Overheating

The TP has a problem overheating, did they manage to fix that with the TP2? When I use my phone I typically have several things going at once and the TP just overheats, won't charge, and drains the battery.
So the question is can the TP2 handle multi-tasking? (using the GPS, listening to a radio station that is streaming over 3g, and playing that radio station to my car stereo via bluetooth)

I have been abusing my TP2 daily with Wi-Fi and 3G (push emails) and no overheating whatso ever...

My TP had that problem. Specially using TomTom/IGO on sunny days. No problems with TP2 (Spain, August, 40ºC)

don't tell me these things overheat easily. that won't bode will with the 50C+ temps we get here.

thanks for the info everyone

My TP also would get hella hot when using tomtom but never overheated. Never crapped out due to too much heat. I have abused the thing besides that and have not had any problems. Same should go for the tp2 since it remains with the same guts.

Well I got mine and it overheats when I try and use it and charge it at the same time. Especially using the GPS and charging.

Are you using the OEM charger...i know the Non-OEM ones suck and make your battery hot anyways.

Yes, that's really the only time the Rhodiums seem to get warm is when they're charging and multitasking and/or using any one or more of the radios at the same time. Mine doesn't get warm on the wall charger...until I start doing anything more than light texting maybe.
Be careful about doing that though, even if you don't see an immediate performance hit. It can affect the lifespan of your battery, and is also one of the suspected causes of the dreaded (and increasingly common) Newton Ring

[Q] Battery overheating

Hi there,
I've been using DHD for more than 2 months, and I have problem (or feature, depends what month it is
Where I live we have air temperatures around 37°C right now.
When I normally use my DHD, it runs with battery temp at around 31°C, sometimes a bit more. But, If I put it on a windscreen inside my car, it overheats in few minutes reching more than 45°C which is overheting limit. All this means that I can't use my DHD for navigation, or for Blackboxing (DailyRoadrs Voyager, Autoguard).
I drive myy car daily for more than 200 kilometers, and I find my self in very odd situations daily, and if I have to prove my innocence having my drive filmed can help me a lot. Thats the reason I would like to use this blackboxing programs daily.
I was thinking to undervolt my DHD or set lower CPU freq.
Does any body have similar problem or maybe an answer.
Thank you for your reply.

Well if your dhd is in the direct sunlight inside your car it's normal that it's that hot and there is nothing you can do about that.
To lower the battery drain, and as a result the battery temperature, you can lower the screen brightness, or UC/UV your cpu. Those are the main factors of the battery drain.
Furthermore you can turn off the data connection while driving because it needs way more battery when you're driving

40 degrees Celsius?

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
Sent from my Galaxy Nexus using xda premium

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...

Battery overheating a lot (CDMA version)

My battery seem to overheat alot,its even uncomfortable to hold up to my face sometimes. Is this normal? The back gets very hot two.

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?

Just got it today... Temperatures though...

Well I just got mine today... Its FA44EWM... and its a fireball just like my M7. GSAM was reporting 109F when it was setting up initially. Couldn't even hold the thing.
Reviews said that it doesn't get hot at all so I don't know what's up with it. I'll use it for a few days and report back. Anyone else having temperature issues? I'm afraid its going to fry the camera like the M7 :\

I noticed my m8 got pretty hot when streaming video through the my dji quadcopter app. In normal use it does not seem to have any issues. The aluminum body is supposed to be a great heat sink.

I guess I'll just have to watch it then. I knew it was too good to be true asking for a Qualcomm SoC that doesn't have heat issues... At least its not the Sensation I guess.
I just ran a stability test with Antutu... Its actually not that bad although if it was on the charger, it would be problematic. Topped out at 108F/42C, started at 86F/30C
Other than that, everything is perfect on this phone. Not a single build quality imperfection, great LCD, surprisingly nice camera, and better signal than the M7 had. I don't regret it at all, the heat is just disappointing. My UAG Maverick will be here on Wednesday along with my 32GB microSDHC UHS-I card I got from Amazon for 25 bucks.
.

Mines has no heat issues. Only heats up during intense gaming, benchmarking, and for some reason it heats up when the battery dips below 20% but only to a warm touch except for gaming it heats up tremendously. Even with my screen brightness all the way up it doesn't heat up ridiculously. Overall it's fantastic.. give it a few days or send it back for a replacement.

Same here, I haven't had any heating issues, phone is always cool to the touch.

How odd... it appears to be settling in or something. I just did a run with Brave Frontier (a game which is a great way to overheat your phone) with it plugged into the charger and its at 102F. The One would be at 113F by now and no longer charging as a result. I think I'll watch it for a bit. I seem to remember that my M7 actually hit 119 when I first got it and then settled down to a normal max of 110 with it rarely hitting 113 on the charger.
If Brave Frontier didn't overheat it, nothing will. Brave Frontier actually has a dedicated question in their FAQ for LG G2s overheating and its overheated my Nexus 7 before and crashed more than once as a result so this is actually kind of impressive. I'll report back as I use the device.

I've seen 11x degrees while charging, streaming google play music, using the GPS, and running ingress all with the phone mounted on a sunny dashboard. My device is my car infotainment system so it gets used heavily in the car. It doesn't always get that warm but definitely warm to the touch. Eliminate a few of those things and it will cool down but I would still call it warm when playing a game. Unless someone tells you exactly what they're doing with the device you should take temperature reports with a grain of salt. There are a lot of variables and unless you make them the same you can't compare two different usage patterns. I'm guessing it would stay cooler if you kept the CPU and GPU underclocked but if you run them at their specified clock speeds the device will heat up. Simply checking e-mail or web browsing will keep my device cool to the touch as well.
