[Verizon Samsung Galaxy S 4] jayochs:
jus got my s4 yesterday.. great phone! but I'm noticing that just doing normal stuff really heats her up. my s3 heated up as well, and it was on the bottom of the phone making it uncomfortable. but the s4 gets warm, or hot, on top. the ear piece gets hot and so does the camera area. I presume this is where the antennas are?

anyway how's everyone else's? good thing I don't talk on the phone often because if that thing heat up my ear I'd return this phone asap lol
[Verizon Samsung Galaxy S 4] Fu5ion:
It may be your service area. In places where theres low or spotty service or a fringe from 3g to 4g, the radio has to work harder, thus heating up.
[Verizon Samsung Galaxy S 4] Diversion:
Mine gets hot/warm doing normal crap too.. kind of a bummer because the Note2 doesn't get this hot.. just warm at times. I'm assuming this is where the CPU is located, near the center top area where it gets warm/hot.

It's something about Qualcomm it seems.. all of their CPUs love to heat up fast.. seems like the battery percents also drop fast whenever it warms up.
[Verizon Samsung Galaxy S 4] jayochs:
funny thing is that my DNA never gets hot, and that's the snapdragon quad core. and hwen it gets warm, it never breaks 40 degrees C.

the gs4 easily hits up to like 37, 38 degrees C....but even when my DNA is that hot, it doesn't feel that hot. the heat dissipation in that must just be better than how samsungs is. kinda worries me, but my gs3 was just as hot.

i put ktoonz kernel in, which seems to not have the CPU running at full speeds like the stock kernel does, so i think that may be helping. i might flash a custom rom next.
[Verizon Samsung Galaxy S 4] Evocm7:
I'm stock rooted so I can't say for other roms/kernels. Mine doesn't break 35c which is a miracle to me coming from the heat plagued rezound where 45c can be achieved just browsing xda for 20 mins. I didn't like how hot samsungs 2amp charger makes the s4 whole charging (even during idle about 35c) so I use my htc charger which is the same 5v but only 1amp. Charges slower but will increase overall life of the battery
[Verizon Samsung Galaxy S 4] jayochs:
ha i didn't even open my s4 charger yet; didn't realize it was 2 amps..i was using the DNA charger too lol

so never over 35? are you on 4g all the time, or wifi? i'm always on 4g and i can easily hit 40. blah. but again, my s3 ran hot too, so i think it's just a samsung thing.

and yeah the rezound was a heater lol i had one.
[Verizon Samsung Galaxy S 4] Evocm7:
I know I remember seeing you over there. :D nice to see some familiar people here. That's on 4g outside yesterday 90 degrees outside Internet browsing and some YouTube for an hour straight. The hottest ive seen was 42 but that was in my car with the sun beating on my pocket with the phone in it.
[Verizon Samsung Galaxy S 4] Serk102:
The only time mine ever got hot is when I used a sleep tracking app which required the phone be on all through the night. Being under my pillow probably didn't help either, but it the battery temperature apparently got up to 45 degrees celsius which made the phone stop charging too.
[Verizon Samsung Galaxy S 4] jayochs:
good to know it stops charging at 45...the rezound didn't lol.

mine right now is sitting at 33.6 degrees C. i'm copying like 6 gigs of music to my sd card. thing is, the earpiece and camera are very warm..the entire top of the phone. can't imagine how annoying that must be when you're talking on the phone...good thing i never make phone calls :\ lol

if you look in system panel or something, you can see that all 4 cores are like always working....and the CPU speed is hardly EVER below 700mhz when the screen is on..i find that odd. my DNA would easily hit down to like 300. it seems like the s4 cpu is always doing something..it's always above 50% on mine, never below. i find that pretty odd...bc idk what it's doing in the background. i put on ktoonz new kernel and it helps a bit, but it's still running often.
[Verizon Samsung Galaxy S 4] jayochs:
god i'm really hoping there isn't a bad batch of ones that get hot. i went through 3 at the store to pick the right one...two of them actually had banding issues on the screen....SERIOUSLY?! i thought we were past that on AMOLED?!?!

they ALL have this very faint veritcal line towards the bottom that's like white when you're looking on a gray background.....every single S4 i've seen. it's crazy. idk wtf it is. this one had it, but the least amount compared to the other 2, but i think i have a tiny piece of dust under my screen. is it really that hard to ask for a piece of technology that's perfect anymore? lol
[Verizon Samsung Galaxy S 4] Evocm7:
Do you have power saving mode enabled? I do and trickstermod shows it rarely using anything above 1.3ghz which I like very much lol. Im guessing the gpu and cpu is up in the camera region as it only gets warm on mine when watching videos or having the screen on for long periods.
[Verizon Samsung Galaxy S 4] jayochs:
nah i don't use power save....and duh i forgot to download trickster haha i bought that app ages ago
[Verizon Samsung Galaxy S 4] Evocm7:
Found this article too. http://www.phonearena.com/news/Is-your-Samsung-Galaxy-S4-overheating_id42616

I haven't seen this white line you speak of????
[Verizon Samsung Galaxy S 4] Diversion:
Holy crap I was tethering using my S4 and charging it up at the same time.. It felt dangerously hot.. I sure hot this doesn't fry the phone, i'm pretty shocked there's not a safety circuit that turns off charging when it gets this hot. This worries me as I rely on tethering for work pretty much daily.. it did seem like once it charged to 100% the heat level went down a bit.

My Note2 gets warmish when tethering and charging.. no where near the heat level of the S4.
[Verizon Samsung Galaxy S 4] jayochs:
next time you do it, check the temp with an app like system panel and report back how hot it was.
[Verizon Samsung Galaxy S 4] Evocm7:
If you have a different charger, use that one Samsung gives us a 2amp charger out of the box which is nice for fast charging but is going to cause shorter overall life of the battery and hotter temps. I use my htc charger and it keeps it much cooler, especially when using it while charging
[Verizon Samsung Galaxy S 4] whichonespink73:
I haven't noticed any heat problems thus far. Sometimes the back under the camera gets a little warm but nothing out of hand
[Verizon Samsung Galaxy S 4] aldread:
It runs cooler than my gnex!
[Verizon Samsung Galaxy S 4] imablackhat:
Gnex and s3 always ran hot for me when torrenting or gaming. My note 2 didn't have this issue. Well because it was probably huge. And now s4 issue remains. Maybe the size of the phone? It always gets warm where the cpu sits on the board. Not a huge deal. I never let mine get scolding hot. But it'll get warm.
[Verizon Samsung Galaxy S 4] GrayBoltWolf:
Oh, so you've come here to complain now? :D
[Verizon Samsung Galaxy S 4] jayochs:
want my blue s3? ;)
[Verizon Samsung Galaxy S 4] GrayBoltWolf:
$25. According to you it is worthless. :)
[Verizon Samsung Galaxy S 4] BennyJr:
Im pretty sure android has a built in shutdown at 60C but that's very very hot. N4's used to get their easily with snapdragon's. That's why I try and avoid those cpu's. My brothers DNA gets hot just on the web for a few minutes.
[Verizon Samsung Galaxy S 4] AshtonTS:
Nobodys N4 breaks 60. Highest I've seen is like 50 at most.
[Verizon Samsung Galaxy S 4] BennyJr:

Its a pretty harsh test but he has some good data on it too.
[Verizon Samsung Galaxy S 4] icepik1234:
I've never really had any issues with it getting hot. The hottest I've gotten mine was while playing games for an extended period of time. Even then it felt way cooler than my Evo did just charging with the screen off. That thing could cook an egg on it.
[Verizon Samsung Galaxy S 4] mexiken:
My battery temp is 42 with light charging as it's charging with a 2 Amp charger. My CPU temp is 55-61 =/

Why is everyone reporting battery temps and not CPU temps????
[Verizon Samsung Galaxy S 4] Evocm7:
That's fine for cpu. Battery is the main concern. I don't like 2amp chargers. Gets too hot. I use 1amp
[Verizon Samsung Galaxy S 4] jayochs:
because the cpu cools down extremely fast. mine will easily hit 50 then back down to 40 in a manner of seconds. battery temperature is what stays there for minutes until the phone is off and cooling down. battery temperature is also what's going to cause drain in battery. I'm watching my battery drain right now after about 30 minutes of constant use from 97 to 85 and my battery temp is like 36. i had it idling for like 5 hours this morning, only dropped 3 percent. pretty good. but obviously the second I started using it, it dropped and got warm. 36 seems to be what my battery temp is always at. it's warm and annoying lol
[Verizon Samsung Galaxy S 4] jayochs:
after using the camera outside today (it's warm, probably like 88) for like not even 3 minutes, my temp jumped up to 37 degrees C from like 30, and the CPU jumped up to about 60.

PSA: using the camera makes this phone really hot.

actually, doing anything on this phone makes this phone really hot. lol
[Verizon Samsung Galaxy S 4] :
It's normal for heat to be generated during electrical current. Look at TV s, DVRs,l, or whatever else. Its normal... if your phone starts freezing or resetting, then its a problem.
[Verizon Samsung Galaxy S 4] jayochs:
no i understand this, just comparing it to other phones, they don't get hot simply from a few minutes of camera usage...aka my DNA lol. the rezound was a heat beast..mine never froze up or overheated or anything, but it got HOT...and now the S4 does exaclty the same thing. kind of sucks. i hope maybe it's a software thing wtih touchwiz.
[Verizon Samsung Galaxy S 4] jayochs:
I KNEW I WASNT CRAZY. this must be why the brightness keeps dropping on white backgrounds for me, as if that screen tone thing is checked off.... this is so annoying. this damn phone gets hot and then the display tries to compensate. stupid samsung.
[Verizon Samsung Galaxy S 4] imablackhat:
I always use auto brightness.
[Verizon Samsung Galaxy S 4] Evocm7:
There's no possible way your s4 runs as hot as your rez lol
[Verizon Samsung Galaxy S 4] jayochs:
i think the hottest my rez got was 45. the GS4 hits like, 38. but i'm starting to realize something after flashing cleanrom.....

i think it's just because i awlays use 4g. i think the 4g antennas are making it super hot. my dbm in my house is always around 102, that's not that bad, and it didn't make my DNA hot..but it made my S3 hot and my S4 hot. i switched wifi on (i'm the furhtest room from my router, so the signal sucks..) and doing stuff on the phone only has it get to like 30-32....crazy.
[Verizon Samsung Galaxy S 4] GrayBoltWolf:
Duh. That's what made the Rezound so hot.
[Verizon Samsung Galaxy S 4] jayochs:
my rezound would get hot by just looking at it.

seriously, i used wifi all the time on the rezound, not 4g..because when i had the rez, we didn't have 4G where i lived lol
[Verizon Samsung Galaxy S 4] GrayBoltWolf:
Well, that's the only time mine gets hot.
[Verizon Samsung Galaxy S 4] Evocm7:
I pretty much have to be in direct sunlight for mine to get to 38. I've never seen it touch 36 during use. 35.7c seems to be it's happy spot even with 4g. Is 36-38 really that hot? Maybe I'm just so used to the rez that it makes this feel like nothing. Even my og evo normally hit 40-42
[Verizon Samsung Galaxy S 4] jayochs:
i can't believe how much cooler this thing runs on wifi. I've been using wifi all night, and even though my signal isn't great in my room, my phone isn't even going over 32 degrees Celsius even after like am hour straight of playing on it. so i guess it's the 4g antennas that are doing it...
[Verizon Samsung Galaxy S 4] jayochs:
just watched 30 minutes of Netflix on wifi... 29 degrees c. wow. lol that's awesome. glad I somewhat solved my problem....
[Verizon Samsung Galaxy S 4] mexiken:
Ah, makes sense. Thanks for the explanation guys.
[Verizon Samsung Galaxy S 4] Diversion:
After switching to CleanROM and Faux's M kernel and just leaving the phone on powersave I really haven't had any issues anymore.. and my battery life is pretty ridiculous now, getting closer to my Note2.

Once you realize that powersave is still faster than the Note2 on full blast, it's pretty hilarious how powerful the new Snapdragon 600 is (which is close to a real A15, or close enough).
[Verizon Samsung Galaxy S 4] rushless:
10 points in seconds? Not possible, unless you are converting a few minutes ;) No way the device could dissipate that fast due to the size, material (plastic not good for heat displacement) and lack of effective heat dissipation in the first place.

Even if you turned the device off, it would not be seconds, as in a few or several.

The S3 gets hot, so of course a device using the same fabrication size but faster cpu and gpu along with pushing twice the pixels will run hotter, with comparable use.
[Verizon Samsung Galaxy S 4] jayochs:
yeah i realized i was wrong about that but never updated lol :p

it'll drop down a few degrees in a few seconds, but nothing as drastic as 10.

it's pretty much 4g that runs it hot..when on wifi, i don't break 33ish ever. on 4g, i can hit up to like 37
[Verizon Samsung Galaxy S 4] Piero914:
I don't have one but my friends gets hot as hell.
[Verizon Samsung Galaxy S 4] jvcjbl:
Mine gets noticeably warm around the ear piece and the top portion of the screen. I can feel it in my pocket getting warm/hot. Granted I have been visiting a lot of Rigs in rural areas that have little to no service but I've never had a phone get this hot before.
[Verizon Samsung Galaxy S 4] MutantPlatypus:
Mine get's hot, too. It also cools off pretty quickly, as mentioned above. (I assume the thermometer is directly between the CPU and the heat sink, so the thermometer will cool much faster can the parts you can touch.) I'm not too worried, because the heat is pretty far removed from the battery, even when I'm charging AND loading the CPU/GPU.
[Verizon Samsung Galaxy S 4] liathus:
I haven't noticed any heat problems, but I mainly use Wi-Fi and am really a pretty light user. Running cyanogenmod.
[Verizon Samsung Galaxy S 4] SmokeyMon:
I have run many roms and a few kernels and have not had any problems with heat.
[Verizon Samsung Galaxy S 4] Easton999GS:
Jayochs whats up I remember you from the Rezound forums back in the day. I loved that phone but anyway, I have an AT&T galaxy S4 and mine does heat up a **** ton when im using it a lot, more CPU intensive tasks instead of GPU. I overclock my GPU to 600MHz and it still stays cool but god forbid I overclock my CPU I can fry an egg on the back of my phone. it spikes up to 50 degrees on average at least. i basically have to use a custom kernel with a aggressive conservative governor and the heat throttle turned up to 70 degrees to have my phone work how i want it.
[Verizon Samsung Galaxy S 4] DarkMenace:
I use Elixer 2 & Elixer 2 Widgets and noticed to increased heat on the battery.
[Verizon Samsung Galaxy S 4] jayochs:
hey Easton. did your rezound get hotter? lol mine did! mine isn't too bad lately since I use wifi more.. but idk man.. this thing gets hot!
[Verizon Samsung Galaxy S 4] CreativeEmbassy:
I haven't noticed any heating problems on mine; it gets slightly warm, but never "hot". And I've been using the hell out of it since I got it. No issues.
[Verizon Samsung Galaxy S 4] DroidHead214:
That is something I notice too. My phone get hot too rooted and stcoked
[Verizon Samsung Galaxy S 4] DarkMenace:
I'm nat 95 degrees on my phone right now. Using Elixier 2 for various monitoring.
[Verizon Samsung Galaxy S 4] Easton999GS:
My S4 definitely gets hotter than my Rez ever did. Using Ktoons kernel it doesnt get hot unless i overclock though. Im talking about stock kernel right here lol.
[Verizon Samsung Galaxy S 4] THATTON:
I returned my first one for overheating and major lag. It would hover right around 105 F idle. Obviously it got hotter than that when I started doing anything else- YouTube, Twitter, phone calls, etc.
[Verizon Samsung Galaxy S 4] Diversion:
I've had three S4's to play around with.. It does seem like the heat does have a variance between devices.. but they all got decently warm under use.. The only thing to combat it is to not run a bright screen. I'm actually surprised these S4s barely warm up when hammering LTE during a download.. Grabbed a 1.6 gb rom at over 2mb/sec over LTE and it barely warmed up. It seems the screen is the biggest heat generator.
[Verizon Samsung Galaxy S 4] EVOme:
Mine heats up more than any other phone I have had either.
[Verizon Samsung Galaxy S 4] DigiDave:
Former Rezounder here too....

Just got my new S4 last week and for me the highest temp I've seen is 99 F and that was after hours of messing with my phone on stock ROM (no root). My Rezound would reach 125 F after like 20 mins lmao (rooted ROM)! Don't get me wrong, I loved the Rezound but it got hot really fast.
[Verizon Samsung Galaxy S 4] oilfighter:
I thought the S4 was HOT on stock ROM, now on CleanRom 1.3, it's not so bad, about the same as S3.
[Verizon Samsung Galaxy S 4] DarkMenace:
The heat looks good on mine, Sitting at 84F right now.
[Verizon Samsung Galaxy S 4] zxsix:
Which system info widget are you using there?

I'd like something with those cyan colored icons and preferably transparent background.
[Verizon Samsung Galaxy S 4] DarkMenace:
Its Elixier 2 & Elixier 2 Widgets. You need both for it to function. You can customize everything. There is a transparent option also.
[Verizon Samsung Galaxy S 4] Eric214:
I just finished watching the season finale of Game of Thrones on HBO GO on sidi and brightness at 100% full and after 102 minute episode, my s4 never went above 86F.

I think that's really good. I can barely tell is getting warm

[Verizon Samsung Galaxy S 4] s4noob:
Mine is getting very hot when im on it. Cools off quick tho
[Verizon Samsung Galaxy S 4] ahatzz11:
I've noticed that my phone gets hot when I charge it ever since I got my case. I never really had issues with it before. When I unplug it it takes a few minutes before it cools down, but I have not yet noticed it heating up when I am just using it. So far so good!
[Verizon Samsung Galaxy S 4] Footbaggin:
I just exchanged my last GS4 yesterday because the screen had a dark splotch on it which drove me crazy. 10 days into my buyer's remorse period I finally decided it was too big of a deal for a $700 device and now my new one has this heat issue.

The last GS4 I had stayed cool and had fantastic battery life. My new one has a perfect screen but it gets really hot at the top of the screen (and the back around the camera) and noticeably worse battery life. I kind of wish I had the other one back now because an annoying dark patch on the screen is definitely the lesser of these two evils. I guess I'd send it back to Verizon for a third try but I'll probably wind up with a unit that gets hot, has poor battery life, has an uneven screen and won't read SD cards or something.

I'm thinking it's best to just stick with what I have, sounds like my situation is not unique.
[Verizon Samsung Galaxy S 4] oneandroidnut:
They give you a new one or certified pre owned? I have a replacement coming for the heat issue. They lady at Verizon said should be a new one since phone is only like a month old and if not call and try to get a new one. I sure hate refurbished
[Verizon Samsung Galaxy S 4] Footbaggin:
Mine was a new one because I returned it in a Verizon store. You're allowed to do that once in a year according to the customer service rep I spoke to on the phone.

Not that getting a new one had done me much good... this thing gets HOT!
[Verizon Samsung Galaxy S 4] AmericanCon:
Isn't it somewhat normal for it to get hot? Every android phone I've had or a friend has had have all gotten relatively hot at some point.
[Verizon Samsung Galaxy S 4] oneandroidnut:
Oh ok cool and I hope I get a new one! And mine gets hot to man the lady in the store didn't even want to feel how hot it is was it was like pulling teeth to get her to feel it she was shocked lol

While I agree yes mine gets hot the camera area and top of screen. Talking on the phone burns your ear lol and note, s3, DNA all didn't do this and I had a rezzy and this s4 gets as hot as it in hand to me
[Verizon Samsung Galaxy S 4] jayochs:
eh, dna never got this hot. my rezound did though lol... gnex didn't really either. the phone gets hot mainly from cpu usage. using the camera will get the cpu easily up to like 65 degrees c... i did it last night. crazy. was only using the camera for like 7 minutes
[Verizon Samsung Galaxy S 4] joefrog1996:
To those who have the overheating issue. Does if happen at anytime, or just when your playing a game, or on the charger? Mines gets hot when playing games (up to 106°), is that normal or do I have a bad unit?
[Verizon Samsung Galaxy S 4] oneandroidnut:
Mine gets hot after several minutes of anything. I can have a Google hangout chat or Facebook conversation and it gets hot within minutes. Games get very hot and charger gets warm but not hot unless you are using and charging. I don't have exact numbers though for you sorry I know it gets hot through my neo hybrid case though
[Verizon Samsung Galaxy S 4] joefrog1996:
Alright, I think my units fine. Thanks. I use battery bot to check temp. I'd appreciate it if you could use it and tell me how hot it gets. Just curious
[Verizon Samsung Galaxy S 4] mattymillz:
the heat on mine is just fine
[Verizon Samsung Galaxy S 4] jayochs:
overall, she's just a very warm running phone. thankfully while on phone calls it doesn't get too hot, though. i was on the phone for 4.5 hours last night, and it hovered around 86 degrees F which is like 30ish C i think. not bad at all.
[Verizon Samsung Galaxy S 4] oneandroidnut:
sure man. i will download asap before my new one comes tomorrow and what is your heat on so i will have something to compare it to?
[Verizon Samsung Galaxy S 4] joefrog1996:
106° Fahrenheit, thanks
[Verizon Samsung Galaxy S 4] oneandroidnut:
After all night of charging I just got up and pulled of charger and it's 89° and I just unlocked it lol seems high huh? I will monitor it through the day
[Verizon Samsung Galaxy S 4] HPeterson:
When i'm using my phone pretty heavily, it gets up to around 50 degrees Celsius. Other that that it says very cool.
[Verizon Samsung Galaxy S 4] DarkMenace:
I was at 105F the other day sitting passenger with the top down and maps running. The safe operating range is 130F so I think people are worrying to much. This was told to me by Verizon.
[Verizon Samsung Galaxy S 4] graptharshammer:
I don't have something to monitor the actual temperature, but I had it plugged into the wall with the provided cable / charger while I was setting the phone up. It got so hot it was actually painful to hold and even painful to touch the screen. I haven't seen that behavior since, but I'm pretty shocked that it's even possible.
[Verizon Samsung Galaxy S 4] oneandroidnut:
Yeah that is crazy and

Been using for a few minutes in the car at lunch with ac on checking forums etc and jumps up to 93°
[Verizon Samsung Galaxy S 4] mitchallica:
The only time I notice significant heat is when I'm in a low coverage area, so I just put it on airplane mode at that point.
[Verizon Samsung Galaxy S 4] DarkMenace:
I do Airplane mode when I go to psychical thearpy. They don't have service downstairs.
[Verizon Samsung Galaxy S 4] rushless:
Another option is to just turn off the data radios since that is what causes the heat and kills the battery. This allows calls and texting still and nice fallback in case you forget to turn back on from airplane mode. It is just as simple to do and in the pull down menu like airplane mode.
[Verizon Samsung Galaxy S 4] oneandroidnut:
Shouldn't have to do that on this high end of a phone
