So I decided to test my 3D with my Shift and EVO4G in terms of heat emission on all three devices. Here are the quick results. All with max brightness.
4G - Hovers around 88-93F through normal use
Shift - Hovers around 88-90F through normal use
3d - Hovers around 88-96F through normal use
Played HIMYM for 25 minutes each. Same clip, same 960x540 resolution.
4G - 101F
Shift - 98F
3D - 103F (101F if you avoid grasping the back)
Played Crystal Defenders for 30 minutes each
4G - 101F
Shift - 98F
3D - 111F
So the 3D is running a little hotter. Everything but the Crystal Defenders scares me, but I guess it is a game after all. Here's the weird thing though. I put all 3 on the charger and when I woke up
4G - 83F
Shift - 80F
3D - 113F
This is with the AC on full blast all night (its 98F outside). The 3D was molten hot. I looked at history and around 5AM an hour after I slept it was ~78F then at 8AM it spiked and maxed out at 114F while charging. This happened from 8AM to 2PM when I woke up.
I don't get what's wrong. Everything seems pretty comparable with past phones. I'm scared it ran at ~112+ for 6 hours. It might be even be dangerous for me as it might explode at those levels.
I took mine back today and got it exchange -- though, not easily. Mine had rebooted when it got hot last week and it was at the point where the game Majhong would make it so hot I couldn't answer a call.
They tried to tell me all smartphones get hot (not as hot as this did) and it might be the GPS radio which is normal (palying Majhong? Really?) and if I would reset it and leave it stock I would probably be OK (WHAT?!).
The guy even asked if I was rooted -- which I'm not -- because I use ADW laucher! LOL!
So, I got a little loud. I told them I expected them to at least pretend to take me seriously and trust that I am not stupid about my phone. They were busy, so they exchanged it.
I'm still testing my new one.
I just got a dose of this earlier today. My gf was shopping so I sat on a bench outside and played Plants vs. Zombies. About 15-20 minutes later she called and I picked up the phone and felt like I was burning my face holding it up to talk. SUPER HOT!
That was the first time not charging that it had gotten that hot. I'm not sure if it is every time or not.
Guys just to clarify, those seem all normal (beefier hardware and whatnot) except for while it's charging.
There's a thread over at Androidforums discussing that its charging at too high of a voltage and that's the problem with the charging. People tried the extended battery and the issue disappeared for some. My phone also burns when its charging, but normally stays below 103-105.
The rest are due to screen brightness and temperatures around you (especially since its blazing hot in a lot of the US right now).
If it's reaching 110F+ on anything aside for GPS nav related stuff and heavy duty/graphics gaming (crystal defenders burns my iPhone 4 as well) then you got a problem, otherwise its normal.
If you pull the battery, it states on the label that it's safe up to 60c. That's 140F. 114 is nothing. And I'd bet the electronic parts are safer up to an even higher temperature, seeing as my PC's video card can take up to 70-75c (160ish F) without any problems.
It's warm to you, obviously. Anything above body temperature is "Warm"
Big powerful phone + no room for a big heatsink = warm phone.
Heck, I actually think the back camera is designed to be a heatsink, which would be why it feels so warm most of the time.
Also, if it's new, it does run a bit hot while the battery is in it's "Breaking in" period.
Yes. Mainly at night when charged via wall charger. Seems to not happen while charging with usb to PC.
My 3d seems to top out at 105-110 F overclocked underload. My old Samsung Moment used to be 130-140 idle........... LOL. Toasty hands during hunting season!
As annoying as it may be, I don't think this SoC is at a danger zone until around 150
mine is regularly at 45-50 deg C i think thats topping out at 125 roughly?
I left mine in the car out in coachella.... And the temp got really high... It was.120 outside that day.. Was still able to use phone... But I put it in front of the AC with battery cover off while I used it

shouldn't the 45nm gate-length of the 3vo3d result in LESS heat than the 65nm Evo OG? and, I thought it was supposed to give better battery life - what gives?
I've been noticing a good amount of heat up by the camera during moderate use. I thought this was a CM7 problem since I had been on it since day 1, but I am now on UnNamed and the problem persists. After some googling it does seem that many other people are having this problem. Not on WIFI, and not in a poor signal area either. Just wanted to see if anyone had any leads as to the cause. What is a good app for monitoring CPU usage by app?
Yes, it may get a little hot but it isn't something to worry about as far as I know. I've gamed for three hours straight and not had any problems except for a low battery life!
yeah mine gets hot near the camera during use but i dont think its a problem
I use a battery monitor.
From what I've read, it will shut off for protection. I've heard that as long as it doesn't ever get too much above 130 F, you should be OK.
Now if it constantly stays high, there may be a problem. Mine stays around 80 F most of the time and the highest I've ever seen is 99 F but i don't game much or use my camera. One thing you don't wanna do is charge it while hd gaming or charge it in a hot car. My infuse reached 146 F one time doing that.

Somehow 'Words with Friends' caused my phone to really warm up a lot. More so than I've seen with any other situation and on numerous occasions. Luckily I suck at that game and uninstalled it...
Mine is cool unless i put a thick case then itll burn up

When I first got CM7 running on this thing, I tore through the market installing the apps I'm used to. When I was finished, I noticed that it was indeed a bit warm in the area you described. It wasn't hot enough to cause discomfort, just warm enough to note.
I notice when my phone gets hot in that area when it is around 30% remaining and I charge it. I also notice that when it is charging, it really isn't charging but battery is draining. When I got home and charged it at 30%, I left it sitting there for about 30 minutes and when I checked the phone again, it was at 25%. GPS and wifi was turned off. I decided to power down the phone and remove the battery for 5 minutes. I started working fine after that. I noticed it getting hot again today when I plugged it in to charge at 40% but this time it actually was charging. I am running stock rom but rooted. Should this be a concern?
Seems as though a lot of people are having a variation of this problem. Hopefully it is addressed soon.
The CPU will always get a bit warm if it's running.
If it's getting very hot when the screen is off, you've probably got some background task wakelocking the phone.
My phone's screen gets pretty hot when I run web videos/flash videos on HSPA.
Runs a tiny bit warm when i'm running pristine 3D Tegra games on it...otherwise no.
So, i will make this blunt... This non overclocked phone gets hotter than any other mobile device i have tried...
I am already on my second one, after number one hit 125 while sitting on my desk. This one has hit 114, which is still unacceptable really, since the room is climate controlled to around 74...what happens when I use it in the summer??
Now, by virtue of need (infrastructure tether) , I am using the ICS beta, but I cannot believe it will effect it that much. I have a 3.7v battery, so that should be good.. I will admit that I am in a building that does not do well for 4g, but frankly, my phone burning itself up just searching for a signal is unacceptable as well...
I am about ready to throw in the towel and try a GNex, even though its radio problems scare me too...Any advice guys?
what apps are running, also is this while it is charging?
Just want to start with a big thanks for all of your work over on the nook boards. The overheating has been an issue since the start. I am on my third because of it. I only reach high temps when playing games. I can stream movies all day long, and never get over 110. I am waiting for an aftermarket battery that can handle the drain from this beast phone. I guess it depends on what you will use your phone for. Glad to see you here, and hope you stay. Sorry I couldn't be more help. Good luck....

Most apps won't affect temperature in any real way.
Tethering requires broadcasting wifi signal, and equivalently large wifi broadcast (broadcast SSID, and all data) at an equal speed to the ultra-fast 4g.
Now, this 4g phone (as well as ANY OTHER LTE PHONE RIGHT NOW) will overheat if you download a 300-500MB file at a fast 4g speed (like 25 MBit for instance).
Overheat. Untouchable.
Wifi tether (even on 3g) will overheat a phone if you're using a decent amount of data (rather than using it for short bursts).
My HTC Eris, I had to leave the back battery cover off, and put a cold can of soda (with a paper towl in between to stop moisture) to keep it from overheating.
The Rezound will get so hot that you literally can't touch it.
Charging WHILE you tether will make it a lot worse, as the chemical activity within the battery (to charge it) is going to increase heat. Add that to 4g cell phone connection, and the wifi antenna getting hot broadcasting, and you've got a 125 degree phone (which IS hot enough to start breaking solder points).
If you have it OFF the charger at that temperature, you will notice that the notification light is now flashing orange/green back and forth. This means that the unit is overheating and should be shut off, immediately.
Get the extended battery to hang out and wireless tether for a while. It generates a whole lot less heat if not on the charger, and seems to (maybe due to the case that has more space for air in it) not heat up quite as much, in my experience.
Tethering can overheat your phone. 4g can overheat your phone. Add charging to that, and it doesn't matter how many rezounds (or GNEXes) you get. These things have no real ventilation, and there's no indication that they're going to start designing them with good ventilation that I know of.
Good luck, power user. Users like you force them to think about their poor designs and improve them. But it definitely won't handle a lot of 4g tethering without overheating. I'd expect that, without ever even having a Rezound (even though I have one).
They say 130 is the kiss of death for the Rezound but even if you're peaking in that neighborhood I'd swap out the phone for a new one. 120-130 degrees...That's like keeping lava in your phone and hoping it doesn't melt.
I hit 130 with my Inc1, and it was fine. Just navigating, not charging, for 30 min did it lol.
Mine heats up excessively and burns thru battery even sitting idle with airplane mode enabled and GPS turned off (damn Verizon and their location agent they snuck in with the update). The issue here is:
A) I'm not using it nor touching it period for a few hours at a time and its still already below 30% battery without my having used it.
B) yes I have an extra battery but when I try to switch out batteries it goes into a bootloop and won't recognize the Sim card for the next half hour.
These are my problems. I have yet to exchange it cause let's be honest...who here enjoys setting up a whole other phone? Should I seek a replacement?

Back it up to your ext card and exchange. Don't forget to hard reset. They are sending refurbished units with prev owner data out there. Should only get hot when playing intense games or streaming lots data.
I had this heating and severe battery loss problem. There were times my phone would run fine and other times when it would lose 40% battery in 30 minutes. It seemed to be worse when I was moving around the city (changing towers???). I even had one experience where I turned the phone off and it continued to generate lots of heat until the battery died while supposedly powered off.
I tried every stock and rooted GB rom (no ICS) on XDA and a few not on XDA. I finally "fixed" it by RUU'ing my phone to the latest OTA, rerooting and reinstalling all my apps (no TiB). My phone now runs about 16 hours on a charge and only gets slightly warm (never hot) when you would expect it to.
I did a fair amount of reading and never did find an answer but my suspicion is that something between the rom and radio got out of sync resulting in the rom not controlling the radio properly. No science. Just a theory...
Hope this helps someone, somewhere. I know I've gotten lots of help from others on here.
Thanks!
Had many heat concerns/ issues with my rezounds in the past, now have a phone that games at about 115. My opinion after much research is that a 115 peak is about normal for this generation of phones (Gnex, S2, etc). Anything better than this is not the norm and if you get one that stays cooler, it's just luck. I had one that used to get around 150 so at 115, I never even notice anymore. My rule of thumb is to just keep exchanging the hot ones until you get one in the comfort zone. Unfortunately, it's just the reality we're dealing with until they start equipping better cooling solutions.
OK, first I think we need to understand if people are talking F or C when they throw out numbers like 124. If that is C, you have a seriously defective unit. If that is F, that is like moderately hot tapwater, and neither too hot to touch nor hot enough to damage solder joints. If it were, the computer I'm typing this on would be dissolving in my lap.
Welp
I have many a thread out there on this topic. I did 3 swaps for new units during my extended "no regrets" window, and this past week got 2 different refurbs for comparison. Here is my 2 cents (but based on a LOT of research and testing):
1) These phones run hot. If you look hard enough at XDA you will see people posting along the lines of "I don't know what you are talking about, I use my Rezound to chill a beer" and other such. You might be best to ignore those people.
2) There are some VERY bad Rezounds out there, but those are easily found. Those that jump to 130 straight off because they started to download some updates gotta go back. That was refurb 1.
3) My experience is that idling at 75-80 will produce 106 on a short HD game, 110-120 on a longer HD game. You might get 113 on Navigation. It will heat up to 100 on surfing (longer if you have more), but otherwise topping out at 120. If you fit within this, stop your search, and try to enjoy your phone.
Again, just my 2 cents.
I haven't done extensive testing, but I have noticed that when my phone has overheated it has always been when I left something running on it when I locked the screen. I've started hitting the home button every time I put down the phone for more than a few minutes and I haven't had many problems. I definitely get toasty when I play games while charging though.
As someone else already mentioned, the phone needs to get quite a bit hotter than most people are experiencing before it starts having problems. With how small the phones I would expect you would receive an instant 1st degree burn from touching it before the phone actually had problems. 150 C is somewhere around 302 F. For reference, I usually solder 400 F.
My first rezound got around 135 degrees I took it back the next day.

This laptop is running at 120F just looking at this website, and it has active cooling.
Imagine a 1.5GHz dual core PC and then unplug all the fans, including the one on the CPU, and then close up all the openings in the case. Do you think it might get a little warm?
Not only do you have the CPU generating heat, but the more current you draw from a battery, the hotter it gets. And we all know how this phone can draw the battery.

There is something wrong with your phone. I swap batteries instead of charging, swapping out 1 extended battery for another (got them onsale at verizon when they were 20 bucks), and the phone boots up in about a minute.
If it is bootlooping, then I would try a hard reset first, then contact verizon and tell them about it.
As far as the OP goes, if you are in a poor signal area, I have read in multiple places that phones use more battery and generate more heat if you are in a poor signal area.
Swapping this for a Nexus will probably get you no 4g at all.
I wouldn't worry about the phone unless it was consistently getting so hot that the LED starts flashing amber.
My Rezound has peaked at 140 according to System Tuner Pro. I was charging and web browsing as soon as I woke up, like what I'm doing now lol. Was on 3G. Also, I wasn't overclocked at all. Governor wasn't even on performance lol.

lol dude, there is no point in ignoring us people who say our rezounds run cold, because of the fact that there's rezounds out there that don't exhibit behavior like yours.
i've seen all of your threads, and commented in all of them, and you got 3 shotty phones, plain and simple man. my phone never reaches over 100, even with over an hour straight of screen on browsing, facebooking, youtubing, gaming etc. so there, i have a normal rezound. it's from launch day, and it's never given me any problems like that whatsoever.
so no, don't ignore us who have cool running phones, because there IS such a thing..some people just have really bad luck dealing with it.
also keep in mind that the past two phones you got WERE refurbs. you do realize the refurb pool is gonna be full of hot running rezounds, since a lot of people returned the phone due to heat problems, right?
I believe some of the Rezounds get hot due to software issues. My phone will stay room temp and run for 16+ hours on a standard battery while running any GB rom . Once I flash any ICS rom my battery averages 90 to 120 degrees. As it is charging next to me right now, it is sitting at 104 degrees while doing nothing. I could switch back to a GB rom right now and it would be sitting around 80 degrees. So I believe some if not most are software/firmware issues. I am not saying their aren't ones with hardware issues but it can't be all of them.
I have ran the OTA update and am running Senseless ICS.
After a little smooth talking to a vzw rep, I was sent a rezound in place of my Tbolt.
I love the phone and its speed but I noticed that the battery gets very hot when the screen is on. Coming from a Tbolt I can say that my phone never got over 36 degrees even when tethering for hours. The rezound gets to 38-40 from 1 hour of continuous use (screen on) but no tethering. I have the 3.7 battery. The same thing happens on custom rooms and stock.
Now, I read in tons of places that this phone gets hot but very few provide numbers.
Is this normal or did I get a lemon?
It's normal'ish. Depends on how hot it gets. If you're losing skin or smell something burning it's too hot and you need to exchange it. If it's just warm then you're probably good.
There are a couple threads on this in the forum. Just do a search for battery and will find what you are looking for.
I see threads about really really hot batteries, but mine is generally quite cool. I never use 4G really, but I can tether 3G all day long and it never really gets warm. With screen on for awhile - like playing a game or browsing the net - it does get warm but nowhere near "hot" like my old Eris used to get...
I think the rule of thumb is if it gets above 120°F you need to start taking a look at what is going on.
Well, thanks everyone.
I haven't gotten to 120 yet but im easily at 113-115.
Do you guys think its the battery, meaning should i shell out the $ for a new one since i got the phone practically free from VZW, or could it be some kind of heat sink issue and i need a new phone?
Has anyone had to replace one for heat issues or did you just change the battery and everything was normal?
I exchanged my first one for heat. Probably just could have exchanged the battery in hindsight. Mine was getting in the 140 degree range, so hot, even on the charger i would lose about 3% battery/minute, until it cooled down. My new one is running about 120 with hard use, but I've been running an overclocked kernal, but underclocking to 1.4ghz, and that seems to have helped keep it under 110 now. I'm running the 1.7 kernal on joelz senseless ICS rom, set to 1.4max in the CM9 cpu controller built into the rom.
There are other threads where this has been discussed already, but if you have a defective battery Verizon will replace it. Likewise with a defective phone.

It's an HTC thing, cheap plastic, no property heat dispersion, the batteries get hot, wait till summer
One of the biggest turn offs of HTC phones are the cheap housings they offer...plastic???!?!? Um, no thanks I'll take the heat dispersion aluminum of a Motorola

You may have a bad phone. I just had to swap mine for a new one. My old phone worked great for the first month but then started getting hot and chewing through batteries. I did some tests comparing my phone to my wifes and I would go through the battery 3x faster than hers did. Her phone was always cool to the touch too. I did try her battery as well and that's how I was able to determine it had to be the phone and not the battery.
I got and activated my DNA yesterday. Phone got very hot after charging (from the wall outlet ). I activated the phone and played with it a little and left it alone. Now it seems cooler.
Anyone else experience heat issues with the phone ? I am trying to determine if I got a defective piece or if it is a characteristic of this phone. I had a htc phone before which did Not have this problem.
Also, is the phone's temp displayed under some setting options ?
Thanks,

Same with me. It gets much hotter during wireless charging though.
Sent from my Droid DNA. 1080p never looked so sweet
I noticed this as well, it gets very warm when charging (even more so with wireless charging), and it gets warm with even light use.
the HTC DROID DNA when activated and signed into Google email it will be a lot of data to get itself restored. I'm sure you guys at it Facebook or Google Plus that right there with Poul a lot of data to pull in contacts and contact information plus have settings. I got mine yesterday any got extremely high alarming hi but over tonight is cool down it's not fully no more data which is somewhere around 3 gigabytes last night this seems to be doing fine now
Check the ratings of the wakk outlet...many HTCs have prob of over heating...go power master shows temperature...

Now that I used the phone whole day today. I still see an issue of phone heating up quite a bit when being used for longer than say 15 to 20 mins. Even playing the amira game that is included for about 10 mins causes the phone to heat up quite a bit.
I am thinking I have a defective piece
Mini review:
Overall very responsive and fast. Battery life was not too bad, my usage scenario seemed to hold up fine. Not as good as iphone ofcourse but I can live with this.
gps was fine, chrome is smooth. Problem areas for me so far are
1. Heating up of the phone'
2. low light pictures show a lot of noise compared to gs3 and iphone 5
Thanks

you should install a battery widget that shows temp to be sure. My rezound still gets up to 115 or so on 4g, but doesn't effect the performance of the phone.

Mine does the same thing, but it's more like after 5 minutes of constant use it starts to get very warm.
