nexus s getting very hot

i have a nexus s, 4.1.1, original clean update from google.
the phone is getting very hot while using it.
for example when i use internet radio with the screen off its gets very hot,
when i have a call for more than a few minutes with the screen off its hot too.
it's not the problem since i upgraded for jellybean, but it was a problem since gingerbread
so not JB's causing it.
any thoughts?

I normally have this problem with certain kernels. If you are rooted try thamulus kernel as I have no issues with heat.

Mine is getting hot too since I use facebook for a while (30min) or just searching Internet around. In my case I'm using custom Kernel without OC.

try to change the kernel
here is the latest AIR kernel download link

How is the battery consumption with the excess heat?

Check your battery, I am a certified Service and Repair tech and if the battery is shorted, it will generate a ton of heat. Pull your battery and if it is bloated even the slightest, replace it. Unfortunately you could smoke your phone running it too hot.
Also, are you running any custom UV or anything? All devices handle voltage changes differently and if the kernel you are using has custom voltage settings you could be running into an issue there as well.
Hope this helps.

checked the battery, looks like new.

When using your phone, it might get hot. The cpu, screen, wifi, gps, bluetooth generate heat when you use them so there is not necessarily a problem with your phone/battery.
However, if there's a problem with your battery you should replace it because it could damage your phone. I suggest that you download an app that tells battery info (temperature) and post them

37*c its ok temperature for battery ?

[Q] High CPU Temp (70 C)

Hello All,
I just got a LG Nexus 5 a couple months ago- I ran stock for the first several months and loved it, but wanted to take advantage of the services provided from custom ROMS and change-up the look of the stock google UI.
I made the mistake of not testing various things with the stock ROM and kernel for reference against the custom software I've installed- so I have no idea of how my phone was "running" before I changed it up. (Benchmark scores, CPU temp, Battery life, Battery Temp, ETC)
-so I have no idea if my phone was acting like this before I rooted.
TLTR-
In my FKU app I've enabled CPU temp monitoring and have noticed that this thing is running at rediculous temperatures:
39-43 Celsius when in pocket
45-55 When Browsing Web/Facebook/Snapchat
55-79 When playing 3D games (Giant Boulder of Death) or Benchmarking
THIS SEEMS DANGEROUS.
Apart from the slim chance of a small electrical fire igniting in my pocket whist on my way to get a burger, I'm concerned that my CPU is going to burn-out on me!
I've browsed these forums quite a bit and have seen (somewhat) similar threads about heat problems- but none pertaining to CPU overheating specifically.
I should probably add...
Currently Running:
Android 4.4.2
SlimKat 4.4.2 OFFICIAL-3080
Franco Kernel r37
Updated Bionic & Dalvik libraries
Has anyone experienced anything similar to whats going on with me?

These temps are fine. Your phone has a safety shut off at 99 and honestly there are some of is that turn thermal throttle off and hit that limit during benchmarks very regular. 79° isn't anything to worry about, your phone is fine. If it bothers you that much use FKU app to lower your temp for the thermal throttle but there's nothing to worry about here. Just ask @simms22

I get around these temperature usually too. When on the wireless charger it overheated so I went back in kernel settings and put thermal throttling back to stock
If you're running a custom kernel I'd recommend keeping with stock thermal throttling.

Hi,
Nothing dangerous, normal to have some heat with a quadcore CPU running at 2.26 Ghz, enclosed and without any hardware thermal cooling.
This temperature is "normal" while playing heavy games (3D games) or while benchmarking.
In any case there is a thermal protection, thermal throttling and in case of extreme heat: shutdown. This CPU can go at 100°C before shutdown so...
You can underclock or set different thermal settings with Franco kernel.
There is already a bunch of threads about that, even about CPU temp, read them closely.

yup, very normal. if those temps are too warm for you, use your phone in a freezer or just stop using the phone(just kidding). but yea, youre fine with nothing to worry about.

It should be noted that it'll actually start to automatically downclock itself after it hits 70C in order to maintain thermal integrity. Many, many phones do this, that's why long term benchmarks start off really fast, and then slow down.

If I remeber well ICs can work without any damage till 120 C

I´m using kernel adiutor to prevend throttling. Before I did that indeed I´d get throttling behavour on the phone.

Define "overheating", as in the actual battery temperature. Not "it feels hot".

That doesn't tell us anything. Get an actual battery temperature reading, not what you think it feels like. Most kernel apps should tell you.

I don't pay attention to it myself since I know it isn't overheating. Various kernel apps should give you a reading, hell even Antutu Benchmark tells you your battery temperature in Device Info.
Also, when your battery reaches 60C (or 65C, forgot which of the two), your phone will force shut itself off. Chances are, you're not even feeling much heat from the battery, the CPU usually produces more heat before the battery can even reach that high (some kernels have battery shutdown disabled anyways). The CPU starts throttling at around 60C CPU temp (NOT battery temp), and force shuts down at 105C. Clearly, "warm" is no issue at all.

Overheating

My opo overheats without any heavy usage, I don't play any games.
I was on CM13, Darkobas rom and now Candysix rom but it still overheats what can I do?

Hi,
Have you tried a clean fastboot flash ?
Or can you upload some screenshots from an app like "CPU temperature" to see how is your overheating ?

Why you say that is over heating? Post some as about CPU and battery temp

This after ~15 mins of easy usage (battery temp. on status bar)

i don't this that these tempreture (48) is high...

So does anything happen when it starts to over heat?
Over heating to me would be 60s+ that's normally when the back of the phone is feeling very warm.
After I install a new rom, start up is rebuilding the cache and I've got it charging that's the only time I notice a hot back. Or if the GPS and 3g might be doing something strange.
If your phone is slowing down then look into it. If it seems fine but you just think the numbers are high then I wouldn't worry to much.
Where do you live? Is there a lot of direct hot sunlight?
Do you have loads of apps installed that might be misbehaving?
Or pick a rom that is slightly underclocked. Running it at max speed does make it warmer. Sultans kernel normally runs nice and cool. Think darkobas also uses it.

I used my opo for ~10 min I was on facebook and listening to music and my opo was around 38C that is not normal
I flashed CM12.1 with Sultans kennel but it don't seem to help, I live in Sweden it's around 25C but it overheats even when I'm home

That temperature is completely normal during use. If it was 80c then you can claim overheating, which it clearly isn't.

Overheating

Hi, 3 day ago I recieved my Mi4c (3gb) and just after couple of minutes surfing on the net I realized, that the top of the phone is really hot (the bottom was normal). The next day I tried it with game - after just one or two rounds (about 2 minutes) phone got hot again - again at the same area. I downloaded some app and I looked at the temperature after running the game - it showed even 55 degrees Celsia. Is it faulty piece or is it just software issue, which can be fixed by different ROM ?

Under load, the SD808 can get pretty warm.
Add to that the fact that MIUI (in all of its various forms) is a steaming, overheated pile of rhinoceros feces and you have a terrible combination just asking for heating problems.
TS CM13 does a pretty good job of mitigating the software issues that lead to heating.
The phone will always get warm when playing moderately intensive games or when used in direct sunlight on warm (30c+) days.

I found that the miui versions some vendros provide are manipulated or corrupted by vendors,
I suggest you check if your bootloader is unlocked, install a recovery, do a total format (not a factory reset, a full system format from recovery) and install the latest miui,
I had overheating issues and the phone would eat the battery away in less then 12 hours, i did this and im currently going on 39h standby and around 1 - 1.5 hours screen time and i still have 34% of the battery life.
Clean house, start from zero and you might be surprised.

Just installed MIUI 7.1.6.0 Global stable from xiaomi.eu and I like it more tham MIUI 8 already. Plus, phone seems to be a little cooler. Snapdragon 808 is still a hot chip though, so don't expect miracles.
Switched from MIUI 8 because of heat and battery life issues.

I tested different rooms and every room has overheating. The only difference is the time the systems downclock the CPU.
In cm13 I changed the values so it doesn't close the big cores so fast.
But the big cores are still the most time off.
Normally my Temps are between 40 and 60 °C
And that's bad.
Miui doesn't change anything.. Only the time of throttling.
I don't need a phone that throttles itself when turned on.
When I'm home I'll try to open the back cover and take a look.
Maybe I can hard mod it in some way.

I'm facing the same problems here.
I use dual Sim, so I thought this could be the signal usage. But my battery is draining faster and faster. Some times even dropping from 14% to 10% in 1 sec!
When using wifi, the cpu reaches over 50ºC (currently 57-59ºC). MIUI 8 didn't help much.
I'm using my phone a lot, 3G and screen on for long time, but it's dropping from 100 to 15% in less than 7 hours...
Is there anything that I could do?

Install MIUI 7.1.6.0, temps and battery are better, or go Apollo the way and flash CM13 or Slim

I have over-heating problem too. Specially by keeping screen on for several minutes. I'm on miui 8 by xiaomi.edu

The overheating is caused by a ****ty rom some vendors use,
Install the latest recovery, and do a full advance wipe (everything except OTG USB), then do the format,
DO NOT REBOOT the phone, connect it to the PC and copy over the latest miui weekly (i used 6.9.1) and flash it, then see if it keeps overheating.
Apparently some of the malware some vendors install are hard to get rid of, i had weekly, monthly, slim6, Teamsuperluminal and Omni rom installed, and they all showed the same issue. it wasnt until i did this "sanitation" process i managed to get rid of the heat issue.

You found some way to hard mod it ? =) The snapdragon 808 would be very powerful if there aren´t that overheats.
Making some holes in the back cover (get out hot air) or give more space (case is extremly tightly built) ? A heat pipe (passive cooling)?

Things are a lot better using an undervolted kernel. Built one from kuma sources (not for MIUI), I could share if you want.

nice idea with passive cooling
i glued my nhd 14 to the back that helped
no serious i dont have any clue to make the phone cooler with hardware modifications.
without the backcover it isnt cooler. the difference isnt noticable.
i would say how the cpu is build into the phone is wrong.
for me the phone isnt worth it anymore. im moving to a BQ or the HTC10.
why should i use a phone that i have to downclock to a fraction of its performance ?
or i use normally and get throttled after 20 minutes?
and it doesnt matter which os i use any miui or cm version suffers from overheating.
so i think ether xiaomi make mistakes while building the phone or it is just the bad 800 series.
but looking at the lg g4 the picture is the same. so qualcomm is to blame for it.
sorry for this but the only solution is to use a fan on the back OR the better solution buy a better phone ;(
edit:still finding grammar fails

For anyone willing to try this is an undervolted kernel based on kuma's sources and a modified msm8992-regulator.dtsi with lower ceil voltages.
Tested only on CM13 but should work for other ROMs based on CM13. It can make your phone unstable (freezes, crashes), so before you try either keep a backup of your current kernel or simply boot (don't flash!) the kernel to ensure that everything works normally:
Code:
fastboot boot undervoltedk.img

@Ydraulikos
im already using a kernel from kuma (Resurrection Rom) and yeah its very great, less overheating. The Rom itself is slim for less heating too.
But its overheating though while playing 3d games for a longer time.
@kar5ten
..nhd 14.. that would look funny xD.
Yeah the problem is the cpu. Snapdragon 808 and 810 suffering from overheating, 810 more.
But xiaomi could handle this too. Not use this cpu or built better cooling system, instead make it as thin. The most temperatures i have is on the top right. If they used passive cooling like pipe heats for distribute the heat, we don´t have this problem or rather less overheating.

@Ydraulikos thanks i will try this.
@Danny94
i made another test.
i use resurrection rom 5.7.1 with oc kernel 1.12 (intelliactive gov.) custom temp. throttle at 75 C
i opened the back and added aluminium foil .
10 layers on the upper side where the cpu sits and 6 layers above the battery and the cpu. they both are connected.
now i run antutu 3-4 times and i got these results
75899-74012-70371-68155
with max temp of 53 C after those 4 runs.
the idle temps are now at 30 -35 C most time
but i only tested it for 2 hours

@kar5ten
oh nice that sounds like a good idee! And withouth foil wich results you get, antutu - temps ?
The Alumiunium foil could take the heat from the cpu and distribute it over the device, for better result thermal paste as connection between cpu and foil could help.
Maybe with another material (foil) you could improve it as well. The best result you would get maybe if the backcover consists of metal, this way you could get the heat out of the phone, air cools metal. (problems.: back cover can get hot, you can heat back cover with hands[maybe a case])
Care about that foil doesn´t heat up the battery and the metal can disturb radio signals (gps wifi mobile data).
Could you share a picture as well of your modified version here in the forum, maybe one too please how it looks inside. At the moment i don´t have a plan how to open the back cover. =)

I will post some pictures but next weekend. Before I open it again I want to test it.
I don't know the exact results from antutu before I modded it.
First 75k
2nd 60k
3rd 55 k
At the moment I didn't noticed any signal drop or something.

Hi,
Did you have the opportunity to take some pictures of your mi4c modding?
would be also great to have a slight bigger case it probably help with the overheating.
