Hi there,
I've been using DHD for more than 2 months, and I have problem (or feature, depends what month it is
Where I live we have air temperatures around 37°C right now.
When I normally use my DHD, it runs with battery temp at around 31°C, sometimes a bit more. But, If I put it on a windscreen inside my car, it overheats in few minutes reching more than 45°C which is overheting limit. All this means that I can't use my DHD for navigation, or for Blackboxing (DailyRoadrs Voyager, Autoguard).
I drive myy car daily for more than 200 kilometers, and I find my self in very odd situations daily, and if I have to prove my innocence having my drive filmed can help me a lot. Thats the reason I would like to use this blackboxing programs daily.
I was thinking to undervolt my DHD or set lower CPU freq.
Does any body have similar problem or maybe an answer.
Thank you for your reply.
Well if your dhd is in the direct sunlight inside your car it's normal that it's that hot and there is nothing you can do about that.
To lower the battery drain, and as a result the battery temperature, you can lower the screen brightness, or UC/UV your cpu. Those are the main factors of the battery drain.
Furthermore you can turn off the data connection while driving because it needs way more battery when you're driving

I preordered the Galaxy Nexus for Sprint the week before the release, and I've been having heat issues since I got it.
So I paid for "TempMonitor" on Google Play so I could monitor the temperature of the battery but the battery was only 40c and rarely goes above 45c. The CPU however is what is getting hot. When I say this thing gets hot, I mean it, and only while charging and in use. If its not charging, it will get warm but not hot like I'm talking. During light usage the CPU will rise to 55c or more and while playing a game it has gone as high as 65c, it burns to touch the screen at these temperatures and when it gets hot like this the touch screen also becomes unresponsive for multitouch.
Already starred the issue #23044 on android's google code page for the multitouch issues though.
Exchange if possible. Those temps seem to high to offset by anything you can do tweaking wise. Or you have something rogue using cpu cycles keeping the heat up.
...
Do you have a case? My Seidio Active does a GREAT job at insulating the heat coming off the phone and holding it in.
If I'm playing a CPU/GPU intense game or app, it'll easily be 15 degrees warmer with the case than without it.
I do have a case so that's probably the reason. Mostly silicon rubber. I've just never had a phone get so hot I thought it was unusual.
I use Watchdog Lite to monitor background apps for high CPU usage and it rarely ever goes off. The only app I use that it notifies me about is Facebook which has the tendency to use 40-50% CPU while in the background
This phone does get hot when I'm on the internet and only then its the top half where I imagine the CPU is

I took off the case.and have been browsing these forums. Still running as hot as 65c with random jumps in temperature. It will go from 55 to 65 in a matter of seconds.
Over 3G? That would be almost normal. Also stock correct? I get a little bit warm over wifi browsing so I would assume some heat over poor 3G signal.

My average CPU temp is 34°C (93°F), and I go up to 67°C (152°F) when I play games (like GTA-VC).
Do you think it's normal that kind of temperature from the S4Pro ?
Actually this is really low...
67c on high load like games, which stress the cpu?
My device goes to 80c easily, starts to throttle cpu speed and shut down cores, all of the devices do that. This temps are normal.
By the way which app you used to measure that temps?
If you really want to see how your device holding up,
Download that app:
https://play.google.com/store/apps/details?id=com.into.stability
While run the classic Stability Test measure your cpu usage and temps.
Personally I use FauxClock.
After a few minutes you'll see the high temps and the cores throttle.
Oh, joining this question. Just got a 32Gb LTE version and found out it's getting quite warm when playing something like Osmos, Doodle Jump or something. I don't know how to get the exact temperature, cause monitors I' found on market, show only the battery temp. Anyway who else gets his N7 warm/hot when some heavy app is running? Asking, cause my friend also got the same N7 and I don't remember it to be hot even after running 3D games for quite a long time.
I used the app "System Tuner" from gplay.
Apparently, your StabilityTest app requires more power than GTA-VC, I recorded a 82°C with a 50mV undervolt (on Franco r3 kernel) after a 8min StabilityTest, then I just stopped it. I'm a little afraid of this kind of temperature :/ Are you sure it's okay ? I don't know well the mobile device world...
That's the real temperature , even higher,
And you don't need to worry too much.
Your device will turn off if the CPU reaches too high CPU temp,
And 80-90 c is fine. The soc is built to work on that temps.
As you could see your CPU shutdown cores and lower cores speed while the temperatures going higher, that's called throttle.
You don't need to worry too much.

StabilityTest can load all 4 CPU cores 100%. You won't find a game that does that.
The CPU will be thermally throttled (clock frequency will be limited when the temperature is too high), so you won't damage anything.
And is the average temp of 45-50 °C normal? I'm just using Skype and surfing the internet.

If you run a adb logcat while gaming you start to see alerts going off for high temperatures when it gets around 70°c or higher. I found it very interesting that it was alerting when it got that high instead of ignoring it like you say till 80-90°c.

Games use GPU which adds much more heat to the conclusion.
Stability Test don't.

The device doesn't ignore it till 80-90c. It's start at 60c.
I just say that it's safe temp for the soc to operate. Which means your cpu never use all cores, and the cores that active wouldn't be at the highest speed, while the cpu reaches 60c, more heat more throttle.
Ok thanks to all of you, so it's like computers : if it's too hot, it will stop before it reaches a dangerous temperature.

Those are quite ok. If you include skype with voice/video calling ofcourse. I just get about 30-40 with just surfing and chatting facebook messenger skype/yahoo/viber on background
I'm fairly sure the CPU tends to downclock itself not because IT is getting too hot, but because it's generating too much heat for the battery. Almost all CPUs can easily withstand upwards of 80C. Batteries, on the other hand, can't.
My gt-i9192 can get a bit hot. Reaching even 45 Celsius when I am outside using for example the maps app (needs gps, data and wifi (it claims it makes GPS more accurate and it seems to do)). or a game or browsing the web. Specially if the environment temperature is high (I consider 25º or so "high" for environment temperature). I am not sure if 45 is too much or if it is just okay fine. It does get uncomfortable and the temperature guard app defaults at 40º for the "too hot" warning.
How hot is too hot?

Keeping GPS on does get hot, particularly if you are using a navigation app. Depending on the games, some times it can be also demanding. But if you also get 45 degrees on browsing, than something is wrong.
You sure if the app is reporting the correct temperature? 45º should be warm to hold in hand (a feel-able temperature).

Sure, I feel the hotness.
I used to get 45 degrees while browsing if the environment temperature is hot. It hasn't happened in a while, recently I moved to a custom kernel, so maybe that fixed it.
My i9190 has been getting really hot lately, and whenever it does the battery drains crazy fast (about 35%/hr). Strange thing is, the task manager shows no apps consuming CPU nor RAM.
I had a similar problem with my old S2 that started after I had had it for about 9 months. At the start of a day battery consumption wasn't bad, but if I used it for an extended period of time it would heat up, and battery consumption seemed to rise linearly with the amount of heat the phone was emitting. There were incidents where it drained to half from full in a matter of less than an hour.
I welcome. I have i9192 and at me temperature at the game on facebook also achieved 45 "C and I returned it to the shop. At other users of this phone what temperature is while looking the Internet through??Can the shop he will accept the warranty??
Ah, I did forget one thing, since I didn't stay on original ROM for long. For those that are on original Samsung ROM, I guess it normal, since the default CPU governor is set on 'performance' mode. Your CPU is running on the highest speed all the time, and most original ROM does not enter deep sleep.
JoeCastellon: If you are on the original ROM, it would be your problem of battery drain. Using a custom Kernel or ROM like vexorian would solve your problem.
groda: Same, if you are on original ROM, running any app even if it not games, it would raise the temperature at a very rapid rate.
I thank for the reply. When install root and to lower the clocking of the processor? by the way, the new ROM will lower the temperature?
My latest "[doh this got too hot]" experience was on Sunday, I was using c0bain's kernel which AFAIK has the "on demand" governor.
I am now trying SilviuMik's ROM, will test during a week and see if the hotness happens again.

Custom/modified ROM or kernel will lower the temperature. Original Samsung ROM - no.

For me a battery is overheating. I want install root and new kernel. I have a question. Which kernel will lower the temperature for me? As install new kernel could update whether I will be through wi fi??
The kernel itself will not magically lower the temperature. You will need to manually undervolt the cores to achieve that, which requires a custom kernel which supports undervolting.
Changing your kernel will prevent OTA updates, if that's what you're referring to with the update through WiFi
My cores are working now on the maximum. install the root can I lower the clocking of the processor this way?
It which kernel will be good for my i9192? What thread is it possible to find him in?
Yes with kernel and appropriate app you can adjust clock settings.
Not sure if 9192 has a custom kernel that supports this. Check the development subforums
Okay found one.

Is there a way to reduce it? My phone slows to the pace of a sloth far too frequently and it seems correlated with temp.
I'm assuming that's the cause because when I look at the CPUs in CPUz the last two go down to 633MHz when things are getting slow. Also seems worse with a case but could be my confirmation bias. This is particularly apparent with the camera, Maps, and when coming out of doze.
Is there a more conclusive way to figure out what is causing my Nexus 5X's occasionally brutal performance?

Well, what exactly are you doing with your phone that's causing it to throttle itself? I think with a stock kernel the phone begins to throttle and eventually shut off the Big cluster at 36 or 37 degrees Celsius (someone correct me if I'm wrong). If you flashed a custom kernel, most here have had that limit raised to 46C.
Last weekend I used my phone quite a bit for strenuous tasks including Navigation, Google Maps, lots and lots of pictures and 1080P video. The phone got noticeably warmer, but when I checked my kernel management app, the CPU temperature wasn't even close to the throttle temperature. Unless you're gaming or constantly benchmarking your phone this really shouldn't be a problem. Especially when coming out of Doze. The phone doesn't immediately enter Doze, it waits a while and there are factors that play into its decision to even enter doze in the first place (like laying on a flat surface for X amount of time). So when a phone is exiting Doze because of your input (turning the screen on) the CPU should be quite cool (maybe 22+ degrees). There's no thermal throttling there. The Big cluster shuts off when the screen is off for the sake of battery life, so maybe the lag that you're experiencing stems from the lack of the Big cluster being on for the first second or so when waking the phone back up.
I'll agree that the SD808 isn't a stellar chip; maybe even embarrassing. It's not blisteringly fast, but it certainly isn't slow. There are ways to speed up performance and improve battery life at the same time, which I'm sure you'd appreciate. Unfortunately you have not specified if you're running a custom ROM or kernel, so that's pretty much all the advice and information I can give you right now. But, if you're currently running stock, I'd highly recommend you unlock your bootloader and try out some of the custom (and more lightweight) ROMs that this community has to offer as well as some great kernels. That should make a noticeable difference right off the bat. Then you can dive into the nitty gritty details of tweaking and whatnot if you desire. Check out the links in my signature as a starting point. If you're looking for optimization and speed (like I do) then you'll be impressed.
Thanks for your reply.
I switched to ElementalX about a week ago and it may be a bit better now but it's hard to tell. I've also been using a spigen slim case, maybe that is causing heat to accumulate too.
I don't game. My usage is Maps, Facebook, Snapchat, camera, chrome, hangouts, Spotify, and textra.
I use greenify and amplify as well on xposed. Disabling xposed doesn't seem to make a difference.
Can you confirm that ElementalX throttles at 46C and stock at 36C?
I'm interested in your recommendations. When running geekbench it takes about 9 minutes for things to really slow down.
Sent from my Nexus 5X using Tapatalk
If you search the ElementalX thread you can see that the developer, Flar2, was getting very frustrated with the thermal throttling on this device (others were too, as well). You can read through the progression and, eventually, the decision to apply a "thermal fix" or raise the thermal throttling limit. The threshold is 46C now. Confirmed. The stock thermal throttle threshold is 10 degrees less than that from what I've read. I also remember reading that Franco did a fair amount of research into the throttling issue and found that the CPU was capable of going over 50C with no issues (but aren't recommended), so the limit in place now by the ElementalX kernel is a safe one that shouldn't be exceeded. He probably didn't make it any higher so he wouldn't be found liable by any users if they overheat or damage their phones.
I have no experience with xposed and everytime there's a compatibility issue, hard reboots, etc. it's always because of Xposed. So.. Yeah.
I also do not use any tweaking apps that supposedly save battery or whatever. I let the operating system take care of that. I do use the L-Speed app (again, in my signature) to disable certain things like debug logs and what not to speed things up slightly. Again, I highly recommend trying Ubermallow and Phasma Kernel as those have been my choice, after trying many others, for some time now. Also, I'd look into the interactive governor tweaks after you've settled on a ROM and kernel combination that you like. That's where you can fine tune the way the CPU governor on the phone behaves and can really make a difference in battery life and fluidity of the device.
Lastly, a case can make a difference with cooling but I've never really found it to be an issue. Maybe I'm just not hard on my phone enough.

Google just agreed to take back my device so I only have a few days to try things and make my decision on whether to keep the phone or not.
Thank you for your thoughtful responses and suggestions.
Since I started using the phone outside of the case it actually seems much better.
Regarding the extreme slowness coming out of doze, it only occurs when in doze for a long time. Presumably because the phone tries to catch up on all the sync activity that's been paused for the last 12h or so.

I think I'll try your suggestions and remove greenify, amplify, and xposed to see if things improve. I do agree that the system should be managing those things.

Yeah, give it a few days. There are many ways to combat the throttling. Got my phone to 41C today while using it out in the sun. The Big cluster is limited to 633MHz at 36C and shut off at 41CC. The 46C built into the kernel is most likely for the LITTLE cluster to start getting throttled. Check the attached pics below.

ROM and Kernel are in my signature. The app for managing the kernel is Elementalx Kernel Manager and the app to add CPU usage overlays and stuff is called Trepn Profiler.
Sounds like the opposite to me, the phone might be slow because of software on the device not playing nice which causes the SoC to work over time (normal computing + rogue app computing) and can cause the device to over heat and throttle.
There's no reason the device should be slow after a period of doze. That tells me the device is having software caused slowdowns that are not related to thermal throttling.
It takes roughly 12 minutes of 100% sustained load (only synthetic benchmarks) to throttle the 2x A57 cluster, and I've never seen the 4x A53 cluster throttle under any conditions including hours of heavy gaming they stay at 1.4Ghz at all times.

Yesterday I was using GPS to drive and Spotify was streaming. The phone got really hot and unresponsive and Spotify began to stutter. Was unable to even launch textra to text someone.
This of course only started maybe 10m into the drive. The phone is fine while cold.
Maybe I have a defective device but my benchmark stress tests give similar results to other people.

this is consistent with my experience. GPS and spotify (actually almost any app used concurrently with spotify) will cause the phone to have horrible lag.
also, don't text and drive
Interestingly, today when the phone was on battery saver it seemed much faster. Maybe more throttling could help things more than less?
Of course not exactly faster, but more consistent and no unbearable lagging.
Yesterday I flashed the stock firmware files other than user data. Unfortunately I lost root and it seems like I now need to reformat data to get TWRP going again but until then I'm fully stock. Does anyone know a way around that?
I haven't done enough testing to be sure but things seem to be running more smoothly for now than they did with root and ElementalX 1.06. However just writing this i can feel the phone heating up and becoming less responsive. The bottom 2 cores are offline with SoC at 36C and CPU at 56C when I switch to devcheck to check. Other 4 cores at 1440MHz.

I've been having issues with thermal as well. Installed ElementalX along with the governer tweaks GhostPepper profile. When charging (this makes the device really hot) music begins to stutter, coming out of Viper4Android.
When not charging, slow accumulation of heat makes music stutter, same software used. Go figure. Maybe V4A is too demanding on the 808 chip, but I fear if this doesn't cut it, then I'll have to switch phones the next chance I get.
Oddly, this happens when screen is off - the music stutterings. I've thought about Doze and battery saving apps, and have disabled Doze for V4A through the battery optimize pane.
The phone constantly loses battery, around 2~5% an hour, I know thats not too much but my previous phone lost about 1% every three hours. This was a Note 3 Neo by the way. Installing Xposed and Amplify, Greenify and PowerNap should help, but I've had stability issues when using xposed. Maybe later.
Oh, and one last thing. My phone's thermal limit is set to 55 degrees Celsius, but it still feels like it throttles at around 39 or so. Maybe EX Kernel Manager isn't saving the changes, but either way... It throttles too much!

That could be because of the custom software and CPU tweaks or your V4A installation. Using those settings always has the potential to cause issues and I would troubleshoot there first.
Minimum CPU performance with stock settings is 4x A53 cores at 1.44Ghz which is still fast. If you've ever use one of the more recent Moto G devices you'd know it doesn't stutter playing music when it's cold and neither does this device when it's hot.
