[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.

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.

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?

probably using that particular GPS software, not just GPS antenna by itself?
does it heat up if you just display GMaps with your location, without doing anything heavy in GMaps? Because I did not notice that much heat coming from using light GPS apps. Gaming - yes, some of those games are killers.

I am using Navigon software. I played Angry Birth and the same,phone was hot after 5min. I know is normal that phone is warm, but this is not warm,but hot.Galaxy S was cold compare to S II.

Of course it's NOT normal. Might be normal for SGS2 but not for others. as I've said on another thread, Navigating with GPS driving it got to 60C, you could slowly cook an egg at 60C.

Mine doesn't get especially warm, It gets well 4-5 degrees warmer when I browse the web or watch HD movies

It's think it's high screen brightness in combination with SW (high CPU load)!
Mine is never warm if brightness is kept below 50%

My screen brightnes is 0%. It is hot at the top where is CPU I gues.

How many degrees celsius is taken as very hot on the Galaxy S II?.
I was overclocking my Galaxy S II earlier and my temprature was up to 46 degrees celsius when i was running a stress test on the phone.
So i just stopped my stress test of the phone then.

How did you measure temperature?I have just battery temp. it is 42.

You can download the same stress test program as i'm using from Android Market. It's called StabilityTest v1.5.
it will test your CPU's on your Galaxy S II if you are overclocking it. But you can check the temprature even if you aren't overclocking.

the temp rise is sort of random, i can play games for hours (and its 26C here) with brightness on auto and so on, it doesnt get hot
then suddenly, it does, sometimes even when im not doing much
didnt get the time to pin point w/e thing creates that behavior
(and when i say hot ofc im talking of very very hot - which is what everyone talks about imo)
killall or restart and its good to go til it happens again

I'm running that app now. I wanted to get an idea of temperatures at stock before undervolting/clocking so I could see how much difference it made. But the phone is seriously hot to the touch, enough to be worrying about. The app's reporting 50C after 37min but it feels hotter than that to me.
Some components are designed to run hot. For example I have an ATI 4850 that happily runs 70+C at idle is rated for up to 120C. But I'm worried even if the exynos can handle these temps what about the other components? The top of the screen feels even hotter back. Could this cause damage to the display for example?
This is my first smart phone but having that much heat in such a tightly packed device seems like a recipe for failure.

You will find temps of 50 deg centigrade and more when using all resources of SGS II (e.g. nav with wikitude drive = camera on) and phone attached to car screen on a sunny hot day.
This is normal!
Touch a nav-device in action and You will find it glowing ......
But contrary to HTC HD 2 SGS II does not freeze or crash at that point.
Leave a device switched off in direct sunlight in a car and it will get hot too, but still it will work .....

my phone was getting extremely hot when benchmarking etc, this was default clock and voltages.
the phone reported it was reaching 50 degrees. thought this was "normal". this was on the firmware the phone was running outta the box.
flashed latest firmware and have since messed about with overclocking, @ 1650 my phone never got as hot as it did stock.
so if you have not done it, flash the latest FW...

So your cpu is not 1200 but 1650mHz now?

Been running tons of different ROMs on tons of different Android devices, and every once in a while there is a particular combo that gets tremendously hot.
Once had my N1 get so hot while using Co-Pilot Live and Spotify while plugged into a car charger, that it turned off and wouldn't come on again for some 5-10 minutes.. Definitely worrying.. Switched ROMs and never saw the problem again.

Does This Phone Get Hot?

I've read lots of comment about the N4 getting hot under normal use. Is this still the case or has the issue been addressed. I'm seriously considering buying this phone but I don't want a phone that gets hot.

Mine hasn't gotten to hot.
Those reporting this problem are probably a minority of all nexus 4 owners.

Yes the phone does get hot sometimes especially after 10-15 mins of continuously browsing the web on 3G+ or 3G and after 15-20 mins on wifi.. But that's for stock 4.2.2 and 4.3. After undervolting and underclocking the device using custom kernels and ROMs the phone does not get very hot.. It's between 37-40 even after playing games like nova 3 and nfs mw for an hour if you hold the phone with your bare hands and it obviously depends on your configuration.

Thin glassy phone + powerfull cpu = heat Nothing to worry about.

It gets hot, at least on stock firmware, although my definition of hot might be more sensitive than others. I don't know what it would be like talking on the phone for an hour with it getting hot next to your face, although I haven't done that. I have to use custom rom and underclock the cpu a bit, so it's not an really issue anymore. I probably will get flamed for this, but I don't recommend this device to you if you don't like phones getting hot. But I guess lots of these newer flagship phones that has thin plastic casing probably gets hot too.

With normal usage the phone doesn't get too hot or anything. If you are fond of overclocking and disabling thermal throttle you will get pretty high temperature's. Around 70 degrees celcius.

It get's hot as any other phone but because it has got a glass back you feel the heat better.

It didn't feel warm at all after undervolting and limiting heat using Trickster Mod (and has been yundervolted for the past 3 months).
Before that it could sometimes get really hot though.

Yes very hot, don't buy it.

Is your phone undervolted and temprature limited?
My temprature never goes over 40 degrees celsius, and feels rather cold most of the time.
Even with rather intensive games like NFS Most Wanted

This phone will not burn you. There isn't a real reason to consider the heat a problem. The temperature of the phone is regulated by the kernel, if it gets too hot the kernel takes measures to reduce the amount of heat being produced. This is a non issue.

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)

I've been reading about lag, bad battery, phones running hot, volume buttons sticking and so on. I must really have been lucky! I've tried duplicating the problems but can't. I play games and surf the internet and forums for sometimes an hour and no heat issue

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.

Nexus 4 Severely heating up on 3G

Hey all.
Had my N4 since the beginning but recently I'm getting quite an annoying problem.
When on 3G, as soon as I start using the phone, you can feel it getting warm but after about 10 mins of light use, its actually burning hot! It only happens on WiFi though.
I contacted Google and they made me factory reset which had no luck. Now there sending me a brand new N4 to replace it
Anyone had this issue before? I've never had any issues with my N4 before and I've had it since the beginning

It's normal. Under LTE heat is noticeably lower, so use that if you have access.

i love these my n4 gets hot threads..
to start off, what battery and cpu temps does your phone reach? dont say it feels hot, feel isnt an accurate way to measure temp, its not a way to measure temp at all actually. feel will only give you if it feels warmer or cooler the body part you are doing the feeling with. and burning hot i highly doubt, unless your hand is ice cold. so, post your battery and cpu temperatures and we can go from there.
