Sprint nexus gets hot... Kernel?

If I use it more than 10 min it starts warming up.. 15-20 min and it almost burns to the touch. Is this a kernel issue? I do have a custom kernel running.. Could anyone recommend a kernel? I am currently running teerom

Mine does the exact same thing all the time. I'm not rooted nor do I have any custom roms. I'm 100% stock.

"hot" is relative desriptor, its not a temperature but how something feels as compared to something else. can you give us a tempurature? was it plugged in?

yea, that would help with setcpu. search battery temperature in the market, theres a bunch of free battery apps that give the temperature reading.

yup, thats hot!
what are you using when it gets so hot? watching a movie in flash will do it, gaming will do it when plugged in(but youre not plugged in). my guess is that the lte 4g radio could do it also, especially if its trying to connect but cant. ive heard of verizons galaxy nexus getting very hot with the lte radio on. my gsm gn only gets that hot when its overclocked highly and im putting it through a tough benchmark regiment(when trying to get it that hot). it could also be a defective battery.

I've had many sprint phones get hot while downloading lots of data over 3G. It particularly happens when I do "update all" in the android market while on 3G. Burns through battery power real quick.
This is mainly due to sprint's crappy/obsolete 3G implementation trying to keep up with modern data demands.

I'm having the same issues. I might just sell the phone for now while I can for around 400$ then re-buy it once it hits a lower price

deleted post.
move along, nothing to see here..

Just an FYI, that screenshot is a picture of the battery temperature. Not the CPU temp. I believe that the maximum temperature the Galaxy Nexus' processor can withstand is 100 degrees CELSIUS, not Fahrenheit.
At deep sleep the lowest my CPU reaches is 80 degrees F and my CPU is ALWAYS around 95 degrees F when in light use and rises to about 145 degrees F when browsing or using an app.
And I believe you must be rooted to check CPU temperatures anyway. Franco's app shows the MPU temperature and you must be rooted to check it.

179° temp this morning when I woke up...

So last night. Just like everynight I plugged in my phone. Left it on my bed. And woke up this morning. The phone was off and it was so hot to the touch I could barley hold it. No exaggeration. I actually have a screen shot of the temp when it first booted up. Its was 179° .. I don't know what caused this.. but I hope my device wasnt damaged at all last night. And I do not know the culprit. It was just random.
Here is a screenshot of the temp through francos app. Oh and by the time the phone booted it actually cooled down a little bit so I'm betting the phone hit 110°c last night and shut its self off. The weird thing is it was still hot while it was off just charging...

You should attempt to replicate it for the purpose of identifying the cause. It's likely the charger, the first place I'd start. Have you rooted? Are you OC'd? Have you recently installed a new ROM or changed anything?

I am rooted. I was over clocked to 1.5 GHz. And I actually just installed nightly #221 but I'm trying to figure out why it was still hot after it was off..

My guess is that the charger is giving it too much juice, at least when the phone is shut off and the battery full. Is it the stock charger? Also, it could be possible that the software that regulates the charge isn't functioning properly and you woke up shortly after it had shut off.

I am using the stock charger.

Would have been quite the wake up call.

I can bet you have disabled thermal throttling? If so, then: 1.5GHz+charging+some app using 100% of CPU resources = +110C is very likely.

Even at 1.5, I still don't see what his phone could have been doing to get that hot.

The only time my phone gets over 110 F is with my otter box on in the sun

Charging always locks the phone at 350mhz (keeps out of deep sleep) if it is on.
Sent from my Galaxy Nexus using Tapatalk 2

My opinion is that it is probably your charger giving the phone too much juice... HOWEVER, why is your charger giving the battery too much juice? you should check the fuses in the house. if you have the charger plugged into one of those multiple outlet bars, those tend to overheat electrical appliances. plugged something else into that same receptacle and see if it gets got over time

The first thing I checked was thermal throttle. I'm not using a power bar. Uhm. Yeah I'm not exactly sure what was up with it. The only thing I could think of was it was slightly under a pillow. But still.. I don't see it getting so hot while being under a pillow with no pressure being applied to it. Tonight I'm going to try and replicate what I did last night but with CPU spy on. Maybe there is a rogue app cause problems. Who knows. Oh and recently my phone has told me twice in the past few days that the Sim card was removed. And when I touched the metal over the Sim card it was hot as hell. I think I might have a defective phone at this point... I've never really pushed this phone. But it runs hot sometimes. Very easily. And what scares me is since I had to get a refurb.. damn insurance.. it was unlocked when I got it...

Just normally charging and light browsing right now and I'm at about 156° I'm not sure what to think of that number

Yes, I've experienced it with custom kernel (e.g. franco) but with stock kernel phone sleeps well deep during charging. (For sure I've tested it now, so this is 100%.)

120°F / 51° C seems very hot to me. My Gnex is on 84°F / 29°C. Even after playing high performance games it doesn´t heat up more than to 111°F / 44°C
What Rom / Kernel / Build are you running?

I'm running the latest Vicious/CM10 w/latest Franco but I've tried several other ROMs...none of my other gnex's ran this hot...it will go up to 160 with the slightest task to the point where it is uncomfortable to touch on the upper part of the screen.

maybe try the paranaoid android rom http://forum.xda-developers.com/showthread.php?t=1619582. there are a few reports about overheating with the stock CM10 kernel, but works perfectly for me. solutions there are switching to trinity kernel or franco as well. but mainly the overheating shoult result from a bad kernel.
If you don´t want to put on another rom, maybe switch back to an older / stable version of francos.

I don't think it is a kernel issue because I just got this replacement...(have had 6 gnex's...long story) was running the exact setup...never had any heat issues until this one. Even when it was bone stock I noticed the upper part of the screen was hot to the touch.

then give back to your reseller. sounds like a factory problem then. phone shouldn´t heat up this much. not even it´s uncortable it may crash your phone (or parts of it) in the long run.

That's what I was thinking unfortunately...on to gnex number 7 I guess
Sent from my Galaxy Nexus using xda app-developers app

yeah unfortunately maufacturing standarts for the GNex are way below than these for samsungs own devices. but better exchange it now then beeing said it´s your fold if the cpu melts or something

Ya that's too bad...calling Verizon first thing in the morning thanks.
Sent from my Galaxy Nexus using xda app-developers app

i feel like you two don't know what you are talking about and idk wtf you are doing to your phone that you've had to return 6 of them? derp but, that's besides the point
now the issue at hand, i've had over heating since jelly bean on custom roms which has shut my phone down ... it seems to be a kernel issue as far as i can tell ... i'd recommend trinity's TNP1344-307-JB-STABLE35 http://goo.gl/jry8c
if the problem persists go back to stock ... and quit sending your phones back you are the reason why carriers don't want people to unlock their bootloaders

50°c is normal operating temp, the gnex has a thermal throttle that kicks in at around 75°c, then it scales down the cpu. You also have to consider the ambient temperature outside. Its 95°- 100°f here during the day, of course your phone will run a little hotter when its hot outside. Just use your phone
Sent from my Galaxy Nexus using xda app-developers app

Just dip ya phone in water, that should stop it getting to hot :cyclops:

Most of the phones I sent back I did not modify at all...asurion sent me 5 defective devices that all had hardware issues...(faulty screen, broken buttons, no radio, DOA, etc...probably refurbs), they then reimbursed me for buying a new phone through Verizon and it does not have any of those issues. I tried Trinity and it is running slightly cooler now. As for me not knowing what I'm talking about, that is why I asked in the first place. I didn't know what the average running temp. is.
Sent from my Galaxy Nexus using xda app-developers app

Just flash back to stock and see if you still have the overheating. If nothing changes you have a defective phone. I don't think my gnex has ever reached 120° F even with some mild overclocking and heavy use.

Are you guys all running stock kernel and ROM or custom? I'm on stock.

Ha! Try hours with GPS, Bluetooth music and Tethering on... the heat seems to really hit while I'm charging and doing all that. Fact! I can't touch the ass end of the phone. It probably gets about 8 hours a week like that. Still working perfectly. Samsung tells me it's normal. It also has a lot of factors for me too. I use a 1 amp charger. After 96% it's not so bad. At night when brightness is down. Not as hot. I tried to get it to mess up but couldn't. GPS, Bluetooth, tethering, charging from 30% and 100% display, and I pushed out to a low coverage area. Didn't miss a beat or melt. Lol.

Navigation makes phones really hot, but with normal usage it should stay within 30-36°C.
I like this phone's heat management more than my old phone. My Evo 3d would get hot from 10 min usage.
On this, my screen has been on for 2 hours straight and I'm running at a cool 35.1 °C.

When I was running CM10 for a day or two I thought my phone would melt but it was also 90+ degrees outside so it was hard to tell. My phone gets a little warm, but nothing too worrying.

It actually shouldn't be expected. The Snapdragon S3's also ran at 1.5ghz and was pleasantly cool and the Exynos on the Galaxy Note was at 1.4ghz. Both are less power efficient and should run hotter than the S4. I've used the Evo LTE for a while with the same S4 and it barely got warm on a hot day. The issue is with the second core being weird. For those that hasn't already, make sure you flash Freeza's fix, http://forum.xda-developers.com/showthread.php?t=1790061 . This fix made my phone cool and got rid of my quickly draining battery life.

Most of the time my phone will stay within "normal" (to me) range, but when I game heavily... it turns into an oven range! I've gotten so paranoid a few times, I took the battery out and let it cooled for 5-10min

Im having the same problem....it isnt the software thats causing this its the hardware
Sent from my SPH-L710 using xda premium

I hope you guys will repsond to this... What do you consider to be "normal" temperature for your phone to reach? Is 35 degrees realy normal? Ive heard people with s3 talk of theirs only reaching temperatures of 29 degrees max.
Thanks.

[Q] my nexus heats up

Hello
My nexus heats up while charging or playing games or doing heavy tasks, the heat builds up around the camera. Am I the only one having this "thing" ?

Nope. This is common with this phone. It may be a rom/ kernel issue. Unless your running stock, then I don't know. I have it too and if my phone gets too hot it doesn't charge until it cools down.
