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.
When playing a certain game, Card ace casino, my phone gets pretty hot, around 60-65 Celsius. My friend says her palm pre (not even an android device) also gets hot playing this game. Is 60-65 too hot (causing damage?) or is it okay? The phone feels pretty hot, but not so hot you can't touch it. The battery isn't as hot, so I don't think it's causing damage to the battery. I did just turn off force gpu rendering to see if it will help, as I heard the GPU causes many of the heat issues. At the moment, while plugged into the wall, it's idling at about 50 C
Is it actually a really graphics intensive game?? Hard to imagine a game like that would be. Maybe it's just horrendously written.
You can try downclocking your cpu/gpu to see if the game is still fluid to play. Or adb into it while playing to see what your loads are (or enable the overlay in the develop section).

That should be normal, thats the problem with phones with metal backs, metal absorbs heat. Underclocking should help a bit but theres nothing wrong with the phone. Happens to me all the time.
No, its not a graphics intensive game at all but I had force gpu rendering ticked in development so i was curious if that was it. Thanks for the reassurance, it just sounded like a high temp to me. When my last sensation overheated to 75 it caused a bright spot in the screen (T-Mobile warrantied it). Don't want that to happen again. It is a very poorly written app, there aren't even hdpi graphics for it but its the only way I can play with my friend. I still reach temps of 60 while playing angry birds though, so it must just be the way the sensation is built.

As time goes on I think all HTC phones overeat and unless they do something about it the overheating will just become more prominent. Turning down your brightness usually helps FYI

Because a lot a people seem to be suffering from over heating. I decided that it might be useful to bring this app to users attention.

Yeah, I got this one also. Don't know if it's really doing anything. Every now and then it goes off when my phone is on the tylt charger.
Don't need root to stick it in the fridge #troll :silly:
I have no idea how the app works, but I have a feeling you'd be trading cooler temps for sluggier performance.
I never get a warm phone. My m8 use to get warm, but not this
Been using coolify since it was released along with the apps shown below, phone is flying and doesn't overheat

Using Greenify since S III its really good app and prevented my phone lagging too much. Coolify seems doing nothing. At least for me still heats and reaches 43C on 10 min. single game. Angry Birds, Simpsons Tapped Out etc.
Ahhh, I don't really run games, gaming appears to heat stress most phones
Wrong temperature shown by coolify
I installed the coolify application and sistematically shows a temperature that is more or less 20 degrees lower than the temperature of the Xposed module that shows the same information on the notification bar (I don't remenber the name),
The Xposed module shows the real temperature. In fact upon reaching 100 degrees the phone turns off automatically for high temperature.
It happens to me often browsing complex internet sites (i imagine containing a lot of javascript stuff and/or images).
The application not helped in any way (I will test a little more before uninstalling)
I have an italian 3 brand 10G.

Different materials and phone construction are making it possible for processors to run at higher temps and not really heat stress components (new LG G3 here and I'll see 100 degrees occasionally, when playing Eufloria or something) but normally I think we can be not so worried about a phone feeling 'warm' in our hand when in fact it's not much warmer than our body temperature.

Uhm, mine LG G3 turns automatically off upon reaching 100 degrees.
If you try to touch the power button it's really hot (maybe is right back processor).
Anyway coolify seems not help
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!

Hey everybody,
Since I work at a phone repair shop I have access to a lot of little parts and things to do modifications to phones.
Lately I've been thinking of taking a heatpipe from something, and slapping it into my Pixel 3 just to see what kind of difference it may or may not make.
I have a heatpipe from a Samsung S10 already pulled just waiting for install.
But I'm hoping some people can chime in with the temperatures that their stock pixel 3 devices generally reach, so that I can compare after the "mod".
Preferably three temperatures:
Idle
Load (Video)
Load (3d game)
And if your feeling generous a fourth temperature from using a CPU burn in app.
I'm currently using CPU monitor to check my temps, so using that would be prefered so that there are no different temps between apps.
And yes I realize this won't be a perfect test due to what apps everybody may have running in the background, but ballpark figures are better than none at all lol
For reference my temps stock:
Idle: 31°-33°
Load (Video): 35°-37°
Load (3D game): 36°-40°
Ok so the heatpipe has been installed since later in the afternoon yesterday.
The heatpipe has cooler Master thermal paste on either side to help heat transfer.
It sits directly under the motherboard, and runs underneath the battery.
Initially the temps were a little worse of course since the thermal paste had to "set"
But I now have some base figures.
At idle: 25°-31° (this large variance is likely due to background apps updating/running such as Facebook, messenger, email and ambient temperature however it mostly sits around 29°)
Load (Video): 29°-34°
Mostly used YouTube, but watched a movie on Netflix
I did have a 3 hour google duo video call with my favorite lady. After about an hour and a half the cpu hit 47° and stayed between 45°-47°
Fairly hot, but prior to this I've seen it hit 49° on a duo call so I'm not complaining.
Load (3D game):35°-37°
Obviously this one is subjective due to the game, and what settings it's on. Though temps didn't seem to change much.
One thing I have noticed from all this is that cpu monitor also tells you your battery temperature, and weirdly enough the battery has actually gone down in temp 2°-3° from where it would normally sit.
What I mean is that at stock the battery was usually 1°-2° celcius higher than the cpu temp. Where as after this mod it usually runs the opposite 1°-2° lower temp than the cpu.
