Hey guys,
My Optimus V runs much coolest than any of my previous phones, and this worries me a bit, mainly overnight when I sleep and my A/C is on. I've woken up and seen my battery idling at 9 degrees Celsius. Now its not really THAT (no way!) cold in my room, but it seems to be more prone to the cool air than anything else I have.
So I wonder, what are the safe ranges for the low end? Today I woke up with it at 10 Celsius so lets use that as a benchmark. Should I try to keep the phone warmer? Note that typically out and about I hover around 30 Celsius without too much phone usage.
Thanks for any input.
Normally you should keep your battery warmer than -20 C and cooler than 50 C, so that means you are inside the safe working limits.

Thanks for the reply. Is there any documentation to this, if available, or is this just the commonly accepted belief?
The -20 and 50 degrees celsius are the temperature limits written on every battery-powered electronic device's manual.
Thanks again. I'll check it out.
read your phone manual dummy.

sometimes on certain ROMS when you over clock the temperature gets pretty high (like 101 degrees) what is an unsafe temperature to have it at?
I think some people have said that a good cut off limit was 48˚C
Don't remember exactly though.
I would say that if you hit 50 C you should turn your phone off and take out the battery and put it in the freezer so as to avoid melting stuff
I've seen mine go as high as 55 C while simultaneously streaming music and running a wardrive app (w/ Google maps being pulled continuously) on a 3-hour drive - no OC'ing
I'll point out that the Eris uses lead-free assembly, so the solders involved require temperatures that peak out in excess of 200 C (for short periods of time). Nobody's phone is going to melt when the battery is at 50 C. Moreover, knowing the battery temperature doesn't really tell you what the temperature of the app processor or RF PA are - probably they are higher, but who knows, really?
Having said that, it is also true that there isn't any "cliff" that the device falls off - all the processes which eventually cause reliability problems are thermally activated, so higher temperatures, and a lot of time spent at high temperatures, will increase the probability of device failure (or rapid wear-out of the battery).
And having said that, I'll also point out that this thread has nothing to do with development.
Mods, please move it.

Dont do this....I dont know what exactly a lithium ion battery is composed of but going from 50 C to less than 0 C causes serious problems with electronics.
On a lighter note i have had my battery to 54C and my phone is still kicking like the day i got it.

I run mine all day at 806, very stable. I have the temp warning set at 40 C and only hit it once so far, and I was streaming music, bt, wifi and charging for like 2 hours. But mine, knock on wood doesnt heat up. But to answer the OP's, I have mine set at 40 and only hit it once. I like to be better safe than sorry.
thanks for your help! i am kinda paranoid about my battery exploding or something lol but now i can stop worrying. also this does have to do with development because OCing is part of developing.

I got a replacement last week and was able to root just fine.
i always say that when my battery is too hot..like oddly too hot to the touch, its time to turn it off and see whats making it happen.
i actually had that issue with one of the earlier roms and i wound up switching somethings out within the kitchen and it went back to normal

off topic, but from what i understand replacement eris is shipping with 1.5 and then you get the OTA. but the OTA doesn't change the bootloader so you are still able to root.

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.

My ambient is 34 to 30 °C
Ok, so my phone is fine? Wow! !! thanks
that really made me happy!

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!

^ What he said!
Even tho Skimminstones' reply was funny as hell ....
49 *is* pretty damn hot. Anything over 40 and I start to worry a bit, which does happen occasionally with some kernel betas, especially early on after that initial flash/till you do a couple of charge/discharge/reboot cycles. Running a kernel script before you flash the kernel tends to make this less of a problem I've found.
I'm running an early (stable) version of Siyah and I find the average temp of the device with light/no use is 23-25, moderate use is 25-27, 27-31 with heavy use (all dependant on ambient temp), and it sometimes gets up to 36-37 when charging, more so when the battery has less charge (say less than 40% or so). The temperature gradually drops as the battery charges & returns to "normal".
Without knowing what your setup is (i.e kernel, rom, etc), its hard to say what might be causing this.
But as far as I'm concerned, 49 is *not* normal.

You mean the sexy body or the temperature
For the temperature, it is quite high for me also. Especially around the camera cover, All of people I know have this high heat also.
Never measure by numbers..So I don't know about that
Phone used to get hot on stock roms but thats it
Mine runs very cool with my Anker battery. Never gets hot.
in short i forgot my s3 in the car and it was damn hot...i came back to find it over heating and in boot loop.after it cooled down it was back to normal except now i have heat problem when i use the net or play a game...the question is was its exposure to over heat the cause of ruining something?

It definitely will get hot, I remember watching my son at swimming lessons last week.
I am in Bangkok and was outside using the phone extensively on 3G data, ambient temp 35+ Celsius. Can't remember exactly how hot the battery got, but sure out read well into the 40s.
Didn't have any hardware or software issues though.
As far as exchange goes, you could try, but they may reject the claim as you most likely were operating the device outside it's design limits.
From the Pg 172 of the GT-I9300 User Manual: http://downloadcenter.samsung.com/content/UM/201206/20120613110217963/GT-I9300_UM_EU_Icecream_Eng_Rev.1.0_120607_Screen.pdf
Do not store your device in very hot or very cold areas. Use your
device at temperatures from -20 °C to 50 °C
• Your device can explode if left inside a closed vehicle, as the internal
temperature can reach up to 80 °C.
• Do not expose your device to direct sunlight for extended periods of time
(on the dashboard of a car, for example).
• Store the battery at temperatures from 0 °C to 40 °C.

All hardware is not exactly the same, so your device may be less torelant to excessive heat than others or vice versa.

Overheating will cause bootloops. I used to use my phone at work as a wife hotspot because it was faster than our work net. I plugged it in and it would always die after two hours from overheating. Finally rigged up a way to keep it in the freezer lol

Based on what you said, all seems back to normal.
To summarise;
It WILL heat up, depending on environmental conditions and also your using habits. CPU and GPU intensive apps and time spent on this state, and also general use whilst charging etc will heat it up.

+1 to the "It's fine"
Pull out the battery, there it'll list a safe operating temperature. The battery in my phone is "Safe" up to 60c, but it probably shuts itself off at around 55ish. 45 is nothing to a phone, so don't worry.
You're probably just being paranoid, paying super close attention to any kind of "Warm" after the overheating incident. It was probably reaching those same temps prior to leaving it in the car.
Hell, I left my Evo 3D (Super famous for overheating) on my black leather seats, in the summer, plugged in, and GPS running, for an hour or so. It shut itself off and wouldn't turn on for 45ish mins while I let it cool down... And it's running just fine now. Lol
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?

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.

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!
