Thinking of RMAing my device - Xperia Z2 Q&A, Help & Troubleshooting

Whats up XDA,
Like a lot of people here I'm having constant overheating issues. But, unlike others it's not just related to the camera. my device is noticeably warm to the touch when: listening to Google music, Surfing on Chrome. or any activity where the screen has to be on for 2-3 minutes. It idles at aprox. 93 degrees Fahrenheit all day.
My question is, would exchanging my device for another make any difference?
From what I hear, this issue basically stems from the glass case and the CPU. I really love this phone, and I dread switching to a corny S5 but if all these devices are like this I think I need to switch. Overheating always leads to a short life for electronics.
Thoughts?

They are not all like this. My phone only gets really warm during 4k or if I'm doing a large download over LTE, while doing a titaniuim backup, and gaming at the same time LOL. My phone rarely warms up.

Don't know. What app are you using to check so we can make sure we do an accurate comparison?

Can't say my phone gets hot. It gets warm but nothing major. I've been using mime for about 10 mins just surfing and reading Tapatalk and I'm idling at 45-49deg C.

Have you eliminated background process from being the cause of your high temps? My Z2 only gets warm when playing games, streaming HD video, etc.

Hmm in a 72 degree room, you're worried about 93 degrees at idle? That's 33 degrees Celsius, which is not very high at all.
Unless you're having high CPU usage, there's nothing wrong with your device.
If the device gets warm to the touch faster than others notice, but otherwise acts the same, that's probably a GOOD thing. It means the phone is moving heat away from the SoC more quickly and not acting as an insulator.

Min never get hot only warm on 4k video for 7. 23 min and I am still on 402 room manufacturer 14w20

They using a G3 for 5min then you'll find out what running hot is. The Z2 runs fine temperature wise.

You did not mention what app you used to measure this ?
And i take it you are referring to battery temps here.
Also mention what the ambient temperature is where you live.

Don't want to make a new thread for RMAing so sorry for hijacking this thread OP. My digitiser has been acting crazy recently, specifically as close to the right bezel as possible and nowhere else. The phone has not been subject to water or anything of that sort. Has a screen protector on it and a plastic clear case and has never been dropped. Glove mode is off so it isn't that either. Does anyone here think Sony would fix it under warranty? Locked bootloader/rooted with DRM keys intact so I can always revert to factory too thanks in advance for any replies!

[Q] SGS2 getting very hot

I just received my SGS2 this afternoon and I've noticed it getting uncomfortably hot.
All I've done is root the phone, install a few apps and just general exploring/messing around.
The screen is getting very hot, the top half especially.
So is the back of the phone, again the top half mostly and especially the part just to the right of the camera lens.
Any hotter than this and I would be seriously concerned...
Anyone else?
No. Ten characters
HI there
I have the galaxy S2 for few days. Today this afternoon, I also experience the same thing. It get so hot (i can really feel it) and the battery is drained to around 20 % in just about 40 mins. The phone is charge twice.
During the hot time i did
- The battery was around 80%.
- Wifi is on
- facebook app is on.
- the phone was in a sleeve all time and i have not use it at all.
the phone become really got until i restart and close all apps.
I look at the battery usage... the graph was on peak for few hrs (not sure how)
media usage is 28% the rest are below 20%
anyone share words of wisdom? defected phone?
Mine has been pretty cool for the most part. It started to toast my fingers around the back where the camera lens is after dicking around on Angry Birds for 15 minutes but aside from that, no problems with heat.

battery drain faster (alot)?
can you guys post temperature numbers? can pull those from dmesg log, or OS monitor, or system panel, etc.
anything higher than 40C is not the best.

Or more likely, defective facebook lol.
Either way, the hardware has built in overheating protection as it will shut down automatically. Heat is generally no problem - electronics is used to being toasty. My 3Gs can get hot as hell after a surfing session or movie watching, still going strong (or warm), haha.

After being on standby for over an hour, OS Monitor reports (under the battery section, no other section reports temperature) that the phone was 36C, after a few mins of playing this jumped up to 41C then back to a stable 39C.
If the phone (do we still call these things phones?!) gets overly hot again, I will check the temperature and report it here...
Edit: Now that I've taken it off charge, its gone down to 25C
I would check your wifi network. That sounds like a typical scenario when the phone starts to lose wifi and kicks into 3G and back and forth repeatedly. It's trying to get and keep a connection.
I don't have my SGSII yet, but I do have a blind spot in my wifi network that ironically is also the area of the worst 3G coverage in the house. Every phone I've owned will do something similar on occasion.
I also have this issue.
I was playing Angry Birds for about 20 mins and the phone was getting so hot.
Is this safe or should I be concerned?

Battery drain+Heat=Wifi+Stock Browser, please read

Hello again dear xda members
I've been using S II for over 2 weeks now! I get the following(which many of you do get also). When I turn on WiFi and start surfing, the phone starts to overheat and battery is drained like a juice.
Well, after a long study, I've found out that it's the stock browser's fault!
Yeah! I opened WiFi, surfed a little and it started to heat up! Well, I was trying to download something, and since stock sucks at downloading( except if you add to it an app from the market called Downloadfiles) I opened DolphinHD!!
What I saw, or felt-whatever-, was just
After 5 minutes, the phone cooled down, temperature became normal and of course battery was less consumed!
So, to all people who have heat issues, it turns out(at least in my humble opinion) that it's the stock browser's fault!!!
Any thoughts anyone? Similar experiences?
I've been using it for 10 days and experienced no such overheating, but battery time should be much better.

Really? It doesn't overheat never? even not when playing games?
I thought mine was faulty, but I went to couple of stores where they have it open for customers to play with, and I did the same as mine and it started to heat up!
Mine heats up a bit after playing a game or running a certain app for a while, but I never experience overheating with the stock browser. Though you should take in to consideration that the GS2 is a thin device, the CPU is close to your hands. Most phones also have to exessivly keep searching for connections because it is weak or something is blocking its way. The transmitting/receiving device is located at the top along with the CPU so it'll tend to get hot. Most smartphones do overall.
Also, the phone gets hotter while using it connected to a charger just because the battery is filling up the same time you are using it. Also, take in to consideration that no patch for true dualcore support has yet been released nor announced. Just some factors why the phone heats up.
thanks man!
Well, heating up is normal-as far as I read in here-... But when using Stock Browser, I'm talking about overheat! really! I believe it's a bug, since as said, nor Firefox, Dolphin and Skyfire(I use all of them) produce that issue! And I disabled flash content(thought that might make it better) but it was the same! Don't know!
Anyways, thanks for answering!
OVer wifi I have no problems. Over 3G is another story! and playing games is another story. It warms up every 5 minutes while playing games.
Yours too huh? well, mine does that on WiFi!
What is Overheating? How do you know it is overheating unless you know the temperature of the battery? Well OP and other posters who are saying the phone gets overheated please mention the temperature of it. The ambient temp of Europe/USA is 20-25°C Max, and if the device runs even cool then it will have temp around 30-32°C, that is much higher than the ambient temp and probably that's why you guys are feeling the phone is overheating but in fact it's not. Here in Calcutta, ambient is 32-33°C and the Phone temp in normal is the same, so we/I don't feel it's overheating, only when I surf net for an hour straight with charging then the temp rises up to 44-45°C, that's when it could be said that the phone is running on high temp, still for the hardware we are given 45°C is not hot.
So before saying the phone is overheating please check the battery temp.
Regards.
how do I measure battery temperature?
Ok, Battery life widget?
I'll measure then I'll let you know!
There is a reason stock browser uses more battery and heats more. It uses GPU to render pages more quickly! But for me even on stock it is not that hot, more than on other phones, but thats what you get for a thin phone.
Maybe somone will test battery life with stock+GPU and dolphin browser with no GPU. Maybe the difference is not that big at all, maybe just GPU heats more than CPU but uses same battery.
now let's not forget android doesn't have graphics acceleration, and without it the GPU has to work harder which generates more heat

Your ambient is 27°C, right? So it's normal to me. Anything less than 50°C should be OK, imo.

Summer in Greece and sub-30-degrees Celsius don't go together.That's why we're hot!
Anyway,****ty joking aside,inside a bus today,under the sun with an ambient temperature of about 35-36 degrees(dunno how you put the degrees symbol pal ) and with my GPU overclocked at 400MHz with 1100mV using tegrak overclock ultimate,I played some Angry Birds and,although the phone reported no more than 44 degrees,it was very hot at the top.
My opinion?If you(or me obviously) manage to somehow burn/fry something,make sure to do it so bad that it doesn't even respond to Chuck Norris' roundhouse kick! That way maybe Sammy won't notice...Shush!

Funny comment anyway.

Phone seems to be overheating.

My phone gets really hot when using the data connection on the phone. When i surf the web, video chat, or do anything that uses the data connection the phone becomes hot. it also happens when i play games too. it gets hot around the lower part of the phone around the area where the home buttons located. Just wondering if this is happening to anyone else before i get it exchanged. The highest temp i got was 104 Degrees F.
i cant say for sure what temps are safe. i haven't done the research. but my wife and i both will notice the bottom getting pretty hot when pushing the phone. surfing & gaming. not so hot you cant touch it, but much warmer than any of my other droids iv used in the past.

i just played dead trigger for 10-15 minutes and now the phone is at 95 degrees lol. Idk if thats normal.
My phone gets hot at the bottom, as well.
Hopefully Samsung will make some firmware changes to better regulate clock speed according to temperature.
My phone gets really hot also towards the bottom when just using it for anything. Then again it doesn't help I'm in +100 degree weather and outside all day and night.

Yeah, just like in desktop computers, ambient temperature plays a big part.
Mine gets very hot as well. I'm on the 2nd one too. Its just because it is a very slim design, coupled with a strong processor = hot.
Gets a bit scary when playing a game for 20 minutes though..

You can change the clock speeds with SetCPU, because they're set pretty high on stock, 1.5 Ghz max and 1 Ghz min.

[Q] Z3TC overheating *Help*

Hi guys
I just bought my Z3TC this week. Overall I'm super happy to have it. However, I notice each time, after playing around with it for 15 ~20 minutes (Surfing, photo taking, gaming), the tablet gets really hot near the home button area.
I installed a temperature app and found that the CPU was at 66'C consistently and the Battery was at 45'C. It was hot to the touch, not to the point where I can't use the tablet, but when my palm rests near the home button area, the heat is noticeable. It's not just warm. The app (CPU temperature) didn't show any throttling of the CPU either.
I'm worried that the heat will cause damage to the tablet's battery and CPU lifespan.
Does anyone else have similar issues?
THanks
What games are you playing ? I haven't noticed any elevated temperatures in my device but then again I don't typically game.

It was MMX racing.. just a simple 3d based game.
But I notice, the heat generated isn't just from gaming. It seems it's happening when I'm using any apps. Is it possible to throttle the CPU? Or do I have a defective version?

From my understanding CPU throttling it controlled by the kernel and would therefore require root access.
Out of interest I downloaded and played dead trigger 2 after reading your post. My device certainly got warmer but it wasn't hot to touch. With the polymer backing I would be concerned of warping if you have excessive over heating, similar to the issues with the Galaxy Tab S.
If I can get some time I will monitor my temps over the next day or two and see what happens.

I've never heard anyone say the tablet heats up. I, myself, play games on the Z3 tablet compact, 3D / 2D / whatever D, sometimes even while downloading, the thing doesn't even know how to heat up, it's always like "nope bro, no heating up from me, u want heating up? Go get something with the Tegra K1 inside". Jokes aside, the thing seriously never heats up. Possibly a defective unit? I suppose you could ask the service center to take a look.

Benchmarks

Hi guys, this is something that keeps me up at night. The recent software update was supposed to make performance of the Moto Z better, and in actual daily usage I find nothing to complain about, but when it comes to benchmarks it's a whole different story, I have the uk version by the way. To be frank, I used to get about 129 000 in antutu, which is pretty low to start with, and now it's down to 126 000, geekbench is lower than you would expect from this phone too, at about 1350 single core and 3810 multicore. So basically I started this thread as a place where we could share our benchmark results and discuss them, because I have a feeling I just got an unlucky unit, because it also gets real hot real fast (up to 60 degrees celcium), and I can't make it last for more that 4 hours of screen on time, and I'm really not a heavy user. I just feel strange about this phone, because I love everything else about it, and it’s good that I do, because resale value on these things is beyond awful, tried to sell it for 500 bucks for months with no success.
Benchmarks mean abso-farking-lutly nothing. If they are keeping you up any night, you have a mental issue. I suggest you see a shrink.

Well, there is no reason to be so toxic my friend, my main concern is that I may be the only one here with such a low score, and since the score got even lower after some time that could mean I may have a defective device, and that would be a real problem to keep me up at night.
I don't think there's a problem with your unit, 4 hours screen on time sounds normal without the battery mod on. That drop in benchmark score isn't very significant unless it continues to drop dramatically. I have the UK model too, and it is underclocked by default to 1.8GHz. You could try the Turbo Z kernel to improve it
Also mine gets really hot fast when using Daydream VR or anything intensive but 60 °C isn't dangerous for the SD820. (You could check battery use in settings incase something is keeping your phone awake.)
Geekbench 4:
Single core 1369
Multi core 3779
Seems benchmarks are pretty similar. I'm on rooted Android N but stock kernel so same as yours.

Thank you for your comforting and friendly reply, in battery settings Android OS, Android system, and phone idle are on top when I'm not using the phone actively, I've had laughable results sometimes, like yesterday I had 30 percent battery left with only about an hour of screen on time, again no gaming involved, but this usually happens when I'm moving around, if I stay at home and nothing happens to the phone it usually won't drain battery like that. I think the reason the phone gets hot easily is obviously because of how thin it is, for example, when I keep it in the pocket it's just as hot as my body tempreture, since it just absorbs heat that easily, but has a hard time getting rid of it.

You're welcome. If you click on the graph you can see the awake time too, lately something has been keeping mine awake and draining the battery too. Not sure what it is yet, but if yours is getting really bad screen on time it could be similar. Likely an app running in the background keeping the phone awake which would heat it up more and drain the battery. There are wake lock detection apps that claim to be able to tell you which is causing this.
As you can see it's awake for long periods of time when the screen is off, and it really shouldn't be. Hope this helps :good:
