CHANGED. Problem is always there. And it came after upgrading to 4.2.2

If anyone can find a solution to this, it would be great.

Thanks,

Fabio

Did you find out the cause? I have the same issue happened twice today
[Nexus 4 Q&A, Help & Troubleshooting] kal326:
My wife's phone has been doing the same thing the last two days. It was also sent back to LG for glass replacement. I have screen caps of the last two days where basically the phone went from 30-45% charged to zero and then turned off. Plug the phone into a charger and it starts charging from 0% like the battery was completely drained. Also since 4.2.2 I have noticed issues where both her and my phone will instantly show charged to 100%. My original charger drops to USB charging after a few minutes, using other chargers like the one for my Nexus 10 charge just fine AC all the way to 100%. So it seems there are charger and charging issues with the hardware. I might try a factory reset on hers to see if that fixes the drop off a cliff battery usage and shutdown. If not probably going to end up sending it back to get looked at again.
[Nexus 4 Q&A, Help & Troubleshooting] jeezess:
Another unfortunate soul with the same problem..

My story is this: Bought my Nexus 4 used from eBay (used for a month, no damage). Worked absolutely perfect for a good 6 months, until I decided to drink an excessive amount of alcoholic beverages, resulting in my phone hitting the pavement, flat on the touch screen/digitizer side. This resulted in a spider-webbed, nonfunctional screen. However, I kept the phone on to see if any other hardware issues would pop up. No such errors. Mistakenly, I forgot about the phone being on, letting it sit until it completely ran out of battery. I purchased a new digitizer/touch screen assembly and fixed it myself.

Side note: I have torn apart many electrical devices and have the (sort of) proper tools to do so. However, this does not excuse the fact that I could have messed something up doing so.

Once I reassembled the phone and tried turning it on, it wouldn't. This is the time when I remembered that I didn't shut it off, so I grabbed my charger (Note: NOT a stock charger. 5V/500mA - greatly under-powered, but works) and plugged it in. After a couple moments, the notification light began blinking red, letting the user know that the battery is too dead to even power the motherboard, let alone start the bootloader. I let the phone charge for about an hour, and the battery charge notification level said it was at about half-charge. I figured this was good enough, and turned it on to my relief of the new digitizer working perfectly. Things ran fine for about a week or two, when I started noticing my phone shutting down brutally at around 50% battery. Thinking this was some rogue app crashing the system, I plugged the charger in and turned on the phone, only to see that the phone was charging from 3%. This surprised me, so I let the phone charge fully. After the charge was complete, I unplugged the charger and checked my battery usage, noticing the shutoff at 50% and the sudden drop to 3% when turned back on.

Ever since then, it has gotten much worse, shutting down brutally at 95%, jumps in charge percentage when charging, repeated network loss.. Basically everything you have all described previously in this thread.

In a nutshell:

- Working fine until tearing apart phone to replace screen

- Brutal shutdowns at (software-indicated) high battery charges

- Extremely abnormal charging rates (sometimes no charge, sometimes 30% in a matter of minutes)

- Works fine when plugged in

- Using a non-stock, underpowered charger

With all of these things happening AFTER I took apart the phone, this logically makes me believe it is being caused by a hardware problem, NOT a software problem. I'm thinking it has to be a charger port/battery issue, but I'm afraid to spend the money on either to find out it's something else. I'm sending it to LG (not Google because I didn't purchase it from Google Play) to be quoted for repairs.

I'm hoping this thread stays alive, because at the moment, it's the most relevant and least filled-with-idiots thread about this issue on the internet. Please, PLEASE post solutions if anybody has found one.

Thanks,

Paul

[Nexus 4 Q&A, Help & Troubleshooting] lombardo8:
I have got the same damn problem and I have only had the phone only seven months. It seems to happen about twice a month. My one just shuts down when it still has enough battery power. It will only power on when I plug it in and press the power button for around 30 seconds. When it eventually comes on, you can see the charge is still there. It just happened again now and the charge was 64% when it came back on. I have also noticed that my LG supplied charger doesn't charge my phone properly. I plugged it in at 26% last night and this morning about 6 hours later it was only up to 84%. I have no such problems when I use other chargers from Samsung/Nokia.

I normally keep my phones about 18 months but I don't think I could endure this for another 10/11 months. Has anyone had any luck with Goggle/LG fixing this problem. I called my provider and they have asked me to send the phone in but I don't really want to send my phone off if they are not going to fix it

I Fixed This Same Problem With My Phone

My phone came to have this issue every time battery power read below 70% or so. It would try and fail to boot up repeatedly. Then I would connect it to my laptop usb for power, and it would boot instantly. Disconnect, and it would stay on for an unpredictable while, and switch off again under use. I could reboot with 90% power and it might read 82% when it rebooted. A few times hours would pass, and the readout would not change, like the battery wasn't draining. I figured there must be something wrong with the battery. Well there must have been, because changing the battery fixed my problem. One week in and my phone is like new again. Here's how I did it:

Watch "How to disassemble the Nexus 4" You Tube video. (I only swapped out the battery, so that's all I needed, but this video could be used to replace other components)

(wwwdot) youtube.com/watch?v=AZDAIgwbXk4

Ordered the battery from Mobile-Cherry. $13.80:

(wwwdot) mobile-cherry.com/products/batteries/new-bl-t5-battery-for-lg-optimus-e960-google-nexus-4-optimus-g-e970-e973-2592.htm

Once I received the new the battery, it took about 20 minutes to complete replacement. I could do it again in 10. It only takes as long as it does because you want to take your time and not break anything. Follow the video, and you can do it. Remember to take your time.

My Nexus 4 power-down mystery is now solved. Hopefully the problem was confined to the battery and there's not an issue with the phone that will cause this battery to suffer the same problem. I bought a new HTC One while my Nexus 4 was down, but it's sitting on a shelf waiting to be sold on Craigslist. I love my Nexus 4.
[Nexus 4 Q&A, Help & Troubleshooting] schrock:
Mobile-Cherry is $20 in shipping for this battery. There is an option for "HK Post Office / Free Shipping" but its 15-20 day delivery time. I took the free option. Site looks a little sketchy to me. I will post back here with the results in 2-3 weeks lol.
[Nexus 4 Q&A, Help & Troubleshooting] xvanwaart:
Had the problem every day now and it was getting worse... Replaced the battery just now. Will let you guys know how it works out. The undersite of the origional battery looked a bit strange and worn out...

*Update 2/8 09:40 CET* Now after 4.5 hours of heavy use, WIFI on, poor vodafone reiception so a lot of network changes still 85% and going strong, no reboots. Looking good!

I have all the symptoms reported here and am in the process of replacing the battery. I just took the old one out and it is clearly not in good shape. It is bulging in spots and appears to actually be leaking. It has a sickly sweet smell and a quick google reveals that is probably the electrolytes used in the battery. I am quite hopeful a replacement battery will resolve my issues.

Hi Guys,

I thought I should also chime in as well, since I am quite disappointed to hear the battery is leaking. I have the same problem and have purchased a new battery which should arrive tomorrow. I feel I have a battery leak as well since I tried to smell the headphone jack and smell something weird. My phone just shuts off at 80% battery, then when I try to reboot it, its at %60. This is so concerning, since I upgraded from a nexus 1 which never had this issue. If multiple users are experiencing battery leaks, this is most likely a defect of some sort. It hasn't even been a year since I purchased this phone, probably should of waited for an HTC one google edition.

Just an update that after replacing the battery, I have great battery life. Seems pretty clear that my particular issue was with the battery itself. Hope this helps others.

[Nexus 4 Q&A, Help & Troubleshooting] jsax:
I used mobile-cherry.com which was recommended by someone else here. I will say shipping was quite expensive and took almost 2 weeks to arrive to USA from China. If I did it again, I might look into newpower99.com which I didn't find until I had already placed an order with mobile-cherry.com. The newpower99.com kit comes with all the tools you need, which is nice. Don't know where they ship from or how much shipping costs though.

ive got the same problem

so first i smashed my phone screen, and i replaced the screen about 2 months ago.

about 2 weeks ago i get the update for 4.3, and then i get another update for 4.3.

after i get those updates this starts happening:

Battery reaches about 35% and then the phone signal is lost.

The phone then blacks out and turns off.

I turn it back on and it says shutting down - low battery.

As soon as i plug it into the charger it says 25-30% battery?

Is this a software problem or hardware?

PLEASE HELP!
[Nexus 4 Q&A, Help & Troubleshooting] Simonna:
Maybe try a new battery?
[Nexus 4 Q&A, Help & Troubleshooting] nightraver:
I have the same problems. Two months ago I dropped my nexus, glass was broken. I replaced the screen myself and the phone was working perfectly again. Since the 4.3 update, at 20% battery, I have to enter my pincode, few seconds later, phone goes black. When I try to charge, a red notification led is visible. When it charges for a few minutes, the phone can be put on again and battery state is 0%. It happened once it started charging from 20%.

Glad I found this thread and will be ordering a new battery.

I guess it has to do with getting the battery out when you disassemble the nexus for the screen replacement. With all the glue, it was hard to get the battery out. So I think it is easily damaged in the process...
[Nexus 4 Q&A, Help & Troubleshooting] marocampos:
Dropped my phone, changed glass and yes, I have the same battery problem. I think it's related to the process of take that battery out to change the glass. Maybe it gets damaged... Just ordered a replacement.

Shutdowns as well

My n4 shuts down as well on 4.3 stock as well, I don't have such extreme differences in battery Im using battery widget reborn and it looks like it dips some when the phone comes back on. I'll take a screen if it happens again. I'm on wifi and I deleted netflix today after finding out it could be a problem. Rebooted after and it happened again.. Ive only had the phone 3 days now. Seems to only happen when the screen locks though.

Edit: So I cant attach screenshots, but it just happened again and my battery dipped a little bit. looking at its history it looks like a bunch of stairs.

[Nexus 4 Q&A, Help & Troubleshooting] Devhux:
This is not a thread I should have looked at after just getting my phone. I'm wondering just how many of the "Red Light of Death" cases are related to bad batteries, and if so, how many batteries have actually started leaking.

I realize that the majority of people are probably fine, but if this was a laptop and batteries started leaking or bulging a lot, there would be a lot more investigating done. Heck, I could take this further and guess that some people who've said the back glass cracked on its own could have been related to a faulty battery pack that bulged a little too much (causing the glass to bend enough to cause breakage).

Yes I realize I may be grasping at straws, and I certainly hope I'm wrong, but it does make me nervous being a new owner of this phone and seeing just how hot it can get.
