Don't worry that is a common problem among many android devices.It will eventually cool down.Charging also leads to the phone getting warm or even hot,but it will cool down eventually.
Since USB is not an AC source of power,there will be a very slow charging rate.or it will not charge at all.it happens with me too.

Try not to use your phone while charging. Not only do you affect it's battery health it also gets really hot
Nexus 4 has been reported to get hot easily so try not to use it while charging.
Also, try undervolting to see if that helps your problem. Im sure ParanoidAndroid comes with a custom ROM and root
and you will be able to undervolt
Good luck

Also another thing when I charge, using usb or wireless I make sure to take my case off, I am using the seidio case with is rubber and has a hard plastic wrap around and find that the rubber does not allow the phone to breath when it is charging making it extra hot.

I disagree. I use an X-line hard rubber case and always have the case on when charging. My phone "never" gets hot. It always stays at its usual temperature. And I don't live in a place where the weather is too cold.

Woke up to a [possibly] bricked Atrix :(

Yup. Left phone on charger overnight - woke up and the camera was flashing every 2 seconds. That's all it will do. Whether it's hooked up, unhooked. As long as the battery's in that's what it does. No rom changes in over 2 weeks. No damage of any sort.... no recovery or anything
Well you can probably do a warranty exchange.
I voided my warranty and your mum.
I had something similar with my nexus one. Except it wasnt the camera but the trackball... changing kernels around seem to help a bit but eventually i took it for water damage. Take the battery out and let it dry off for a day or two. You can also try to pry it open and have your hand at any corrosion if you find any. However i wouldnt recommend that unless you know what yer doing.

He said it was left on the charger, not fell in water.
I'd crap my pants if this happened to me.

I realize that but like i said i had the same experience and my phone didnt get noticably wet at any time could have been a single drop of water and corrosion takes a while to build up.
Still...
Im wondering if you used your original charger when this happend because i can personally say ive seen my atrix behaving strange when connected to some cheap random charger (touch screen not working for example). Didnt believe it could cause permenant damage though.

It was hooked up with a Blackberry charger, actually.
Still acts the same.
Check the charger to see if its power ratings are different than your otiginal one.
Also... does the device boot up in any way or is the screen simply black and the flash flickering no matter what?

Looking at it today, I noticed that the charger port (or inlet if you will) is very structurally loose. The voltage on the blackberry charger is about 3/5 that of the stock Atrix charger, if memory serves me - somebody at work switched out the chargers the day after I got the phone. It took a good 6 hours to charge...
ATT said that it would be full cost of phone, because it's personal damage.
I'm looking into the Mi-One.
EDIT: No, the screen will not even begin to come on. Camera flashing is the only indicator of any power. Used an external battery charger, and two different batteries.
The MI-One looks sweet!!!!

Moto will probably either fix it or send you another phone. I know people who bricked from trying to downgrade and they got another phone. I'm sure you could too. I would try that before you buy another phone.
ETA: Now that I think about it not being able to put the rom back to stock would probably be an issue if they can get it to turn on but if they can't they might replace it.

I also think you should bring it up with motorola. Waking up to find your phone bricked is hardly what id call personal damage. You also shouldn't bring up the charger issue. And as for the usb port i'd say it would take too much effort to discern the connection with that and the phone acting as it is, and im sure they would rather just send a replacement unit.
A usb port malfunctioning is hardly an account for personal damage. The usual case is they simply stop working, but definitely not brick your entire phone.

Can I charge in a case?

What the title says, or do I need to take it out each time to charge? It's a TPU case.
Wireless charging, you mean? Not usually unless it's super thick.
I charge my N4 in a case but I use a wire so lol
No, I mean wired charging. Just dunno whether it could get too warm in a TPU case? Or can I charge with it on.
If your phone gets abnormally hot for some reason, you may want to be careful. My phone used to get kind of warm, but undervolting fixed that.
Li-po batteries are susceptible to damage above 60°C.
I'm not sure it really matters if you charge inside a case.
I can charge just my N4 just fine in my i-Blason S-case. At first the plug came out with just a little push but now it has normal strength. It just had to "break in".

[SOLVED] Did I cook my battery?

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.

Anyone used wireless charging?

Has anyone with the verizon model used the wireless charging? I'm just curious how well it works. I have never had a phone that was able to do that so I have no gauge on how well the technology works.
Thanks
I got the official LG WCP-300 Qi wireless charger along with my Verizon G2 on release and it works well. The charging coils are located under the camera towards the lower half of the phone and you don't need you to find the 'sweet spot' for it to detect the charging pad. It obviously doesn't charge as quickly as plugging into the wall charger but it charges my phone from about 20% to full within 5 hours. I have the charging pad always plugged in on my nightstand next to my bed and it doesn't go anywhere. Hope this answers your question!
Edit: There's an LED on the front of the pad that glows a soft amber when not charging and turns to a bright blinking green during use. I just turn the LED away from my head at night and it doesn't bother me at all.
Yeah that helps. Does it work with a case on it? I'm thinking about just getting one that I can use at work. Leave it on my desk and just charge it as needed. It may may make things easier than having to worry about plugging it in off and on throughout the day. I probably don't need one really because the battery does last me all day, but I tend to get anxiety once the battery hits the 50% mark.
It works just fine with my LG QuickWindow case. I initially bought the charging pad for the same purpose that you want to do with it but after using it, I didn't think it would be worth it to leave at my desk at work simply due to the slower charging vs USB. If I left my phone on the pad every now and then it would only charge a few percent each time.
I'm using the anker one and it works very well with cases on. Doesn't get hot either
I'm using it with the stock gel case with no issues.

Is it possible to get the international G2 wireless charging ?
Sent from my LG-D802 using XDA Premium 4 mobile app
I got the Tylt Vu. It works great. It sits by my bedside. Every morning my phone is at 100%.
I have the Incipio Feather case, although I'm not using it currently, but I tried it on, and put it on the Tylt Vu, and it started charging with the case on.
I have a Nokia charger with the Diztronic case.. works fine.
I had the Samsung charger tray for the Galaxy S4, they mostly worked, but you had to scoot them up pretty high in the tray to get the thing aligned.. sent them back.
Nokia has 3 coils so it kinda self aligns.
So has anyone used the wireless charging with a thicker case? I'm going to be getting a G2, but the only thing that worries me is the lack of bezel. I'm paranoid that I'm going to drop it and want to get a thicker case.
I use it daily. Nokia fatboy. charge it over night every night through my incipio feather case. charged through the Verizon TPU as well.

[Q] Battery expanded and broke glass back

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 ?

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...
