[Q] At what temperature is normal for this phone ?

When I play games, it usually goes to 40 ~ 42 oC
Is this normal ?

Yes

Hum i thinks 40/42 is little high :s
or with big utilisation (HD games and wifi)
I have 26°C or max 30°C for an "normal" utilisation (sms and phone)

I've had up to 56C

It goes hot, especially when charging the phone while using 3G internet or HD gamming, I don't know the temperature but it feels bad on the back side, even have a problem holding it with that heat

Aaa, people, you know that you got no fan in your phone right?
The electricity in your cpu at top hertz rate goes to processing and calculating, but thw rest goes out like heat.
Like a lightbulb, 7-10% to light, the rest to heat
Conclution, the temp. is normal

i got near 42C so it's normal

Yep i have the same problem with my arc, but it's more warm when i use gps. And after too high t° the phone switch off and reboot, with any kernel,rom, OC or not... so go back to sony

Is there any application to measure the temperature, and what about the hang and reboot behavior with the overclocking? Can we control this?

My Arc's temperature is around the 23°C
But when i play a game or surf the net it goes around 40°C
I think it's normal..
Lucky it's not an iPad..

Mi5s starts throttling at low temperatures

Hello. I have noticed that my mi5s has some lag while playing asphalt 8 even at medium settings. After doing some benchmarks with 3DMark I realized that there is a drop in performance at relatively low temperature.
At "Ice storm unlimited" I have a score around 30,000 when the cpu is cool. However when I hit a 36 degrees of Celsius I am around 27,400. Furthermore, if the temperature increase at 39 Celsius , the performance drops even more and 23,500. This gets even worse when I hit 40+ Celsius where the score drops under 20,000 and if I semi-covered it with a cloth to reach higher temp it gets around 16,600 at 45 degrees of Celsius. After that it need to cool down to 33 degrees of Celcius to restore its performance
Needless to say that these temperatures are very easy to reach when you are playing a game. Has anyone noticed something similar? Any suggestions?
I have the 3/64 version with the 7.7.20 developers. Same issues were faced with the 7.7.6. . I have not tested in depth with the global rom but I think I had similar issues (it was only for a day). The room temperature is around 30 degrees of Celsius.

If you're okay with the high temperatures then you could disable all the CPU thermal throttles from any kernel manager app, though you need to be rooted.

I was thinking something similar but I do not want to disable it fully but just increasing the threshold by 2 or 3 degrees of Celcius. I am rooted but I am not sure how I can do the modification. From some quick search that I have done there should be a file named thermal-mplampla.conf (I do not remember the exact name) where you can modify it but I am not sure by how much should I change the respective lines for just a 2 or 3 degrees increase.
Anyone that have been playing around with thresholds and have any tips or guide before messing around?

First of all, that isn't the CPU temperature but the battery temperature. This phone actually has fantastic thermals due to its aluminum back and well placed SOC. No wonder you're getting throttling, you live in 30°C and you're playing games, what do you expect? Every phone on the face of the earth will throttle to that level. Just saying, your CPU is running probably around 70-80°C while playing intense games. So if you continue to play, it will eventually heat up the rest of the phone.
40°C destroys a batteries lifetime and 45°C everyday will reduce your battery within half a year which is why they throttle phones. Hell my One plus 3 in 30°C weather will throttle like crazy and that's the best phone in terms of throttling. Its normal. Stop playing crappy games like Asphalt 8 in 30°C and go enjoy the sunny weather instead.

Actually the truth is somewhere in the middle. I have used an app called "cpu temperature" but if I check the battery temperature it shows exactly the same degrees. So I guess it mistakenly shows the temperature of the battery. Do you have a more reliable app to check cpu temp?
On the other hand, 30 degrees of Celcius is not that high. In the winter usually we do not let the room temperature drop under 20 degrees since we use heating. Nevertheless, I will let it as it is for now and check again after 5 or 6 weeks where the temperature should be cooler.

You need a rooted phone to see actual CPU temperature. The best way to do this is get an app called simple system monitor (blue app icon) and go in temperature zones and you'll find a bunch of sensors there. There's a bunch of them that are for the CPU and you kinda have to figure it out yourself (I don't know exactly which one it is, one of the tz_sensor ones) by running a CPU benchmark and finding the ones that show the highest temperature. If you were to remove thermal throttling, and maxed out the CPU and GPU, you will see your CPU hit around 100-110°C and your phones gonna shut down for protection. And I'm in Canada so 30°C is extremely high haha.

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Sony Xperia XZ Premium stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!

Mine has not yet heated at all! I have used Zarchiver to zip and unzip, several large games (modern combat 5, order and chaos 2 etc). Even in direct sunlight, the phone only became luke warm!

same story...this phone remains cold. in every condition.

for me it it the coolest phone i have ever had

I live in a tropical country, so the ambient temp is high most of the time. Despite that, my phone only gets really warm, but not too hot. Very impressed with the thermal management on this phone.

I just got back from Mexico. Jumped in the pool and didn't realize I left my phone sitting in the sun. According to GSam Battery Monitor, the temperature of my battery was at 50 degree Celsius and it was only luke warm to the touch. Very impressed. I was scared for my battery tho lol

i play Clash of Clans on my XZP and see the temps getting as high as 106 degrees. It's pretty warm in the back. Not sure how anyone is really able to say theirs is "cool" all the time.

PC is not cool when playing games. Why would be XPERIA XZ Premium cool when playing games?

Because its cpu's tdp is under 5 watts with the integrated gpu while a pc's cpu could easily go over 100 and have additional gpu and other heat inducing components around?
Don't get me wrong, many phones get hot during intensive gaming and that's not a huge minus considering they don't have cooling. Sony's done good job with it and it's on par with other flagships with sd 835 considering it's a pretty efficient chipset. It's just that the comparison you made was out of place.

Mine does get warm sometimes, but that's it. Just warm.
My old G3 used to get really hot near the Power/Volume buttons when gaming or running VR apps.
It's the kind of hot where you notice it, but it doesn't really bother you. Unlike my G3 where I had to move my fingers away from that area.
More importantly, it hasn't stopped an app or lowered the brightness due to heat yet.

Omg 50.7 dc

My phone can get hot doing VR stuff, but otherwise it seems near impossible to get it hot unless it's a very hot day and I'm out in the sun.
Then it's possible to get the camera app to warn about heat, although this has never actually progressed on to the point where the camera shuts down. Not like my Z3 where 10 minutes of photo taking and that was your lot.

The phone is amazing, I manage to record 4k videos more then 30 min and phone didnt need to turn off cus of heat, like on Z5P.

Mine only gets warm when viewing 4K Youtube HDR video

Never had this phone overheat. Even when video calling over 4G.

pretty cool always, can get warm but only warm
in love with it, snapdragon 835 does the trick to prevent overheating.
although when viewing 4k content or in 4k mod it does get hot, but hey which device wouldnt showing 4k? im impressed

i live in Jakarta,Indonesia and my XZP only gets hot when the signal is weak.other than that the device is around 30 celcius to 37 celcius.

Well to add to this conversation , Got this phone and regarding heating it heats for sure in some situations, but not as much as Z3 dual in same situations (my previous phone) and I am not worry about heating as Z3 dual heats a lot when playing pokemon go on sunny days during summer and never had heat warring except playing same game in background while recorded HD video of car crash in front of me, that is only when I got heat warning on Z3. On XZ premium same situation I could feel some higher temperature in hand, but not even close to Z3 , and another worst situation is game pokemon go and mass evolving in game (who knows what is it) it brings Z3 to very high temp, while XZ premium gets up to with temp enough to be able to feel it. Zip large files with password 128 bit encryption or unzipping does not produce any heat on Xperia XZ premium, overall it is very cool phone.

My phone does heat when playing games like Shadowgun Legend and Modern Combat 5 but I didn't notice any throttling.

Mine was hot while i was filming 4k in a 34 degrees outside in the sun.
i simply solved it by dipping the phone in the pool voor 10seconds and it was fine again. made nice videos

Mate 20 x overheating

I'm facing an extreme overheat in top of the phone and when i use cpu monitor to check cpu temp sometimes it goes to 52 degrees in normal use ( browsing)
i tried software solutions none of them worked
I think that my cooling system is damaged
Can anyone help me please ?

Hmm, rather strange. I can game a extremely graphically demanding game and my baby stays cool, as soon as I leave the game temps starts dropping fast

Question Random 100% CPU usage while gaming

I don't know what to do, every time I play Asphalt 9 or COD Mobile the first games go very well but there comes a time when the CPU reaches 100% generating FPS drops (Despite using an External Cooler)
I mention the random thing, since I can play several times in the same scenario (in the case of Asphalt 9) and the CPU usage reaches 100% in areas where in the previous games it did not reach 50%
What do you recommend to solve this problem?

can be cpu frequency drops in case of overheating.

Maybe your phone is overheating due to high usage of games and check if there are background running apps, it can also consume Ram usage.

When I go to play I close all the applications and limit the background processes, but still excessive CPU usage still happens :/
Also, I play using an external cooler, Which keeps the temperature of the phone below 38°C

I'm running stock Kernel and stock ROM (No Root), should I root and try TDP Disable?
