[Q] unprovoked(seemingly) reboots?

I was just wondering if anyone else is experiencing frequent reboots? I am averaging about one a day with really light use(under one hour screen on time). It sometimes freezes at the unlock screen just after the power button is pressed to wake it up after being idle for a while. Other times it will reboot while its just sitting there. My phone is currently on stock ROM and is not rooted.

I did every day and it also got very warm whilst supposedly idle. I got a replacement and have had just 1 reboot in just over a week and it runs cooler too.
I suggest you get it replaced.
Ps. Do you have poor battery life too because it's a lot better with my new phone.

So your replacement "only" rebooted once in a week? Correct me if i'm wrong, but from my understanding, a phone is NEVER supposed to reboot for no reason.

Correct. But I'd consider that acceptable considering it has no other hardware flaws and put it down to buggy software or a rogue app. If it's an isolated reboot then I'm happy, a reboot every day certainly points to a hardware issue and not acceptable.

To me it's unacceptable, as it obviously shouldn't do this and the device seems to be defective if it just does that. Also, there are other hardware flaws, for example that the device gets so hot that it needs to throttle the performance after ~5 mins of work and has to completely shut down after ~10 minutes.

That is not a flaw, the S4 Pro can't disperse heat efficiently in a small device. Not to mention that even throttled, it's probably still the strongest chipset in terms of brute power.

I'm just realistic when it comes to tech. If my only issue is 1 isolated reboot (which it is at the moment) then I'm happy. Don't think I've ever owned anything with a chip that hasn't at least restarted/frozen once.
Sure the phone gets warm under heavy use but I haven't noticed any slowdown in real use so all good. PS My previous did stutter when hot, unlike this one, so I'm certain that was faulty.

That's not correct. There are other phones with exactly the same CPU, and none of them throttle. Only Nexus 4 does.

A benchmark that is fireing up ~100% of the core is not "normal work"
Linpack tests on my CPU bring it to it's knees' but it will never crash under normal circumstances.

I don't really give a sh** what you consider normal work. I've never used that term.
When there's a game that needs the full performance of an S4 pro and the N4 can't deliver it, it won't run. The N4 is the only device that cannot run it's max stated clock frequency.

Then don't buy it? Get the GS3 then. (which btw throttles as well)
I'll wait for some custom kernels and updates to come out. This is brand new silicone.

I think I'm mostly in denial at the moment. I really want this phone to be awesome, however I had my first random reboot about 15 minutes after I got it on the 16th of November. Battery life has been quite horrible most of the time due to the "msm_hsic_host wakelock" issue. I have never had a defective phone and I wasn't ready for a "nexus" to be one. Yes I know it can and does happen. I keep telling my self "4.2.2 will fix all the things".

Actually it probably will...
Do you happen to have a widget that is polling your location? I had HD Widgets installed, with my GPS off it kept rebooting my phone... Now it seems a-ok! This issue has been brought to Google's attention and I think they're working on it.
I don't have the msm_hsic wakelock anymore... Solved that with Franco's kernel and it really improved my battery life.
Hopefully this helps!

I don't, I am running minimal installed apps :-/ . I also have the buzz in the ear piece while on and off calls. It's time to RMA I guess.

I bit the bullet and ordered a new one :-/ The rep I got was awesome and the overall experience was good. Unfortunately I was made aware that a replacement could be 2 weeks away. Today my phone was off charger for 4 hours in good reception. Screen on time less than 10 mins, sleep time was just over and hour and I have 48% battery left. blah.

Phone gets ridiculously hot on 3G

Who else has this problem
The phone gets hot not warm not pleasant talking on it
Long calls are just not possible
Such a shame for a wonderful product
Its 2 days old

My phone usually gets hot when I'm using 3g but don't get more than 2 bars of signal, try switching to 2g if you know that you're in a place where you won't get a good connection. Or even better, when you're talking, you might as well just turn mobile data off

op.. its supposed to get hot. that's why it has a glass back, to cool off quicker. thats why you feel the heat. if you are worried about heat, dont buy a quad core device. buy a dumb phone and itll remain cool.

but that is not a problem with s4 or note 2 ??
so that doesnt justify

its not a problem with the n4 either. the problem is all in your head. again, it has a glass back to transfer the heat out of the phone quicker. because its glass, you will feel it more. s4 and the note 2 have plastic backs, so you feel it less.

besides op, what temperature is it reaching that you are complaining about, how it feels isnt an accurate temperature reading.

Guys stop embarrassing me
Actually I'm not comparing about heat on the back that's tolerable but its get way too got near the earpiece so that's why I'm complaining
I notice it a lot when I get a call in between my 3G usage

way too hot is what temperature(cpu temp)? im not trying to embarrass you, im trying to let you know that its normal, but you refuse to accept it. so, give more detail, what temp is your phone reaching? hot isnt an answer, hot and feel are relative terms.

The s4 does get hot too, I just had it.
But on the bright side, the nexus 4 is cozy in the winter

there are a few out there, i use the trinity kernel toolbox app. just search cpu temp in the play store. for battery, 60C is the safety temp. for cpu, 95C or 100C is the safety temp. the cpu os near the top of the phone, thats why it feels hot near the earpiece. its normal for the phones cpu temp to shoot up while the cpu is being used. when the screen goes off, itll cool down quickly.

im using trinity kernel now and have installed the toolbox and it shoe 1026 hz clock ??
why is it undervolted ?

Thats not undervolted, and I suggest you dont touch voltages atm and if you do make sure "set on boot" isnt checked.
That speed is just set lower, not sure if that kernel does that for you but you can set that higher if you wish.

all right ....running trinity and its not that hot now

[Q] Is it normal that the phone reaches THIS temperature?!

Hello, I've got my Nexus 4 from this Monday but only yesterday I noticed that it warms up a little too much.
Today I tried a "Classic Stability Test" to see how much the CPU and the battery warms up and after 7-8 minutes... The phone was like lava! Battery was at 50,7 c° and the CPU at 84 c°!
With games like GTA Vice City I got like 46 Battery and 64 CPU, and this should be normal, right?
P.S. I live in Sardinia, 30 Degrees today...

lol well.... is running stability test part of your everyday routine, and something you require to be able to do with your phone? thats like putting a brick on your gas pedal with the car in neutral and getting a little bit worried that the engine temp is rising.
on a more serious note, 64* is fine, more than fine for every day use. games like gta will probably stress your phone as much as anything youd do on a regular basis, even nova 3. mainly because gta optimization sucks, so it still strains your cpu as much as games with better graphics. 84* is getting up there, but lg didnt add a thermal shutdown limit just for the hell of it. you havent hit it, so you havent damaged anything.

In all honesty, I have no idea what the limit is for the battery, I don't even care about this "too hot" nonsense, you should have seen the amount of threads we had on here a few months ago. I do know that 80* is pretty warm for the CPU, but still pretty far from even beginning to damage anything. The thermal shutdown for the CPU is 100*.I don't worry about battery temps, I've left my phones in my car on a hot summer day and it pretty much burned me when I picked it up.... everything was fine. Is that kind of stuff good for it? no. If someone snuck in my car, and brought it into my house and it was completely cooled before I touched it, could I notice that something was funky with my battery? hell no, any difference from any kind of battery abuse on any of my phones has been completely in-perceivable.
Brand new nexus 4 batteries on ebay are really easy to find. And cheap (all things considered). At 40$ a pop, I'll pay that a year and a half later than letting some kind of OCD drive me insane lol, To add fuel to this overheating scare everyone has, I've had my thermal throttle completely disabled since I got my phone, 6 months ago.
Electronics have ALWAYS produced heat, that's how they work. But now, having a quad core 1.5ghz processor in your pocket, that isn't even air cooled, you WILL feel the temperature. That doesn't mean anything is wrong. I dare you to open up your computer right now, flip it off, pull off the heatsink and touch the processor. You will get burned. But that's how it runs, and you never would have known if you didn't feel the heat coming through the case or touched it for yourself.
Sorry for the rant, but yeah, your good and in the clear... long ways to go before you cause damage lol
edit: looks like batteries are closer to 20$ now, they used to be around 40$
edit2: fixed some wording, I sounded a bit like a douche

im glad i dodnt have to reply to this, that someone else answered, lol! but seriously, if the phone overheats, battery or cpu, the phone will turn itself off as a safety, to cool off. anything below the safety temps isnt overheated. when things get pushed, itll heat up, thats jusy how things work. and if the surrounding air temp is warmer, the phone will heat up quicker and warmer.

dont be. there is a lot of misinformed people out there, that just dont know, that publish blogs and posts that end up scaring people for no reason. the thing with the n4 is the "being able to feel the heat", thats what freaks out many. its all because of the glass. my other devices(galaxy nexus and nexus 7) get much warmer than my n4, but you cant feel the heat because of the plastic backs.

Sorry again but this is what i obtained after 20 minutes of Vice City.
OK, Maybe it's the game bad programmed but this can't be "normal".
I've 15 days for ask for a new one, star should i do?
P.s. I just coocked the CPU of my PC like 1 year ago, it works but it got some damages. I really don't want to burn anything else

its hot, but could be normal, especially while playing cpu and gpu intensive games. i play lots on my n7, and i can reach 85C easily when gaming. so its not out of reason. the safety is 100C for cpu, when the device shuts itself down to cool off. out of curiousity, were you plugged in?

No more Overheating Posts

Thread also here: http://rirozizo.blogspot.com/
Hi,
Soon to be RC here, and my first contribution to the nexus 4 world is an attempt to convince you that your nexus 4 isn't overheating.
Some of you replied to my first thread here about what should i worry about in the nexus 4. Some replied that it has a battery drain... that i fixed by removing the google search bar... Others have said that it has overheating issues which some users are scared of.
I'm here to show you why you shouldn't be scared at all.
I was playing Fast And Furious 6: The Game, and 5 minutes later when i ran out of car gas, i closed the game and directly opened Trickster MOD app to see the temperatures of the phone... yes temperatureS.
You'll notice there are two temps in this app: Battery Temp and CPU Temp.
The one you used to check on older devices is Battery Temp, because older devices didn't have CPU Temp sensor.
When i first opened Trickster MOD it showed this:
Battery Temp: 42°C
CPU Temp: 56°C
And then seconds later, the CPU Temp dropped to 49°C and stayed at 49-50°C.
But Battery Temp was decreasing slowly from 42°C to 38°C in about 5 minutes.
Now the reason for the fast CPU Temp drop is that when the CPU is busy, there is so much electricity running through it, it generates heat. But when the CPU is practically resting, the electricity running through it is much less, hence, the Temp drop, which is normal. And also, if you're using a kernel that supports turning off the 3 other CPUs when not in heavy use, then it's better because the less CPU cores active, the less heat.
So the main thing you should be scared of is the Battery Temp... But don't be, because Android is smart:
Android has a built in overheating system which does certain steps to avoid hardware heating damage, if the phone overheats, it takes some steps:
1- If charging, it stops charging to reduce Battery Temp.
2- Reduces CPU speed automatically to make less electrical current run through the CPU, thus reducing CPU Temp.
3- If both of the above failed to get out of the overheat situation, it shuts down the phone.
So if you were playing a big game, and the phone heats up... keep playing that game, android will take care of the rest
OFF TOPIC:
But the question still remains: if I'm charging the phone using the wall charger, and I put it on the wireless charger, will it blow up?

Well, yeah. This is what we have been trying to say since the Nexus 4 came on the market.

"So if you were playing a big game, and the phone overheats... keep playing that game, android will take care of the rest"
the use of the word overheats. its not overheating. its heating up with use, which is the normal way things work. by using overheating, you make it still sound like an issue.

Good topic and solid explenations.
But, Do you think theres a chance the glass back will crack if the phone is at its hottest point(right before it shuts down itself)?
Because I remember that I've read these horror stories before I bought the N4, don't really know if its bad luck or not.

if you drop it in cold water, or stick it into a good freezer at that point, then yes. otherwise, probably not unless it get cooled down extremely fast.

Glass doesn't break/crack because of heat, glass breaks because of the fast temperature variation... in this case 2-4°C max is the variation, so no

Thats true, thanks for clearing it up!

Also android itself doesn't have anything built into it for thermals.
That is done by either a file like thermald or on a hardware level.
It's like saying windows controls the cooling on your pc.
A device example would be the rlod. Lower level stuff. Android isn't even loaded.

you're right, it's not "coded" into android... but so far every android build i've seen has that security system.
but that's not the point, the point of this thread is to stop N4 users from posting "overheating issue" posts, and not worry anymore.

I hear ya. But I am going to rain on your parade. It will never stop.
At best ( which I doubt) they are children that simply don't know much.
But the truth is they are plenty of fools and it will never stop. The level of stupidity I have seen related to this discussion is appalling.
Only way it will stop if it becomes taboo. One thread in general and any new threads about it get closed down and deleted.

Actually it is android that controls temperature throttling. Or to be more precise the android kernel. Which reads the thermald file for it's Max CPU temperature.
There are also hardware cut offs 100°Cpu and 60° battery which will power off the phone.
These temperatures are what I consider overheated. Anything below or throttling is to prevent your device from overheating

Does This Phone Get Hot?

I've read lots of comment about the N4 getting hot under normal use. Is this still the case or has the issue been addressed. I'm seriously considering buying this phone but I don't want a phone that gets hot.

Mine hasn't gotten to hot.
Those reporting this problem are probably a minority of all nexus 4 owners.

Yes the phone does get hot sometimes especially after 10-15 mins of continuously browsing the web on 3G+ or 3G and after 15-20 mins on wifi.. But that's for stock 4.2.2 and 4.3. After undervolting and underclocking the device using custom kernels and ROMs the phone does not get very hot.. It's between 37-40 even after playing games like nova 3 and nfs mw for an hour if you hold the phone with your bare hands and it obviously depends on your configuration.

Thin glassy phone + powerfull cpu = heat Nothing to worry about.

It gets hot, at least on stock firmware, although my definition of hot might be more sensitive than others. I don't know what it would be like talking on the phone for an hour with it getting hot next to your face, although I haven't done that. I have to use custom rom and underclock the cpu a bit, so it's not an really issue anymore. I probably will get flamed for this, but I don't recommend this device to you if you don't like phones getting hot. But I guess lots of these newer flagship phones that has thin plastic casing probably gets hot too.

With normal usage the phone doesn't get too hot or anything. If you are fond of overclocking and disabling thermal throttle you will get pretty high temperature's. Around 70 degrees celcius.

It get's hot as any other phone but because it has got a glass back you feel the heat better.

It didn't feel warm at all after undervolting and limiting heat using Trickster Mod (and has been yundervolted for the past 3 months).
Before that it could sometimes get really hot though.

Yes very hot, don't buy it.

Yes it gets very hot but the thing is you can still use it without getting very hot if you play games then yes it will get hot.

Is your phone undervolted and temprature limited?
My temprature never goes over 40 degrees celsius, and feels rather cold most of the time.
Even with rather intensive games like NFS Most Wanted

This phone will not burn you. There isn't a real reason to consider the heat a problem. The temperature of the phone is regulated by the kernel, if it gets too hot the kernel takes measures to reduce the amount of heat being produced. This is a non issue.
