Nexus 4 Shuts Down Randomly and Battery Problem - Nexus 4 Q&A, Help & Troubleshooting

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 ?

Galaxy note update notification 26th July

Hi
This morning 26th on my note I had an OTA notification. Since I had no Wifi, I cancelled it. Now, when I do a manual check, it says 'no updates available'. I already have 4.04 (XXLRG) from an update a couple of weeks ago so it wasn't that.
Any idea what it might have been?
Hoping for some Jelly Bean soon since I like it on my N7.
Nigel
Omg. Seriously hoping this is foreshadowing the release of jellybean for the note...
Come on Sammy!!
Most likely not jb but to remove search the phone capability

Installing that much (really, any!) crapware along with updates is not cool...
But give me Jelly Bean quickly and I'll forgive you, Samsung.
So. Anyone know if this update fixed the battery problem many have? And fixed the issue of bricking the phone when hard reset?

The OP just said that all it did was install a bunch of crapware.
Nothing else.
And it's improved the performance..

Now now....can't use this without "value added software" because your user experience won't be as good
I got this update yesterday. However I can't find the apps mantioned here. It only said "Improved performance". I don't know what they mean. I have had the problems with the battery. I had to either pull the battery for a minute or two, or I had to switch on power saving mode right after charging and leave it on for some minutes before turning off powersaving. I had to do this every time I charged the phone, or else it would not go into deep sleep. It would stay on 200MHz, and drain the battery in a matter of hours.
However, this morning I saw (using CPU Spy) that the phone had charged all night using 200MHz (this might be normal. I don't know this). I tryed to just pull the charger, without doing the steps mentioned above. And i see now, a couple of hours later, that the phone has gone into deep sleep since I pulled the charger.
It might be too early to draw conclutions on this, but it looks promising so far.
I have found no info about the update yesterday. I hope its possible to hard reset the phone without bricking it now, but I don't know.
I will keep monitoring the phone, and let you know.

IIRC the phone doesn't charge during deep sleep, so clocked at 200 while charging should be normal.

That is normal and always was.
After you pull the charger it takes few minutes and the note goes into deep sleep.

I explained badly I think. I have used the CPU Spy for some time now, and i have seen that the cpu use 200MHz when it charging. Good to know this is normal. The big difference this morning was that when I took the phone off the charger, it went into deep sleep. It hasn't done that for a long time. Before the update, it went on using 200MHz after charging, when it was supposed to go into deep sleep. The only thing I could do to get it into deep sleep, was to pull the battery og use battery saver for a few mins.
I just hope they have fixed the brick problem when doing a hard reset too!

Yehh. I asked customer support what the update was, and if they fixed the battery problem and brick problem. They answered that I had to hard reset to fix the battery problem and the update was "improved performance". So I guess I either have to live with a bad battery or bricked phone hehe. Kinda hopeless imo. Anyways, the battery still works good after update :good:

[Q] Nexus 7 Battery?

hello guys, i had recently bought a nexus 7 16gb about a month ago, and while i was gone for the weekend, my little sister was using it. When i returned, she said it had completely died and she had been charging all night but was still at 0%. I've tried the common fixes that everyone has tried, but for some reason my battery says it will not charge, but yet i left it on the charged for over 6 hours and its still at 0%. When i got to Settings > Battery > it has been unplugged for well over 18 hours. is there any fixes out there or any way to reset the battery stats? i'm on 4.1.2/ stock non-rooted. can post screenshots if needed. i dont want to keep charging and risk overcharging my battery or anything like that. It doesnt get hot, make any weird noises or anything. Thank you in advance!
I think you have loose battery connector.
and please post questions in Q&A section (xda made it for a reason)

Sounds like a loose connection in the battery.
If you dare, pop the back open and then check the flex cable.
When she said that 'it has completely died', did she mean it just randomly went off when she was using it and the battery level wasn't empty, or did she mean that she had got the 4% warning and kept using it until it died? This is important.
If it was the former, then yes, the battery connector may have come out. If it was the latter, it's very unlikely its anything to do with the connector. I'm sure I've seen something before about a problem when someone has used it until it has completely ran out of charge until it switched off.

Ask her by the scruff of neck, did you drop my n7. If she say's yes, either send in for repair using your warranty or pop off the back. Since it is recently bought - probably better to use the warranty...
thank you guys for the replys, i dont think its a loose battery connector, i popped the back off and everything seems to be okay, i let it charge for like 8 hours and then have been playing with it for about 9 hours now, its what it says in the settings, but it still says the battery has 0%, but its functioning just fine..? idk, its pretty weird but its running completely normal..

thank you xateeq, Wilks3y, and knuckles, it was just a loose cable. Also, when i had the back off, i noticed there was 4 soft buttons but only three that are pressable (power, vol up and vol down). did they have plans to make a camera shortcut perhaps? also, i realized there were two screws that are missing out of the holes. is that a normal mishap on their behalf? thanks for the answers guys, just a little curious.

Yes, that's normal, because they caused the screen lift in the first parties of N7, and without them the issue seems to have been resolved

Yeah when you had the back off you would have seen the empty square bit where there was originally going to be a rear camera, before Google told asus to take it out of the design. Sure someone from the modding community will be working on that.... In fact i saw a thread where they found out what camera was going to be in there, and they were in the process of trying to get it in and working...

[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

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.

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...

i have had my current setup since i got the phone.. AOKP, Franco Kernel, undervolted -25mv, with like 215 total apps.... decent battery like, usually about 3 hrs SOT...
but yesterday was among weird to say the least.... Franco monitor will show my CPU was up to 170* at one point... but yet, my CPU usage on my monitor was with core 0-1 being less than half throtle while core 2-3 were offline... so i thought it was weird that my CPU would be so hot, yet not ON....it was so hot the phone would shutdown as soon as it got booted...
then my battery was not hot, but draining incredibly fast.... like from 88% to 19% in less than 2 hrs....
my battery usage pretty much displayed that it was the Screen consuming most of my battery.... i didnt notice GS being a problem, but im sure i would have noticed if it was
So far, i went ahead and factory reset, formatted /system /cache /data and dalvik... installed my rom again fresh.... its not acting up yet.... but for some reason i cant shake the fact its using battery much faster... i went earlier in my break from 94% to 87% in less than 10 minutes... thats not normal..maybe its just me..
so tonight i am going to reformat everything a couple times, install all fresh and see what happens before i restore everything back in the phone.

I'm with the same problem you're with. I did format everything, and the problem persists, can't really find the culprit on this.
I'm using PA 3.99 + FK, but I've tried with stock and cm, with stock kernels also.
Please let us know if you did solve the problem, and how did it, because this is becoming difficult to manage the use of this phone for me, having to carry the charger everywhere I go.

So battery life has been horrendous. It dies much faster and takes long to charge. My car charger no longer charges the phone... yet my Gnex and N7 FHD charges on that charger fine....
Qi charging works fine too (thats next to my bed)
So i called assurant, which sent me to Tmo, which sent me to Google (got it at play store) and they are sending me a new unit, since this one will be covered until manufacturer warranty for malfunction, not physical damage
Im sorry i will not have a resolution, i will revert back to stock and re lock it before i sent it back.... Hopefully i get a good one and not one with issues...

[Q] Please help me solve my battery drain $5 reward!

Hi guys
After two weeks of trying to solve this myself I'm completely out of ideas and desperate. My phone is an international d802 running on a strong Australian 4G signal.
No matter what I do I seem to be getting around 3%/hour battery drain when the phone is idle/sleeping.
I've been analysing with betterbatterystats and wakelockdetector and my phone seems to be deep sleeping 99% of the time yet the battery still drains.
It the past couple of weeks I have experimented with Stock LG, Cleanrom, Cyanogenmod and Omni as well as a custom kernel and the drain happens on all of them.
The test I performed last night involved
*Completely wiping my phone restoring the factory image
*Running setup and only installing betterbatterystats (wakelockdetector was installed this morning after the test)
*Disabled WIFI, BT, GPS, Location Services, NFC and Sync.
*Leaving the phone on my table unplugged but not in use.
*I woke up half way through the night the check the result and when I noticed it was still draining I disable data for the 2nd half of the night.
I've attached some screenshots of what betterbatterystats and wakelockdetector had to say ignore the flight mode I only put it in this mode for the last couple of minutes.

Any and all advice would be appreciated.
More screenshots. I only installed wakelockdetector this morning after the test to check what it had to say AFAIK it should still have accurate results despite this.
What apps do you have that sync?
Ur crazy and without signal.

For this test it should have been nothing as it was a complete fresh install with no user apps other than BBS. I manually disable all of google syncing in the settings menu. I've performed similar tests in the past couple of weeks with my normal daily driver setup i.e CM with a few apps running and sync/bt/nfc/wifi/data enabled and it produces very similar results.
This test was just an absolute barebones "control" test to rule out anything I could have installed so I was shocked to still see the drain.

I'm not quite sure what you are trying to say? If you are referring to the 3hrs of no signal in BBS that would be when I disable data for the 2nd half of the test.
Ok after another night of testing I'm at a loss.
This time I tested in flight mode the whole time which should rule out any sort of radio issues.
To my shock I lost 25% overnight at 3.2%/h screenshots attached.

Looks like u have a bad battery
Sent from my SM-N900P using xda app-developers app
yeah with data provided it can only be bad battery.
reboot and check for weird percentage jumps, just for fun. They might not occur, I would return the phone for service if I were you.

No its not. I usually drop about 2% in 8hrs with LTE on, being when I am sleeping and not touching the phone of course.
Oh dear this isn't great news though on one hand I'm almost strangely relieved as I've been going crazy testing every possible solution for the past couple of weeks.
Now the bad news. My phone is a grey import (so I could get the international model before the local model was released) so warranty/service could be a massive pain if at all possible.
I'm now looking into purchasing a replacement battery. The only one's I can find are on ebay for around $60 delivered and then I'd need to pry the phone open to replace it.
Is there any way I can 100% confirm it is a faulty battery before spending more money? I do recall certain tools during my testing describing the battery health as good but I don't know how reliable they are.
Voltage leak indeed. Could well be a bad phone and boot just battery.I may lose .1-.2% overnight airplane mode. Sry bud.

Riiight. So your phone without touching it, on LTE, will last you 16 days?
Just an idea

I'd have to agree with the majority here and blame it on a bad battery.
See if your location options are on, if they are, turn them off and try again.

You way read the whole topic with feedbacks, and you will maybe understand.
some people reported a good behaviour of battery. So maybe it could help.
Thanks for all the extra advice guys

Went to try that a a couple of days ago but unfortunately the dialer code doesn't work from cyanogenmod and haven't bothered to flash back to stock to test it out again.

Yes someone actually advised that to me on the whirlpool forums earlier so I did that very thing last night.
Just turned it on and it was on 98%. Not sure what to make of the result??
Bad phone or battery is the result.
