My Galaxy Nexus often increases its heat to around 42 degrees Celsius (108 fahrenheit) constantly with minimal use (light 2D gaming for about 5 minutes), surfing the app store and playing around with the menus for a 10 minutes. I have installed the battery monitor widget application (free) which tells me everything and gives a timeline of different temperatures the phone reaches.
Constantly the phone is 30 degrees Celsius (86 Fahrenheit) and above, even during minimal use of apps (only running one app at a time, I selected the phone to only use 2G networks and it has no data plan).
This seems very very hot for a phone. My Galaxy S2 doesn't get past 28 degrees celsius (82 fahrenheit) under very heavy use whilst on 3G. My HTC Mozart is the same as the Galaxy, it barely gets above this temperature. Is the Nexus supposed to get this hot?
So far my battery life is set at 17 hours battery life with minimal phone/texting on 2G (literally 2 text messages and 1 phone call per day), 30 minutes of light 2D gaming and zero music or videos being played. There are no programs running in the background and the brightness is set at 40% or below.
EDIT: Even on standby without use for hours the phone has NEVER gotten below 26 degrees celsius (78 fahrenheit) .
I'm hoping someone could share info on the heat of their devices/the normal range of heat that these kinds of devices should be putting out. It sounds interesting that this much heat can actually be created, more elaboration would be better though.
bumping for answers for op.
I noticed a dramatic difference in the temperature from my evo 4g. Some potential causes:
* high stock voyages (there is a great thread in the Dev section about uv kernels)
* when running modaco's brightness patch it got worse for me.
* since it happens with the screen off, it is probably not tht...

What's your ambient temperature?
Absolute temperature doesn't tell us much, what's useful is the delta between device temp and ambient temp.

The room temperature is air conditioned around 18 to 25 degrees celsius (64F to 77F). The phone should not be hitting above this range, especially on standby. It should not reach 40 degrees Celsius whilst texting/app surfing on 2G.
Same issue here.
My Nexus One's battery is at 24C (plugged in, not charging).
And by GNex's battery is at 37C (plugged in, charging)
Okay 37 is fine but 42 is not :/
right now I have flashed a few roms and am browsing tapatalk.. at 34 Celsius. Just applied my undervolts though so we will see

Mine increase more than 42c when using too.
Just bought the phone and mine seems to overheat too much... going to buy a case....
Battery says 46 degrees cel...
also i noticed on galaxy nexus it get too hot around the camera on the back and the earpiece on the front.
noticed the problem mainly when in an area with weak reception. or while charging the phone even with good reception.
its something with the radioROM or hardware.
any suggestions??!!
normal
Its normal! 76F when not in use 90-101 in use 101-120 with charger and using . I called Samsung . My euro gs2, at&t gs2 and my skyrocket all have the same temps remember this is a very thin plastic phone with battery right there behind tiny plastic cover . Think of it like this dose ur computer get hot when u use it?? ? Have u ever even thought bout that? No cause ur not holding it in ur hand .

This is a dual core phone, it is going to run hot because it's a dual core processor with no cooling other than dissipation. It's not a problem unless your phone is actually crashing because of it. I've seen mine get up to 46C during long periods of gaming/charging.
I expect the hardware has been developed to tolerate these temperatures or we'd see a lot more "my phone overheated and now it's a brick" posts or even "my phone exploded into flames" posts. Have only seen a couple of the former and none of the latter.
Running hot after root, rom and maybe 'incorrect charger'
So like others here my GSM version Galaxy Nexus phone is quite hot at the top right corner back and front, near the camera. Only when the screen is on. Battery drops very rapidly too.. like 1% every 30-45 seconds...
This heat is brand new. I recently rooted and romed the device after the recent ICS update cause signal loss when the screen was off. I tried AOKP, various kernals and have now returned to the original backup of android 4.0.2. The heat continues with the screen being on, through all of this. Doing nothing, wifi connected... just on. Screen off no issues. No apps are installed except stock. Default Kernal again.
I also noticed i plugged the phone in with my blackberry playbook charger at the same time as all of this. The specs on that are playbook charger output is 5V @ 1.8A..
I notice a few other people posting about this so want to know if this might be rom related somehow, or if perhaps ive done something to the hardware from the charger. I've tried a spare battery that was not used with the charger at all and the heat continues.
There was no heat at all like this before this last 24 hours so its not 'normal use'. Promise Hope someone has some possible suggestions to try
Mine is at 31 right now.. listening music and xda... if play games it goes to ~35 if I plug it in it gets hotter than 40...

My GN seems to get ridiculously hot pretty often for NO reason. Up around the camera is usually where the heat is focused.
Yup around the camera is where it happens to me too. It usually only happens when I stream Google Music or Slacker
Mines gets hot there too while im just browsing

Just browsing? That can't be good. Are you rooted? If so, how high do you got your phone over clocked? Maybe you also may have too many processes opened
Most LTE devices heat up under browsing. Its not the battery that gets hot.
Also, I cannot think of a single phone I have had on Verizon that did not get warm during extended calls.
mine heats up a lot also. After talking or browsing for a while it does get warm.
What's your LTE signal strength? If you only have a bar or so, it's been my experience that the phone will heat up trying to keep the connection. At work, I've had to turn off LTE in order to keep the phone cool and save the battery.

Two reasons why that area gets hot:
1) LTE antenna
2) SoC (CPU/GPU)
Both are in the top of the phone, away from the battery. If you're taxing either the CPU or your data connection, it will heat up. As long as your battery isn't getting hot (heat increases the decay rate in lithium-based batteries) you're fine. Silicon can take a lot more heat than your hand can without sustaining damage.
I might need to get a case for my phone and screen protector

I have Battery Monitor Widget installed, and it has been enlightening. Here are my observations, using the charger that came with the phone:
The following behaviors happen on the stock ROM (using the Franco Kernel), CM9, and BlackIce:
If I am on WiFi and charging, it charges quickly, and the battery temperature reported by the app stays within the default limit (45C).
If I am on 3G, and on the charger (whether using the phone for anything or not!), the app shows the battery temp rising quickly, the charge rate drops to zero. The battery is no more than 35C based on my best guess when touching it, HOWEVER the area around the camera is very warm I (where the phone radios are). If I unplug the charger for a minute or two, the temp drops, and plugging back in will start charging again, for a short time, until it heats up again.
Underclocking seems to help this issue, as I discovered, a short while ago (playing with the BlackIce ROM, today), and I will update, once I play with it some more. This said, my suspicion is that the processor heating up is the issue, and NOT the battery, though Battery Monitor Widget claims the battery is overheating. Throttling the processor should help. Underclocking and undervolting BOTH, should help even more, I bet.
It's normal for LTE devices to warm up during extended/heavy use. It's not bad for the device unless you hear a pop or smell burning.
Heat shields FTW!

It IS, however, a problem, if your device is getting warm enough that it ceases charging itself, which has been my experience.
Imagine this scenario: Your phone is below 15% charge, and you plug it in, hoping to be able to get through the day. It charges for five or maybe ten minutes, then you see the battery level start to DROP, rather than rise. (and forget charging, in the car, while you use navigation, or play music, of both) This is what is happening with mine.
The Battery Monitor Widget says that the battery is overheating, when, in fact this seems to be processor and radio related, since it only happens on 3G (and presumably LTE, though I haven't verified it) and only when allowed to operate at a normal clock speed on the CPU--forget overclocking, that worsens the issue, too, and all of this happens, even when the device is sitting idle.
This happened to me on both the FD01 and FD02 radios (I didn't use FC12 long enough matter), so I suspect that we can rule out the radio.
Reiterating, this happens on the stock ROM (with Franco Kernel), and both CM9 and BlackIce, with their respective kernels that they are packaged with. This begs the question of whether it is a problem with the process that monitors the battery charging using up more CPU than it seems necessary for such a mundane task,
Everything else on this phone works wonderfully, so I don't believe that I have a bad device. I should not have to UNDERCLOCK such a high tech device, so that i can charge it effectively when it is sitting idle.
Any thoughts on this? Anyone else have these issues?
does anyone else is nexus get really hot when surfing the internet or doing anything else. I've only been using the phone for 15 minutes and it's already dropped 10 percent. idk its up to about 118 degrees
is this pretty common with this phone?
Clock speed
Usage
Screen brightness
Those affect how your gets.
Are u an aggressive user and clocked it up high and always have high brightness.
No only 15% brightness no over clock. New phone just got it today just seems to heat up asap...and gets over 110 degrees easily. The of course causes major battery drain. Prob normal for this phone just never experienced heat like this before
Isn't the processor on the Gnex designed to do a panic restart when it reaches 110 C's ? :/ yes its a big issue i've noticed that the phone doesn't get that hot when using stock Rom weird...
I don't get over 110 and I'm OCed to 1.3gHz, auto brightness on.

The only time mine gets abnormally hot is during a phone call. Im even underclocked and it still does.
getting hot in a smart phone this powerful is normal. I had the S3 for week, that sucker gets hot!
I agree with OP. Mine gets noticeably warm when scrolling through large non-mobile web sites. It cool when scrolling through apps like tapatalk, market, reader apps. It must be something to do with browser engine
Mine gets quite warm as well. Especially with games like gta 3 and Final Fantasy 3.

please don't forget that you're holding a device with a dual core CPU, clocked at 1200 MHz, without fan, water-cooling or anything. ever tried touching a computer-cpu?
(don't do that, lol)
Mine can easily get to 110 degrees. It definitely has a heat issue. My Razr Maxx can get warm too, but not hot like this GNex. It hurts to palm sometimes !
LTE / Camera / Data stuff . / Charging all contributes to this.
Thank god it has removable battery, since battery life will be significantly dampened by heat.
Mine gets hot since Jelly Bean... Maybe "project butter" is intended to melt our phones like butter
remember, battery temp and cpu temp are two completely different things. cpu temp will get lowered automagically in the gnex when it reaches a certain point(heat throttling is enabled in the gnex, unless you disable it), and it will shut down the cpu when you reach 110C, not 110F, that is a safety feature. 110C is 230F btw.
I've been noticing lately that when I play games for more than 30 minutes on my Gnex. The CPU gets pretty warm about 53 °c and reaches 60 if I continue.
I know this isn't that hot but the problem is when it reaches 50 ° c the pixels in my screen seem to get scrambled.
So I am wondering if this could be due to undervolting ? Maybe my CPU isnt getting enough juice.

Simple. Look at your computer. There's probably a heat sink, fan and if it's really powerful/expensive possibly even a water cooling system. CPU's get hot. That's their nature. Combine that with ever powerful phones without any real cooling solution and that's an inevitability.
The display is right "on top" of the cpu so it's only natural that the heat is affecting the display. I'm not excusing it but it seems like something with no solution.
Makes sense, to be safe should I not let it get that hot?
110°c is supposed to be the CPU kill switch. But I doubt this phone can even handle 80°c before it just plain melts.

when using wifi/4g in my house, i watched video, browsed fb and even shared internet and all. below i'll give my observations:
in wifi:
watching video, fb and browsing, whatsappin: the phone get very very slightly warm like not warm just the bit different from the phones usual temp like it hovers around 33-34.
when gaming in wifi it goes arounf 36-39 (NOVA 3) battery never crossed 31..
4g in my house, battery arounf 32-33, temperature around 37-39 for all.
but when i step out of my house, like when i'm operating my mobile in train/bus and the ambient temperature varies from say 28-32, my phone gets considerably hot and today, i was travelling in Bus and the ambient temp was around 35 and i was just browsing , watching videos and fb, my phone became hot like it even would have touched 43-46! i felt it hot to touch, is this norma(it's making me extremely paranoid)l!!??? if this is the case what happens if it's summer here, the phone would become blazingly hot, coz in summer ambient temp would be around 36-44 and all!!
Is this normala or am i unlucky for the second time ? I'm getting paranoid!
Just hit them back up

Are you serious.... When the ambient temp is 35 degree what else would you expect... Every phone on the planet will get that temperature. Can't believe you had a phone returned for this. You know the front of the device is black and absorbs light... When the sun hits your phone it's gonna heat up also. This phone is the best Android phone when it comes to thermal throttling.

With heavy multitasking, I hit 60+. Not regularly, but it has happened. The temperatures you're hitting are normal for me. I've had zero issues with the device. I have an OtterBox case, so I don't feel the heat as much. Honestly, I barely even notice heat at those temperatures. Considering the fact that the body of the device is aluminum, it's going to easily get hot to the touch.
Also, my One would almost always run between 45-70, and I've had that since launch. Used it heavily daily for years, and I still use it regularly as an app development device. No issues.
These devices have extremely powerful processors. They get hot. There's not an easy, efficient, way to cool a processor in a device like this yet, but they're designed for heavy use, so I wouldn't worry about it.

Hi first of all thanks for the reply.. I'll tell you what really made me paranoid.. Every evening I travel in bus and train and the ambient temperature would be from27-28_29.. I use 4g jio.. I just browsw/fb/insta.. In minutes my phone near the earpiece on the screen gets warmed up and it'd go around 40-41. Then I lock it it cools down fast but when I unlock it in seconds again starts warming up... My friend using same 4g in moto g4plus but his screen is cooler than mine... Please my one last doubt...
This is nothing lol. I live in Scotland so just now ambient temperature range from 5-13 °c and in my house 21-23°c and my Z3+ hits 60-70°c easily on heavy use. Benchmarked it one day and hit 90°c. The joys of the 810 chipset. Anyway away to upgrade to the OP3T so i should see and feel a massive difference.

Install a custom ROM and kernel and limit your background tasks. You may just have a bunch of things running using your CPU.
Thank you all!
Hey all thank you guys very much for replying to my thread! i'm really feeling okay instead of getting paranoid with my phone.. although i'd be very happy if you guys just clear me this last doubt!
today I was playing NOVA 3 connected to wifi in an ambient temperature of 25C, 5-10mins into gaming, CPU reaCHED A MAX OF 41c and at around 20 it maintaining at 43 but jumping sometimes 45.. this is gaming, but i get the same temperature just browsing in knda same ambient temp while I'm travelling. and also browsing in wifi/4g(fb,insta,chrome) in my house in ambient 25-27 gets the phone phone to 35-37... and the rest of the pat of the mobile is cool, even the back side is normal, only the small portion between the earpiece..
why is this happening? is this normal(it'd be great if you guys clear this)? if yup y so? and why phones like oneplus x and moto g4 etc have relatively less temp than OP3..
I know it'd be irritating to answer kinda same question again, but this would my help paranoiac freaking out for my mobile will go down..
thanks in advance for your replies

Because the Oneplus 3 is a lot faster, the Temps you are giving are n even close to hot... This has been one of the cooler phones so far.
Like others said, those temps are completely normal. Hell, I'd even expect them to be higher with your fairly high ambient temps.
About comparison with other phones - it all depends on internals and design. OP3 is made of aluminum so it'll dissipate more heat into the case - you'll feel it better. Other mentioned phones are plastic, so they'll contain more heat inside (you'll not feel so much heat, but the cpu may even run hotter).
And OP3 has cpu located just below the camera, so it's normal that it reaches top temps in that upper center part of the device.
P.S.: You talked about loads and ambient temps, but didn't mention screen brightness - that also plays a massive role in running temperatures.

Just get a case and maybe a screen protector so that you can't feel it getting hot.

hey ya !! sorry to disturb you again and again.. just a urios doubt.. what'd be the temperature of the phone or how hot can it gets, when u use 4g and fb app in ambient temperature of 29C and 33C..
mine got arounf 38-41 for the 1st cse and around 43 for the second case..
I know i'm being paranoid, ,but please, clearing tis would help stop worrying a bit
All the temps you posted are normal
About Moto g, it has much weaker SoC. A Ferrari's engine gets much more hotter than a toy car. Doesn't mean there is anything wrong with Ferrari
4G /3G active usage can get hotter than gaming. That's also normal

Nothing much to worry here. Even I use Jio all the time. My OP3 get a lot hotter than any other device I use before. Reasons I knew are these.
1. OP3 rock with a high end processor. Say SD 820. Other phones you mentioned are consisting of relatively lower end processor. So internally they might heat up more that OP3 while doing high processor intensive tasks, but the plastic casing keep the heat inside, as OP3 is made up of Aluminum that being a metal heats up so quickly and and u feel more hotter in hands than the other ones and also it cools faster.
2. AFAIK the processor is situated just below the Camera bump. Hence it heats up very quickly at that area. Irrespective of outside temperature.
3.While using 4G network it's obvious that the phonehave to communicate with the network at a very high rate than 2G or WiFi. So it's clear that it will heat up. Also using high processor intensive application like Facebook gives the processor high stress and it heats up in no time.
Remedies
1. Use a case. That somewhat helps in insulating the heat.
2.If possible use WiFi rather than 4G network. That will considerably helps your battery life.
Conclusion.
Don't worry about the warmth of the phone.Its normal. Just enjoy using the phone.
Never Settle.
Cheers.
Clearly never experienced a SD810 device. I'm sure Snapdragon took there name too seriously with that chipset. I could hit HIGH 80°c in seconds playing basic games, using the camera and under heavy usage. Had to tailer my use around my Z3+ but now I have the 3T I can do what I want and it never goes past 50°c so far.
