Nexus 7 could be heat issues???

My Nexus 7 gets hot!!! Playing none intense games, searching the web, charging and watching a YouTube video. Could this be hurting the device??? It's 86 degrees here where I'm from and 75 in my house. I now charge via Mac because the charger gets so hot!!! Now, I love my Nexus 7 and thank GOD my only issue is a skeptical one. So, I have a iPad 1 2 and 3 the iPad 3 gets kinda hot during intense hourly gameplay and that's it, this seams to not be able to handle the smallest task without getting hot, could it be the plastic back or maybe its okay and I'm just a little uptight about my gadgets???

Making the processor work hard generates heat! This is normal, the longer you do it the hotter it will get. Unlike laptops there is no cooling fan.
Don't worry the processor can still run safely upto temperatures where you couldn't be holding it but that's not likely to happen (unless you're hyper sensitive)

We avg 80°F indoors here. Yesterday was a warm 111°F outside...
Devices can get hot, not normally be big deal. My Rezound gets up around 115°F on a regular basis.

Your probably a little uptight with your toys. When electronics do work that's what happens.
Just like computers if your device is getting to hot it should just shut off

Okay thanks for the response. Now I feel a lot better, it's not a real issue just a could be...thanks!

If you're also charging and using the tablet at the same time, it'll also become really hot as well. Source: My Galaxy Nexus, EVO 3D, SGS2 all did the same thing.

Yeah, thanks, but I'm not doing that. Intact, I never do that and it still gets hot with normal use.

my nexus 7 was acting weird and was also getting really hot, my unit was lagging like crazy too, so i returned my unit and now am trying to find 16gb unit somewhere around here.

I have noticed that my replacement Nexus (with no screen lift) doesn't seem to get as hot as my first.

from case?
How many of you that think your N7 is running too hot.....have a case of some sort on it?
Some of the cases look like they would trap heat. I am a little surprised not to see some sort of case like a folio type that has breathing cut out sections to help dissipate heat when using for gaming and other heat producing use types.

But I thought that the rubber back would somewhat take a cases place. Anyway, I would never put a case on this.

I've been using mine for the last hour plus, and I wouldn't even say that it is warm, let alone hot.

Only intense gaming would make it warmer where as for regular use it would run fine. Even when it gets warm it doesn't get warm up to worrying degrees / level.

The back left of mine gets pretty warm. Worryingly so. Just watching YouTube does it.

Don't these things have heat sensors built in that will make the device handle itself if it gets too hot? Usually computer components can get pretty dang hot before having problems, too.

I won't use a case... but if it comes down to it, I might modify one that's open around the area that gets warm.
And using ANYTHING other than the Nexus 7 charger will take forever. You're lucky to get .5amp out of a Mac socket whereas the factory charger is 2amp.

Or maybe these things were built for the winter and not the summer. It does not feel good in the hand because the heat from normal task makes my hands sweat. Maybe it's because it's so slim and the chip inside is so powerful? Still, I don't like it.

Heat is a subjective thing... it was 94° here in western NY yesterday and I was showing off the Tegra 3 by playing Dark Meadow: The Pact. The back was a little warm, but nothing I would consider uncomfortable.

No dude! This baby gets uncomfortably hot just doing normal task. I remember when the iPad 3 got bad press for playing highly intensive games and getting a little hot, my Nexus 7 gets hot during normal task.

I'm starting to think it's because of the plastic back cover. See, if it was metal then the aluminum would play as a heat sink, but for 200$ I guess this is what you get?

overheating issue?

My phone gets pretty hot when gaming. Does this happen to anyone else?

Your phone has a quad core processor and brilliant screen inside of an all metal body. Of course its going to get hot. Other phones(my old gs3 for example ) get just as hot. You just don't notice it due to the plastic body.

Metal is a better conductor of heat than most other phones (various types of glass and plastics). It will feel warmer, even at the same temperature.
The plus side of it feeling warmer is that, ironically, the internals should be cooler, all things equal.

Well does your pc get hot while gaming ? Does the Xbox or ps3 yup so safe to assume heavy gpu tasked games will make it hot . Try to not be charging at the same time . Remember no removal of the battery so when it gets to hot we have little recourse to cool the AC works though lol
HTC-DNA,HTC-ONE,s3x2,s4-i9500

I've never had a metal phone before. Didn't even occur to me the frame would be the heatsink as well. I can breathe easier now thanks

[Q] Is your HTC one over heating?

I currently have a HTC one right now with Telus (in Canada).
I had the phone for about 3 or 4 days and I'm noticing my phone over heating quite often when I use it to talk, text, play games, etc.
With that being said, I just wanted to see if there is someone here that's encountering this exact same problem and if anyone knows what are the possible fixes for it.

This has been posted before. Your phone is made of METAL. It's going to get hotter than a plastic phone. Get a case. You'll be alright.

when you say overheating, do you mean it gets warm, or it's actually overheating and affecting the processing?
mine gets a bit warm when i'm messing with it for a while, but that happened on my old evo shift. it never seemed to have any adverse effects.

Yes, it is important to establish the difference between the phone feeling warm under load and the device overheating and it malfunctioning.

It's more than a bit warm. It gets hot. But as was said, it's metal and thin so you'll notice it more.

Heats up like a mofo

I'm betting you all have experienced this, but I find it ridiculous. If I play a game (not a specifically cpu-intensive game) for say 20 minutes to half an hour, then my phone is so hot that I find it uncomfortable to hold. It does not have specifically warm insides, which must then sound like the metal is doing what it should and lead the heat elsewhere but it's uncomfortable.
If I play for approx. half an hour, it's already way past warm. Warm would feel cold in comparison to how hot it can be. Are everyone experiencing this or is it possible I have gotten a lemon?

It's normal. It has an aluminum back. You're gonna feel some heat.

Some? We're way past that with my phone. I agree it should get warm, but not to such a degree that it gets uncomfortable to hold.

Mine used to get hot with the older builds. Haven't experienced any excessive heat on 4.2.2

Same here!

Aluminum transfers heat differently than plastic. It's gonna get hotter than plastic will. It's just how the metal is.

You need to tell us what temps your phone is hitting. We can't really help you out without that. Maybe your phone is getting hotter than a normal One, or maybe your hands are more sensitive to heat than the average user. Can't know without temps.
For example, my phone maxes out at 42/43 degrees battery temp. It's definitely warm, but not uncomfortalble to hold. Other users have said their phone temp is around this as well when playing intensive games.
If your phone gets much hotter than this, I would return it. If it doesn't, and your hands are more sensitive than ours, I would buy a case/different case and try to live with it.

The phone definitely transfers heat very well, so it seems much hotter than other phones. I don't like it either. I was in Shanghai on the weekend and this phone was making my hands sweat. I think the next big improvements we'll see with phones will be temperature and battery life. It must... These phones are becoming heaters.
Since your phone's temperature is normal, I can only suggest three things. Get a different case, root and try the elemental kernel, or undervolt your processor. Not much beyond that.

I've got two Galaxy S4's and a HTC One they all get very hot after 20 mins seems the S600 has pour thermal profile when it hits the top of it's clock speed. I would say the HTC is just a little bit hotter than the S4 most likely due to the Aluminium. Try a Flexishield case works for me to make it a bit more comfortable.

Keep phone cool while charging (wireless/wired)

Hey everyone. I'm new to the Nexus 5 community, got my phone a week ago and so far it feels like ive had it for ever. Great device and so worth my limited money.
Anyways. I have been doing these methods on all my phones and so far i haven't seen anyone else trying this.
1. Speed cool your phone
If you have a heat sink from an old pc laying around (unless its one of those huge gaming computer heat sinks) it can now have a purpose again. If your phone gets hot, simply put the heatsink copper side up and put your phone on it. about 2 minutes later your phone should be as cool as it can get without using a freezer.
2. Keep phone cool while wireless charging.
I got a wireless charger recently, and sometimes the phone doesn't get hot at all, and other times it gets VERY hot (about 115 degrees F). So instead of finding the 'perfect' position for my phone to stay cool, i found that using simple cup stands or what ever they are called, helps.
You know those things at restaurants that you put your cup on? those things. For best effect, use 2 or 3 of these, put them under your phone while your phone is on the wireless charger. I think it helps because the cardboard isn't very dense and absorbs and quickly lets off most of the heat and my phone never got over 101 degrees F yet.
3. The first method can also be used while charging your phone though a wire.
Sometimes i want to watch a movie or something while charging my phone on a wire, i simply put it ontop of the heatsink and watch the movie. Might be a bit uncomfortable, so try to found a way for it to be comfortable.
Hope this helps anyone, im still working on a way to make a home made (thin) heat sink for wireless charging.

heat sink testing
So far ive built the heatsink, its about 6 - 7 mm thick using those cardboard cup stand things mentioned above, coper wire, and silicone, and some superglue. i thought tape (specifically the adhesive) would melt under heat.
So far, i have charged my phone all the way up from 20%, temeprature hit 118 degrees F (note this is wireless charging).
Currently testing the heat sink. Charging it up from 85 %. So far at 92% and max temperature is 97F but has gone down to 96F. The heat sink is pretty warm compared to the phone (the phone is actually quite cool).
If you would like to mess around with the design this is how i built it.
Took one cardboard cup plate and put a copper coil on it. I just took about 10 inches of copper wire (thin kind) and made it into a wide coil (ill post pictures later), and then hammered it to be more or less flat. Put small amounts of superglue to hold it in place. Took the second cardboard plate, and put it on top. Used silicone to seal the edge to hold. Also add some super glue to the top of the coil to glue it to the top cardboard piece.
Simply put the heatsink under the phone while wireless charging.

Pictures of heatsink
Here are the pictures.
Ill post screenshots later of the test.

I do the same thing for wireless charging. Instead of making one, I bought a set of ceramic/porcelain/granite (I don't really know) coasters. I used one coaster for wireless charging, and four more under my laptop for when it is on the counter or table (keeps it cool and above any drinks that may spill).

I have this huge granite/porcelain slab my mom uses to beak bread. i wish it wasn't a 2 foot x 2 foot size, maybe i could have used that instead.
ALSO
so far the temperatures would go up to about 99F and then go back down to around 96...i think what happens is the phone heats up, then the heatsink takes the heat, and cools down while the phone heats up again...cycle

As I mentioned, I am not exactly sure what the material is. My guess is ceramic. I had the idea when I saw them in a store.
You can find them just about anywhere, and decorated any way you like (mine are plain). Link to Amazon
The granite slab you mentioned should work just fine. I never precisely monitored the temperature, but I know its a lot cooler.

Haha like I said that slab is huge for an oven made to bake on. So if I had something to cut me a slice I would.
I was just sitting at my PC and I saw the little cardboard things and though why not try it. I tried with two and it seemed to work okay-ish so like I used my copper heat sink I thought of putting copper in between. Took me 5 minutes to make.
But I'll definitely give the porcelain a try.

I don't recommend putting anything between the phone and the wireless charger, increased distance means less power into the phone and more wasted into the air. Also I don't think the plastic case of the phone will interface well with a metal heatsink but I admire your tenacity.
Maybe log your temps with and without and compare, though you would have to adjust values for ambient room temps otherwise a warmer day could throw off all your results.

just out of curiosity, completely. whats the point of this? heat is normal, especially while charging, and does not hurt the device. for the fun of it, i reach cpu temp shutdown purposefully all the time(105C), on all my devices, for years. heat has never ever caused any kind of damage to any of my devices. as the safety temps for battery and cpu shutdown are actually below the temps that our devices can handle before it can cause any damage.

Well looks like I have the exact opposite experience than you. All the phones I've had eventually had degraded battery's because of over heating. I had phones that would last 4 hours on an old battery and 12 on a new one. And that's just from gaming and such. Now charging is pretty much directly heating a battery. Also some people don't like picking up a piece if lava.
If you think its pointless then don't do it.

Battery degradation occurs on all Li-ion batteries. Heat has very little effect on the overall lifespan of the battery. You can expect about a 30% loss in capacity every year no matter your usage patterns.

im not planning on it. as i said the very first thing, out of curiosity.
now degraded batteries that early can happen, but its mostly because of manufacturing defects. the chances of that happening more than once in a row is fairly low. but you said multiple times. which leads me to believe that theres either something wrong with your phone physically, or maybe you are doing something wrong. as i said, on my g1(s), ion, og droid, nexus one, nexus s, galaxy nexus, nexus 4, nexus 7, and nexus 7, ive never had any issues because of heat or because of battery. i do all the testing for trinity kernel, while testing i try to "break" the kernel. part of that testing is keeping the temps right under the thermal shutdown temp for long periods of time. i have yet to see any kind of damage because of this(except for me "breaking" any test kernels).

yea, it charges "faster" before 80%, then slows down. then slows down again around 92%. oh, and that article is outdated. our batteries are a newer tech than when that article was written(2010).

Using a Wireless charger doesn't generate that much heat lol.
I don't use my device while charging it either.
