Processor gets hot

I'm concerned that the phone gets too hot when playing games.
Sometimes just browsing the internet causes a warm spot.
The hot spot occurs on the top corner on the left side.
I'm wondering if the phone is going to last 18 months if it goes through this cycle on a weekly basis.
What do you think?

the problem is that some of these games can be a bit demanding and considering this GN uses a Omap 4460 CPU it's no wonder that it's struggling.
it's a shame this phone didn't get one of the newer Omap 5 series.

Not so hot mate... you havent owned a GS2 to witness the real hotness

Welcome to Smartphones, all of them get warm or hot when playing games on them. If you tax the phone really hard it will get warm/hot as well. Regardless of what CPU they have.
It will last perfectly fine, dont worry about it. Think of it as a added bonus, a hand warmer.

or if you're female and it's that time of the month(cramps), it doubles as a heating pad for that area.

Getting hot

Anyone else's getting very hot. I already returned two rezounds for getting up to 150now my nex is up to 111 right now and all I was doing was playing around on Facebook. Most of the heat feels like it is on the top half of the phone and the screen gets extremely hot

Is your brightness up high? And also are you charging it while playing on it
Sent from my Galaxy Nexus using XDA App

Charging now wasn't then and yeah I keep brightness up otherwise the screen is way too grainy. You should be able to use your screens top levels without scolding your fingers lol just curious if this is a common thing or If I have to yet again get another phone
Rolled out from my Gnex Prime

My phone heats up on the top part like yours but mainly when I use it while it charges or if I keep the screen awake for about 20-30+ min straight.
Edit: just like your laptop or TV or psp or any other electronic device lol

Not seen any issues on mine so far and it doesn't get as hot as my iPhone 4S when that is charging and/or using bluetooth for making calls.

yeh my phone gets quite warm also , crazy thing is when it gets warm im sure it affects the colour temp of the screen.

Mine gets hots quickly when I play Riptide a lot.

I noticed this too, but. I don't feel it since its just the top half and my hands are gripping the bottom half. I do feel it when I stick it in my pocket and my thigh gets really warm.

Mine heats up at the top back only when I'm using mobile data to do stuff. But I can use wifi all day with top brightness with no overheat. Stupid.

like right now. I literally just turned my phone on 5 minutes ago and am on wifi and I can feel the top getting hot
Rolled out from my Gnex Prime

when I got my phone a few weeks ago (GSM 4.0.1) my phone easily warms up especially at the back near the camera area. After manually updating to 4.0.2, I really noticed it was gone. Now even I am watching youtube videos for more than 20-30mins my phone doesn't warm up even a bit unlike before i got it on stock 4.0.1 in which just turning on a wifi connection and gps warms the back of my nexus without running an app.

Define overheating. Because i think the phone does quite well for how much horsepower is under the hood. Mine gets warm doing this, that and the other. The only time i was seriously concerned was watching a netflix movie over mhl and really i was really only concerned about the battery temp than the phone. The phone and its components are a big step up from phones 3 years ago. People used to whine about phones getting warm when 3g heated them up and 3g was becoming the norm. Fast forward to today and there are more powerful components packed into less space, and less ventilated at that. If you dont like your phone warming up get a dumbphone and be done with it. I think the nexus and most other smartphones do quite well. And this was before i undervolted it. I can only imagine how many useless threads will pop up about heat when quad cores come out. Personally when i upgrade next, hopefully two years from now and not the annual phone i am accustomed to, i hope a dual core cpu and gpu at 28nm or less will be sufficient and be well within the thermal windows and limits for how powerful these pocket size devices have become and dramatically changed our social lives.
Crazy world, ay?

mine gets hot up top on my ear when I'm on a call. I found at least by switching to the new 4.0.3 radio and doing a combination of over clocking + under volting it doesn't get nearly as hot anymore.

I'm talking when my battery temp is 111° and the top of it feels much much hotter than that. I'm on 4.0.2 I understand the phones will get warm but they shouldn't from ten minutes of Facebook. If I was watching Netflix using my GPS and doing so over 4G then yeah scold my hand I get that but not frickin Facebook or internet browsing or anything like that. I really like the phone and ill be keeping it but apparently won't be playing many games lol

I use a SetCPU profile to peg back the processor to ~700mhz when the temp gets over 40c

Whoa, it's overheating? You might have a defective phone. Mine gets pretty hot but the heat hasn't led to any stability issues or damage like yours. (Note: It's not overheating if there's no damage, so I'm assuming by your text that your phone got damaged)

Mine gets pretty hot but the operation of the phone has been fine. It sounds like all of the phones operate basically identical to this.

No not damaged. I leave it alone once it gets real hot. I've turn down my brightness to help prevent it a little. Def doesn't look as good lol

Galaxy Nexus Overheating

So I just got the Galaxy Nexus (upgraded from the Nexus S) and just after the first day of use (no heavy workload, wifi or GPS) this thing became painfully hot. We're talking touch it to your skin and *ouch* hot. Strangely the massive heat output seems to be limited to just the top quarter of the device. Also note that it takes only about 10min until it reaches 'unusable' status.
Does anyone else have experience with this problem? Admittedly I was warned by the provider I got it from that they had had feedback from customers about it's excessive heat output and other people I know have also commented to the same affect. But I never thought it would be quite this bad. I could fry an egg on this thing. Considering my Nexus S never had this issue - this is disappointing. Are we talking hardware design fail? Or perhaps a bad batch in my country?
If this was an iPhone they'd be headlines going on about 'heat-gate' and Larry Page coming out saying that we're 'cooling it wrong' lol

the nexus does get abit hot around the camera area, but it shouldnt be THAT hot lol.. what are the ambient tempreatures around where you're using the phone?

Not that hot - maybe 20-25c

Perhaps monitor battery temp with an app, it won't give you a precise indication of your processor temp, but there should be a correlation. The phone does get warm around the camera area, but never painfully so (for me). Was your AOS usage abnormally high?

I think the OP is overreacting just a little, if it burned you then the phone would have melted
Anyways, its perfectly normal. the OMAP4 chipset runs really hot, I read somewhere that it operates normally between 85-105 degrees Fahrenheit.
Here it says that the OMAP4 platform has a temperature range of -40° to 85°C. I think thats overstating it, but its all there

Well let me put it this way. It's hot enough for me to consider claiming on warranty. No phone should generate that much heat right next to your head/ear. That's unusable in real terms (at least with this particular one). And i've had my fair share of android phones in the past to compare...

The Tegra2 chipset runs VERY hot when overclocked as well, I've had hot experiences on both my Galaxy Tab 10.1 and my G2x, and I can also say that the OMAP4 runs hotter than that! Just offering opinion is all, it's perfectly normal for it to be running extra hot, and it happens fairly quickly.
I completely agree with you that the phone does get abnormally hot, but then again, from my experience, so does the RAZR with a sister chip in it.

Android 4.0.1, stock Nexus Galaxy, going on 2 weeks. It's in an otterbox defender case, after 1.5 hours of running video it's warm in my hands, but that's under constant workload that nearly drained the whole battery. In other words during normal operation I am not finding the serious problem you are describing. Empathy out to you.

What temps we're talking about? Mine stays at +36C +38C while browsing web/watching youtube and gets a bit (around +41C) hotter when playing games. And these temps are far from hot-to-touch.

Sometimes my GN becomes really hot too. It also happens when i'm watching hd video for a half an hour or more. Then it turns terribly hot.

mine goes to 48C and then it starts lagging like hell

Mine gets warm around the camera and earpiece. It's pretty normal, I'd say.

There are multiple threads on this, but I'll say what I've said before: it's a dual core device, it runs hot, it's not "overheating" unless your phone is crashing, shutting down, or otherwise obviously malfunctioning in some way other than getting hot.
What do you mean by "it reaches 'unusable' status" though? Are you just afraid of using it because it seems hot? Mine gets quite hot when I use it heavily...have kept it going for several hours in this state (while plugged in) with no other issues.

Mine gets hot in the same area, but it has never been that hot, just warm. My OG Droid was OCd to 1.3ghz and that literally reached 150+ degrees F quite a few times and is still fine to this day. The OMAP SoCs seem to run a bit hotter than others, but they can definitely handle the heat.

Basically out of the many smart phones i've had in the past. This is the first that I would say I would refuse to hold it up next to my ear due to the excessive heat. It's bad enough just holding it landscape to type on let alone sticking next to my head. It's really annoying considering how otherwise the interface and physical design of the device is better then anything else i've seen on the market.
I think i'm going to get one of those laser thermometers to find just what the temp on the surface of this thing actually is.

It's hot on the back of the phone like other uses have said, not the front where your ear would be (unless it is which is an entirely different problem). Plus, when your phone reaches those temps through extraneous use (videos, games), you normally wouldn't be putting it near your ear anyways. I don't see this as a huge issue. If you do something taxing, much like a computer, expect the phone to work a little bit harder and hotter.
Oh and I doubt it's hot enough to fry an egg. You would smell the plastic melt first.

I've had once when my GNex was really hot. It was when I try factory reset many times since there was a bug that factory reset does nothing in a custom rom. But I didn't know at that time. I tried reset, flash rom, reset, etc. My GNes ended up really hot.

The only time my galaxy nexus got really hot was when I was switching kernels every 2-3 days, and one kernel (I think it was one of Franco's earlier builds) made it run hot even when I wasn't using the phone that intensely. Changed the kernel, and it's never been hot since (I play games, listen to music, browse web, push notifications, etc.) I don't do much video/HD streaming though...

I have been getting that too. Around the earpiece gets warm when only slightly used. Also, I can hear a faint buzzing humming sound from there. Open the back cover..can hear it from the camera too. Is something wrong with my phone

Q[How hot does your phone get]

My first Galaxy S3 went back due to excessive ink markings on the screen and since getting my replacement I have noticed it running hotter than I remember the first one being. The heat feels to be coming from the lower half of the screen / back of the phone.
I compared it to my friends phone and his gets just as hot. I am running FreeGS3 v0.1.0 and my friends was running stock - non rooted.
I ended up going to Sprint and the tech at the store replaced my phone with a new one out of the box and it is displaying the same behavior with temp.
I see no ill effects from this and am getting pretty good battery life for my usage, it is more of an annoyance for my phone to get so hot though. It seems a little warm for just browsing the web or FB on Wi-Fi so who knows.
It never seems to be the battery temp, but the CPU temp that climbs and is responsible for the heat.
I should point out that I had a Speck Candy Shell Case on the first phone, but that case has since been broke and returned. It is possible that my first phone got just as hot but somehow the dual layer design of the case disappated some of the heat, but I still feel it on the bottom half of the screen. My EVO LTE didn't get this hot in the few weeks I have it, and I have an Airave at home where it still heats up so I think we can rule out signal strength as a cause.
Anyone want to chime in with thoughts or suggestions?

Mine does that too, thought I was the only one.

Network related I think. Not necessarily signal strength but a poor data connection.mine gets hot as hell at the Bottem where the antenna is when my data is horrid.my roommates s2/e4gt Does the Same thing except at the top of the phone where the antenna is on that phone. Which would explain the battery life not being affected. The poorer the network performance the hotter it is. Sound familiar to anyone? Put the phone in airplane mode.and stress it in any way possible.overclock and run a benchmark while trying to play a game.what ever comes to mind.just leave in airplane mode and I bet it doesn't get nearly as hot as what your describing. I had a galaxy nexus on Verizon that rarely got hot. Where as my mother just got a sprint galaxy nexus which gets hotter than any phone I've ever felt but only with poor data speed as well. I've hit 120·F on my s3. I've seen her gnex hit around 140·F. So I'm blaming the network

Idk if there's a bug, but check with betterbatterystats and see if gsiff_daemon is running at the top of the list... if it is, it's probably causing the battery to get hot, along with draining battery. You can fix it by using Root Explorer and renaming that file to gsiff_daemon.bak , it's in system/bin

Sure - any huge data usage, (especially with 3g/4g/lte) will cause the phone to heat up in the cpu area - this can be coupled with high graphics usage, and/or high ram usage -
electricity generates heat as a waste product - it wont get too hot, but it will heat up.
My gs2 would occasionally get so hot i didn't want to hold it or let it sit in my pocket
My new gs4 got plenty warm when redownloading my podcasts, and durring the first google device restore.

For me so far, the only time it is noticeably warm is when I use the camera for an extended period of time. Haven't played any intense games on there though like NFS.

I find that my microsd card get hot when accessed a lot, but that's not new, same as in my S3.

Mine is hot too. I haven't done anything though.

I believe there is firmware update that is compatible with the I9505 Tmo variant. You may want to do some searching and check it out.
The main S4 forum is a good place to start.

Heat is not the same thing as over-heating. These chips have a maximum operating temperature rating of upwards of 70c. There are a myriad of reasons why any two devices would operate at higher or lower temperatures including ambient temperature, radio actions (high-throughput or low signal recovery), and of course running processes. There will always be people who think their phone is "too hot" since it is a purely subjective claim.

yeah honestly is at 40c and thats beyond hot!!

Yep, mine heats up on the top back of the phone. But it doesn't overheat when I'm on the phone though. I talked for over two hours and the phone stayed cold. But if I play around with menu and installing apps, it gets noticeably warm. I used S2 for two years and didn't remember it getting this warm.

but it heats up top Samsung name area like u can feel it in like 10m lol

Like others mine heats up at the top back at times but never to a serious, uncomfortable degree. Pretty sure my Blaze would get hotter at times from less taxing usage.

So hopefully this is just software related issues and not hardware.....

Try turning down the brightness of the screen, I saw some reviews say the density of the screen adds majorly to the heat.

I have to wait 20 days to exchange it. I could return it but my micro SIM card doesn't work on the S2.
Anyway, I just received an OTA update.....

I've used my micro sim in a GS2, a MyTouch slide and a G1. It will fit, just line up the 3 pins to the 3 plates on the sim and it will work
