So I was wondering what temps you guys are seeing when your phone overheats.
My phone reboots when it hits 37 C, which seems awful low. Anyone else seeing such low reboot temps?

Mine doesn't reboot that low, the highest I have seen it go was like 43.7 or something
I've never had my phone reboot due to overheating even at 42°C. Running CM6.01

Hmm, this is getting frustrating. I've begun to reboot at around 37 C. Is there any way to change that number? Anything to reset?
Is that CPU or battery temperature? If battery then the CPU would be much hotter.

Battery... but it's weird. The battery temperature gets to 37 C, and then reboot. When I very distinctly remember it before going 45+ C without a problem.
And now I'm bootlooping. Seems to start up, and is still too hot, then reboots again. Anyone have this happen to them? Lower temp reboots?
Sounds like you may have permanently damaged your device, if your battery temp were 40+ degree celsius your CPU temp would be a sustained 15+ degrees hotter. Running your device this hot often certainly could damage it over time.

Try a standard or increasing voltage kernel if possible.

No no, my battery isn't that hot for long amounts of time, just, like when I'm surfing for a long time or something. Trying an undervolted kernel now.
Do you have a backup battery that you can try - see if you get the same results? Batteries do occassionally stop working properly.
My phone would reboot when using GPS in the car if it was on the dashboard or mounted - I checked the temperature when it booted and didn't get stuck in a boot loop and it was around 45c.....
I returned the phone to stock and brought it back to vzw, they gave me a new battery, phone still runs somewhat hot even stock.

But mine is rebooting at 37-38 C. Which is awfully low. I'm RUU'd, S-oned, and factory-resetted and STILL it happens. So it's a hardware problem.
Gonna take it into a Verizon store and demand a replacement on the spot x]
I can advisr from personal experience on your symptoms that you have one choice ... Return to verizon for a refurb. This is what happens when you have an early incredible with a faulty hardware radio. It gets to the point where it starts trying to compensate and super heats. You must return.
Every other suggestion would be a mask to an existing well known hardware problem.
I once left my phone in a black bag on a hot summer day. It went up to 50 C with no problems. It didn't reboot or anything.
I have one of the original Incredible's from launch day, it is usually around 43-45. Sometimes it gets warmer than that playing games. Never actually had any problems. The hottest it ever gets is on Z rom's. Those things have gotten it to 50 .
I'm on CM7 W/Slayher's 2.6.37 kernel, and it's at 42 just on the home screen. Mind you this is all on stock speeds. My phone doesn't like to overclock. Regardless of kernel. It can go to 1.113 sometimes, but any more = reboot.
On the HTC Incredible site, there is a FAQ which states the maximum recommended operating temp is ~60C.
I'm relatively sure there is no problem with the battery or the CPU doing up to ~90 for awhile because that's a fairly common temp for CPUs and Batteries to withstand. I'm sure that like most batteries , at >~50C it is less efficient, but I doubt the CPU is presented with any problems in that range.
Phones present a unique set of high-temp problems. Cooling sucks in those little enclosed boxes, and manufacturers definitely don't want your hand or ear burned, and are terrified of having a battery burn up in your hand or pocket, so that is probably why 60 is said to be max. I don't like picking up my phone when it's at all hot (~40C or more) but while experimenting with my own kernels and voltages and overclocking, I've had it reboot somewhere around 60C. Was it the temp, or was it overclocked too far? I have no idea, but I lowered both and stopped taking stupid chances with it.
This thing of rebooting at 37C seems nuts, inappropriate, and most likely a defective part, or one of the many services or apps that perhaps does the wrong thing (accesses verbotten memory, bad ptr, etc..)
A bad example for sure, but at work, many of our HP or Dell Racked servers (DL380's etc), are too hot to touch while running. They have enough fans to power a 747, and it just makes it pretty clear that in some cases, processors and other components can run at amazing temps.

The other day I had my phone on my car charger I picked it up and the back was very hot.The phone was only on charge for like 20 mins and it was only like 40% battery. I looked at my temperature and it said 44celsius and I then installed battery indicator to see what it is in farenheit and it said like 110. (can't remember exactly) I've never felt it get this hot before and I was wondering what temperature is to hot for the phone? Thank you for your help. Also what could cause this? A short maybe in the phone?
Were you running a cpu intensive app at that time? When I have my phone charging and I'm streaming videos in 4g, it gets pretty hot sometimes.
Personally I can handle quite a bit of hot but Mila Kalunis on Natalie Portman in Black Swan was just too hot.
Well come to think of it I ran smart bench 2010 and speed pi on it and the set it down and when I picked it back up it was very hot. I guess it's normal for running intensive CPU things. I just never felt it that hot before
Yeah it gets hot when your charging it and in a bad signal area.
If you don't want to worry about charging your phone all the time, You could buy those 2 Epic batteries off ebay, There was a huge thread in the other section. Well worth it because it comes with a additional wall charger.
These phones are pretty heat resistant. This past september just after I gotmy epic I left it charging overnight on the window sill next to my bed. I live in phoenix, when I woke up I checked my phone and immediately dropped it because the glass on the front was so hot. The setcpu widget (was on di08 overclocked to 1.2) read 168 degrees F. Phone was still 100% functional at that temp and I've never suspected that it was damaged in any way.

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

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.

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 .
+1
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?
