Hello all!
When I use my Z3C and doing nothing, I mean... just having the phone in my hand, slide between homescreen pages juste for... you know... when you have this sexy lady in your hand... just for looking
But even if I do almost nothing with it, I feel the back hot and my battery apps tell me that the battery is more than 40 degrees. Just for better results I downloaded the app "CPU temp" or "CPU-Z" and it tells me that the CPU is at 45 degrees.
And when I play games the back is more hot!
I just want to know if it's normal? If your Z3C is hot too. I know if I play it's hot but if 40 degrees just for using it with normal apps (Twitter etc...) it's normal?
Can you make some quick test, download CPU-Z and check the "thermal" tab for example or what you want?
For more simplicity in the thread, if you want and if you can, download the app CPU-Z and post the result of "thermal" tab here (just the first line temp), thanks!
And I even see videos of AnTuTu benchmarks on YouTube and the Z3C is at 47xxx... but my Z3C is always between 43xxx - 44xxx ... I don't know if it's the same problem. What scores have you in AnTuTu?
thank you all!
(My phone is STOCK and completly clean, just hard reset before test temp)
my phone is always on 50+ celsius but i think it's normal. it happen on LG G3 too
After about 15 minutes of gaming, my sensor says 40.0 c., but I also have my CPU downclocked by a lot to extend battery life by huge margins. Stock setting puts the CPU frequency at 2.5ghz, and I have mine downclocked to 1.0ghz since I didn't see direct impact on performance with the games I'm playing (mostly emulators or GPU-dependent games).
tsens_tz_sensor0 is the highest at 40.0 c
msm_therm is the lowest at 32.0 c
At stock settings though, my phone runs at 50.0c on average, and it heats up about as much as my Galaxy Note 3 when they're playing the same games. For awhile, I thought the Z3c just heated up more than other phones, but after playing with both phones at relatively the same time, I realize that's pretty much just in my head.
Oh, forgot to mention. Also running on stock 5.1.1 that's rooted, debloated, xposed with greenify and amplify, and a custom Luxx profile to manage adaptive brightness.

When I bought Xperia T, after a while, I started to be a little disappointed with performance, autobrightness, discharging when playing, etc.
After some digging deeper into this problem, I have found, that cpu is throttled by temperature. And not only the cpu.
A few minutes of playing game, cpu goes to 800MHz, display brightness goes to level 100 (max. is 255), wall charger current is reduced (even when connected, it is discharging), radio power is reduced, etc.
Change it yourself:
Example:
xo_therm 14 -1000 380 20 NOTIFY CAM_NORMAL cpu_perflevel:1728000 charge_current_limit:0 usb_current_limit:1 modem_level0 lcd_brightnesslevel:240
xo_therm 14 = sensor step
-1000 = -100,0°C
380 = 38,0°C
20 = don't know (maybe some kind of sample rate?)
NOTIFY CAM_NORMAL = obvious (camera)
cpu_perflevel:1728000 = cpu frequency
charge_current_limit:0 = obvious (0 is 1300mA I think, 1 is 1100mA, 2 is 900mA, etc.)
usb_current_limit:1 = obvious (has impact on charging too)
modem_level0 = power of modem
lcd_brightnesslevel:240 = obvious (0 - 255)
Set the highest temperatures, with low enough frequencies and charging current values, to let phone cool down.
"gpu_perflevel" can be used too and there are some other thermal sensors in sysmon.cfg, which are also responsible for thermal throttling.
Disclaimer:
Each device is different and I am not responsible, if your device burns with some values from here.
Both CPU cores always on:
Echo 1 in /sys/devices/system/cpu/cpu1/online and change permissions to 444. And if you want to prevent errors from log (and maybe some unwanted wake locks), rename /system/bin/mpdecision to something else or delete it.
what is temp at what cpu throttles (and other things)?
seems it is lower than other devices, something like 40C, i think my sgs3s was at 76C or similar.. not sure, will check later.
sgs3 was a very hot phone.

You can see the temperatures in sysmon.cfg - xo_therm 400 500 = 40 - 50°C for example. Cpu temperature, not battery. There is no tool to monitor cpu temperature, but if you set your own frequencies, you can see with Cool Tool, how long it takes to the lowest frequency.

thanks, will check. i am on cm10 and didn't notice throttling yet, but i will check now as it is ****ty if so.

I have noticed the throttling but it doesn't affect the performance in my case, playing games and watching HD video are fine, just annoying when the screen suddenly does dim.

@OP:
If you don't want throttling, uninstall Androids inbuilt Thermal monitor(No need to tell you the risk by doing that I guess).
Thanks for you valuable advice.
Don't think it would help as that file says 2nd core off values are hardcoded

I think, that it works, because I tested it and I am using my own values.
Good thing I won't be playing games when my T will arrive

Still? Damn how long do they take ? -.-
Here is the .apk of the old version. No idea how much works and what doesn't!
Hello,
Could it be some kind of default on your device ? or maybe the application ?
Cause I remember Qualcomm's communicating on their S4 being "cooler" than its opponents when under heavy load.
Can someone else confirm ?
What's strange is that the game you mention (Osmos HD, which I bought some time ago for my TF101) does not even use super high end 3D graphics etc etc ... maybe the perf drop could come much quicker with some cpu/gpu intensive apps.
If confirmed, it might even become a big "no go" on this phone for me.

I've had this phone for a while now and I haven't had a bit of lag while playing any game I have. Everything seems fine except the sudden dimming of the screen when playing games. Don't let this put you off buying the phone, its a great phone
Edit: been playing Osmos HD for at least 25 minutes, I'm experiencing no such lag or performance issue. Only the dimming issue I seem to get.
Well, after some more investigation, I have found, that lags in Osmos HD are not caused by cpu throttling, but wifi disconnecting.
Playing the game is fine, but still, with default settings the temperature is going high and except the screen dimming, cpu goes to 800MHz, (1 core disabled on highest temperature), and phone is discharging even when connected to wall charger.
It seems to me, that the overheating is not caused that much by cpu, but gpu. It would be nice, if it could be tested somehow by lowering the frequency of gpu.
I wonder if the heating issues could be fixed with software patches. Given Sony's desire to incorporate playstation stuff, I find it hard to believe there is some sort of hardware issue.
Wish we could get some more samples to work with.

Just measured with my settings (in the room - about 23°C):
10 minutes of playing Osmos HD without charging = 62°C CPU temp
With one core running on 1350 MHz and LCD brightness value 150, it's not increasing anymore.
When charging, the temperature will go higher. I will test it too.

Have you tried treppn profiler?
Anandtech says a CPU core draws around 450-750mW while gpu goes 800-1200mW!
Seems like 400mhz is a hard Task for an 225.
If you are still on ics maybe try jellybean? Perhaps project butter may more efficiently handle the gpu.
Maybe even make a list of "stress test" for people to try and see what the various results are.
If all else fails try undervolting the gpu and cpu.

Yes, I tried trpn profiler provided by you, but there are limited options.
It looks like the GPU cannot handle this frequency.
Undervolting won't help anything, but lowering GPU frequency would help I guess. But this cannot be done without custom kernel, allowing this.

Same here. I've been playing Speedball 2 and GTA3 mainly but I have played a few others too and haven't experienced any lag and no performance issues observed at all.
Hello guys!
This is my first time posting here, so if I'm breaking any rules please let me know
Anyway, I'm looking to get a new Android device and I'm think I'm going to get the new Sony Xperia Z. The only problem is that I can't get a real device to test it (for just like 30 minutes). Anyway, I've watched a bunch of reviews and read many articles so I good to go, except for one thing - I want to know how much the phone heats when it's running at 100%.
I've already seen some threads here on XDA, but they are mostly subjective (temperatures are mentioned as warm and hot). I would like to get more objective result. If you own a Xperia Z device, you can help me - it won't take too much of your time
Anyway, here is what I'm proposing as a more objective test:
1) Download and install StabilityTest i System Tuner. You can get them in the Play Store.
2) Close all running apps. Run System Tuner. Open Settings -> Recording preferences -> Items to record and check CPU frequency and CPU temperature.
3) Go to the main menu of the System Tuner app and click icon named "Start" (upper right corner). Now the app is logging the in CPU frequency and temperature. Click on CPU icon and not your current temperature.
4) Leave System Tuner running in the background and open StabilityTest. Click on the first button (Classic Stability test). Leave it running for at least 20 minutes.
5) After at least 20 minutes have passed, you can close StabilityTest and stop recording in the System Tuner. The log will be saved on you SD card in the folder pwm/recordings. Please attach it in you post
Please post your battery percentage before you have started StabilityTest and after you've closed it. Also, please post whether you did the test with you phone on or off the charger.
Thanks!

You don't need all this benchmarks because its common sense really. I have the device, on normal operations e.g. browsing, videos etc.. it doesn't get hot, but a bit warm near the rear camera. But, if you do intensive tasks e.g. playing a game e.g. nova 3 etc.. then it gets a bit more hot, but not so much to burn your hands. This is normal because think about the horse power this phone has in a slim form factor and all the heat that gets generated without any cooling fans. Its normal but its not normal if it goes beyond the range of operations, which in my case, I have not noticed. I had a Motorola Droid the keyboard version, that device got extremely hot and it was really uncomfortable to hold.
As a user, I am very pleased with this smartphone and ofcoz it has drawbacks then again no phone is perfect. Hope this helps what you looking for without benchmarks

Transitioning from a low end HTC Incredible S, I found it very unusual how the phone got warm by just going through the user interface.
then i ran qualcomm trepn profiler and it showed that my 1st cpu core was doing anything between 1ghz and 1.5ghz at any given time.
possibly fixed with a kernel tweak?

It should be common sense, but I've read about Xperia Z on many pages. And some users say that it only gets warm, others say it's hot when gaming and some say that it's running too hot. Maybe some of them do have defective units, so this test would be also great for comparison between units. Can you run the test? You don't even need to run it for 20 minutes, 10 should be enough. Or if you won't/can't do the test, can you at least just check in the System Tuner if Xperia Z has CPU temperature sensor - if it doesn't have one then I can stop searching for people who own it.
P.S. Can somebody say if Xperia Z is running hotter or colder than Samsung Galaxy S2?
so i've been playing Injsutice: Gods Among Us with mobile data (for me to logged on and to access daily challenges), after 20-30 mins of playing, the game started to drop its framerate and i felt the phone is hot. I exited the game and i accidentally press the camera icon, to my surprise, the camera says something like, 'You can not use the Camera due to high temperatere...."
so i installed elixir and cpu-z for me to know the temperature, after several hours, i tried again to play Injustice with mobile data off, the phone became hot after 40minutes of game play and it has a fluid framerate and the camera works fine. the temperature was around 47C.
i cooled down the phone, and played with mobile data on, after 20mins the game drops it's framerate and the camera is not working again. it has a temperature of 49.6C
the question is:
- i know playing hd graphics keeps the phone hot, but is it normal to all z1 users especially when it's already forcing the CPU/GPU to lower its performance and prevent the camera from being used?
- do i have the right to get a replacement for the phone?
- have you also experienced this when gaming? especially online?
note:
- i'm running a rooted, locked bootloader, firmware .136
- underclocked at 1.75GHz

QuadCore running for several minutes means heat generally.
But beside what phone exactly do to control heat the apps u use are important too.
for example famous angry birds make my phone hot! But Fifa-14 doesn't!
under-clocking doesn't mean certainly u won't get battery draining or heat issue
it needs also compatible kernel
anyway heat issue is not always because of hardware cause there s also heat-controller (or sth like this) inside firmware that can working not so good and u should repair ur phone by PCC
to be sure if it s hardware problem and ask for replacement, first completely restock it.

try underclocking your cpu to 900mhz you'll notice no slowdowns in game but the phone will still overheat, that is because the GPU is causing the overheat and is the one struggling in games, not the monstreous CPU in the z1. you can try flashing doom kernel or AOSP kernel by android.fr to underclock your GPU.
The phone will get hot anyway, doesn't take much, but playing a hd game will cook the bugger. Never play when plugged in if you are, put your apps on a diet and get rid of anything that you can do without, lightening your load will help a lot. Personally I wouldn't consider it a problem unless its affecting gameplay. The drop in frame rate is the CPU clocking down to protect it, which is a good thing and quite normal. So you have a case on your phone? Try it without If you do. If the phone begins to shut itself down then that's a worry and you should certainly look for a replacement.
Hope this helps.

I decided to download Asphalt 8 last night to see how the Note 5 handles it, initially it looked good but after 20 seconds or so the frame rate slowed down considerably - I would guess less than 10 frames a second. I uninstalled it, cleared the cache, reinstalled but still the same issue. This is on High settings which is the default setting. It's like the phone starts to throttle after a short amount of time racing?
Is anyone else playing Asphalt 8, have you seen anything similar?
I downloaded AnTuTu bench and was getting over 60,000 which seems in line with other Note 5's and 3D Mark also seems to match up so i'm not sure if this is just Asphalt 8 or a bigger problem.
I installed CPU-z so I could monitor temperature and if I check it when the game is running slow the Exynos reports around 60c which doesn't seem that high?
i've only tried it on my S6e without any noticeable issues. do you have Power Saving mode off?
(Sent from another Galaxy)
Yup both power saving modes are definitely off.
There are drops in some games after minutes of gameplay, that because of Samsung TW DVFS, which basically monitors and throttles the CPU way too fast.
If u have root, u can set cpu govenor to performance when playing, that will eliminate all the lag, that what i do.
A month ago or so, i had this random period of time where perfZ started to show "-" for temperature ( i assume its gpu temperature because it doesnt match with battery or cpu temp from another app) and my phone was heating up much more in games but so was the performance was way better.
Normally after thermal throttling kicks in and device reaches heat equilibrium, my battery would sit around 38-39C, cpu at 42-43C. But in that time period where it showed "-", my equilibrium was battery sitting at 44C, cpu at 47-48C. Phone was considerably hotter to touch but you could still game on it. And performance was way better, it would fall to 50fps min instead of 40fps, which is very noticable. (Dont have exact numbers maybe a bit better)
Idk how this happened as it randomly happened one day but does anyone know how to make this work? My device isnt rooted. (s10+ exy)
(Small note: Using game plugins at max performance or custom doesnt help, maybe they arent optimised for dead by daylight, because thats the only game i play)
