I posted this to reddit before here, but it will probably get more exposure on this board. Basically:
I seem to have stumbled upon a manufacturing flaw in the Galaxy Nexus's motherboard battery. Because I couldn't get a free exchange, I was free to open my Galaxy Nexus.
It was my hunch that battery pulling the motherboard's battery [which is basically like a CMOS pull in a PC conceptually] to reset it and get the device to boot.
Before that, the voltage on the battery was checked and it was already down to 2.4 for a device purchased in March. There are but a few months left on this battery and would have to replace it inevitably.
After searching the internet, this has appeared to happen to many people, but has never been addressed in this manner. So, this may be a real issue where poor sets of batteries have gone onto the GNex motherboard.
Unfortunately, I did this repair on the fly late last night, so I have no pictorial evidence. My next step is to identify the battery used on the device, purchase it, and do the solder job required to install it. Of course while taking proper documentation for evidence.

Any luck with this? Mine just happened to die on me after a couple of months of ownership. After I had it looked at, the tech informed me that I'm getting some sort of short on the motherboard. This is really a damn shame since coming from an iPhone, I really enjoyed this phone for the short period of time.
Trying to resurrect the ole' Gnex that silently slipped into blackness. Did you ever find a source for these little CMOS batteries?

It seems like its a hearing aid battery. I wouldn't be able to tell without pulling it out.

I am in trouble about battery.
Repeating "Charging" and "Discharging" without plug-in.
It is the main reason why it is so fast to be out of battery.
My battery sensor is something wrong.
Please tell me how to make my galaxy nexus recognize ALWAYS discharging.
Even if it is pug-in, it is ok that it recognizes "discharging".
help me.
Factory reset or get a new phone
If you are rooted, I would consider trying to rest your battery stats. There are several apps for this, and you can also do it in cwm

You need a new USB-board. Mine was not repairable, I had got some water in my usb-port. Not covered by warranty off course. A repair would cost me 150-200 Euro.
So I bought a new board online and exchanged it myself. Cost: 35 Euro. But you could most likely find it cheaper. Took me 15 minutes to fix.

Same thing happened to me. No water damage, no dirt, no filth, never been dropped. I take exceptional care of my electronics, I'm pretty ocd actually. I had to send it to Samsung for warranty because I didnt know the cause. And to answer your question, yes that's why your battery is draining.

Thank you very much
Thank you very much.
I never know that so many people are in same trouble.
Then now I do is Factory Reset.
I think it was caused by water.
It flowed into mine.
Second, I will buy the repair parts.
Thank you very much.

be careful if you wanna repair on your own.
my gnex had discharging issue, but shows lightning bolt icon at the top.
i ordered the part, and replaced it. but still has the issue.
factory reset didn't help.
Does samsung still take my gnex even though i opened it?
I'll try to make a short story short. I bought an AT&T S3 full price, off contract, in the States if that matters. (I live in Canada.) Five months ago it bit the dust out of nowhere in a most peculiar way - it does not power on regularly with only the battery (I have tried a friend's working battery) nor charge with USB inserted, but does power into download mode when a 301K jig is inserted with only the battery, and it lets me fully flash an ODIN image. When ODIN autoreboots the device, it boots to the first boot logo (no animation or sound) and does not proceed. Pulling the battery gets us back to square one, device does not boot at all.
Let me be clear before I proceed: this phone has been babied, never come into contact with any water of any form, and never dropped. The liquid damage indicators are, of course, white as ghosts.
So what to do? Call Samsung and send in for repair. Their findings?
Code:
Original Problem:
INSTALLATION - POWER - WILL NOT POWER UP
Problem found:
CORROSION, LIQUID DAMAGE
Solution:
BER
BER means beyond economic repair, apparently. So, I call them back, insist they fix their damn products, speak with a manager
(who describes that the damage as corrosion to the menu/back key connector, she specifically described "14 vertical components and they look very rusted, yeah that looks damaged to me")
I insist they are wrong, the whole nine yards, etc, they clear the BER flag and let me send it in again.
...and they say it's liquid damaged AGAIN. Exact same story. Just now apparently it magically migrated to a new location. The tech stuck a red chevron on my board over the PM8921 IC, which would make sense if the device won't power on I suppose, but there's no corrosion to be found anywhere.
This is where I am right now. I'm pretty furious at Samsung and I cannot go to my carrier because I was an idiot and bought the device full price.
Here are pics of my device to prove what BS Samsung is trying to pull here. Sorry for bad quality, the Nexus 4 is horrible at macro focus.:

All looks good here (menu/back key connection):

Does anybody know who I can complain to in order to actually get my phone fixed under warranty? It has warranty until December (which is useless by the looks of it) Small claims court? Better Business Bureau?
Any help is appreciated. Thanks in advance.
Update: Called Samsung again today (got to Tier 1 right away), and after politely asking to speak with Tier 2 (and being put on hold for nearly a half hour...), I asked to speak with Executive Customer Support. This was the department I ended up with last time that was actually able to resolve issues instead of repeating themselves over and over. I was informed that they are only in on weekdays.
Looks like I'll be calling back on Monday...
Another update: Finally got through to Executive Customer Relations, who promised me a call back to go over the details of the case. I will be giving them links to these photos to compare what they claim versus what I see, so hopefully we get somewhere.
Was your phone used or new?
New, sealed.
I'm writing this as my unofficial first post here at XDA, as a current M9 user who's faced a popular issue with this device, plus a new, hopefully worthless issue aswell.
I've had an M7 for roughly two years. Used to think it was the best smartphone I've ever held. I found it incredibly good looking and the performance was(is) amazing. Never had a problem I couldn't solve by reading threads here at XDA about issues, typically software related, that other people shared. The only hardware issue that really bugged me was the pink tint in the camera, and even that got fixed in the end.
Following this, I'm really upset that I've now sent my 4 months old M9 for repair, again, in less than a month.
First, I had the vibration issue many other users faced. With a turnaround window of about 3 weeks, I got the same device back, with vibration properly working. This was about a week ago.
Yesterday, I had to take it back to the carrier store(Vodafone Portugal) because the power button ceased function. I have no idea how that happens and I hope it's something minimal, because truly, I don't understand how a premium phone like this ends up with such bogus issues.
Here's to hoping the turnaround window is smaller this time, seeing as the problem seems tiny this time around.
Hi there!
If you are in Portugal I recommend heading to tecmagnet.com. They have this section specifically for repair services (only electronic devices) and there are some there who repair a lot of HTC's phones

Hey guys. I bought my Z5P on dec 23. It had a broken screen, i replaced the screen early in January and everything was great.
Then in early February the screen would get vertical lines at times, suddenly appearing then randomly disappear after 10 seconds all the way up to 8 hours later. The screen would randomly become quite warm/hot a couple of millimeters above the on screen buttons, aswell as heat up the entire phone randomly while in standby for some reason.
On Feb. 10 the lines came to stay, they are now constantly there in darker images as well as constantly sometimes in all scenarios. The 3.5mm port is also buggy and don't work if i move (I know about the software issue, this is hardware related).
So, i'm faced with exchanging the screen again for 60-70$ or change screen and frame in one for 90$ as well as the 3.5mm. Should i just throw in a new screen or will the problems likely reappear?
I did the previous swap myself, and cant find anything wrong with the install. The screen may sit a tad bit deeper in the frame now, the plastic edges rise above the screen on both sides. Screen appears to be OEM, same quality as original in all aspects until it failed. The phone has obviously been tampered with before i bought it, its missing 1 plastic cover over the charging port so i propped that up with a plastic piece as well.
Anyone with any experience with these kinds of problems on this or other Sony phones would be greatly appreciated!
Thanks!
For some reason i clicked the wrong button on log in and posted with my google user.
Here is a image showing my problem on a different phone.

since you bought it with broken screen, the scientific question for you to be asked back then was
1. how did it got broken? dropped from height ? heavy object dropped on it.... in either case....
2. what else may have had got damaged inside?
My sister had SAMSUNG s4 and she dropped it , it hit on the floor and lines/bar started appearing after a while! later the screen went blank... we replaced the screen and it worked only few hours and went blank again! ,,, finally the technician told us that processor or graphic chip may also got damaged or affected so replacing chip is not possible unless you change the mother board! (which will cost $400 with labour charges )
long story short! we gave up on that phone! when the market is saturated with variety of good hardware on competitive prices...
Just thought I'd share with you all pictures of my wife's Note 4 with a swollen 3rd party battery.
Before I begin, I personally never had problems with the few Anker brand products I've used. As such, when shopping around for a replacement battery for her, I opted for Anker..
Early last week, she told me her phone is falling apart. The screen is separating from the body. I reviewed a few teardown videos on YouTube and, before I had an opportunity for a closer inspection of the unit, I came to the conclusion that the separation occurred due to one of two things; 1) her overcharging caused the battery to swell, or 2) the heat from overcharging has caused the adhesive to give way.
Today, I had her remove the battery cover and, low and behold, the battery is swollen pretty severe.
I told her to not charge it unless it gets below 50% and not let it go over 50% until we get her a new battery.
Do you all think it may be possible to insert a new strip of adhesive without tearing it down?

I wouldn't risk using that battery. You should just safely dispose it off. It could explode or catch fire imho
