A number of people have had their phones get very hot and wonder, how hot is too hot?
The purpose of this thread is to answer that, as well as be a reference that can be linked to for providing a quick answer.
Before anything, download a temperature app so you can see exactly how hot your phone is getting.
Once you have that, continue reading.
People have reported phone temperatures being a hot as 100° f to 110° f (~38°c). That is hot but not that bad. Upper 40's celcius (47°-49° ) is not good. And 50°c is critical And can cause damage, even though 70°c is considered the 'kill' temperature for lithium ion batteries.
There are many reasons this could happen. The majority of people notice it after flashing a custom rom to their phone. This has been reported happening in many forums, not just this one. On the whole, people find that when this does happen after a flash, it usually occurs once or twice, and then does not happen again. There is no clear explanation that I know of that can explain it. It could be the phone 'relearning' or adjusting to the battery. It could be an app that is not working well with the new rom. That is why rom developers will sometimes say to not do a titanium restore on all but your most important apps, and to download the rest from the market. It makes for less chance of an app not working well with the rom.
'Rogue' apps are many times also to blame. A rogue app can be described as a malfunctioning app that is improperly working and as a result causing high CPU activity, which in turn causes the phone to heat up. It also can be a bad app that should be avoided, at least until the issues it has are worked out.
How to fix that is usually on a per phone basis, meaning most cases are unique, and what works for one may not work for another.
There are apps that can help track down the problem app. One of the better known apps is better battery stats.

Check here for a better explanation of it and how to understand it:

It has also been noted that using internet browsers cause the temperature to rise roughly 10°f (5°c). So if your phone is running hot, stay off the browser, it'll just make it worse.
However, while you're trying to figure out what the problem is, your phone may be overheating, or at risk of overheating. And a quick way to shorten the lifespan of electronic is to be too hot.
The first thing I recommend doing is downloading SetCpu.
https://market.android.com/details?id=com.mhuang.overclocking&hl=en
Once you have it, or a similar app, downclock the CPU to 500mhz, at least while charging it, to help keep the temperature low in case an app spikes CPU usage and you're not there to stop it.
Sometimes even flipping the phone so the back is exposed is enough to cool it down.
Keep in mind most electronics have solder that will melt between 120° to 180°c (248 - 356 farenheit). While your phone should never ever get close to that, 50°c pales in comparison. But it can still damage the battery.
I also recommend SetCpu as you can setup a profile for it to run your phone slower when it hits a certain temperature to help keep it cool. As well as sound a notification that it has past that temperature.
Charging your phone will raise the temperature of your battery, it just does. At times it may feel very hot. But again, use an app to see exactly what the temperature is. It's not uncommon for a phone to heat up to over 40°c while charging. Though 39°-42°c is towards the high end of what is acceptable, it's relatively normal for charging temperatures.
For my phone I have a SetCpu temperature profile set at 44°c. I'd rather catch it before it gets even close to bad.
Feel free to post about apps that have helped you to narrow down a problem that is causing your phone to get too hot. As well as any experiences you've had with overheating and the steps you've taken to stop it.
For some reason, I've pinpointed browser use to cause my phone to get EXTREMELY hot. I've tried several different browsers, all with the same result. I will download a temperature app and report back.
UPDATE: I had just been using various apps on my phone for about 30 minutes, and the temperature was at 95 degrees. I then used the browser for 10 minutes and the temperature jumped to 104.
What browser? Dolphin browser has been reported by a few users to cause high cpu use. No cause was pinpointed so far.

Just played one race in Asphalt 6 HD and phone was wicked hot, did not have a temp app to check actual numbers.
What temp app you recommend?
Battery indicator pro is awesome. One of my most used apps. Data pack is almost done downloading for asphalt 6 on my phone. I'll post what temp it gets to.

Just played asphalt 6 and dang it's fun! My phone is running the latest unnamed rom, entropy512's 1212011 kernel @1.2ghz max, wifi on (though looks like juicedefender shut it off during the game, could account for the game crashing) , not plugged in. Game ended up crashing while running the kernel on conservative. Changed it to ondemand and had no issues.
Before starting the game my phone was at 29°c

Played one race with the mini cooper. Immediately exited and phone was running at 36°c
Not too hot, but a definite jump. As good as the game looks and as smooth as the gameplay is, I'm sure the temperature will need to be watched as with most high end games. I'll report back if I see any temperature spikes.
Update: played 5 races in a row and got warm, but not too warm, 41°c
Final thoughts:
Buy this game!
And xda app gave me two choices for quality on the screenshots I posted but wouldn't let the higher quality one upload. Said incorrect extention.

Mine has been getting hot lately too. I haven't identified any battery drainers as the cause, but when my phone gets down to around 25% batter lice the phone starts to heat up. Like today, I pulled the battery at around 20-30% because it was getting warm, waited about 10min for everything to cool down, put the battery back in and it was down to 3%. Either something we're running is causing this or there are battery issues starting to develop.

I did not, i was concerned about damaging the phone. I will the next time around. Thinking about buying a new battery to see if i have the same issue.
Use cpu spy. My phone does the same thing. Occasionally it gets stuck on 1.2 ghz, and really heats up.
Pulling the battery resets it.
I haven't been able to figure out what does it.

Hey everyone...
So today while i was trying to download an app, my cpu temperature became 63C (145F).
I was wondering if this temp is even possible and what the temperature the phone is set to turn itself off at.
EDIT: Moto Atrix btw, tegra2 processor
I'm not sure about a mobile processor, but a desktop processor can well above 70, 80, or even 90 under heavy load.
63C sounds wayyy too high for a low voltage/power mobile cpu. Then again its hard to say, as the mobile chips are passively cooled.

thats your battery though, i am talking about processor.
I wopuld assume that this temperature is damaging to phone itself, i just wonder what the overheat level for the nvidia tegra2 is.
hmmm, still very intrigued. part of me wants to runn my phone as hot as it can till it over heats and reboots, and part of me is saying im a dumba** for even thinking of that, lol.
EDIT: just wanted to say im running greyblur, if that affects anything at all, lol.
Haha, I guess I really don't know much about mobile hardware then ^^

I probably know more for hardware than software, don't feel bad, lol
But, actually, overheat status isn't true overheat function. When there is a true overheat, the phone either turns off or reboots itself. When the battery becomes too hot, the processor ignores that in most cases, while if the processor itself gets hot, it shuts itself down.
Yay, my first true member post, not junior anymore!!!! hahaha
I am also getting these high tempuratures on my cpu and not my battery.
My idle tempurature lowest was 35C and averages 55C and my highest was 70C and averages 65C. I really need help on how to fix this. My battery temp is around 40C
I set up a SetCPU profile so that if the CPU temp reaches 60C, it will max out the processor at 750 Mhz. For me, it pretty much cools off instantly. You may want to set yours lower. It doesn't reach that level often.
I've started a thread early today regarding the atrix's heat issues. Soon as I started playing games on my Atrix I got pretty scared with the temperature I felt on the exterior, and more scared after using temp. monitor apps.
http://forum.xda-developers.com/showthread.php?t=1249757
The idea is to mod the phone to help dissipating heat. Besides undervolting with setcpu I guess there isnt much that can be done at software level to reduce the main chip's heat.
The ideas are still being formulated. I opened the thread so I could get some help and suggestion from other atrix owners, to have a good idea of what to do when I finally open my phone
If anyone wants to try it or have any ideas, please comment there!
WolfFX, your link has actual "...." in the URL and doesn't work.
Regarding maximum temperature before shutdown, I'm wondering if anyone has EVER seen their phone shut off due to high heat? Does it even happen? I'm not meaning reboot either, but actual shut down to cool off.

Guys, I will repeat this just one more time. DO NOT let your CPU temperature get higher than 50C... Constant minor overheating causes long term damage to your phone, shortens it's life span.
One major overheating can toast your phone just like that.
These aren't desktop PCs, use common sense. Overclocking to higher than 15% doesn't come unpunished.
Also posted the same in the other operating temperature thread.
Did a bunch of looking around and after a while found some white papers with the following temperature ranges:
General operating temps of -40C to +85C.
Practical usage will start to drop off below -20C and above +70C.
This tells me that our safe operating range should be limited to the practical usage temperatures. Anything outside of these and there is a good chance you will see performance drop off fast, and also may suffer hardware lockups, etc.
Personally I will stick to +65C which is the rule of thumb I go by with my PC's under full load.
<edit> I would also add that while our phones are not desktops/laptops/workstations, the CPU's can all handle around the same temperatures in all devices. Materials used and manufacturing techniques are almost identical. The solder used has a melting point of around 180C - 190C, so there is no fear of melting the solder. The main difference is that phones do not have active cooling, so you will see much larger jumps and swings in temperature. This being the reason you cannot OC in the extreme ways you can with PC's.
i read a post somewhere that 75 degrees c was the max it should go to, anything higher is way too much
I read somewhere that if you overheat yer phone it eventually breaks. Pretty much it. Just don't let it out in the sun too long or anything silly. However, keep in mind that if you do break your phone, you can always donate it to XDA. I think they're looking for bricked and broken phones.

Mine gets above 50C, and usualy around 57C, every time I open any kind of game... Should I be worried?
when i used my phone to play cricket game within 5 minutes it got hot near the camera and i couldnt continue playing the game. I was totally puzzled. Also when i speak a long call for more than 20minutes of continuous the same heat is felt near the camera. Why is it happening. What is the remedy for this? I really feel bad when it happens
How hot did it get?
Why couldn't you keep playing?
Most likely the temperature isn't hot enough to cause problems but I'm surprised search couldn't help you.
Sent from my GT-I9100 using XDA Premium App
its is so hot that if u keep on playing you feel that u may burn your fingers placed over the camera region and the heat transfers to the whole unit as well.
might be an idea to underclock to 800mhz
I must say that playing PES2011 or Reckless Racing for ~15 minutes makes SGS2 really hot. Not hot enough to "burn your fingers", but it's still hot. Elixir says that battery temperature after play equals ~41 Centigrades, so the GPU is about ~60, 70 maybe? Can't check it, dunno how.
Does anyone else have that problem?
Same here, i played Order and chaos for about 6 min and it got extremly hot, so i quit and went to set cpu where i saw temperature was 51ºC...
However, i usually have it underclock to 800mhz and theres no heat(max. 31 i think), but i havent tried to play at 800mhz, i always overclock it to 1200 minimum for playing HD games and still do little stops sometimes while playing...

If you guys are playing at night time under low light conditions I suggest you get the App screen filter. It reduces the brightness below the lowest brightness settings that the phone can offer. I have noticed a big difference in gaming as my screen doesn't get hot anymore, only the back which is better than nothing.

Same Problem
Same problem here. Phone gets really hot around the front and back cameras, while playing games like RF11 or Asphalt6. Should I return it or flash a custom rom/different firmware. I am on XWKF3.
Same here on gaming..
The maximum battery temperature I've seen was 55 C while charging the battery, a game (Gangasta on message that data was downloaded successfully via Wifi) got stuck in background consuming a lot of CPU (~50%+).
Sorry guys, this phone as a severe design issue and the temperature problem can't be solved. You only can keep the cpu clock down.
He guys,
It's not only with playing games. My phone was doing nothing and the temperature raised (don't now the temp. but very hot) and the phone shut down, and was completely dead. Could not start it up. Could not charge it, because I thought it was empty. After cooling down, I took off the back and replaced the battery and I could boot it again. I was using internet 10 min. before. I think the cpu's where max. and getting hot. This is a serious problem, and I don't want to root my phone to clock down cpu. I am not a gamer so thats not a problem for me. First time this hapened in 1 1/2 month.
I feel realy bad about this. Did it shutdown because of the heat? Is there a safety thing build in? Is it damaged?
I' m wondering how the guys with overclocked devices cope with the heat. I have my phone only 5 days and it already crashed few times while playing games. Once it was getting hotter and hotter and it wasn't responding. i was worried so I had to hold the power button 10 seconds to turn it off. Maybe you(Frank-HTC) had a similar situation but with an app that was working in background?

Update your ROM.
I flashed XXF2 and it does appear to be running comparatively cooler now.
Sent from my galaxy S2
Had a similar issue - the phone used to get quite hot while playing games.
However, Samsung seems to have fixed this issue (at least for SGS2 India users)
I can confirm that updating the stock firmware (KF1) to stock KF3 has solved this. Intense gaming for 2 hours straight, with Wifi and lots of processes running, the phone is only mildly warm.
If you are experiencing this issues, please try backing up your data and updating your firmware via Kies.
My phone doesn't have this issues, I'm using a water-cooling system now.

Thanks in advance!!
Please use the Q&A Forum for questions Thanks
Moving to Q&A
A few rogue apps is what this sounds like, identify them and either delete or freeze them with titanium backup.
See what process is hogging the CPU. If it's media, you most likely have a damaged SD card. Had to fix one so I know what a horror it is. If that's the case, just run a bad sector scan from Windows or your OS of choice.

Hi,
Thank you all for the replys.
The phone was in my pocket and i noticed that it was very hot, and when i tried to turn it on..it doesn't turned..only with battery pull. When I restarted the system the temp was 43ºC and started to cool down.
i wasn´t running any app unusual.

It happened to me 2 or 3 times when I had a game running in the background. But nothing I worry about ^^ Some apps are just crashing I think !
I am experiencing the same problem. But my battery percentage sometimes even drops from 90% to 9%.

You say you're not "running anything unusual" in the background - so say what you are running anyway.
Could be an app someone else has had trouble with, and thus you'll get more help.
More info you give, more help possible. "Nothing unusual" isn't helpful.

Mine gets burning hot with net usage without wifi. With wifi there is no problem but with edge or g it gets hot often. Also I have been using xscope pro on hero, samsung galaxy s and now on s2. But this is the first time.
Could it be the radio, modem etc
This problem I believe is caused by UV or undervolting the CPU too much.
I had this problem too. The phone would be working fine even after several stress test (5 min)from setCPU at each and every speed. With continual Quadrant test at each speed after setCPU stress test (3 times continuous). Everything was working fine. Or so I thought....
At times, all of a sudden (randomly) it will freeze and hang without telling you while also heating up in the process because it is stuck at some kind of loop. This is what eats the juice because I believe once it is stuck, it's stuck at the highest speed trying to finish the job (whatever it was).
Sometimes my phone would not wake up for my morning alarm. I would check the phone and to my surprise it would not wake up and had to be turned off and restarted. After checking BetterBatteryStats and CPUspy info, I realized my phone does go to sleep but then it would hang and both software does not tell me what caused it. I just assumed it went to sleep and never woke up or didn't have the juice to wake up. Why not, it happens to people too right ?
After which I decided to fiddling with setCPU. I used the following values and so far so good. Its been 8 weeks now with no craziness.
1600 - 1300mv (I know this is too low to work, i set at this for safety reasons coz I don't use it. But if you're feeling brave 1475 was the setting I believe it worked for me)
1400 - 1275mv
1200 - 1175mv
1000 - 1075mv
800 - 975mv
500 - 875mv
200 - 825mv (I know some use 800mv but encountered one reboot while it was set to 800mv so I stepped it up. So far 8 weeks none at 825mv)
Everything else I did was turn off stuff and checked BetterBatteryStat for which app are doing wakelocks (waking up the phone while it's sleeping) and got rid of those apps and changed them to something else.
After I got my settings set correctly, I'm not experiencing the crazy battery problems and reboot others are getting anymore. I have changed into 3 different ROMs now and 3 different kernels now . All are working fine just had to recalibrate the battery after each ROM flashing.
PS: Please check using CPUspy if your phone is actually going to deep-sleep. If not, try re-flashing and have everything set at stock and try it for 2 days to see if the phone goes into deep-sleep and can wake up properly to do the things it needs. If it can't to go to sleep or wake up, its gotta be hardware related (warranty?).
My rule is, if it works with stock settings and it doesn't on your settings...its not the ROM its you.
Hope this helps people having battery drains and random reboots.
Was on VillainROM 2.4.2 with Ninphetamine 2.04 kernel
Was on Cognition 1.3, 1.4 and its kernel then changed to Ninphetamine 2.05 kernel
Currently on Cognition 1.4.2 with Ninphetamine 2.1.1 Kernel.

safe hot.
It's amazing that peak consumption.
You have not changed the batterystats?
The same thing happened to me on the same kernal.ninpho kernels are set for over clocking and over volting so they can heat up your phone.When i flashed the 2.0.5 kernel my phone went up to 50° and did a factory re-set by itself.If you arnt into over clocking then ninpho might not be a good idea.Ive changed to other kernels after they gave me battery drain and heat problems.
is the battery calibrated?
I had that exact same issue - turned out to be an issue with maps which was linked to CF3d. For whatever reason cf3d crashed maps, which was on a schedule to restart, if I tried to then use navigation the phone would get really hot, then crash. Upon restart the battery was down 50%.
Fixed by doing a full wipe, rom reinstall, and staying away from the EGL beta drivers for cf3d.

Let's take a stroll. Through the useful information garden. And over the obvious bridge. Look! Its a butterfly! Let's name it What kernel u running? So beautiful. It'd also be helpful to know if yer overclocking, messing with voltage settings, if u were charging the phone, and....anything else that could help someone actually solve the problem.
Sent from my SGH-I777 using xda premium
Dip the phone into the bucket full of cold water and see if it actually drops a few degrees.
Rule one of messing with electronics is to keep track of what you did so if something like an overheat or reboot issue suddenly arises, you know what the probable culprits are. without knowing what you were running before the heat issue and now, the only real advise is to compare your setups and see what is different.
I'm not overclocking. I haven't touched the voltages and I'm running the latest shostock with the kernel it comes with. I'm posting this because all I'm doing is browsing the web or just sending a text and my phone is literally way too hot to even hold

Your phone will likely be fine. Most of the components that get hot in electronic devices (cpu, gpu, ect) can handle well over 200 degrees Fahrenheit. Obviously it is still a very bad idea to let any electronics get overly hot -and hard to hang onto because of heat is overly hot.
The first thing to be affected by heat will be the battery life. Batteries "can" (not guaranteed) be irreparably damaged by +160 fahrenheit.
Could lowering voltages cause a phone to run even hotter? I would think it's the other way around...
My phone gets very hot from time to time. Only when it's on the charger though.

I noticed the same problem when on the lastest version shostock a week ago. It would only happen when the phone would lock-up. I can't remember exactly what programs I had running. I believe I was just sending or reading a text at the time. And I don't use the FB app that much. Maybe once a week. Happened 3 times during one day and it would good from nothing to hot in a matter of seconds. Almost too hot to touch. Took the battery out one time and place it under a fan to cool it down. Kind of scared me so I was checking the phone all day long to make sure it was not doing it again.
I honestly just thought it was a bad rom install so I downgraded back to GB after those events. Hasn't happened since. I had no OC or UV going on just stock settings.
I hope there is software and hardware fail-safes in place if the temp gets too high.
I noticed the XDA app after I closed it was still pulling 10-15 cpu power after I killed it my temp went down quick. See if that might be doing it....
Heat
Ok.... The more you have going on...the hotter the phone will be. The cpu's under loads will definatly create temps. So kill apps. Check how your cpu package handle and read up on cup settings. In on smartaz 2 with ioa .

SetCPU is a great idea to get. You can setup a profile so that when it gets over a certain temp a notification goes off and can lower the processor speed. Mine is set to go down too 500mhz if it gets to warm.

I wanted to give a warning to anyone who may be experiencing overheating on their phones. Its most likely due to this.

If u simply change wallpapers and reboot, should be good to go.

i run into this same issue. running the fluxi kernel with rootbox aokp. usually i just pull the battery, wait bout a minute or 2 for it to cool back down and restart the phone and the issue goes away. i usually run app killer after i exit the app.
I've got the Exynos model of the s9+ and it appears to get pretty hot. Almost uncomfortable at times.. this a long with battery drain when I've got barely any apps installed is pretty poor. Note 8 never had these issues.. anyone else experiencing this?
Pretty common for a samsung phone why are you surprised

This is NOT normal. Install aida64 or any monitorung software and check your temps. You may have a faulty unit! My temps right now on exynox are 34.5 cpu and 34.6 battery with normal usage
Is this normal?

Samsung haters out in force, eh? None of my Samsung phones has ever shown any overheating issues. Only phone I've owned that had overheating issues was LG.

Samsung's cooling and clock speed are just fine for normal use. Runnning Antutu is NOT normal phone use. Why slow down the phone for everyone else just to run some silly benchmark.

I'd like my phone to be stable at all times, in any situation, especially at this price point.
I also was shocked to see it since I never had it with any other device in the past.

My US unlocked s9+ never got uncomfortable hot/warm even under heavy task like gaming. And, during normal use like- calling, texting, chating, browsing it never got any hot/warm. Just normal. During 16 to 24 hrs of usage- i got avg 5:30 to 7:30hrs of screen on time
This thread has been cleaned now lets get it on topic...
Same happened to me
Found out that the problem is with battery temprature..did a settings reset and now back to normal..seems to me it's like a bug with some settings
Update
Again battery temps hitting 37degrees during normal work such as whatsapp and youtupe...feels a little warm..asked samsung and told me to get a replacement..
Hi, same here. I have Exynos 9 plus model and all of a sudden, apparently without any reason, it starts to burn...yesterday it was at 42...I'm a Samsung lover I had S5, S7 edge, S8, Gears s3 but now i'm quite upset because I spent a lot of money for it and now I have to do a reset factory to see if I can solve the problem...I spoke with Samsung care and they told me it can depend on the many apps I've installed in it...maybe, he said, it depends on Nova Launcher! I can't belive that I've always had Nova Launcher and now in a 1000 Euro phone I cannot use it because of the heat! The heat it always starts on the camera zone on the back
Had this with the Snapdragons before but the Exynos usually cooler, have you checked to see if it has an app running in the background causing it

Yes, I've installed System panel and Gsam battery monitor but i can't see any app the in particular is going crazy. I can see that sometimes, without any specific use, is starts to burn untill 42 like yesterday; I restarted the phone but i keeped doing it. I've took off all the background working for many apps like spotify and others....Now i'm doing hard reset and I will see...

Maybe better, maybe...you know the heat was going along with a strong battery drain. So I will wait one day to decide if bring it to assistance or not...
By the way, it's not fair to spend time to try to fix problems in a 1000 euros and 3 weeks phone and eventually bring it to assistance and stay without it for one week...I need the telephone for work!

?? mine appears to be normal now...dunno what changed
For me the video enhancement feature in settings was causing increased temperature and also battery loss. Turn it off and it will surely increase the battery life.
Mine gets warm too, but randomly. It stays cool most of the time. But all of a sudden it would get warm in my pocket. Don't know what's going on.
S9 overheating
Hi. I have been having the same issue. I took my phone back and got a replacement due to it overheating but the new phone overheats as well. It overheats the most when I use the Screen Mirroring (Smart View) feature to watch movies on my Samsung smart TV. I am curious to find out if this happens to other S9 owners as well. While I am watching movies using this feature it gets so hot the phone will freeze up halfway through the movie . My kids were watching a movie and they said the screen displayed a message stating it overheated and then shut off. This doesn't happen with any other of my other Samsung phones. I was walking with the phone on my hip on day and it started to get hot as well. I am so disappointed. I really am a fan of these phones but this is a huge problem of course. Also my first phone was was trouble shooted, updated and reset but it still had the same issues unfortunately. I had to go through all those steps before getting a new replacement device.
