Something must be terribly wrong. I notice it gets warm slightly when playing around with custom kernels or gaming but not to the level where it is uncomfortable to hold. If you are on stock rom then you should contact google.

I think its because of the radio.. Hot when it isn't on airplane mode. Fine when its off

That kind of heat is an issue. RMA that pronto.

Download system tuner and see what the temperature is when its " too hot"

Mine gots rrally hot when running Angry Birds Star Wars. What about you guys?

I've had two N4's and neither one ever even got warm. At least not noticeable in hand. Even with extended gaming. Agree on the RMA.

[Q] Nexus 4 Heating and Battery Issues

Hello so I bought my N4 on the Dec 3 batch and got it around Feb, the works fine and all but I have 2 main questions
1. The phone gets hot doing simple tasks like browsing the web or watching a youtube video. I am running the CM 10.1 Nightlies and Franco's Kernel r110. Sometimes the phone can get really hot which I then stop using it to prevent any damage. Does this have anything to do with the Custom ROM or kernel because my friend's N4 is stock and unrooted and hes doesn't have any heat issues.
2. The battery on the phone is not what I expected. I hear people who get 4-5 hours on screen time, but I get around 2-2.5. Also I am on a Canadian provider which is Mobilicity if that has anything to do with it. I leave 3G on mostly and just surf the web when the screen is on.
Thanks for any input you guys leave.

If you can take it back to stock and don't root because that is why your friend's N4 is normal besides what more do you want that the N4 doesn't have?

I like the root features and also cm 10.1 if its the ROM that's making it overheat then I know to change or find a better one

Hi,
As always "overheating" is very subjective, it depends on how you feel the heat.
CPU / battery temperature?
In any case there is a protection, a thermal throttling. At certain CPU / battery temperatures the CPU frequence is automatically lowered to help reduce the temperature. In extreme temperature the phone shutdown to avoid damages so no worries.
In 3G the phone heated a little more, no problem here that the phone heats up when you re browsing or you're watching a video on Youtube.
You can try to undervolt a little to see if that helps.
As for battery life it depends on too many factors... CPU settings, screen brightness, signal quality, etc...
Search about your questions in this section or in the General section, there are lots of threads about it.

What temperature does your phone actually get? When running stock it would be impossible to see my phone get other 43c and that was only under very heavy gaming but would usually be at 32-36c ive noticed my phone does get hotter when using mobile data instead of wifi. Now running rasbean with franco m1 and temps abit lower gaming has improved greatly but i dont think there is any difference in battery life compared to stock but your 2-2.5 screen time does seem abit low as i get with just web browsing maybe few youtube vids and few minutes of games around 4 hours screen time but i also envy those who are getting 5+ hours

Forgot to mention thats 4 hours on wifi on mobile internet i should be able 2 get over 3 hours

The phone gets hot very easily in my opinion idk the exact temp but I have the ringke slim on it and its definitely noticeable from the top of the phone to the bottom. Also does my carrier have anything to do with it because brightness on my phone is pretty low and simple stuff tends to drain my battery.

When i was using a case on my phone it was getting hot from top to bottom but now i don't use case it doesn't get as hot and usually stays cooler at bottom half. I have found most accurate way to check your battery temp is by going on call and dialling *#*#4636#*#* and a hidden menu will come up and tap battery information you will see temp, there was an app that had same info but cant remember name so when you think its hot dial that code and let me know what temp it shows. Also are you using mobile internet or wifi when its getting hot?

I think it usually gets hot when using 3G so I'm assuming mobilicity isn't that good for this phone? Also I can clearly tell its the top part that is hot when the case is on
Sent from my Nexus 4 using xda app-developers app

Yep mine also gets noticeably hotter on 3g and yeah it gets hot at the top but after a while will spread to bottom to thats normal. I am currently running rasbean rom with franco milestone 1 and also downloaded pimp my rom from play it has various tweaks and mods so i just flashed battery saving which supposed to help with battery not sure what it does though lol but i managed to get 3 hours 40 mins screen time half of time it was on minimum brightness and other half on 40% was just internet browsing and im sure you will agree that is very good considering i was using 3g the whole time
Sent from my Nexus 4 using xda app-developers app

Just an update you should try undervolting on franco as i have now done it and it definitely helps with heating and i am pretty sure it has vastly improved my battery life if your interested i will post the values i have used which seems to be perfectly stable so far
Sent from my Nexus 4 using xda app-developers app

Yes please, do I need any app for this or can I just do it in the settings?

do you have the franco app? As that was what i used to change my setting if yes just go on frequencies/voltages go down to voltages and change from there i have attached screenshot of my setting and make you do not set voltages on boot as if it is unstable your phone is not going to boot up if that is ticked, you will have to change that everytime you reboot until you are sure its stable then u can set on boot

Do you have a bad signal? Because if so then that will drain your battery a lot more quickly and also possibly make the phone heat up more.

Gs4 hot?

I just got a gs4 and am coming from the gs3. Does this phone run hot normally? Seemed warm on stock and hotter once I tried to install the freegs4 ROM. Even shut down twice.
Edit: flashed a different ROM and kernel and am all good.
Sent from my Nexus 7 using xda app-developers app

Yeah I noticed when flashing certain Roms and setting it up, it gets very hot that it shuts itself off.

Not true on my part. I've flashed stock deodexed MF9 rom with Stock MF9, Agats, and Ktoonz kernel. All resulted in the phone heating up and shutting down on its own.

You might want to take it to sprint in that case, only time it gets semi hot is when im using wifi hotspot and making a call at same time on my part

So I have tried 4 different ROMs and 3 different kernels and the heat issue keeps happening. Right now I was using the latest Venum ROM and the ktoonz kernel and the phone shut off due to the heat. Stupid phone, I just got it on Sunday. Never had this issue on my epic or e4gt or gs3.

The only kernel adjustments were to the governor and scheduler (using smartass and sio, no alterations to either). I just tried using the rescan media disabler apk to see if maybe my media was causing the phone to run hot. It seemed to be the only thing going in the background.

is it heating up during usage,charging,sitting there......? have you actually physically looked at the battery to make sure its not cracked or swollen?

Usually the heat starts when I am using the phone, which is usually browsing the internet or reading up on sports news. Screen off or charging I have been OK so far. As far as the battery, it appears to be in good physical condition. I also have 2 OEM batteries by Anker that experience the same issue. So far so good, though - been using the phone moderately since the last shut down earlier today and it seems ok at this moment.

if it heats up really bad again try underclocking a step and see if that helps.....phone might be getting hot because your chip is poorly coated and the higher frequiencies are heating it up enough to shut the device down. you may have to underclock by one or 2 steps to ensure its not a consistent issue.....worth a shot anyways. unless you do high graphic gaming and multitask with 8 apps at once your really dont need the higher clock speeds anyways.

Good idea, hopefully I won't need to! Appreciate the feedback.

If you just got this phone Friday then I would return to stock, run triangle away and exchange it. What you describe isn't normal, why take a chance and get stuck with a bad phone when you are within the exchange window.

Try the stock kernel and rom and if it still get hot take it back. Try stock kernel it works man the others just cause me trouble.

Thanks all. I loaded up the latest Sac ROM and ktoonz kernwl, but disabled media scanner. No more hot issues. I guess it running like crazy in the background caused the battery to commit suicide.

Seriously guys, your S4 doesn't heat up at all???
I'm back to 100% stock everything (kernel, rom) and running this for a couple weeks. I've completed several factory resets and whatnot as well through those weeks. I know my install was clean as could be.
Now, my phone gets hot at seemingly random times. sometimes playing games, for sure while navigating with GPS and sometimes when its just sitting there. I monitor things with Better Battery Stats and keep an eye on the CPU Spy. I'm achieving deep sleep most often. Some of this is caused by the god awful Sprint service here and the constant search for signal, but I was hoping that this wouldn't get as hot as the S3.
so, should I seek a refurb from Sprint? I have the insurance. I am just afraid that a refurb would do me no better.
My biggest gripes are heating up occasionally, WiFi disconnect issues. I hope 4.3 can help some of these.

Phone died when really cold

Found an odd issue. The phone just completely died on me today twice when I walked to and from work. It was like there was no power whatsoever. Couldn't turn it on. Now this never happened before and I'm wondering if it was because it was really cold today or something. (-48C at one point) Once I got indoors and the phone warmed up for about 5 minutes it powered on no problem. Once it powered on this afternoon I found the battery had dropped about 25% from when it was on, and it just stayed at that percentage for about two hours with an hour screen time.
This is first time this happened although it's never been this cold before. The CPU wasn't registering a temperature and the battery wasn't either while I was walking.
Back when I had a Galaxy nexus this never happened. Anyone else ever come across this?

Some info about the phone would help. are you using custom kernel / custom rom or stock? Jellybean or Kitkat?

Nexus 4 obviously consisting in nexus 4 forum.
Slimkat latest build. Stock ROM kernel.

Do a lot if winter walking in Scotland and cold affected both my GPS and phone on some occasions resulting in it not operating ,as the battery temp drops it can and does struggle and the temp was no where near as low as -48 °c "that's coooold"

Happens to me all the time when I'm outside.. Battery gets destroyed by the cold.. One time I was just looking at the battery and it dropped from around 50% to around 10% in less than 30 minutes with little use.

Strange heating.

I noticed that my nexus 7 is hitting 37c really fast and around the camera front and back. Is anyone have the same problem?
And I'm doubting that it's the torrent downloader with the stupid name.

37C isn't all that hot for hardware. It's rated for twice that

37ºC is stone cold for hardware.
I wouldn't even bother unless it's going over 70ºC alot since in the long run it will diminish the hardware life.
Besides, I doubt a stock N7 will hit those temperatures even during heavy gaming unless you're living on a very hot place by default.
So, don't worry.
