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

"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.

How hot does your S3 get?

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.

Sent from my SGH-T999 using xda premium

I read somewhere that one or both of the cores aren't managed efficiently and switch govenors from ondemand to performance which the phone isn't optimized for causing the heat issue. I actually put my phone on performance and it did get hot so I think this may be true, I heard that there was a script or something that fixes it called restore dual core or something like that but I think it was for the international S3 so I don't know if it will work with our devices.

My stock rom also used to make the phone heat up but it's always at the very bottom. Anyone know why that it?

Sent from my SGH-T999 using xda premium

I figured that the phone heats up due to processor usage.
My guess would be that the processor is located behind the home button, therefore when you're running an intensive task (or doing somethings in general) the processor has to increase the clock speed thus heating the device.
It's really annoying actually, makes my hands sweaty sometimes when holding the phone.

I had this phone heating up on me while I was on stock too, but ever since I switched to AOKP with Lean Kernel the heating has been dramatically reduced for me. And by dramatically reduced I mean it rarely heats up unless I'm doing something up that takes a lot of processing power like a 3D game.

Average battery temperature

OK so I know pie devices get relatively hot, but when just having my screen on and typing on here or using root explorer it goes up to some 90 degrees. And it just concerns me because my galaxy s2 hardly guys 90 even while playing intensive games.
I'm just curious if 90 is normal or if I should get a new device through warranty.
Thanks everyone.

When I was using SetCPU, I saw mine hovered between 80-90 most of the time. If it is bothering your hand, put a case on it. I use an Otterbox Defender and I can feel the heat through the case sometimes.

In my experience this generally hapoens either after a new rom flash or just at random (seemingly). But it has always eventually calmed down and stays cool after that.
I suspect it is searching for mor something....like updating libraries of songs and whatnot. Seems like it occasionally gets stuck and when you add additional load it easilyy heats up. Try using Show CPU Use in dev options and keep an eye on the top few processes while it heats up. May give you an idea as to the real cause.

Phone Over Heating Issues

I have an issue with my phone overheating. Meaning my battery gets ridiculously hot. Its hot the the touch especially during use of my data or heavy use in general. I know it's not a ROM issue nor is it a kernel issue. Why? Because I have gone back to stock and it actually gets hotter.
Would simply replacing the battery with another OEM battery fix this issue? Or can it simply be the hardware? Or could it both? Would it be worth a shot to replace just the battery? I wish I took the time to take it into T-Mobile when I first bought the phone, but I assumed it was because it was stock. (Dumb decision, I know). Any insight would be appreciated.

get a battery and phone temp app and report how hot it actually gets. Maybe get a case if its not abnormal type of hot. I live in Phoenix AZ and it gets up to 118° here and I'm outside using my phone mostly if in shade and I've seen my phone get to 124° granted it wasn't good and I wish that didn't happen, no harm was done.

Judging from past experience, are you shore it is the battery? It is actually extremely common for the phones proccessor to react differently to different roms and heap up which will cause the entire back of your phone to be hot to the touch. The proccessor is located right below the battery compartment. If this is the case I would first try flashing a different kernal and also check to see if your proccessor is overclocked and perhaps lowering the maximum mhz. Usually around 1096 is a pretty good low speed that will still keep your phone fast in my oppinion. See if that helps you. If it is the battery, the only real cause might be a defective battery in which I would stop using immediately since it may cause damage to your phone.

I've tried different kernels and the best kernel that works for me is Ktoonez. I actually have it under 1.5ghz. Like I said, even being stock the battery seems to get really hot. I'm going to purchase a battery and see if that changes anything.
But since I did change my modem as well it seems to keep the phone a little more cool. Just using the phone can get really hot to the touch even with my otter box on it.

Personallyc I think cases only increase the temp, not decrease. Only if it were aluminum or made of some other heat sink type metal will it actually help with dissipating heat.
If the modem helped a little, try flashing the LJC firmware from the dev section. There is a thread there with this firmware in recovery flashable form. Wont affect your current rom or setup.
It could be your battery, but I'm just not so sure it really is. These phones can get hot, that's pretty normal.
Also check in settings on what uses the battery the most. Perhaps a service is getting hung and sticking at full throttle!
