The way the story goes:
My girlfriend drops her N4.
The screen breaks and I replace it.
About two weeks pass and she gets the red light of death.
I do some homework, read few threads, watch few videos and try everything I found before I take device apart again.
Try pushing all the buttons I read about, while plugging the charger, while unplugging and standing on one foot and singing "Mary Had a Little Lamb" and other voodoo. No success.
Taking the back cover off and unplugging the battery. Connecting it back, closing the N4, try to power it up but no signs of life.
Suddenly I realize the device is very hot. VERY hot. I start taking it apart again, unplug the battery and let it cool. After that I plug the battery back again leave the back cover of, to check if the powering up process made it so hot. Well, no. After about 15 seconds I begin to feel the heat.
I decide to blame the battery from my own N4. I take my own N4 apart, try to get the battery out, but while doing it I damage the battery and it starts smoking. So now my device is officially dead too. My N4 battery goes to the trash and I think "whatever... I'll try her battery on mine.". I plug it in and the N4 stays cold for few minutes, I close the back door and it powers up flawlessly and now runs for few hours.
Since I she bought the N4 in the US she had no warranty here where we live, so that's the reason I changed the screen myself which voids any chances for RMA even if could figure a way to get it back the the US.
Meanwhile I ordered a new battery for myself.
Do you guys think it the logic board that's dead (If so, should I replace it?)? Maybe other part that just does short circuit? Maybe the battery got f***ed during the screen replacement and it just took time to kill the entire phone with overcharge or something? Any other ideas I didn't lay my mind on?
Thanks in advance for your replies!

so judging from your experiences it is not a dead battery that causes the red light of death problem?
i am wondering because i too have red light of death on my 2nd batch nexus 4 (ordered 11/27/12, delivered december 13 2012) and i too took it apart and removed battery for charging, this did nothing but i have a new nexus 4 coming from rma and i would like to swap the batteries and see if that will help because i would like to wipe the phone im sending back but idk if thats possible

I ended up getting a used motherboard from ebay for about 100$ and replacing it. Still works like a charm.
But I can't promise you anything, since it may be any other part that causes a short circuit and burns it. I just took my chance.
For me unfortunately the RMA wasn't an option.

i purchased one of those backup batteries on ebay from china, after about 2 weeks it came in.
upon opening it i compared it to my battery, the new one said htc inovation on it but looked like a knock off counterfit to me. so before ever putting it in my phone i put it in the included charger and started charging it. once it was complete i tried changing batteries and as soon as i put it in my nexus one the little led at the top right started flashing from green to orange, the screen wouldnt even flicker. as long as this battery was in, even if i plugged it in it would do this. i left it plugged in over night.
i really dont wanna wait for a new one so im wondering if there is a way i could fix it. im going out on a limb and suspecting that the charger that came with it is the problem, as it seems to be some weird universal charger. so for the past few days ive had a led attached to the battery and it still i not dead. once its completely dead im going to try to charge it with my nexus.
any other ideas/insight you guys can give?
I know you can get a bit of info from /sys/kernel/debug/battery_log
I'm not 100% sure on how exactly to interpret that though.
I've also had what i assume is a dud battery from ebay. Exactly the same issue - flashing orange/green LED. I'm waiting for them to ship a replacement. I guess I'm not really that surprised. It's not like it's a genuine battery. I was kind of expecting problems with it i guess.
yeah it reminds me of those fake louie vutton purses you see on the streets in big cities, says htc on it but i doubt htc had anything to do with making it.
i bought one just like it for my g1 a year ago and it worked fine, still works to this day with no noticable difference from the legit one that i got it with.
i got a refund but i hate to let it go to waste i wanna try to fix it. when i hook it up to the led it shines so its obviously giving power, but every few seconds or so the led flashes, im not sure if this is the battery or the fact that i have the led taped to the diodes lol.
did you get one of those universal battery chargers with yours? i got one that you have to slide the connectors to fit the battery and i have a feeling its about as high quality as the battery. im wondering if that had anything to do with it?
that's what mine did when it got dunked in water....
did you dunk the whole phone or just the battery?
ive noticed that the phone flashes from orange to green if you try to turn it on while its plugged in without a battery in. perhaps it means insufficient power?
just a heads up, i put the new battery i got into the charger that was included in my first backup batty the charger is this one from this same seller
http://cgi.ebay.com/Multi-Purpose-B...wItemQQptZPDA_Accessories?hash=item3efc5b5855
not only did it destroy the new battery but it melted part of it after litterally 10 minutes of charging.
BEWARE of that charger and probably that seller as well
it probably would have burned my house down if i had not smelled it before walking out the door

Hi,
I have ASUS Transfer I've treated a like a baby. I'll root my galaxy nexus and put 3 ROMs on it a day, and have dropped it a dozen times, once into the bathtub and last weekend when I camping it started to rain while I was asleep. The damn thing got waterlogged. I was able to dry it out on my defogger and had it working again within a couple days.
The transformer I rooted once, but I got some strange error after about a week every time I tried to install anything, so I decided to just frig with my phone and let my tablet be. Then they forced ICS down my throat and it was draining the battry so bad I left it connected to the charger, which got bent because I was using it all the time plugged in and occasionally forgot how short that cord is. I bought a USB extendor but it was too late, that stupid cable was already coming apart.
Anyway, it will no longer connect to the computer, and that was alright, I had FTP. I was going to order a replacement cable, it was getting dicey whether it would even charge or not. In fact, I called someone on Amazon yesteday that a reasonable price.
And then last night, I plugged it in and it made an electical buzzing sound while it was charging. I didn't really pay much notice because I have a power inverter and it was not drawing any more than usual. The next reboot though all it's doing is flashing the ASUS screen and then powering off and then deciding to power on again and repeat x1000.
I have an RMA # and I don't want the battery to be flat dead when I send it in or I'll get back a repaired tablet with a battery that will last half the time of this one. LiIon's hate being discharged and left dead.
Is there anything I can try besides the factory reset thing? I let this thing update itself back to stock firmware and lost root and never did put a custom recovery on it.
Failing that, does anyone know how to get this thing to just power off and stop trying to load. 1000 times is quite enough. I feel sick about this because I love the damn thing and this like watching a cancer patent wheeze.
Thank you.
May it rest in peace
If there's no USB, or anything and it's stuck, you just need to let the battery die :/
Your kidding right? Let it dieeeeeee
Make sure in the RMA notes you ask for a new battery too, Sorry, there's nothing you can do without USB and with a bootlooper Dx Unless you open it, which = void warranty anyway.
I am having problems with my Nexus 4.
History, replaced screen after phone was knocked out of my hand, probably damaged battery while trying to remove it, but everything worked once it was back together.
Screen broke again, and while working on that, I noticed the battery had swollen so ordered a replacement of eBay.
All back together now, but.
1 Phone does not state "charging" when connected to AC or USB charging, although the battery icon has the lightning bolt in it and the %charge does not drop while messing with the phone.
2 Phone does charge using wireless, but slowly, and status swaps back and forth between charging and not charging and the % will move from e.g. 40% to 35% as it says charging or not charging.
3 USB works for connection to PC.
I charged the new battery overnight, wirelessly. It got to about 90%, so slow charging, but seems to work. Phone is usable, everything seems to work. I connected it to PC and was able to use Nexus Root Toolkit to backup, the reset the phone, no change in charging behavior.
Booting into safe mode made no difference either. So it seems it is not software/firmware/apps that are causing the problem?
I guess next step is to open it up again and remove and remake all connections and check contact posts? Should I order a third battery? Or a new motherboard?
I searched here, but could not find anyone with the same problem.
Any and all help appreciated. Thanks in advance, guys.
Opening and rechecking connections and coating with contact cleaner has made no difference.
Phone typically needs Volume Down and Power button pressed to get it to start, then Power Button to select start option, then seems to run okay.
Battery still not reaching 100% charged, generally 70-80% after a full night off, using wireless (my Nexus 5 charges happily on same charger).
Ordered a cheap battery from China, not really expecting that to be the problem, but no other clues or suggestions for now.
Any update?
My battery is ****e now, lasts 3-4 hours and I need to turn off the phone and charge. It takes 4+ hours to charge when switched on. Charging via the PC you can forget it, it drains the battery if anything!
I'm thinking of buying the battery on eBay and doing my research on how to fix myself.
Phone not switching on and Battery issues
Hi,
I have been facing quick drainage of my Nexus 4 battery since past few months. Recently I had been keeping it on charge almost the whole day, and a full charge would last only 2-3 hours! Further, the charging was taking a lot of time too.
Today, my phone had already switched off due to low battery when I put it on charger. After the white charging icon appeared for a few seconds, the phone wasn't charging at all. I have tried 4 different chargers, but to no avail.
Can someone help me? Is there a guide on how to change the battery?
Any help and urgent help appreciated!
Zany!

It's possible some hardware was damaged when you took apart and put back together your phone. The USB board is a possibility, as is the back cover itself. These parts are pretty inexpensive, if you want to try buying a replacement, but that's just a shot in the dark.

Buy a new battery. Li-ion batteries are only good for a few hundred cycles or so (~500 cycles is the expected lifetime), and the N4 isn't exactly the best in battery life, so you can reach the point where your battery turns to crap within a year or so (or less).
Go to ifixit.com and look at the teardown. All you need to replace the battery is a T5 TORX driver (for the screws at the bottom), something thin and plastic (like a guitar pick or a plastic knife - they do make professional tools for this) to pry the back cover off, a tiny phillips screwdriver (like for eyeglasses) for the battery screws, and something to pry the old battery off of the adhesive holding it in. Double sided cellophane tape works fine for keeping the new battery in. When prying the cover off, go slowly. A little at a time, don't rush or force things. Or you might flex too much and crack the back glass. Don't forget to take out the SIM tray first.

Time for a new battery. See above.
My battery have started to swollen up a bit but not alot (around 1mm or less, but it is noticeable when not in a case, it can wiggle a bit from side to side but not alot at all).
I have already ordered a new battery if it is expanding more, but yet battery life is pretty good in standby but not getting more then 3hours of SOT. but since im mostly using the N4 for email's and texting its not a problem for me to get through a full day.
I'm having the exact same issue but I've never taken the phone apart. In the 20 minutes its been off charger it's dropped 11% screen off in my pocket. It also gets hot and shuts off.

That could be software/ROM related. It sounds like somethings keeping your phone going full blast instead of letting it idle.
Yup, trying going back to full stock (should always be first step if possible), and then you can go from there. If it doesn't happen, than it was a software issue, and if it still does than it is definitely a hardware issue. Best of luck.

With a swollen battery I strongly recommend you stop actively using the device. Swollen batteries can explode and that would not be good at all. I advise you to please not use the device anymore.

Third battery (original, suspect replacement, now China sourced replacement) has been working well, phone back together and preforming as new for the last few months
I've been having a few issues with my Nexus 4 on 5.1.1.
Twice in the past month I've had random Force closures of all aps. Facebook was the worst. But then it goes on to all other apps including the launcher.
First time that happened I did a factory reset and things went well. Yesterday it happened again while it was on another charger and I can get my phone to boot.
The screen backlight looks like is on when it's plugged into the charger and will go out if I hold the power button down for 5 to 10 seconds.
If I hold the power button down for 10 seconds when the charger is connected the LED flashes red till I take my finger of the Power button.
I've let it charge overnight (12 hours) and I've tried holding both volume buttons with the power button.
As well as Volume up and Volume down separately with the power button.
Is the phone dead? anyone got any ideas on how to bring it back to life
I've got a screwdriver set on order as I don't have fine enough star screwdriver to remove the internal battery connection. Which is my next step..
I think you are right to try replacing your old battery. Be careful while scraping it out where it is glued in not to tear it up too bad because it can 'splode. Might want to use a plastic card for that. I used a metal shim, an iOpener, and am much better now...

I'm going to try just unplugging the battery from the board first before I attempt to replace it.
Think it's time for an upgrade anyway.
Got my eye on the "OnePlus-X" as my next phone.
Removed the battery and stuck my multimeter into it.
It's got V output of 3.61 volts but amps drop off a cliff to zero as soon as I touch the contacts.
New battery arriving tomorrow.
i have the same problem with my nexus 4 dude. it boots when it is connected to the charger. basically it works like a desktop. I went into recovery mode and did a fectory data reset and wiped all the cache. Pliz help me proceeed. I kind have a hunch that its a software thing. did yours start working ater change of battery? Thanks ..

yes dude. i can go to recovery without it even being plugged in. I m pretty frustrated. I plan on giving it to the repair centre but he will charge me a bit high. Doesnt matter will let you guys know if I do find a solution.
Well my "new" battery arrived yesterday.
And it's getting sent back today!!
Got it through Amazon and when the battery arrived it looked ok but would not charge. I took it out to check the contacts and the ribbon came away form the battery! Looks like it was not soldered to the battery properly (if it ever was!) Just glad it didn't cause a short and kill the phone or myself.
Getting one from a different supplier tomorrow. Hopefully this one will work!

Please let me know! I've ordered a third battery just now. The first one was an aftermarket one, the second one was apparently a knock-off, this one was smaller than the original one.
The third one is hopefully a genuine LG one since the reseller is listed on LG their site.
Dam!!
Replacement battery arrived today. Looks good.
Installed it and the same thing is happening!
Screen backlight goes on. does not seem to be charging!
Now thinking the motherboard is buggered!
But I'll keep the phone on charge overnight just in case...
Damn that sucks to hear man. Hope it works tomorrow!
Now just searching freebe sites and eBay for any damaged cracked nexus4's I could scavenge from

No point in replacing a great phone if you can help it
As the title says, Phone won't turn on. There are no led lights at all. It does get warm after being plugged in for a little. I had jrkruse's hybrid_bra1 stock safetynet samsungpay...... rom on it. It was rooted. Very minimal processes running. I actually had basically everything stopped and greenify on. Phone was around 40% battery. I plugged it into charger, took my dog outside, showered real fast, washed a few dishes, then came back in to room within 15 minutes to my phone being dead and hot. It's never got this hot before even while rooted and plugged in with this rom on it. I have never had it get that hot. Was just formatted the day before and really bare but, that is what happened.
A couple battery apps I had put the batteries remaining life capacity at around 60%. It held a charge poorly. Even for 60% capacity it felt weak, considering how little I did on it lately. I am thinking the battery may have took a crap but unsure because it warms up when it is plugged in. I plan on getting a battery soon since they are inexpensive and replace it to try it out.
Just wondering if anyone here has any experience with this and can offer any advice.
Thank you in advance.
(I looked for a min or two for similar posts but didn't find much. Will gladly take down if someone can point me the way)
You say your battery was already outworn, It may have died. I think you should try with a new battery, Or take it to a technician who can test the phone's hardware to see if there is anything else broken
i've only had one similar case with an s3, which would turn of at random % of battery. But when plugged turned on. I replaced the battery and it worked fine then

funny story....
The mic in my Nubia Red Magic broke and I sent that back to hong kong for repairs like 20 days ago. Before the Red Magic, I used this galaxy s7 edge my friend gave me. I gave it back when I got the Red Magic and told him to sell it or something. Not much later, decided to buy it back off of him for $200 to give to my mother. She loved it. I had the gs7 edge with me exploring prepaid provider options for my mom when the Red Magic mic broke. So then I decided to borrow the edge from her till my phone got back and few days later I break this one too..
I feel naked without a phone for so long haha

I have the same rom, with charging issues. I don't think its the rom causing it. The s7e are getting old and the batteries are taking a toll with the age. My phone will charge up to 81 at night and stay there. I get better results with wireless charging so i just top my phone off during the day with my wireless charger. There is a code to reset the battery's internal memory, if i find the link on how to do it I will post here for you.

Thanks for reply and alright let me know if you find out. My phone had no problem charging to 100% Its just the 100% on the status bar wasnt 100% of the 3600 capacity from wear. My friend's also does the same thing as yours except his he cant charge more than like 24% haha. He just uses it as a plugged in music player in car.... I am getting battery in the mail tomorrow and will see what I can do.

A little late, sorry. lol.
Thanks for suggestion, however, I may have worded my statement incorrectly. I meant to say that My phone would charge to 100% and the status bar displayed it as 100% but, the health and total capacity of the battery in mah was not the maximum 3600 or so due to simple wear and tare. It isn't apparent within any stock android feature however, battery monitoring apps like accubattery gather statistics after several charging sessions and estimate the current mah capacity. Mine was much lower than the default oem stated value of 3600. So my battery could be charged 100% but the 100% is really only 2400 mah lol. It was obvious either way by noticing that after my time using it and the previous owner's bad charging over night habits, that the battery was gradually needing charged more often lol..
I did read about the calibration method before when I was first looking into the battery issues. It seems it is more often done after a new battery is installed.
I screwed up a new battery install at the last second. I had to stop due the tiniest little round metal piece coming off from a very light swipe of my plastic spudger.
It was a very small wire connector piece. Unbelievably irritating. I didn't even finish because I doubt it would work properly. I beleive it is for the rf cable or something not sure. The red one on the left bottom side of the logicboard/motherboard whatever. There are three of them.
I took it apart and put it together a couple times prior to this and in a hurry it popped off and I couldnt find it. I couldnt find out the exact part name online so I could buy one and solder it back on. I did find a site/ supplier that has a plethora of them though. They are tiny coaxial connectors/pins. I didn't look through them all but there are 6,000 some listed under coaxial connectors (RF). https://www.digikey.com/products/en/connectors-interconnects/coaxial-connectors-rf/437?k=coaxial pin
I haven't gotten around to asking samsung or the digikeys support if they could help me find out which it is. They have different sizes and frequency ratings or speeds and such. The phone is packed away until I manage to figure out which pin to buy or if I pull 80$ or so out of my behind and buy a whole new motherboard logic board haha.
