Hi guys!
Just got my SII yesterday. After couple of hours use I admit that the phone becomes hot even on normal usage, like downloading apps etc. The back of the screen as well as the screen itself slowly becomes hot. If i continue to use the phone it gets worse! I'm really confused n kind of scared. I've a iphone 3gs which rarely became hot. So, can u guys please tell me if its normal with SII or its just my unit that's got some problem?
Oh, sorry if its a duplicate thread. I've seen in different websites people saying it become hot when playing games. In my case since I had my phone I didn't even install a game yet! What I did is installed couple of apps, widgets and I use mspot to sync my music(446MB) over internet.
Any suggestions and advices appreciated!
It's normal that it gets hot when you use it
You have to remember that it's a dual core 1.2 ghz proc... and Yes it's normal..
Thanks for the replies. What concerns me most is the screen becoming hot and that I don't know if anyone else is experiencing this. How about u?

a part of the issue is it is a 1 GHz CPU overclocked to 1.2 GHz, so whenever your activity demands 100% of CPU, it gets sped up to 1.2GHz and gets hotter than needed.
But yes, excessive heating is not a defect, the phone is just too thin and tightly packed to dissipate heat effectively.
Actually, i dont think it's normal
The processor sometime get stuck at 1.2GHz in my device
whenever ur phone get too hot, go and check SetCPU, if the phone dosent get below 1.2 when idle, then reboot
My guess it's a kernal thing
Not normal. Mine doesn't get hot even when gaming. It used to get hot before I updated the firmware. Now it does not.

how can it be normal when the battery doesn't get warm at all while top screen and camera lens is hot like hell, and yes i mean hot like hell. so far no firmware has fixed this problem.

I had the same issue, it dissapeared after I flashed to KE7
Thanks for the replies.
Well, it seems yesterday my phone was warming up even in normal usage but now after using the phone for over 4hrs(after full charge) and a lot of usage(videos: 60-75mins, downloading apps, music: 40-50mins, little web browsing & checking fb & mail and sync & wifi always on.....) temperature is around 30 deg celsius.
Next thing giving me trouble is the capacitive menu button which wasn't working at all since yesterday(back button was ok). Last night, sometimes it worked for a few seconds and dead again. I was thinking I should call O2 for a replacement, suddenly its working again today! Guess its a software problem.
Another thing I'm concerned about is the battery life. After charging it to 100% and after the above mentioned usage the battery level is bellow 40% after only 4hrs. Well, brightness was 0% most of the time which is ok for indoor use. Its quite funny that the phone doesn't seem to discharge faster when playing videos(at youtube & vevo) compared to browsing web. In the review & battery tests at gsmarena they mentioned battery life is very good and can last almost a day with heavy usage. What u guys r experiencing? Is it similar to mine or mine has got a faulty battery.
which firmware are you running?
I'm on O2 as u r. So I guess its the same one. If not, mine's build number is ....XWKE2, baseband: I9100XXKDJ
NB: I'm using the stock firmware, didn't root and didn't use any optimisation app like juicedefender. And display brightness is on 0%, always on wifi.
KE2 is a little buggy, you try updating to latest firmware build KE7, might solve your problem.
you can do it if you connect your phone to your pc and run kies, or reading in the dev section of the forums there is a sticky there that informs you how to upgrade firmwares.
Thanks for the reply.
I use mac and the kies mac is in beta and won't let me upgrade(option disabled). I've tried the windows version of kies(downloaded directly from samsung portal) via paralles desktop for mac(lets u use windows app in mac) but it say mine is the latest version(ke2).
And the capacitive menu button is dead again! Is it possible that this is just a software problem? Or should I contact O2 for a replacement? Its my 3rd day with the phone so I've to report ASAP if i need a replacement.
The battery also feels faulty to me. It turned from 100%-1% with only 8hr of usage as follows:
videos: ~75mins(mostly HD),
downloading several apps apps,
music: 50+mins,
little web browsing,
checking fb, rss feed & mail,
sync & wifi always on,
brightness most of the time at 0%,
fring chat: 50-60 mins
And it took 3hrs to completely charge it up. Is it normal for you guys? Or should I request for a replacement? Any suggestions appreciated!
i have debranded my phone from O2 and upgraded to KE7 from kies, but if you cant do it that way you can try upgrading thru odin.

This thread has multiple firmware versions and instructions on how to flash your phone (please note, if you decide to flash your phone, you do so at your own risk, even thuo the risk is quite small).
As for battery usage, i have rooted my phone and frozen a lot of bloatware, if i leave the phone on standby with wifi off the battery drains lest than 1% each hour, with wifi on its about 2% each hour.
Also i find that when i play angry bird a lot i have to recharge after about 6-7 hours, when i watch videos my phone heats up a little, it heats up a lot if i watch videos while charging.
hope that helps you, if not talk to the ppl at O2 to see if you can get it swapped out, but i think if you can get your firmware upgraded your battery drain should reduce and the shouldn't heat up as much.
Thank u very much for the replies. It looks like battery draining is normal for all SGS II users. Its kinda funny that playing videos over internet eats less power that browsing web(27.19min of HD video playing at vevo over wifi drained only 5% of battery!).
So now everything seem ok except the capacitive touch keys which sometimes which doesn't work most of the time. I'm just scared to use custom roms as it might void my warranty. Well, I'll try the link u mentioned and see if the problem still exists.
Thanks again
Hi all,
My SGSII heat up alot while charging. (for exactly i charge when phone have only 8%). The heat is not normal. It's more heat than while playing game.
And also it got high temp while using wifi and internet browsing between these days. Do you guys face the same problem?
SGSII is really great . But it heat up alot while playing game and turn on wifi.
Mine is a bit warm in the battery area when I begin charging the phone. But I wouldn't call it "extremely hot".
Another case is when I browse the web (that has flash) it feels a bit warm near the camera area (should be the CPU). Have not played games though.
There has been a discussion going on about that. It seems that some apps (eg Robo Defense) are not properly coded for the dual core. In addition some members also hinted, that the kernel is not yet optimized to compensate for that. The whole discussion started after a guy has "fried" his SG2 (beyond repair) while playing a game and charging at the same time. The phone still worked on AC power but no longer and battery and was unable to charge battery.
My recommendation would be,
- not to play games to long to heat up the device to much before new firmware is out.
- ...or use cet CPU to downthrottle to 500-800 MHZ
If the device heats up while charging I would try rebooting it (to get rid of processes which may still are open) or preferably charging while switched off

Which firmware are you using? I was on KF2, and experienced the phone heating up while playing games.
Updated to KF3 (stock, using Kies) rooted and all was well again. Even with excessive gaming, constant wifi on etc the phone just gets mildly warm.
There's no need to underclock etc. The heating issues just went away with KF3. If that firmware is not yet available in your area on Kies, then just put a newer custom ROM (Darky/Lite'ning/Villian etc) and try it out.
I remember whatsapping with some friends and I noticed my pocket felt really really hot. I checked and saw Whatsapp crashed. Also my battery sucked up about 30%. The phone was too hot to touch. I instantly took out the battery too let it cool down.
I never had that since. I expect it's resolved too, because I have KG1 now.
my firmware is KF2. now i decided to upgrade to KG1. is it stable now? any recommend rom?
As long as it stays below 50°C it is perfectly NORMAL.
And besides there is NO heat up issues with this phone.
Regards.
Hello
My s2 heated up alot too
so much so that it melted my simcard whilst it was on charge
also got led burn marks,
sent it to samsung lets see what they do 4 me
I already upgraded to XXKG1 and still heat up alot while playing pottery game.
This is why from the factory apple underclock their cpu's.
Samsung got the crazy idea of overclocking an already power hungry cpu.
A phone that gets too hot to touch under normal use is not fit for purpose

I have a 16g black one from Google Play. and luckily it has no light bleed, minimal give on the back but the thing just get HOT even when I am using tasks like watching video or reading Chrome like now. I monitor the Cpu temp and it is around 40 > 50C when watching video surfing the web etc. However, when I am playing 3D games and stuff it get to about 60 > 75C. I dont know if it is normal or not and is this just a software or hardware issue because it get really hot on the top near the camera and both the screen and the metal rim get hot and burn my hands. I am considering RMA it if is cant be fix through a software update though. So is can it be fix through further update or rooting and new custom rom help ? And is a case gonna help reducing the heat to my hands ?
Also if I wait for the next batch can I wait and exchange for a better one then ?

You must be the lucky one the got the special unannounced option !
Only a select few have the New HTC "Hand warmer" edition made just for cooler climates like Antarctica.
Guys, can anyone help ?
This is normal. Any processor heats up with heavy gaming. The nexus 5 (snapdragon 800) can break the 70C mark in some cases. The nexus 7 (2012 with tegra) heats to 60C before throttling. The nexus 9 does try to dissepate the heat as quick as possible (lots of copper) and feels warmer.
Samsung devices are even worse, as they start throtteling even later.
The tegra k1 is a beast of a mobile processor (gpu and cpu).

Basically, this.
Hell, my N5 actually reboots during antutu due to thermal heat and heats up a lot during gaming.
Also, the reason it heats up when watching a video, do not forget a video has to be decoded to be displayed on the screen. Hardware decoding is less intensive but some still rely on software decoding wich will heat up and cpu in a matter of minutes. So even something as simple as watching a video can be CPU intensive depending on the decoder.
As for chrome, haven't had my N9 heat up during chrome sessions. Weird
Actually, the Nexus 9 manages as only Android device in my collection to stay completely cool in netflix HD streaming. 10% battery usage after 90 minutes. Compared to the other devices that use up at least 40% of battery during the same time.
One drawback is the 4:3 screen, which still makes my Note 10.1 beter for netflix (or movie viewing in general)... But the Nexus 9 is the only tablet I even consider using in portrait.
Same problem here, especially with Chrome. I've rooted my device, I don't know if that could have something to do with the heating...
Chrome Beta seems to have really helped with the heat issue on mine. I still get a lot of heat with gaming but that seems to be it.
The n9 was the first device I've ever had that heated up on me while browsing in chrome. This is NOT normal. I RMA'd it and picked up a shield instead... I don't know how these devices passed QA with all the issues they're having.
My personal opinion, is lollipop isn't quite ready and many apps aren't either. I'm waiting for all to be updated. The heating problem will, I'm sure, be taken care of.

Hopefully before black friday . The Sheild went up last year and I'm expecting it to do the same this year, not sure if I should go ahead and buy it or wait for the Nexus 9 to be fixed.

I noticed the other night a considerable warming by the camera area and all I was doing was browsing the Internet. So as I was using Chrome I stopped, and browsed with FireFox, the tablet cooled completely down. Even watching YouTube it was barely warm.
I think something is wrong with Chrome and it's causing a loop somewhere in the code ramping up the CPU causing it to use a lot of power and that equals waste heat.
Playing games also has the same effect, it ramps up the CPU. The CPU is probably rated to continue working up to quite a high temperature before it needs to slow itself down to allow to cool, but when that heat causes the case to become very hot, it should back off the speed and so keep itself cool a long time before it reaches any of it's own temperature maximums, the trouble is keeping the case cool means the CPU can't maintain high performance for very long, so what's the point of a fast CPU.
Really tablets are not the best designed devices for 3D type game playing, or anything really that needs to use a lot of CPU power over and above the occasional burst.
I wouldn't be surprised once all the benchmarks have been done and published, if a software updated doesn't fix the heat problem by throttling the CPU quicker, and running it with realistic performance characteristics that being sandwiched in a very thing plastic case with no vents or active cooling requires.

I second the chrome beta helping. I disabled regular chrome in app manager and installed the chrome beta and have had a significant boost in battery life and decrease in heat while browsing.
Mine only gets warm with heavy games

Do you still notice any warmth using Chrome Beta? Or is it relatively cool? I have tried both Chrome Beta and Dolphin, and I am still noticing a good amount of heat. It's actually cooler watching Netflix than it is doing any sort of browsing whatsoever.

Saturday when I switched to the Chrome beta for the first time the heat was the same as before. Yesterday and today it has been noticeably cooler. I'd say the tablet gets just warm enough to notice a difference from it's ambient temperature when using chrome beta. I've gotten slightly better battery life but i'm still only hitting 4 hours screen on time when I hit 15% battery which is about a 1 hour increase from before using chrome beta.
I think chrome is still in need of major optimization because as you said when I use youtube or netflix I get much better thermal and battery performance. I did notice today that chrome seems to be performing extremely well on page loads and interactivity with javascript elements etc. I threw as many complicated sites as I could at it and made sure to go to sites I that hadn't been cached before on the tablet and it was super fast. It actually impressed me with it's performance which I wasn't expecting. Now it just needs to get more battery efficient and it will be perfect.

Thanks for the details. It's a shame that browsing is so poorly optimized. That's my main purpose for a tablet. I've just been on Dolphin the last hour and yep, heat is still pretty strong and my battery has gone down quite a bit. But before that, I was running Netflix for several hours just to test, and was up to about 5 hrs SOT. But I typically don't watch much Netflix, so that doesn't reflect real-world usage for me at all.
Yeah it's a little disappointing but the improvement I saw from chrome release and chrome beta is promising. My browsing experience today aside from heat and battery issues really made me like this device. The performance really blew me away. It felt more responsive than my i7 desktop.

Hi everyone, I have a Samsung tablet SM-T325, Android 4.4.2 vanilla
Last month while I was playing some basci game on it, the tablet suddenly restarted.
I tried to play while the tablet was charging and nothing happened.
To ascertain the problem was not the game I installed Antutu, then I charged the tablet to 100% and then performed a stress test.
It rebooted when the test was at 3%. When I connected the tablet to the charger it was able to finish the test. When it reboots the battery level is almost the same (about 2% less).
Can you help me to figure out what could be the problem?
Thanks in advance
Not strong enough.

Let me lay it clear in Simple Words.You tablet is not Powerful Enough.The CPU GPU and other specs are outdated.There's a protocol in Android 4xx that States "When thy shall play Heavy Games Thee shall Restart"Obviously it was Changed to "Whe Thy shall Play heavy Game it will exit thee game"
So,Limit your background usage and apps.Backup and Reset to Wipe every Mess and leftover things and Start fresh.Or Root it and Flash a Custom Kernel to Over Clock the GPU and CPU this will make the Device more powerful with the cost of extreme heating and a Truckload of Bugs.
Or Buy a Device with Higher specs.

Not sure if you guys experienced this, but I was playing around with the Google Assistant in Akinator and my device temperature went sky high up to the point where the phone notified me that it has to dim the screen and take action against that.
I set my phone to the max resolution and framerate, and I also keep it in the silicone bumper they shipped.
Did you guys ever see this happen too?
P.s. it wasn't charging.

No issues here, in fact I've been impressed with how cool it stays. Hammered some benchmarks and it barely went over 45c
This is obviously just sat idling now but I've been using the phone for over an hour on max resolution, 90hz and no power saving.
I faced the same in two instances. One, when I was transferring files through Xender. Second, when my Google Photos were syncing with cloud.
Received the same notification as well. The phone was untouchably hot and battery drained a lot faster.
My assumption is whenever there's a big load of data transfer, the phone turns unbearably hot.
I really don't know why you're experiencing this, I have barely put my phone down today and it's been ambient temperature at best including when playing COD. I've got a fair sized file transfer going here and temperatures are absolutely fine
I should also point out before my first screenshot at 10am I had 17 hours standby. I've used my phone on and off all day for web browsing, music and some gaming and in the second screenshot 10 hours later I still have 30% battery remaining and it's not once gotten hot at all. Running 10.0.3 since yesterday afternoon.

Great to know that, I have no clue why we are facing this then. I was hoping it will get better with the future software updates.
Also, there's so much less to read about OnePlus 7T Pro compared to OnePlus 7 Pro. Seems a lot of people did not go for it hence the development is really less, I hope it catches up soon. Waited for so long to get a OnePlus device.
I am facing the same issue, sometimes I'll be doing literally nothing but messaging and the phone will become uncomfortably warm like in the 60's - 70°c also my battery life is quite lower than expected around 4 hours SOT I'm going to try a factory reset and hope for the best
Having exactly the same issue, brand new unit. Delivered today, CPU temps reaching 85 Celsius ! (updated to latest Android 10, not charging, not playing games or doing any intense tasks).
I own a OP6 and OP2 and never felt such uncomfortable heat while holding the phone, hoping its just a deficient unit and not a general problem with the OP7T Pro.
Pic attached.
