Hi Guys, I'm having a problem here with my XT720's temperature.
When I have a 3G signal and connect the data, for example using ebuddy and just leave it idle.
The temperature is getting hotter and hotter.
I got 50 celcius this afternoon! Just to leave it idle with ebuddy running and getting a 3G signal.
But it doesn't happen when I tick the 2G Only.
How can I fix this?
I'm using CE firmware with apps2sd&buildprop from navalynt, and JIT from khalpowers.
My operator is using GSM1800 and WCDMA2100, Axis Indonesia.
Thanks for the help
that is sort of normal...
you'll get high Temp whenever you do a lot of CPU processing like 3D games
or when you download a lot of stuff via 3G and/or WiFi
So it's normal then?
It's so hot when I touch it.
50 celcius is really hot I think, being that I didn't download anything. Just ebuddy idle, or when I use datalink connection app, which ping every 3 seconds.
It's just ping, ebuddy is idle.
What's your average temp?
I read in motorola website, the temperature must not exceed 45 celcius
no wonder....
your internet connection is always ON, that's why it's hot
why are you pinging every 3 sec anyways?
I ping to test my data connection, I force it to be always on. On my nokia, this was not an issue, it doesn't get this hot.
On my nokia, I'm always online with my ebuddy 24/7, and it's fine.
Now on XT720, it's getting this hot with 3G on.
Using battery monitor widget I can monitor the temperature, and it's range are 37 celcius just idling to 42 celcius when playing a heavy game.
42 celcius is warm.
But when you call someone and got a 3G signal, or while chatting with 3G on, it's getting hotter past 45 celcius...
It's hot.
With this heat, I'm afraid to break my device.
i also get this temprature when browsing, this thing can fry eggs
My XT720 gets very warm when the 3G radio is used, I consider it pretty much normal.
If a lot of data is transferred, it will get quite hot to the touch. In the upper part of the phone, in the center right below the camera.
Hasn't seemed to cause any issues, and the few XT720s that I've had (warranty replacements, but not related to heat) do this.
EDIT: Also, interestingly enough, it seems the WiFi antenna is somewhere around the "8.0 Xenon" sticker, because I notice a slight signal drop when placing a finger over that spot.
im using setcpu to control the temp....

How do you use it bro?
Is it the feature that you can downclock the proc at certain temperature?
Hey radiontaro,
not sure if you figured this out, but all you need to do is create a profile that throttles the CPU (or sets the CPU frequency to a lower value) when the temperature exceeds a certain threshold.
hope this helps!
No I haven't figure it out.
The hot temperature is because of the 3G connection, not the throttle of CPU, so it still hot when I set it to lower frequency.
If I'm not on 3G network, or use 2G Network only on setting, the temperature's fine.
its actually a glitch. i found out sometime back its due to the 3g network going on full blast after a connection or a call has been made. and its constantly trying to search for something. for me after i cleared the dalvik cache it disappeared. also it could be due to the background market service thats making the antenna work overtime
Mine typically runs idle at about 31 C and will go up to ~40 C during heavy data or CPU usage

My current setting is Stock 2.3.4 ROM + Netarchy 1.3.0.12 kernel.
I noticed that it has been heating quite often.. and I can smell as if it's burning if I put my nose directly to the phone.
SetCPU shows that my phone is around 39~42 degrees when I can feel the heat on my hand.
My current SetCPU setting is max 1000 min 100 ondemand. I didn't change any voltage.
Is my device okay? I have Best Buy BlackTie In Plan.. so I don't know if I should exchange it.
check your background apps. maybe try restoring to stock then use the phone as you normally would. observe your phone temp. if that doesnt do you any good then i think you might need a replacement.
Mine gets that high, only while on charge and streaming music or running gps etc with the screen kept on. Or just constantly playing with the phone like a crackhead while on charge.
Idle temps while charging are around 37c (screen on)..
I left my phone with screen off for 30 minutes and now it's back to 29 degrees per setCPU.
I began to wonder if this is the smell from the phone itself or the actual burning because this smell continues to exist whether the temp is low or high.
I just do normal browsing, XDA app, and Facebook.. then it goes up to late 30s and low 40s.
It's probably just the new phone smell (ie fresh electronics)..
It seems like heating is somewhat of an issue for the new Galaxy S II as well.
I have been using wireless tether and have noticed my phone is getting really hot, I check and it was at 51 degrees celsius, so I shut off Wireless tether and it cooled. But is 50 degrees dangerous to have it at? Sorry if this is a noob question

Hmmm, that's strange. I use wireless tether almost all day every day, usually with my phone plugged into a charger so the battery doesn't die, and I don't think I've ever seen the temp go above 40C.
I could be wrong, but I believe 50C was the cutoff point for when starting to damage your processor. Are you overclocking at all? If you are, it would be a good idea to set up a profile to throttle down the overclocking when the temperature gets too high (and when charging).
Stock Kernel?? I use mine all the time for hours, I have never seen a temp issue. The Hotspot is a thirsty ***** though, I can watch the battery drop.

Stock battery?
Thanks, Robertus
50 degrees...celcius?
I have Battery Widget app and the temperature always hover between 86 to 105 FAHRENHEIT, and this is NOT using Wireless Tether. Is my phone defective?
Turn your screen off and keep your phone on a hard surface, not a carpet or bed, and it should stay noticeably cooler.

Not at all. 50 degrees Celsius is 122 degrees Fahrenheit. If you're phone starts getting that hot, then you should be a little concerned. Right now, my phone is at 97 degrees Fahrenheit, which is pretty standard.
As always, if you are overclocking you should really have a safety profile set up to force a lower processor speed when the temperature gets high to prevent damaging your phone.
I've had my phone getting uncomfortably hot while tethering in areas with subpar signal strength. Probably something to keep in mind.
These phones can handle temps of ~130 if I remember correctly. Processors get hot which is why company's make.them able to handle such temps. If your phone gets too hot your notification led will blink and your phone will shut off if it does exceed a set tempature (not sure what that temp is but obviously you didn't hit it). Your battery life may take a major hit with these temps but your processor is fine.

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.
I find that frequently my Q runs hot. There doesn't seem to be a pattern to when it happens, but often it's hot enough that it's a bit uncomfortable in my pocket. Anyone else?

Before I turned off LTE the phone got extremely hot, since then it's only occasionally reached uncomfortable levels (~104F battery temp according to my widget) and each of those times was when I was in a marginal signal area without WiFi data. Bluetooth with WiFi looking for a signal also seems to get it a little hot (maybe 102F), but nothing like the Evo Shift which would hit 108F under the same configuration!
I have mine temps set to C but the other day it got up to like 64 degrees. Not sure what that is in degrees F but I know its dangerously high.
What temp are you monitoring? To me 64C could only be cpu core, which would indeed be high but not dangerous to the chip (my desktop core routinely hits 90C as does my GPU when stressed, I run a minimal fan speed passively cooled rig for noise reasons). Most components can hit 110C internal temp without damage. However batteries don't like getting above 40C much at all, nor does human flesh.

Supposedly that's battery temp. At least according to SetCPU. I figure its off somewhat cuz it reports my processor upwards of 300 C and I know that's not right. But I have a case on my phone and when its reading high battery temps the back of my phone is hot (not just warm)
I Keep wifi off, and when in poor service areas my phone gets hot. If I put it in forceroam, then she is fine.
My wifi is rarely on. Occasionally my temps get a little warm but not too bad. Any time I use wifi tether it climbs though.
Edit: After re-reading arggghhh's kernel thread i realized the kernel i was using has the gpu overclock attempt. Flashed back to version .04 and its still getting a little warm but nothing ridiculous. Haven't used wifi tether yet so i cant report on those temps.
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!
