Before anyone go crazy, it's most likely my fault. Since the battery is superglued to the phone I had to bend it pretty hard when I replaced the screen. And it was probably damaged
Anyway 6 month later my battery expanded and broke the glass back. There is a very visible bulge on the back (~1/16" thick), on a flat surface the phone wobble. I don't know when or how it happened, at some point I got the phone out of my pocket and it was broke.
I have a strong suspicion it happened while using a 2.4A/12V car charger at -25°C.
My real question (TL;DR) : Is there a risk using a 2.4A/12V car charger ? (my previous one was a 1A and it was barely charging the phone)
Doesnt matter what the current output of the charger is. The device has current limiting technology. It will max out at 1A so if your using a 2A charger your fine.
Also the car puts out 12VDC but it gets stepped down to 5V at the micro usb port. Thats the industry standard.
Now when you bent your battery you started the process of damaging it. Li-Ion batteries have a very thin sheet with paste on it and that is wound up with many layers. By bending it you probably flexed the thin sheet and that soft spot eventually broke and when that happens a chemical process begins to break down the battery. The bulging you are seeing is a buildup of gasses inside the sealed battery its self. When a battery begins to bulge its going bad. This can also happen prematurely if you expose it to over heating repeatedly OR for a long period of time, OR if you allow the battery voltage to drop to low for to long. Li-Ion just doesnt like heat or low voltage.
I concur with IAmSixNine you need to either replace the battery or get a new phone. And be sure to dispose of it properly. I had the same problem years and years ago with an old HTC touch diamond. The battery started bulging and I eventually had to remove the cover and use tape to hold it in. After a couple weeks it burst and it wasn't a pretty site... Pretty dangerous carrying around a battery that could explode in your pocket at any time.

Thanks, good to know that the charger can't damage the battery, I have purchased a new battery lets just hope this one does not explode in the mean time
Ive replaced the battery, the first charge took 8hour to 90% and now it wont charger over 50% is there a way to reset the battery limit ?
Sent from my Nexus 4 using Tapatalk
let it cycle a few times to correct the battery information.
That means let it die down completely, then charge it completely. Do that a few times and if it still causing issues its possibly a bad battery.
I think I also have a faulty charging port, only the wireless charging is working now, when I plug into any usb there is the lightning icon but it says not charging. I'll switch the daughter board with the one from my other broken nexus 4 to see if it fix the issue.
As much as I like my Nexus 4, I'm not impressed by reliability. In under 2 year, I've had 2 broken screen, 1 broken bake cover, 1 expanded battery and now possibly the charging port. My nexus S and Galaxy nexus with a million drop each are still working as new
One of my friends got one and broke his before the 2 month mark. He was ribbing me about getting a case for it and making it more bulky. I was not the better man...

I bought an extra battery and charger on my Evo and noticed that recently, my Evo battery is now performing WORSE than the cheap Chinese generic knockoff battery.
The Chinese one use to run about 1 - 1.5days but now runs over 2 days (thanks to new kernel by HTC).
However, the red battery which used to give me 2 - 2.5 days run time (on older kernel), now only runs for 12hrs.
Any ideas?
Are you charging the stock red battery with the Chinese charger? You shouldnt do that. But as far as the chinese batteries, it doesn matter how you charge them.
Go into a battery program, spareparts or batteryinfo widget, and see if they are charging to the same voltage. I have several htc batteries with all about the same use, I have 2 of them that are almost a 100mv lower then the others so I "top" them off by unplugging and replugging them in a few times while charging.

Where did you get this info? The external chinese chargers are a slower, less powerful charge. I get more juice out of the battery than charging it in the phone, due to the quick 10% drop. Everything I have ever read says that slower charging is better for the battery in the long run. Please link where you got this from.
I have 2 batteries, the red one, and one that came with my Hero. I charge them in the cheap charger and rarely actually charge the phone.
I see no difference in battery life.
the whole quick charge tech is no good, my $4 chinese charger (no quick charge crap) works way better then charging in phone, i had an older laptop, one of the first to claim quick charge, with a battery that was wearing down about maybe 90-60min got an external charger that charges slowly and managed to recondition the already 4yr old battery to run 3hrs but went back to charging on laptop and battery slowly ran down again to about 1hr
On my PHILLIPS ppc6700, I had done this exact thing, with an eBay battery. I noticed NO difference between the two batteries, and I even ran synthetic tests to confirm. I believe I posted those results a LONG time ago on ppcfreaks.
I then bought the Saedo (sp?) 3700 ma/hr piece with the extended battery door and the dock, and that thing kicked ass. I would get like a week with an overclocked proc on fast evdo and a cooked ROM nue2chem I believe, its been a long time.
Then with my 6800 things got really bad. I went through maybe 6 phones from dead charging ports. I honestly felt like at least half of those failures (which were all replaced basically no questions asked, besides one) were due to gas-station car charges and laptop cords. Such a nightmare.
My guess is that most mini usb port failures from back then were due to the actual design standard being so loose that knock off, low cost manufacturers without precise and developed manufacturing techniques were marketing chargers that would arc my usb port to death over like a 1 hr drive. This is of course a guess. When Sprint questioned my one replacement I simply had the guy who had my phone taken apart bust out his magnifying glass and we could both clearly see burnt leads on the PCB. Couldn't see with the naked eye.
Also that older standard was thicker, and it thus exerted a little more tensional force on the port/PCB, which could have created the same effect.
Flash forward to my Evo: the new micro usb standard is FAR superior to the previous. No issues so far. Other chargers seem to work fine, without issue. You bet I was suspicious though, and I did all my checking within the return period. They DON'T have more Evos, so if you think that 8 dollars saved on a charger or something is worth it, Kool. Just as long as everyone knows the risks that have historically been associated with cheap chargers. At least anecdotally.
I would possibly consider some extended evo batter package if it was cool looking. Clear backed and extended maybe? With a small led batter level indicator on the battery itself, shining through the back with a small integrated button press.

Yes, i never charge from the phone anymore. I just use the phone till it dies and then swap with a fresh ly charged battery. I charge both of them in the cheap charger.
I was thinking that maybe the phone battery recalibration got whacked? Just a guess.
Any battery charges better with a lower amp charge period. I charge my deep cell boat batteries at the beginning of the season on 2 amp trickle charge. I have had them for 10 years now. Way over the life expectancy. I charge my evo batteries on a 400 milli amp wall charger. Way better charge and they charge 100% everytime.

Okay, I'm convinced. I'm slow charging mine in an external charger.

Hi everyone,
First of all, I apologize in advance,
1. Because I know this isn't a tech support forum.
2. Because I don't contribute and help out as much as I should.
Coming here was a last resort, I don't consider myself a noob, but I'm really stuck here.
Please note that I appreciate every single response, and I will donate if anyone can give me a fix.
With that aside, let me get started
__________________________________
Okay so about a week ago, I accidentally bent my charger when it was charging my note.
It didn't charge at all that night
That morning, I blew into the charge port on my note, suspecting that dust may have been the cause.
Somehow, that helped, as my note charged fully that day, in about 2-3 hours
Then I tried charging it the next night.
It charged incredibly slowly, reaching about 70% after 10 hours charge
The next few nights were similar, but reaching no more than 40% charge after 10 hours.
It got progressively worse, it would only charge if I applied pressure to the mini-usb,
I looked around this morning, and stumbled across another guy with the same problem
(see here http://www.galaxynoteforum.net/galaxy-note-help/charging-port-issue/ )
He advised,
"Well I have figured out the issue. If you look into the charging port slot on the phone you will notice a small thin flat piece of metal which inserts into the charger. That was slanted and angled downward which would not let "ANY" charger or docking station charge correctly also causing it to drain the battery. Contacts on this piece and the phone were to close causing a minor contact draining power. I used a precision flathead screw driver and lifted the piece slightly and now works fine"
So I tried that, and it seemed to help, as the note began charging, (extremely slowly, reaching about 30%)
Then I tried pushing that "thin flat piece of metal up even further"
However, I went too far, and I couldn't fit the charger into the charge port.
So I tried pushing it back into the centre but I may have damaged one of the pins in the charge port (inside the phone)
I seen a little spark, and the note turned off.
I tried switching it on, and managed to boot to safe mode (no idea how)
So then I tried charging it, I applied pressure and managed to get it to start charging. (thank god)
This was about 30 mins ago, it looks to be holding the charge at about 20%, but it's not increasing
-----------------------------------------------------
I suspect one of the pins in the note charge port was snapped off.. although I'm not sure.. (it appears to be the one on the right)
1.Does anyone know how many pins there are on the charge port inside the note? (is it 4 or 5?)
2.What should I do?
If I broke a pin, it should not charge at all, right? (but it seems to be charging)
3. Do I need to replace the charge port, if so, how much would it cost?
4. Would I be better off getting a charging station, and charging the battery using that
5. Should I try moving the metal strip again? (inside the charge port of the note)
oops forgot to mention, when the problem started, and the note was slow-charging, an audible buzzing/humming could be heard in the wall outlet
also, I'm using my original samsung usb charger, not a generic one, and I'm charging directly into a wall outlet.
------------------------------------------------------------------
Thank you for taking the time to read this, I really appreciate it, and any advise that you do offer.

Here my tipp: You can go to a service center, maybe they even repair it under warranty. Or you can order a new micro usb port and replace it. Google should help you to find a seller. Depends on whether you feel comfortable enough to replace it yourself or not. Oh one more thing, I would stopp using your Note to avoid any further damage.
Sent from my Galaxy Note running ICS
there are 5 pins on the charger slot, 4 I believe are for data transfer and the 5th being the one that draws power (charges the phone)
Have you tried transferring data from PC to Phone and see how that pans out ?
Its possible to replace the USB port, Ive seen a few threads about this on XDA, A quick search should chuck out some results.
But as mentioned above, Try to claim under warranty first, if you have it, or pay the Service centre to do it if you dont feel confident enough to do it yourself.
I think I recall someone with a similar issue and it cost him / her $60 for USB replacement (convert that in to your currency)
If you have a friend with a Note or a phone that fits the Note's battery you could always charge your battery in that phone and place it into yours until you get it fixed.
IF YOU MUST charge your Note ( you could if you intend to get a new USB slot) I would suggest to charge only via USB - as in charging from your PC / Laptop / TV / PS3 etc. As this will not draw as much current as it would coming directly from the mains supply!
Good luck on getting it fixed, And please keep us posted with the results !

Thanks for the quick reply!
First of all, I can confirm that no pins are broken or bent, everything looks normal, it also seems to be charging better, as I centred the metal strip in the charge port.
As for warranty, well I didn't purchase any extended warranty or insurance, however, the standard warranty lasts 2 years.
Unfortunately
The Repair Warranty Exclusions are as follows: (i) Subject to the inclusions of the applicable manufacturer's warranty, a mobile that has broken down or is damaged as a result of: (a) abuse or tampering, (b) electrical damage, moisture, dampness, oxidation, corrosion or food, dirt or liquid ingress (c) accident, neglect, impact, actual or attempted theft, fire, power outages or surges, or incorrect voltage, (d) transportation or packaging (e) removable batteries or damage caused by battery leakage
Basically, the only thing that I'm covered for is "handset breakdown"
My phone is in perfect condition, and no pins are broken or bent (as discovered on closer inspection)
So do you class charging issues as "handset breakdown" or not?
I may purchase a new charger, just in case the issue is with the charger, and not the phone,
What d'ya think?
Thanks again for the quick replies azzledazzle & nipuna, I didn't notice them until now,
Yeah I'm 90% there's no damage to the pins on the charge port, and it seems to be charging now, slowly at least,
I've centered the metal strip as best as I can, (inside the charge port)
I'll leave it to charge now for a while, as I'm not sure if it's fixed or not
Then I'll try another charger if it doesn't work
If all else fails, I'll try getting it repaired under warranty
(although that's more of a last resort, as it will take a few weeks to get my phone back)
does anyone know if the standard galaxy s2 charger will work on the note?
I don't have it on me now, although I could borrow it from a friend
I know its an official samsung charger, although not sure if it's the usb or the other kind.
I'll let it charge for a while, then I'll try transferring data from the laptop, to make sure the pins are fine,
thanks for all your help everyone,
1st of all: if you go poking around in the usb port with a metal screwdriver, take out the battery first. Not only will it avoid shortcutting and maybe blow a fuse inside the phone, but it will also protect you from an exploding battery when shortcutted !
S2 charger will work

Yesterday I used my N7 while running errands & it was parked in the long neck windshield mount I have for it. This is the first time I've done this. I work third shift and it's usually night or early morning (and cool) when I'm driving with the tablet. Yesterday it was hot and the sun was shining. I didn't leave it in the car but it got hot riding around. I kept it plugged into my car charger the entire time (2 amp charger that fast charges). It stayed charged up most of the day but at some point it stopped charging. I noticed when I got home and the charging animation had stopped.
I took it in & plugged it into the wall A/C charger but it still did not report as charging. I just thought the battery was hot from being in the sun all day & had tripped some thermal sensor that prevented charge. I kept it on & plugged in thinking it would start back up when the battery cooled off. Nope.
The tablet is @ 6% now. I is off completely now and I don't have enough charge left to do a nandroid. I've tried all kinds of combinations of chargers and cables but it refuses to charge.
Did the heat kill the battery or some of the circuitry?
Is there any way to back this N7 up?
I'm planning on getting a new one when the new models come out anyway but I'd at least like to get a backup off of this one...
Edit: I updated my sig before submitting this post but it's not showing up yet.
I'm running Trinity Kernel & RasbeanJelly. Both are up to date.
Update: For anyone interested, I found & fixed the problem. I took the back off & was looking around for anything obvious. I knew the problem had to be either the battery or the usb port (or the electronics for either one). The battery is pretty much self contained so not much I could do there. The usb port is screwed down under the speakers and there is a flat ribbon cable that runs from it up to the logic board. The connector on the board is covered by a piece of black electrical tape type material. That is where the problem was.
There is no locking mechanism for keeping the ribbon cable seated in the connector. It is only held in place by the tape. When my Nexus got hot, the adhesive on the tape failed and the ribbon cable must have moved just enough to disconnect it. Thus preventing power getting from the port to the logic board and battery.
I reconnected the cable & reapplied the tape.
Problem solved!
On a side note, this week without my Nexus made me realize just how much I love this tablet. I have a Nook color running CM7 and an HP Touchpad running CM9 that I used as backups but the Nook was way too slow and the Touchpad was too big to be convenient. I can't wait for the new version...

I suggest putting some hot glue or 2 part apoxy on that ribbon cable to keep it from happening again.

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
Could my work on my XT1575 cause the phone to charge very slowly? As long as I was using a good QC3 charger and a QC3-certified micro USB cable my MXPE phone charged fast. I have TWO working XT1575s. When plugged into the same charger with the same USB cable they both showed "Turbocharging" and both charged quickly.
Last week I replaced the back of one of the phones. -- exchanging the original back with an ebony wooden back. I had problems getting the ebony back to stay completely adhered so I installed it, removed it, installed it again with better adhesive. looks fine now.
Now, the back is securely in place BUT THE PHONE WON'T CHARGE FAST ANYMORE. Could I have damaged something in the phone while doing all that heating during the back replacement? I use a heat gun, always on the low setting, but I for the last installation I moved the heat pretty slowly around the back to increase the heat and hopefully improve the adhesion.
Everything about the phone works perfectly, both hardware and software. When I plug in a charging cable is shows "Turbocharging" but the charge time estimated by the phone is 7 or 8 or even 9 hours. That's about how long it takes too. And the phone won't charge past about 90%.
I've already replaced the battery. I have no idea how to further diagnose the problem. Have I effectively destroyed my phone while putting on a prettier back (to summarize how stupid I'd feel)?

Either you have a cheap low quality battery or you probably burnt it up with the heat gun. The NFC pad is on top of the battery if that still works then I highly doubt anything else was damaged but I could be wrong. Worse case scenario you desoldered something on the motherboard but I doubt it. First check the wattage on your wall charger if it says 5 volts and 1 Amp then that's your issue. Most wall chargers or USB ports I use have to be at least 5 volts and 2 amps or it will not charge and it'll actually get stuck at 90% like in your case because the charge rate slows down after 80% I believe and a crap wall charger won't have enough power to charge the phone like a high quality OEM wall charger would.
