Hot cpu

I noticed when browsing the web that the phone quickly gets quite warm so I installed StabilityTest and TempMonitor from Play store and ran a Classic Stability Test, within 2 minutes the temp went to 55°c and after 10 min is was 59°c, anyone else having these high temps? Running on battery...

Ok, thanks, was that battery temp or cpu temp?

Sorry that was battery. After 15 mins, CPU was up to 55c, didn't go any higher.

I have the same issue with my HTC one S, while i'm using browser (internet, google chrome) or download something with network mode "Gsm/WCDMA auto" my phone constantly changes between HSPA and 3G connection and heating up to 45,5 C. At this time, the battery consumes 1% of every minute. This is a problem of firmware of radio module or something else?
Thank you.

is anybody else concerned with how hot it gets? It takes just a few minutes of browsing and playing around with apps to bring the temp from 26-28C idle to 35-40C when the entire backside gets really uncomfortably warm. did somebody have a chance to play with different units to compare if they all do this?

Yeah it gets pretty hot, but I don't think it's too much to be concerned about. I think it's just an effect of making the phone so thin and making the body out of metal that means it heats up pretty quickly. As long as it's not going over 60 degrees I wouldn't worry! And if it does, you probably won't be able to hold your phone anyway

During use, phone heats up to 41c/104f regularly.. this cant be normal?

Just web browsing over 3g for 20-30 min will heat the phone up pretty warm to the.touch. it also drains about 1% per 1 min of 3g browsing not even streaming. I'm still on 1.73 att. No apps in background and there is no idle battery drain. Is this normal? I'm guessing not brightness is set way under half

This happened to me only when I'm on like YouTube for a while but mine reaches like 110° F :-(

mine gets hot as well just by browsing. it is right on the bottom left of where the camera is

If I just check FB or draw something, this phone will start searing my thigh when I put it back in my pocket. This phone is definitely HOT(not in a good way...)

I have had 0 heat issues (can only feel it heat up while charging)
Maybe this is because I had the iPad 3, so nothing seems hot in comparison

mine only heats up when im charging and using it at the same time (playing games usually)

Maybe someone should make a poll because I'm having zero heat issues. Played few games the other day while waiting for my gf's OBGYN doctor to come in and check out our soon to be baby and we was playing for a good half hour. Barely any heat at all. Charging produces hardly any heat if any heat at all (noticeably anyways).

The highest I've seen so far was 41C while using wifi tether. Since I came from Nitro HD, which goes to 63C when voice talk on skype or gtalk, and makes your brain boil, this didn't bother me a bit...

Mine only gets hot when I use google navigation, which is understandable. It gets warm when I play hanging with friends, but in my experience that game spikes the processor the entire time it's open.

No heat issues at all for me, I tried to put as much load on the phone as I could to test this issue and all is well, it got warm to the touch but no more than any other smartphone I've used in the last ~6 years...

41c is not hot. My Atrix used to rocket up to 60-70. That was too hot. Think about it: 104 is barely warm enough for a hot tub. You can run a fever of 104 and be ok. Yeah, it's high for a person, but come on - dual 1.5ghz with a HD screen? They can't make that stuff make cold instead of heat!! Just saying...
It stays well under 50c. In my mind... *perfect*

+1. Put your phone on your leg and drive with nav on. Heats up like a griddle after a few.

Indeed it does! Thanks for the laugh also. I can't see that too many things would warm up the phone more than that. You are using the internet, GPS, and putting a heavy load on the battery at the same time after all.

I am coming from an LG Thrive and using GPS never got as hot as this phone or got hot as fast either. The only time it did get hot was if the sun shined right on it. I put my screen to never shut off and run google maps so that it would update to latitude. The HOX definitely gets very hot on a cloudy day when my Thrive would be just warm if that

Just so we're clear, good build quality will often make the exterior of a device hotter. This helps keep the all-important interior cooler. Having my phone feel hot while being measurably at reasonable temperatures is good! You must be careful not to base your opinion of the device's thermal management on subjective senses rather than measured fact.

Oh I don't doubt that the phone has better thermal management. I was nearly stating the fact that it gets very hot when placed on your lap and doing nav... Can't really argue that one.

And I won't argue the subjective notion of heat on your lap during nav! I know 105-110 feels pretty doggone warm (I had to check the temp to make sure it wasn't overheating), but if the exterior is only a couple degrees different than the interior...? That's good stuff right there.

My phone does seem warm to me now that i think about it but it seems to happen when it wants..
yesterday i noticed it would get pretty warm (not ridiculously hot though) when i would be on it for a few minutes (texting, tweeting, the usual).
but then today it was just fine. it was warm but not like it was yesterday.
not sure if i'm just not used to having a phone with this type of casing, (i had an Inspire previously and it didn't seem to get too hot.) i would figure a phone with a plastic or similar material casing would feel warmer compared to something like with a metal back (correct me if i'm wrong )

I don't think that this phone should get hot. It uses a 28nm process while being just a dual core processor. I think that the voltage might be higher than it should be. We need custom kernels and roms for this baby!!!

[Q] Is it normal for Nexus S to get hot in Hot Temperatures??

The temperature in my city is around 40°C.. But real-feel is around 42°C...Summer has just started and my phone is getting hotter than usual... However, the phone is not so hot in idle mode... Its around 31-33°C.. However, after playing few games or browsing for around 20-25 mins, my nexus s is getting hotter and hotter.. I can feel it in my hands... But still, the battery temp is showing 36-37°C only... I've never even seen 38°C on my phone... But still, I can feel the touchscreen is getting very very hot...
After opening the back cover, I began examining myself.. I noted:
The battery is not that hot
The sim area is very hot (I even started my phone without the SIM card, but same result)
The area beneath the camera and flash is also too hot..
The touchscreen itself is getting v.v hottttt.... I cannot play touch games anymore... However, the lower part of the touchscreen is absolutely normal...
When charging, the temperature doesn't goes more than 35°C... However, I can feel the back side is warmer...
2months ago, when the temp was around 30-32°C, I've never had this problem Everything was fine and running perfectly... Still now, everything runs smoothly without lags
I've never heard that touchscreen is hott... I've had many phones and my city's temp remains mild mostly... So, what could be the problem?
I am using:
Carbon unofficial
Marmite 8.5cm_bigmen
No over/under clocking
Vooodoo sound with +5db (Hardware highest)
Ondemand with cfq
Battery timings: 1.5day with normal use (4-5hrs of screen time)
1day with heavy use (6-7hrs of screen time)
Should I revert back to stock ROM?
Is there any IC problem?
Battery problem?
Processor problem?
Or is it normal for the phone to get hot in hot temperatures (42°C)???
Should I see a doctor?

Its normal dude. If you want to keep it cooler than don't keep the brightness too high.
One thing that can REALLY heat up my phone is playing games at 100% brightness on a hot day so try to avoid that.

No dude the same areas as you describe are the ones that can get really hot on my phone.

My i9023 gets really hot if i play games at max brightness, so now I avoid playing games.
And yes, it also gets hot in the processor area, not the battery.

Now, my phone is getting very hot while playing Asphalt 6 or even Fruit Ninja... Only the processor side (Top portion of touchscreen and its back portion) is getting hot... Battery is definitely cool (Not more than 38degree)...
What could be the problem? My processor has gone mad or what? I've even tried undervolting as well as processing speed to 800Mhz max... But overheating remains

My phone gets hot only when I'm on full brightness and a game I usually put it at half brightness and it never happens even when playing mc4

This is absolutely true. I have Nexus S since 4 months... There was no problem at all then.. everything normal and running fine and never overheated at all no matter what i play...
This overheating problem started few days back when I tested overclocking and overvolting NS
Seem's this is the problem..
I think I have roasted the processor and it will always remain like that.. I will have to sell it soon now

is it still over heating on half brightness?

It is... I am on 3% brightness...
Should I give a try to a new OEM battery?
Will it resolve the overheat issue?
Why is the processor heating up too quickly? Has I finished its life by overcloking it? Or it is a battery issue?

I went to the local market for some inspection of my phone. The person said that your phone is not giving maximum current and the charging ic is getting very hot and has to be changed... How is this possible? I've never had any problem with my phone like this... 100% charging was always OK for me

Heat issue ,is this normal?

I am running cm9(beast mode wifi calling one ) atm but I have a heat issue with my phone around the camera and speaker area where the phone is really hot but by the battery n bottom half it is much cooler.
is this normal for you guys? N gals? And even if I turn of the phone n it cools to 91 is shoot back up again

Sometimes I have this problem while charging my phone, it actually will not charge at all through the night. I think this happens when it is warm, because in the summer, the phone overheats in my pocket and dies out

That's a 'feature' of the ICS+ kernels. While 100MHZ is the minimum, if it's actually set to that, the kernel is set to go back to 200MHZ anytime it gets the chance. You can watch this happen if your scheduler/governor app actually updates on current min/max speeds. ROM Toolbox PRO, SetCPU, ROM Control, and CM's Performance controls all display this shifting, though with luck you can sometimes get it to stick at 100MHZ. It just takes some persistence.

The modem on the phone isn't very good.
It even happens on stock where if you go in and out of dead zones, it will "SEARCH" for network and become burning hot, so it's a common problem that happens year round. It's a great way to kill battery. That's also why if you leave you phone in a sock drawer, it's going to last longer than if it's in your pocket walking around.

I never got my phone to go into deep sleep when I selected ondemand (or maybe it was ondemandx). I would try a couple of the other governors & see if that would help.
Sent from my SAMSUNG-SGH-I547 using xda app-developers app

OndemandX gives me good sleep, but forces the phone to minimum speeds when the screen is off. That tends to cause issues if I'm trying to use GPS or music without the screen burning.
As to what will work best... that depends on unique your phone, its apps, any tweaks that have been made, and your specific combination of scheduler/governor settings. I'm a fan of SIO, but sometimes the tweaks make that (and deadline) stick at max MHZ, in which case noop is great. At various times, I go with any of the SA2-based 'intelligent' options (SavagedZen, brazilianwax, SmoothAss, or SmartAssv2) or the OndemandX/Conservative basic sets. The others have gotten stuck more often and tended to allocate more processor than I think it needs.

I've always had the best luck with smartassv2. I think it's a good tradeoff between good battery life and quick processor speedups in order to prevent lag, plus I haven't had the issue of the processor locking up while the screen is off.

That's usually the one I always fall back on too despite new ones all the time and everything, it's my default now on any ROM.

[Q] Nexus 5 gets hot

Hey guys, Im new to XDA but i have a quick question for all nexus 5 owners. Okay i was just wondering if anyone else's Nexus 5 gets hot. I remember my nexus 4 would get so hot i couldn't touch it. I haven't had that kind of heat from my nexus 5, but it is there and i do notice it. It gets hot near the camera on the back, and it gets hot on the front at the top of the screen. I have a CPU temp monitor running on my device to check if my device is running to warm. I found it averages/hovers around 50 degrees celsius. When i open chrome and do some light browsing it goes up to 60 degrees. So my question is.. Is anyone else noticing their phone gets hot? And does anyone have a cpu temp monitor running and could you let me know how hot your phone is running at?
Thanks

Mine gets hot after a fair amount of time of gaming. Nothing terribly uncomfortable, but noticeable nonetheless.

96439824 25
Yeah mine is warm after just 5 minutes of normal usage non-gaming situations. Not hot but warm. Its starts to get hot to the touch after 15 minutes of heavy usage (ie. Browsing, gaming, etc) . I don't know if this is worth calling Google about and having them replace it, or is everyone's phone like this and I just need to get used to it?

I gotta stop reading on this forum the more more I read about this phone its make me not want it does all the things my Galaxy Nexus does. too not while browsing the internet. Low speaker volume. No flash. Questionable battery life. Might go iPhone...smh

Chrome is the problem. Its resource heavy for no ****ing reason.
I've been using chrome and my phone doesn't work hard at all with the same amount of browsing and tabs I always have open.
So its not the phone. You can expect it to get warm when doing CPU intensive stuff. Gaming would be it. But not hot.

guess what. youre using a 2,3ghz quad core device, ots gonna get hot when you use it. and itll cool down quick when you arent using it. thats how its supposed to be, thats how it works.

Okay i think it might be chrome as well. When playing temple run, my device only got to 58 celsius. But when browsing on chrome my device went up to 68 celsius. So now I'm thinking its just chrome?

As the other person stated - Chrome is a resource hog and definitely is part of it. Fully utilizing Google Now with the voice search activated (*okay Google*) can definitely do it. Try Chrome Beta, it's much better.

Does it get too hot to the point it won't charge? That what pisses me off most about my g-nex

i think its normal for the 'warm' touch at the back, it doesn't get quite as hot as the nexus4 becuase of the glass backing
i use tempMonitor app, i get around 47c cpu temp when its warm
im running r12 franco kernel UVing to 920mV at 1.95max ghz

Im using TempMonitor as well. When under normal circumstances (i.e. texting, calling, etc) my phone is running at 45 celsius. But it gets hot as soon as i go online or play a game for like 3-5 minutes. Im sure it must be chrome then. I understand the gaming part and how the processor works, but i didn't realize chrome was that bad. Ill try chrome beta. Anyone else know what temperature there cpu'c are running at?

my cpu is anywhere between 0C and 89C, depending what im doing with the phone. its normal to get hot, especially when doing something taxing. itll get hot, but itll cool down fast when the work is done. thats how its supposed to work. anyone complaining that device cpu temp is hot at 65C just doesnt know any better.

Lol well thats why I was asking and looking through the forums on XDA because I've never experienced a hot phone before. Im coming from the moto x which never got above 40C. That phone wasn't a snapdragon 800 though. I just wanted opinions of if it was just my phone or if everyones phone was like this. And if not should i send it in for replacement.

I know that this is BS because my note 3 which has the exact same processor never goes above 38-39 degrees Celsius even if I'm gaming for over an hour. If you think 89C is normal you're crazy.

what i see in this statement is pure ignorance. human body temperature is 37C, youre telling me that your cpu NEVER goes more than 1-2C over human body temp, even while gaming? do you live in the antarctic?
your only saving grace will be if you meant battery temperature, not cpu temperature. 39-40C would be normal then.

It's very easy to get wrong temperature readings from sensors btw. Trying to find a good app that reads them properly is not.
Parts of the phone warm up quickly but luckily the bottom bezel area does not.
