Normal operating temperatures?

This phone gets hot! I'm at 103°F right now while charging with lowest screen brightness and just going thru xda and the web. Should I worry?

That's about right 40 degree Celsius ..... I don't think you need to worry

Really? It feels so dangerous though..

Phones always seem to get hotter while charging anyway

That's roughly 39-40C which is normal for a smartphone under constant usage and/or load. My Galaxy Nexus was around 38-39C whenever I used it for extended periods, that's nothing to be worried about.

My single core 1ghz galaxy s is AF 40° charging, browsing web and on xda. Your fine.

It probably just feels really hot because of the glass back, but as everyone has said, that's not too hot at all, pretty normal, especially when charging.

Thanks guys. So what temperatures should I look out for?

Don't worry about it, OP. The phone will throttle itself to lower the temp if it gets too hot. In an extreme situation it will shut down. The engineers took care of this. It'll be OK.
You remind me of first time parents who boil everything before the baby can touch it. By kid number 2, they just pick the pacifier up off of the ground, wipe it off and pop it in the kid's mouth.

I never use my devices while charging but light use is pk I guess. Gaming and stiff while charging though gets things really how very fast..

This phone does get hotter than the Galaxy Nexus, but it's nothing compared my HTC Sensation. The hottest phone I have ever lay my hands on.
Btw, anyone know any good apps to record the temperatures?

Hmm idk about that. My Sensation did get crazy hot when I used the Chichitec battery in it but when I switched to the Anker battery I rarely noticed any heat anymore. But this N4 seems to be up there, maybe a little more than I ever felt my Sensation.

My n4 died while I was sleeping!

Yep, I woke up to a completely unresponsive nexus 4. Tried charging it and nothing happens. Also tried holding the power button, using the bootloader, but nothing will make this phone turn on.
Noticed just a little while ago that the lense for the camera and flash have collected moisture inside. Could running the phone on battery until it ran out of power create moisture in the phone?
Sounds kinda crazy, but it's the only thing I can think of. There is no other reason why the phone would have moisture on the inside. It wasn't raining, nothing in my apartment is wet, and neither is the outside of the phone.
Was using stock rooted with matrix 2.0 kernel.
Update:
The moisture inside dried out so I tried powering the phone on and again it did nothing. Then I plugged it in and the led indicator turned solid red.
I didn't know what that meant so I called tech support and that guy was even more clueless than I was. He hasn't even heard of the blinking red led that some people from this forum got after running antutu overclocked, but at least they can return to stock and relock the bootloader.
He said I could get it replaced, but idk if they're gonna give me grief over being unlocked and rooted.
Update 2:
Now the red led no longer lights up when charging. The phone powers on and everything functions except the screen. Even the buzzing from the ear speaker is there like it was when the screen functioned.
I powered it down now in hope that it will work later tonight.

Does anyone have an idea of what could have caused this?

Oh man sorry to hear and see that. Maybe something burnt out inside and the smoke couldn't escape causing condensation? I dunno, but hope it gets sorted out..

There is a similar problem with nexus 7 running android 4.2 .. What that required for correction was holding the power button for 30 or more seconds .. I repeat 30 or more seconds and not mere 5 or 10 seconds . that trick worked for me .. Just give it a try
Sent from my Nexus 7 using xda app-developers app

I already tried that. For now I think I'll have to just let it dry.
I would still like to know why only the inside of the phone has moisture and nothing else.

Thanks for the wishful thinking, but I don't know how I'm gonna get it replaced if I can't return to stock and lock the bootloader.

Sent from my Nexus 4 using xda app-developers app

True. I say you put it in an airtight container with some dessicant and see if that helps the moisture. If not, give it a shot and send it back. Sorry to see that happened to a brand new phone.

I don't think so, it's just me and my girlfriend here and we were both sleeping. I don't think that would harm the phone either. Anyway, the outside of the phone was completely dry the whole time. No other areas are affected.
The phone I'm using now is an lg thrill and it's been through rain, snow, left outside and it still works. I don't understand why the n4 would do this just by sitting next to my bed.

Santa Claus came early
In all seriousness, did you take it in a moist room like your bathroom? Or outside on a rainy day?

what about the bag o' rice trick?

Humidifier running? Was it on the night stand maybe next to a cold drink that could've had some condensation? Was the room exceptionally cold (maybe that combined with the warmth of the phone caused the condensation?)?
Really weird. Hope you get it sorted. Chances are though, if it shut off because of the condensation, it probably burnt something out. Generally, if it's off and gets wet, you have a better chance of it surviving than when it gets wet and shuts off.

Could it be a battery leak?

Nope, it was dry in my pocket all day. I even got good battery life at
4hr screen on and ~14hr total. I left it unplugged next to my bed with nothing next to it to see how much longer it would last.

It was on the night stand, but nothing liquid was nearby. And my room is always at a constant temperature. Neve had any problems b4 with condensation.
It did have a low battery when I went to sleep and I left it to see what kind of battery drain it would have by morning. I thought only the battery was dead at first, but it's been on the charger now for about 15 min now with the solid red led.

It would be my guess too that the battery is leaking and just RMA it. As it doesn't power up they will never know you rooted it and they will most likely just trash it.

Mine charges faster with the cord that comes with the phone then with a universal cord tbh. Maybe its is somehowe defective.

I had that happen to an older phone that I had, cord just got wore out or something. But I haven't had any problems with the one on my nexus 4, I am sure that you can pick up a very cheap one almost anywhere though, even gas stations have them I think

Exhaust

Guyz is there any exhaust hole for heat emission in n4.
Sent from my Nexus 4 using xda app-developers app

I think the speakers and/or the camera and flash serves as the exhaust.

the glass back is meant to transfer heat out(thats why it gets warm with use, thats why its glass).

I notice that compared to other devices I've had the N4 gets very hot..

it actually doesnt get as hot as most devices. but you can feel the heat more, because of the glass back. if it was plastic/metal, you wouldnt feel as much heat. it just means that the glass back is doing its job right. my galaxy nexus and nexus 7 get much warmer, but it isnt felt as much because the backs are plastic.

Of all phones in household between original nexus s, sensation, hd2, nexus 1, one x+ and n4, nothing comes close to beloved n4 . Few times I'd to end call as its fricking hot in ears and hand. Good thing at least keeping us warm in UK's summer cold

Far as everyone mentioning the glass back, I thought glass was an insulator, not a conductor (something like aluminum or such would dispel heat, glass wouldn't necessarily, as it's an insulator).

Glass is a terrible thermal insulator. It is however a great electrical insulator! Ha

You mean aside from your USB port, headphone jack, edges around power and volume button, around the LED light, and speaker hole? Honestly I think people are making a mountain of a mole hill out of this, has anyone actually reported a Nexus 4 exploding in their pockets? (from overheating that is).
In any case if you're curious about the innards, check out this tear down of a Nexus 4.

I actually used to have a sensation and it didn't get nearly as hot as this phone does. Neither did my G1, My Touch, Vibrant, S2, or my wife's note 2...
Not a big deal but I could use the N4 as a heat source to keep warm in the cold... If it wasn't 100 degrees out that is

On my Gnex, you can feel the heat on the chrome part of the camera, which gets hot to the point that it feels like you'd get a little burn

No. LG suggests you drill several holes to prevent overheating as it is a VERY big issue for nexus owners. I attached a CPU fan to mine and it rarely hits 200°F anymore!

Nexus 4 with a removable back for battery swapping

Nexus 4 is such a well liked device. You guys think there will ever exist a back cover for the nexus 4, one that replaces the current glass back? However it'll be fixed to the phone just like the current glass back, but with a removable latch to exchange battery. Just wondering.

The battery is not hot swappable. There's a ribbon connected to the battery.
