Is the phone temperature really that high? - Xperia Z Q&A, Help & Troubleshooting

Hello, I've been reading about this phone and i noticed that everyone is talking about this phone heating even after just browsing web and that CPU temperature is higher than on other smartphones.
One user said that he has the CPU temperature of about 65 C when browsing web and that it is usually like that.
In my country it is 40 C in the summer and it is very very hot. Do you think that that will be a problem if I get the device?
What are your cpu and battery temperatures?

There are plenty of people from (Spain, middle east, other warm countries) who have the phone and they don't have any trouble.
I also had a heating issue, but it seems to have gotten better and better, now I can play games without the phone heating up a lot.

All phones get hot under stress, my o2x gets quite hot If I play a 3d gfx game. The HTC one gets even hotter.

It gets hot. Just like any other smartphone. Not quite as hot as my previous Galaxy S II in normal usage. Benchmark the XZ with Antutu. Voila, you can fry an egg of the back.

I don't play 3d games on phones and I don't mind if it is hotter on hand than the currently used S2.
I just want to know is there a possibility that cpu it will overheat and die or something like that.

No the cpu wont die.the phone has a built-in app that monitor the cup temp to prevent over heating and the phone will shutdown when needed.

Got XZ in my hand right now, I tried the HTC one in the shop when I was testing both devices before deciding with one to buy, the htc one got hotter doing exactly the same things.

Hmmm.... Okay! That why your signature is always sent from p990?
Never the less the XZ is a great phone, I just cant deal with dead pixels, they make me ill (99% won't even notice dead pixels with PPI as high as the display on the Z, I just have sharp eyes). Definitely gonna give Sony another go in the future. Will be sad to see my XZ go back next friday.
Its one of the most beautiful phones I've seen. The temp isn't that bad and since .434 update its alot less toasty, just gets warm (not scoulding) and as has been said, if the cpu does get too hot, the phone will shut down (That wont ever happen though).

You can check with Bat Stat. It's a widget and work very well.
From my experience a mobile completely in idle should stay at 25/30°C, messaging and do some other light things up to 35°C and gaming 45°

Temperature change means that your CPU is working. That's why you use more battery. If you want to preserve your battery on a rooted phone you can use apps like "SetCPU" and set as max cpu speed 1016 MHz. This will not reduce drastically you phone speed but will help you to preserve more battery. When you want to play some game set the max value back to 1500 Mhz

Atm I was reading a book from Play Books and temp is 29. With my Note I had similar values.
The thing that is different between XZ and Note it's that XZ can't exchange hot cause it's waterproof and Note can do more effectively.
XZ has a front and back "glass" so it's more sensible about external temp.
Here in Italy summer it's coming and I'll expect about 30° CPU temp as normal

CPU???? xD I was talking about batt temp, around the camera gets very hot sometimes... how can I see cpu temp?
but like i said my battery is draining fast, I used to be able to get like above 24hrs on 1charge
and now I'm on 3% in 9hrs... it bothers me...

My fault, i was talking about battery temp. Cpu temp can't be monitored, but i think that is directly propotional with battery temp
Yeah is normal it is a special feature Sony build in. That's foe the winter time to keep Ur hands warm when u use the phone. To bad they do not included a turn off switch for it.

Today I wanted to test how is the battery of this phone. I had unplugged from charger at 6.30 AM and connected to PC for 10 mins during the day. Now I have 33% remain and I went on YouTube, listened songs with Spotify (offline), SMS, FB, Twitter, Viber, Play Book: a normal daily use for me.
I have .253 fw and Doom Kernel with wheatley governor and cfq scheduler. 1026 MHz max - 192 MHz min. Juice Defender Ultimate for mobile data and WiFi always active when I am at home or at work.
About 18h without charge. For me it's an exceptional battery life. (when i hade Note I used to go with 3 more battery in the bag!)

[Q] Overheating, throttling, gaming performance

Since one month I am considering an upgrade of my good old SE Neo V. I mainly use it for gaming. After a deep research, and a lot of read I have narrowed my pick to 2 phones Xperia SP and Nexus 4. Both devices have Adreno 320 and similar price level which is vital for me. Since the overheating, throttling, gaming performance on N4 is quite well described over the web the problem seems to be the lack of similar information over XSP. I would like to kindly ask you for help with running few stress tests (you can use app StabilityTest (ROOT optional) by intostudios) and posting those results here. Also if you have some expirience with gaming on you XSP please feel free to write something about it: is there any problem with 1GB of RAM while gaming, or with touch after the device is heavily used for 30-60 min (I know about the issue when XSP is on a flat surface), are all games available for XSP?
All this data should let me make the best choice about my future phone. Thanks in advance to everyone willing to post your results below :good:
No problems while gaming. Playing iron man 3 while charging heats it up. No running out of ram issues.

Would it be possible for you to do a Stability Test to see how much CPU clock is decreassing during full load?

Stress test will only end when your phone crashes. It is used to test for stability after overclocking etc.
If it doesn't crash after 30 mins then you can end it.

Seriously what's the problem? Nobody is going to keep testing the phone for you.
If 5 hours is not enough I don't know what is.
I just wanted to see how much juice the cores loose after heating up. It is an important data for me thats why I am asking for it here in xda.
@jasonwsc it's not just for me maybe someoneelse would like to know this data

IPhone constantly telling me "overheating" even though it's not

Ok so having this issue with my phone...for some reason the past few days it constantly giving me an overheating warning...now the hottest my phone had reached was about 115°f under heavy stress...but it's giving me the warning even when the phone temp is in the 70s or 80s f....thought it was Rom related...factory reset a few times and have tried a few rims out...the only thing that has changed is I went from an otterbox commuter to and Uag case...but I just don't understand why it would give me warnings when the phones not even hot

Have you used an app to monitor the temperature? If you have done a factory reset and have went back to all stock, it might be a defect.

Check your GSAM alarms. Menu > preferences > alarms > temp higher than... I set it to 48 C. That's about the borderline for me.

[Q] Which one's better? Note 1 or Grand?

Hi, I searched the internet to find that there are two phones I can buy which are in my range: Galaxy grand and galaxy note. I have to choose one of them. Please tell me which one I should buy and why.. some points like larger screen, s pen, 1.4 GHz processor are making me want to buy the note. The websites on first page of google also tell that note is better, but I want to know what you guys think?
I will buy used phone, as prices of new ones are almost double.
What is the average battery life of these mobiles? Not the standby time which they say on the features list, but the average usage time as experienced by the users. Are there any hardware related problems which many users generally face? Should the fact that note is one year older bother me?
If anyone is reading from Pakistan, I would love to take a look if you suggest me another phone with second-hand price around 23,000 to 29,000 PKR, having more than 4.3 inch screen, at least 8 mp camera, jelly bean and at least 1.2 GHz processor?
I currently have HTC sensation so I don't want to switch to an HTC device.
Thanks.
Note 1 is way better
Note has better gpu than grand
Grand has poor diaplay compared to note..
Spen is unique abt note..
Camera too also is better of note..
I compared both devices in real lifre I feel note better
So I bought note = better..
Both devices will get 4.2.2 as last update (thogh not officially confirmed)
Battery back of note is good..
Its good in playing games..
Note has way better development than grand..
All roms exists for note..

Thanks, what's the battery life in hours? Sensation's life is around 6 hours with normal use and games and heavy browsers drain whole battery in maximum one hour. I will be highly inclined towards one phone if it has much more battery life in comparison.

Post Your CPU Temps!

Tegra 3 is one of the hottest processors out, we all have experienced it heating up and the notorious heat lag, however how hot in Degrees C has your cpu got?

What are you people using to monitor the CPU temps? Could you also post which kernel and rom you are using, and if over/underclocked? I'm very interested in these.
