Ouch Ouch its burning

I was just curious to know if someone else's phone is over heating. Yesterday I was watching a boxing match on youtube with 4G on and it reached to a scary 121°. 4 hours later I was playing the nova demo with the screen at 45% brightness, played for like 20 minutes or so and it reached 112°. Just whanted to figure out if this is normal that personallyI think is not, and also if someone else it's experiencing the same issue. Thanks
Edit: Both of times I was indoorsjust in case someone is wondering.

Mine can get much hotter than that but it pretty much hovers around the 120 range when I'm browsing the web.
I also get this message when charging and watching a video. I need to exchange it. Just need to find a Best Buy store that has one in stock.

What do you use to check the temp?

mine gets real hot as well.. I think it has to do with charging while using though.

Woow thats amazing. Im guessing that those temperatures can be harmful to the phone right?
I use system info from the market to check my phone status very useful

It could be that and the stock charge pushed a lot of power in to charge quicker... But my input is that my phone hasnt even gotten very hot at all..

My phone was just laying in shotgun of my car with the car charger plugged in and the display on, then all of a sudden I picked it up and it was hella hot! 120° read SetCPU and I got shook, ripped the battery out and threw the phone in front of an AC but then I got worried that the extremities could possibly warp the board, so now Im thinking Im going to return my phone! In no way can this be good for the phone, I don't see how it can not get affect it when reaching 120, 130, 140 degrees!!! Im worried that in a week, a month, a year from now something will go terribly wrong and I really don't want to risk it, so I'm real close to returning this phone and just waiting for the Nexus!

I am amazed that a phone getting hot after heavy use is such a surprise to everyone. See any fans? see any ventilation? Here you are using a dual core 1.5 GZ processor, what were you expecting, ice water?

Ahh... Set CPU. So you can't really find the temp until you're rooted?
Hmm

Who mentioned anything about heavy usage and overclocking? CPU is 1.2Ghz stock buddy and I wasn't doing anything on my phone at the time it overheated...I have a Droid Incredible 2, and I run its CPU OC to 2.035Ghz and its never once gone over 105 degrees, so before you go getting all amazed, get your facts straight!

I have noticed this too.
With the phone simply in my pocket, my leg would feel warm. I could grab the phone and the phone would feel quite hot. Not so hot that it would burn my ear, but warm enough that it would feel like there's some kind of problem. Usually, heat = battery getting drained. When I check to see if there's anything running, there's nothing...
Right now, have been listening to Spotify for over 2 hours, and it's cold as ambient temperature. Will try installing some monitoring program and report if I notice more heat issues. I know the Evo3D used to get "burns my ear" hot when using it as GPS while connected to the car charger. My guess was that if the screen is on, and there's power going to it, it'd always get hot. Maybe it wasn't supposed to and that was just my assumption. However, same thing happens to this one; watching netflix, or playing a game, or anything demanding, and if I'm plugged, it will get really hot, really fast. If not connected, it won't get as hot, but "normally" hot nonetheless.

That you know of, did they ever fix the issue on the Evo3D?

Let me put it another way. I don't see any process or feature that will cool down the phone when in moderate to heavy use. I expect it to get hot. I have always thought, how are they going to disperse the heat?

Mine got hot on day 1 from youtube and general setup but after a full nights charge it has been great for 2 full days, no heating up or anything weird.
But man did it get hot!
Edit: I turned off gps the night this happened. I have been using my phone alot and have not experienced this again.

You need a dose of Penicillin and Cortizone. The burning sensations should clear up. In the mean time, stay away from strange phones and turn off the vibration loop - LOL
Sorry, but I've done quite a bit with my phone (videos, NetFlix, etc...) and it doesn't get warm enough to burn.

An Intel CPU (i7, for example) can run at 200 degrees Fahreneheit. In fact, the roof is about 100 degrees Celsius. To protect the CPU, there are heatsinks, fans, water cooling, etc. Video cards can also go up to 70 degrees celsius before showing artifacts; some can do much better.
We're commenting a heat that is not nearly that much for a phone. IF the SOC gets to 100 degrees celsius, that's one thing; 100 degrees fahrenheit...that is the temperature in many places around here.
These SOC don't need such fans, heatsinks, etc, because they're not supposed to reach temps of 200 degrees. They should be self contained.
On my Evo3D, which I passed on to my father, I could smell like something was burning. It wasn't, but it smelled like if it were, around the battery. Yeah, it still gets hot when in use, and specially if connected.
I believe there's also comments that on all new phones, the first few charges, while the battery adapts, the phone may be hot. Of course it had been over 2 months on my Evo3D and it still gets hot.
The E4gT is doing better today, but I haven't thrown any video/games at it yet; nor has it been in my pocket.
I'd say give it a couple days. I know I've reported my own concern, and I'll be checking it to make sure the "hotness" is within reasonable limits.

Overnight charging = phone very hot + won't wake up

Hi there! I had this problem with my Nexus twice now, that's why I'm bothering you.
Long story short - I plugged my phone to charge in the evening, woke up in the morning to find that the phone is VERY hot(area around the camera on the back) and switched off, and won't turn on. After doing a battery pull the phone switched on, the battery was full and the temperature was at 46C. It happened to me on the Monday night but I thought it is just something silly, but it happened to me today again. I was not using any hardware intensive application before I went to bed, just writing emails with my GF.
Any ideas?

ive left mine on overnight every night since saturday and its not overheating

Leave it in a chocolate tin to keep it cold, with ice below it, charge it in the morning and see if its a app
Sent from my HTC Vision using XDA App

I'd do a factory reset and see if it does the same after another night of charging with no apps on it.
If it does the same, the phones probably defective.

Have you modded the phone since you got it? Like rooting or installing any mods.
How many apps have you installed on it? Any that may keep running in the background?
If it does it again then I would advise going into Settings, Backup & Reset and restore the phone to factory settings. Then put the phone back on charge for about 8 hours and sede if the temperature goes up again. As mentioned it may just be an app thats making the phone go hot but if it goes hot after a factory reset then you will need to send it back for replacement.
Mark.

The first thing to go from heat damage is the battery. 50 degrees celcius and up is in the battery killing temperature range.
As long as it's under warranty I guess do what you want. But I'd highly recommend setting up an app like setcpu to force a lower clock speed when temp>44 celcius, just to be safe. No sense in killing a battery while trying to fix the problem.

I leave mine on charge overnight, and it doesn't do this... so I'd agree with others in that it's either a rogue app or a duff handset.

Didn't they say that one of the CyanogenMod devs was working with Samsung on the Nexus? Maybe he implemented "sleep of death" as a feature
Sent from my GT-I9000 using XDA App

The phone is not rooted, it's not running any mods. The only two applications that run constantly in the background are the DoubleTwist AirSync module and Llama profile manager(and the default weather+news widget). As both have not been tested with Android 4.0 it may be it. Is there any good app to display the current CPU usage by a process? Just like "top" in the console.

Don't know about it being hot but mine was on charge last night and died.Making me 2 hours late for work . Pulled the battery out and put back in and its fully charged ????

That's pretty much the same thing that happened to me. Except that being hot explains the issue at least partially,as the phone will switch off when overheating.

Same here, no issues with mine. Maybe do an exchange?

I'll try it for one more charge after a factory restore. If it doesn't help then I'll get it exchanged.

Mine was on charge last night and showing 28% on screen. I rebooted the phone and when it came back on, it was suddenly showing as 48%.
I think the battery reporting may be slightly borked, but this could just be down to the battery being run in. I'm just going to keep an eye on it for now.

Thank you, I have used different task managers but none of them displayed CPU usage.

I have discharged my battery pretty much completely, and now I'm charging the phone again, with my battery monitoring app running - at 50% capacity now the temperature is 42C. Can it be normal? The task manager shows that no process is using any CPU time.

That is hot but not that bad. Upper 40's celcius (47-49) is not good. And 50 is critical. Download setcpu and downclock the cpu to 500mhz while charging to help keep the temperature low in case an app spikes cpu usage that doesn't show up in task manager.
Sometimes just flipping the phone so the back is exposed is enough to cool down a phone.
Keep in mind most electronics have solder that will melt between 120 to 180 degrees celcius (248 - 356 farenheit!). While your phone should never ever get close to that, 50 degrees celcius pales in comparison. But it can kill the battery.
Seems most people who have had the problem of their phone spiking in temperature only have it happen a couple times and that's it.
I really recommend setcpu as you can have it run your phone slower when it hits a certain temperature to help keep it cool. As well as sound a notification that it has past that temperature.
It will prevent damage while you try and find out what may be causing the spike.
Though 42 degrees celcius is relatively normal for charging temperatures.
For my phone I have it set at 44 degrees celcius. I'd rather catch it before it gets even close to bad.

Thank you for your detailed explanation. Actually the temperature dropped later, averaging 35-36C between 80-100%. So the temps look good for now, but I still have no idea what caused the sleep of death issue....

Yeah,ive had this two nights in a row.i deliberately rebooted my phone and put it on charge last night to eliminate an app being the cause.
This pretty much makes the phone useless as an alarm.

[Q] One X (heating ?)

Hello,
I want to know whether it is normal, if I play a game like ShadowGun THD, after 2 minutes the phone is about 40 to 45C?
I use the Gauge Battery Widget for testing, because that shows an immediate temperature.
I also have a test.
battery recharge
Put in airplane mode.
Brightness at 100% put
Stand 10 minutes.
After 10 minutes the phone on standby, then immediately turned on the phone, the app started, and looked at how warm the phone was. And he was about 31.8C
Is this normal or not? because at play after 2 minutes the phone all at 40 to 45C.
Sincerely,
djbosanac

It is normal, but I don't consider it "OK". It is overheating badly.
The worse thing is it will also not charge when over 49... (it will discharge fast in fact)

Mine started getting that hot and caused the simcard contacts to warp. So I sent it back for a replacement. I do think the later updates cooled it down a bit but by that time the damage was done

When I was on 1.28 I had the same problem, in fact it went up to 50 degrees regularly.
After the first 1.29 update it was much much better.
Updated to 1.29.401.11 about a week ago and it seems to have gone back to how it was on 1.28!

48 is when the overheating green/red notification kicks in anything under 48 is fine.

Uhm is that automaticly, that you get a notification when the phone is overheating.
But is isent so damageable? for my phone or?
@PurpleRob how stuppid can they be, to set is as it was before the latest update? so that you have again a overheated phone ?

While on charge as soon as it hits 48c it flashes green/red, when that starts it stops charging till the temp drops below that limit.
While off charge the battery should be good up to 60 the CPU is set to shut down the phone at 99 c

Sent from my HTC One X using xda premium

I regularly see 50-55ºC even while browsing. But mine will still charge (1.29.401.11) maybe they raised the threshold? It's never shutoff on me but I've heard the upper limit for the phone was 60ºC.
I've contacted Expansys about this issue as when my phone stays above 50ºC for a while the screen yellows right above the home key. Hoping for a replacement, mainly because a case I used has already scratched the screen but it'd be nice is the yellowing and overheating was fixed.

When i check the temp_tj it says my cpu is 43,5 degrees right now, and i'm not doing anything ?
aren't some people reporting battery temp and other cpu temp ?

What software version are you running? My guess is 1.29.401.11 did something that while fixes the screen flickering, it causes the CPU to get too hot.

fellas,
the only solution currently available to reduce the heat is to use corecontrol app and change it to dual-core.
u'l notice considerable difference ofcourse without any loss in the performance..

what does it means, when you plugged in your phone to a load up again, and you get a red light? is that because the battery is full, or to heat? because when i unplug it, it is oke..

Charging
The red light when you plug it in is the phone simply telling you that it is charging, it will turn green when fully charged!

[Q] Galaxy Nexus getting way too hot

I just got out of the shower and grabbed my phone, to have it literally burn me. The hottest I've ever seen it get (while still on) was 180°F and this was way hotter, I'd guess around 250°F. Why is this? It was charging, not over clocked at the time, limited to 2 background processes, and the app "reddit is fun" was the only thing open.
Phones in the freezer at the moment, so I can only hope it and the battery didn't suffer any internal damage. Wheres the thermal cut off? (That was not disabled in Franco.kernel settings)

First you are going to need to tell us what you have modified to the phone. Also remove it from the freezer as this thermal shock can cause more damage. simply remove the battery from it. is this a stock battery? did you turn on fast charge?4was this under your pillow while it was charging? etc etc. we need more information to properly help you. and was this battery temp that you measured or cpu core temp?

Running CM10, Franco kernel. Battery is stock, no fast charge. It was slightly under the pillow (but it always is, this is the first time I had this problem since I got it in February). I didn't measure the temp (phone wouldn't even go on so I just pulled the battery before it got any hotter), its just an estimate because I know it was above 180°F.

Cells are storage tested at 65C and charge temps can reach higher than that. I wouldnt have a panic attack over this instance but the next time you charge it, monitor it with a battery app that displays battery temperature. Your battery could be going bad.

Download System Panel from the Play Store and monitor your CPU activity and active apps. I've had rouge apps churn my processors @100% before. It's a sure fire way to generate heat!

What temperature is your Pixel XL operating at?

I started another thread that has yielded zero useful information so I thought I would be very explicit this time about what I am looking for. I'm trying to figure out if I should RMA my device or not. My device is currently 98F in a 70F room and I'm doing nothing but typing this message. This seems like a high temperature to me but for all I know it's normal for this device. If other people who use battery monitor apps that include device temperature readings could let me know what temp their Pixel XL is operating at I would appreciate it and it will help me decide whether I should RMA this device or not. Thanks in advance if anyone actually responds with useful information.

That's the same temp as mine after conversion. Maybe that's a normal temp for this phone. Thanks for the response!

The Pixel is designed really differently than my previous phones so I'm having trouble figuring out what is normal on a Pixel. The CPU frequencies that this phone operates at would result in a significant performance lag on my previous phone, for example, but with the Pixel they result in the phone running very smooth and fast.

I have not messed with my frequencies, I'm running OctOS with the Elemental kernel at whatever it ships at.
so I went ahead and let my phone sit in my center console on my way home. for some reason the sun cooks this area of my truck and it's hot to touch even with the AC. After my trip home in 103F weather it was at 42C and did not shut down (I was streaming music over bluetooth from amazon music)

Idle : 30 - 35 C (phone goes below 30 C only when not used for more than 15-20 mins in a very cool room).
Medium Load: 35-40 C
Charging in the car, Charging while using Chrome etc: 40-44 C
Heavy Load: 42-48 C
I have owned Nexus 5, Nexus 6 and Nexus 6p previously. This phone definitely runs hotter than all of them.
I got a replacement from Google, but it is the same problem.

I don't have air conditioning in my car, it was very hot outside, the phone was sitting in a cradle in direct sunlight and I was using the car charger, GPS and Spotify all at the same time--so it's possible my phone got much hotter than 42C when it did shut down. But I used my Nexus 6P and Samsung Galaxy S3 and S6 under identical circumstances and none of them ever overheated and shut down. They also didn't run anywhere near as hot as the Pixel XL when idle. My phone is generally 90-100F in an air conditioned apartment when I'm doing absolutely nothing with it--and multiple people have responded with similar temps for their own phones. If the idle temp for the phone is that high it's going to get super hot when using it under more demanding circumstances.

No problem. Have you observed higher battery drain when the CPU heats up? I'm not sure phones are meant to be that hot. I haven't seen any other flagship heating up so much.

I've never heard of another flagship phone that operates so hot. Battery does definitely drain faster the hotter the phone gets. But mine gets to 100F doing almost nothing.

Yes, mine get to 100-105 F range quickly on battery temperature.
Yesterday I had the following youtube, whatsapp, Browser and Gmail - I was switching back and forth and the phone was on 43 C (110 F), (granted I had 1080p video on and was chatting to a friend as well and responding to emails).. I had to then clear all apps and stop using the phone to allow it to cool down. The CPU temperature was over 58 C (measured using elemental X kernal with root access).
Something is wrong with either the 2 NEW Pixel XL phones that Google has provided me OR with the Pixel XL phone in general. There has to be a hardware problem. Maybe some phones are worse than others? Maybe it is a quality control issue?

jesus 58?! mine only got to 45C and that's letting it sit in my center console while streaming youtube with the screen on

Well, that was CPU temperature. The battery temperature was 43-44 C. I had to use a custom Kernel with Root to measure CPU temp, as most apps only give battery temp.

haha oops, I had no idea EXKM did that, just enabled it to see how my cpu fares

Thank you. EXKM will put a persistent notification.
I would be very interested to know what your temperatures are under mid-heavy load : both the battery temp and CPU temp.
It's basic knowledge that heat destroys processors and other circuits. I have to use coolers and thermal paste etc in my home computer when it gets too hot. I can't see why it would be different for a phone.

yeah that's why I was so shocked at the temp, get the inside hot enough and any soldered components will begin to loosen. well lets see how it does

Google tells me it's 34° and the battery is at 42.2°
I'd love to check with Daydream!

The phone is known to get very hot with Daydream. I'm more concerned with how hot the phone gets under normal operating conditions. My battery goes from 80F to 100F in seconds if I do anything as light as surfing the Internet, reading my email, browsing the XDA app or using the EBay app. 100F seems to be the base temperature of my battery if I am using the phone for anything. I suspect that Google knows these phones won't last more than a couple years. I'm not sure if I should wait to find out or just get rid of this thing while it still works. At least in the Nexus phones you had the option of flashing a custom kernel and changing the governor so the phone would run cooler. You can't do that with the Pixel--the phone runs at the same temps or even worse on a custom kernel. I already tried. I've never owned one but I'm curious if the Pixel XL runs significantly warmer than an iPhone. Or for that matter a flagship Samsung phone--other than the one that blew up, obviously.

So XDA went ahead and showed what the surface temp of their pixel is under their tests
http://www.buildcomputers.net/cpu-temperature.html
I thought the temp of the cpu temp was high, but compared to other processors this is pretty average/on the low side

Turns out that's no where near as hot as it would need to be to be a safety issue for any of us.

if you're concerned why samsung exploded while ours hasn't, they have a good explanation about the construction of those batteries being flawed.

I'm not concerned with safety. I'm sure the Pixel is perfectly safe. I'm concerned this phone is going to eventually bootloop like the Nexus 6P, the Nexus 5X and multiple LG phones. I'm not one of those people who wants to have the latest of everything and if I spend a small fortune on something I actually want it to last for a long time. I do appreciate the links you provided and will look at the info later. Thanks.
