I am a long time owner of the Galaxy S that has recently bought the S II.
Comparing to the previous model the S II heats up real bad with my usage and the battery drains incredibly fast. When running 10 min of flash video, my battery temp shoots up to over 50C and it drains over 20% of my battery. This is even with the May 11 ROM release.
So i would like to ask other owners to post their results with a flash video as reference (i used the video on watch futurama online S2E1 as my test if you could use the same one maby). Running full screen for 10 min at lowest brightness what is your battery temp and how much battery is drained (i use Smart Battery Monitor to get those values)?
Thank you.
I think it's Flash - it will always be a power hog.
720p YouTube video doesn't even run smoothly on my Macbook Pro, so it's going to be a challenge for the SGS2.
Its not just flash. Games, market and some other stuff also causes the same thing. As i said Galaxy S didnt have such problems with runnin flash or any other content... i want to hear from other users if they are expiriencing the same problems or if my cellphone is defective.
When it is on standby it is lik 1% -2% an hour. When I just touch it and play some games or browse the web, I just see the % go by fast.
Yesterday i downloaded some games, browsed the web and played the games. 26% lost in 45 minutes.
So its not just mine.. this sounds horrible. Anyone else confirm this? Also post the 10min test result with temp and drain?
I played a game for 20 minutes, lost 20%. And that's with almost all games.
General usage - 35c
Heavy usage - 40c
Idle - 29c
Charging with no usae - 41c
Charging with usage - 44c
And when i put my case in the temp increases about 4c on average... So now when i charge it i put it near my air con. Battery is good lasts me a day

So battery does drain that fast... what is heavy usage for you?
Can you please just run 10 min of the video i did on wifi and tell me what peak temp you get exactly with it and exactly how much it drained the battery... anyone just so i can compare my results, its just 10 minutes of your time.

Really??? Videos 1080p Youtube run smoothly on my GS2, no problem at all. After updated to the newest firmware (KE7), CPU temperature is noticeable lower when playing game for me, and battery life improves too
I noticed a decrease in temperature with latest firmware too, but how much exactly is your max temp now? Give me some numbers...?
I had max 41c after 15min of game and down to 32c after 3min
Thank you. After the last update from Kies i also had a max of 42C after 15 min of watching a flash video. Before the update the same flash video made it shot up to 58C.
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!

Its not, the MAX temperature of a phone Li-ion battery seams to be 60° C
mine is constantly 25~40 (MAX)
And high levels shorten battery life until next charge
The rate of degradation of Lithium-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures

Thanks all for replying
Casings too will raise your temp, I had a cheap case I got with Koodo, and it kept all the heat in the phone, I removed it and my battery temps go down. although I keep it on when it's not charging. It's fine then.
My Galaxy Ace is always at 45 degrees......unless it was a miracle and the air-conditioner managed to cool it down

No I don't care if you're anti-Apple.
I never saw my cell going to 45'C.!!! One interesting thing i noticied is that the temp is only high between 20-70% battery charging.. After that just 2-4 minutes temp goes to 30'C!! While gaming upto 35'C.. Only charging heats up my gizmo.. Never had this problem with NOKIA 5230..
My battery once had a temperature of 50 degrees
Sometimes, it also depends on how much you're stressing the CPU. If you're doing something heavy like a lot of multi tasking or 3D gaming, it'll heat up the battery and such. Just like using your phone while charging. Happened to me a lot before so I stopped that habit.
I use SetCPU to slow down Max CPU Frequency to 480 Hz when phone temp goes >40 C. That helped.
The SII gets VERY hot (About 65) when using the Onlive app.

I use 480Mhz because more continuous CPU cycles can definitely heat up the phone. This is why any phone heats up quickly when using it and charging it simultaneously. My phone temp has never gone beyond 40C. But I would start worrying and would not use it when its charging, if it'd gone beyond 40C.
And no offense, but those who say like 60C is normal. You guys are definitely hampering your battery life.

I have a sony xperia s , and when playing graphic hungry games the phone heats up .
now i understand that the game demands resources from the Gpu and cpu ..
but is it healthy to play a lot of games on the phone ?
what will become damaged ? ( if its not healty )
Thanks a lot any help is appreciated .
Devices will sometimes heat up in normal use but excessive heat for prolonged periods of time can be damaging. Depending on how warm it gets though, you are probably fine.

Hi, I find the same problem sometimes. Heat is to be expected as there is no active cooling like for example on a desktop CPU or GPU. If you're worried about it just quit the app after playing for so long and let it cool down as I find the heat makes it hard to use the phone anyway. One suggestion that may help is switch off your WiFi and 3g when gaming. Honestly if your phone isnt over clocked I wouldn't worry as it should be able to cope with how Sony has configured it.
yeah mine isn't over clocked , i fear overclocking it .. i feel its like cooking your own cpu , logically it might damage it right ?
there's this one game called : "bombshells" the phone really heats up on it .
I didn't download it from the playstore because its not available for my device/country so i got the apk , could it be compatibility issues ? although im dead sure my device can handle it smoothly .
I used to notice significant heat from my HTC Desire and Samsung Galaxy S2 when gaming. I didn't overclock either but they both got really very hot to touch. My Samsung Galaxy S3 doesn't for some reason (even when overclocked) and my Nexus 7 does get very hot when gaming. I think there isn't anything to worry about. If you've not overclocked it surely can't affect your warranty either.
heat
heat can be a problem yes, there was an app i think that tells you the temp.
Obvious thing to do is to exit the app and shut the phone down till it cools down ,it is normal for any phone to become like that if games ,apps etc are cpu hungry etc
The first thing to break will be the battery, and that'll happen around 45 Celsius. Just stay below that and you'll be fine.
Keeping a low brightness and play without the protection case. I know that my AMOLED screen is the main cause of heat.. Heats up the battery, CPU and screen radiate heat too... phones are too small and too powerful for an optimal temperature. Brightness at minimum is a must I think.

Some games require high end devices to run smoothly and not cause any problems.. In your case, SGS3 didn't cause any since its a Quad Core device and is capable of handling high graphics games..

I have an SXS too.. But you will have to understand that our phone uses Snapdragon S3 processor which is normal to get hot since its the way it was built.. It gets hot soon and makes the phone slow.. U can google about it and read everything related to it.. And its alright to play games on your phone.. But on any Android phone, i suggest u play for around 15-30mins max when u r playing high end games with lots of graphics.. And then give a 30 min break and then continue to play.. Use kernel tuner and check your CPU and Battery temperature.. If they are above 45 degrees, let it cool down.. And i have to say, the latest .96 fw has no issue of heating.. I have played NFS MW and Asphalt 8.. Although Asphalt 8 causes some heat, other high end games never made my phone heat up.. U can try the ROM with a clean install..
devices normall heat up while running apps that use hardware acceleration.
if no app is running, the device ideally shouldnt heat
up.
Thanks for your reply. i got my Nexus 5 now,same thing about heat in games or while on HDMI - thats normal so
got xperia s too, custom rom, cpu overclocked to 1916mhz, play alot on it over longer periods of time too (2 hours) nothing bad happened to it for a year i got it so... working as intended?
Galaxy Note I717 here, heats up after around 5 songs on Cytus while playing in an air conditioned room. Prolonged use (i.e. 15 to 30 minutes non-stop) also causes it to heat up to around the same temperature. OEMs should really make it a point to put cooling systems on all their devices.
Hi, so I have this new HTC Desire X and there are a few issues that have been bothering me.
1. Phone gets warm pretty quickly while playing 3d games and (according to Caynax Dashboard Battery Widget) reaches 44C but doesn't go any higher. It doesn't turn off or do anything out of the ordinary other than being warm to the touch but feels weird.
2. With screen turned off battery life seems to be pretty good but as soon as I start playing games battery drains very fast. While playing 3d games it takes about 3,5h to go from 100% to 0%.
3. While charging the battery percentage gets stuck at 99% for quite a while. From 99% to 100% it takes nearly as long as it does to reach 99%.
Is this normal behavior or should I be worried?

Well I checked now and the phone got warm while I was simply browsing the internet using Opera Mobile (Classic). Slower than while playing games but it did reach 42C after like 10 minutes.
I found out that the music volume is too low after upgrading to JB ......

@ curiousjack-heating problem is normal thing in every device, as far as I have noticed, whenever there is heavy load on gpu, its causes heating, also while using GPS,same thing happens, as for 99% issue that's not normal bro, as already suggested try calibration, if that doesn't help, its time to pay a visit to service centre..& battery drain is normal thing, you said your lasts 3.5 hours,while mine doesn't even lasts 2hours while playing RF13,so don't worry..
@monitorstudioworker-low volume bug is solved in latest update,as of now only India has got it, I can confirm my volume is normal after latest update, its about 10 mb, wait for it, it'll start roiling out soon in other countries too..
By calibrating you guys mean to discharge the battery till the phone turns off and then recharge it completely, right? Or is there a way to wipe battery stats or something in stock rom?

yes but the best is to recharge it while it's off. Wiping battery stats doesn't solve battery drain most of the time
Meh this temperature seems so fishy. I played 3 races in Real Racing 2 on Xperia X8 - phone still cold, the exact same 3 races on HTC Desire X and it's already warm even though Xperia struggles with the game and Desire doesn't.
What battery temperatures do others get while playing games?
I get to about 42 while m playing real racing 3 all this heating but the phone doesn't reboot or switch off is because I feel our default stock kernel is configured for PERFORMANCE profile rather than the usual ONDEMAND seen in stock roms
Hey guys just want to tell you that the 99% battery bug is true. I face it. What's more suprising is that even after taking 1-2 hours to reach 100% from 99% it soon drops down to (92-95)% as soon as you start using it . Its really a thing to be worried bout
