Excessive heat when on 4g - Epic 4G General

Hello...
I use SlingBox at work ( shhh , don't tell anyone)
I believe NY & NJ area is starting to get access to 4g....
with 3g the phone stays cool...
While at Newark Airport I was able to connect to 4g...WaaaHoooo
But after about 15 minutes watching Slingbox...the back of the phone was feeling hot
Is this normal and will this be dangerous if it stays that hot?

Were you charging the phone?
The phone will usually shut off before reaching dangerous levels.

Not charging just watching The Giants kick ass..
So I'm good if it doesn't shut down on its own?
I guess it uses the cpu big time when streaming on 4G.....
anybody notice this while on 4g and maybe watching alot of youtube?

Excessive 3g/4g and full speaker use tends to heat my phone but never too much. I sit at work using skyfire to stream stuff well over 2 hours. I cut all heavy background before hand though.

My SGS got fried!

Today I had the worst surprise ever! I was playing with my SGS for around 2h straight on internet.
suddenly the phone went off. It was burning up. It drained the entire battery(it was full). I had to wait for half an hour before being able to turn it on.when I managed to turn it on the phone had wiped my settings and could not connect to the cartier network. I went to my store and they changed it for a new one.
Dit it happen to anyone else? Now I have to instal everything again.

To be honest: It hardly comes as a surprise to me, playing two hours straight over the internet (what kind of game was it anyways?) over WLAN or APN would heat up the Galaxy Really fast. Burning up would mean about 45°-50° C

Nah, I've played 3d games with wifi and everything on for more than 2 hours on the SGS with no issues. Sounds to me like his device was very faulty to begin with (or he is just trolling - more likely).
The lady plays games on mine for hours at a time regularly, often only stops because she's drained the battery. Never had any issues with it though.

Must be some faulty hardware then...
I was not even playing 3D games. Just downloading some apps from market and reading threads on XDA. Can you come up with a reason why it overheated with two hors of internet browsing?

Maybe you have a duff battery. The phone may be made in Korea, but the battery comes from China
common causes:
1. bad battery
2. connected to AC adapter
3. environment temp over 35c
4. humidity of the environment
5. you got sweaty hands/dripping sweat drops into device
The galaxy can get VERY hot.I'm
Very surprised by the levels of excessive heat from it...

[Q] EVO heating up....wtf???

Has anyone experienced their EVO heating up? Since the kick stand is metal or sumn, it gets super warm, enough to make u wonder how hot will it get. I'm a noob so I'm not sure if this is normal.
any feedback or suggestions will be appreciated.
Yes this is natural. My battery will top out at 110f with normal use. The kickstands does a nice job of heating up. I wouldn't worry.
Sent from my PC36100
It's normal. A lot of GPS use also gets it pretty warm pretty quick. Don't worry.
It is normal but you should probably not use it when it gets so hot, let it sit for 5 min and it should drop below 95F.
My evo would also get pretty warm after normal phone operations and would get extremely hot when using gps. My phone was so bad and so hot that it would begin randomly rebooting and wouldn't stop until I put the phone next to the ac for a few minutes or removed the battery for a few minutes. It made my phone reboot a minimum of 10 times a day. I got so frustrated with it that I had to get a replacement and lose my root. Now I'm hoping that stock 2.2 is rooted soon. No problems out of my refurbished EVO so far.

Mine gets warm fast when trying to find signal, other than that it stays cool.
Oh and wifi tether for two hours straight over 4g made it hit 115°f the other day.
Sent from my PC36100 using XDA App
I have no complaints about this - it stays cool for me throughout. I do remember noticing it got mildly warm a couple of times, but it happens so rarely and it's so unimportant, I didn't bother checking for anything, or even remember what I was doing on it at the time.
Both times I tried to use GPS (Google NAV first then Copilot) my phone got up 130°F and locked up. I had pull the battery and let it cool down. Disappointing at best.

Woah....130? That's crazy, surprised phone didn't fry. It'll probably have to get hotter than that. As long as the phone doesn't mess up, I will continue to enjoy this phone.
My phone generally only gets really hot in the car, when I'm using gps. Luckily I use a vent holder for it, so I just turn the air on low, and the phone is cool to the touch when I get to where I'm going. Don't know what I'll do in winter though...

Mine starts to overheat when the sun hits it when sitting on my passenger seat in my car. The phone is black, and my case is black. It's going to absorb the suns energy.
mine got really hot to the point where the led would flash green then red....135 or 145 degrees Fahrenheit I forget
I was only charging my phone for maybe 15-20 minutes

Mine does this too and as soon as I unplug it the led turns off. Think it might be the overclock. I had mine clocked at 1.2 and scaled it down to 1.9 due to phone locking up and rebooting. Sometimes I have to wipe cache and davlik cache and reflash firmware and kernel along with all my mods due the phone not going past the splash screen.
Are you running ota froyo? Ive heard alot of people complain about heat issue with it.

Guess u didn't want to get yelled at for posting elsewhere about root so you felt the need to slip it in here there was no need to mention as it has nothing to do with OP. Root will happen sooner or later grow up and wait like the others who are waiting no need to toss it in unrelated topics...we are all getting sick and tired of people *****ing about not having root! You probably made your comment up just so you could add your little remark about not having root!
Back on topic.....you guys have to remember there is a 1 ghz processor in our bad ass phones so there will be some heat unlike a computer there is not any fans or big heatsinks that will absorb the heat so with heavy use or game playing its gonna get hot plain and simple its not a defect so nothing to worry about until it starts melting in your hand....then I would say something is wrong...
Yeah, mine is running at 40 C all the time, upwards of 60 if I use the GPS.
You know...I actually hadn't noticed....and I use my Evo a lot. Only time I've really noticed it overheating is when I use WiFi tether but that's expected.
Sent from my Supercalifragilisticexpialidocious Evo!
Mine usually only gets hot when I leave it sitting somewhere without proper ventilation or when I'm riding in the passenger seat and it gets some sun. Otherwise, its pretty uncommon unless I'm really running everything at once. If you have all your radios running at max (downloading large files, checking your location on Google maps, tethering, listening to pandora through bluetooth, all at the same time) then its going to happen no matter what because all the phone's components are pretty powerful and aren't ventilated like computers due to size constraints. I know the kickstand gets hot when the phone warms up, but as long as you don't see the overheat lights, and you don't let it stay hot for extended periods of time, there should be absolutely no danger. I believe there are failsafes if it overheats for too long, but I don't know. My G1 used to get hot a lot, and it was no where near as powerful. Those were the days...
This damn issue was the fact I returned my Evo 4G to Sprint to get it replaced. The Phone was getting so hot to the point the screen was hot towards the bottom of the phone, the back was hot, and the phone kept doing restarts. My phone im Pretty sure had a defect. Not even a week after rooting thru the unrevoked method, I installed Wifi tethering App and **** went down the drain no later then a few days after. The phone began heating up and going thru 15 minute boot loops at a time. The only way to stop it was to pull the battery and let the phone cool down. The phone had to be in optimal Tower range with strong signal strength to avoid this overheating during data sessions. If i was in areas with three bars or lil lower and began running youtube, I could not go thru 4 or 5 youtube videos in a row without the ****er restarting. It was annoying and frustrating. I got a feeling something got ****ed up along the way after rooting and installing Wifi tether. I realized using Wifi tether heated the phone up real damn bad. Something must have got fried or the way the phone processed data after that was just crapping out.
So yeah my issue was way worse becuz of this overheating
I am having the same problem as you drewtorrespr. I rooted a while back using the Toast method and everything ran fine until 2 days ago. Now it seems everyday around mid day my phone heats up and starts rebooting. Not sure if its the ROM ver or hardware defect or rogue program.
How do I flash the original factory ROM back on the phone so I can take to sprint and have them look at it or does it matter. Will they just reload it for me ya think?

Good idea, I am having this issue, I had it with my S3, on the bottom of the phone, and my S4 is having it at the top of the phone.
I am going to carry on using the phone when it heats up too much, because it shouldn't damage the phone just for you to use it. If it does break, then I will send it back saying sort it out. I aint having Samsung sell a dodgy phone to me or anyone because they are just trying to keep in front of the competition. It's stupid.
Hopefully they will have common sense in the future. I have had the S1, S2 and S3 and S4, and been happy with all so far, but a bit annoyed about the heat issue on the S4 more than the one on the S3 because they have had enough people saying about it previously.

I had the S, S2, S3 and never had heat issues like the S4, only after an 1hr of GPS or gaming but not as much - I can cook an egg on my S4 just while surfing the web, what a nice feature!
When i dont touch for a while it is at 33C, but as soon as I read emails or light web browsing it reaches 44C, if then on youtube 48-55C.
when it get hot the battery % drops significantly and then when it cools down it recharge itself!
I was somewhere on S4 forum writed, this heating come most if device is on 4G (LTE) network. Try put on 3G (HSPA) or 2G (GSM) and you will see (and feel) device is much colder...

No difference at all, even tried 2G
There are times my s4 gets real hot. Can't even touch the screen! The worst it got was when I did an antutu stability test. If I remember it said like 45*c.

Normally heat isn't a problem at all.
But sitting in a bus in direct sunlight with max brightness made it totally hot!
I was only browsing, so it was due to the screen.
When I had to make a phone call I had to keep phone a bit away from my ear.
It took 10-15 minutes to cool down again.
I think every single S4 WILL get really hot under same conditions.
Don't know how if this would be same for other brands like HTC One or iPhone

Yesterday I used GPS for 15 mins on power save mode and still got at 48C, battery dropped significantly.
I haven't see many votes yet which makes me think that it is not a common problem...
Standby - <27C° Browsing, video and other simple tasks - <45C° Games - <60C° So,overheating as well. Unfortunately.

No issues at all. I have browsed for over an hour with no warm up. It warms a little when playing games or watching videos but no more than other phones ihave had and it doesn't justify the word 'overheat'.

Ideal temp 27.5 (C)
saving mode activated and nothing running in the back ground. Is it good or bad?
When mine got hot it would be from simple tasks like browsing the net for 10 minutes. At its peak, you could not touch your face with it to make a call. (Think its update fixed it though, must have been software problem for me).
No issues so far.
Do you run with auto-brightness? What conditions do you experience this in?
Hot ambient temperature, sunlight?

Auto brightness is on and working and still when i do few things on the phone the heat start to raise in an obvious way at the back of the phone around the camera area, then if i do make a phone call seriously the heat is very annoying to a degree that makes you just want to finish the call cause its very hot.
Hmm.
I guess there's a wide spread then. From perfectly fine to absurdly bad and maybe even defective. :\

[Q] Hot during calls

For some odd reason, the phone gets very hot while I am on a call. It doesn't happen all the time though. Calls are quite short (no more than 10 min).
Can anybody shed some light as to how to fix this glitch?
Cheers!
Try a different kernel and set the threshold really low. Recommend Franco. Also what's your exact temp?

yes. depending on the background temperature too, and youre keeping it insulated in your hand.. if it was the middle of winter in new york city, and you were outside talking on the phone, it wouldnt ever reach that temp. but when its warmer, it can get there fast.

gaming while charging can do it. so can streaming a flash movie while charging. plus your battery will get very hot.
Mine was just a phone call hence why I thought it was a bit too much for 5 min. I don't usually give the phone heavy use and it normally remains pretty cool. I might just still change the kernel

G2 runs HOT!!

Before I swap this thing out, I just wanted to poll you guys and see what the general concencus is.
I'm leaning towards "that's just how it is" after seeing Pocket Lints review that actually called it hot, not warm, but hot.
I have a Note 2 now and doing the same things, replying to forum post emails and browsing around, on WIFI no less, barely gets warm. G2 on the other hand becomes a heating pad...from top to bottom.

Mine gets warm gaming and after a good span on the internet.
Haven't even had mine what I'd really even call warm let alone hot.
Cool as a cucumber here. Gets a little warm when doing something really cpu heavy. Nothing I would call "hot "

How I mention already before in other posts. That is a build in feature of the phone. It is an automatic hand warmer. Specially useful in the winter time.

So warm, room temp, cold as a veggie, and a hand warmer...
But more importantly, you all don't really believe one phone is cold and the other is hot, do you?
I'm inclined to believe they're all the same temp, but we all have different tolerance levels for heat.

The only time mine gets warm, (never hot) is after some graphic intensive gaming or Qi charging for a prolonged period (Nokia DT-900)
My Droid MAXX HD was a nice hand warmer though.
Well, obviously that's the case. But I really wanted to believe there was a cooler running G2 out there...its such a great phone.

If it's running "hot" and you've already checked to make sure no apps have gone rogue, then I would definitely return it for another. We have 2 G2's bought from different parts of CA and neither have heat issues.
Hot means its eating battery too. Wouldn't be shocked if you got one from the bottom of the speed bin.

Or it could just mean the phone doesn't dissipate heat very well. I've noticed the screen in particular feeling warmer than I'm used to after some casual usage, but nothing that alarms me.
Have heard some people having heat and throttling issues with heavy graphical applications. However, it has seemed to be coming from the T-Mobile variants. I haven't heard a vzw user complain (yet)
Mine is fine (vzw)

Yeah no issues here either. and get an app that reads batt. temp at least if ur gonna compare heat levels. Mine never gets above 100 F. my s4 only got to about 96 on heavy usage. And i just returned a Moto x cause it climbed to the highest ive seen a phone, 117.

I truly believe these issues belong to people who came from older phones and are not well educated on how to efficiently use a smart phone. They load their phones with garbage apps and let it all run in the background while running game or streaming video in the foreground. They have a smoking fast phone that can run it all at once, but they are the first to cry and blame the phone when the battery drains fast or the phone gets hot.
Mine doesn't even get warm, let alone hot.

I have the VZW model. I'd like to know what game or games people are experiencing bad performance with so i can test it. Anyone willing to share?

Replacement gets just as hot. I highly doubt I got 2 bad phones, tho I can't get GPS working on the new one. Went back to the Note 2...barely warm. I am surprised by the amount of you that are saying it doesn't get warm @ all though. I think I'm just more sensitive to heat and have a lower tolerance threshold than most of you. Thanks for all the replies.
