Epic gets very hot when I use 3G or 4G - Epic 4G Q&A, Help & Troubleshooting

My epic gets very hot when I use 3G or 4G, It is hot to the touch and situated at the top of the phone near the camera.I have 4 bars and no signal problems whatsoever. Does anyone else have this.
Thanks

Yeah. It'll do that. Especially if you use the connection for extended periods of time. It's nothing to worry about.

Mine doesnt get hot like at all.
The only time is gets hot is if im charging while playing a game or charging while it on like leather furniture or cloth. Other wise those are the only incidents i have to see where it gets hot.

Anyone else have anything to share?
Thanks

Download an app like battery indicator or spare parts and tell us how hot it gets. These apps have a temperature indicator on them. See exactly how hot it gets. Mine only gets hot when it's charging and I'm running high CPU things on it but I've never felt it get hot like you described off the charger.

I just checked today it was 42 Degrees Celsius. What are you getting?

I just bought one of these phone. I have also had the issue with the phone getting hot while on 3g. Streaming audio it gets pretty hot on the top half of the phone. The battery doesnt get hot at all. If i use netflix, it get very hot on 3g but doesnt while on wifi. Could this just be an issue with the radio on the phone getting hot?

The processor is working harder to pull the data while on 3g and that is why its getting hot.. imo if its not getting above 115 degrees really nothing to worry about... just don't use it for hours on end while its that hot. Also flipping the phone onto the screen while its streaming seems to help with the temperature also...

how hot is your desire?

Just got a replacement phone from htc due to a problem with my previous one. The thing with this so called new phone is the it gets very hot. Even the screen feels hot to the touch. All the aluminium parts are worse, tracking ball is also hot. Anyone with the same problem or is it just me
must say i have not noticed any heat issues with my desire. my wifes is fine and my sons is ok too
Mine is cool and only the battery and the bottom part(CPU there?) feel a little hot with heavy usage.
Mine can get pretty warm - probably warmer than my old touch pro - but its slimmer, more powerful and a bigger screen which i guess uses more power.
looks like i am the only person with this problem. Last night while using the phone it really got too hot to handle. I had to put the phone down to let it cool off a bit before using. Looks like i got to send HTC more e-mails again. Damn...
About 90F from the temp reading ... thats on an idle day. When doing stuff it can go up to 100-120.
Mine is getting quite warm when charging and using it at the same time but never really that hot that I couldn't handle it. Other than that it stays handwarm or cool when idle. The Desire getting as hot as you descibe it does not feel right for me, except you're using it in the desert?
Mine gets hot too.. just reading some news and the battery is 38C. Also device feels hot. Especially the lower part of the screen and back. No reboot though. Is this normal?

Mine gets quite hot when I oc.
How well do our devices toletate heat? Has anyone spoke to the allmighty allknowing HTC about this?
What is their view?
I think my Desire is cool... muahaha..
Yeah, bad joke. .
In real, it is warm when using wlan and some bits moving around, but it will get very hot if i use 3G/hsdpa.. Actually it start to warm up badly even with very light data traffic... Connection is ok with allmost allways full bars.
Nice to have this HOT device...
Aargh... bad joke day i have...
Edit: forgot to say it didnt warm up like this when oc and stress test. Have not tested/used GPS so can not say anything about it.

Pulled down this app called tempmonitor from the market. So far the hottest that i managed to get for the battery temp was 45degrees. I think that is pretty hot.
My phone was 160 the other day in the car while listening pandora.
Sent from my HTC Desire using XDA App
hmm yeah after some internet browsing my battery temp was at 40 degrees celsuis the other day. It did feel hot but then again other smart phones heat up too i guess so i have come to accept it
Ever since i started to use the desire i have been having problems with my sd card. I dont know why but i keep getting this error message "sd card damaged" i got to reformat the card every time. Data loss is making my blood boil, i never had this problem when i was using this card with the touch pro2. Could it be that because of the heat that the card keeps getting damaged?

Heat on the top right of the phone

I was playing games on my phone for an hour or two and noticed in the top right of the screen about where the power button is, it was getting really hot. Just on the screen face. I took my cover off and felt around the back and it was cool. But it was getting noticeably hot when touching that part on the screen. Has anyone else noticed this?

I'm worried about Heat for my phone E4GT too.
Idle, it's around 27c, which isn't bad at all.
But during usage it jumps to 34-37c, and wireless tethering causes it to go 49c.
My GTX 570 runs idle at 37c, that's fairly cool for a GPU but my knowledge in phone hardware isn't nearly as great.
What kind of temps can this phone handle?
Same issue here I m so pissed

The highest mines gotten so far was 116F but it was charging with my HTC charger and i was playing a game. The odd thing was the main part that was really hot to the touch was the top of the screen near the ear piece and it wasn't just warm it was hot. But that's only happened about 2 times now.

Third phone and still experiencing heat issue
I have changed my phone twice at Sprint and, for each one of them I have experienced the heat issue. Sometimes, the temperature goes as high as 53 degrees. I am not sure what exact combination causes this problem. I have seen it with or without 4G on - charging it makes it worse. Rebooting seems to help.
Makes me worry about this phone. I really like this phone but I definitely don't want to deal with a heat issue.
Heh, just try using this phone with zedomax's kernel set at 1.5ghz and playing Dungeon. Hunter HD II for an hour . . . it gets blazing hot! No performance issues through, only immense heat

Nitro getting HOT after LTE activation

Well AT&T has activated LTE in the Orlando area and it sure is fast. I have noticed that when I browse or use LTE data my Nitro has been getting quite warm. Any one else in LTE areas having problems with overheating?
only time it gets hot for me is when it's using GPS, LTE, and charging at the same time.
dtla here and no lte........yet.........it's coming any day/week/month year now.

my phone gets hot while playing games.Lte still not available in my country
u can get higher than 1mb per second on 4g without lte on, i only turn mine on if i'm watching high res youtube videos, which i rarely do over data, usually only on wifi.
by the way it's normal for the phone to run a little warmer with lte on, but it shouldn't be a massive increase unless you have your brightness really high and are also running video, this is actually caused by the combination of lte, and the screen (2 highest power consumption hardware units on the phone i believe) it causes warmth from both the radio, the and even more from the battery, which can get over 40C, if it gets hot enough youll see a warning on your screen on most stock roms and i think most custom roms too not 100% sure though, i left my phone in the car in the sun with the windows up once on mistake and when i pulled the battery out (there was a battery temperature warning on my screen) it was so hot it would have burned me if i didn't drop it immediately.
luckily i tested it against 3 other batteries and it didn't get any perm damage, it actually had the longest life out of the three, because the other two were brand new and not broken in, however if it stays at a high temperature for long, it can permanently damage the battery, or even cause it to basically not work/explode.
there are two people with this issue it could be a defect with newer nitros?

Getting hot

Anyone else's getting very hot. I already returned two rezounds for getting up to 150now my nex is up to 111 right now and all I was doing was playing around on Facebook. Most of the heat feels like it is on the top half of the phone and the screen gets extremely hot

Is your brightness up high? And also are you charging it while playing on it

Charging now wasn't then and yeah I keep brightness up otherwise the screen is way too grainy. You should be able to use your screens top levels without scolding your fingers lol just curious if this is a common thing or If I have to yet again get another phone

My phone heats up on the top part like yours but mainly when I use it while it charges or if I keep the screen awake for about 20-30+ min straight.
Edit: just like your laptop or TV or psp or any other electronic device lol

Not seen any issues on mine so far and it doesn't get as hot as my iPhone 4S when that is charging and/or using bluetooth for making calls.
yeh my phone gets quite warm also , crazy thing is when it gets warm im sure it affects the colour temp of the screen.
Mine gets hots quickly when I play Riptide a lot.
I noticed this too, but. I don't feel it since its just the top half and my hands are gripping the bottom half. I do feel it when I stick it in my pocket and my thigh gets really warm.

like right now. I literally just turned my phone on 5 minutes ago and am on wifi and I can feel the top getting hot
Rolled out from my Gnex Prime
when I got my phone a few weeks ago (GSM 4.0.1) my phone easily warms up especially at the back near the camera area. After manually updating to 4.0.2, I really noticed it was gone. Now even I am watching youtube videos for more than 20-30mins my phone doesn't warm up even a bit unlike before i got it on stock 4.0.1 in which just turning on a wifi connection and gps warms the back of my nexus without running an app.

Define overheating. Because i think the phone does quite well for how much horsepower is under the hood. Mine gets warm doing this, that and the other. The only time i was seriously concerned was watching a netflix movie over mhl and really i was really only concerned about the battery temp than the phone. The phone and its components are a big step up from phones 3 years ago. People used to whine about phones getting warm when 3g heated them up and 3g was becoming the norm. Fast forward to today and there are more powerful components packed into less space, and less ventilated at that. If you dont like your phone warming up get a dumbphone and be done with it. I think the nexus and most other smartphones do quite well. And this was before i undervolted it. I can only imagine how many useless threads will pop up about heat when quad cores come out. Personally when i upgrade next, hopefully two years from now and not the annual phone i am accustomed to, i hope a dual core cpu and gpu at 28nm or less will be sufficient and be well within the thermal windows and limits for how powerful these pocket size devices have become and dramatically changed our social lives.
Crazy world, ay?
mine gets hot up top on my ear when I'm on a call. I found at least by switching to the new 4.0.3 radio and doing a combination of over clocking + under volting it doesn't get nearly as hot anymore.
I'm talking when my battery temp is 111° and the top of it feels much much hotter than that. I'm on 4.0.2 I understand the phones will get warm but they shouldn't from ten minutes of Facebook. If I was watching Netflix using my GPS and doing so over 4G then yeah scold my hand I get that but not frickin Facebook or internet browsing or anything like that. I really like the phone and ill be keeping it but apparently won't be playing many games lol

I use a SetCPU profile to peg back the processor to ~700mhz when the temp gets over 40c

Whoa, it's overheating? You might have a defective phone. Mine gets pretty hot but the heat hasn't led to any stability issues or damage like yours. (Note: It's not overheating if there's no damage, so I'm assuming by your text that your phone got damaged)

Mine gets pretty hot but the operation of the phone has been fine. It sounds like all of the phones operate basically identical to this.
No not damaged. I leave it alone once it gets real hot. I've turn down my brightness to help prevent it a little. Def doesn't look as good lol

Q[How hot does your phone get]

My first Galaxy S3 went back due to excessive ink markings on the screen and since getting my replacement I have noticed it running hotter than I remember the first one being. The heat feels to be coming from the lower half of the screen / back of the phone.
I compared it to my friends phone and his gets just as hot. I am running FreeGS3 v0.1.0 and my friends was running stock - non rooted.
I ended up going to Sprint and the tech at the store replaced my phone with a new one out of the box and it is displaying the same behavior with temp.
I see no ill effects from this and am getting pretty good battery life for my usage, it is more of an annoyance for my phone to get so hot though. It seems a little warm for just browsing the web or FB on Wi-Fi so who knows.
It never seems to be the battery temp, but the CPU temp that climbs and is responsible for the heat.
I should point out that I had a Speck Candy Shell Case on the first phone, but that case has since been broke and returned. It is possible that my first phone got just as hot but somehow the dual layer design of the case disappated some of the heat, but I still feel it on the bottom half of the screen. My EVO LTE didn't get this hot in the few weeks I have it, and I have an Airave at home where it still heats up so I think we can rule out signal strength as a cause.
Anyone want to chime in with thoughts or suggestions?
Mine does that too, thought I was the only one.

Network related I think. Not necessarily signal strength but a poor data connection.mine gets hot as hell at the Bottem where the antenna is when my data is horrid.my roommates s2/e4gt Does the Same thing except at the top of the phone where the antenna is on that phone. Which would explain the battery life not being affected. The poorer the network performance the hotter it is. Sound familiar to anyone? Put the phone in airplane mode.and stress it in any way possible.overclock and run a benchmark while trying to play a game.what ever comes to mind.just leave in airplane mode and I bet it doesn't get nearly as hot as what your describing. I had a galaxy nexus on Verizon that rarely got hot. Where as my mother just got a sprint galaxy nexus which gets hotter than any phone I've ever felt but only with poor data speed as well. I've hit 120·F on my s3. I've seen her gnex hit around 140·F. So I'm blaming the network

Yeah I would buy that but my Epic Touch never got that hot plus I have an Airave at home. Doesn't heat up as much for me in Power Save mode with the CPU Limited. I think the CPU may be the culprit.

Idk if there's a bug, but check with betterbatterystats and see if gsiff_daemon is running at the top of the list... if it is, it's probably causing the battery to get hot, along with draining battery. You can fix it by using Root Explorer and renaming that file to gsiff_daemon.bak , it's in system/bin

I'm having this issue as well and its kinda bothersome. I was going to post a new thread (glad s I searched first). I especially notice it when playing games, especially graphically intense ones like nova 3 or mass effect. The phone gets hot--real HOT. I'm coming from an evo 4g lte and it didnt get as hot. Love my s3 but I'm concerned I'm really gonna shorten its life by running so hot.

I've tried a few methods, the one in this thread and a few others and still a no go. I even went into root explorer and renamed giskk_daemon. I honestly think it's the menu bar on the white gs3. I had the blue one and had no problem until I recently exchanged it for the white one yesterday.
