Battery temperature

Hello all! I am running a simple battery app on my GT 2 7.0 that provides battery temperature. The highest I have seen thus far has been roughly 35 degrees Celsius. And an area of the tablet gets warm (not hurtful hot, merely warm). Is this a normal temperature for the battery? I am not familiar with the appropriate temperatures so figured I'd seek guidance from people with more experience, haha. I am not rooted or running any type of custom rom, just stock ICS that came on the tablet.
I am looking to get a case for when I am holding the tab as I find my hands do get warm while holding the tab, maybe that is causing the problem. When I had the SG Player 4.0, I installed a battery temp app, I noticed slightly warmer temps without a case.. I bought a case within that week and temps never went above 27 degrees Celsius, even when I was pushing the little guy a lot.
Any thoughts or suggestions would be appreciated.

weird
the case should increase temp. as it prevent heat dissipation sooo weird !!!

Elixir has a widget with small footprint so you can monitor it.
Mine never runs hot and I oc mine to 1.4ghz. Doesn't feel hot anyway. I use a case on my tablet.

Thanks for sharing the app and a screenshot!
It appears yours, during the time of the SS was running at roughly 40C.. And it runs fine? I suppose I get paranoid about such things, but mine never goes over 35C and doesn't stay that way for long periods of time.. Right now, it is running at 31C and I am locking/unlocking the screen quite a bit as I am using Facebook messenger..

35c degrees is fairly normal, but never overclock your CPU if you don't want to have your gtab2 dead for the next 2 years

What could I do to keep temperatures down if I may ask? I don't do heavy gaming on the tab when I do run games. I am mainly using the internet in some form - browser, YouTube, etc. Thanks for your input.

I've run several android devices overclocked for years. My old evo has been oc for two+ years. Kid I sold it to runs ics on it overclocked.
So do some research on the subject.

Well, I am not wanting to or trying to OC my tab as I am too much of a "noob" for that, lol. Just curious about the temperature the battery is running at and all.
I find that idle, the temp can be around 30 degrees Celsius.. this is somewhat surprising to me, but it's my first tablet as well, so I suppose I worry I will cause some sort of damage or that it simply has a defect of some type.

Antutu v6.0 is now available

Many years looking the same... but now antutu is completely redesigned and looks really nice.
You can now compare chipsets performance also ...
I know that lot's of people don't like it but many others do... I do!
Have a look... I bet you'll all like the new antutu...
I scored 69k at first test using Mokee
Just to let you know

41k on sMIUI 12.3

69K?! O.O
You make me want to try Mokee

44k on my overly crowded sMIUI. Looking at LG G4 score, we should be able to reach that point so 69k is the expected score.

Not sMIUI fault I believe, when it was still virgin I can manage 5Xk too on antutu 5. With aqua mail (3 accounts), facebook, hangouts, line, path, twitter, plurk, slack, whatsapp and many other background apps, it's hard to reach that score back.

Stable chinese MIUI rom 7.0.7.0, rooted and greenified. Managed 68500.
Sent from my Mi-4c using xda premium

66 668. I would prefer 2 points less

On sMiUI 12.10 my phone scored 65k. Forgot to take screenshot.

As States before... 69k on my Mokee... But... It is more 70k than 69... Anyway, what a machine

Ooops... 70K... Getting better! Now with a few more apps installed... So I guess it has to do with the ROM... The apps you have installed have nothing to do with antutu score i guess... Just saying...

Getting 47858 on CM12 on charger without restarting :/
Resetting and running in Airplane mode gave me 42k on charger
Running again without a charger gave me 58119...
Restarted again, ran on battery got 60070...hmmm

On charger phone got higher temps, and there is throttling.

Our device will get slower when it's hot due to thermal throttling, the thermal engine controls both CPU and GPU. When charging, especially when it's over 60%, the temperature will reach a high value that may exceed the threshold imposed by the thermal engine. Thus, either the core speed will be clocked down (CPU0-3 max 600, CPU4-5 max 864) or they will be totally off. Same with GPU (max 300 when hot, 600 when normal). I think Xiaomi didn't notice that many of its customers live in the equator lines where the temperature is generally warm to hot (25-35) so the threshold values will be reached much sooner than those who use the phone in norther or souther area.

It's true... But in this version of antutu the scores dont get uch a diferente after 2 or 3 tests... In previous version I used to get 57k, then 54k and then 50k... In this version I get 70k, 69k and then 69k again... Not much of a diference in results after heating... Why would this happen? I never get less than 69k

Maybe you need to put more background apps to your phone as I do
Having a screenshot of Android Assistant (both Monitoring and Processes tabs) might help the analysis.

Around 70k is a very bad score I must say, for our hardware.
On last Antutu I got 59k score and for example my friends Iphone 6s had 57k.
Now I'm getting 69k, and he is getting 120k scores.....

TBH, that's not bad since you can buy FOUR Mi4C for an iPhone 6s. Twister Core in Apple A9 is the best single core processor to date (which Snapdragon 820 Kyro cores might be able to beat when it comes out seeing latest benchmark info). Our Snapdragon 808 is even nowhere near 810, how could you expect it would beat Apple A9? Here's the official AnTuTu list for each SoC:

IPhone 6s with 57k... In your dreams. Mrkubix go to sleep...

Sd820 still does not beat iPhone single core performance... Dont know how they did that twister... But they did it very well... Typhoon was already wonderful...

Heating issue S7(Exynos)

As a test I played 'NFS No Limits' in my Galaxy S7(Exynos) for about 20 min and I felt hotness all over the metal sides especially more in the area near power button. Also the back of the phone was a lot warm for touch. Is this expected from the S7 even with the heat elimination method inside. Below linked image is the results I recorded. Kindly take a look at the CPU temperature as well as the battery performance throughout the test.
https://drive.google.com/file/d/0B60MJrdiGFpZREM4enF5VVduUG8/view
Please note that Game Launcher optimizations were no used.
Is everything fine based on the above results?
PS: Even watching YouTube videos(in native app) for like 6 min makes the device a bit warm with CPU Temp to 34C from 30C(Idle state). Still normal?

I just bought mine this afternoon and it was a bit warm when loading the updates which I would expect is normal when downloading big software updates. Right now it feels normal.

Well if you have time, please play and see how 'NFS No Limits' is on yours I see stuttering in game when there is rain. To measure CPU temp at regular intervals use this app https://play.google.com/store/apps/details?id=com.yanyan.cputemp

I repeated your test of NFS No Limits for 20 minutes using the CPU temperature app on a Galaxy S7 (Exynos). My results were similar:
Before test: 35C (it had heated up from 32C idle to install the game and app for the test)
At 7, 13, 17 and 20 minutes: 38C.
Battery before test: 35%
Battery after test 27%.
I also saw stuttering with the rain. The game was very smooth initially.
So very, very similar results.

ideal over 30c?? mine is under 27c...28-29c after 30min of browsing, yours seems defective or you are having rouge app thats using your cpu.

Seems similar. Still don't know why some guys are having better cooling.

38 is not that warm. My G906K would get up to 49 c while I was in the sauna and would not have a problem. If the phone gets too warm it will go into standby mode stating it needs to cool down

Op location? Dubai? Room temp 30c ?

That app does not show real cpu temp...

at best what you have is battery temp.
And that was just because google services starter acting up ( from 9 to 15% usage in 10 min, consumed 6% battery ), no gaming or heavy use.

The therm_zoneX values are in no way related to CPU as far as I can see from these pics(attached).

The CPU is the hottest thing in the device; therm_zoneX reads are 75, normal for a CPU under load, therefore they indicate CPU temp.

[Question]2 cores are working only?

Guys can you check in your phone how many cores are working at a time? I see only two cores working at a time and i think they are the slower ones
Any impact coz of this?

i have checked with cpu-x app and all 4 cores are working simultaniously

Firmware ver.? Single sim or dual SIM?

Ive noticed this aswell on 7.0, and my antutu score went down from around 139000 on 6.0 to around 127000 on 7.0. I would say its a huge performance loss. But real life performance i havent noticed any difference, but not in batterlife either so id rather have my cores back.

me too, since i switched back to stock build 39.2.A.0.327 benchmarck highest score i could get is 130355 and battery seems worse too, i used to have like more than 138000 and very decent battery life with Frago's Nougat Rom, so i've flashed it back on... no rooted stock build for me anymore i guess...

Same issue here, I tested with CPU-Z and CPU-X and is the same result, only 2 cores working.
Firmware: .327 (Nougat)
Region: Malaysia
Model: F8332
So, I think that is a bug of the reads, beacuse if you perform a Benchmark, the results are the same that when you use Marshmallow (with 4 cores).

Might be possible... I hope this is the case

No, i tested with benchmark software, it is 40% lesser mark compare the 6.0
I feel lag after updated to nougat.
And my old z3 is faster than XZ now.
Used to have at least 120k marks.

i'm on 7.0 nougat and on antutu i did 144.000. It's good? which is the best score for the xz?

7.0 39.2.A.0.361 Orange MCV FR/ES/PL/SK/RO
I was suprised to hear that so i've been testing my device with antutu, usually core 2 and 3 ( max 2150mhz) are off, but i think it's probably due to nougat update, once i saw them all working for a sec.
My scores are between 147k and 115k.
First highest score with rather cool device, room temperature 24C, WIFI, BT, internet connection, NFC, Auto rotation: OFF, screen brightness on- set to minimum.
After few tests device got hotter and scores dropped to about 125k. Then i tried to push it to the limit, all ON, screen brightness auto-set to max. Score dropped to 115k.
So throttling is there definitively. Score around 130k can show how device will behave in normal use and it is fast as it should be. In case of my device, battery life has improved but it might be placebo effect

After update to latest nougat, the another 2cpu is back, but only for some minutes.

I just updated the cpu-z, and it is showing all 4 cores working, at 2.15ghz can't make a screen shot because it is moving quickly to 1.5 or it stops.
Edit: forgot too say that I'm using stock rom, 7.0........ 39.2.A.0.374.

Checked and sadly I got the same problem :'(. Hope they fix it soon.

Um... So what kind of CPU load are you putting on your phone in order to make all 4 cores to work simultaneously? In other words, why are you expecting to see all 4 cores active in CPU-Z in the first place?
If your phone has nothing serious to do at the time, then even 2 cores being active is too much. You should see only 1.

I tried play high end game - HIT and switched to see, CPUZ still showed only 2 cores are active.
While after 30 mins-45 mins of playing, it became laggy and not responding until I restart that game.

You can also check your chip bin by going through the download mode. Mine is all 10 out of 15 I guess

Thanks for the information. What names you say snapdragon will be faster this year?
That battery life indication isn't realistic at all after all those benchmarks. Should be much better when using normally.
This year thought this phone is boring me. Mine comes tomorrow but i feel dead about it. Will probably go back unless battery surprises me in a good way

yep i usually dont use AOD but since i was busy benchmarking and some other stuff didnt tune the phone to my likings yet and AOD will definetly be off

looks like the NDA is up, reviews are flooding in for US/SD845 units

So first full charge today looks alright as it's the same usage I had on my s8 in the beginning minus AOD.

AntutuView attachment 4441948

Ok so here's my first full charging cycle results

Now here's another shot with 4G only and exact same set up and apps as before. Aod on all the time. I turned airplane mode on @2am then off @8am

Always preferred the Exynos and this guy has the qualifications to know what he's talking about. If anything it looks like they may under-clock the Exynos to the Snapdragon can keep up

They did under lock it but I think it's because of the battery/power consumption. When the device was tested on geekbench before the launch, lowest frequency was clocked at 1.9 and highest at 2.9 they lowered them by 200mhz each but it reached 9250 on those values. I think we will unlock them when custom kernels show up

Having various mixed results..
Still better then the SD version, not sure why the OP said it will be the opposite this year.

Again look at other benchmarks ie gfxbench, webxprt speedometer etc

Well, theres a known scheduler bug, which maybe/not will be fixed with the upcoming March update. This should fix these problems.

@AndreiLux is looking at it maybe he will find something or maybe he won't we'll see. I didn't get the march update yet.

I'm not sure if maybe I'm misunderstanding something or not --- but aI thought all the talk was about what a giant step forward the Exynos device new processor was supposed to be -- thus making the Exynos far out perform the Snap this year ??

It is twice as fast as in single core performance and 10-20% faster than the sd845 in CPU but GPU is underwhelming maybe it will be fixed by a software

I have the March Security Patch Update.
Seems it's still not fixed
Guess it's a governor bug or the Exynos is borked.
