Battery Temperature

I was reading up on the article about Lithium batteries on BatteryUniversity and it said that 30 celsius is the ideal temperature for the phone, especially when it is charging.
My phone is normally at 23 C during standby, and quickly goes to around 30 in light usage. If I start playing games then it hits 37 C. Rare times it goes up to 40.
I am wondering if my temperature readings are normal, compared to other XT users.
Any tips on how to lower the temperature is appreciated as well. My biggest problem is when I start getting texts just early in the day and my phone starts over heating from them. Sometimes when I get texts while it is charging it goes up to 36-37. I don't know if it has to do with my app (handcent) but I never expected MMS to be such a "battery heater".
I run music apps all the time and it always stays at 30-32, but then once I start texting, bam. 37.

I've had mine hit as high as I believe 48C, but that was really pushing it and with a 100MHz overclock.
Typically any app that requires processing power will make it heat up a lot.
It may be a good idea to use a CPU manager.

You don't really need to sweat it (pun intended). No matter what you do, the CPU will have to work, thus creating heat. The only time you really have to worry about it is when it gets around 50°c. At that point you have to really worry about frying your processor. I have gotten mine up to 54°c and nothing happened. Freaked out, yes and put the phone down to rest for about an hour. Biggest thing that causes temp to go up, believie it or not, is the display. I can listen to an entire baseball game with the screen off and temp will hover around 113°f. Screen on and it goes way up really fast. SetCPU had a profile that will throttle back CPU when temp gets too high. Cool widget is Batstat. It'll show charge, voltz and temp in f/c°.

my phone's usual starting temperature (while phone is doing nothing) is around 30-32 degrees. I believe that it's due to warm climate where I live( room temperature during day is like 30 degrees) after playing a graphics intensive game for 5-10 min, phone temp will reach 40 degrees. Is that normal?

yeah, thats wat i'm wondering too. But then the post above u said as long as its not over 50 then its fine. I've read for other phones it goes up to 60/70 sometimes, so i guess i'm just over wondering.

my average temperature when i just pick up my phone is around 32degrees unless im in an air conditioned room... it usually heats up to 35-37 while im using it to do light stuff like facebook and twitter. my phone gets very hot only when i use my 3g network or when i am downloading a lot of apps from the market. i dont play games.

I am under 40°C with OC to 820mhz. I can have 40°C when I use gps on car when there is a lot of sun.
PS : I you want to stay at 40°C, you can use setcpu and underclock phone when battery temperature is higher.

On standby, my phone is at about 30 degrees. After light usage, it goes up to 37 degrees, which I guess is normal...
I once had my phone go up to 52 degrees. OC'ed to 1.2GHz and was running a game.

SU-870: Over heating and short battery timing

Hi guys,
I bought my su 870 ( Korean version of p720 3d max) 2 weeks ago. I liked almost everything about it except the issues i will state below:
1. Heats up while charging and sometimes stops charging because of heting up to 55 degrees.
2. Heats up while its on standby and 2g network is on.
3. Heats up while on standby and only whatsapp and yahoo messenger r running in background.
4. Heats up like +&^% while i play a simple game or use the net or use wifi or use play store or pretty much anything.
5. Heats up to n over 55 degrees quickly while watching 3d. And no chance of watching 3d and charging simultaneously. Over heats.
6. Gives only 20 to 25 minutes video playback time on 3d at max. Of course heats up.
7. Gives a 1 hour apps usage time including net. Heats up.
8. After restarting works fine unless i put in even one app from play-store and then it heats up.
9. Heats up while using a simple app like whatsapp or if i simply keep the screen on.
10. Heats up if i charge via the USB and shows slow charging on USB.
11. Heats up if i put it in a pouch.
I've tried task killers, they help but not much, have to delete apps to make it work.
That is all i remember for now but u get my point, IT HEATS UP. I'm running stock unrooted ginger bread 2.3.6. I want to try upgrading but currently have no internet connection. So i would really appreciate it if anyone could help me out. I use my S.G.S.2 in an Xmart all plastic pouch, played full hd videos on the S2 while modern combat was running in the background n it still didn't heat up. So please help me out. I really like this cellphone n i don't want to replace it. Thanks.

probably by any reason you have constant CPU usage. Download CPUSpy and check that.
Download Wakelock and see which program make a huge wakelocks there - uninstall it.
Then if your phone is rooted download SetCPU and set the Governor not to be on Performance, but s.t. else like OnDemand

thanks for replying. i did what u asked. ive only got whatsapp in wakelock with 1 minute average. nothing else.
as ive already mentioned i dont have root.
in cpu spy at
1200 is 3.2%
1008 is 9.8%
300 is 32.6 n 50.4 in deepsleep.
so no problem in there either.
since yesterday ive recharged it twice n during recharge it hovers around 48 degreessometimes 45 or 44. during average use it stays at 38 t0 41 degrees, and in light games goes upto 48, in heavy games it goes well over 55.
its not he3ating up while its either anymore but it hetas up everytime i use the cam or watch video or games. is that much heat normal for this? also it stops charging at around 53 degrees heat
i would like to add the the region on the right side of the battery is where it hetas up so much. in battery its acceptable. And it heats up so much wjile charging and watching a video that it stops charging within ten minutes because of exceeding the 55 degree mark.

I have original battery. Just now when i was charging it chrged to about 60 % and ten stopped charging because it heated up to 55 degrees. just because playstore and whatsapp were open in background and downloading skype from play store via my 2g network. now its slowly cooling down. Anyway thanks for trying vlad.
CAN ANYONE HELP PLEASE.

So ive been testing it a lil more. i played a hd 3d movie on it, it was qround 42 degrees when i started movie n it was charging. after 40 minute of playback it is at 53 degrees. no other app running in background. I even monitered the cpu frequency and 1 core was on 50 percent and the other was completely off at an average.
Edit: while testing i kept the back ventilated at 26 degrees temp.
Guys help me out please. is it supposed to go so hot? and does ur cellphone stop charging after reaching 55 degrees? i would realy appreciate any feedback. i dont think any cellphone should heat up above 50 degrees no matter what the condition or loads. my s2 doesnt even when ive got it fully covered wth plastic bag.

my p920 is charging right now (1amp wall charger) , room temp at 31ºc phone temp at 35ºc... even in performance governor @ 1250mhz overclock i think i never saw my phone reach 50ºc and it never overheated.
unfortunately what you describe sounds more like hardware problem than anything else. i would try factory reset just to be sure it isn't some software hogging the cpu and then send to lg if problem persists.

CPU temp 70 degrees celsius

Hi
The temp of the CPU in my note 10.1 reaches 70 degrees Celsius during gaming...
Is that a normaal temp ? It is measured by System Tuner (by 3C)
During normal use it reaches 45 to 50 degrees.
It is not overclocked, but undervolted bij 50.

It seems a little high. Should be idleing around 35c or so and high around 50-60c. Dont quote me though lol

It seems high, I will try to heat mine up today to see where I can max out out. At 70 C, that's like 160 F, that's hot enough to cook an egg my friend. Even at 60 C, I would worry. Does it get noticeably hot? Mine can get warm, but not hot, and I feel it in the upper left corner when looking at the screen.

Well...it is hot out here (weather). The back top left corner feels warm...not hot....like a little warmer than my skin...i think around 40 celsius.
I flashed rom again with no tweaks what so ever. When stressing the cpu now it gets 60 celsius
I did the same test with my cellphone...note 2....and it gets the same temp. Can it be that these note devices just get hot? I haven't got probs with both. Just wondering about the temps

Interesting, well I guess if you have no problems, maybe it's still in a safe temperature range, mine never got over 40 C., for what it's worth. Also, I maxed out my RAM. I have never seen it, but I thought there was a warning if things got too hot.

I just had as many things open at once as I could, attempting to use as much of the 1.78 gb of ram that is available. Trying to get it as warm as I could, to compare it to the 70 C that the OP was experiencing. I just worded it poorly, I just reread it, terrible use of the English languages.

I'm not much of a gamer, Asphalt is the game I used to get it warm, it's the warmest running app I have. Still doesn't get that hot, I would try with it plugged in, however the touch screen gets a tad wonky when I use it plugged in. Does 70 C, 158 F seem too hot to you?

[Q] Serious Nexus 5 overheating problem

Hello. I'm new with the account here, but been reading this forum for years.
I'm creating this thread because my new Nexus 5 (which I have for 20 days now) is overheating more than a normal mobile device should.
When i bought it, it had 4.4.4 Kit kat android, and I had that one for about 5 days, and in that time, I didn't notice any overheating, or maybe didn't pay attention, can't remember really.
But after installing official Lollipop 5.0.1, the device is heating pretty good even when browsing internet for 5 minutes, at about 30-40% brightness.
**** Please tell me if some of your devices are acting the same, and is it worth a try to install back an older android to try if it will stop overheating, or my device may be faulty and should I take it back for another one (or maybe switch to LG G2) ?
Because I'm still unable to post image links, i will write it down:
- Ambient temperature: 23 degrees Celsius
- The temperature sensor is taped on the back side, at the side of camera, this is where it overheats most. (even if not using camera)
- Phone temp after staying on standby with screen off: 28 C (it's not warm but it is warmer than desk which it is sitting on)
- After staying idle on home screen with screen on for 10 minutes (50% brightness): 30.5 C
- After chatting on Messenger for 10 minutes: 34.3 C (feels warm)
- After recording video for 4 minutes: 41 Celsius!!! (almost uncomfortably hot in the whole upper half of the phone, both the back side and the screen)
- After 15 minutes letting it cool down, with screen off of course, it is 38 C (still hot to touch), and it stays like that untill I reboot the phone, then it cools down.
The test took about 50 minutes, and after that, battery was drained for about 25%.
-While charging, the phone does not overheat, just gets a little warm which is OK. (haven't tried wireless charging)
P.S. I don't play games on the phone...
Please act quick in case I should return the phone...

the only time my phone gets hot is when im intensively doing a lot of things..
for example.. im playing ingress, have tether ON, and my two sons are using their tablets connected to my phone playing ingress too..
but if i turn off the game and turn off tether, it cools down..
to me it sounds u have something intesively using your CPU and perhaps GPS and other radios.
hold power button.. when PWR OFF shows, long press it and reboot into SAFE MODE...
use the phone for a bit and see if it gets warm... this should tell you if its apps installed.

I only used wifi, no tethering, no GPS, 3G, NFC or any other radios, cell signal is good so phone is not searching for it.
- In safe mode, it still gets warm when using camera. When browsing internet and watching images in google search, also but just mild warm..
- But after sitting and thinking, I've found a problem! After recording with camera and leaving it to cool down, it didn't cool down because it had to make an effort to upload that 5 min video on Google drive via Auto backup!
After turning the Auto-backup off, it is now much cooler!
I will post tomorrow with the results, if something changes...
Anyway, thank you!

First of all, "warm" doesn't mean anything.
Battery temperature does not mean much either, as the CPU is what generates the most heat.
There is a battery temperature throttle that reduces the CPU frequency, but it is almost entirely pointless as the CPU will always reach it's own throttle temperatures MUCH, MUCH earlier than the battery will. The CPU starts throttling at 65C CPU temp (NOT battery temp), and shuts itself down at about 105C CPU temp. Unless your battery somehow reaches a batterytemp of 70C+ (nearly impossible because the CPU will always hit it's throttle first), then I would never even take it into any sort of consideration unless you have a physical battery defect.
Using the camera generates heat since it's CPU and power intensive.
Using the phone in general will generate heat.
Keep in mind that mobile devices are passively cooled, not actively cooled with a fan/liquid.
Not sure what you're so worried about.

Lower your brightness

Lethargy, thank you for a short physics lesson. I'm already into physics and cooling systems so all is clear. I was just worried a bit because all of my previous phones weren't getting this warm (hot), but also never had a multi-core processor in phone eather, maybe that's the reason why I never experienced this before.
Battery temp (measured with app) gets up to 40-42 degrees Celsius, while the phone case gets up to 41 when recording video. Of course that temp won't damage the device, I'm not worried about the processor, but that temp is degrading battery life, in long term.
And about the brightness, phone is not meant to be used at lowest brightness all the time, so that shouldn't be an excuse for high temps. Just sayin'...

The only thing that sounded odd was how it wasn't cooling down until you rebooted, but it sounds like you figured that out with the automatic upload setting.
41-42c battery temp can be normal after prolonged usage, though personally I usually see that after a short gaming session. My brightness is around 40% and high brightness will cause extra heat.
Otherwise the phone is very thin so you can feel the stacked SoC and RAM heat up through the skin fairly easily, right around the camera area as you mentioned.
I think each device and CPU is slightly different and can vary by a few degrees under load as well.

Your temperatures are fine and you shouldn't worry about it. It's average for a Nexus 5, and there are throttles/shutdown temps anyways, for both the battery and CPU. I've had mine for a year and there hasn't been any sort of issue, normal usage should be negligible to the condition of the battery.

Ok, everything seems to be ok then. Now I can go to sleep without worrying Thanks guys!

Galaxy s6 throttling as hell

Since I bought my gs6 I have noticed the soc temp heat up very quickly and couse a massive throttling of the gpu above all ...so that performances go down of 50% expecially when running antutu ...is that normal or should i send back my phone to warranty

every CPU throttles, the S810 throttles even more, they have to, and don't run benchmarks, they won't do you any good, if in day to day usage the phone heats up it's normal, my S6 do heat up but i never noticed throttling, i never noticed lag when it becomes hot.....try to use your phone normally without ****ty benchmarks...

Thanks for your answer
Yes I know benchmarks are quite worthless ..but it's not just about that..i notice this even while gaming ,browsing and even doing light stuff ..its however pretty much annoying

i don't play games that much, i only play couple of games like boom beach, i don't know if this game considered heavy or light, but if i play it for about half an hour the phone heats up a bit but it doesn't lag at all....in light usage usually it doesn't heat up, but even if it heats up i never notice lag, the phone stutters in some places but no lag.....

Hi,
Please install the app called CPU-Z to check your device temperature. Also keep in mind that depending on where you live, it's easier to heat up than on other regions, as the external temperature does make a difference.
To throttle it needs to get very hot. Check if you have Mobile Data and Location turned on when not needed, and specially Mobile data when you're out of range, they consume lots of power and heats the device up considerably. Also, Wifi if not connected will keep searching for somewhere to connect and consequently will use your device power and heat up.
Another thing to keep an eye on is background apps and the external temperature as mentioned before. On S4 I faced a serious battery drain and overheat problem due to background apps not letting it sleep.
All the best,

Already have cpu z on it
The temps get up to 80 degrees celsius when under really heavy usage ..of course this temp refers to cpu not to battery that stays always around 33 and 37 degrees
P.s i dont notice lag either. .even when performance decrease its good enough..i was only qondering wether it is normal or not

You may have a lemon S6. Return your S6 to Samsung for warranty replacement.

And here's one of my device after running AnTuTu benchmark:

I noticed that during the benchmark it got to the 80 degrees range, but it lasted a few seconds, if your device get to 80 degrees and stay at it, maybe it isn't dissipating hear correctly.

80 sounds crazy not a bit high

80 its high but device can reach that temp sometimes. Example if you play and fast charge same time it can get that temp. And not to forget outside real temp. Here its so hot... up to 40degrees

Hi All,
80 degrees is not as extremely as you might think. People tend to think its too crazy or high because they never would have seen it and the most times they check their cpu temps on CPU-Z it will be hovering around 40-50 degrees. The best way to check your temps in S6 is to open CPU-Z/AIDA64, have it minimised in a smaller window and drag it to the very corner of one side, while this is running, open a game like dead trigger/skyforce and notice the temps. Also, do the same while performing an antutu test. Yes, the scores will be greatly reduced and the temps will be a tiny bit higher because of this smaller window running simultaneously, but you can compare your temps pretty easily. Also, try to be present in a ambient temp of 26 degrees rather than upwards of 30 for a fair comparison with fellow users. According to me, 80 comes up at times but it lasts only for seconds (S6 starts throttling exactly at 80 and beyond that the core clocks gets aggressive reductions) but it will never be constand even while running a game. Mine CPU idles @35 degrees with ambient temp being 26-30.
My temps : (All temps in Celsius)
Ambient temperature 26 - 30 degrees :
Battery temp : 25-30 degrees
Idle : 32-35 degrees
Slight tasks (Whatsapp, checking notifications) : 37-39 degrees
Multiple applications : 38-43 degrees
Game - hungry shark evolution : 47-52 degrees
Game - Dead Trigger : 55-62 degrees.
Ambient temperature 31-36 degrees :
Battery temp : 33-37 degrees
Idle : 41-44 degrees
Slight tasks (Whatsapp, checking notifications) : 46-50 degrees
Multiple applications : 47-55 degrees
Game - hungry shark evolution : 55 degrees
Game - Dead Trigger : 65-70 degrees.
Also i've noticed that the CPU temps increase for a flash second to 65 above while installing multiple apps from playstore. Try updating/installing multiple apps from playstore, have the CPU-Z open, and exactly while the app finishes downloading and starts installing, there will be sudden spikes in temperatire depending on your ambient conditions. But, never reaches high temps constantly.

all right, thank you all guys for your replies. So..i sent my phone back to samsung and got a new one 2 days ago,i can definitely confirm that the phone heats up exactly like the previous one , maybe just slightly less(i mean 3 degrees..nothing craze).
For anyone suffering of this ''issue", notice that temps may drastically change depending on wheater temperature ,humidity, etc. if weather is at 40 degrees ur phone wont surely get to a lower temp.
BTW it s clear that this phone heats up and throttles ,some may notice that others not, so unless you receive overheating warnings or have other serious stuffs on ur device ,do not exchange it for a new one because certainly it ll be quite the same as the previous one. Oh it 's quite clear as well that folks claiming their device doesn't exceed 60 degrees under heavy usage either are liers or super lucky ones with uber super powerful units...think its more probably the first option.
regards ^^
