What kind of temperatures do your XTZs read? - Xperia Tablet Z Q&A, Help & Troubleshooting

I'm probably just paranoid but I think I've been feeling my XPERIA Tablet Z being a little warmer than usual. Average temperature readings by the System Tuner app off Play show the chip running around 42~52 degrees Celsius. As such I'm interested to see what kind of CPU temperatures' everyone else's tablets are reading?

[Q] carcassonne cpu usage

I've recently purchased carcassonne from the market and while I love the game, it does seem to eat up the battery pretty quickly. So i'm wondering if its just me or are other folks experiencing this too?
Bit of background, i'm running Cognition 1.51 on an sgs2 and while playing the game it looks like it consumes around 58% (average) cpu. This to me seems excessively high. Carcassonne for those that are not aware of it is a tile based board game, which doesn't seem to me to be a candidate for a fast cpu. Yep, i could understand that the AI might require CPU but surely not for the rest of teh game.
So question is, does anybody else have the game and do you notice high cpu usage on it?
I didn't play that game but 58% consumption after how long playing? Do keep in mind that a playing a game is CPU intensive task, so CPU will be hot and battery will drain much faster than other stuffs.
Regards.
Ordinarily yes I'd agree about games and CPU usage. But for this type of game I'd expect it to have very minimal requirements.
Also I started up a fresh game and left it waiting for me to play my turn. Leaving it waiting for twenty mins and when i checked utilization it was still 30%. Given that there was no animations or screen activity that does seem excessively high.
Am trying out miui rom now to see if that makes any difference.

Z2 CPU temperature and heating on your phone

Hi,
since I updated my Z2 (D6503) to LP 5.0 my phone is heating pretty much. After 10 min. of using (doesn't matter how) temp. foes up to 38-39 degrees of celsius, and after using for a while like an half hour, it goes even up to 41-42 degrees (but it is also very very hot in room in which I use it).
So, I just wanted to hear your opinions about this, is it normal, do you have the same issue and can it be corrected somehow?
That's all, thanks in advance to all.
Mine's CPU almost hits 70 degrees celsius. Your temps must be battery temps, cause mine are the same.
38-42° Celsius? You mean Battery temperature right? My phones CPU was about 58-66°C after installing 5.1

Peak CPU temp under load.

Hi, what is the normal peak CPU temperature for the phone? Mine is going above 90 on the antutu stess-test. I feel it pretty hot around the back camera. Is this normal or my unit is faulty? Thank you.
Is that degree fahrenheit or degree celsius?
Hi, it is Celsius. Please note this is the CPU temp. The battery temp was in low 40s at that time.
Could anybody please run the 15 minute Anutu stress-test and check where the CPU temp goes in Celsius? Thanks!
I've seen several videos on YouTube, the temperatures never raise above 45 degrees celsius, even after an our of playing PUBG. So I think there's definitely something wrong with your device.

It's odd but I have bad experiences with the older 800 series of Snapdragons. I'm still holding off Pocophone for the SD636 or SD660 until I'm sure it doesn't lead to me frying an egg with the phone after playing for 30 minutes.

Playing youtube 4k video and the CPU is around 40c as well. Please note these are CPU temps I am talking about, not the battery temp which is in low 40s when the CPU goes above 90.
If possible please run the antutu stress-test for a couple of minutes and advise on the peaks. Thanks!
Just played pubg for 20 min on the default settings - CPU temp peaked at 46 C. I guess this is normal but why does it spikes in 90s on the antutu stress test...
Run Antutu test again 264k, temp spiking in 80s here in there at the end was 33 C.
Please advise if this sounds normal.

That 80c spike has got to be erroneous. That's 176F, which would melt the back cover and everything else inside.
yes it is true
I have the same experience. Run antutu and watch the temps using CPU float when it starts the CPU benchmark. Boy, it went all the to 95 C then goes back to 60 and 90 until the cpu part is finished. While gaming, this wont happen as the cpu will throttle depending how hot the battery temps. I posted the thread here at https://forum.xda-developers.com/poco-f1/how-to/phone-throttles-cpu-gpu-t3839525 so you can see the effect of battery temps on cpu performance.
My question is more like how antutu's cpu test really stress the phone. I run HWBot with cpu float and the maximum temp i was able to get was like 70-75 C while antutu can shoot the cpu up to high 80's to 90's in even cold phone state.
I think it is due to the fact that most of the companies optimise their software in such a way that the benchmarking apps consume the full CPU usage regardless of thermal throttling. OnePlus did this with their phones. My old leeco phone had the same optimization that it automatically utilized full CPU power in benchmarking apps. So I think similar is the case with Xiaomi's Poco f1
Poco F1 cpu temperature reaches 96 °C in Antutu

Mine too.It goes up to 96 C , then 60+., 70+ then again 96 degrees Celsius in Antutu stress test.
And in heavy apps goes beyond 60 °C.
I bought the phone from Romania, where I live.
I have a different problem, i too use poco f1, my benchmarks are around 4500 at 36 degree celcius wheras it is 8000 at 30. So is it the same with everyone?

Performance Throttling Overheating Device Temperature

The lower scored benchmark is at from idle of around 40C (CPU temp) while the phone is in the room. The higher scored is when I placed my phone in the freezer and let it cool down to around 28C (CPU temp).
Why is the phone so hot even at idle? Do you r phones go as high? What are your ambient temperatures? I'm in a tropical country and it is around 29C here right now.
The battery temp is only a degree or two lower than the CPU. It's terrible for the battery to be at this temperature.
Mine is around 36 C after 30 min of browsing . inside room temp is around 22 C.
Yeah, Mine also get so hot like 40 -45 like your after 20min of used.
But our Poco got cooling system right, then why like that?
My previous Moto z play was not like that ?, It was only heat while charging because of rapid charge.
It's coz of that garbage of IU called MiUI. Every update it screwed something.

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 Samsung Galaxy Note 10+ 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!

The heat pipe system in it works very well... this phone should never run hot. If it does, something is wrong.
Mine needed extensive optimization to run cool... it's my favorite phone now. Like having a laptop in my palm. Avoid "upgrading" to Q, it's a nightmare.

All phones with good cpu/gpu get hot when gaming for long time.
There is not any thing wrong with that.
Exynos phones get very hot ingame, cpu temp can go up to 70c.
If your note 10 don't get warm after 1h asphalt 8 there is something wrong with it like low fps and or trottle.
Batteri temp in heavy game around 40c
Cpu temp in heavy game (Exynos chip) 60c-70c.
Your phone will be warm..

Talking about unwarranted running hot. dah.
The hottest my phone has reached playing games was 45°c. But it mostly sits at 43°c when gaming. Is that good?
Too hot

No.
107 F is too hot*. This isn't a desktop cpu; running an LI battery this hot will greatly diminish its lifespan.
Some of the CPU heat plus the extra current drain heat the LI bat up. I never let my battery temp exceed 103 F when in use or 100 F during a charge. >85 during charging is better.
Put a damp rag around it or on the backside if in use to cool it if the ambient temp is too high...
*43 C is fine for CPU temp as long as the battery isn't getting baked. F is easier for real world temp measurement.
My cpu and chips are running at about 104 F while the battery is at 95F; the ambient temp is about 90 F, acceptable.
This with a light cpu load with brightness at about 40%
For heavy cpu usage at these temps for more than 10 minutes would drive the battery temp unexceptably high without external cooling.
Monitor the battery temp. Lol, if the phone feels very warm/hot it's damp rag or shutdown time.
F is easier for"real world" ? F are only used in ONE country! Which, by no means equals ALL the world, science, real science uses metric system

The Fahrenheit scale is centered around the temperature zone most used by humans.
A 10° F isn't too much a of a change but modest amount.
A 10° C change is huge.
It's ackward to use in real life... suffer.

Good thing you don't have the Exynos version.
The idle cpu temp is around 50c with about 20-25c room temp.

122 F is really hot for a cell phone... a very expensive hand warmer. When a phone feels hot; it's already too hot. This will greatly shorten LI life especially if above a 90% charge.
Current drain* at idle with 50% brightness level should be below 220 ma. Typical idle current on this one averages at 140-200 ma.
If it's running >400 ma, something's running in the background sucking the life out of it.
I use different temp apps. Been playing with the Gitlab one.
It's 26.6C (80 F) ambient temp here and the CPU is averaging about 35.5 C (96 F) as I'm using the Note.
Battery temp is the only one I need to really watch.
I monitor that and battery current drain.
*AT&T variat, not rooted but heavily optimized.

exynos is running hot, there is not mutch you can do.
Here is one example
https://m.youtube.com/watch?v=LfZUNL5hyVw
If you pause the video when he start antutu you can se the cpu temp of the s20 ultra (about 56c without any massive load).
My old s8 with exynos got warm and it worked just fine for 2 years, sure i lost a few % on the batteri.
After 2 years just get a new batteri and enjoy.
I know snappdragon is running mutch cooler, but make sure you get a app that show the right temp. 35c in a 26.6C room sounds like idle temp at best.

For you Fahrenheit may sound "logical" as you grew up with it. For us - the rest of the world - we grew up with Celsius. We don't need a scale "centered around a temp zone used by humans", we know what effect a 10°C drop in temperature has on us...nothing ackward about it.

Unlike the metric system of temperature measurement it is uniquely centered in a range where most living occurs... 96.8° is a better way to index human body temp. One degree matters.

Update...
Trying out this temp apk:
https://play.google.com/store/apps/details?id=com.novelmatrix.temperaturemonitor
It will display in the corner of the screen real time. Low resource usage. Some ads on set up but liking it so far.
At 96° ambient I'm seeing the CPU, GPU typically going between 102-118 F depending on usage.
Browsing it's running between 100-102 F
Internet vid jumps to about 114 F at this ambient temp.
Obviously higher for cpu/gpu intense apks, haven't benchmark it yet with this running.
The battery is at 96.8 F and typically runs cooler.
The heat pipe seem to work well; dissipates heat rapidly from the cpu and helps keep the battery temp down.
