Something Ive always wondered, what is an "AVERAGE" battery temperature for cell phones? I ask because im using setcpu and i never knew the temp. to start getting concerned . Right now it is 87.6 degrees with the low clock at 1ghz on demand at all times.

That is normal temperature. Once you use the phone (play games, internet, etc) it will reach around 90-100 degrees.

There are several different applications on the android market which will tell you the temperature of your battery in Celsius and Fahrenheit. That is about average temp, I have two phones sitting next to me right now and they are both in the mid 80's range on the temp. You want to be concerned if your battery reaches temperatures exceeding 101 degrees (Fahrenheit) (38 Degrees Celsius) when doing any activity and especially if it is getting that hot while sitting in standby.
I've had a recent problem with mine the other day I was having a really bad battery drain and the battery was over heating bad(im talking 105 degrees) since then I was able to fix what was draining the battery but I noticed when I use only my car charger (which was meant fire my vibrant) it heats up. I'm thinking the car charger voltage is different.

the highest mine ever got was 56C
i could have probably fried an egg with that
Mine stays around 82 while screen off. On and playing games it got up to 110.
So im using tbaldens cm9 and set the CPU to performance, which sets CPU at 1400 constant. So I was playing temple run for about 10 minutes and my battery temp got up to 50 degrees. I have a program called Droid system suite and it said my battery was overheating at that temp. My question is, what is a safe temp for the battery? And how long should that temp be maintained? Thanks advance.

to be safe don't let your battery temperature exceed above 50 c
below that temp its safe

So would it be OK to sit at 50 c for periods of say 30 minutes? It gets bloody hot to touch

As lithium battery exceeds their operating temperature regulary, it will impact on it's life. While working on overheating state, it may not able to provide stable/enough currents to the phone. Wrost case scenario == blow (ignore, this need really hot).

well i would say if temp reaches 50 c then leave ur phone for some time as it will affect battery life and also don't use ur phone while charging until the battery is charged more than 50% as many times while playing games at charging less than 50% our phone consumes more power than the power it is receiving

It gets to 50 c after only 10 minutes of game time. So you think 50 c for battery is too high? Should I stop gaming if it gets to 50? Don't really care if it uses heaps of battery, just don't want to damage it. Lol.

which game are you playing? i have played many games and none take me to 50 c in 10 minutes
may be u can try faux kernel to reduce battery temperature and which rom are u ysing?

As most of the smartphones now use LiPo battery, so here is a safety guide:
http://www.icharger.co.nz/articles/ArticleId/3/Lipo-Lithium-Battery-Safety-Guide.aspx
Wowza!!! That's hot!
All good, took it off performance mode and set the minimum speed to 475, seems to be not getting as hot now, where as I had it set to 1400 all the time and it would get really hot...

htc released a statement near to when the hox was released. it said that 55 celcius was normal and safe.
Yea mine is running under that most of the time on CM10 ROM. Playing 3D intensive games like Dead Trigger. Does get hot after quite sometime but not 10min. Good thinking with the CPU Speed adjustment, i used an overclocked kernel for a short bit @1.7GHz but that got pretty hot pretty fast so I have left that for now. Don't really need it on a quad core. Yet.
Mind to share? Dial *#0228# to show.
Here is my numbers(indoor usage) :
When idle: 24C to 27C (75F to 82F)
When general browsing etc.: 28C to 32C (84F to 90F)
When playing video or game: 34C to 39C (93F to 102F)
27C-28C idle for me.
28C-34C when just doing general browsing such as reading XDA.
35C-36C after about 5 minutes of light gaming (e.g. Candy Crush Saga)
Running Wicked v4 with included kernel, underclocked to 1674MHz, contained in a Neo Hybrid case.
Above temps while not charging. Charging temps are much higher.

Wow... I average between 75 and 85F (29-35C) under normal use/idle... I've seen up to 105F (40C) under heavy use or after flashing a ROM and the initial setup.
I think those temperature readings are for the battery. If you want to check the real time CPU temperature check out system tuner. Btw, you have to be rooted in order system tuner to access the temp readings.
Yeah i think those are their battery temp readings. My CPU has heated to over 70 degrees under heavy gaming, and averages 40's and 50's under basic usage.

+1 similar results here. Although just noticed the external thermistor reading from *#0228# is similar to cpu temperature but with lower refresh rate. It is on par with my idle temps but doesn't show real time hikes. So here are my external thermistor readings. While browsing on Wifi at room temperature, it is about 38-40 C and under heavy gaming it goes up to 48C (playing Real Racing 3 about 15 min)

If you are on stock rom it should work. Make sure to dial the exact *#0228#. There will be two temperatures on that page. One on top, which is the battery temp. And one on the bottom which is right under 'external thermistor'. I think, external thermistor reading is either the average cpu temperature or a sensor that is very close to cpu.

Yeah i'm not on stock ROM, but my kernel has a CPU temp reader that checks every second, and its currently at 44, under mild usage.
interesting stuff, I'm planning on buying a S4 soon
It makes me somewhat feel better knowing that mine is just normal like everyone else's.
However, this is really a too "hot" a phone for me. so I am dumping this one for something else.
It was fun ride, but it gets uncomfortable when walking with this little "heat radiator" in my pants pocket. For people having cold hands, it might be a feature, but, too bad, it is not for me. I might check out the Galaxy Tab 3 in few months.
Lol I'm running PAC man w/Chronic Kernel, Apex launcher.
Friday on one of the hottest days in Phoenix 116, in my car w/out A/C using I heart radio on my phone. The radio stopped, after a minute I looked down found it had rebooted it. So I went to the home screen where I have system tuner pro widget and the CPU temp was 200°F... oh crap, pulled battery out left it like that till I got home.
Got home the phone was still hot, so I put both the phone and battery in the fridge for 30 min. Installed the battery after retrieving it and the phone and crossed my fingers and made a prayer. Phone booted up and still operates as advertise:thumbup:.

From GT-I9505 Dial *#0228# I only see battery status and "quick start" button, so I used *#0*#, select sensor, select thermistor, "AP" column (= Android Processor Temp). Is that the same thing your looking to compare?
At boot: 31C
Idle: 36C to 37C
After 3min video playback: 45C peak
My average CPU temp is 34°C (93°F), and I go up to 67°C (152°F) when I play games (like GTA-VC).
Do you think it's normal that kind of temperature from the S4Pro ?
Actually this is really low...
67c on high load like games, which stress the cpu?
My device goes to 80c easily, starts to throttle cpu speed and shut down cores, all of the devices do that. This temps are normal.
By the way which app you used to measure that temps?
If you really want to see how your device holding up,
Download that app:
https://play.google.com/store/apps/details?id=com.into.stability
While run the classic Stability Test measure your cpu usage and temps.
Personally I use FauxClock.
After a few minutes you'll see the high temps and the cores throttle.
Oh, joining this question. Just got a 32Gb LTE version and found out it's getting quite warm when playing something like Osmos, Doodle Jump or something. I don't know how to get the exact temperature, cause monitors I' found on market, show only the battery temp. Anyway who else gets his N7 warm/hot when some heavy app is running? Asking, cause my friend also got the same N7 and I don't remember it to be hot even after running 3D games for quite a long time.
I used the app "System Tuner" from gplay.
Apparently, your StabilityTest app requires more power than GTA-VC, I recorded a 82°C with a 50mV undervolt (on Franco r3 kernel) after a 8min StabilityTest, then I just stopped it. I'm a little afraid of this kind of temperature :/ Are you sure it's okay ? I don't know well the mobile device world...
That's the real temperature , even higher,
And you don't need to worry too much.
Your device will turn off if the CPU reaches too high CPU temp,
And 80-90 c is fine. The soc is built to work on that temps.
As you could see your CPU shutdown cores and lower cores speed while the temperatures going higher, that's called throttle.
You don't need to worry too much.

StabilityTest can load all 4 CPU cores 100%. You won't find a game that does that.
The CPU will be thermally throttled (clock frequency will be limited when the temperature is too high), so you won't damage anything.
And is the average temp of 45-50 °C normal? I'm just using Skype and surfing the internet.

If you run a adb logcat while gaming you start to see alerts going off for high temperatures when it gets around 70°c or higher. I found it very interesting that it was alerting when it got that high instead of ignoring it like you say till 80-90°c.

Games use GPU which adds much more heat to the conclusion.
Stability Test don't.

The device doesn't ignore it till 80-90c. It's start at 60c.
I just say that it's safe temp for the soc to operate. Which means your cpu never use all cores, and the cores that active wouldn't be at the highest speed, while the cpu reaches 60c, more heat more throttle.
Ok thanks to all of you, so it's like computers : if it's too hot, it will stop before it reaches a dangerous temperature.

Those are quite ok. If you include skype with voice/video calling ofcourse. I just get about 30-40 with just surfing and chatting facebook messenger skype/yahoo/viber on background
I'm fairly sure the CPU tends to downclock itself not because IT is getting too hot, but because it's generating too much heat for the battery. Almost all CPUs can easily withstand upwards of 80C. Batteries, on the other hand, can't.
I have a POCO F3 and I know that it's normal for the phones to get a bit hotter while they are charging. I noticed that my phone while charging can get a temperature of 40º celcius, then the temperature comes down gradually I believe. When it's not charging, it's usually between 20-25º celcius. Is this normal?
Phone are supposed to heat up while charging (especially Fast Charging "33W"). Normal human body temperature is around 37c. So your phone is pretty safe on 40c while charging. But it isn't if it is on 40c all the time.

It's only when it's charging. I've noticed that the temperature decreases when it's approaching 100%. When it's not charging it's usually between 22-28º celsius

Ok, thanks for the help!
This phone uses fast charging till 90% and after it slows down. That is the cause of temperature decrease when it's approaching to 100%.
I used a slower charger and only a fast charger in emergencies, heat and electronics don't play nice.

The faster the charger, the higher temps, therefore more battery degradation.
However, 40°C is still o.k. I think. I think the advantages of using Fast Charging are bigger than the disadvantages.
Keep in mind, the biggest battery degredation comes simply from age.

Never use your phone with heavy tasks / call / gaming ... while charging : not only the heat will damage your battery, but this can explode, especially in hot environment !

The disavantages are bigger than advantages :
. heat degrades battery faster
. explosion risk still exist and is higher with fast chargers
. heat not only damages the battery but thermal paste in the motherboard and the storage ... you will notice lag / data corruption after 6 months no matter what you do/update the software !!!
I use only old chargers 5v/2a max ... even if my devices are modern and support fast charging !
Fast charging is a marketing trick to force consumers buying new phones in a short period while your phone can last more than 4 years !
Bad software/kernel optimization is the main culprit for fast battery draining.
Age/ Time : NO ... my Redmi Note 4 (mido) still holds (after 4 years) its full battery capacity and i can reach easily 9 to 10 hours SOT. (i use self compiled lineageos)

I think you are a bit overprotective. Explosion Risk? Come on. I know it can still happen, but it's so rare.
Yes generally heat causes Battery degradation, but it also depends on the phone and how good of a job the manufacturer has done.
10 Watt Charging is really slow man...
I also don't think it's simply Marketing, because Batteries have also gotten bigger. We went from 3300 mAh batteries, to 4500 mAh batteries in many phones nowadays.
Chipsets are also getting more and more efficient through 5, 7 nanometer-technology, however the increased clock-speed (and other stuff) outdoes that mentioned efficiency-improvement.
I really understand your concern, but don't you think it's overprotective? 10 Watt is really slow in my opinion

Don't forget the heat generated by the modern cpu/gpu ... so yeah add this to the heat generated by the battery itself !!!
... and don't forget that smartphones are closed environments for the electronic components (some manufacturers add fans for heat dissipation and they know why they are doing this) !
I don't care about slow charging since ... i remove the sim card and put it on another phone while charging.

So should I buy a slower charger? Or can I keep this one?
gringo80 , I agree with the things you have mentioned. I have only one doubt, does the use of slow chargers with the new Mi 11x will support it completely and doesn't have any side effects?
In Layman's language, slow charges can be used with today's generation Android phones?
