Heat on back

Has anyone else experienced a lot of heat on the back side after gaming. Is it ok to have a case if this gets to hot?

I play game a lot, sometimes it does get quite hot which is just normal and it cools down quite quickly. I also have case, to me it's not a problem as long as the phone doesn't get tooooo hot.

In my case, the one s reaches almost 40ºC when i'm playing a HD game or watching HD video like Vimeo. Is this normal?

HTCs get hot, this is normal considering the aluminum housing.

With such a thin phone heat is to be expected, especially when the processor and ram is being used heavily. Where else do you think the heat is going to go? My galaxy S2 is the same.
And yes a case should be fine, if your worried just take off the case for a bit.

[Q] Tablet heating?

Hi I had purchased a Galaxy Note 10.1 recently and have been playing around with it. A concern I had was that on the upper left backside of the device, below the silver plate on the white surface, the device feels warm compared to other areas of the tablet when using any apps. Is this normal or not?

that is close to the cpu same on mine

Hi erica, how long have you had your tablet? Has it ever really bothered you too?

"Feeling warm" is normal for anything with a modern CPU inside it. If you put your hand directly on the CPU (or the heatsink covering it) in a desktop or laptop computer you may burn your hand since it can reach huge temperatures of 60 degrees plus.
This review shows the Galaxy Note 10.1 to reach 45.9 C on one corner of the back when under maximum load:
The Samsung Galaxy Note 10.1 had no issues regarding temperature. Even after long periods of full utilization during our stress test, the Galaxy Note did not become excessively warm. While the upper left corner exhibited slight hot spots on both the front and back side with temperatures of 45.9 degrees Celsius (115.6 degrees Fahrenheit), this temperature is still rather trivial considering the fact that our test was conducted on a hot summer day. During daily use, the surface temperatures of the tablet remained comfortably cool and under 33 degrees Celsius (91 degrees Fahrenheit) at every measurement location. The internal components showed no risk of overheating in any case and even the AC adapter barely warmed up.

Since it's plastic, that'll never feel "hot", just warm.
You should rarely reach maximum load if you use well-behaved apps, though some games will tax it a bit. It's actually pretty amazing what processor power can be achieved in this thing without getting too hot or requiring a fan, thanks to the ARM architecture.

So if the tablet reaches 52 C, thats alright? I really don't know specifics like this at all but would a tablet such as the asus tf700 feel the same way? I mean heat wise on a everyday medium load?

They actually get considerably warm being they are made out of aluminum. I had the tf201 and 700. It's not too hot though but you notice it

I am using system tuner to see the cpu temperature and I am getting high as 55 C. So I am in the green right? What is the highest the temperature can be and my tablet can still have a good lifespan?

A few things:
1. When I pointed out the review of this device that said it got to 45.9 degrees, that's the surface of the outside of the case. That's different to the CPU temperature, which will invariably be hotter.
2. Tools that report CPU temperature are invariably misleading. There are so many different ways to measure it that mean different things and sensors can be calibrated differently on different devices. I'd say leave it up to the engineers that built the tablet and trust that they built it to tolerate any heat it generates, which they will have had to.
3. Aluminium of the TF201 won't be getting warmer because it's aluminium, it'll just *feel* warmer because it's aluminium - even if it were the same temperature. It conducts heat to your body more efficiently as a metal. As a result, the case itself will actually help cool the tablet better, but don't go assuming this makes aluminium cases better - the engineers would have accounted for this in their thermal design, and we're not talking about all that much heat here anyway.
At any rate, this tablet doesn't get hot enough to worry about - far, far from it. The amount of warmth you feel is normal and in a tablet like this will never get close to approaching the heat required to reduce the CPU's life (unless something goes terribly wrong or you put it in an oven or something). It's not even worth worrying about. I'd worry more than in 3-5 years' time the battery capacity will have deteriorated to the point where it'll give you noticeably less battery life - because that will happen. If you're going to worry about overheating, worry about your laptop instead. If its little fan stops, is blocked or fills with dust, it is actually *quite likely* to overheat the CPU eventually - not that you're likely to notice, as the CPU will just throttle down.

Why deny other people the chance to read these comments or contribute to the conversation? I myself put a fair bit of effort into my own comment!

Galaxy S4 GTi9505 Great!!!! But NOT too impressed about the design/material

So its been about 2 days so far and the phone is awesome....BUT....not too impressed on the plastic material design.
Should I be too worried when theres like a heat wave with temps around 100 deg F???
Will the phone "warp" or "bend" or will the plastic melt a little?
Ok ok ok....of course, I will not leave it in the car during a heat wave...Of course I will not do that. But what if I walk around with the phone in my pocket. Will the phone warp or bend a bit during those kinds of temperatures?
Battery life is awesome!!!! Well, because I disabled Wifi, NFC, and all pretty much everything including GPS and for about 2 days now, battery level is still around 70%
But, I really dont like the material and I dont know how will this be impacted during a heat wave.
Whats your take on this to all?
Thx

The OP is asking a serious question.
Mine turned into ice cream in my pocket on a hot day. Had to throw my pants out. Phone was never seen again.
But seriously, no it won't melt or warp at those temperatures. Do plastics in your cart melt or warp on a hot day? Most likely not.

LOL???
Please, this is important to me as I love this phone and I am just afraid that it would be damaged during a heat wave or extreme hot temperatures.
So seriously....Can I take my phone outside during a heat wave with those kind of temperatures?
Even if its in my pocket?
Just afraid that the screen or the phone would warp or bend.
Like I said, of course, I will NOT leave it inside a car during a hot day....But, I would like to carry it with me in my pocket.
Thx!

Just as the previous guy said, it wouldn't. If a phone actually does that on a hot day, I...I don't know what to say o_o

I'm pretty sure your phone will be fine, unless there's something you're not telling us. You don't by any chance live inside an active volcano, do you?

Every day for last 1 month was hot day here in India before the recent rains that cooled things down couple of days ago.
36-38°C was daily normal high. Did nothing to my 2 SGS4s.
It takes way higher than 100°F to melt or even soften the polycarbonate. My sister has spilled a piping hot coffee on SGS3 back which used similar material without any damage.
So no, 100F is nothing for these phones.
You will always have horror stories of people magically breaking their phones by doing nothing. Those few are there for every device. I have seen them in SGS3 forums, Note forums, HTC One forums and so on.
Those are not the norm. These phones are not the toys made to be used in nice temperate climate only.

THANKS !!!!!! For the quick help on this.
Makes me feel better now.

Don't worry, samsung qc usually already test usage in extreme temperature (-20 ~ 50 celcius). Even there is user youtube video for this test on s3.

Maybe one of the reasons for overheating

While I was changing batteries after gaming, I found that the region where SDcard is inserted was hot. Other areas were relatively very less hot, a little warm.

definitely an issue. my friend's s3 also had some issues on his sdcard.

That area is much hotter than the other areas because that is where the CPU is located. Obviously when gaming the CPU gets very hot ~55-70*C so of course the heat is gonna dissipate into that area next to the SDcard

Also don't forget that the phone is very thin which means the hardware is placed by each other so when the CPU and gpu start throllting obviously it's going to start heating since the phone is thin and the hardware is bunched up together. It's normal.. just like when you have sex you get very sweaty because you and your mate are producing heat

That's indeed a very good analogy.

[Q] Nexus 5 RAM & CPU causing LCD screen "burn"?

So, I've had my Nexus 5 since November 6th, and like most phones it gets warm when doing anything intensive. Now, I don't play very many games and really nothing too demanding. Perhaps the primary game I play which seems to warm my device up is the Simpsons Tapped Out game. All things aside, I never felt that my device got "too" warm. Battery temp never went above 100 F (37.7C) that I was able to determine, however there was most certainly a "spot" on the back located just below the camera and dead center of the device. This spot was mirrored onto the LCD area as well. Again, I never thought too much of it, however Friday night (November 16th) I noticed that when the screen was on, but showing a black or similarly dark background there was now a blue-ish circular / oval shape essentially "burned" into the screen. I don't know how else to describe it. This spot coincides directly with the location of the RAM / CPU combination on the internal board.
So, my question, has anyone else experienced distortion of their screen? Presently, while noticeable on dark screens, it's not overly damaging. However, I fear that continued normal use of the device may cause cumulative damage. I plan on contacting Google direct on Wednesday when I have some time due to work, but I'm also worried that due to the RAM / CPU placement, this may be a bigger issue than 1 unlucky phone. Perhaps improper heat shielding?
For the record, I am using the images from http://www.ifixit.com/Teardown/Nexus+5+Teardown/19016 to make my assumptions and conclusions
I appreciate any and all constructive comments!

My one got the same problem, just ordered replacement.

Maybe, the glue behind the glass had dried faster due to the higher temperature in that portion of the screen, causing a different light transmission just there, i think imho.

omg.. what a disaster of phone. If this is true then ALL of the screens will get like that if the user makes some decent use of the phone to play or so.

I highly doubt that there are different revisions of the glue behind the screen, so if one is bad, then all the nexus 5 until this was spotted will have it bad too..

Don't do that, if this starts happening to everyone, they WILL have to rma everyone's nexus 5 out there without asking.
This is by far the major problem of this phone. A true pain for google.

Been a busy day at work! Got my contact into Google as of now. Here's a pic for anyone curious

It seems definitely that the overheating of the cpu has modified the structure of the lower layer of the lcd panel and the backlight has a different effect in that part of the screen.

Are you 100% stock? i played Dead trigger 2 and TR2 yesterday for like 3 hours non stop the back of the phone was pretty warm but not blazing hot i check my screen using the app called LCD tester and i see no spots like on your device
if your 100% stock google added thermal limiting to the CPU witch could have prevented this.

I don't think it's the glue. It's probably just a bad CPU. Not all nexus 5 are created equal. Mine barely gets warm from playing 3d intensive games while on the charger so I'd just RMA yours.

Like my device. Gets warm but not hot. If your 100% stock Google added thermal limiting I think it was due to this and not burning out the CPU

blue spot
Hello i just wanted to say that i also have this problem though i do not have the blue spot where the cpu and the ram are located but just above the icon bar. How is this possible? Does the battery also get that hot?

To find out if it is screen burn, try standard screen burn reversal techniques. If it doesn't reverse at all, it's not burn

Bump, does anybody have an idea what this is? I'm considering an exchange b/c of this blue spot.. The spot seems to not be getting any bigger but it's still bugging me

I know this is a dinosaur post that Im digging up but I have a similar issue and couldnt find much info on it.
Basically my Nexus 5 took a really bad fall from someone elses hand and the screen was fine except for a bit of light bleed and colour distortion which went away in the next morning
Now if I use a 2A charger or if I play on it for too long, screen gets a pinkish hue and a spot like this appears and the phone goes a bit hot but it goes back to normal later
doesnt always appear under normal use or if I use a 1A charger
Is this an LCD problem, overheating issue of cpu, motherboard issue or display ribbon?
