battery temperature?

i notice that when i use my phone on 4g when charging the temp exceeds 40C. is this normal? i kno this is dual core but what is the max safe temp for this phone?

I made a post about this a couple days ago and no one answered but mines usually at 94 F and 110 while charging . . i was wondering the same thing..

In my experience
I think this is just a normal occurrence in the android world. Because in both my N1 and G1 i had this same problem they would just become super hot when using extensively(Which kills the battery faster fyi) or when charging, but for charging I have heard of people using Set CPU to lower settings so that it doesn't get as hot. As far as i have ever heard though it isn't great for the phone/battery, but have never heard of actual damage coming from it.

Yes, it happens to my G1 and also my G2x. Usually when I'm charging the phone and using it at the same time, the temp would go up to 43.5C.
Extensive overheating of any semiconductor is bad and will shorten the lifespan i believe, but i think these temps should be 'normal' for these processors. Maybe there's code to tell the phone to automatically shut down after the cpu surpasses a certain temp? Like how modern desktops would.

Well hopefully when custom roms and kernels come out this will improve. My mytouch 4g used to get to 40C sometimes, but after loading up cm7, it never exceeds 35C even when OC'd to 1.2ghz

[Q] how hot is too hot ?

so I'm still liking the sensation have a few problems with it but 1 thing I'm unsure of is how hot can this thing get before I need to worry.
the widget that I use shows me the temperature of my phone
most of the time it's just under 100 or just over 100 degrees fahrenheit, however when I'm playing a game right asphalt 6 this sucker really starts to heat up .
to like 116 118 fahrenheit .
so I ask how hot is too hot at what temperature should I start to worry about overheating or damaging the phone somehow

Don't worry, when I'm playing angrybirds my phone gets at least as hot as yours. Try installing a home-cooked ROM from the development section, these guys know their things and will get you better sensation for sure.
Again, heat is normal. At least with my knowledge.

I know a lot of people don't let their phones get over 45*C, which is about how hot your phone is getting. I would say 1) that temp shouldn't be bad as long as it's not at that for long periods of time, and 2) as long as it isn't getting hotter than that, you should also be fine. Still, underclocking it with custom kernel wouldn't hurt. Our phones are powerful enough that underclocking it a bit shouldn't take a hit on performance, plus it should take away some of the heat.

My phone idles at 29*C and gets up to 45-50*C while playing games (Asphalt 6 is one of them). I left the phone charging in the window under direct sunlight and it hit 48-49*C while idle/screen off (didn't do that again!).
As with PCs, as long as it doesn't stay high for extended periods of time I'm sure you're fine. You can try custom ROMs/Kernels to see if one is better than the other.
OT but I remember my laptop getting to 90*C running an "unsupported" OS on it.

122*F is the damage point.

My Sensation XE gets a tiny bit hot?!?

Ok, ill just tell you where I'm up to here... I bought the XE, about a week ago after upgrading from my DHD. And ever since I started the phone up, I realised compared to DHD it is mega hot.. now before you point out, I do know XE has dual core .. I play games, browse websites, facebook etc.. and I find the phone getting extremely hot to the point I've been monitoring it all the time..
Browsing websites, I've seen temps of around 57 Celsius
Playing games, I've seen temps at 69 Celsius
Normal idle is usually hovers between 30-45 Celsius
I don't know if these are normal for a phone, but in a cold room my mobile acts as a radiator.. sometimes its that hot I feel I shouldn't be touching it..
I had my first one last week and I got the exact same result.. rooted and stock.. Sebastian kernal and stock.. ICS/GB.. and everytime the result is the same.. so I took the phone back to carphone and they replaced it with a new one..
This is what is confusing me about whether this is normal, because the outcome is exactly the same... I've underclocked, it did nothing.. it is also nothing to do with my battery as it usually sits at a comfortable 25-37 Celcius and only rises due to my CPU heating my entire phone and also my entire home..
Could someone please help me with a little info on whether this is normal.. or whether I'm entitled to a complete different handset as carphone as the overall experience with this overheating is making me a little edgy as to keeping the phone incase it explodes..
Right now my CPU temp is 59 Celcius, and that's just typing this message "/..
It happens on both XE's and I'm using system tuner to record CPU temp
Thanks guys

69 celcius? Mother of Heat (yea... A meme)
My Sensation also gets hot, but not that much. Maybe 43 Celsius the max temp It has reached. The problem its because of HTC's cheap battery mainly. Though you shouldn't expect your phone to be cool when it's having a load of charge (process) to deal with

you can definitely expect your sensation to get hot every now an then. especially while charging and doing anything mildly intensive. usually while playing games like dungeon defenders my phone gets super hot even through the TPU case. it's nothing out of the ordinary though so don't worry. it won't explode in your pants

This is the HOTTEST phone in the market

How can I check the temperature of my Sensation?

To check your CPU temp just use system tuner from the market.. and for your battery temp, just search for a battery monitoring app I forgot which one I used as when I found it wasn't my battery I uninstalled

My sensation also gets hot all the time on heavy use.

Open phone dialer and type *#*#4636#*#*
You can remember the "4636" part by seeing that it stands for "info"
This will only show the battery temp tho, but you don't need any 3rd party software

i been gettin same readings on my sensation xe im scared to play games for to long in case it causes a problem with the cpu / gpu... usualy playing games like real racer 2 i get temps up to 70c, i use system tuner to monitor temps..

Look like I had worse temp compare to everyone here.and I wasn't even playing a game.because sensation was too hot to touch.
Here are some pictures and what you said about underclocked is true. It doesn't make any difference and the phone still get very hot.

A new battery may bring your temps down...

i have the same problem, but not that bad. it maybe goes up to 50-60 degrees.
i tested many different roms and kernels.
i have to confirm: underclocking does nothing it still gets hot. i cant say if its the battery from htc, but i can test that soon. i order an anker from amzon. have heard that one is better in other posts here.
i also noticed one thing today. it gets terrible hot while charging and doing stuff. so i tried to charg it from my pc and it does not get that hot anymore. maybe its the charger itself, but i can not confirm that, because it gets hot when not charging to.
what i also saw is that its not that bad anymore after i got a new rom an new kernel. im on vipers and bricked kernel with default settings. no setcpu or system tuner installed.
maybe that hepls

Holy crap, you could almost bake a pancake on that!

During use, phone heats up to 41c/104f regularly.. this cant be normal?

Just web browsing over 3g for 20-30 min will heat the phone up pretty warm to the.touch. it also drains about 1% per 1 min of 3g browsing not even streaming. I'm still on 1.73 att. No apps in background and there is no idle battery drain. Is this normal? I'm guessing not brightness is set way under half

This happened to me only when I'm on like YouTube for a while but mine reaches like 110° F :-(

mine gets hot as well just by browsing. it is right on the bottom left of where the camera is

If I just check FB or draw something, this phone will start searing my thigh when I put it back in my pocket. This phone is definitely HOT(not in a good way...)

I have had 0 heat issues (can only feel it heat up while charging)
Maybe this is because I had the iPad 3, so nothing seems hot in comparison

mine only heats up when im charging and using it at the same time (playing games usually)

Maybe someone should make a poll because I'm having zero heat issues. Played few games the other day while waiting for my gf's OBGYN doctor to come in and check out our soon to be baby and we was playing for a good half hour. Barely any heat at all. Charging produces hardly any heat if any heat at all (noticeably anyways).

The highest I've seen so far was 41C while using wifi tether. Since I came from Nitro HD, which goes to 63C when voice talk on skype or gtalk, and makes your brain boil, this didn't bother me a bit...

Mine only gets hot when I use google navigation, which is understandable. It gets warm when I play hanging with friends, but in my experience that game spikes the processor the entire time it's open.

No heat issues at all for me, I tried to put as much load on the phone as I could to test this issue and all is well, it got warm to the touch but no more than any other smartphone I've used in the last ~6 years...

41c is not hot. My Atrix used to rocket up to 60-70. That was too hot. Think about it: 104 is barely warm enough for a hot tub. You can run a fever of 104 and be ok. Yeah, it's high for a person, but come on - dual 1.5ghz with a HD screen? They can't make that stuff make cold instead of heat!! Just saying...
It stays well under 50c. In my mind... *perfect*

+1. Put your phone on your leg and drive with nav on. Heats up like a griddle after a few.

Indeed it does! Thanks for the laugh also. I can't see that too many things would warm up the phone more than that. You are using the internet, GPS, and putting a heavy load on the battery at the same time after all.

I am coming from an LG Thrive and using GPS never got as hot as this phone or got hot as fast either. The only time it did get hot was if the sun shined right on it. I put my screen to never shut off and run google maps so that it would update to latitude. The HOX definitely gets very hot on a cloudy day when my Thrive would be just warm if that

Just so we're clear, good build quality will often make the exterior of a device hotter. This helps keep the all-important interior cooler. Having my phone feel hot while being measurably at reasonable temperatures is good! You must be careful not to base your opinion of the device's thermal management on subjective senses rather than measured fact.

Oh I don't doubt that the phone has better thermal management. I was nearly stating the fact that it gets very hot when placed on your lap and doing nav... Can't really argue that one.

And I won't argue the subjective notion of heat on your lap during nav! I know 105-110 feels pretty doggone warm (I had to check the temp to make sure it wasn't overheating), but if the exterior is only a couple degrees different than the interior...? That's good stuff right there.

My phone does seem warm to me now that i think about it but it seems to happen when it wants..
yesterday i noticed it would get pretty warm (not ridiculously hot though) when i would be on it for a few minutes (texting, tweeting, the usual).
but then today it was just fine. it was warm but not like it was yesterday.
not sure if i'm just not used to having a phone with this type of casing, (i had an Inspire previously and it didn't seem to get too hot.) i would figure a phone with a plastic or similar material casing would feel warmer compared to something like with a metal back (correct me if i'm wrong )

I don't think that this phone should get hot. It uses a 28nm process while being just a dual core processor. I think that the voltage might be higher than it should be. We need custom kernels and roms for this baby!!!

Could be the system memory. Could also be WiFi/radio.

Running hot

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.
