Anyone returning their evo because of a overheating problem? Seems to be a serious problem and don't want it blowing up in my face. Read the article yesterday and checked mine and it charged at 4.348 mv. Or is this a software issue?
You wouldn't happen to have a eBay battery would you? Also the battery may get hot the first few charges. To reach 4.3V, well I'm not exactly sure how that's happening. Take it back I guess but if its your first charges then just give it time.
Unless the phone gives you a warning, or just shuts off its probably not overheating. You would be surprised how hot these can get and still be in a normal heat range. I tax my Evo pretty hard and it will get pretty damn hot, but never overheat hot.
What are you doing when it heats up? Are you playing games, charging, talking. Maybe some more info?
I've had mine in my pocket and noticed that some live wall papers really get the phone cooking. The My Beach one almost burned my leg! I guess my phone turned on in my pocket and it was going to town with random screen pushes. The phone was hot enough to hurt sensitve skin.
I've had my OG EVO get griddle pan hot several times. It has survived as well as the batteries. Every time I think I solved it, the next time it was something else.
Knock on wood, so far my 3VO hasn't got as hot. Yet.
next time you phone gets hot check and see how well your gps works.
there are some funky things going on with this phone.
Playing spider man and game froze the phone got extremely hot had to do a batt pull battery died in like 7 Min's
initial batt life was great like 14 hours and still had 50 percent after a week it got OG evo crappy, factory reset and juice def ultimate and batt is back to great.
Don't know if i should return for exchange.

No I'm using the stock battery and it was just plug into the wall charger and not doing anything. Don't we have 4.2v batteries? Shouldn't it not be charging anything about that?

It was just plugged into the wall charger and i wasn't using the phone. I still don't think it should be charging over 4.2v since that's what we have?

It did go to 102f but i guess that's normal but sometimes it goes to 105 or 106 while charging.... But I have the evo4g and that never chargers above 4.2v... Just kinda worried... Don't want this phone blowing up in my face.
Haven't had this issue. I've been traveling and have changed the phone quite a bit from using the phone as a game system. It does get warm after 30 mins of angry birds. Nothing extreme however.

It wont blow up on you. You should be safe at those ranges. when you start hiting 115 and 120 thats when you may want to unplug it and turn it off.
I had mine charging in the car mount last Sunday while running google nav, and the LED started blinking red and green. I assume this is the overheat indicator, although I can't find it in any documentation.
I had one weird overheating incident right after getting it activated at the Sprint store. 15 minutes later, it had been sitting on my desk and I go to pick it up and its crazy hot. I quickly pulled the back off and removed the battery, the battery was not hot, it was something behind the cameras. CPU I suppose. I waited a few minutes to put the battery back in but then it wouldn't turn on (overheating protection?). Went back to the the Sprint store for an exchange. Waited, waited. In the meantime I put the battery back in and it started up. After waiting 45 minutes with no help in sight I gave up... sigh. Sprint stores around here are always a PITA.
I haven't seen this problem again but seriously what the f? I went ahead and applied the OTA updates in case they included some fix for this.
Yeah, in car charger mine hit 114 with gps going. Took it back, better but not great with the new one 102. EVO 4g ran hot but that was self induced. Oc etc... Stock shouldn't go above 102 ever

my phone regularly gets to 105F from regular use sometimes; using the internet browser over wifi, playing games (cut the rope got the phone to 107F), charging also heats up the phone. I don't have auto syncing enabled.
is that normal operating temperature?
Disable auto synching of apps. no more overheating

My question is should a phone be charging over 4.2 when the voltage of the battery is 4.2 max? Wouldn't that greatly reduced the battery life if charged over that voltage? Anyone care to explain? Cos I'm really not sure what the implications are.

The voltage of the stock battery is 3.8V. I am surprised it would see higher voltages but it may have a variance that is +-(.4) even when charging the voltage shouldn't vary that much, but the amperage should increase instead to charge the battery and run the phone at the same time. I am not sure where you seen the voltage at though so if its an app, how accurate is that app. How often does this happen as well?
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...

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 , all of yous posting about your outrageous phone/battery temps...I tried to make mine get hot. I went outside in 96 degree heat standing in direct sunlight for 25 minutes, screen back light turned up to maximum, and playing Goldeneye on N64oid. Wow..closest I could get was 119. It was hot, but it was still quite useable. No 125/130/140/150 degree temps. Btw, to be exact, I bought my Rezound online on November 26th last year.........battery life still sucks @$$...
Oh, and Verizon car chargers are garbage...:-B

At that temp your battery's already overheating.
If you can get it that hot, I'm sure there are things you could do that would make it hotter. Try talking on it for two hours with marginal signal strength. A 125-degree phone is not a pleasant thing against your ear. And you're most of the way there -- don't think your Rezound wouldn't do it.
Maybe you should run that 119 temp against some other types of phones for a reality check, instead of just comparing it to other Rezounds.

The kernel doesn't like when you attempt to manually change the CPU speed (both up or down) so it overheats. My phone's battery mysteriously died after 2 hours of idling once because I didn't know about it.

The hottest mine ever got from use was 109 F. I left it in the car on a hot day once and when I turned it on to check temp it was at 130 F
Anyone else notice the htc one aluminum backside gets extremely hot when the cpu reaches over 100 degree. Usually this happen when I'm charging the battery or watching a youtube video. Sometimes it too hot to hold in my hand and I have to set it down and turn off the screens in hopes it cool down.
My galaxy note 2 always stay at 84 degree unless I'm playing games, but even the it doesn't feel really hot in my hand.
Yeah the metal conducts heat better so it can feel a lot hotter. Maybe a case could help.

Mine gets fairly hot with heavy use. Not too hot to hold however. It doesn't bother me. If it's getting that hot through a case I would trade it out for a new one just to be sure.

The aluminum body of the phone conducts heat a lot better than the plastic of other phones. So while it feels hot, its actually better for the phone, because the heat is going into the air (or into your hands) faster than it would with plastic.
The phone will throttle the cpu if it gets too hot, and completely shut off if it gets way too hot.

That doesn't seem normal to me. While my phone is charging, it doesn't get that hot. It also charges slowly. I'm guessing this is to preserve the battery. Even with usage, it doesn't get abnormally hot. Only when I start playing games. But it feels like normal heat. Not something I should be worrying about.

That is why aluminum is used for so many heatsinks on computers, cars and many engines. Its a great, lightweight, heat disperser. On the flip side though you feel it working with the warmth.

But this happened only 2 times now (in a row actually)... today I was charging my phone normally and it fully charged! I turned off the app BatteryGuru.. maybe that's the problem...
That blinking red light and extreme heat is a signal that the battery received "too much voltage" or extreme temperature, both can permanently damage the battery and circuits.
Do what you want, but it won't be the last time you have a problem. Also, are you using the stock charger?

Mine get hot too, when i'm using it on LTE for awhile, I guess this is normal, it wasn't that bad, my iphone5 also do the same.
Z is a little better on this.
What temperature are you guys getting. Mine is usually around 104f, too hot even with a case
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

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.

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.
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.
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

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.
I know I remember seeing you over there. 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.

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.
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.

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
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.

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.

I haven't noticed any heat problems thus far. Sometimes the back under the camera gets a little warm but nothing out of hand
It runs cooler than my gnex!
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.
