Very warm 50°C+ - Verizon Samsung Galaxy S 4

Anybody else's phone heat up after prolonged used (just internet browsing) for an hour straight? I'm getting 56°C and the back of my phone is pretty damn warm. Luckily I have a case so its not too bad.

That's your cpu temp. If your battery was that hot, the phone would probably shut off and it wouldn't be warm it would be burning. 56c for cpu is fine. It doesn't stay that hot for long as it changes quickly depending on load

When Playing Order&Chaos with WiFi trick,Do your phone get ridiculously hot

So when im playing O&C on 3G this phone get so hot that I can feel the heat even with the otter box case on,the heat is around the top part of the phone,and the temperature reading is 115'-120'F is that because wifi is constantly scanning?..or is it because of the game constantly drain data?

I have this exact same problem I think the reason is because both WiFi and 3g is on running at the same time I think thats why it gets hot

Hopefully thats all it is cause I was goin to return it.& the 3D ac charger push a lot of power into the phone really fast(sorry I don't know the technical terms) and get over 115'F really quick
...I'm now using the iPhone charger,it charge very slow for this phone but it keeps the temperature under 110'F while playing Order&Chaos

I'm having the same issue with my 3vo. I'm hoping this amount of heat will not cause any long term damage to our phones over time.

Yeah,that's why I got insurance just incase the problem decide to show it self after 30days

Ive had this problem when playing games with airplane mode on so I am assuming the processor is the culprit. Just played zombieland usa and my 3vo got up to 110.
Those kinds of temperatures aren't going to hurt anything, i think the auto safety is at 50c or 122f. One of the problems with high temperatures is weakening solder joints. I would say 140+ is the point where things might start getting a little too hot. But the phone will shut down before it gets that hot.

I had the same problem while playing. And also I noticed my phone would get extremely hot while plugged in as well. I checked out a few threads here and figured it wouldnt be a problem. This morning I woke up to a dead evo. My guess is that extended periods at that temp will cause damage. It may have just been my evo as my friend's does not get hot.
I've played on 3g/WiFi for hours on end and my phone has never gotten very hot. Maybe a tad bit,but nothing like what you guys are describing. Idk.

new phone gets very hot

I have a new sgs2 and on the first day of using i noticed that it got very hot, is this a common thing and is there anything i can do to prevent it?
Was you using it while it was cahrging cus mine gets hot as well if i do that. Been fine since i got it months ago tho

Charging makes it pretty hot.. Make sure it doesnt have a case as that will make the phone hotter.
Also kill unused apps once in a while as the more resources you use the hotter the phone will get especially when watching videos or playing games.

it got very hot while i was just surfing the net, won't watch movies or play games on it. It was too hot i counldnt hold it any longer, wasnt charging it either.
Might be faulty. Try taking the batt out and put it back in, if still the same take it back to the place you got it and replace

It felt uncomfortable and it was hot.
I will give it a few extra days and see how it goes when I am back home.

Netflix = phone on fire?

Just recently started watching netflix a little bit, and after about 10 minutes the phone gets ridiculously hot. It got to the point where I think the phone overheated and froze.
I tried limiting the CPU to 800mhz and set it to conservative, but it is still getting very hot.
Anyone have any suggestions?
Running ICScrewed v1.5.2 (I think that's the version, whatever the latest on it).
Netflix must be running the CPU/GPU at full bore most of the time while streaming content. Unfortunately there's nothing you can do about it - it's the nature of the beast. This device tends to get really hot in extreme processing.
I'm starting to be concerned about the longevity of it. I know it's built around the 32nm mfg process so it's quite efficient but the heat is outrageous for a phone...
My phone got really hot only top left of the phone when I played blood and glory. Pretty weird. When I exit the game it cools back down like nothing ever happened. =\ I'm thinking I just got the phone at the wrong time/place.

Nothing is perfectly efficient, and a product of inefficiency is heat! The more power you use the more heat that's generated. Just like on a computer, the more CPU/GPU intensive things you do the more your computer will warm up.

Thought maybe it was the phone itself.

When I watch Netflix, I would say it gets a little warm - but I would certainly not call it hot.
Possibly another program(s) running in the background consuming additional resources?
Sent from my SAMSUNG-SGH-I777 using Tapatalk
The only time Netflix has heated up my phone was when playing on my TV over a MHL adapter, while charging, and pulling the video over data. Normally when I just watch on the phone, using wifi it doesn't heat up.
But as others said, that's a lot of power, and I expected some heat. Even at that set up, it wasn't hot enough to worry me.

Hot phone

Hi everybody. Well I'm running ics Zen 1.2 and my phone seems to get really hot. I have bat stats widget and I will wake the phone up and it will be in the 90 degree range without doing anything. So I checked CPU spy and its mostly in 100mhz most of the time. So my question is are all ics roms like this or am I doing something wrong? Thanks

I've flashed a lot of ics roms and have never experienced that. How old is the battery?
Edit: you said that the cpu is @100mhz most of the time. Is that while it's disconnected from the charger/usb?
The phone should go into deep sleep when it's not connected to usb and not being used. I wonder if something is keeping the phone awake. There are apps in the market that can show you wakelock info.
Its weird because in standby my phone will be at about 90 degrees and if I get on it to watch YouTube or get on the web it shoots up to about 100 degrees in no time and I know its killing my battery. I have the new1800 mah battery
Sent from my SGH-T959 using xda premium
100 degrees is nominal when it comes to high heat being bad for the battery. My old phone (Motorola XT720) was notorius for running hot, so I did some research about it and found that you really need to get worried when it starts to hit 50c or 120f+/-. This is when it slowly start to degrade the interior.
I got my old motorola up to 132f one time playing a wicked game of **cough**scrabble. I just backed out, closed the app down and let the phone sit for a few minutes. No harm no foul.
Just for a frame of reference, I have the MLB At-Bat app to listen to baseball games when I am at work and something about that app makes it run hot. 3rd year in a row I've had it and each year it runs hot when I am listening to a game. I have a temp widget on my home screen it and when I listen to a game it hovers around 104f. Knowing that 50c/120f is the danger zone, I don't worry about it too much.
If I can find that old thread of mine, I will post a link for you. Bunch of info in it but I can't search for it now.

Temperature of Galaxy S3

My phone seems to always be running pretty hot even when it is in power saver. I was just testing and on xda app, but my temperature was at 90 F on power saver. Is that running hot or is that just how the quad core runs?
Just by typing that message it got up to 95 and im on stock rooted Rom and stock kernel.

Mine runs very warm when its been on data traffic for a while particularly near the bottom third of the phone. I had the blue s3 before this one (now have a white s3) that ran even warmer - I would say hot
Sent from my GT-I9300 using xda premium
Yeah definitely that bottom third runs the hottest and I have the blue without a case so I'm scared that when I get a case it'll run too hot.

crashck,
If that's Fahrenheit 90-95 your talking about (30-35 Celsius) your OK depending on ambient temperature. Mostly everyone quotes Celsius, thats why I ask. Ninety degrees Celsius you're in trouble that's way to high.
Hope this Help's

My Droid 3 used to run at over 100 degrees fahrenheit... topped out at 114 once. I had to replace it... too hot in my pocket, lol.
I just turned off power saver and was doing browsing and such and I got to 40 Celcius is that something I should worry about?
Yeah I can't get it passed 40 in my house which is pretty cool but still I live in very hot climate so in scared if I take this thing outside where the air is about 39 C and with a big case on it, that it will overheat.

OK at the moment I am in an air conditioned room. Droid X2 26 °C (78.8 °F) ,Droid Bionic 21 °C (69.8 °F), the Droid X2 has a case cover both have data off ,Droid Bionic is bare naked hence the difference in temp's.
Both are sitting relatively idle. Now say I turn on data start surfing the net, downloading, playing a game etc. temps don't go much above 40 °C (104°F). If ambient temperature is higher such as living in hotter climate, no air conditioning, or outside YMMV.
These phone's will turn themselves off if temps get to high. I believe your temps sound normal.
Hope This Help's
If I do heavy tasks it heats to 41 °C... My ambient temperature is about 26 °C, which is quite high. I think 40 °C under load is normal.
Over 9000...
Phenomenal kernel helped my temps out quite a bit during heavy gaming. Battery is much improved as well, doesn't hurt to give it a try!

Some phones do run hotter than others.
Had a blue 16gb for a while and not once did I feel it get warm in my hand. Not long ago sold the 16gb one and got a 32gb and instantly noticed it got warm in my hands. Not hot but enough to take notice. In the 40's. And it's winter here.
Still, I don't worry about it too much. My S2 also got pretty warm and at some stages got over 50 degrees celcius. Still, it never let me down.

I've noticed my T999 rooted stock seems a little hot recently even though it wasn't doing much. I don't want it to be warm because it's distracting. It feels warm in my pocket, and when I grab it it feels warm (the bottom third). Each time it bothers me, because I know that heat is wasted battery.
If I was playing a 3D game or watching a streaming HD video, then OK if it gets a little warm but not if it's just sitting idle. It's going to drive me nuts if I can't make it stop.
I wish there was a Widget that could simply instantly force the phone into a "deep sleep" state where it could still receive a phone call, but not actively do anything else.
The bottom third of my phone heats up a lot when playing games, doesn't matter what game, could be a game of cards, and it would heat up the same as say... Nova 3... or Asphalt 7...
Not sure why it does it, but it does do it sometimes when multi tasking, I am running Omega v30. But always happened since I changed it from original firmware.
