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

Ok, I get 41 to 45 °C degrees!
So, no overheat just heat!
So, based on what you're saying, this is normal?

Your ambient is 27°C, right? So it's normal to me. Anything less than 50°C should be OK, imo.
Regards.
My ambient is 34 to 30 °C
Ok, so my phone is fine? Wow! !! thanks
that really made me happy!
I thought it was faulty
Thanks so much everyone for answering

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.
hi,
i have SE x10i and i downloaded some apps in the market and my phone suddenly restarts... and i flash it on SE PC companion and its now ok
the problem is that when ever i charge the phone the battery heats up and then my phone also heats up and shuts down... i get the battery out for some few minutes to cool down and then it gets ok.. but because i want to charge the battery but still same problem..
what should i do??
regards,

Are you heavily using the phone (gaming, watching videos, streaming, surfing the net) while charging?
Install setcpu and use a temperature trigger of 50C (or what you want) to limit the cpu.
Mine is set for 768Mhz.
And if you are using it while its charging try not to cup the back of the phone, you trap the heat.
If it keeps shutdown when you charge, you should bring it to SE service. Maybe this is hardware problems.

i already did that sir..
i also update the rom to GB but still the problem is the same..
when the cp heats up its restart automatically..
@all
where can i DL such apps that can normalize the cpu's temperature..
i cant charge normally because as what i have said
it heats up and shutsdown thee phone..
Aw man that sucks, keep in mind your battery life will get worse if its heated too much.
Sent from my X10 using XDA App
yeah really really sucks.. i cant normally charge with my charger
coz when the temperature rises it will stop charging ang the phone restarts or automatically off...
thats why i need your opinions! please..
i dont think this is a hardware problem because
this is brand new... and i dont use it agressively...

Not all brand new devices are in perfect shape. There's always a factory defective one..
Try consulting your problem at any service center of S.E. or ask for a replacement. As you said its a brand new device it has warranty.

Hi Nucleus55,
Although i'm relatively new to xda, i'm also relatively "old" to h/w related problems, so here's is one piece of advise if you like.
As stated also from other member's previously "-- X10B --", if the phone's temp rises to a degree where it auto-reboots and stops charging, and if this occurs every single time, then you should probably replace it from your nearest SE shop. Especially if it is new and under warranty. As stated from "-- X10B --" there is always the possibility of a h/w error or in construction and/or design flaw in that specific model. You never know.
Personally, i got this "batterylife" widget (from market) which shows battery status and temp, and for me, when i charge my phone, it has never gone above 40 degrees Celsius while idle (charging only) and up to (MAX) 48 while under heavy stress during charging, like games, videos, etc.
I have never seen it gone to 50 degrees.
You could also do as previously stated by "kindred7", that is, install an application and set the max degree to 50 degrees, although i strongly recommend (this is always my personal opinion), when it comes to ALL electronics, to always keep them as cool as possible. If this is not possible, because you tend to stress it all the time either from games or videos, then you could find a better cooling solution, like maybe removing its cover while charging.
I have just tried it myself about a half an hour ago to see if there is any change in temp, and i have noticed that in my work space where the ambient temp is around 25 degrees, the phone while charging and uncovered, was stable at 38 degrees Celsius.
Also, if you a lot of functions ON like Wi-Fi, GPS, Bluetooth, then it is obvious that the phone temp will rise to its max. If so, then try to disable any things you don't need, not only while charging but always.
That's all that i can think of right now
this has happened to me after i updated my x10i to 2.3.3 .. the battery life has just got worse and sometimes while heavy use the battery temp rises very much.
Any Solution will be helpful.

From the symptoms you've listed I'm pretty sure you need a new battery due to the heat exposure.
When you are charging your phone make sure you have your screen off. I know this sounds stupid but I found it stopped my phone from overheating while charging
my battery is heating aswell
i upgraded and did not use my phone for 5 hrs ish and it was just on my table and then i smell smoke frome my phone and it was like my battery was a bbq

yes i think this is the problem that i forgot.
i expose it to sunlight while we are drinking some beer with friends outside of our house . and
because i have some sms i grab my phone and damn it was so hot.
so i put my phone inside the house and after that it started to resart whenever the temp rises, or even i use a short period of time...

even when i shut down my phone and try to charge
when my phone starts to heat up
and suddenly it stops from charging
and the phone is very hot as well as the battery
ill try to replace battery, if still the same
maybe i will forcely go to the store that i bought my phone.
I have the same problem
maybe SE company should read all the negative feedbacks on there Phones...

Hello!
I have some concerns about the heat of my phone. I've read some threads, but everybody has different opinions and readings.
Basically, with room temperature at around 27-28, during browsing (especially with lots of scrolling through images) the phone will heat up to 40-41C (even to 42 with some encouraging) within 5 minutes, so the bottom front and back are very hot.
During other use, like writing a few messages in Whatsapp, going though settings in programs, menus etc it will, slowly, but will go up to ~36-37C.
Is it normal, or should I prepare for war with the shop I bought it from?
are you rinning a custom rom/kernel or stock? if so which?
I've found that different roms heat up more than others.
I'm using anaraxia rom 10.3 build and have no heat problems and the battery life is amazing!

Using a stock rom. I'm not experienced enough to flash custom roms yet, and I would also prefer to not void the warranty, at least since I'm not yet certain that my phone is not damaged in some way
I'm not that bothered by the heat, my only concern is whether this behavior is normal or not, and whether I should start the whole warranty war sooner.
Well I wouldn't be bothered tbh.. I've had 42°c while heavy usage and charging. If your phone overheats and burns out send it in then.. No point doing it now unless your warranty is out soon?

41.5, but how much did you strain the device? Today in a room where the temp was +-30-31C, while browsing XDA (which seemed to strain the device a bit) I got up to 44...
Also checked the idle tempretures, it's usually the same as the room temp at the moment, so it's not that it's always hot, just when used.
R: [Q] Regarding heat
Its weird that it should heat up while doing normal stuff...im on international version and last time it heated up was while i was playing modern combat 4 online after 2 hourse while connected to charger....so maybe youve got prpblems if it heats up like that only by viewing messages. I watch videos and browse the internet everyday, it never heats up. Im using stock rom and syiah ketnel...
Sent from my GT-I9300 using xda app-developers app
While doing regular stuff like messages etc it doesn't heat up much. The first test was done while browsing, but I kept it at 40% load and 1400mhz, so it can't not heat up. I think that room temperature matters, I live in a hot area, today was 31C.

I've had that "problem" (well it's not really a problem, only a minor annoyance during warm seasons) with stock rom too.
Didn't have that much experience with other roms and kernels (I'm very picky with features) but I never noticed it on Siyah with Wanamlite.
Stock kernel is far too happy to ramp up clock speeds to slightly improve response time (or so is the theory... practice is not noticeable) so it will heat up your device. More heat of course also means higher battery drain .
Note that a protection around your device usually keeps you from noticing this fact (while the phone gets even warmer due to worse cooling)

I've also noticed this heat problem, I'm also on a stock rom.
Using the "CPU power saving" in the Power Saving setting has helped, so I figured it was the kernel ramping itself up.
It's not that noticeable to run at a lower cpu frequency except that some games are sometimes choppy now
The fact that stock rom likes to ramp up the clock speeds is correct. Just by simply fast scrolling back and forth through pages on forums etc makes it go up to 1400mhz and keep it at 40% load, that's why I get the higher temps.
I tried almost all ICS and JB roms for Xperia X10 but I had the same problem ever,that is device reboot when the battery's temperature exceeds more or less 38°C,after reboot I can't use my X10 until the temperature decreases to 30 °C because if I try to unlock the phone and I try to do something,after 1-2 minutes the phone reboots again...
usually,in my case,the temperature increases faster with mobile data turned on or gps turned on
Now,I opened this thread to know if I'm the only one with this problem or you too and if someone of you was able to solve it (or if you've just never had the problem) you can post suggestions,in this way:
ROM: name of the rom and version
Kernel: name of the kernel and version
min CPU frequency:
max CPU frequency:
various performace settings: (dithering,ram compression,etc)
original SE Xperia X10 battery: (yes or no)
age of battery:
You can see battery's temperature downloading TEMP + CPU v2 from google play store,it's a widget
I know you are not the only one person with this problem, as I already got same questions from two more persons. I don't know:
1. why temperature is much higher on JB than GB
2. why it's causing some problems on your devices, I have 39°C most time and my device running full stable up to 1152 always, sometime can loop on 1190.
Maybe try to decrase frequency?

my max cpu fraquency was always 998Mhz and min frequency 245Mhz...
Then there is a problem. I think there could be some problem with Kernel itself, like too much or too less voltages for each frequency, Did you try SetXperia or did you manually change it before?
Buddy,buy a new battery...it's very cheap on eBay...I bought one for something like 4 euro...and it's Sony original and solved overheating problem!! X10 uses a lipo battery...when it start overheating,it's time to buy a new one...I'm 99% sure software has anything to do with this problem!! The fact that your phone reboot it's probably caused by a peak of current the phone ask to your battery and this one is not able to handle...so it's voltage fall down below the minimum value(called Lipo cut off) and the phone turn off!! My suggestion is to buy a new battery...good luck!!

We are waiting for your future reply .
I'm testing the new battery,now I have a new problem,the temperature of this new battery is -30°C and it not charging :crying:,why??? is there something to do for initialize a new battery?
Ummm I think nope, but I see that device is not like you . First too high temp - then too less but not charging. I don't have idea what to do, maybe try to turn it off, pull down battery, put on and charge offline?

You're really unlucky buddy .
if there are no issues with your hardware then i think maybe it was your kernel, try to flash to another kernel and see if it solve the problem.

Here I'm again,after nearly a month I have a new battery but I have the same problem for now...
at least this battery charging ad the temperature is stable at 33°C but after a few minutes that i use the phone to play 2D games or to surf the internet,it reboots.
For now I haven't charge the battery for the first time (i did only a test to see if it was charging) and probably before giving a judgment I have to do some charges,am I right?
I don't know if charging is 100% needed, but you can do this if you're worry about that. As for existing problem, maybe it's something with motherboard .

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:
