Anyone else notice their G2 runs super hot in general? My friend with a Desire Z is able to daily use 1.4GHz...I have to set mine to on demand between 245 and 998 for it not to hit 38C+.
On top of that, my G2 gets about 40C when I'm charging which is certainly quite hot! Running Virtuous 0.7.2 w/pershoot, but it does this on Cyanogen and evil kernel as well.
Does anyone know of any disassembly shots/videos? I'm thinking I might take everything apart and re-thermal paste everything...
Thanks!

Eh... 1st of all... you're going to put thermal paste on the battery? The temperature reading for the g2 is the temperature of the battery.
2nd: I've never heard of a phone that had a heatsink on its cpu. So I don't think you'd even have a place to put thermal paste.
40c is totally fine btw.

Not on the battery! Although, that's an interesting idea...use the dry thermal pads between the battery and the door. I'm just checking if everything is getting overly hot compared to some of your other devices. Thought it may be the charging circuit having issues or something...or bad battery.
40C is fine though? At what temp do most of you have set for CPU throttling in SetCPU then? I have mine throttle to lowest when it hits that temp.

40C does sound pretty warm to me even if its while the phone is charging. I am OC'd to 1.4ghz and even when using the phone while charging, I hardly ever go over 37C.
My on-demand is set to 368/1497 and when temp>38C 245/768, although that profile never really comes into play as my temperature rarely gets that hot. Have you checked your running applications to see if there is something eating system resources? Reason I say that is because the only time my phone gets noticeably 'hotter' is after I have been playing Angry Birds for say 20+ minutes.
I wonder if its due to Variable charging currents/rates. I've noticed this is particularly problematic when i charge from say...15% battery. And yeah, Angry Birds for 20+ mins = toasty!

Hmmm, that seems a bit warmer than the norm. The thermal pad idea was a good thought though. But I'd suspect some modding to be done for it to work.
There's a very detailed teardown at http://tjworld.net/blog/htc-desire-z-tear-down
This is weird. I know a lot of users were complaining of heating issues with their SG2's. I can't complain with the current S2 I have on me. The temps never exceed to that extent where it becomes unbearable to touch, and the temps are usually maintained between 29 and 34 degrees Celsius. I heard from a couple of sources that the Blue motherboard fitted into the S2 has a temperature regulation sensor whereas the Green motherboard does not and many complain. whats stranger is that my quadrant benchmark scores never exceed 3400 (on the 2.3.5 firmware) and its really starting to becoming puzzling. Do I have a hardware defect? or is it something coming in the way from preventing me seeing the full potential of my S2?
A quadrant score of 3400 is typical for a stock SGS2.
lol, I forgot I was running a stock version. i guess those users posting up scores greater than 3700 have rooted their devices with some napthalene kernel, thanks for clearing this up for me. I guess im still a noob. is 34 degrees celsius normal?
^^ "napthalene" ?

isn't that the name of the kernel most folks are using? :confused
lol
It is just people aren't used to phones getting warm when they are using an app like a game. They then panic and think their phone is going to die and post about the phone over heating or getting too hot. If you can hold your fingers on it continuously that is warm not hot. Hot is like fresh cup of black coffee which is too hot to hold.

Yeah, and most users also overclock their SGS2. Mine for example does about 3400 when stock, but when overclocked (simple when you have root), will bring it to 3700 and above. I've hit close to 4000 in the past as well.
WIth regards to the temperature, that is the temperature of the battery. 34ºC is normal. It can go higher during charging (I've reached 44ºC), but I recommend not charging and playing a CPU/GPU intensive game at the same time as you would have two heat sources that the phone will have to deal with.
anyone notice that it get slower when the phone is hot?
i tested with quadrant standard when its hot i only get 2400 points and when it cool down a bit it get back up to 4600
it was done on a fresh wiped rooted stock rom

That's pretty normal for all modern cpus/motherboards. Internal temperature sensors have the logic to slow down the cpu if it's overheating, in extreme cases, shutting it down completely to avoid physical damage. I think it's called thermal throttling.

All of my previous phones (evo, evo3d, evo lte, epic touch) and this one would get pretty hot under one of two conditions - playing 3d games or browsing certain websites. When I say hot I mean about 90-105F. If yours is getting much hotter I'd be looking into getting it replaced.
Hello, I've had my nexus 4 for about a week and a halfish now and I've noticed that the phone is running pretty warm after even just light usage. I download a battery temperature reader and a CPU temperature measurer. At Idle the batter temperature is at about 33-36 degrees Celsuis. And the CPU temperature at Idle is usually in the lower 40's at idle. Are these Temperatures to high?
Also When I plays games or use any apps for a just a few minutes the battery Temperatures get at around 40 degress C and the CPU temp is usually around the 45-50 area. Again Are these temperature to high?
I would really appreciate if anyone could give me useful help on this issue I'm having with my phone.
Is this normal for a nexus 4?
Should I be concerned?
Should I get a new nexus 4?

I'm assuming your Nexus 4 is a newer one (rev. 11). Nexus 4s have been known to run quite hot. My rev. 10 is at 42 C coming out of sleep without use, earlier when I played Need for Speed, it got to 60 C. It seems to be normal for mine, although it does get uncomfortably hot.

completely normal. right smack in the middle of the range of normal. remember, human body temperature average is 37C or 98.6F. when you use your device, the temp will go up when you use a cpu intensive game, the temperature will get even hotter. this all also depends on the surrounding air temperature. the warmer it is around, the warmer the device will get or idle.
Normal. Because the back is made of glass, it absorbs the heat and you feel it more than other phones.

Lol My Nexus S get's warm on idle because of the hot air around. haha my nexus 4 coming in 3 days let's see!

Hmm, That seems weird, if the phone throttles you at 37 degrees shouldn't my phone not be idling at that temperature, and the my front screen seems to get warm after slight usage to. And looking on other forums people with a stock nexus 4 said that there phone idles around mid twenties, not the lower-mid thirties.

for hard working with QuadCore it s normal to get ~40 C quickly
But after 40C i think it s not normal and it s better to ask official service

look at the time they were posted. now its warmer eveeywhere. and again, human body temp is 37C. you have a quad core phone, it WILL get hot at times, that is normal. pushing the device, you might even see 70C or 75C.

Hmm okay I have pushed the phone and the highest CPU temp I reached was about 60ish. I'm not exactly worried about how hot it gets, it's just how fast it gets hot, it seems a little odd that just running facebook and twitter for a few minutes can get the battery temperature up to 40 degrees celsius.

That sounds similar to the results that I have found on the web, people said that to get there battery temperature up to 40 degress they have to push the phone, mine gets there just by opening a few apps.
If you want to cool it down and you are happy with messing about with your phone, try undervolting the CPU. Although I tend not to check the temperature, my phone (UVd by around -150) feels far cooler; playing Real Racing it doesn't get as warm as simple browsing would on stock.

I have heard of this, but I'm more focused on how the temperature should be on this phone untampered. Rooting and tweaking kind of scares me a bit.

Try faux kernel and undervolt t by -125 my friend using that combo and its mostly 25degrees.

40C is not hot. get that out of your head. idle temp will depend on the air temperature around you. yesterday was 91 in nyc, my phone was idling between 39-42C. stick your hand in 40C water, itll barely feel warm.

40 C is 104 F degrees, That would feel more than just "barely warm"

On a surface like metal it would, but not in water. That said, the back of the phone isn't water but I'm sure the temperature of the back of the phone is lower than the CPU

Couldn't agree more, The back of the phone I wouldn't say it HOT, but it is definitely very warm. But I'm not talking about how hot the phone feels. I'm trying to ask about the internal temperatures and if it's normal for it to heat up so fast.

again. this is normal. 104F would not feel more than slightly warm water.
the glass in the back of the phone is there to draw out the heat from the phone. its glass, and will feel warm. if you have problems with 40C, then i would recommend that you buy a dumb phone. my nexus 7, galaxy nexus, and nexus 4 all idle a bit warmer now than in winter. 40C is very normal.

With normal tasks such as browser, phone and messaging, the CPU temp of my phone is around 38-40. With tasks as YouTube and graphics intense games it's between 50-55. At this point, the phone feels really hot.
Are these expected temp level or is there some problem with my phone?
With asphalt, the temp averaged around 65C. While downloading the additional content it reached 75C.
I rarely see mine above 45. I've only seen 50 a few times. Throttling kicks in bad above 50

How can i check the temp of the CPU? Most of the apps don't even show temperature on 6P and CPU Z gives me like 15 different readings ;/
For this I had used CPU Temp. But yeah after the update, it says that it cannot determine the temperature.
In CPU Z, I was unable to understand the readings. One of the app, said that there is no temperature sensor to determine the reading of the phone. So not sure if we can get the accurate temperature.
But the phone is for sure getting too hot. I feel Nexus 6p has heating issue, or atleast mine does.
45-60 shouldn't damage your CPU, but 75+ can be harming for phone's integrated circuit

Remember that it will go up to 70°C maybe higher and the aluminium case spreads the heat making the whole device hot (LG G3 was very hot only in specific area, because it was plastic).
